Large-Scale Roofing Built to Withstand Site Conditions
Industrial roofs cover more ground and take more punishment than a typical house roof - standing water, foot traffic from maintenance access, and exposure to plant and machinery all shorten a roof life if it is not specified and installed properly.
We install and repair built-up felt, single-ply membrane, fibreglass and corrugated sheet roofing on commercial and industrial buildings, and can work around live sites with access equipment where needed.
Many industrial roof problems start small – a split membrane seam or a corroded fixing – and get expensive fast once water reaches steelwork or stored stock. Regular inspection catches this before it becomes a shutdown.

Signs Your Industrial Roof Needs Attention
The usual warning signs on a commercial or industrial roof.
Ponding Water
Standing water on flat industrial roofs after rain is one of the earliest signs of a sagging deck or blocked outlet.
Split or Perished Membrane
UV and thermal movement can crack felt and single-ply membranes at seams and upstands.
Corroded Fixings & Sheets
Rust around fixings on corrugated sheet roofs is a common cause of leaks over stored stock or machinery.
Damaged Rooflights
Cracked or discoloured GRP rooflights let water track into the building below.
Water Staining Inside
Internal staining on ceilings or steelwork is often the first visible sign of a roof problem that has been building for a while.
Blocked or Undersized Guttering
Industrial roofs shed a lot of water fast - undersized or blocked gutters overflow onto walls and foundations.
