Flat roofs don’t shout when they’re in trouble. They whisper. Miss the signs and you’re looking at serious damage—and a big bill. Here are five warnings your Reading flat roof needs attention now.
Puddles That Won’t Go Away
Rain’s stopped but there’s still water sitting on your roof two days later? That’s a problem. Flat roofs should drain within 48 hours. Standing water seeps into cracks and causes leaks. Left alone, it’ll damage the structure underneath.
Bubbles and Cracks
See blisters or cracks on the roof surface? That’s the material breaking down. Sun, rain, and frost take their toll over time. These are early warnings—fix them now before they turn into actual holes.
Damp Patches Inside
Notice brown stains on your ceiling? Mould in the corners? That’s water getting through your roof and into your home. By the time you see it inside, the problem’s already serious.
Dodgy Edges
The edges of flat roofs take the most punishment. If the flashing (the metal strips at the edges) is loose or damaged, water sneaks in at the joints. Check these regularly.
Your Roof’s Getting Old
Most flat roofs last 10-20 years depending on the material and how well they’re looked after. If yours is pushing 15 and showing wear, it might be time for a replacement rather than another patch-up job.
Don’t Wait
Small problems become big ones fast with flat roofs. Catch them early and you’ll save yourself money and hassle.
