Flat Roofs

Flat Roof Replacement

Felt flat roofs tend to fail the same way: the surface cracks in the sun, blisters lift, and the joints open until water sits on the deck and finds its way into the room below.

A replacement starts with the deck. Soft or rotten boards are replaced, then the roof is covered in torch-on felt, a single sheet of Rubbercover EPDM rubber or a Cure It GRP fibreglass system, finished with new trims at the edges and upstands.

Which one suits comes down to the size and outline of the roof, whether people will stand on it, and the details around roof lights, walls and gutters. You are given the reasons for the recommendation.

Why Choose Us

Why Choose Regent for Flat Roofs

Felt, rubber and fibreglass are all on offer, so the recommendation is about your roof, not about selling one product.

Three Systems, One Roofer

Felt, EPDM and GRP are all fitted, so you get the covering that suits the roof rather than the only one on offer.

Named Products

Rubbercover EPDM and Cure It GRP are the systems used, so you know what goes on your roof.

Deck Checked First

Soft boards are found and replaced first, so the new covering goes down on a sound base.

Sealed Edge Details

Trims, upstands and outlets are where flat roofs leak, so every one is sealed as part of the job.

FAQs

Flat Roof Questions

What Is the Difference Between EPDM & GRP?

EPDM is a synthetic rubber laid as a single sheet, so most extension and garage roofs end up with few or no joints, and it stays flexible as the building moves. GRP is fibreglass matting set in resin with a hard topcoat, giving a rigid, joint-free finish that is good for roofs with foot traffic or awkward details.

Can a New Flat Roof Go Over My Old Felt?

Usually not. Covering old felt hides any damp or rot in the deck underneath, so the old roof is stripped first and any soft boards are replaced before the new covering goes down.

Which Is Better for a Garage Roof?

EPDM is often the simpler choice for a plain rectangular garage roof, because it goes down as one sheet. GRP can suit garages that take foot traffic or that have more complicated edges. The inspection settles which fits best.

Can You Fit a Flat Roof Around a Roof Lantern?

Yes. Roof lights and lanterns are detailed into both EPDM and GRP roofs, with the upstand sealed so water cannot get in around the frame.

Why Is Water Pooling on My Flat Roof?

Standing water normally means the deck has dipped, or the roof was built with too little slope towards the gutter. When the roof is replaced, the falls are checked and corrected so water drains off.

Do You Repair Flat Roofs or Only Replace Them?

Both. Splits, blisters and open joints can often be repaired. If the covering is failing across the whole roof, replacing it in EPDM or GRP is usually the longer-lasting answer.
