Northolt has a lot of 1930s semis and post-war estates. Many of these homes now have flat-roofed extensions, garages and porches. Some estates also include post-war steel-framed houses. This guide covers what owners in Northolt should know about both. As local roofers covering Northolt, we see these problems often.
Flat roof options for Northolt homes
Most older flat roofs in Northolt use bitumen felt. It works well, but it usually starts to blister and crack as it ages. When a flat roof needs replacing, owners generally choose between three systems.
First, modern torch-on felt is a multi-layer system and a cost-effective upgrade. Second, EPDM is a single rubber membrane that suits simple roof shapes. Third, GRP fibreglass gives a hard, seamless finish that works well for small roofs and detailing. We will recommend the one that suits your roof, and explain why.
Common flat roof problems
Ponding water is the most common problem we see. When a deck sags or the falls are too shallow, water sits on the surface and wears it out faster. Also, edge trims and upstands against walls often fail before the main surface does. Blocked outlets are another frequent cause of leaks.
Steel-framed post-war houses
Some post-war houses, such as BISF (British Iron and Steel Federation) homes, use a steel frame. Their roofs often have a shallow pitch and profiled sheet coverings. If you own one of these homes, it is worth using a roofer who understands the structure. For example, fixings need care so they do not damage the frame or let water reach it. If you are not sure what type of house you have, we can tell you when we inspect.
Looking after a flat roof
A little maintenance goes a long way. Clear leaves from outlets and gutters each autumn. Then check for standing water a day after heavy rain. In addition, look at the edges and where the roof meets the house wall. Catching a small split early usually means a small repair.
