Roll of Roofing Felt at B&Q: A Practical Guide
Roofing felt rolls are a cost-effective, versatile solution for protecting roofs during repairs or as a temporary weather barrier. This guide explains what a roll of roofing felt from B&Q offers, how to choose the right roll for a project, installation basics, and practical tips to ensure lasting performance. Whether repairing a shed roof, caravan awning, or a small home project, understanding the options helps homeowners select the right material, thickness, and size for reliability and value.
What Is Roofing Felt?
Roofing felt is a bituminous or synthetic sheet designed to provide a weather-resistant layer on roof structures. It comes in rolls that can be laid over roof decking before installing tiles, slates, or other coverings, or used as a temporary protective layer during construction. Key benefits include improved waterproofing, protection during weather exposure, and a breathable layer that helps manage moisture.
Types Of Roofing Felt Available At B&Q
B&Q offers several roll types to suit different climates, roof structures, and budgets. The main categories include:
- Felt underlayment or roofing felt rolls with mineral granules for UV resistance.
- Fleece-backed options that provide added tear resistance and easier handling.
- Self-adhesive rolls for quick, cold-weather installations without show through nails.
- Standard bitumen felt rolls for traditional roofing projects.
Availability can vary by store and season, so it’s wise to check B&Q’s website or call ahead to confirm stock. Consider the local climate and roof type when choosing between mineral-surfaced and plain felt.
Key Specifications To Consider
When selecting a roll of roofing felt at B&Q, pay attention to these specifications:
- Thickness (often measured in millimetres or weight per square metre). Heavier rolls offer better durability and puncture resistance.
- Waterproofing rating and weather resistance, important for exposed roofs.
- Roll width and length to fit roof dimensions and minimize waste.
- Underlayment type (mineral surfaced, plain, or self-adhesive) and its suitability for the chosen final roof covering.
- Breathability to prevent moisture buildup under tiles or slates.
How To Choose The Right Roll For Your Project
Consider roof type, climate, and installation method. For small sheds or lean-tos, a standard bitumen felt roll with adequate thickness often suffices. For reroof projects in wetter climates, a mineral-surfaced, tear-resistant roll with higher UV stability is advantageous. If cold or humid conditions are expected, self-adhesive options can simplify installation and improve performance in challenging weather. Always ensure the roll size aligns with the roof area to reduce joints and ensure a continuous barrier.
Installation Basics With Roofing Felt Rolls
Follow these practical steps to achieve a reliable installation using a B&Q roofing felt roll:
- Prepare the roof by removing old coverings, cleaning debris, and ensuring a flat, dry surface.
- Lay starter strips along eaves to form a base line for the felt and protect edges.
- Unroll and position the felt, ensuring it overlaps at least 100–150 mm along each row, and at least 150 mm at the edges or overlaps according to product guidelines.
- Seal joints with compatible tape or cement for felt, or follow self-adhesive product instructions.
- Finish edges by trimming and securing with roofing nails or staples as required, avoiding sharp folds that could cause tears.
Safety is essential. Use fall protection on steep roofs, and follow manufacturer instructions for fasteners and adhesives. If unsure, hire a professional roofer to ensure watertight performance and warranty compliance.
Common Applications And Limitations
Roofing felt rolls from B&Q are suitable for:
- Temporary weather protection during repairs or construction.
- Low-slip protection under tiles or metal sheets on small roofs, sheds, or outbuildings.
- Underlayment beneath asphalt, concrete, or composite roof coverings in appropriate climates.
Limitations include reduced longevity under extreme UV exposure without mineral surfacing, and potential tearing on sharp edges or nails. It is not a replacement for a full, properly installed waterproof roofing system on exposed residential homes without proper overlying material.
Sizing, Availability, And Price Considerations
B&Q offers roofing felt rolls in various widths and lengths. Typical widths range from 1.0 m to 1.2 m, with lengths that vary to fit different roof areas. Prices depend on thickness, surface finish, and brand, but most rolls present a favorable cost per square meter compared with more premium underlayments. When planning a purchase, measure the roof area and add a small waste factor for overlaps and waste to estimate the number of rolls needed. B&Q frequently runs promotions, so keep an eye on online deals or in-store pricing.
Maintenance, Longevity, And Replacement
Well-installed roofing felt can protect a roof for several years, particularly when properly overlapped and sealed. Inspect the felt after severe weather for signs of wear, cracking, or lifting at the edges. If damage is found, plan timely repairs to prevent leaks. Replacement should be evaluated based on roof condition, climate, and prior installation quality. For sheds and outbuildings, consider routine checks at least once per year and after heavy storms.

Frequently Asked Questions
Q: Can roofing felt roll be used as the final roof on a house? A: No, roofing felt is typically used as underlayment or temporary protection, not a final weatherproofing layer on most traditional residential roofs.
Q: Do I need underlay when installing roof tiles? A: In many cases, yes. An underlayment provides a secondary barrier against leaks and wind-driven rain and helps protect decking during installation.
Q: How long does roofing felt last? A: Lifespan varies by product and climate but ranges from several years to over a decade for higher-quality, mineral-surfaced rolls in favorable conditions.
Q: Is self-adhesive roofing felt easier to install? A: It can be, especially in cold or windy conditions, but it may be more expensive and requires careful surface preparation for adhesion.
Using a roll of roofing felt from B&Q provides a practical option for temporary protection, underlayment, and small-scale roofing tasks. By selecting the right type, size, and thickness, homeowners can ensure an effective barrier against moisture while planning a longer-term roofing solution.
