A new flat roof that’s built to last
Flat roofs got a bad name from old felt roofs that leaked within a few years. Modern materials are very different. Fitted properly on a sound deck with the right falls, a new flat roof will keep the rain out for many years.
Allen Roofing has flat roofing specialists who install every common system. We use good-quality materials so your flat roof performs as it should. We’ll recommend the right option for your building and budget, not whatever is easiest for us.
Flat roofing systems we install
EPDM rubber roofing
A single seamless sheet of synthetic rubber. It is flexible, handles temperature changes well and has very few joints to fail. It’s a popular choice for extensions and garages.
GRP fibreglass roofing
Glass-reinforced plastic laid in liquid form and cured into a hard, seamless finish. It is strong and neat, which makes it ideal for roofs you can see or walk on occasionally, and for awkward shapes.
Felt (torch-on and cold-applied) roofing
Modern multi-layer felt systems are far tougher than the old single-layer felt. They are a proven, cost-effective option for many buildings.
Lead flat roofs
Traditional lead for bays, porches, dormers and heritage buildings, laid with rolls and drips by roofers skilled in leadwork, including lead welding.
What a new flat roof from us includes
- Stripping the old covering and checking the deck
- Replacing rotten or weak decking boards
- Correct falls, so water drains away and doesn’t pond
- Insulation upgrades where needed (warm roof construction)
- New upstands, flashings and edge trims
- Outlets and guttering connected properly
- A full tidy-up, with all waste removed

Roofers Lincolnshire: Your Questions Answered
Which is better for a flat roof: EPDM or GRP?
Both are excellent when fitted properly. EPDM is flexible and suits simple roof shapes. GRP gives a hard, seamless finish that suits complex shapes and roofs that get occasional foot traffic. We’ll recommend what suits your roof.
How long does a new flat roof last?
That depends on the system and how well it is installed and maintained. Modern EPDM and GRP roofs, fitted on a sound deck with good falls, are designed to last for many years. We back all our work with a written guarantee.
Can you replace my flat roof with a pitched roof?
Often, yes, subject to the structure and any planning or building control requirements. We can advise on whether it’s practical for your building.
Do you install flat roofs on commercial buildings?
Yes. We carry out domestic and commercial flat roofing across Lincolnshire.
