Flat roofs are common across the UK, particularly on garages and extensions, largely due to their low cost. However, they are notorious for leaking, so you should be prepared to either patch or replace your roof every 15 years or so.
Maintenance costs shouldn’t be that expensive, and your roof should keep out the weather for years to come. But beware the all too common bodge jobs; these won’t only damage your bank balance, but your home too.
What is a Flat Roof?
Despite the name, flat roofs aren’t actually flat but pitched at a small angle. If they were completely level, water would pool on the surface of the felt, degrading the material and leading to leaks.
