A good flat roof should be something you never have to think about. As experienced flat roof installers, we provide flat roofing and flat roof repairs for homes, extensions, and commercial buildings across Dorset, using materials and workmanship built to withstand coastal weather.
Flat roofs take a beating on the Dorset coast, and a small crack or patch of pooling water can quickly turn into a leak. Extreme Pro Roofing installs and repairs flat roofs for homes, extensions, garages, and commercial buildings, keeping your property dry in every season.
As flat roof specialists, we fit durable, watertight systems that resist cracking, standing water and wind damage. We recommend the right material for your property and budget. Every job starts with a free survey, so your quote covers exactly what your roof needs, and we fix the cause of leaks rather than patching over them.

We strip the old covering and fit a new flat roof on extensions, garages, porches and commercial buildings, built with the right falls so water drains away.
We fit seamless rubber roofing, a tough, low-maintenance choice for most flat roofs.
We lay strong, watertight GRP fibreglass roofs, ideal for smaller roofs and walkable areas.
We install and repair high-performance felt roofs, a budget-friendly option that still gives lasting protection.
Our flat roof repairs find the source of leaks and fix splits, blisters, cracked seams and failed edges, so you don’t pay for a full replacement you don’t need.
We clear blocked outlets and correct the problems that let water sit on your roof, so the covering lasts longer.

We check the covering, deck, and drainage, then take measurements. We explain your options and provide a clear written quote for the system that fits your roof and budget.

Most asked questions about flat roofing in Dorset.
It depends on the roof's size, material, insulation, and how easy it is to access, so prices vary widely. We give you a written quote after surveying your roof.
In a warm roof, the insulation sits on top of the deck; in a cold roof, it sits between the joists, with an air gap above. Warm roofs are usually preferred for new builds because they reduce the risk of condensation.
Only with care. Some roofs, such as GRP, can take occasional foot traffic, but felt and thin coverings can tear or crack, so ask your installer before stepping on it.
Sometimes, if the old roof is dry, firm and flat. If the deck is damaged or the insulation is wet, you have to remove the old roof first.
Usually only with planning permission, and the roof must be strong enough and have safety railings. A flat roof built for weatherproofing alone won't take the load.
Yes, flat roofs suit rooflights. They need to be fitted and sealed properly, or they become a common source of leaks.
Look for pooling water, blisters, cracks, splits, peeling edges, damp ceilings and leaks. Repeated repairs in the same area also mean the covering is failing.
