Commercial roofs take far more punishment than domestic ones. Larger surface areas collect more standing water, flat or low-pitch sections are prone to ponding, and the sheer scale of a commercial building means a small defect can open up into a serious leak before anyone notices. Whether you run a warehouse unit on the edge of Thetford, a retail premises in the town centre, a farm building near Mundford, or a light-industrial facility out of town, the roofing challenges are the same: keeping water out, keeping heat in, and keeping the roof performing year after year with minimal fuss.
Commercial roofing covers a wide range of systems and materials. Flat or near-flat roofs are common on industrial units, extensions and single-storey commercial buildings. These are most often finished in built-up felt, single-ply membrane or EPDM rubber sheeting. Each system has a different expected service life and different failure points, so the right repair or replacement approach depends entirely on what is already there and what condition it is in.
Pitched commercial roofs, including those on older buildings, are usually clad in fibre cement sheeting, metal profiled panels, or natural slate. Common problems include:
A full refurbishment typically starts with a close inspection from the roof itself, not just from the ground. We check the deck for soft spots, inspect all outlets and rainwater goods, and look at every flashing and upstand. On flat roofs, we also check for blistering, splitting or delamination of the membrane. Only once we know the full picture can we quote accurately for what is actually needed.
Felt flat roofing has been used on commercial buildings for decades. Modern torch-on felt systems are a significant step up from the old cold-applied or single-layer materials used on buildings constructed before the 1990s, and a properly installed torch-on system on a sound deck will perform well for many years. EPDM rubber is increasingly popular on smaller commercial flat roofs because it handles ponding water well, stays flexible in cold weather, and does not crack the way older felt can.
Typical costs for commercial flat roof replacement in Norfolk run from around £70 to £120 per square metre depending on the system specified, the condition of the existing deck, and the complexity of the roof edge details. Larger areas often come in towards the lower end of that range because the setup costs are shared across more square metreage. These figures are a general guide; the actual price for your building will depend on a proper inspection.
Full replacement is not always necessary. Where a roof deck is sound and the covering is failing in isolated areas, targeted repairs can extend the life of the roof by a useful number of years and cost a fraction of a full strip and re-cover. We assess each roof on its own merits. If a repair is the right answer, we say so. If the roof is too far gone for repairs to be worthwhile, we explain why rather than patching it and leaving you with the same problem in twelve months.
Refurbishment work, such as over-coating an existing flat roof with a compatible liquid membrane, can be a cost-effective middle ground where the structure is sound but the surface is weathered and starting to admit moisture. This approach adds a new waterproof layer without the disruption and waste of a full strip.
Commercial buildings generate large volumes of rainwater runoff, and their guttering systems are sized accordingly. Box gutters are a particular weak point: they sit below the roof surface, carry heavy loads of water, and when they block or fail, the water has nowhere to go except into the building. We clear, repair and re-line box gutters, replace failed outlets, and re-seal or replace valley and parapet flashings where they have lifted or corroded.
Wall cladding on industrial and commercial units takes the same wind and rain as the roof itself. Laps that have pulled apart or fixings that have worked loose let water into the wall cavity and can cause significant damage to insulation and structural steelwork before it is spotted. Cladding repairs and replacements on commercial buildings are part of the same scope of work for us.
Commercial roofs on exposed sites are subject to significant wind. Buildings on the outskirts, or those without the shelter of other structures, can see wind uplift pulling at fixings and joints that would last far longer in a more sheltered urban setting. We work across Thetford and in the surrounding towns and villages including Watton, Attleborough, Brandon, Mildenhall, Methwold, Feltwell and Mundford.
Moss is a particular issue on commercial roofs close to the forest edge and on older agricultural and industrial buildings where the surrounding vegetation is dense. Moss holds moisture against roofing materials, accelerates the deterioration of felt and fibre cement, and can block gutters and outlets to the point where water backs up across the whole roof. Getting moss treated and cleared before it causes structural damage is worth doing on a planned basis rather than waiting until there is an active leak.
A professional commercial roofing job should leave you with written details of exactly what work was carried out, what materials were used, and the specification that was followed. You should be able to see the completed work from access points where it is safe to do so, and any debris or stripped material should be cleared from the site. Good practice on a commercial job also means thinking about how the work is sequenced to avoid leaving open areas of roof overnight or over a weekend.
Commercial flat roofs in Thetford and across Norfolk typically cost between £70 and £120 per square metre for a full re-cover using torch-on felt or EPDM rubber, depending on the size of the roof and the condition of the existing deck.
