What sets the cost of a flat roof
Size
A single garage is about 18m², a single-storey extension about 25m². Price per m² does the rest.
Covering
Torch-on felt is £80 to £110 per m², EPDM rubber £90 to £130 and GRP fibreglass £110 to £150.
The deck underneath
A soft or rotten deck has to be replaced before the new covering goes on. We check it and tell you first.
Roof lights and upstands
Each roof light, wall and edge takes detailing. That is where cheap flat roofs leak, so we price it properly.
Every flat roof from Swift Roofing includes
- The old covering stripped and taken away
- The deck checked and made good
- Your choice of felt, EPDM or GRP with proper edge trims and upstands
- A fixed written price and a workmanship guarantee

What Wisbech homeowners say
"Had quotes for our very tricky old Victorian cottage. Although all quotes were similar it was Luke's attitude and personality that got the job and we couldn't be happier, nothing was too much trouble and his workers are top drawer."
