We install and repair flat roofs on extensions, garages and commercial units, using felt, fibreglass, rubber and liquid plastic systems chosen to suit the job and your budget. GRP fibreglass forms a single seamless surface with no joints to fail, which is why it’s become the most popular choice for domestic extensions in recent years.
If you’re replacing an old felt roof, we’ll often suggest a more modern system such as fibreglass or single-ply rather than like-for-like, and talk you through the pros and cons of each. We can also discuss rooflights or upstands for extractor vents as part of the same job.
Flat roof problems often start at a joint, upstand or outlet rather than the flat surface itself, so that’s where we focus our attention during a survey. Getting these details right first time makes a real difference to how long the roof lasts.
