Flat Roofers Buckingham
The Buckingham Flat Roofing Team You Can Rely On
Flat roofs have a reputation for causing problems — and in many cases, that reputation is deserved. Not because flat roofing is inherently unreliable, but because it's been installed badly so many times. Old-style torch-on felt laid over a poorly prepared deck, inadequate drainage falls, edge details cut short to save time — these are the reasons flat roofs leak, blister, and fail within a decade. When a flat roof is designed and installed correctly, using the right system for the application, it should last 25 to 50 years with minimal maintenance.
Supreme Roofing installs and repairs flat roofs across Buckinghamshire for homeowners, landlords, and commercial property owners. Whether you need a leaking garage roof sorted, a new flat roof on an extension, or a full replacement on a bungalow, our team carries out all flat roofing work to a proper standard — correct falls, correct edge detailing, correct membrane specification — because it's the details that determine whether a flat roof performs or fails.
We'll survey your flat roof, advise you honestly on the best system for your property and situation, and provide a clear written quote before any work begins.
5 Star Rated Roofers In Your Area
Had Supreme Roofing replace our roof after storm damage last winter. Brilliant service from start to finish — fair price, tidy team, and excellent workmanship. Highly recommended
Called them out for a chimney repair that two other roofers had ignored. They spotted the problem straight away, explained everything clearly, and had it sorted within a few days.
Got our fascias, soffits and guttering replaced, the difference is incredible. Turned up on time and the finish is perfect. Will definitely be using Supreme Roofing again.

Warm roof vs cold roof — why it matters on extensions and habitable spaces
If your flat roof sits above a habitable room — a bedroom extension, a kitchen extension, a converted outbuilding — the construction of the roof matters beyond just waterproofing.
A cold roof construction, where insulation sits between the joists below the deck, is prone to condensation issues and performs poorly thermally compared to a warm roof, where insulation sits above the structural deck beneath the waterproofing membrane.
On garages and outbuildings used purely for storage, a cold roof is often perfectly adequate. On any space that's heated or occupied, a warm roof construction is strongly recommended — it performs better thermally, eliminates the condensation risk, and results in a noticeably more comfortable space year-round.
We'll advise you on the right construction for your specific project when we carry out the survey.
Flat Roofing Frequently Asked Questions
It depends on the size of the roof, the application, and your budget. EPDM rubber is our most recommended system for most residential flat roofs — it's durable, flexible, seamless on smaller roofs, and carries a lifespan of 40 to 50 years when installed correctly. GRP fibreglass is an excellent choice where a hard, rigid surface is needed and is particularly suited to roofs with complex detailing. Traditional felt is a cost-effective option for smaller outbuildings and budget-conscious projects, though it carries a shorter lifespan than the other two. We'll advise you on the right choice for your specific situation when we survey the job.
It depends entirely on the system. Traditional felt flat roofs typically last 10 to 15 years. GRP fibreglass roofs, when properly installed, last 25 to 30 years or more. EPDM rubber roofs have a proven lifespan of 40 to 50 years and in many cases longer. The single biggest factor determining how long any flat roof lasts is the quality of the installation — specifically the preparation of the deck, the falls, and the edge and upstand detailing. A poorly installed EPDM roof will fail long before a well-installed felt roof.
It depends on the age of the roof, the system, and the extent of the damage. A relatively new EPDM or GRP roof with an isolated failure at a detail or seam is usually repairable. An old felt roof that's blistering, cracking across its surface, or leaking in multiple places is almost always past the point where repair is cost-effective. One of the most common mistakes homeowners make is spending money on repeated repairs to an old felt roof that simply needs replacing. We'll survey your roof and give you an honest assessment of whether a repair will solve the problem long-term or whether replacement is the better investment.
The most common causes are failed or poorly detailed upstands where the membrane meets a vertical surface, poor drainage falls that allow water to pond and sit on the surface, cracked or split felt on ageing roofs, and edge detail failures where the membrane has pulled away or been inadequately fixed. On older properties, failed or missing lead flashing where the flat roof meets a parapet or wall is also a frequent culprit. Identifying the actual source of a flat roof leak requires experience — water travels, and the point of ingress is rarely directly above the damp patch on your ceiling.
Yes, though modern systems require very little. EPDM and GRP roofs should be inspected annually — clearing any debris that's collecting in outlets or gutters, checking that upstands and edge details are intact, and making sure drainage is flowing freely. Keeping a flat roof clean and clear of debris significantly extends its lifespan and reduces the likelihood of blockages causing ponding.
