Our commercial roof had suffered from repeated leaks and years of temporary patch repairs. The initial survey was thorough and highlighted the areas requiring repair, corrosion treatment and protective coating. Communication remained excellent throughout the project, the site was kept organised and we received progress photographs at every stage. Since the work was completed, we have experienced no further water ingress.

Coating Networks vs a Local Contractor: 7 Questions to Ask
Many "nationwide" coating brands are sales offices that subcontract your roof to whoever is available. Before you sign, ask these seven questions. The answers are all checkable.

Why this matters before you sign anything
Commercial roof and wall coating is a survey-led trade: the quality of the job is decided by who actually stands on your roof, what they find, and who is accountable afterwards. Some of the most visible names in the market are marketing and call-handling operations that pass the work to third-party installers. That model is not automatically bad, but you should know exactly what you are buying. These seven questions separate a contractor from a middleman in one phone call.
Client feedback
What clients say about our work
We instructed the company to respray several occupied industrial units across our estate. Access and working areas were organised carefully, tenants received plenty of notice and there was minimal disruption to daily operations. The colour and finish are consistent across every unit.
David K.Industrial Estate Owner, CoventryThe grain-store roof had corrosion developing around the sheet edges and fixings. We received a clear explanation of the problem, photographs of the affected areas and a sensible quotation. The work was completed neatly and on time.
Thomas E.Grain Farm Owner, CambridgeshireWe had several areas of cracked render and faded exterior walls. Everything was repaired properly before the coating was applied, and the finished building looks clean, modern and professionally maintained.
Rebecca S.Commercial Property Manager, BristolThe factory remained operational throughout the project, which was essential for us. The team followed our site procedures and completed the roof coating safely and efficiently.
Michael B.Factory Manager, ManchesterWe thought the machinery shed would need completely recladding, but they recommended a more affordable coating solution. It now looks years younger.
Peter C.Agricultural Contractor, ShropshireThe team kept us informed throughout and carefully planned the work around customers, tenants and delivery vehicles.
Claire M.Retail Park Manager, NottinghamOur warehouse cladding was badly faded. The new coating has completely transformed the appearance of the building.
Andrew T.Warehouse Owner, BirminghamThey worked around the livestock and daily farm routine without causing us any problems. Proper job.
James R.Dairy Farmer, SomersetThe work was completed on schedule and caused very little disruption to the estate.
Susan W.Estate Manager, YorkshireReliable team, tidy workmanship and a very professional finish.
Mark H.Commercial Landlord, OxfordExcellent work. The barn looks brand new.
Daniel P.Farm Owner, LincolnshireThe checklist
Seven questions, one honest picture
1. Who actually attends?Will the person who surveys and quotes be the same organisation that does the work, or is the job passed to a third-party installer you have never met?
2. Who employs the installers?Ask directly: are the operatives employed by the company you are paying, or subcontracted? Who checks their work?
3. Whose warranty is it?A "20-year warranty" is often the coating manufacturer's product warranty, not a workmanship guarantee. If the application fails rather than the product, who fixes it?
4. Where is the office?A national coverage claim with one distant office usually means subcontracting. How far away is the team that would come back if something goes wrong?
5. How big is the company?Companies House is free and public. Check directors, filing history and whether the trading name matches the registered business.
6. Are the case studies real?Named buildings, real towns and photographs of actual jobs, or anonymous stock cards repeated across the website?
7. Who answers after handover?Snagging, leaks and warranty claims happen years later. Will the brand that sold the job still be the one answering the phone?
Where we stand
How National Coating Specialists answers these
We are a survey-led contractor, not a call centre. One of our surveyors inspects the building, photographs the condition and quotes only what it needs, and we tell you plainly when coating is not the right answer: sometimes the honest route is repair or replacement. Our advice is free, written and tied to the actual condition of your building. Start with a free site survey, or read about our commercial roof coatings and commercial wall coatings.

Common questions
Choosing safely
Is a subcontracted coating job always worse?
Not always. Good subcontractors exist. The problem is accountability: when the brand that sold the job, the installer who did it and the manufacturer who made the coating are three different organisations, a failure can turn into a season of finger-pointing. Knowing the structure before you sign lets you judge the risk honestly.
What is the difference between a product warranty and a workmanship guarantee?
A product warranty comes from the coating manufacturer and covers the material failing. A workmanship guarantee covers the application: preparation, detailing and installation. Most coating failures are application failures, so ask who stands behind the workmanship, for how long, and in writing.
How do I check a contractor on Companies House?
Search the registered company name at find-and-update.company-information.service.gov.uk. Check the directors, the incorporation date, the SIC codes (what the business is registered to do), and whether accounts and confirmation statements are filed on time. It takes five minutes and it is free.
