General Roofing Installation

We survey first: deck condition, span measurements, upstand heights, drainage falls and every location that will penetrate the roof — vents, cable trays, air-conditioning bases. The sheet layout is then set so fastener rows stay straight, cuts fall in the right places and waste is minimised.

Flashings are prefabricated to the actual profile and delivered with the sheets rather than improvised on site. Insulation is fitted while the roof is open, so nothing has to come apart later to add it.

Insulation follows the use of the building: blanket under trapezoidal sheet for most warehouses, rigid board where the deck must carry traffic, and insulated panel systems where the thermal envelope and the finished surface are one product. Vapour control layers and foil facings are lapped and taped to the drawing so the barrier is continuous rather than approximately in place. Deliveries are timed with the sheeting crew so the material spends the minimum time open to the weather.

Rain and heat both drive the programme. We monitor forecasts, keep sheeting inside the dry window and stop work when a wet or hot surface cannot be safely worked. Bays are completed and closed one at a time, so a sudden shower never finds an open building.

Crews above ground work under fall protection. Where fall protection systems are already installed on the roof, we use them and keep clear of lifeline routes; where they are not, temporary edge protection goes up before the first sheet.

Communication runs daily: the crew reports what closed, what is open and what the forecast means for tomorrow, so your operations team knows which bay will be dry tonight. Fixings are driven to the manufacturer's torque rather than by feel, and a fastener that starts to spin — a sign it has lost its grip — is replaced and recorded. Sealant waits for dry, clean surfaces, because a line laid on damp or dusty metal is the leak you find in the first storm.

Handover includes water testing of completed areas, the as-built sheet layout, a penetration register and supplier warranty documents where the specification provides for them. Your facilities team receives a maintenance checklist: gutter clearing, a fastener re-torque schedule and inspection points ahead of storm season.

After handover, repairs and inspections run through field maintenance, so small defects are caught before they become leaks. Send your roof drawings and we will walk the scope with you.
