Most flat roof leaks start at the edges: the upstand against the wall, the drip trim at the gutter, or the outlet where water is meant to leave. Water that sits in a dip, called ponding, finds every weak lap in the covering.

We check the covering and the deck under it. Where the deck is sound, a repair or overlay can be the right answer. Where it is soft or rotten, it comes up and a new deck goes down with the right fall, before the new covering goes on.

Signs you need flat roofs

  • Water sitting on the roof days after rain
  • Blisters, cracks or splits in the felt
  • Damp patches on the ceiling below
  • Moss growing along the edges
  • Soft or spongy feel underfoot
  • Leaks where the roof meets the house wall

What is included

  • Old covering and rotten decking removed
  • New deck laid with a proper fall to the outlet
  • Torch-on felt, GRP fibreglass or EPDM rubber
  • Upstands, flashings and drip trims renewed
  • New fascia and gutter where needed
  • Waste cleared, site left tidy

Flat roofs questions

Felt, GRP or rubber: which is best?

All three work well when they are laid properly. Felt is the most familiar, GRP gives a hard, seamless finish, and EPDM rubber suits simple shapes. We explain the options for your roof at the survey.

Can my flat roof be repaired rather than replaced?

Often, if the deck underneath is dry and solid. We check it and price the repair and, where it makes sense, the replacement, so you can choose.

How long does a flat roof replacement take?

A garage or small extension roof is one to two days on site.

Is a new flat roof guaranteed?

Yes, with our 10-year guarantee, written on your quote.
