Why choose GRP fibreglass roofing in Aldridge?

Landlords and small businesses in Aldridge often favour GRP on roofs that contractors need to access for plant, aerials or gutter clearance. The surface resists scuffs better than a soft membrane, and small damage can usually be ground back and re-laminated without disturbing the rest of the roof.

In a town like Aldridge, flat roofs are commonly found on low-rise post-war blocks of flats or lock-up garage blocks on estates. England averages roughly 870 mm of rain a year and the West Midlands sits close to that, so falls and outlets are the difference between a roof that drains and one that ponds.

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?

  • Removal of the old covering and disposal of waste
  • New OSB3 or plywood deck, fixed at close centres
  • Resin and glass-mat laminate with taped and reinforced joints
  • Moulded GRP trims, kerbs and upstands

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. 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.
