Industrial Roof Coating Systems and Specification Service
Industrial roofs deteriorate from the top down. UV breaks down the factory-applied paint finish. Rain pools in low spots and corrodes fixings. Thermal cycling expands and contracts metal sheets, opening joints and cracking sealant lines. Cut edges and drill holes , left unprotected during original installation , corrode first and spread outwards. A roof that looked sound 5 years ago develops pinhole leaks, stained ceiling tiles, and damp patches that steadily worsen. At that stage the building owner faces a choice: full reroof at £40 to £80 per m², or a specialist roof coating at £10 to £25 per m² that seals the surface, arrests corrosion, and adds 15 to 20 years of weather protection.
Anglia Decor applies spray-applied roof coating systems to profiled steel sheets, standing seam metal roofs, built-up cladding systems, and asbestos cement sheets. For metal roofs, acrylic-based elastomeric coatings provide a flexible, UV-stable membrane that stretches with thermal movement and bridges hairline cracks. For roofs with existing leaks at fixings, laps, and penetrations, a full roof spraying programme combines targeted sealant repairs with a spray-applied topcoat across the entire roof surface. Asbestos cement roofs receive specialist encapsulation coatings that seal the surface, prevent fibre release, and reinstate waterproofing , extending the roof's life while avoiding the cost and regulatory burden of asbestos removal.
Colour options include standard grey, white, and green, with RAL colour matching available for visible roofs on commercial and retail buildings. White and light-coloured coatings reflect solar heat, reducing internal building temperatures by 5 to 10°C in summer , a measurable benefit for warehouses, production facilities, and temperature-sensitive storage areas.
Roof Coating Application by Specialist Contractors
Industrial roof spraying starts with a full roof condition survey. Anglia Decor inspects the entire roof surface , sheets, fixings, laps, ridge caps, valleys, gutters, rooflights, and penetrations , to map areas of corrosion, coating failure, sealant breakdown, and structural damage. Defective fixings are replaced. Corroded lap joints and ridge caps are sealed with flexible polyurethane or butyl sealant. Rooflights are cleaned and resealed. Gutter joints and outlets are checked and repaired. That repair programme brings the roof back to a sound, watertight condition before the coating goes on.
Surface preparation involves pressure washing the entire roof at 2,000 to 3,000 PSI to remove dirt, moss, lichen, algae, chalk residue, and loose coating. Corroded areas are wire-brushed or mechanically abraded and spot-primed with anti-corrosion primer. The full roof surface is then primed with a bonding primer and topcoated by airless spray in 2 coats. Application rates and film thicknesses follow the coating manufacturer's specification , typically 200 to 300 microns total dry film thickness for metal roofs, 400 to 600 microns for asbestos encapsulation systems. Work is carried out from the roof surface using crawl boards, safety harnesses, and edge protection to HSE work at height regulations.
Anglia Decor has coated industrial roofs on factory units, distribution warehouses, retail stores, school buildings, agricultural buildings, and MOD facilities. Roof areas range from 500 m² single-bay units to 20,000 m² multi-span distribution centres. Weather dependence is managed by scheduling work in dry periods with ambient temperature above 5°C. A typical 2,000 m² industrial roof takes 5 to 8 working days from survey through to completion.

Frequently Asked Questions
How much does industrial roof spraying cost?
Roof coating typically costs £10 to £25 per m² depending on roof condition, access, and coating system. Full reroof costs £40 to £80 per m². Anglia Decor provides a fixed-price quotation after the roof survey.
How long does a roof coating last?
A professionally applied elastomeric roof coating lasts 15 to 20 years. Asbestos encapsulation systems last 20+ years. Lifespan depends on the building's exposure, roof pitch, and maintenance regime.
Can you coat an asbestos roof?
Yes. Specialist encapsulation coatings seal the surface, prevent fibre release, and reinstate waterproofing. This extends the roof's life while avoiding the cost and regulatory burden of full asbestos removal. All work follows HSE asbestos regulations.
Does roof coating stop leaks?
The coating itself is a waterproof membrane, but existing leaks at fixings, laps, and penetrations are repaired with sealant before the coating is applied. The combination of targeted repairs and full surface coating creates a comprehensive waterproofing system.
Can you spray a roof while the building is operational?
Yes. Roof spraying is external work with no internal disruption. Pressure washing may cause minor noise. All work is carried out with full edge protection and safety harnesses.
Do white roof coatings reduce building temperature?
Yes. White and light-coloured coatings reflect solar heat and can reduce internal temperatures by 5 to 10°C in summer. This is a measurable benefit for warehouses, food storage, and temperature-sensitive environments.
