A new flat roof that finally stays dry.
Old flat roofs were built to last around a decade. Modern systems last far longer — if they're installed properly, with the right falls, insulation and edge detailing. That's exactly what we do.
B & S Roof Repairs installs new flat roofs across Gloucestershire in EPDM rubber, GRP fibreglass and high-performance torch-on felt, on garages, extensions, dormers, porches and outbuildings.
We strip the old covering, inspect and replace the deck where needed, correct the falls so water actually drains, add or upgrade insulation, and lay your chosen system with proper upstands, trims and outlets.
We'll recommend the right system for your roof and budget — rubber for a long-life, single-piece finish; fibreglass for a hard-wearing, walkable surface; felt where it's the practical choice — and quote it all in writing.

Why an old flat roof keeps letting you down.
If you're repairing the same flat roof every year, the covering has reached the end of its life.
Endless repairs
Once felt has gone brittle across the whole roof, patching one split just moves the leak. The repairs cost more than a new roof would.
Standing water
Sagging decks and shallow falls leave water ponding, which destroys old coverings and guarantees the next leak.
Cold, condensation-prone space
Old uninsulated flat roofs lose heat and sweat with condensation, damaging ceilings from the inside as well as the out.
A clear, methodical system — built around your time and your property.
Inspection
We assess the roof on site or from your photos — checking the cause, not just the symptom — and quote in writing.

A full inspection, a clean site, and honest aftercare advice before we leave.
The benefits you'll actually notice — and the ones that pay for themselves.
Long service life
Modern EPDM and GRP systems are built to last decades, not years — installed once, properly.
Corrected falls
We re-establish the right falls so water drains away instead of ponding and breaking the roof down.
Warmer below
Upgraded insulation as part of the works cuts heat loss and stops condensation in the room beneath.
Seamless finish
Single-piece rubber and laminated fibreglass have far fewer joints to fail than old built-up felt.

Honest advice on rubber vs fibreglass vs felt for your roof, use and budget.

Waste removed, site kept clean, and a clear written price and timescale up front.
Choosing the right flat roof system.
Each system has its place. Here's how we help you choose and how we install it.
Service Areas
EPDM rubber
A single sheet of rubber membrane, often laid in one piece on smaller roofs, with very few seams to fail. Excellent longevity and flexibility, ideal for garages, extensions and dormers. We bond it down with the correct adhesives and finish the edges with proper trims.
GRP fibreglass
A seamless, hard-wearing laminate that's walkable and takes a smart coloured topcoat. Great for balconies and roofs that see foot traffic. We lay it over a prepared deck with matched resin, matting and trims for a rigid, watertight finish.
High-performance felt
Modern torch-on felt systems are a world away from old pour-and-roll felt — multi-layer, tough and reliable, and often the practical choice for larger or more complex roofs. Properly lapped and bonded for a long life.
Decks, falls and insulation
Whatever the covering, the roof beneath matters most. We replace tired decking, correct the falls so water drains to the outlets, and build in insulation as a warm or cold roof to suit the construction and your budget.
