Commercial roofs are a different animal from domestic ones. The spans are wider, the drainage details are more complex, and a failure during trading hours can cost far more than the repair itself. We work on flat roofs, profiled metal sheet roofs, box gutters, and roof lights across industrial units, retail premises, offices and agricultural buildings in and around Great Dunmow, as well as in nearby towns and villages.
Getting the right contractor is the single most important decision you make when something goes wrong with a commercial roof, or when a planned replacement is coming up. The sections below are written to help you ask the right questions before you agree to anything.
The commercial roofing market is not regulated in the same way as some trades, which means anyone can call themselves a commercial roofer. That puts the burden on you to separate capable contractors from ones who will leave you with a leaking roof and an argument on your hands.
Start by asking whether the contractor has direct experience with your roof type. Flat felt or EPDM rubber roofs, profiled steel or aluminium sheet roofs, and built-up systems all behave differently, fail differently, and need different repair approaches. A roofer who mainly works on domestic tiles may not be the right person for a 400-square-metre industrial flat roof.
Ask specifically about experience with box gutters. Box gutters are a common source of water ingress on older commercial buildings, and repairing them properly requires understanding how the upstand, the outlet and the surrounding roof surface interact. A patch over the visible crack rarely holds for long if the underlying falls are wrong.
The following are practical questions worth raising with any contractor before you sign anything or hand over a deposit. You are entitled to clear answers on all of them.
A quote for commercial roofing work should be itemised. That means separate line items for materials, labour, disposal of old materials, scaffold or access equipment hire, and any associated work such as replacing insulation boards or repairing structural decking. A single lump-sum figure with no breakdown makes it impossible to compare quotes from different contractors or to understand what you are actually paying for.
Be cautious of the lowest price. Flat roofing in particular has a wide range of material quality. A low-grade torch-on felt fitted without adequate insulation will fail faster and cost more over a ten-year period than a better membrane fitted correctly at a higher initial cost. Ask each contractor to justify their material choice, not just their price.
Profiled metal sheet re-roofing varies widely because the span, fixing specification and insulation thickness all affect the price significantly. The same is true of flat roof work, where the system specified, the condition of the deck, and the complexity of any drainage or upstand details all shape the final figure.
Pressure to start immediately without a written scope is a warning sign. A legitimate contractor will give you time to consider a written proposal. Equally, a very large deposit requested before any materials are ordered or work has started is unusual for an established business.
If a contractor inspects your roof from the ground only and quotes without going up, treat that price with scepticism. The true condition of a commercial flat roof, its drainage falls, the state of the insulation beneath the membrane, and the condition of upstands and flashings cannot be assessed from a car park.
A reactive call-out after a leak has already caused internal damage is the most expensive way to deal with a commercial roof. Planned maintenance, typically an annual inspection and minor repairs to pointing, sealant and flashing details, costs a fraction of an emergency repair and extends the serviceable life of the roof significantly.
Before any major repair or replacement, ask the contractor to walk the roof with you and explain what they are seeing. A good contractor will show you the problems, explain the cause, and give you a realistic picture of how long the roof has left if you carry out targeted repairs versus a full replacement. That conversation should happen before you commit to anything.
We carry out commercial roofing work across the area, including in nearby towns and the surrounding villages. If your commercial property is in or near Great Dunmow, call us to arrange a roof survey so we can give you an honest assessment and a written scope before any work begins.
