The service

What Flat Roofs Involves

Flat roofs sit on extensions, garages, dormers, porches and bay windows. They're never truly flat. A good one has a gentle fall that carries water to a gutter or outlet, a solid deck, the right insulation and a continuous waterproof covering.

You need a flat roof repair or replacement when you see standing water that stays for days after rain, blistering, cracking or splitting on the surface, soft spots underfoot, or damp patches on the ceiling below.

Most flat roof failures come down to the details: poor falls, a rotten deck, bad upstands where the roof meets a wall, or weak edges. We look at the whole roof, not just the top layer, so the new covering is laid on a sound, properly falling base.

If it's left

What Happens If You
Wait Another Winter

Ponding water

Water that sits on a flat roof finds every weakness and speeds up wear on the covering.

Rotten decking

Once water gets under the covering it soaks into the timber deck, which goes soft and has to be replaced.

Leaks into living space

Flat roofs are often over kitchens and living rooms, so leaks quickly damage ceilings, units and electrics.

Repeated patching costs

Patching a worn-out felt roof every winter often costs more over time than replacing it properly.

Common Mistakes
Homeowners Make

  • Re-covering over a soft or rotten deck
  • Ignoring the falls so water still ponds on the new roof
  • Skimping on upstands and edge details where most leaks start

In detail

Flat Roofs Across
Leicester & Blaby

Strip, inspect and rebuild

On a replacement we remove the old covering, inspect the deck and timbers, replace anything that has rotted and correct the falls before the new roof goes on.

Insulation and condensation

Where it suits the building, a flat roof replacement is a good chance to improve insulation. Getting the build-up right keeps the room below warmer and avoids condensation inside the roof.

Edges, upstands and outlets

We pay close attention to wall abutments, edge trims, gutters and outlets, because these are where flat roofs most often let water in.

Flat roof repairs

If the roof is basically sound, a targeted repair to a split, blister or failed joint may be all you need. We'll tell you honestly after the inspection which option gives you better value.

Homes and Rental Properties

Most of our flat roofs work is for homeowners, from terraces and semis to bungalows and detached houses. We also work for landlords who need a reliable fix and a clear record of what was done. Every job gets the same approach: a proper look at the roof, photos of what we find, and a fixed price before anything starts. If you're a landlord or a prospective buyer rather than the owner occupier, a £75 fee applies to the inspection; for homeowners it's free.

How to Choose a Roofer

Ask for a written, fixed price rather than a day rate, so the cost can't creep up once the scaffold is up. Ask to see photos of the problem before agreeing to anything. Check the guarantee, and get it in writing. Ask who will actually be on your roof. With us, it's Bobby Button and a team of four from start to finish, and the guarantee for your job is confirmed with your quote.

What to Expect on the Day

We turn up when we say we will and talk you through the plan before work starts. The roof is kept weathertight at the end of every working day, and we clear away old materials and debris as we go. When the job is finished we check it over, show you the completed work and tidy the site properly, so the only thing you notice is a roof that works.

Your Guarantee, Explained

Guarantee length depends on the type of work. A new roof is guaranteed for 25 years as standard. Work involving breathable membrane, including many leak repairs, is usually guaranteed for 10 years and in some cases 5. Cement work such as mortar and pointing is guaranteed for 5 years. Whatever your flat roofs involves, the exact guarantee is written into your quote, so you know where you stand before you say yes.

"Robert and his team done a fantastic job. I had a leak on my roof which they fixed very promptly, I also had them re-point my ridge tiles on my roof and it looks great. Very happy with the service, would definitely recommend."
