Is it time?
Signs your flat roof needs replacing
A flat roof doesn't last forever. Once the covering has had its day, patching just buys a few months. These are the tell-tale signs it's cheaper to replace than keep repairing.
Cracked, blistered or bubbling felt
Splits and blisters mean the covering has gone brittle with age. Water's already getting in, or about to.
Water ponding that never drains
Standing water after every shower means the falls have failed. Ponding shortens the life of any covering fast.
Patched again and again
If you're calling someone out every year, the covering is past it. New patches just move the leak along.
15–20 years old and tired
Old felt roofs reach the end of their life. Replacing before it fails saves the ceilings and insulation below.
We'll tell you honestly. If a repair will do, we'll say so.
Replaced properly, not patched over
We strip it back and rebuild, the right way
A proper replacement isn't a new layer slapped over the old one. We strip the failed covering off, check the deck and replace anything soft, upgrade the insulation where it makes sense, and lay a new seamless membrane with the falls set to drain properly.
You end up with a roof that's watertight from the deck up, not a temporary fix that traps damp underneath and fails again in a year.
