Plymouth gives a roofer two cities in one. The centre was rebuilt after wartime destruction on a new plan, which left a large stock of 1950s and 1960s buildings with flat and very low-pitch roofs — shops, offices, blocks of flats, schools and civic buildings covered in felt, asphalt and later single-ply. Around it stand the surviving Victorian and Edwardian suburbs, terraced and slated on steep pitches, climbing the hills above the Sound. The trade moves between the two all week.
The exposure follows the covering. Flat roofs mean heat: torch-on, bitumen, hot-air welding, on buildings that are occupied underneath and full of stock, equipment or people. That is the fire claim, and it is almost always decided on whether the permit and the fire watch were actually done rather than on how well the detail was laid. Slate means wind: Plymouth sits open to the south-west, takes Atlantic gales and salt air off the Sound, and anything not properly fixed on an exposed pitch will find the street eventually.
Add hills steep enough that scaffold bases and vehicle parking are a design problem in themselves, and a coastal atmosphere that eats fixings, flashings and fastenings faster than an inland one, and you have a roofing risk that needs explaining to an underwriter rather than ticking through a portal. Apex is a Bristol-based commercial broker and does that explaining for you.
Underwriters treat flat roofing and pitched slating as different risks, and Plymouth gives you both in quantity. Being explicit about the split is one of the most useful things you can put on a proposal.
South-westerly gales. Plymouth is exposed to Atlantic weather coming straight up the Sound. Wind uplift on flat-roof membranes, temporary coverings, stacked materials and sheeting is a live, seasonal risk rather than an occasional one. Perimeter fixing, ballast and how you leave a roof on a Friday are the things that decide whether Monday brings a claim.
Salt-laden air. coastal atmosphere corrodes fixings, fastenings, flashings and metalwork faster than it does inland. Roofs closer to the water need specification that allows for it, and premature corrosion is a recurring source of callbacks and of disputes about whether the failure was workmanship or environment.
Heat over occupied buildings. the defining Plymouth flat-roof exposure is torch and hot-air work above shops, flats, schools and offices that are open underneath you. A smouldering fire that shows itself two hours after you leave is the classic hot-works loss, and it is why the permit and the fire watch are conditions rather than suggestions.
The Work at Height Regulations 2005 apply to all of it, and on large flat roofs the edge-protection and fragile-surface planning is what an investigation examines.
Hot-works permits and a fire-watch period after completion are standard insurer conditions on torch-on, bitumen and hot-air work, and in most wordings they are conditions precedent to liability.
CDM 2015 duties apply on larger contracts, including refurbishment programmes on schools, blocks and public buildings where you may hold contractor or principal-contractor status.
Fire-safety duties on occupied buildings mean the responsible person for the premises has obligations too; expect a formal permit system, isolation of alarms and a documented handback on commercial sites.
Asbestos is common in older flat-roof build-ups, bitumen products and cement sheeting from the post-war period; know what is licensable before anything is cut or lifted.
A torch-on repair over an occupied shop ignites the deck or insulation and the fire is discovered after you have left — a hot-works claim, and the permit and fire-watch records decide it.
Wind lifts a partly fixed membrane or a temporary covering off a flat roof overnight and it damages vehicles and neighbouring property — public liability, and contract works for your own work.
A slate comes off an exposed pitch on a sloping street and injures a passer-by or damages a parked car — public liability responds.
Water enters a school or a block of flats through a roof opened up for refurbishment — third-party damage and, on a commercial building, a possible business interruption claim behind it.
An employee falls through a fragile rooflight on a large industrial roof — employers’ liability responds, with RIDDOR reporting and an HSE investigation into the planning.
Height and heat put roofing in the highest-hazard group, and many insurers decline the trade before looking at the individual firm. It is a market problem rather than a judgement on you. We place roofing with insurers who write it on purpose and understand the difference between a flat-roof contractor and a domestic slater.
Yes, and for a Plymouth flat-roofing business it is the central question. It is written subject to conditions — a hot-works permit and a fire watch for a stated period after you finish, usually with a documented handback on commercial premises. We check the wording against the buildings you actually work over rather than an empty site.
On refurbishment contracts for schools, blocks and public buildings you may carry contractor or principal-contractor duties under CDM 2015. Your liability cover should reflect the role you have accepted, so tell us when it changes.
Gas kit, hot-air welders, ladders, towers and hand tools can be covered against theft from site, van or premises, subject to the security and overnight-storage conditions in the policy.
Yes — legally required if you employ anyone, including labour-only sub-contractors, which covers nearly all crewed flat-roofing and commercial work.
It changes the arguments more than the covers. Salt air corrodes fixings and metalwork faster and Atlantic wind loads exposed roofs harder, so premature failure and storm damage come up more often here than inland — and with them the question of whether a failure was workmanship, specification or weather. That is why we look carefully at how your policy treats defective workmanship, contract works and any design element you have taken on.
Tell us about your business and we’ll place it on the specialist market — or leave your number and a named broker calls you back, usually the same working day.
