We look after roofs on industrial units, workshops, shops, offices and blocks of flats across Mullion and the rest of Mullion, TR12. That covers emergency repairs when a rooflight gives way in a storm, planned re-covers of tired sheet roofs, flat roof replacements on retail and residential buildings, and the regular maintenance that stops the emergency calls happening in the first place. We work for owner-occupiers, landlords, managing agents and facilities teams, and we provide the paperwork each of them needs.
Industrial and sheet roofs in Mullion
The trading estates and industrial units around Mullion are mostly roofed in profiled metal or fibre cement sheet, much of it twenty to forty years old. The problems are predictable:
- Failed rooflights. GRP rooflights go brittle and opaque with age and are the number one source of leaks on older units across Mullion, TR12. We replace them with modern triple-skin units that let light in and keep water out.
- Cut-edge corrosion. The exposed edges of metal sheets rust back from the laps and eaves. Caught early it's treated and sealed; left, the sheets need replacing.
- Loose and failed fixings that let water in at every screw hole and let sheets lift in wind.
- Gutter failures. Valley and boundary gutters that have rusted, split or lost their falls, which we line in GRP or EPDM to give a seamless, long-life gutter without replacing it.
- Asbestos cement sheets on older units, which we remove and replace with modern insulated sheets following the HSE procedure, with waste transfer notes supplied.
- Overlays. Where the existing sheets are sound but the roof needs insulating or weatherproofing, an over-roof system fits over the top without stripping, keeping the building trading underneath.
Flat roofs on commercial and residential buildings
Shops with flats above, offices, blocks of flats and community buildings across Mullion mostly have flat roofs, and most of those are felt or asphalt past their life. We replace them in EPDM, GRP or single-ply as the roof demands, as warm roofs with insulation to current standards, and we phase larger roofs so the building is never left open. See our EPDM and GRP pages for the systems.
Working around your business
A roofing job on a trading business in Mullion has to fit round the business, not the other way round. We plan early starts, weekend work where it helps, and phased re-covers that keep the building weathertight at the end of every day. Risk assessments and method statements are provided before we start, our public and employer's liability certificates come with every quote, and our team works with harnesses, edge protection and safety lines on sheet roofs. We'll agree access, parking and site rules with you before the first day.
Landlords, managing agents and portfolios
For blocks of flats and property portfolios across Mullion, TR12 we offer planned maintenance visits, typically annually or twice a year: gutters cleared, minor repairs done on the spot, and a photographic condition report on every roof so you can budget for the bigger items ahead of time rather than reacting to leaks and tenant complaints. One report per building, in a consistent format, with a recommended works list and indicative costs.
Roof surveys and condition reports
Buying or leasing a commercial building in Mullion? We survey the roof and give you a written report with photographs, a condition rating and costed recommendations, so the roof doesn't become an expensive surprise after completion. See our inspections and reports page.
Common commercial roof problems in Mullion and what they cost to ignore
A failed rooflight on a unit in Mullion lets in a bucket of water with every heavy shower; left for a winter it ruins stock, racking and the slab below, and the repair bill is the same as it would have been in September. Cut-edge corrosion treated early is a sealing job; left five years, it's new sheets. A blocked valley gutter on a trading estate roof in Mullion, TR12 overflows into the building at the lap joints, and because it's out of sight nobody notices until the ceiling tiles come down. The pattern is always the same: small, cheap problems become big, expensive ones because nobody looks at the roof. An annual inspection and gutter clear is the cheapest insurance a business in Mullion can buy.
Flats, HMOs and mixed-use buildings
The shops with flats above in the centre of Mullion and the converted houses let as flats across Mullion, TR12 have their own challenges: shared roofs with several leaseholders, tenants who report leaks late, and access through occupied flats. We're used to it. We coordinate with managing agents, give notice to tenants, work from external access wherever possible, and provide a report after every visit that can be shared with all the leaseholders so everyone can see what was done and what's coming.
Emergency response for businesses in Mullion
When a commercial roof in Mullion fails during trading hours, the priority is to protect people and stock and get the building safe. We attend the same day wherever possible, make the area below safe, carry out a temporary repair to stop the water, and give you a written note of what we found for your insurer or landlord that evening. The permanent repair is scheduled around your trading, with the materials ordered from the first visit so there's no second delay. For businesses across Mullion, TR12 on a maintenance agreement, emergency call-outs are prioritised and the visit cost is set in the agreement, so there's no negotiating in a crisis.
