Frequently Asked Questions
Can you repair a leaking flat roof?
Yes! We carry out all types of flat roof repairs—whether it’s a minor leak, cracks, or damaged felt. We’ll inspect the issue and advise whether a repair or replacement is best.
How long does a flat roof last?
It depends on the material. EPDM and GRP flat roofs can last 25–40 years with proper installation and maintenance, while felt roofs usually last around 10–15 years.
What’s the best material for a flat roof?
Each has its pros. EPDM is great for flexibility and longevity, GRP (fibreglass) offers a sleek, seamless finish, and felt is a more budget-friendly option. We’ll help you choose the best fit for your property and budget.
Do flat roofs require a lot of maintenance?
Flat roofs are generally low maintenance, but we recommend occasional checks for pooling water, blocked gutters, or visible damage—especially after heavy rain or storms.
