7 Best Shed Roofing Materials & Types in 2025
Picking the right shed roofing material isn’t always as straightforward as it sounds. Some options last for decades, others are easy to install on a weekend, and a few come down to how much you care about looks versus price. Plus, there are trade-offs in cost, lifespan, and even how much light your shed gets. We’ll break down the seven best shed roofing materials and when each one makes the most sense. Our Top 3 Picks Best for Budget Sheds Bitumen Roof Felt VIEW NOW Best for Maximum Lifespan EPDM Rubber Roofing VIEW NOW Best for Premium Aesthetics Clay Roof Tiles VIEW NOW 1. Bitumen Roof Felt Best Budget Shed Roofing Material Bitumen roof felt is one of the most common shed roofing materials. It’s affordable, straightforward to work with, and offers reliable protection against the elements. Typically made from bitumen-soaked fibers reinforced with polyester or fiberglass, it can be found in several forms – self-adhesive, nail-on, or torch-on felt. While it won’t last as long as premium options, it’s a practical choice for budget-conscious homeowners who need a solid, no-frills solution. Features Waterproof and weather-resistant for reliable protection Lightweight rolls, easy to handle and install Multiple application methods (adhesive, nails, or torch-on) Affordable compared to other shed roofing materials Optional mineral surface coatings for UV resistance Fits flat, apex, or pent shed roofs Lifespan of 10–15 years with care Pros: Very cost-effective option Straightforward installation, especially with self-adhesive felt Provides dependable waterproofing for small sheds Lightweight and easy to transport Works with a wide variety of roof designs Simple to repair or replace damaged sections UV-resistant when mineral-coated Cons: Shorter lifespan than premium materials (around 10 years) Can tear under heavy stress or extreme weather Limited aesthetic appeal (mostly dark, plain finishes) Torch-on application requires skill and safety precautions Can become brittle in prolonged heat without a top layer Less effective if water pools on the roof 2. EPDM Rubber Roofing Best Long-Lasting Shed Roofing Material If you’re looking for a shed roofing material that you won’t have to worry about replacing anytime soon, EPDM rubber is hard to beat. This synthetic rubber membrane is known for its durability and seamless waterproof coverage. It’s widely used on flat or low-pitched roofs, making it ideal for sheds, workshops, and even summerhouses. While it costs more upfront than felt, its 30–50 year lifespan makes it one of the most cost-effective options in the long run. Features Single-ply rubber membrane (typically 1.14mm thick) Installed in large, seamless sheets for watertight coverage UV, ozone, and weather-resistant Flexible in low temperatures and during building movement Resistant to hail, abrasion, and thermal shock Life expectancy of 30–50 years Often backed by a 20-year warranty Low maintenance, easy to clean Repairable if punctured Eco-friendly and recyclable Pros: Extremely long lifespan (30–50 years or more) Seamless waterproofing with no weak points Withstands harsh weather and temperature swings Very low maintenance needs Saves money over time by reducing replacements DIY-friendly with proper guidance Flexible and durable under movement Recyclable and eco-conscious Cons: Limited aesthetic appeal (plain black/grey finish) Installation must be done correctly to avoid leaks Vulnerable to sharp objects or punctures Can retain heat in hot climates Adhesive-based installation can be tricky for some DIYers 3. Felt Shingles Best Budget-Friendly Shed Roofing with Style Felt shingles give you the affordability of traditional felt but with a more decorative finish. Made from bitumen-coated sheets topped with protective granules, they come in a variety of colors and shapes – from hexagonal to scalloped designs – making them a good fit if you want your shed to look neat without breaking the bank. While they won’t last as long as premium tiles or metal, they balance price, appearance, and practicality for small structures. Features Bitumen-coated felt with embedded granules Lightweight and flexible sheets or strips Available in black, green, red, and other styles Easy installation for DIYers and tradespeople Protective against rain and UV damage Suitable for flat or pitched shed roofs Sold in interlocking strips or overlapping pieces Pros: Affordable compared to tiles or metal shingles Waterproof and UV-resistant Lightweight, reducing structural stress Easy DIY-friendly installation Available in multiple colors and patterns Simple to repair or replace when needed Provides a more polished look than plain felt Cons: Shorter lifespan than premium roofing options Needs more frequent maintenance over time Can tear or crack with age or impact Not suitable for permanent residential roofs Vulnerable if left exposed before installation Doesn’t handle heavy foot traffic well 4. Wood Shingles & Cedar Shakes Best Premium Shed Roofing for Natural Style If you want your shed roof to look as good as your home’s, cedar shingles and shakes deliver timeless appeal. Shingles are machine-cut for a smooth, uniform finish, while shakes are hand-split for a rustic, textured look. Beyond appearance, cedar’s natural oils make it resistant to rot and insects, and when properly maintained, these roofs can last 30–40 years or more. The trade-off? They’re pricier than most shed roofing materials and demand regular upkeep. Features Made from cedar, offering natural decay and insect resistance Shingles = smooth, uniform; shakes = rustic, textured, thicker Lifespan: 30–40+ years with maintenance Shakes are more durable but harder to install than shingles Provide natural thermal insulation, regulating shed temperature Eco-friendly and biodegradable, often sustainably sourced Pros: Distinctive aesthetic with upscale, natural character Long-lasting compared to asphalt or felt (30+ years) Cedar’s oils protect against rot and pests Adds thermal insulation for cooler summers and warmer winters Can handle severe storms and high winds Environmentally friendly, renewable resource Cons: High upfront cost, especially for shakes Require ongoing maintenance (cleaning/treating every 2–4 years) Fire risk unless specially treated Susceptible to splitting, curling, or darkening if neglected Shakes require professional installation and extra underlayment 5. Polycarbonate Sheets Best Shed Roofing for Light & Versatility Polycarbonate sheets are a great choice if you want a shed roof that lets

Guide To TPO Roofing [Everything To Know]
Flat and low-slope roofs have their own set of challenges, and not every material can handle the job. That’s where TPO roofing has made a name for itself – offering energy savings, watertight seams, and a balance of cost and performance that property owners pay attention to. We’ll break down exactly what TPO roofing is, how it stacks up against other options, what it costs, and whether it’s the right fit for your roof. Key Notes TPO reflects up to 80% of UV rays, significantly reducing cooling costs compared to dark membranes. Installation costs range $4.50-$16 per sq ft, with heat-welded seams critical for waterproofing. Lifespan averages 15-20 years, shorter than EPDM but more energy-efficient than rubber. Best suited for flat/low-slope roofs under a 3:12 pitch on commercial and modern residential buildings. What is TPO Roofing? TPO stands for Thermoplastic Polyolefin, a single-ply roofing membrane that’s been around since the 1990s. It’s made from a blend of polypropylene (a thermoplastic polymer) and ethylene-propylene rubber (a synthetic elastomer), reinforced with a polyester scrim. The result: A lightweight, flexible, and durable sheet designed to cover flat or low-sloped roofs. A few key things about its composition: The polypropylene gives TPO its thermoplastic properties, allowing seams to be heat-welded for watertight joints. The ethylene-propylene rubber adds flexibility and resilience against temperature swings. Most membranes come with UV stabilizers and abrasion-resistant compounds to hold up under harsh sunlight. Unlike PVC, TPO is chlorine-free and recyclable, which earns it points on the eco-friendly front. Key Features & Benefits of TPO Roofing Why has TPO roofing become so popular? A handful of benefits stand out: Energy Efficiency: TPO membranes are usually white or light-colored, reflecting up to 80% of UV rays. This reduces roof surface temperatures and helps cut cooling costs. Durability: Resistant to punctures, tears, and dirt build-up, with strong heat-welded seams. Flexibility: Performs well across temperature ranges – even as low as -50°F. Eco-Friendly: Recyclable, chlorine-free, and compliant with energy-efficient building standards like Energy Star and LEED. Low Maintenance: Less upkeep than some other roofing systems, especially if installed correctly. TPO Roofing vs. Other Membranes TPO isn’t the only single-ply roofing option. Here’s how it stacks up: TPO vs EPDM (Rubber Roofing): EPDM can last 40–50 years and is easier to install thanks to adhesive seams, but it’s usually black (absorbs heat) unless coated. TPO, while not as long-lived, is reflective and more energy efficient. TPO vs PVC: PVC offers excellent chemical and fire resistance but contains chlorine and plasticizers, which raise environmental concerns. TPO is greener and usually less expensive, but PVC tends to perform better in very hot or chemical-heavy environments. Quick Snapshot: TPO: Affordable, energy-efficient, recyclable. EPDM: Long lifespan, easier install, less reflective. PVC: Strong chemical resistance, higher cost, less eco-friendly. Applications of TPO Roofing TPO was developed with commercial buildings in mind, but it has crossed over into residential use too. Commercial/Industrial: Warehouses, office buildings, and manufacturing facilities with wide, flat roof spans. Residential: Modern homes with flat or low-slope roof designs benefit from TPO’s energy savings and watertight seams. Best for Roofs: Slopes under 3:12 (around 14 degrees). Beyond that, shingles, tiles, or metal are usually better options. TPO also pairs well with solar panels and green roofing systems since its reflective qualities help optimize energy performance. TPO Roofing & Climate Suitability TPO performs differently depending on climate: Hot Climates: Excels here thanks to reflectivity. Buildings stay cooler, HVAC systems work less, and energy bills drop. The caveat: in extreme, prolonged heat, some lower-quality TPO can degrade faster. Cold Climates: Flexible even in freezing conditions, handling freeze-thaw cycles well. Proper installation and drainage are critical to prevent ice dams or seam stress. Humid/Coastal Areas: Works fine, but PVC might be a stronger choice where saltwater, oils, or harsh chemicals are present. TPO Roofing Cost TPO is often praised for its balance of cost and performance. Typical ranges (materials + installation) run $4.50 to $16 per square foot, with most projects falling between $5 and $12. Cost Breakdown: Materials: $1 – $2.50 per sq. ft. Labor/Installation: $2.50 – $7 per sq. ft. Insulation/Components: $0.50 – $4 per sq. ft. Old Roof Removal (if needed): $1 – $2 per sq. ft. Example A 1,500 sq. ft. commercial roof can run anywhere from $6,500 to $24,000 depending on factors like thickness, insulation, and local labor rates. Compared to others: EPDM: Similar or slightly lower cost PVC: More expensive than TPO Installation Methods There are three main ways to install TPO roofing: Mechanically Fastened: Attached with screws and plates. Cost-effective and good for high-wind areas but leaves visible fasteners. Fully Adhered: Glued down with adhesives. More expensive but provides a smoother look and stronger resistance to wind uplift. Ballasted: Held down with gravel or pavers. Less common and requires a deck strong enough to handle the weight. No matter the method, heat welding seams is critical. Done right, it creates a seamless, watertight bond. Done poorly, it’s a recipe for leaks. This is why professional installation is highly recommended. Lifespan & Performance TPO roofing usually lasts 15–20 years, but with quality installation and maintenance, it can stretch to 25–30 years. What shortens lifespan: Poor workmanship (bad seam welding, uneven adhesion). Harsh climates (extreme UV or prolonged heat). Heavy foot traffic or rooftop equipment. Ponding water from poor drainage. What extends lifespan: High-quality membranes with UV stabilizers. Professional installation. Regular inspections and quick repairs. Moderate climates with minimal rooftop stress. Maintenance & Repairs Like any roof, TPO needs regular care: Inspect at least twice a year plus after storms. Clean dirt, algae, and debris with low-pressure washing. Keep gutters and drains clear to avoid ponding water. Check flashing and seals around penetrations. Fix punctures or seam issues quickly with welded patches. Repairs are fairly straightforward for pros. Damaged seams can be re-welded, and punctures patched. DIY isn’t recommended since hot-air welders and know-how are essential. Key Considerations Before Choosing TPO Roofing Before committing to TPO, weigh
Guide To Rolled Roofing | Everything To Know
Not every roof needs a lifetime investment, and not every project calls for architectural shingles or sleek metal panels. Sometimes you just need something practical, fast, and affordable to keep the rain out. That’s where rolled roofing comes in. It’s not fancy, but it serves a purpose – and knowing when it’s the right choice matters. We’ll cover everything you should know about rolled roofing, from costs and types to installation and alternatives. Key Notes Five main types range from basic asphalt rolls (5-10 years) to EPDM rubber (20+ years). Best applications: flat/low-slope roofs on garages, sheds, and secondary structures under 4:12 pitch. Total installed costs run $2.00-$5.50 per sq ft including materials and professional labor. Lifespan averages 5-15 years, requiring more frequent replacement than shingles or metal. What is Rolled Roofing? Rolled roofing is an asphalt-based roofing material manufactured in long rolls, typically 36 inches wide and 33–36 feet long. One roll covers about 100 square feet of surface area. Unlike shingles, which are laid in overlapping rows, rolled roofing is applied in wide sheets, creating a continuous, waterproof membrane when properly installed. It’s made from similar ingredients to asphalt shingles – fiberglass or felt saturated with asphalt, then topped with protective mineral granules – but comes in a simpler, more lightweight form. Because it installs so quickly, it’s a go-to choice for smaller projects or budget-conscious roofing jobs. Types of Rolled Roofing Not all rolled roofing is created equal. Here are the main types you’ll encounter: Asphalt Roll Roofing Standard and affordable. Made from asphalt-saturated felt or fiberglass with mineral granules. Lifespan: about 5–10 years. Best for sheds, porches, and other secondary structures. Modified Bitumen Roll Roofing Asphalt mixed with plastic or rubber modifiers for added flexibility. Can be installed with adhesive, nails, or heat (torch-down). Lifespan: closer to 15–20 years. More durable option for low-slope roofs. Rubber Roll Roofing Made from recycled tires and other materials. Flexible, budget-friendly, and eco-conscious. Performs decently but usually falls short of modified bitumen in durability. EPDM Rolled Roofing Synthetic rubber material commonly used in commercial roofing. Extremely resistant to UV and weather. Lifespan: 20+ years. More expensive but highly durable. TPO Rolled Roofing Thermoplastic polyolefin membrane. Requires heat-welded seams, making it more complex to install. Lifespan: 20+ years. Popular for commercial flat roofs. Other Variations Fiberglass roll roofing (lighter and stronger than felt-based). Peel-and-stick rolls for quick DIY projects. Pros: Low cost Quick installation (hours, not days) Lightweight and easy to transport Waterproof when properly installed Works well for sheds, garages, and flat roofs Cons: Shorter lifespan (5–15 years) Limited aesthetics (flat, plain appearance) Less durable in harsh weather Higher maintenance needs Not suited for steep roofs or high-visibility areas Where and When to Use Rolled Roofing Rolled roofing is best in very specific situations. It shines when: Low-slope or flat roofs: Works best on slopes between 1:12 and 4:12. Secondary structures: Garages, sheds, porches, carports, and barns. Temporary solutions: Emergency repairs or quick protection during renovations. Budget projects: When cost matters more than aesthetics. Where it shouldn’t be used: Steeply pitched roofs (3:12 and above). Roofs prone to ponding water or poor drainage. High-end homes where curb appeal is a priority. Cost of Rolled Roofing Rolled roofing is one of the cheapest roofing systems available. Here’s what to expect: Material cost: $0.50–$1.50 per sq. ft. Installation labor: $1.50–$4.50 per sq. ft. Removal of old roofing (if needed): $1.00–$2.00 per sq. ft. Installed total: $2.00–$5.50+ per sq. ft. For a 1,200 sq. ft. roof, that’s about $2,500–$4,800 professionally installed. Cost Comparison Roofing Type Price Range (per sq. ft.) Rolled Roofing $2–$5.50/sq. ft. Asphalt Shingles $3–$7/sq. ft. Metal Roofing $8–$14/sq. ft. Tile Roofing $10–$20+/sq. ft. Lifespan, Durability & Maintenance Rolled roofing usually lasts 5–15 years depending on material type and climate. That’s shorter than shingles (15–30 years) and far less than metal (40+ years). Factors that shorten lifespan: Extreme sun or heat (cracking, drying out). Freezing climates (brittleness, seam separation). Poor installation or lack of drainage. Factors that extend lifespan: Using higher-grade materials like modified bitumen or EPDM. Professional installation with proper sealing. Routine maintenance: inspections, cleaning, patching cracks. Maintenance Checklist: Inspect twice a year and after storms. Remove debris and clean gutters. Patch cracks, re-seal seams, and apply protective coatings. Installation of Rolled Roofing Preparation: Clean and repair roof deck. Add underlayment and drip edges. Methods: Adhesive (cold-applied): Easy and mess-free for small jobs. Peel-and-stick (self-adhered): Great for quick DIY installs. Torch-down: Professional-grade and durable but risky for DIY. Nail-down: Less common, used mainly for reinforcement. Common DIY Mistakes: Poor surface prep. Skipping underlayment. Incorrect overlaps or sealing. Using in bad weather. DIY vs Professional: DIY: Possible for small sheds and garages. Professional: Recommended for larger or occupied structures. Key Advice for Homeowners Rolled roofing makes sense for certain projects, but not all. If you’re re-roofing a shed or need quick protection, it’s a solid choice. For your main home, shingles or metal will likely serve you better in the long run. Always weigh the upfront cost against long-term value, and if you’re unsure, get a professional opinion. Installation and material quality matter more than most people realize. Need The Right Roof For Your Home? We’ll inspect & compare options to find the best fit. BOOK YOUR FREE APPOINTMENT Frequently Asked Questions Can rolled roofing be painted or coated for longer life? Yes. Applying reflective or elastomeric roof coatings can help protect rolled roofing from UV rays and extend its lifespan. It also improves energy efficiency by reducing heat absorption. Does rolled roofing come in different colors? Most rolled roofing is black or gray, but some products are available in green, brown, or white. Color options are limited compared to shingles or metal roofing. How do you know when rolled roofing needs replacement? Look for cracks, blisters, curling edges, or granule loss. Frequent leaks or large soft spots usually mean it’s time for a full replacement rather than patching. Is rolled roofing allowed by building codes everywhere? Not always.
Rolled Roofing vs Shingles | Cost & Applications
When it comes to roofing, not every option is built for the same job. Rolled roofing is quick and inexpensive, often used on garages or sheds, while shingles are built to last decades and bring real curb appeal. Both have their place – but the right choice depends on your roof, budget, and plans. We’ll compare rolled roofing vs shingles in terms of cost, applications, and long-term value. Key Notes Rolled roofing costs $1.50-$2.50/sq ft but lasts only 5-10 years vs shingles at $3.50-$10.00/sq ft for 20-30+ years. Rolled roofing works best on flat/low-slope roofs for garages and sheds; shingles suit pitched residential roofs. Shingles provide superior weather resistance against wind, rain, and UV damage in all climates. Installation complexity differs: rolled roofing allows DIY application while shingles require professional installation. What Is Rolled Roofing? Rolled roofing is exactly what it sounds like: long rolls of asphalt-based roofing material, typically 36 inches wide, used to cover flat or low-slope roofs quickly. It’s usually made from asphalt-saturated felt or fiberglass topped with a mineral coating. You’ll usually see it on garages, porches, sheds, or barns – not homes. It’s a one-layer, no-frills solution that gets the job done fast and cheap. But it’s not known for its looks or longevity. Lifespan averages 5–10 years, and it’s more vulnerable to harsh weather. Pros: Budget-friendly Fast to install Lightweight Low material waste Cons: Short lifespan Limited curb appeal Lower weather resistance What Are Asphalt Shingles? Asphalt shingles are the go-to choice for residential homes. They come in pre-cut, individual pieces (usually 12×36 inches) made from fiberglass mats soaked in asphalt and topped with ceramic granules. They come in different styles – 3-tab, architectural, and luxury shingles – and they’re layered to create a textured, water-shedding barrier. Pros: Long-lasting Better curb appeal Available in many colors and styles Good in all climates Cons: Higher upfront cost More complex installation Heavier than rolled roofing They’re built to last, typically 20–30 years or more depending on quality and installation. Key Differences: Rolled Roofing vs Shingles Let’s break down the core differences: Feature Rolled Roofing Asphalt Shingles Material Format Large rolls (36″ wide) Individual pieces (12×36″) Roof Type Flat or low-slope Pitched roofs Lifespan 5–10 years 20–30+ years Installation Fast, one-layer Slower, multi-layer Aesthetics Basic, minimal color options 3D texture, curb appeal Weather Resistance Moderate High (UV, wind, hail, rain) Cost (Installed) $1.50–$2.50/sq ft $3.50–$10.00/sq ft DIY-Friendly? Yes Not recommended Rolled roofing is the quick fix. Asphalt shingles are the long game. Cost Comparison: Rolled Roofing vs Shingles Rolled Roofing Costs: Materials only: $0.30–$1.00/sq ft Installed: $1.50–$2.50/sq ft Labor: Typically $1–$2/sq ft Asphalt Shingle Costs: 3-tab shingles: $3.50–$5.00/sq ft installed Architectural shingles: $5.00–$7.00/sq ft Luxury shingles: $8.00–$10.00+ per sq ft Labor: Often $3–$5/sq ft due to complexity What Homeowners Forget To Budget For: Tear-off and disposal of old roofing Underlayment Flashing Decking repairs Permit costs Shingles cost more upfront, but you replace them far less often. Rolled roofing may be cheaper day one, but over 20 years, you’ll likely replace it twice. Performance in Different Climates Rain: Shingles win hands down. Their overlapping layers are built to shed water. Rolled roofing has seams that can fail over time. Snow: Shingles work better on pitched roofs that let snow slide off. Rolled roofing on flat surfaces can collect snow, ice, and water – leading to damage. Wind: Heavier shingles, especially architectural ones, resist wind uplift better. Rolled roofing is lighter and more prone to peeling in high winds. Sun/UV: Shingles have UV-blocking granules. Rolled roofing breaks down faster under strong sun. So if you’re in a region with serious weather swings, shingles are worth the upgrade. Best Use Cases for Rolled Roofing Rolled roofing shines when: It’s functional. Affordable. Temporary. And best used where no one’s going to judge your roof. Best Use Cases for Asphalt Shingles Asphalt shingles are the better choice when: You’re working on a residential pitched roof The home’s curb appeal matters You plan to stay long-term You need a roof that lasts 20–30 years You live in a climate with snow, wind, or heavy rain For most homes, shingles just make sense. Common Mistakes to Avoid Using rolled roofing on steep pitches. It’s not built for it. Water will find a way in. Skipping underlayment. Even for budget jobs, skipping the moisture barrier leads to problems. Choosing based only on price. What’s cheap now might cost more later. Ignoring climate. Rolled roofing in storm-prone or sunny areas won’t hold up well. DIY without experience. Rolled roofing seems easy – until it leaks. Shingles need a pro. Overlooking aesthetics. Especially if you plan to sell – roof appeal can boost resale value. Need Help Choosing The Right Roof? Get expert advice tailored to your home and budget. BOOK YOUR FREE APPOINTMENT Frequently Asked Questions Can you layer new rolled roofing over old rolled roofing? Yes, in some cases you can install a new rolled roof over an old one if the surface is clean, flat, and in decent condition. But adding another layer can reduce lifespan and may void warranties. Do either of these roofing types qualify for energy efficiency tax credits? Most standard asphalt shingles and rolled roofing do not qualify. However, certain ENERGY STAR-rated reflective shingles may be eligible depending on local or federal programs. Is rolled roofing waterproof? It’s water-resistant but not fully waterproof long-term. Seams can degrade over time, especially on flatter roofs, making it less reliable than shingles in heavy rain zones. Conclusion Choosing between rolled roofing vs shingles comes down to what you need most – speed and low cost, or long-term durability and curb appeal. Rolled roofing is practical for sheds, garages, and other low-slope projects where looks don’t matter and budgets are tight, but it won’t last more than a decade. Shingles, on the other hand, suit residential roofs where appearance, resale value, and weather protection matter, often holding up 20–30 years or more.

Modified Bitumen vs Roll Roofing | Cost & Applications
Flat or low-slope roof projects come with plenty of decisions, and choosing the right material is one of the big ones. Modified bitumen and roll roofing both show up as options, but they serve very different needs. Whether you’re looking for long-term durability or something quick and cost-effective, we’ll break down what each option brings to the table so you can make the right call for your roof. Quick Overview: Modified Bitumen vs Roll Roofing Feature Modified Bitumen Roll Roofing Lifespan 15–30 years 5–15 years Installation Professional, multi-layer DIY-friendly, single-layer Materials Polymer-modified asphalt Asphalt felt or fiberglass Weather Resistance Excellent Basic Cost Higher upfront Lower upfront Best For Long-term protection Temporary/small structures What is Modified Bitumen Roofing? Modified bitumen is a type of asphalt roofing that’s been, well, modified – by adding rubber or plastic polymers to improve its strength, flexibility, and weather resistance. It’s usually installed in two or three layers using heat (torch-down), cold adhesives, or self-adhesive membranes. Those layers make it incredibly resilient, and with proper installation, it can last 20+ years. Best for: Commercial buildings, flat-roofed homes, garages, and any structure where durability and waterproofing matter. What is Roll Roofing? Roll roofing (or rolled roofing) is a more basic asphalt-based product that comes in large rolls. It’s often made of asphalt-saturated felt or fiberglass with a top layer of mineral granules for UV protection. It’s usually applied in a single layer and either nailed, glued, or self-adhered. It’s easy to install – especially for small or temporary structures – but it just doesn’t hold up as well long-term. Best for: Sheds, garages, low-cost or temporary buildings, and quick patch jobs. Materials & Construction Differences Modified Bitumen Materials: Polymer-modified asphalt (SBS or APP) Reinforcement layers like polyester or fiberglass Multi-ply systems (2- or 3-layer) Roll Roofing Materials: Asphalt-saturated organic felt or fiberglass Coated with asphalt and topped with mineral granules Single-layer application The added polymers in modified bitumen (such as SBS for flexibility or APP for UV resistance) give it a serious edge in tough climates. Roll roofing, however, is more brittle, more prone to cracking, and less protective—especially over time. Installation Process: Time, Tools & Skill Required Modified Bitumen Installation: Labor-intensive and best left to pros Requires special equipment: torches, rollers, safety gear Methods: torch-down (open flame), cold adhesive, or self-adhesive sheets Seams are sealed with heat or adhesives for waterproofing Takes longer but creates a tough, layered barrier Roll Roofing Installation: DIY-friendly and quick Rolled out in strips and fastened with nails or adhesives Seams sealed with roofing cement Requires basic tools: hammer, utility knife, cement Less time, less hassle – but lower durability Cost Comparison Roofing Type Installed Cost (per sq ft) Labor Materials Modified Bitumen $4.00–$7.50 $2.30–$4.00 $0.70–$2.20 Roll Roofing $2.00–$5.50 $1.50–$4.00 $0.50–$1.50 Modified bitumen has a higher upfront price tag, but that comes with significantly longer lifespan and better performance. Roll roofing is more affordable to install, especially if you’re doing it yourself, but the total cost over time often adds up. Don’t forget hidden costs: Roof deck prep, tear-off, flashing, permits, and potential safety measures (especially with torch-down) can add to the final number. Durability, Lifespan & Maintenance Modified Bitumen: Lifespan: 15 to 30 years Resistant to cracking, impact, UV damage Easy to maintain and patch professionally Requires occasional inspection and sealing Roll Roofing: Lifespan: 5 to 15 years More prone to granule loss, cracking, and leaks Requires frequent patching, especially in bad weather Shorter service life means more frequent replacement Weather & Climate Performance Extreme Temperatures: Modified bitumen (especially SBS) stays flexible in freezing temps and resists cracking. Roll roofing tends to become brittle in cold weather and can crack under thermal expansion. Waterproofing: Modified bitumen excels with welded seams and multi-layer waterproofing. Roll roofing provides basic protection but is more vulnerable to leaks. UV Protection: Modified bitumen with APP polymers and reflective coatings handles sun exposure well. Roll roofing degrades faster in direct sunlight. If you live somewhere hot, cold, wet, or windy (so, almost everywhere), modified bitumen is going to give you more peace of mind. Roof Slope, Structure Size & Compatibility Roof Slope: Modified bitumen works great for low-slope and even some steep-slope roofs. Roll roofing should only be used on very low slopes – ideally under 3:12. Building Size: Modified bitumen is suited for large or small buildings and can cover wide flat roofs efficiently. Roll roofing is better for small surfaces – like garden sheds, carports, or lean-tos. Trying to use roll roofing on a large home or commercial roof is like putting bicycle tires on a pickup truck. It might hold up briefly, but it’s not built for it.

Get expert advice based on your roof and budget. Book Your Free Appointment Frequently Asked Questions Can modified bitumen or roll roofing be installed over an existing roof? Modified bitumen can sometimes be installed over one existing layer if the surface is sound and local codes allow it. Roll roofing is generally used for new or temporary roofs – overlaying it isn’t recommended due to seam and adhesion issues. Are there different colors or finishes available for either roofing type? Modified bitumen comes in a range of surface finishes, including reflective coatings and mineral granules in different colors. Roll roofing also comes in limited colors, but most are standard grey or black with fewer aesthetic options. Does either roofing type qualify for tax credits or energy rebates? Some APP-modified bitumen systems with cool roof ratings may qualify for local energy efficiency rebates. Roll roofing usually doesn’t qualify due to lower reflectivity and shorter lifespan. How noisy are these roofs during rain or hail? Both roofing types are quieter than metal roofing, but modified bitumen tends to dampen sound better thanks to its layered
