Commercial roofs are a different proposition to domestic ones. The surface areas are larger, the access requirements are more complex, and the consequences of getting it wrong - stock damage, business downtime, tenant disputes - are far more serious. Brandon Roofers works on commercial properties in and around Mundford, handling everything from survey and diagnosis through to full flat roof replacement using felt or EPDM single-ply systems.
For larger projects or planned replacements, we schedule work around your business hours to reduce the impact on staff and customers.
Many commercial buildings have flat or very low-pitch roofs. The systems we work with include traditional built-up felt (multiple layers of bituminous felt bonded in sequence), EPDM rubber membranes (a single-ply system with a strong track record on large flat areas), and torch-on modified bitumen felt for roofs where a robust, straightforward specification is the priority.
We also carry out work on pitched commercial roofs - fibre cement or metal sheet roofing on agricultural and industrial buildings, and concrete or clay tile roofing where the building requires it.
All flat roof work includes assessment of the drainage layout, upstand heights, and deck condition before any material is specified. These are not optional extras - they are what determines whether the new roof performs properly or fails within a few years.
Commercial flat roof replacement in the UK typically costs between £30 and £90 per square metre installed, depending on the system and specification. Built-up felt at the simpler end of the range will sit around £30-£50 per square metre. EPDM single-ply, which requires less labour on very large surfaces but higher material costs, typically runs £50-£90 per square metre. These figures assume a structurally sound deck - if the deck itself needs replacing or significant repair, that adds to the total.
Partial repairs to a flat roof, where only a failed section or a specific leak point is being addressed, can cost anywhere from a few hundred pounds for a localised patch to several thousand for a section replacement including insulation. The only way to get a reliable figure is to have the roof inspected first, so the extent of any wet insulation or deck damage can be assessed properly.
If you have identified a commercial roof problem and a roofer is coming out to survey or repair it, the time between discovery and fix matters. Handled sensibly, you can limit further damage. Handled badly, you can create additional problems or, in some cases, make the repair more expensive.
Document the damage from the inside. Take photographs and short video clips of any internal water staining, wet ceiling tiles, drips, or damp walls. Note the date and time. If the leak appears after a specific weather event - heavy rain, a storm, a frost - record that too. This information is genuinely useful to a roofer: patterns of when a leak appears and where the water tracks internally help narrow down where to look on the roof. It also protects you if the matter involves tenants or insurers.
Contain the water, not the airflow. If water is dripping through a ceiling void or a ceiling tile, place a container beneath the drip, but if the ceiling is bulging, keep everyone out of that area and do not poke, prod or pierce it. A ceiling that is allowed to fill with water can collapse under the weight. Do not seal vents or block airflow in the roof void trying to divert water - this can trap moisture and accelerate rot in timber elements.
Move stock, equipment, and electrical items away from the affected area. This sounds obvious, but in a busy warehouse or retail environment it is easy to assume a small drip will not reach the pallet or the switchboard nearby. Move anything of value or anything electrical out of the risk zone while you wait.
Keep a note of what the leak is doing over time. Is it getting worse with sustained rain? Does it dry up when the rain stops? Does it appear hours after rain begins, or immediately? A leak that appears many hours after rainfall often indicates water is tracking a long distance from where it enters the roof, which is important information for diagnosis. A leak that appears immediately and stops when rain stops is more likely to be a direct penetration at a specific point.
Make sure the roofer can safely access the building and the roof. If the building is normally locked, arrange for someone to be on site. If there is plant or racking close to the roof access hatch or ladder, clear it in advance. Safe roof access on a commercial property often involves more planning than on a house, and delays caused by access problems add to your cost.
Do not go onto the roof yourself. This is the most important point. Commercial roofs present serious fall risks. Without proper edge protection, harnesses, and familiarity with the surface condition, going onto a commercial flat roof is dangerous. Bitumen felt and single-ply membranes can be slippery when wet. Roof edges and rooflights are not always visually obvious from above. Falls from commercial roof heights are frequently fatal. This is not a job for a general handyman or a member of your own staff, however practical they are on the ground.
Do not apply DIY sealants or waterproofing products to a commercial roof. Products sold as roof sealants or liquid waterproofing coatings are not a substitute for proper roofing work on a commercial building. Applied incorrectly, they can mask the true extent of a problem, make subsequent proper repairs more difficult, and in some cases trap moisture in the build-up. A roofer who arrives to find a roof coated in DIY product has a harder job diagnosing the problem accurately and may need to strip the coating before they can work properly.
Do not attempt to repair lead or metal flashings yourself. Flashings at parapet walls, around rooflights, and at penetrations are precision work. Poorly reformed or incorrectly dressed metal flashings create new leak paths and can lift in wind. If a flashing has come away, leave it and report it to the roofer rather than trying to push it back and seal over it with mastic.
Do not delay reporting a new leak, even a small one. A slow drip that appears manageable will almost always get worse with the next significant rainfall. More importantly, every week that water sits in the roof build-up, it is saturating insulation and degrading the deck. Saturated insulation must come out and be replaced - it does not dry back to its original performance. Delay is directly proportional to the size of the repair bill.
Do not assume the leak is directly above the internal stain. Water on a commercial flat roof travels. It enters through a defect - a failed upstand, a cracked outlet collar, a split in the membrane - and then follows the fall of the deck until it finds an exit point, which may be some distance from the entry point. If you are tempted to probe or test the roof surface yourself based on where the ceiling is wet, you are likely looking in the wrong place. Let the roofer carry out a proper inspection of the whole roof, not just the area above the stain.
A commercial roof survey is not a five-minute walk-around. On a roof of any significant area, a thorough survey will include inspection of the membrane surface for splits, crazing, blistering, and lifted seams; checking of all upstands, flashings, and penetrations; assessment of outlets and drainage; and ideally some form of testing for wet insulation, either by feel and probe or using electronic moisture detection equipment.
You should expect the surveyor to provide you with a clear description of what they found, what they recommend, and why. If they cannot explain the rationale for their recommendation, that is worth noting. The recommendation might be a targeted repair, a section replacement, or a full re-roof depending on the extent of any failure. Each of those is sometimes the right answer - the question is whether the contractor can demonstrate why they are recommending one over another.
For a full commercial re-roof, the planning stage matters as much as the installation. Key decisions include the choice of system, the specification of insulation thickness (which affects both thermal performance and cost), how drainage will be designed or corrected, and the programme of works to keep the building weathertight at each stage. On a large roof, the work will be sequenced in sections so the building is not fully exposed at any one time.
Access planning is also critical. Mobile elevated work platforms are often needed for commercial roofing and must be operated by trained personnel on a surface that can take the load. Scaffold may be required around parapets or on multi-storey structures. These costs are real and should appear in any proper commercial roofing quote - if a quote seems unusually low, it is worth asking exactly what access has been included.
