Flat Roofing in Mansfield: EPDM and GRP for Garages and Extensions
Look across a Mansfield estate and you will spot the flat roofs: a garage beside a post-war semi, a porch over a front door, a kitchen extension at the back of an older terrace. They are usually the smallest part of the roof and the first to give trouble. Evans Roofing Services covers Mansfield and nearby towns for flat roof installation and repair.




Most flat roofs we are asked about use one of three systems. EPDM is a flexible rubber membrane, felt is the traditional layered covering, and GRP is a continuous fibreglass finish. Choosing between them depends on the shape of the roof, the structure beneath it and how it will be used. Many Mansfield flat roofs have been patched over time, and the layers of old repairs can hide the real fault.
From a leaking garage to a new extension roof
A flat roof leak may come from a failed joint, a puncture, a tired edge or a poorly sealed flashing. We assess each before choosing a compatible repair, and if the covering has worn out or the deck has gone soft, a new roof is usually more sensible. On a rear extension, the junction with the main house wall is often the culprit, so the flashing and upstand are checked as carefully as the membrane.
Older garages sometimes have cement-sheet roofs that may contain asbestos. That needs identifying before any work is done, so tell us about the age and type of roof when you get in touch.
What decides how long a flat roof lasts
Good materials matter, but so do the details around them. Many flat roof problems begin where the membrane meets something else. When a roof is renewed, it is also the moment to improve edges and drainage that were poor the first time round.
- Flashings and upstands against walls
- Perimeter trims and drip edges
- Outlets, gutters and the fall to them
- Penetrations such as vents and rooflights
- Building regulations approval, which may apply to some work, so check with your local council

Flat Roofing and EPDM in Mansfield: common questions
My garage roof in Mansfield is sagging. Can it be recovered?
It depends on the deck beneath. If the boards are sound a new covering can go over them, but a sagging roof often points to damp or rotten timber that has to be dealt with first. Ponding, bubbling and a spongy feel underfoot all point to a failing deck or covering.
Is EPDM a good choice for a porch roof?
It is commonly used on small flat roofs because the membrane can be laid with few seams. A look at the shape and the edges tells us whether it suits yours. Send photos of the roof, the edges and the ceiling inside.
