FAQs
What exactly is a reflective coating for metal roofs and how does it work?
A reflective roof coating is a liquid-applied membrane, usually white or light-coloured, that cures into a seamless, highly reflective surface on top of your existing metal panels. The pigments and additives inside the coating bounce back a large portion of the sun’s infrared and ultraviolet radiation rather than absorbing it. By reflecting heat away, the coating keeps the metal substrate cooler, reduces thermal expansion and contraction, and acts as an additional waterproof barrier against rain and Bristol’s frequent winter showers.
What advantages will a reflective coating give my metal roof in Bristol’s climate?
• Energy savings – A reflective coating can lower rooftop temperatures by 20–30 °C, reducing the workload on air-conditioning systems and cutting summer cooling bills by up to 25 %. • Extended roof life – Lower temperatures and extra UV protection slow down corrosion, chalking and paint fade, adding 10–15 years to the roof’s service life. • Leak prevention – The elastomeric film seals minor seams, fasteners and hairline cracks, providing a continuous waterproof layer that resists wind-driven rain common in the South West. • Improved comfort – Interiors stay noticeably cooler during heat waves, and temperature swings that cause metal to “oil-can” or make popping noises are minimised. • Sustainability – Reflective coatings are classed as "cool roofs", helping to reduce Bristol’s urban heat-island effect and lowering a building’s overall carbon footprint.
How long will a reflective coating last on my metal roof and when will I need to recoat?
Service life depends on the product chosen, film thickness and roof exposure, but modern acrylic and silicone systems typically last 10–15 years before a maintenance recoat is needed. A scheduled inspection every 2–3 years to clean the surface and touch up high-wear areas can extend that cycle. Because the original metal remains in place, future recoating is simple: a light power-wash, minor repairs and a fresh top layer restore full performance at a fraction of replacement cost.
Will applying a reflective coating change the look of my roof?
Most coatings come in bright white for maximum solar reflectivity, but tintable versions in light grey, beige and pastel colours are available if you prefer a softer tone. The finish is usually satin to semi-gloss, giving the roof a clean, uniform appearance that hides patchy paint or rust stains. If you currently have a coloured architectural metal roof and wish to retain the exact hue, a clear ceramic-based coating can be used to add reflectivity without altering the original colour.
Can any metal roof be coated, even if it’s older or lightly rusted?
Yes. Galvanised steel, aluminium, zinc, copper and previously painted systems can all be coated as long as the deck is structurally sound. For older roofs we carry out a four-step prep: (1) pressure-wash to remove dirt and chalk, (2) mechanically abrade light rust, (3) apply a rust-inhibiting primer, and (4) seal seams and fasteners with reinforcing mesh or butyl tape. Severely corroded panels with holes must be replaced before coating, but in most cases restoration is quicker and cheaper than full reroofing.
What does the installation process involve and will it disrupt my home or business?
A typical 500 m² commercial roof in Bristol takes 2–3 days from start to finish. Day 1 – inspection, repairs and cleaning; Day 2 – primer application and seam sealing; Day 3 – spray or roller application of the reflective top coat. All work is performed from the roof exterior, so there is minimal disturbance inside your property. Equipment is low-odour and low-VOC, meaning normal business operations can continue, and our installers schedule around peak customer or production hours when necessary.
