Most commercial roof leaks come from blocked outlets causing ponding water, splits in the membrane at joints or upstands, and failed flashing details around rooflights, parapets and roof penetrations. A roof survey identifies the exact source before any repair work is quoted.

We aim to attend emergency industrial roof repairs within 24 hours of being contacted, and sooner where a roof is letting in significant amounts of water or stock and equipment are at risk. The first visit focuses on making the roof watertight with a temporary repair before planning a permanent fix.

A commercial roof survey involves a visual inspection of the roof covering, flashings, rooflights, drainage outlets and insulation, along with photographs and a written condition report rating each element. The report sets out whether the roof needs maintenance, repair or replacement and gives a guide to remaining lifespan.

Commercial roof repair costs in the UK typically range between £300 and £3,000 for localised repairs such as a membrane patch or flashing renewal, while larger sections of recovering can cost between £40 and £150 per square metre depending on the system. A survey is the only way to confirm an accurate figure for your building.

Industrial roofing contractors work to larger roof areas, taller access requirements and stricter site safety procedures than general roofers, including risk assessments and method statements in line with the Construction Design and Management Regulations 2015, permits to work and coordination with other contractors on site. The roofing systems used, such as standing seam metal and built up felt, are also more commonly specified on industrial buildings.

Flat roof installation involves removing any existing covering down to the deck, checking and renewing the timber or concrete structure where needed, fitting insulation to meet Building Regulations Part L, then installing the chosen membrane such as EPDM, single ply or GRP fibreglass with all upstands, edge trims and outlets detailed to manufacturer specifications.

When looking for flat roofing contractors near you, check for evidence of public liability insurance, CSCS cards for the operatives, examples of completed flat roofs and a willingness to provide a written quotation after a site visit rather than a price over the phone.

A flat roof specialist has specific training and experience in welding or bonding membranes such as EPDM, PVC, TPO and GRP, understands how falls and tapered insulation are used to manage drainage, and is familiar with the detailing around upstands, outlets and rooflights where flat roofs most often fail.

A flat roof is made waterproof by installing a continuous membrane, such as EPDM rubber, single ply PVC or TPO, or a GRP fibreglass laminate, with all joints welded or bonded and all edges, upstands and penetrations finished with matching trims and flashings so there is no break in the waterproof layer.

Pitched roof installation involves forming or checking the roof structure, fitting breathable roofing felt and battens, then installing the chosen covering, most commonly concrete or clay tiles, natural slate or interlocking tiles, fixed in line with BS 5534, which sets out mechanical fixing requirements based on location, height and exposure.

A new pitched roof in the UK typically costs between £70 and £200 per square metre depending on whether concrete tiles, clay tiles or natural slate are specified, with natural slate at the higher end of that range due to material and labour costs.

A ridge tile needs replacing when the mortar bedding has cracked or fallen away, when the tile itself is cracked or slipping, or when dry ridge fixing components have failed, since a loose ridge tile can let water into the roof space and is also a falling hazard.

A pitched roof replacement typically takes between 1 and 2 weeks for an average house, including stripping the existing covering, renewing the underlay and battens, and installing the new tiles or slates, with additional time if the timber structure needs repair.

Guttering installation involves fitting new gutter sections, brackets and downpipes at the correct fall to carry rainwater away from the roof to the drainage system, with joints sealed and outlets positioned to avoid overflow during heavy rain.

Fascias and soffits need replacing when the timber has rotted, when uPVC boards have cracked or discoloured beyond cleaning, or when they no longer provide a secure fixing point for the guttering, since damaged fascias can allow water and pests into the roof void.

Fixing a leaking gutter typically costs between £80 and £250 for a section repair or reseal, while replacing a full run of guttering on an average house costs between £600 and £1,500 depending on the length and the material chosen.

uPVC fascia board installation involves removing the existing timber fascia and soffit boards and fitting low maintenance uPVC boards in their place, along with new guttering brackets, to give a weatherproof finish that does not need painting.

Gutters should be cleared at least once a year, typically in autumn after leaves have fallen, and more often if the property is near trees, since blocked gutters cause water to overflow down walls and can lead to damp and, in some cases, roof leaks at the eaves.

A roof inspection service includes a visual check of the roof covering, flashings, ridge and verge details, guttering and any rooflights, along with photographs and a written report identifying any defects, their urgency and an estimate of remaining roof life.

A roof maintenance contract is an agreement for regular inspections and minor repairs, usually carried out once or twice a year, and is most useful for commercial and industrial property owners who need to manage roof condition proactively and avoid unexpected leaks affecting their business.

A roof health check, sometimes called a roof survey, typically costs between £150 and £400 depending on the size and access requirements of the roof, and is often credited against the cost of any repair work carried out afterwards.

An annual roof inspection checklist should cover the condition of the roof covering, the state of flashings and seals around chimneys and rooflights, the condition of ridge and verge details, whether gutters and downpipes are clear and securely fixed, and any signs of damp or staining on ceilings below the roof.
