Comprehensive Guide to Composition Roll Roofing: Benefits, Installation, and Maintenance

Composition roll roofing is a practical and cost-effective roofing solution widely used in residential and commercial buildings across the United States. Comprised of asphalt-saturated materials rolled into sheets, it offers durability and ease of installation, making it an appealing choice for flat or low-slope roofs. This guide explores what composition roll roofing is, its benefits, installation processes, and essential maintenance tips to help property owners make informed decisions.

What Is Composition Roll Roofing?

Composition roll roofing is a roofing material made primarily from asphalt-saturated felt or fiberglass mats formed into continuous rolls. Unlike individual shingles, these sheets come in widths of 36 inches and lengths between 33 and 100 feet, allowing for quick coverage of large roof surfaces. The asphalt mixture provides waterproofing and weather resistance, while the reinforcing mats offer strength and flexibility. This combination creates a durable surface ideal for protecting structures from moisture intrusion and environmental damage.

Roll roofing can be modified with granules or coatings to enhance UV resistance and aesthetics. The surface can be smooth or granular depending on the type chosen, and it often resembles traditional asphalt shingles but in larger continuous sections.

Benefits of Composition Roll Roofing

Composition roll roofing brings a variety of advantages, particularly for projects with budget and time constraints. Key benefits include:

• Cost-Effective Solution: Roll roofing is cheaper than other roofing materials like shingles, metal, or tile, making it an economical choice for large or secondary structures.
• Quick and Simple Installation: The rolls cover wide areas with fewer seams, reducing roof penetration points and installation labor.
• Lightweight Material: It does not require heavy-duty roof framing systems, making it suitable for existing roofs.
• Water Resistance: The asphalt base creates an effective water barrier to prevent leaks.
• Flexibility and Durability: The materials bend without cracking, which resists damage from shifting frames or weather conditions.
• Maintenance Friendly: Repairs can be made easily by patching small damaged areas.

Common Types of Composition Roll Roofing

Several types of roll roofing materials cater to various needs and budgets:

How Composition Roll Roofing Is Installed

Proper installation is critical to maximize the lifespan and effectiveness of roll roofing. Steps generally include:

1. Preparation: Clean the roof surface, remove debris, and repair any damage.
2. Underlayment: Install a suitable underlayment or primer to enhance adhesion.
3. Measuring and Cutting: Roll out the roofing sheets, measure, and cut them to fit the roof dimensions accurately.
4. Attachment: Secure the sheets with nails, staples, or adhesives as recommended by the manufacturer.
5. Sealing Seams: Overlap edges by at least 2-4 inches and seal them with roofing cement or specialized tape to ensure watertightness.
6. Finishing: Inspect edges and flashing sites to ensure a complete seal and protect from wind uplift.

Safety considerations during installation include wearing protective gear and ensuring falls or accidents are avoided when working on roofs.

Maintenance Tips for Roll Roofing

Maintenance is essential for prolonging the life of composition roll roofing and avoiding costly repairs:

• Regular Inspections: Check roof surfaces at least twice a year and after storms for tears, blisters, or loose edges.
• Clean Debris: Remove leaves, branches, and dirt regularly to prevent water pooling and rot.
• Repair Damage Promptly: Patch small holes or tears with compatible roofing cement or patches.
• Maintain Flashing and Sealants: Inspect and replace sealants around chimneys, vents, and skylights to prevent leaks.
• Control Foot Traffic: Minimize walking on the roofing surface to reduce wear and tear.

Common Applications of Composition Roll Roofing

Composition roll roofing is versatile and widely used for various structures and roof types:

• Flat and Low-Slope Roofs: Frequently chosen for its waterproof qualities and ease of installation on roofs with minimal pitch.
• Sheds and Garages: Provides economical weather protection for outbuildings.
• Commercial Buildings: Applied on inventory warehouses and low-slung commercial complexes.
• Temporary or Secondary Roofing: Often used as an interim waterproofing solution during large projects.
