Felt flat roof systems
Felt roofing is built up in layers bonded together, creating a continuous waterproof covering. Legacy Roofing works mainly with these traditional felt systems for both new roofs and repairs.

Flat Roofing for Extensions, Garages and Commercial Buildings
What the service covers
New felt flat roof installations, full replacements of failed flat roofs, and repairs to splits, blisters and leaking edges. Legacy Roofing works mainly with traditional felt systems.
Who it's for
Homeowners with flat-roofed extensions, garages, porches, bay windows and dormers, plus landlords and businesses with flat-roofed commercial units.
When it's needed
When water pools on the surface, the felt has blistered or cracked, edges are lifting, or you're getting drips inside. A new extension will also need a flat roof fitted properly from the start.
Why professional help matters
Flat roofs depend on correct falls, solid decking and properly sealed edges and upstands. Get any of those wrong and water sits on the roof until it finds a way in. Stephen brings 10 years' experience to every detail.
What a Failing Flat Roof Costs You
Flat roofs don't shed water as quickly as pitched roofs, so small faults turn into leaks faster.
Ponding water
Water left sitting on a flat roof works its way into any weakness and speeds up wear on the felt.
Rotten decking
Once water gets under the felt, the timber deck soaks it up and rots, making the whole roof soft underfoot.
Ceiling damage below
Extensions often have kitchens or living rooms under the flat roof, so leaks land in the rooms you use most.
Damp walls
Failed upstands and edge details let water run down into walls where they meet the house.
Common mistakes to avoid
Patching over blisters
Covering blisters without dealing with trapped moisture lets the problem spread under the patch.
Ignoring the deck
New felt laid on a soft, rotten deck will fail early.
Forgetting the edges
Most flat roof leaks start at edges, upstands and outlets, not in the middle.

Felt Flat Roofing Explained
A good flat roof is about more than the top layer. Here's what goes into one built to last.
Falls and drainage
A flat roof is never truly flat. It needs a gentle fall so water runs to the gutter or outlet. Where a roof holds water, the fall is assessed and corrected during replacement.
Decking
The deck is the structural board the felt is laid on. A firm, dry deck is essential. Boards that are soft, sagging or rotten are replaced before new felt goes down.
Edges, upstands and outlets
Where the roof meets the house wall, the felt is turned up and sealed. At the edges, drip details direct water into the gutter. These details are where most flat roof leaks begin.
Common flat roof situations
Single and two-storey extensions, garages, porches, bay roofs, dormers and commercial units. Each has its own access and edge details, and each is assessed on site.
Residential vs commercial flat roofs
Commercial flat roofs tend to be larger, with more outlets and penetrations to detail. Domestic flat roofs often sit close to living spaces, so protecting the rooms below during work matters most.

Choosing a Roofer for Flat Roofs in Berkshire
When you are looking for someone to handle flat roofs on your property, the biggest risk is not the materials. It is not knowing who will actually turn up, whether they will do what they said, and who you can call if something is not right afterwards. Legacy Roofing removes that uncertainty by keeping everything with one person. Stephen Farrow inspects your roof, explains what he has found, gives you the price, does the work and stands behind it.
One roofer, start to finish
Many roofing firms send a salesperson to quote and a different crew to do the job. Details get lost between the two, and you end up repeating yourself. Because Legacy Roofing is a solo business, the conversation you have at the inspection is the same one the roofer on your roof remembers. If you have a question halfway through, you ask the person doing the work.
Straight answers before you spend anything
Every job starts with a free, no-obligation roof inspection. Stephen will tell you plainly what is wrong, what it needs, and what it does not need. If a smaller repair will solve the problem, that is what he will recommend. You will know what is included in the price before any work begins, so there are no awkward surprises at the end.
Experience you can check
Stephen has 10 years of hands-on roofing experience on domestic and commercial properties. Legacy Roofing holds £1 million public liability insurance, every new roof carries a 10-year guarantee, and repair guarantees are explained clearly for the specific work carried out. If water is coming in, a 24-hour emergency call-out service means you are not left waiting until Monday.
What to expect on the day
Stephen arrives when he says he will. Before starting, he walks you through the plan again so you know which parts of the roof he will be working on and roughly how long each stage should take. Access is set up safely, and anything that could be affected around the property, such as paths, plants or parked cars, is considered before work begins. While the job is under way, you can ask questions at any point, and if something unexpected turns up once the roof is opened, he will show you and talk it through before going any further. Nothing extra is added without your agreement.
When the work is finished, Stephen checks it over, clears away old materials and debris, and explains what has been done and which guarantee applies. You are left with a roof that has been looked after properly, a clear record of the work, and the direct number of the roofer who did it, should you ever need him again.
