Garage & extension roofs
Time to replace your garage or extension roof?
Garages and extensions are where flat roofs work hardest and get neglected longest. If the felt is splitting, the room below is damp, or you’ve patched it more than once, a proper replacement is the fix. Request a quote and we’ll price it up properly.
Leaking garage roof
The old felt on the garage has split or perished and water is getting in.
We strip it back and replace the felt roof on your garage so it’s watertight for years.
Tired extension roof
The flat roof over your extension is past its best and letting you down.
A full extension roof replacement in GRP, EPDM or felt, fitted to last 20+ years.
Sagging or pooling
The roof dips or holds water for days after rain instead of draining.
We re-deck and build in correct falls so the new roof sheds water cleanly.
Cold, damp room below
The room under the extension roof is cold and prone to condensation.
We can add warm-roof insulation during the re-roof to fix it for good.
Patched too many times
The garage or extension roof has been repaired over and over again.
A new roof in one go ends the cycle, cheaper in the long run than more patches.
Old and past its life
A felt roof over 15 years old is brittle and near the end of its service life.
Modern GRP and EPDM last decades, a proper upgrade, not a like-for-like swap.

Choosing the right system
GRP, EPDM or felt? The right system for your garage or extension
There’s no single “best” system for every flat roof. The right answer depends on the size and shape of the roof, the deck underneath, how exposed the property is, and your budget. We install all three and recommend whichever fits the job, never whichever earns us the most.
Once we’ve surveyed your roof, you get a fixed written quote before any work starts. We strip the old covering, check and re-board the deck where needed, then fit the right system for your roof, GRP fibreglass, EPDM rubber or torch-on felt, with correct falls built in so water always finds the outlet.
As Icopal-approved contractors, every new roof is installed to a strict standard and water-tested on completion. Photo records are taken before, during and after, and every roof comes with a 10-year written guarantee.
