Roofcraft fits all three, so we can recommend the right system for your extension, garage or dormer rather than pushing a one-size-fits-all solution.

What our customers say
Frequently asked questions
Which flat roof lasts longest?
EPDM rubber and fibreglass typically outlast traditional felt, often 25 to 30 years or more. We'll talk you through the trade-offs of cost and lifespan for your project.
Can you insulate my flat roof?
Yes. We can build a warm-roof system with insulation above the deck, which improves comfort, cuts energy bills and meets current building regulations.
How long do flat roofs last?
It depends on the system: modern felt around 15 to 20 years, fibreglass 25 or more, and EPDM rubber 30 years or more. We'll recommend the best balance of cost and lifespan for your roof.
Why do flat roofs get a bad reputation?
Because older systems were thin and prone to splitting and ponding. Today's felt, fibreglass and rubber, installed with proper falls and detailing, are a completely different proposition.
Can you convert my flat roof to a pitched one?
In some cases, yes, a pitched conversion can improve drainage and looks. We'll assess whether it's practical for your structure, or recommend a high-performance flat system instead.
