Flat Roofers Bristol

Bristol has a lot of flat roofs: rear extensions, garages, dormers and the odd porch or bay. When one starts to leak, most homeowners want two things. They want to know who can fix it, and whether it needs patching or replacing.
At Bristol Heritage Roofing And Sons, we repair, maintain and replace flat roofs on Bristol homes, including felt roofing, removing old coverings and fitting new EPDM rubber or fibreglass roofs. Our team brings over 25 years of roofing expertise to every job. We look at your roof first, then tell you plainly whether a repair will do or whether a new covering makes more sense.
Flat roofing looks simple, but water finds the weakest spot quickly. Catch a leak early and the fix tends to be small. Leave it, and the damp spreads into timbers, plaster and insulation below.
What Flat Roof Work Does Bristol Heritage Roofing And Sons Offer?
We cover the full life of a residential flat roof. That means fixing leaks, keeping a roof in good order, stripping worn coverings and fitting new ones on extensions, garages and other small roofs. Our work is aimed at homes, and we keep our own services clear from those of other firms with similar names.
Flat Roof Repairs, Maintenance and Removal
Most calls we get start with a leak or a stain on a ceiling. Our flat roof services cover expert installation and maintenance, and repairs are part of that day-to-day work.
A typical repair visit looks like this:
- We find where the water is getting in, which is not always right above the stain.
- We check the seams, edges, outlets and flashings (the strips that seal the roof to a wall).
- We repair the damaged area or advise you if the covering has worn out.
Maintenance is the quieter side of the job. Clearing debris, checking outlets and spotting small cracks before winter all help a roof last longer.
When a covering is past saving, we remove it. Stripping back lets us see the deck (the boards under the covering). Soft or rotten boards need sorting before anything new goes on top.
New Flat Roofs for Extensions, Garages and Small Roofs
For new work, we fit felt, EPDM rubber and fibreglass coverings. These suit the kind of flat roofs found on Bristol homes:
- Single-storey rear extensions
- Garages, attached or detached
- Dormers and porches
- Bay roofs and small outbuildings
Each roof is different in size, access and how water drains off it. We talk you through the options that fit your roof and budget. We also handle professional gutter repairs, which matters on a flat roof because water has to leave the surface somewhere.

Should You Repair or Replace a Leaking Flat Roof?
A single leak on a roof in decent shape can usually be repaired. Widespread wear, soft decking or repeat leaks point towards replacement. An inspection is the best way to tell which camp your roof falls into.
What Do Leaks and Worn Coverings Tell You?
Signs of trouble show up both inside and on the roof. Inside, look for:
- Brown stains or bubbling paint on the ceiling
- A damp or musty smell in the room below
- Mould in corners near the roof
On the roof itself, look for cracks, blisters, splits at the seams, and pools of water that sit for days after rain. Blocked guttering and outlets also cause trouble, because water backs up onto the roof.
Leaving water ingress unfixed is where costs climb. Wet boards rot, insulation stops working and plaster can come down. Put a bucket under any drip, keep off the roof in wet weather, and get it looked at soon.
When Might a Repair Be Enough?
A flat roof repair makes sense when the problem is small and in one place. Common examples:
- A split at one seam
- A lifted edge or a failed flashing against a wall
- Damage from a fallen branch
- A blocked outlet causing water to pond
If the rest of the covering is sound and the deck underneath is dry and firm, a good repair buys you years. We will tell you straight if we think a patch will hold.
When Is Replacement the Better Option?
Replacement is the better choice when the covering has worn out across the roof. Think many cracks, lots of blisters, a surface that has gone brittle, or boards that feel spongy underfoot.
Repeat leaks are another sign. Paying for fix after fix adds up. As a rough benchmark, a standard flat roof replacement in the UK is commonly quoted at around £2,800 to £7,500, averaging about £75 per m². Your own price depends on size, access and the covering you choose.
A new roof also lets us fix drainage, replace rotten boards and choose a better covering. Plenty of homeowners see that as money well spent.

Which Flat Roof Covering Fits Your Project?
For most small Bristol roofs, the choice comes down to felt, EPDM rubber or fibreglass. Each works well when fitted properly. The right one depends on your roof's size, shape, use and your budget.
| Covering | What it is | Good for |
|---|---|---|
| Felt | Layers of bitumen-based sheet | Budget-minded repairs and re-roofs |
| EPDM rubber | One large sheet of rubber membrane | Simple shapes like garages and extensions |
| Fibreglass (GRP) | Resin and glass matting set hard | Roofs with details or light foot traffic |
Felt Roofing
Felt is the covering many older Bristol extensions and garages already have. Modern felt is tougher than the old single-layer stuff you might remember. It is laid in layers to build up a waterproof finish.
Felt suits people who want a proven, sensible option. It is also easy to repair in patches, which helps down the line.
EPDM Rubber for Small Residential Roofs
EPDM is a synthetic rubber sheet. On a small roof, it can often go on in one piece, so there are few or no joins for water to get through.
It works well on garages and plain rectangular extensions. It stays flexible in cold weather and copes with the roof moving slightly as it warms and cools.
Fibreglass (GRP) Roofing
GRP stands for glass reinforced plastic. Resin and glass matting are laid over the deck and set into a hard, seamless shell.
It suits roofs with awkward corners, upstands or rooflights, because it can be shaped around them. It also gives a neat finish that some homeowners like on a visible extension.
How to Get a Free Flat Roof Inspection
The easiest way to start is to contact us through our website and tell us what is going on with your roof. We cover homes in Bristol and offer free, no-obligation quotations for our flat roofing services.
Our quotes are free. When you book a visit, ask us whether the inspection itself is free for your job, so you know where you stand before we arrive.
To help us help you, have a few details ready:
- Where the roof is (extension, garage, dormer and so on)
- Roughly how big it is
- What you have noticed, such as stains, drips or pooling water
- How old the roof is, if you know
- A couple of photos taken safely from the ground or a window
Until we visit, catch drips in a bucket, move anything valuable out of the way and stay off the roof. Once we have seen it, we will explain whether a repair or a new covering fits, and give you a clear written price.
