Flat roof repairs and replacement in Brighton and across the south coast

A flat roof over an extension, garage, porch or dormer does a lot of work in a wet climate. We repair and replace flat roofs with modern systems, and we will tell you which one your roof needs.

Repair or replace?

Many flat roof leaks start at a small weak point: a split in the covering, a failed joint, or a poorly sealed edge where the roof meets a wall. If the rest of the roof is in good condition, a targeted repair can be the sensible answer. If the covering is widespread cracked, blistered or holding water, or the deck underneath is soft, replacement is usually the better route.

We will find out which situation you are in and explain it in plain English before any work starts.

Systems we fit

We work with single ply membranes, felt systems and hot melt. Each has its place, depending on the shape of the roof, the details around it and how it is used. When we replace a flat roof we can also lay new decking and insulation so that the new roof is built on a sound base.

Flat roofs are common on rear extensions, garages, bay windows and dormers on the homes we work on in Brighton, Hove, Worthing, Portsmouth and the other towns along the coast, and we have repaired and replaced them in all of those places.

Water and ponding

Puddles that sit on a flat roof for days are a warning sign. Standing water puts constant pressure on the covering and its joints, and it can shorten the life of the roof. If you can see ponding, or you have stains on the ceiling below, get in touch and we will take a look.

Pitch and flat roof replacement

“We cannot praise and recommend this team highly enough. We were in need of pitch and flat roof removal and replacement (mid terrace) and saw this team working on a nearby house. We were impressed by their skill and craftsmanship and before we could approach them they knocked our door, having seen the state of our roof and offered their services. Work was assessed and an instant quote given. The water damage which had already occurred was even worse than we anticipated. We booked the firm and they were able to start within days. Their hard work, speed, and quality craftsmanship exceeded our expectations. They genuinely worked as a team and were all pleasant, polite and cheerful. Always punctual in arrival and clearing and removing rubbish. Work was completed within the time limit given and we no longer fear the bad weather. Price was competitive and they were worth every penny.”

Frequently asked questions

Can a leaking flat roof be repaired, or does it need replacing?

Both happen. A single failed joint or flashing can often be repaired. A tired covering with several problems, or damaged decking, usually means replacement. We will check and tell you which.

Which flat roof systems do you use?

Single ply membrane, felt and hot melt systems. We will recommend the one that suits your roof.

Do you replace the decking and insulation as well?

Yes, we can lay new decking and insulation as part of a flat roof replacement.

Do you do garage roofs?

Yes. Garage and outbuilding roofs, flat or pitched, are part of what we do.
