When a commercial roof fails, it rarely happens overnight. The leak that appears on a Monday morning has usually been developing for months, sometimes years. We carry out the full range of commercial roofing work for Thetford businesses, from complete re-roofs to targeted repairs, and we understand that keeping your premises watertight and your operations running matters more than anything else.
We cover flat roof systems using built-up felt and EPDM rubber membranes, single-ply systems for larger low-pitch roofs, and profiled metal roofing for industrial and agricultural buildings. Each system has its own strengths and maintenance requirements, and part of our job is making sure you know what you have on your building and what it needs to keep performing.
A commercial roofing project is not the same as a domestic job scaled up. Access requirements are different, materials are specified to a higher loading, and there is usually an obligation to keep disruption to a minimum while staff, customers, or stock are below. We plan the sequence of work around your operating hours where possible, and we document the installation thoroughly so you have a clear record of what was laid, what was sealed, and where penetrations and outlets were treated.
For flat roofs, work begins with an assessment of the existing deck. A decayed or waterlogged deck cannot carry a new membrane without being repaired or replaced first. Skipping this step is one of the most common causes of early failure on commercial re-roofs. We check for soft spots, delamination in plywood decks, and standing water that points to falls being incorrect.
For profiled metal roofing on warehouses and industrial units, we inspect fixings, ridge cappings, and any roof lights, which are a frequent source of leaks as their seals age. Re-sheeting in modern coated steel or aluminium can transform both the weather performance and the appearance of an older building.
Commercial flat roofing using a quality EPDM rubber system typically costs in the region of £85-£130 per square metre, depending on access, deck condition, and roof complexity. Built-up felt systems tend to sit at the lower end of that range. Single-ply membrane systems for larger roofs are usually priced on specification. Profiled metal re-sheeting for industrial buildings generally runs from £50-£90 per square metre for the cladding alone, before scaffold and any structural work. These are honest typical UK ranges - your actual price depends on the specifics of the building.
This is the section most commercial roofing pages skip, and it is the one that makes the biggest practical difference to how long your roof lasts. A well-installed commercial roof can last 20-30 years, but neglecting basic maintenance can cut that figure significantly. The good news is that most of the maintenance a commercial roof needs is straightforward and low-cost if done at the right intervals.
A visual inspection twice a year, in autumn and spring, catches most problems before they become expensive. You do not need to go on the roof yourself - in many cases it is safer not to. What you are looking for from ground level or through a rooflight:
Keeping gutters and flat roof outlets clear is something most businesses can manage without calling a roofer. On a flat roof, the outlet is typically a domed or grated fitting that sits in the lowest point of the roof. Leaves, moss, and silt collect around it. If your site has trees nearby, clear these outlets at least twice a year. A compressed-air line or a gloved hand is usually enough. Do not poke metal tools into the outlet collar as this can damage the seal where the membrane is bonded to it.
Box gutters on commercial buildings are a particular problem. Because they are concealed within the building envelope, a blocked box gutter can overflow internally before anyone notices. If your building has them, get them rodded or jetter-cleaned annually. A roofer who cannot reach them safely should tell you so rather than leave them unchecked.
Small splits or lifted seams in a felt or EPDM membrane are straightforward to repair when caught early. Left open for a second winter, water tracks under the membrane, wets the deck, and by the time you see a stain inside, the deck may need replacing rather than just the surface. The repair cost at the early stage might be £150-£400 for a minor split. Left until the deck is affected, the same area can cost several thousand pounds to put right.
Flashings that have lifted or cracked at the pointing are another high-priority repair. Lead and code-4 aluminium flashings can be re-dressed and re-pointed without replacing the whole sheet in many cases. Silicone is sometimes used as a temporary fix - it can hold for a season but is not a long-term solution, and it can make a proper lead repair harder because silicone does not bond well to itself once weathered.
When a commercial roofing job is complete, ask for a written record of what was done. This should include the materials used (membrane type, felt specification, membrane thickness for single-ply), how penetrations and upstands were treated, and which areas of the existing deck were replaced or repaired. This record is useful for your own maintenance schedule, for insurers, and if you ever sell or re-let the premises.
Ask the roofer to walk you through the outlet and drainage points on the roof before they leave, and confirm what intervals they recommend for inspection given your specific roof type and local conditions. A roofer who gives you this information is more useful to you in the long run than one who just hands you an invoice.
