What We Deliver
Roof Refurbishment & Re-Covering
Planned refurbishment of ageing roofs: strip and re-cover, overlays and insulation upgrades, sequenced to keep buildings watertight and operational throughout the works.
New-Build Roofing Packages
Design coordination, specification, installation and warranty handover on new-build and extension schemes, working to the main contractor’s programme and quality plan.
Flat Roofing & Waterproofing Systems
Single-ply membranes, liquid-applied waterproofing, hot melt and built-up felt, installed by manufacturer-approved operatives with manufacturer-backed warranties where specified.
Surveys, Condition Reports & Planned Maintenance
Drone and access-based roof surveys, NFRC Competent Person Scheme reports and planned maintenance programmes that give estates and facilities teams a clear view of their roof assets.
Industrial & Agricultural Roofing
Roof replacements and re-roofing for farms, estates, warehouses and industrial units, including metal profile roofs and roofs prepared for solar PV, planned around working sites.
Roofing & Solar PV Together
Roof covering, fixings and solar array designed and installed by one contractor, so structural checks, waterproofing details and warranties are coordinated rather than compromised.
How We Work
Occupied Buildings
Phased programmes, segregated access, noise and dust control and daily communication with site and estates teams keep buildings operational during the works.
Main-Contractor Packages
Clear scope and exclusions, programme certainty, RAMS and coordinated design information, with attendance at progress meetings as part of your supply chain.
Compliance & Handover
ISO 9001, 14001 and 45001 management systems, CHAS, Constructionline Gold and SafeContractor accreditation, with O&M information, warranties and photographic records at handover.
