Flat Roofing in Portsmouth

Flat roofs fail at the details: the falls, the edges, the upstands and the outlets. Get those right and a flat roof is low maintenance for years. Get them wrong and it ponds, then it leaks.

We install and repair flat roofs on garages, extensions, dormers and commercial buildings across Portsmouth. Every deck is prepared and checked for falls before anything is laid, because water that cannot run off will find a seam eventually.

You can choose felt, GRP fibreglass or EPDM rubber. Each suits a different job, and we will tell you which one fits yours and why, rather than fitting whatever we happen to carry.

Edges, upstands and outlets are detailed properly and finished cleanly, so the roof looks deliberate from the window above it as well as staying dry.

Common questions

Flat Roofing, answered

Which flat roof system is best?

It depends on the deck, the size, the access and how the roof is used. We explain the options for your roof rather than fitting one system to everything.

Why does my flat roof hold water?

Almost always because the falls are wrong or the outlet is blocked or set too high. Ponding water is what eventually finds a seam, so we correct the falls rather than covering over them.

Can you overlay my existing flat roof?

Sometimes, and sometimes it is a false economy. We will look at the deck condition and tell you which applies.
