How long does a flat roof last?

Most flat roofs last around 20 to 30 years. This depends on the material used and how well the roof has been looked after. EPDM rubber roofing and GRP fibreglass roofing tend to outlast older felt roofs, especially with regular checks.

Which flat roofing system is best?

It depends on your building and your budget. GRP fibreglass gives a strong surface with no seams. EPDM rubber is flexible and copes well with small building movements. Single ply roofing works well on larger business roofs. We can talk through which one fits your needs during your free inspection.

Can a flat roof be repaired instead of replaced?

Often, yes. Many problems, like a small split or a local leak, can be fixed without replacing the whole roof. We check this first. This way, you only pay for a full replacement if the roof really needs one.

How much does flat roofing in Reading cost?

The cost depends on the size of the roof, the material used, and how much repair work is needed. We give you a free, no-obligation quote. This means you know the price before any work starts, with no hidden extras added later.
