Commercial roofs encompass a wide range of systems and building types. We work on flat roofs using felt and EPDM rubber membranes, profiled steel and aluminium sheet roofs on agricultural and industrial buildings, box gutters on older commercial premises, and roof lights that let natural light into warehouses and workshops. Each system has its own failure patterns and its own repair logic.
For businesses in and around Burwell, and across the wider area including Haverhill, Clare, Steeple Bumpstead, Kedington and Ridgewell, the first question to ask is a straightforward one: should I repair this roof or replace it? The answer depends on several factors, and getting it right saves money in the long run.
There is no universal rule. A flat roof that is fifteen years into a twenty-year membrane life, with one localised split near an outlet, is probably a repair job. A flat roof where the membrane has lost its bond to the insulation across a large area, where water has been sitting in the build-up for months, and where two or three areas have already been patched in recent years, is probably not.
The mistake businesses make is treating a repair as always being the cheaper option. In the short term it costs less. Over three to five years, a roof that keeps being patched will cost more in call-out fees, internal damage from repeated leaks, and lost productivity than a replacement carried out once and properly.
Targeted repair is the right call when the damage is genuinely localised. A single split in a felt membrane, a failed sealant joint around a roof light, a blocked or cracked box gutter outlet, or a loose flashing at a parapet wall are all jobs where repair addresses a specific fault without disturbing a roof that is otherwise performing well.
Repair also makes sense when the roof is relatively young. An EPDM rubber roof that is five or six years old with a minor puncture or a failed joint at a penetration should be repaired. The membrane still has a long service life ahead of it, and a well-executed repair will hold without further problems.
A good contractor will take a core sample or carry out a moisture survey before recommending repair on an older roof. That tells you whether the insulation beneath the membrane is dry. If it is saturated, repair of the visible fault will not stop the slow deterioration of the deck and insulation below, and you will be back in the same conversation in eighteen months.
The following conditions generally indicate that a repair programme will not resolve the underlying problem and that replacement should be considered:
These figures are general industry benchmarks, not a promise about any specific roof, but they give useful context when you are weighing repair against replacement.
A properly installed torch-on felt flat roof on a commercial building typically lasts 15 to 20 years before the membrane degrades to the point where replacement is more practical than ongoing repair. EPDM rubber membranes generally outlast felt systems by a significant margin, with serviceable lives of 25 years or more when installed correctly and kept free of standing water. Profiled steel sheet roofs depend heavily on the coating specification: a standard plastisol coating may last 25 to 30 years before corrosion becomes a structural concern, while a premium coated sheet can perform for longer.
Box gutters on older commercial buildings are often the first point of failure regardless of the roof membrane condition. Cast iron and pressed steel box gutters corrode from the inside out, and the visible watermark on an internal wall may be months behind the actual point of failure. Addressing box gutter condition separately from the main roof membrane is often the right approach.
Flat roof replacement on a commercial building in this part of the country currently runs from around £40 to £90 per square metre depending on the system, the deck condition, and the drainage complexity. That is a significant spend on a large roof. But compare it with three or four call-out repairs per year at £300 to £800 each, internal damage remediation, potential stock or equipment losses, and the disruption to your business, and the arithmetic often shifts in favour of replacement sooner rather than later.
When getting quotes for either option, ask the contractor to give you a written assessment of the roof's overall condition, not just the fault they have been called to look at. A roofer who inspects only the obvious leak and quotes to patch it is not giving you the full picture.
A commercial roof replacement needs to be planned around your business operations. Access equipment, the sequence in which sections of the roof are stripped and covered, and the daily close-out procedure all matter. On a building that continues to trade during the works, the contractor needs to account for temporary weathering of open areas each day.
Ask your contractor how they handle the discovery of unexpected deck damage once the old membrane is removed. Rotted or delaminated deck boards are not always visible before strip-out, and a contractor who has no clear process for pricing and authorising additional work will either charge you a large surprise bill or cut corners on what they actually replace.
