Flat Roof Installation and Replacement across Greater London
Flat roofs cover a large share of London homes: rear extensions, garages, dormers, porches and bay roofs. When one starts to fail, water usually reaches the room below before anything looks wrong from the ground. Ashlar Roofing replaces and repairs flat roofs in felt, EPDM rubber and GRP fibreglass, so you get the system that suits the size, shape and use of your roof, not whichever material a single installer happens to prefer.
A flat roof is only as good as what sits under the finish. We check the deck for rot or movement, set falls so rainwater runs to the outlet instead of ponding, and look at whether your roof would benefit from a warm roof build-up with insulation above the deck. Outlets, upstands, trims and the junctions against walls are all detailed carefully, because these are the places where flat roofs most often start to leak.

Why choose us
Why Choose Ashlar Roofing for Flat Roofs
Three Systems, One Firm
We work with felt, rubber and fibreglass, so the recommendation follows your roof and not a single product.
Attention to the Deck
Problems under the covering are dealt with before the new roof goes on, so the finish is never laid over rot.
Drainage Planned In
Falls and outlets are set so water leaves the roof quickly, which is what keeps a flat roof watertight in the long run.
Scope Agreed Up Front
The work and the price are set out in a quote agreed with you before work starts.

Pricing
What Affects the Cost of Flat Roofs
The cost of a flat roof depends mainly on:
- The roof area and how easy it is to reach
- Which covering you choose: felt, EPDM rubber or GRP fibreglass
- The condition of the deck and how much of it needs replacing
- Whether insulation is added to create a warm roof
- The number of outlets, rooflights and wall junctions to detail

How We Carry Out Flat Roofs
The main stages of the job, from the first inspection to the final check.
Survey the Existing Roof
We look at the covering, the deck, the falls and the drainage, and ask how you use the roof. Photos sent on WhatsApp help us prepare before the visit.
Strip and Prepare
The old covering is removed and the boards are checked. Any soft or rotten decking is replaced so the new roof has a sound, level base.
Build Up and Cover
Insulation, firrings or tapered boards go on where needed, then the chosen felt, rubber or fibreglass system is laid to the manufacturer's method.
Detail and Finish
Upstands, outlets and edge trims are completed and sealed. We review the completed work with you and confirm everything has been done as agreed.
