However, flat roofs have a higher risk of leaking than sloped roofing, and if not dealt with promptly, even a minor leak can become a major problem very quickly. With a leak, your flat roof may allow water to enter your home through multiple points, this can seriously damage your property and the contents. Our leak detection experts will inspect the roof and find the source of any leaks quickly, helping you to avoid expensive repairs or replacements.

Roof Leak Detection Frequently Asked Questions
Why put gravel on a flat roof?
Gravel and pea shingle have two primary purposes on a flat roof; they provide a 'loading coat' and they afford UV protection. As ballast, the gravel will help anchor the material underneath and lower the risk of it being blown off in high winds.
Does walking on a flat roof damage it?
Flat Roofs A flat roof is less precarious than a pitched one, but you still run the risk of damaging the felt and potentially going through the membrane. You're less likely to cause damage on a warm day, and it's generally advisable to lay boards across it to walk on.
What do roofers use on flat roofs?
The most common ones include EPDM rubber, single-ply (TPO, PVC), modified bitumen, built-up roofs (BUR), and spray polyurethane foam. Many homeowners choose either EPDM or TPO. EPDM roofs are affordable and can reach a lifespan of 30+ years.
What is the most common defect in flat roof?
Leaks. Leaks are an all-too-common occurrence in buildings with flat roofs. This is mostly because flat roofs tend to lose their ability to effectively shed water if not properly maintained. Once moisture is unable to drain from the roof, it's just a matter of time before it finds its way into the building.
Should a flat roof hold any water?
Whilst brief and occasional ponding is acceptable on a flat roof, regular or long-lasting ponding could be an indication that there is an issue with the roof that needs to be addressed.
