Flat Roofing Across Hounslow
Flat roofs are especially common across Hounslow’s housing stock. The borough’s inter-war and post-war semis often have integral or attached garages with flat felt roofs. In addition, many had kitchen or utility extensions added between the 1960s and 1980s, almost all with flat roofs. Similarly, flat-roof garages, pram sheds and bin stores were standard on the council estates around Beavers Lane and Hounslow Heath.
Most of these structures were first roofed in three-layer bituminous felt, which typically lasts only 15 to 20 years. So where a roof has not been replaced in that time, the felt has reached the end of its life. It blisters, cracks at the joints and lifts from the deck, and then water no longer drains away. As a result, ponding water on garage roofs after rain is one of the most common complaints we hear from Hounslow homeowners.
We replace these failing roofs with EPDM rubber or GRP fibreglass. Both last much longer and also solve the recurring leaks that come with old felt.
What Our Hounslow Flat Roofing Service Includes
- Garage roof replacement — Stripping old felt and repairing the deck, then installing EPDM or GRP with proper falls. In fact, this is our most frequent Hounslow flat roofing job.
- Extension roofs — Flat roofing for existing and new single-storey extensions. We also handle the upstand flashing where the roof meets the house wall.
- EPDM rubber roofing — Single-piece membrane with no seams, so there are no joints to fail. It is also UV-stable and manufacturer-backed to 50 years or more.
- GRP fibreglass roofing — Seamless resin-and-glass system for roofs such as balconies, walkable areas and complex shapes.
- Felt flat roof repairs — Patching blisters, resealing failed laps and replacing damaged sections when full replacement is not yet needed.
- Dormer roofs — Waterproofing flat-top dormers with EPDM or GRP.
- Outbuilding roofs — Replacing old felt or corrugated coverings on sheds, workshops and garden rooms.
- Drainage improvements — Correcting falls on flat roofs that pond water, so rain drains away properly.
EPDM vs GRP — Choosing the Right System
EPDM rubber is our usual recommendation for most Hounslow flat roofs. For example, it suits garages, extensions and outbuildings where nobody walks on the roof. It is a single rubber sheet bonded to the deck, with no joints or seams to fail. It handles thermal movement without cracking and resists UV. In addition, it carries a manufacturer-backed life expectancy of over 50 years.
GRP fibreglass is, however, the better choice when the roof takes foot traffic, such as a balcony, roof terrace or access roof. This is because the cured fibreglass shell is rigid and hard-wearing.
We then assess your flat roof during the free inspection and recommend the right system.

FAQs
Hounslow Flat Roofing Questions Answered
How much does flat roofing cost in Hounslow?
Costs depend on the size of the roof and the system chosen, as well as the condition of the deck. Every Hounslow flat roof gets a free inspection and a fixed written quote — no hidden extras and no obligation.
How long does a flat roof replacement take?
Most garage roofs and single-extension roofs in Hounslow are completed in one to two working days. However, larger or more complex jobs may take two to three days.
How long will a new EPDM or GRP flat roof last?
EPDM carries a manufacturer-backed life expectancy of 50 years or more. GRP fibreglass is similarly long-lasting. Both are therefore a major upgrade from traditional felt, which typically lasts 15 to 20 years.
Can you fix the ponding water on my garage roof?
Yes. When we replace a flat roof, we build in proper falls so water drains rather than pools. Ponding water is the most common cause of early flat roof failure, so we fix it on every replacement.
Is your flat roofing work guaranteed?
Yes. Every installation comes with a written workmanship guarantee. In addition, EPDM and GRP systems carry manufacturer warranties, which we pass on to you.
