FAQs on Built-up Felt Roof London
Felt roofing is a professional flat or low-pitched roofing system composed of layered, bitumen-saturated polyester or fibreglass sheets. Professionally installed torch-on or cold-applied systems offer 10–20 years of durability, with mineral coatings enhancing UV resistance. Economical and quick to install, it remains a top choice for reliable waterproofing when maintained by certified experts.
We apply a three-layer system for felt roof waterproofing. The process begins with a perforated vapour control membrane bonded to the primed deck using controlled flame. A sanded reinforced felt layer is then torched onto the first, followed by a mineral-finished cap sheet (available in various colours). Each layer uses a half-lap technique, and joints are staggered with a 3–5mm overlap to prevent alignment vulnerabilities.
We select Costs that hinge on warranty duration and insulation needs. A 20-year warranty ranges from £60–£80/m². Adding insulation upgrades can elevate this to over £130/m² due to enhanced materials and labour.
We see that overlaps create potential leak points, and liquid systems offer a robust alternative.
Torch application mandates post-installation fire-watch personnel per CDM regulations, increasing safety complexity.

Beyond the standard charcoal grey, felt roofing offers versatile color options that vary by manufacturer and system type. Key choices include:
Neutral Tones: Black, slate grey, deep brown.
Mineral-Coated Finishes: Green, terracotta, blue (enhanced UV protection).
Custom Solutions: Bespoke colours (e.g., red, sandstone) for architectural alignment.

We see that properly maintained felt roofs last 10–20 years, with some exceeding 20 years through regular inspections and prompt repairs by accredited specialists. Flat roofs typically outlast pitched installations.
We install new felt that is applied over old layers after thorough debris removal and surface levelling. While small roofs (e.g., sheds) benefit from complete stripping, medium/large roofs are cost-effectively preserved via overlaying.
The choice balances roof type, performance demands (e.g., weather resistance), and budget. Consult a specialist like Denco Waterproofing to match products like mineral-coated cap sheets or fire-rated variants to your project’s requirements.
