The Ultimate Guide to Felt Roofing Rolls: 1 Minute to Understanding Felt Roofing Benefits

Felt roofing rolls are a popular and versatile solution for protecting flat and low-pitched roofs. Often made of bitumen-impregnated fibers, these rolls provide a waterproof membrane that shields buildings from moisture, wind, and temperature changes. Homeowners, DIY enthusiasts, and contractors favor felt roofing for its affordability and ease of installation. In this guide, we’ll walk through everything you need to know about felt roofing rolls—from types and installation techniques to maintenance and design integration.

Types of Felt Roofing Rolls

There are several varieties of felt roofing rolls, each suited to different needs and climates:

1. Standard Roofing Felt – Traditionally made from organic fibers, now commonly reinforced with polyester for added durability.
2. SBS Modified Felt – Uses styrene-butadiene-styrene polymers for improved flexibility and resistance to cracks.
3. Self-adhesive Felt – Comes with an adhesive backing for simplified installation, ideal for smaller roofing projects.

Key Benefits

Felt roofing rolls stand out for their cost-effectiveness and versatility. They are lightweight, easy to cut, and can be installed with basic tools, making them suitable for sheds, garages, extensions, and more. Additionally, felt provides effective weatherproofing and can be layered for increased protection.

Installation Guide

To install felt roofing rolls, you’ll need a clean, dry surface and basic roofing tools. Here’s an overview:

1. Clear away old roofing material and debris.
2. Apply roofing adhesive or nails at frequent intervals for secure attachment.
3. Overlap joints by at least 2-3 inches to prevent water ingress.
4. Seal edges with bitumen paint or adhesive for optimal waterproofing.

For complex or large-scale projects, working with a professional or using planning software is highly recommended. As a designer, I often integrate roofing design solutions into digital layouts to visualize material choices and their aesthetic impact.Maintenance & Longevity

Routine inspection is key for prolonging your felt roof’s life. Watch for bubbling, tearing, or pooling water. Quick fixes, like patching small tears with bitumen sealant, can extend the lifespan and maintain waterproofing. Most felt roofing lasts 10-20 years when properly cared for.

Design Considerations

Felt is available in various colors and surface finishes, allowing you to coordinate your roof with the rest of the property’s design. As a designer, I recommend balancing practicality with visual appeal—choosing a style that complements exterior walls and landscape can enhance curb appeal and even home value.

Tips 1:

Before purchasing felt roofing rolls, accurately measure your roof area and account for overlaps and waste during installation. If your project involves integrating the roof with other elements (such as skylights or chimneys), plan these details out in advance to ensure seamless weatherproofing and an attractive finish.
