Hayes has a large amount of post-war housing, and some estates include steel-framed homes such as BISF houses. These homes look ordinary from the street, but their roofs need a slightly different approach. This guide explains what BISF owners should know. As local roofers covering Hayes, we see these problems often.

What is a BISF house?
BISF stands for British Iron and Steel Federation. After the Second World War, BISF houses used a steel frame to speed up building. Many have a shallow-pitched roof with profiled sheet coverings, although some now have tiled roofs after re-roofing.
Common BISF roof issues
Older sheet coverings can crack or become brittle with age. Also, fixings can loosen, and the joints between sheets can let water in. Because the house has a steel frame, it is important to stop leaks early. Otherwise, damp can reach parts of the structure that owners never see.
Repair or re-roof?
Small problems often only need a repair. However, many owners eventually choose to replace the old covering. The right option depends on the roof structure, so a proper inspection comes first. We explain what we find and give you a written, itemised quote.
If your home is a non-standard construction, it is also worth checking with your mortgage lender or insurer before major work.
Other roofs in Hayes
Of course, most Hayes homes are traditional brick houses. Flat-roofed garages and extensions are very common here. So we also repair and replace flat roofs using modern felt, EPDM and GRP systems.
When to call roofers in Hayes
Call us if you notice damp patches on ceilings, slipped tiles or overflowing gutters. Also get in touch after a storm if anything on the roof looks out of place. Before any major changes, it is also worth checking the Planning Portal guidance on roof work.
