Extensions and garage roofs across South Yorkshire are mostly flat or low-pitch, and they fail differently to a pitched roof, usually at the joints and upstands rather than the tiles. We fit GRP fibreglass roofing for durability, or felt where it suits the budget better, and we’ll advise honestly on which one your roof actually needs.

GRP has a longer expected lifespan and no seams to fail, which matters on a roof that gets less attention than the main one over the years. Felt is cheaper up front and still does the job well on smaller structures like sheds and single garages where the extra cost of GRP is harder to justify.

Ponding water, cracked seams or a roof that’s visibly sagging in the middle are the signs worth acting on before a small repair turns into a full replacement. We’ll assess it and give you a straight answer either way.

From £900 for a standard garage roof, more for larger extensions or dormers. Free, no-obligation quotes with no pressure to upgrade beyond what the job needs.
