Flat roofs built to stay watertight

Flat roofs are common on London extensions, dormers and rear outriggers, and when they fail it’s usually at the edges, upstands and outlets. We pay particular attention to those details, so water drains away properly and can’t find a way in.

We install and repair modern flat roofing systems, including rubber (EPDM), fibreglass (GRP) and felt, and will recommend the right one for your roof’s size, use and budget. Replacements include checking the deck beneath and, where required, upgrading the insulation.

What’s included

  • Flat roof repairs and full replacements
  • Rubber (EPDM), fibreglass (GRP) and felt systems
  • New decking and insulation upgrades
  • Upstands for roof lanterns and skylights
  • Edge trims, drips and outlets
  • Ponding and drainage problems resolved

Frequently asked questions

How do I know if my flat roof needs replacing?

Signs include recurring leaks, blistering or cracking of the surface, standing water that doesn’t drain away, and a deck that feels soft underfoot. We’ll inspect it and tell you honestly whether a repair will do.

Which flat roof system is best?

It depends on the roof. Rubber (EPDM) is durable and flexible, fibreglass (GRP) gives a hard-wearing seamless finish, and modern felt systems are cost-effective. We’ll explain the pros and cons for your roof.

Can you fit a roof lantern on a flat roof?

Yes. We can form an insulated upstand and weather it into the new roof covering so the lantern stays watertight.
