Flat Roofing Surrey | GRP, EPDM & Felt Systems

Q: Which flat roofing system is best for a Surrey home?

The best flat roofing system depends on the roof shape, detailing, intended use and budget. We recommend the system that best suits the individual project.

Q: How long should a properly installed flat roof last?

A properly installed flat roof should last for many years when the waterproofing and detailing are carried out correctly.

Q: Can you repair a leaking flat roof instead of replacing it?

Yes, when the roof is still fundamentally sound. If repair is sensible we will say so, and if replacement is better value we will explain why.

Flat Roofing in Surrey - Common Issues

Flat roofs on Surrey properties are particularly susceptible to ponding water, UV degradation and poor drainage. Regular inspection and prompt repair prevents minor issues from becoming expensive failures.

Avoid DIY Flat Roof RepairsIncorrect repairs to flat roofs often void manufacturer warranties and can cause more damage than the original issue. Always use a qualified specialist.

Flat Roofing FAQs

If you are comparing systems or deciding whether a flat roof needs repair or replacement, these are the questions we most often answer.

Which flat roofing system is best for a Surrey home?+

There is no one-size-fits-all answer. GRP is excellent for many domestic roofs and dormers, EPDM works well on larger simple areas, and felt still has a place on the right project. We recommend the system that best suits the roof shape, usage, detailing and budget.

How long should a properly installed flat roof last?+

A good flat roof should last for many years when it is installed correctly and detailed properly around edges, outlets, lanterns and upstands. Lifespan varies by system, but our aim is always to install something dependable rather than a short-term fix.

Can you repair a leaking flat roof instead of replacing it?+

Yes, when the roof is still fundamentally sound. We inspect the condition of the deck, the membrane and the details before advising. If a repair is the sensible option, we will say so. If the roof has reached the point where replacement is better value, we will explain that too.

Do you install flat roofs with skylights or lantern openings?+

Yes. We regularly build and waterproof flat roofs that include roof lanterns, skylights and raised upstands. The detailing around those features is critical, and it is an area we pay close attention to.
