Modern felt roofing remains one of the most widely used flat roofing systems for garages, extensions, sheds, outbuildings and commercial properties.
Flat Roofing South Wales provides professional felt roof installation, replacement and repair services throughout South Wales.
Flat roofing felt has developed considerably from the basic systems traditionally associated with garden sheds and older garage roofs. Modern high-performance felt roofing systems provide multiple layers of waterproof protection and can create a strong, dependable flat roof when correctly installed.
Whether you have an older felt roof that has begun leaking or require a completely new roofing system, we can assess the roof and recommend the most practical solution.




Older felt roofs can eventually deteriorate through weather exposure and general ageing. Common problems include:
Good preparation and professional installation are particularly important because roof edges, joints, outlets and flashing must all be properly sealed.
We can inspect the roof and locate the likely source of any problem before recommending the best solution.
Continually patching a badly deteriorated felt roof can become a false economy.
Where the existing covering has reached the end of its practical life, complete replacement may provide better long-term value. The existing covering can be removed and the roof deck inspected before the new roofing system is installed.
Any damaged or unsuitable decking discovered during the work can be identified before the new waterproof surface is completed.
Our felt roofing services cover garages, extensions, porches, sheds, workshops, outbuildings and other domestic or commercial flat roofs.
We undertake everything from individual repairs to complete replacement roofs.
If your felt roof is cracked, bubbling, leaking or simply looking past its best, arrange an inspection before water causes more extensive damage.
