Flat Roofs in Stockport

Sometimes, but we usually recommend stripping the old felt. Laying over it hides any rot in the deck underneath and can trap moisture. Stripping back lets us check and replace damaged boards so the new roof has a solid base. We'll explain what we find and why.

Sagging usually means the deck boards or joists have weakened, often because water has been getting in for some time. We replace the damaged decking, and where possible add firring strips to create a proper fall so water runs off. Then the new covering goes on top.

The flat roof covering is turned up the wall as an upstand, then covered with a flashing, usually lead or a suitable trim, chased into the brickwork. This junction is where most extension leaks start, so we take care to get it right. A poor seal here will leak however good the rest of the roof is.

GRP is often preferred on dormers because it's rigid and forms neat edges and corners, which suits roofs with lots of detailing. EPDM works well on dormers too. The choice depends on the shape of the roof, access, and personal preference. We'll recommend what suits your dormer best.

Yes. Small felt roofs over bays and porches often crack or lift where they meet the wall. We can repair them or re-cover them in EPDM, GRP or lead, depending on the house and your budget. On period properties, lead is often the better-looking option.
