In Coventry, like much of the West Midlands, many commercial buildings carry roofs that have seen decades of service. Some are still holding up; many more are letting in water, showing signs of corrosion, or simply looking tired. We specialise in liquid-applied membranes that seal and protect these roofs, often extending their life by years. It’s about keeping water out of your building, stopping rust creep on exposed elevations, and protecting the side that takes the prevailing weather. We won’t sell you a coating if it’s the wrong solution for your building, but if it is right, we’ll deliver a lasting job.
Commercial roof coating projects in Coventry
Coventry’s skyline was rebuilt in a hurry, and much of its commercial roofscape dates from that post-war push and the industrial decades after it. Sixty and seventy years on, plenty of those roofs are still doing their job, just not as well as they used to. This service exists for that middle stage: a roof that is structurally sound but leaking at laps, rusting at sheet ends or crazing across old felt. A liquid-applied membrane over a properly prepared surface seals it all into one continuous layer, at a fraction of the cost and disruption of replacement.
The work succeeds or fails on assessment and preparation. So, we start with a survey, not a sales visit. The difference between roof painting that lasts and a coat that fails early is preparation, and that is where the Coventry survey earns its keep.
The journey from initial inspection to full weatherproofing
The sequence is consistent on every job. A physical inspection records substrate, seams, fixings, rooflights, drainage and moisture condition, all photographed. A written report follows with a recommendation, and where a coating is right, a specification naming the system, the preparation and the detailing. Preparation is completed in full before application, and the coating goes on within the manufacturer’s conditions for temperature and curing. Occupied buildings stay occupied: we sequence the work around your operation. From Coventry, we also cover Nuneaton, Warwick, Leamington Spa and Birmingham, so multi-site operators across the West Midlands can run everything through one survey programme, ensuring consistent corrosion protection and weatherproofing.
When a roof coating isn’t the right choice
Some of the most useful reports we write recommend against our own service. Coating is the wrong move where:
- Insulation within the roof build-up is saturated
- Decking or sheet bodies are corroded or rotted through
- Fixing failure is widespread rather than localised
- Ponding is caused by structural deflection, not drainage
- Aged cement sheets are too brittle to work over safely
In those situations, the report sets out repair or replacement options instead. Sealing moisture or decay into a roof does not extend its life; it hides the countdown.
What we see on commercial roofs in the West Midlands
Around Coventry and the wider West Midlands, the typical commercial roof falls into a few families. Factory and warehouse units carry profiled steel, where cut-edge corrosion and loosened fixings are the usual suspects. Older works and depots still wear asbestos cement, porous and brittle with age and needing careful evaluation before any work is planned over it. Flat roofs on offices, retail and post-war buildings run to asphalt, built-up felt and, more recently, single-ply, each ageing in its own way.
A survey identifies which family your roof belongs to and, more importantly, what condition it is genuinely in, because the gap between ‘looks fine from the ground’ and ‘sound enough to coat’ can be wide.
Why a thorough survey delivers better value than the lowest bid
On paper, two quotes for the same roof can look interchangeable. In practice, the lower one has usually removed the parts you cannot see: the moisture checks, the corrosion treatment, the primer suited to the substrate, the patience to wait for application weather. Those are precisely the parts that determine whether the membrane lasts its expected life or fails early at the details. A survey-led contractor keeps them in and shows the working. For Coventry businesses with production, stock or tenants under the roof, that transparency is the real product; the coating is just how it is delivered, ensuring long-term weatherproofing and protection.
