Flat roofing covers extensions, rear additions, bay window tops, porches, garages, and flat-roof bungalows — all common across Lowestoft's housing stock. A failed flat roof, whether it's an old felt system that's split or a poorly installed replacement that's pooling water, is one of the fastest ways to cause serious damage inside a property.
For new flat roofs and full replacements, we install GRP fibreglass and EPDM rubber membrane systems. GRP (fibreglass) is our most popular option for domestic extensions — it's seamless, highly durable, and carries a 25-year product guarantee. EPDM is a single-ply rubber membrane that works well on larger areas and is particularly resistant to the UV exposure and temperature fluctuations you get in a coastal climate. For straightforward repairs to existing torch-on felt systems we can patch and reinstate without necessarily replacing the whole roof area.
Avoiding a flat roof specialist and going with a general builder who lays standard felt is a false economy. Poor drainage design, inadequate upstands at abutments, and incorrect solar-reflective finishing all cause premature failure. A flat roof that's properly detailed should not need attention for 20–30 years.
We survey the existing structure, check the decking and joists for moisture damage, and improve the fall where possible before any new covering goes down. Most domestic flat roof replacements on Lowestoft extensions take one to two days. Larger garage or commercial roofs take two to four days. All work is covered by our workmanship guarantee, and GRP and EPDM systems come with manufacturer product warranties.
Flat roof replacement in Lowestoft typically costs £70–£110 per square metre installed for GRP fibreglass, and £60–£90 per square metre for EPDM rubber.
