What helps a flat roof last better

Falls formed correctly

Water needs a route off the roof, not a string of puddles after every shower.

Deck condition checked

A sound surface underneath matters as much as the finish you can see on top.

Details treated seriously

Edges, outlets and penetrations are handled carefully because leaks often start there.

A flat roof needs more than a new covering

A good flat roof starts underneath the top layer. The deck has to be sound, the build-up has to suit the structure, falls need to move water the right way, and the outlets, upstands and edges all have to be detailed properly. We install flat roofs on extensions, garages, commercial areas and other low-pitched structures where a rushed job soon shows itself in standing water or damp edges. With Roofwise Roofing Services, the specification is built around how the roof drains and how the whole area is used.

Built to suit the structure underneath

Before installation, we look at the supporting deck, whether failed material needs stripping off, and whether a warm or cold roof build-up is more appropriate. We also check penetrations and outlets because the weak spot on a flat roof is often where one element meets another, not the open area in the middle.
Choosing Roofwise Roofing Services means the roof is prepared, fitted and checked as a complete weatherproof surface, not just recovered and hoped for.

Frequently asked questions

What is the difference between a warm and cold flat roof?

The difference is mainly where the insulation sits within the build-up and how ventilation is handled. The right choice depends on the structure and the planned specification. We explain the options before work starts so the build makes sense for the roof, not just the quote.

Can you install a flat roof on an extension or garage?

Yes. Flat roof installation suits extensions, garages and other low-pitched areas, as well as commercial roof sections. We inspect the deck, drainage and edges first so the finished roof is properly supported and weatherproof from the start.

What if the existing flat roof deck is damaged?

If the deck or supporting layers are unsound, that needs dealing with before the new covering goes down. We assess the condition during the survey and explain what preparation or repair is needed so the new roof is not sitting on a weak base.
