Flat Roofing and EPDM in Retford for Garages and Extensions
In a market town like Retford, flat roofs are usually found in the practical parts of a property: the garage at the side, the single-storey extension at the back, the lean-to over a utility room. They do an unglamorous job and tend to be ignored until water comes through. Smaller outbuildings and lean-tos on the edges of town need the same attention as bigger roofs, though they are often simpler jobs.




We cover Retford and the surrounding villages for flat roofing using EPDM rubber, felt and GRP fibreglass, on both repairs and new roofs. Which suits a given building depends on its size, shape, access and the way it drains.
Systems and where they suit
EPDM is a flexible synthetic rubber membrane, often used on larger or simpler roofs where it can be laid with few seams. GRP gives a continuous waterproof fibreglass finish that suits smaller roofs and awkward outlines, and felt remains an established option with repairs carried out in a way that suits the product. The junction against a brick wall is a classic place for a flat roof to fail, so upstands and flashings are checked whatever the covering.
Flat roof work may need building regulations approval, so check with your local council.

Old garages and outbuildings
Older garages in the area may have cement-sheet roofs, which can contain asbestos. That needs identifying before anyone works on them, and it affects how a replacement is planned. Outlets and gutters at the edge of a flat roof should be clear, since standing water shortens the life of any membrane.
If a flat roof is dripping or looks tired, call or WhatsApp with photos of the roof and any ceiling stains, and we will talk through repair or replacement and quote.

Flat Roofing and EPDM in Retford: common questions
My garage roof leaks at the edge. Is that fixable?
Often it is, as edges and upstands are common failure points and can sometimes be resealed or re-dressed. If the covering is worn throughout, replacement is the better route. The age of the covering and the number of earlier repairs would affect the decision, and we would explain our reasoning.
Which lasts longer, EPDM or felt?
It depends on the product, how it is laid and the condition of the deck beneath. We would describe the pros and cons for your roof rather than quote a general rule. The condition of the deck beneath and the quality of the detailing matter at least as much as the material.
