Flat roofs in Horsforth that stay watertight
Kitchen extensions, garages and loft dormers all tend to have flat roofs, and they are often the first part of a house to leak. Our flat roofs in Horsforth are installed or repaired using EPDM rubber, GRP fibreglass or torch-on felt, depending on the roof and your budget.
We start by checking the deck. If the boards are soft or sagging, we replace them first, because a new membrane on a weak base will not last. We also pay close attention to where the flat roof meets the house, which is where many leaks begin.
We have over 20 years' roofing experience, public liability insurance and a guarantee on every job. Quotes are free.

Flat roofs on Horsforth properties
Horsforth's stone terraces and cottages often have flat-roofed rear extensions or outriggers added over the years, while the larger family homes nearby commonly have garages and single-storey additions with flat roofs. Stone homes with slate roofs sit alongside newer tiled properties, so junctions with stone walls and slate slopes need careful flashing.
We work on flat roofs throughout LS18 and in Rawdon, Cookridge, Bramley, Calverley and Kirkstall. Horsforth is covered by our Yorkshire team, who work across Leeds, York, Malton and the surrounding towns. We also handle commercial flat roofs.
Repair or replace your flat roof?
If the deck is solid and damage is in one spot, a repair can be enough. If the covering is cracked or blistered across the roof, water ponds for days, or the deck flexes, replacement is usually the better long-term option.
Call 0800 046 1159 and we will inspect the roof and give you an honest view with a written quote.
Flat roof questions in Horsforth
What is the longest-lasting flat roof option?
Properly installed EPDM and GRP both have a good reputation for durability, and modern torch-on felt systems last much longer than old single-layer felt. The quality of installation and the deck underneath matter as much as the material. We will recommend what suits your roof.
Why does my extension roof leak where it meets the stone wall?
The junction between a flat roof and a wall needs an upstand and a flashing set into the stone. If the flashing has failed or was only sealed with mastic, water runs behind it. We renew the upstand and fit a proper flashing.
Can a dormer flat roof be replaced without scaffolding?
Usually scaffolding or a tower is needed for safe access to a dormer roof. We will assess access when we visit and include it in the quote.
Can you add insulation to my flat roof?
Yes, by building a warm roof with insulation boards over the deck. This raises the roof level slightly, which may affect upstands and trims. We will explain whether it is practical for your property.
How do I stop water pooling on my garage roof?
Pooling usually means the roof has too little fall or the deck has sagged. When we replace the roof, we can add firrings to create a better fall so water drains to the gutter.
Can GRP be laid in cold weather?
GRP needs suitable dry conditions and temperatures to cure properly, so we plan installations around the weather. EPDM can be more flexible in cooler months. We will schedule the job to suit both the material and the forecast.
