GRP fibreglass roofing in Linlithgow

We lay GRP fibreglass roofs in Linlithgow on dormers, extensions, garages and small commercial buildings. A surveyor visits first, free of charge, to check the joists, measure up and see whether the roof suits fibreglass. You then get a fixed written price, and the work is done by vetted roofing teams working under S&K.

Why choose GRP fibreglass roofing in Linlithgow?

GRP is a good fit in Linlithgow for roofs with awkward shapes, short runs of upstand and lots of corners, because every detail is laminated in place rather than cut and glued. Where a sheet membrane would need many joins, fibreglass forms one continuous skin across the whole roof.

In and around Linlithgow, flat roofs are typically found on low-rise post-war blocks of flats, and on lock-up garage blocks on estates. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write.

Why do GRP roofs crack, and can weather affect the installation?

GRP usually cracks where the structure moves and the laminate cannot, typically along board joints, at the junction with trims, or where a roof meets a wall. Weather during laying is the other big factor, because resin cures by chemical reaction and that reaction is sensitive to temperature and moisture.

How we reduce the risk of cracking:

  • boards fixed at close centres so the deck does not flex;
  • joints taped and reinforced with an extra strip of mat;
  • wall junctions finished with a separate trim or flashing, not laminated hard into the masonry;
  • roofs over a certain size divided with movement details where the system calls for them.

And how weather is managed:

  • no laminating in rain, on a damp deck, or when dew or frost is likely before the resin sets;
  • catalyst levels adjusted for the temperature, so resin neither stays tacky on a cold day nor kicks too fast in summer heat;
  • the roof sheeted over if a shower threatens a fresh laminate.

That is why a GRP date can move at short notice. A day's delay costs far less than a laminate that never cures properly.

What's included?

  • Moulded GRP trims, kerbs and upstands
  • New OSB3 or plywood deck, fixed at close centres
  • Coloured UV-stable topcoat, with anti-slip finish on request
  • Removal of the old covering and disposal of waste

Building standards in Scotland

In Scotland the building standards technical handbooks (Section 6 for energy) apply, and the council's building standards service decides whether a building warrant is needed. Like-for-like repairs to a roof covering can be exempt; alterations, structural work and new roofs usually need a warrant before work starts. The domestic roof benchmark is 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. More on the rules.

Does GRP smell when it is being laid?

Yes, the resin gives off a strong styrene smell while it cures. It usually fades within a day or so, and we advise keeping nearby windows closed while the team works.

Can you walk on a GRP roof?

Yes, a correctly laid GRP roof takes occasional foot traffic, such as cleaning windows or maintaining plant. For a regular walkway or terrace, an anti-slip topcoat and a suitable specification are needed.
