We cover commercial roofing work across the area around Kedington. The work covers flat roofs on felt and EPDM rubber systems, profiled steel and aluminium sheet roofs, box gutters, and roof lights on all types of commercial and agricultural buildings.

When a commercial roof develops a problem, the gap between spotting it and getting a contractor on site can be hours or days. What you do in that window matters, and what you avoid doing matters just as much. This page covers both: the practical steps to protect your premises while you wait, and the things that can make the situation worse if you attempt them yourself.

Identifying the problem accurately

Water appearing inside a commercial building does not always enter at the point where it shows up. On a flat roof, water can travel along the top of the deck or through the insulation layer before it finds a gap in the ceiling below. A water stain directly above a workbench may have entered the roof 3 or 4 metres away. Note the location, take photographs, and if it is safe to do so from the ground, look at the roof surface above the affected area for obvious pooling or debris.

On a profiled metal sheet roof, the entry point is more often close to the visible drip, because water follows the corrugations downward. Check the laps, the ridge, the fixings and any roof lights in the area directly above the leak.

What to do while you wait for the roofer

Protecting the interior of your building from ongoing water entry is the priority. These steps are practical, safe and will limit the damage without creating further problems:

• Move stock, equipment and records away from the affected area. Water from a roof leak is rarely clean. It picks up debris, moss, felt particles and rust from gutters on its way through, and it can contaminate materials that are not waterproof.
• Place containers under the drip and monitor them. This sounds obvious, but a container that overflows unnoticed causes as much secondary damage as the leak itself. Use larger containers than you think you need and check them regularly.
• Protect electrical equipment and isolate circuits if water is tracking near fittings. Water and electrical installations are a serious hazard. If there is any possibility of water reaching a light fitting, a distribution board or cabling, isolate the relevant circuit at the consumer unit and do not restore it until the area has dried out and been checked.
• Use plastic sheeting to cover anything that cannot be moved. Machinery, racking and goods that are fixed in place can be covered with heavy polythene to reduce contact with dripping water until the roof can be attended to.
• Document everything. Photograph the leak, the damage, the affected stock, and the roof surface if you can see it safely. That record is useful both for the roofer's assessment and for any insurance or business continuity claim.
• Report the situation to your landlord if you rent the premises. Commercial leases vary in how they allocate roof maintenance responsibility. Some place full repair obligations on the tenant, others on the landlord. Notifying your landlord in writing as soon as a problem appears protects your position regardless of who is responsible.

What not to do yourself

The instinct to get on the roof and do something is understandable when water is coming in and the business is affected. In most cases, it makes the situation worse. Here is what to avoid:

Do not attempt to access the roof without proper equipment and training. Commercial roofs are not designed to be walked on without knowing where the structural supports are. A felt or EPDM membrane over insulation boards gives no indication of where the deck is solid and where it is not. A foot through a roof creates a much larger problem than a failed joint or crack, and the fall risk from a commercial building is serious.

Do not apply DIY sealant or repair tape over an active leak without understanding what you are sealing. Butyl tape and roof sealant applied over a wet membrane will not bond properly and will not hold. More significantly, sealing over the visible fault without addressing the cause can redirect water to an adjacent area and make the roofer's diagnosis harder when they arrive.

Do not pressure wash or sweep debris off the roof into the outlets. Pushing debris toward the outlets in an attempt to clear them can block a partially functioning outlet completely. If an outlet is already restricting flow, forcing more material toward it will stop drainage entirely and increase ponding.

Do not remove roof light panels or sheet fixings. It may seem logical to open a roof light to allow water to escape or to investigate, but removing fixings on a profiled sheet roof or a roof light kerb can compromise the structural integrity of the detail and allow significantly more water entry.

Temporary weathering: what a roofer can do quickly

A commercial roofing contractor attending urgently is likely to apply a temporary weathering solution rather than carry out a permanent repair on a first visit, particularly if the roof is wet or if the extent of the damage is not yet clear. This typically involves heavy-duty roofing felt or a temporary membrane lap-bonded or mechanically fixed over the affected area to stop active water entry while a proper assessment is carried out and materials are sourced.

Temporary weathering is not a permanent repair. It buys time for the correct diagnosis, the right materials to be ordered, and the repair or replacement to be carried out properly under suitable conditions. Ask your contractor to confirm what the temporary measure involves and when they plan to return for the permanent work.

Flat roof repairs and replacements: what the work involves

A flat roof repair on a commercial building begins with identifying whether the fault is localised or whether the membrane has failed across a wider area. A contractor should go onto the roof, inspect the area above the leak, check the outlets and upstands, and if the cause is not immediately obvious, carry out a flood test or moisture survey before cutting in.

Flat roof replacement involves stripping the existing membrane and, where it has been compromised by water ingress, the insulation boards beneath it. The deck is then inspected for rot, delamination or deflection before new insulation and a new membrane are fitted. On an EPDM rubber system, the membrane is typically rolled out in large sheets with minimal seams, bonded with adhesive, and dressed around all upstands and penetrations. Costs for commercial flat roof replacement in this part of Suffolk and Essex currently run from around £40 to £90 per square metre depending on the system, the deck condition, and the complexity of drainage and upstand details.

Profiled metal sheet roofs

Industrial and farm buildings with profiled steel or aluminium sheet roofs develop leaks at fixings, at laps between sheets, at the ridge, and at any penetrations or roof lights. A roofer attending an emergency on a metal sheet roof will check fixings for failed neoprene washers, re-seal laps, and replace any sheets that have corroded beyond the point where sealing is effective. Full re-roofing of a profiled metal building involves removing the existing sheets and, where present, failed liner sheets and insulation, before fitting a new system, often with upgraded insulation to meet current thermal requirements.

Getting the repair right the first time

An emergency repair that holds for six months is worth less than a properly specified repair that performs for years. When the immediate crisis is under control, ask the contractor to carry out a full roof condition survey so you understand not just the repaired fault but the overall state of the roof. That tells you whether further work is likely in the near future and allows you to plan for it rather than be caught out again.
