What homeowners ask before the work starts
How much does a flat roof replacement cost?
A standard single-storey extension GRP flat roof typically starts at around £800 to £1,200 for smaller areas. They provide a free written quote for the work.
Do I need planning permission to replace a flat roof?
Generally not for replacing an existing flat roof with similar materials, as this usually falls under permitted development. New structures are subject to the rules applying to the structure.
How long does their GRP flat roofing last?
A properly installed GRP flat roof typically lasts 25 to 30 years, with periodic cleaning and protection from sharp impacts recommended.
Can they match existing roof tiles for a repair?
In most cases, yes. They carry common tile profiles and can usually source matching replacements, including reclaimed materials. They advise on options for unusual or discontinued profiles.
Is the roofing work carried out by the owner?
Yes. The owner says he attends every job personally, and the business states that work is not subcontracted.
