Warehouse Roofing & Roof Repairs

Warehouses present unique roofing challenges. Their large roof areas, low pitches and long spans mean that even minor defects can lead to significant water ingress. Leaking roofs cause damage to stock, disrupt picking and packing operations, create slip hazards and can even trigger insurance claims. The longer a problem is left, the worse — and more expensive — it becomes.

At Storm Coatings, we specialise in warehouse roof repairs that address the root cause of the problem, not just the symptoms. Whether you are dealing with isolated leaks, widespread corrosion, failed fixings, degraded sealants or ponding water, we have the expertise and the systems to fix it properly and permanently.

Our approach is always refurbishment first. We restore and protect your existing industrial roof cladding rather than replacing it, saving you a significant amount of money and avoiding the major disruption that comes with a full re-roof. Only when a roof is genuinely beyond repair would we recommend replacement — and in our experience, that is rare.

Roof Coating Systems for Warehouses

Our primary solution for warehouse roof repairs is the application of high-performance liquid roof coatings. These coatings form a seamless, fully waterproof membrane over the entire roof surface, sealing every joint, fixing, overlap and penetration point. The result is a completely watertight roof that resists further corrosion, reflects solar heat and adds decades of serviceable life.

We use a range of advanced coating systems tailored to the specific substrate and condition of your warehouse roof. Our team completed a 1,700m² CEC treatment project for a large factory unit in Derby — a typical example of the scale of work we handle day in, day out. Whether your warehouse is 500m² or 50,000m², we have the capacity and the experience to deliver.

Cut-Edge Corrosion on Warehouse Cladding

Cut-edge corrosion is the single most common defect we see on warehouse roofs. It occurs where the protective coating on profiled metal sheets has been cut during manufacture, leaving exposed steel edges that corrode over time. The corrosion spreads under the factory finish, causing delamination, flaking and ultimately water ingress through the sheet laps.

Our specialist cut-edge corrosion treatment halts the deterioration, seals the affected laps and provides long-term protection against further corrosion. It is specifically designed for industrial roof cladding and is a fraction of the cost of re-cladding your warehouse roof.

Gutter Repairs and Plygene Lining

Warehouse gutters take a huge volume of water, and when they fail, the results are dramatic. Corroded, cracked or blocked gutters overflow directly into the building, causing damage to stock, equipment and flooring. Our Plygene gutter lining system provides a permanent, maintenance-free solution. We install a seamless Plygene liner over the existing gutter, eliminating leaks and overflows for good. Our 145-metre Plygene gutter lining project at a distribution centre in Milton Keynes is a prime example of the results we achieve on large warehouse buildings.

Roof Light Replacement and Repair

Fragile, cracked or discoloured roof lights are a common problem on warehouse roofs. They let in water, reduce natural light levels and present a serious fall-through hazard. We replace damaged roof lights with modern, non-fragile GRP units that are watertight, translucent and compliant with current safety regulations. We can also apply coatings to existing roof lights to improve waterproofing and UV resistance.

Fixing and Fastener Replacement

Over time, the fixings that secure industrial roof cladding sheets to the purlins can corrode, loosen or fail. This allows sheets to lift in high winds, creates rattling and noise, and opens up gaps for water ingress. We carry out systematic fixing replacement programmes, removing corroded fasteners and replacing them with new stainless steel or bi-metal fixings complete with neoprene sealing washers.

• Save 50–70% compared to re-roofing — our coating and repair systems deliver outstanding performance at a fraction of the cost of full roof replacement.
• Protect your stock — a watertight roof means no water damage, no spoiled inventory and no insurance claims.
• Large-span experience — we work on warehouses of all sizes, from small trade units to massive distribution centres spanning tens of thousands of square metres.
• Minimal operational disruption — all work is carried out from above, so your warehouse continues to operate as normal throughout the project.
• 20+ year guarantees — our systems are backed by long-term manufacturer guarantees, giving you confidence in the investment.
• Rapid response — we understand that warehouse leaks are urgent. We mobilise quickly to stop the immediate problem and then deliver a permanent solution.
• Free surveys and honest advice — we assess your roof at no cost and recommend the most appropriate and cost-effective solution.
• UK-wide coverage — based in Norfolk, we carry out warehouse roof repairs and refurbishment projects across the entire UK.

Our warehouse roof repairs service covers every type of warehouse and storage facility, including:

• Distribution and fulfilment centres — large-span buildings handling high-value stock
• Cold stores and temperature-controlled units — where roof integrity is critical to maintaining the cold chain
• Self-storage facilities — multi-unit buildings where individual bays must be watertight
• Trade and wholesale units — trade counters, builders’ merchants, cash-and-carry stores
• Agricultural stores — grain stores, fertiliser stores, machinery buildings
• Archive and document storage — where water damage to paper records is irreversible
• Manufacturing warehouses — combined production and storage facilities

How quickly can you respond to a warehouse roof leak?

We understand the urgency of a leaking warehouse roof — water damage to stock can cost thousands in a matter of hours. We aim to carry out an initial assessment within 48 hours of your call, and in emergency situations we can often attend sooner. Temporary repairs to stop the immediate leak can typically be completed on the same visit, with a permanent solution quoted and programmed shortly after.

Can you repair a warehouse roof without us having to clear the building?

Yes. All of our warehouse roof repairs and coating work is carried out from the outside, on top of the existing roof. There is no need to empty the warehouse, relocate stock or halt operations. Your team can continue working as normal throughout the project, with the only visible sign of our presence being our access equipment on the roof.

Is it worth coating an old warehouse roof or should we just replace it?

In the vast majority of cases, coating is the smarter choice. If the structural integrity of the industrial roof cladding sheets and purlins is sound — which it usually is, even on roofs that are 30 or 40 years old — a high-performance coating system will restore full waterproofing and add 20 or more years of life. Replacement only makes sense when the sheets are physically damaged beyond repair or the structure itself is compromised. Our free survey will give you an honest, expert assessment.

How much do warehouse roof repairs cost?

Costs vary depending on the size of the roof, the extent of the repairs needed and the coating system used. As a general guide, our warehouse roof repairs and coating solutions cost between 50% and 70% less than a full re-roof.
