Most garage roofs in West Glamorgan are old felt that's reached the end of its life — bubbled, cracked and leaking onto the cars, bikes or workshop kit below. Johnson's Roofing replaces garage roofs in EPDM rubber, GRP fibreglass or modern high-performance felt — typically in a single day, fully guaranteed, and with the gutter and trims sorted at the same time.
We start with a quick site visit and fixed quote — typically the promptly you call. On installation day we strip the old covering, inspect the timber deck (replacing any rotten boards), fit a new vapour control layer where needed, then install your chosen membrane with all-new trims and a fresh gutter. Old material is taken away and properly disposed of. Most single garages are completed in one day, doubles in two.
EPDM (rubber) is the most popular: one-piece membrane, no seams, long service life and excellent value. GRP (fibreglass) is seamless, slightly tougher underfoot and ideal if you ever walk on the roof. Modern torch-on felt is the cheapest option and still gives 15-20 years. We'll recommend honestly based on your garage.
Most single garages are completed in one day. Double garages or jobs that need new timber decking take two days. We give you a firm date and stick to it.

Yes, and we usually recommend it — the old gutter is almost always at the end of its life when the felt has failed. Doing both together is significantly cheaper than two separate visits.
