Flat Roofs

We fit new flat roofs and carry out flat roof repairs in mastic asphalt, high-performance felt and single-ply EPDM rubber. Each system suits a different job, so we help you choose the right one for extensions, garages, dormers and outbuildings. Because we fit it with the correct falls and detailing, the roof sheds water properly instead of holding onto it.

Tired of a Leaking Flat Roof?

Old-fashioned pour-and-roll felt flat roofs blister, crack and pond water. Once they start leaking, patching rarely holds for long, since the whole covering is usually tired at once. Water sitting on a poorly laid roof is a constant threat to the room beneath, so it's not a problem to leave for another year.

Modern flat roofing is a world apart. A properly laid EPDM rubber membrane, for example, comes in large sheets with very few joints. So there's far less to go wrong. High-performance torch-on felt is another reliable option. Both give decades of low-maintenance protection, as long as the falls are laid correctly so water runs away. We fit the system that suits your building and finish every detail correctly.

Garage roofs, dormer cheeks and single-storey extensions are the flat roofs we're called to most often, usually once ponding water has started to darken the ceiling below. Because a flat roof has no pitch to shed water quickly, even a small fault in the falls can leave puddles sitting for days after rain. As a result, we check the falls and the upstands on every job, not just the surface covering itself. So a weak point at an upstand or an outlet gets fixed alongside the main covering, not left for another visit.

Flat Roof Systems We Fit

Single-ply EPDM

A tough rubber membrane in large sheets with few joints — extremely reliable and long-lasting. Ideal for garages, extensions and dormers.

High-performance felt

Modern torch-on felt systems are far more durable than old pour-and-roll felt — a cost-effective, dependable choice.

Mastic asphalt

A traditional, hard-wearing finish that suits the right job and lasts for decades when properly laid.

Proper Falls

We lay flat roofs with correct falls so water drains away instead of ponding.

A family firm with decades of flat-roofing experience behind every job.

Flat Roof FAQs

What is the best material for a flat roof? +
For most homes we recommend high-performance felt or single-ply EPDM rubber — both give a long, reliable, low-maintenance life. Traditional mastic asphalt is also excellent where it suits the job. We'll advise the best system for your roof, its size and how it's used.
How long does a flat roof last? +
A well-installed modern flat roof will typically last 20–30 years or more. EPDM rubber and quality felt systems are far more durable than the old pour-and-roll felt many people remember.
How do I stop my flat roof leaking or ponding? +
Ponding (standing water) and leaks usually come from a failed covering or poor falls. Depending on condition we either repair the affected area or, where the covering has had its day, re-cover the roof with proper falls so water drains away as it should.
What is single-ply (EPDM) roofing? +
EPDM is a tough rubber membrane laid in large sheets with very few joints, which is why it's so reliable against leaks. It's ideal for garages, extensions, dormers and outbuildings and carries a long service life.
