What's the best material for a flat roof?
It depends on your budget, the size of the roof, and how it’s used. GRP (fibreglass) is durable and low maintenance, EPDM rubber is flexible and long lasting, and felt is a cost effective option for smaller roofs. We’ll recommend the right system for your property during our survey.
How long does a flat roof last?
Most modern flat roofing systems last between [15 to 25 years] depending on the material and how well it’s maintained. We’ll advise on the expected lifespan of your chosen system.
Why is my flat roof leaking?
Common causes include membrane damage, pooling water, poor installation, or general wear over time. We’ll inspect the roof to identify the exact cause before recommending a fix.
Do flat roofs need more maintenance than pitched roofs?
They benefit from regular checks, particularly after storms or heavy rain, since pooling water and debris can cause issues if left unaddressed. We can advise on a maintenance routine to keep your flat roof in good condition.
How much does a flat roof installation or repair cost?
Cost depends on the size of the roof, the material used, and the extent of any repairs needed. We’ll give you a fixed, no obligation quote after a free survey.
Do you offer a guarantee on flat roofing work?
Yes, all our flat roofing installations and repairs come with a 1 year workmanship guarantee, alongside manufacturer warranties on materials used.
Do you offer emergency flat roof repairs?
Yes, we’re available round the clock for urgent jobs, including active leaks or storm damage.
