We’re Specialist Contractors in Commercial Flat & Pitched Roofing Systems
DH Roofing Ltd delivers roof refurbishment and full re-roofing solutions for commercial, industrial and public-sector buildings. We help you extend the life of your roof, improve performance, and reduce ongoing risk — all delivered with robust health & safety and quality control procedures. Where required, we install to manufacturer-approved methods and can provide warranties on completion.
Whether we’re restoring an ageing flat roof, stripping and replacing a pitched roof covering, or over-cladding an operational industrial building with minimal disruption, we provide a fully managed service from survey through to handover documentation.
Refurbishment & Re-Roofing
Do You Need Refurbishment or Full Replacement?
Not every roof needs a full replacement. We’ll help you make the right decision based on condition, compliance and lifecycle value — supported by professional reporting and clear recommendations.
Depending on what we find, we can deliver:
- Targeted repairs and detailing upgrades to extend service life
- Refurbishment overlays (often ideal for many flat roof systems)
- Strip & re-cover / full re-roofing where deterioration is advanced
- Over-cladding solutions to improve insulation and weatherproofing with reduced disruption
Refurbishment & Re-Roofing
Commercial Flat Roof Refurbishment
We refurbish commercial flat roofs using high-performance systems suited to live, occupied environments — focusing on long-term waterproofing integrity, thermal upgrades and durability.
Our flat roof refurbishment work can include:
- Cold-applied liquid waterproofing overlays to create seamless detailing around penetrations and complex interfaces (often ideal where hot works are restricted)
- Reinforced bituminous membrane refurbishments, including warm-roof build-ups with vapour control and insulation layers (installed to recognised technical standards)
- Cut-to-falls and insulation upgrades to improve drainage performance and help support Part L compliance
Refurbishment & Re-Roofing
Pitched Roof Re-Roofing and Refurbishment
We carry out pitched roof re-roofing and refurbishment across a wide range of building types. Our work includes tiling, slating and specialist leadwork detailing, delivered in line with the relevant British Standards and NHBC technical requirements.
Our pitched roof services include:
- Tile and slate strip & re-cover, including full detailing to eaves, ridges, hips, verges, valleys and abutments
- Ventilation and underlay design to support effective condensation control
- Leadwork and flashings installed in accordance with Lead Sheet Association guidance by trained operatives
Where required, we support projects with in-house carpentry to complete structural repairs, strengthening works and roof preparation prior to re-roofing.
Refurbishment & Re-Roofing
Over-Cladding and Industrial Roof Replacement
For ageing industrial roofs, we provide re-roofing and over-cladding solutions designed to improve insulation, enhance weatherproofing and extend roof life — often while you remain operational.
Where required, we can also incorporate asbestos roof replacement as part of a controlled, compliant refurbishment programme.
Refurbishment & Re-Roofing
Our Survey-Led, Safety-Focused Delivery
Every refurbishment or re-roofing project we deliver starts with understanding the roof’s condition and risks. Our surveys can include inspections, moisture mapping, drone imagery and written reporting to support specification and lifecycle planning.
We manage works with clear site controls, including RAMS and completion records (such as photographic QA) to support handover and compliance.
If you need safe access once works are complete, we can also integrate roof safety and fall protection systems aligned to Work at Height requirements.
