The right system for your roof

A tired flat roof pooling water or showing splits and blisters is only going to get worse. The good news is that modern flat-roof systems are a world away from the felt of old — seamless, resilient and long-lasting.

We install and repair every major flat-roofing system, and — crucially — we advise you honestly on which one suits your building, its use and your budget, rather than fitting a one-size-fits-all product.

Flat roofing FAQs

What is the best type of flat roof — felt, EPDM, GRP or single-ply? +
Modern torch-on felt is cost-effective and reliable; EPDM rubber and GRP fibreglass give long, seamless, low-maintenance finishes ideal for extensions and garages; single-ply membranes suit larger and commercial roofs and carry the longest guarantees. We recommend the right system for your roof and budget.
How long does a flat roof last? +
It depends on the system. Good felt lasts around 15–20 years, EPDM and GRP can last 25–30+ years, and single-ply membranes are designed for very long service with warranties of up to 20 years or more.
How much does flat roof repair or replacement cost? +
Cost depends on size, the system chosen and access. A small garage roof is modest; a larger extension or commercial roof costs more. We survey first and give a fixed quote — no surprises.
Can you install a roof lantern or skylight on a flat roof? +
Yes. We regularly fit roof lanterns and skylights into flat-roof extensions, forming the correct kerb and weatherproof detailing so it stays watertight.
Can a flat roof be insulated to meet Building Regulations? +
Yes. We build warm-roof and cold-roof constructions with the correct insulation and ventilation to meet current Building Regs U-values.
