COMMERCIAL ROOFING SERVICES
At Jim Williams Roofing Ltd, we provide commercial roofing services for agricultural, industrial, and commercial customers across Pembrokeshire and West Wales – from Haverfordwest and Pembroke Dock to Milford Haven, Fishguard, and the rural areas in between. With over 40 years in the trade, we handle roofing work on buildings of all sizes, from routine maintenance and urgent repairs through to full installation.
Commercial roofing brings its own pressures. Downtime costs money, access can be complicated, and work often needs to happen alongside normal site activity. We manage our roofing work to keep operations moving and avoid unnecessary disruption.
Commercial roofing problems we deal with
We handle all commercial and agricultural roofing problems, such as:
Leaks or water ingress
Storm or weather damage
Deteriorating sheeted or metal roofing
Failing flat roofing systems
Roofs nearing the end of their service life
Work required for new builds or extensions
Ongoing maintenance issues on exposed buildings
We provide clear scopes of work and written quotations so you can plan accordingly.

How we manage roofing work on active commercial sites
Many commercial and agricultural buildings need to remain operational while roofing work is carried out. We plan for this from the outset.
Including:
- Sequencing work to reduce disruption
- Managing safe access
- Coordinating with other contractors on site
- Keeping work moving to agreed timescales
We plan the work to minimise downtime and avoid unnecessary interruption, whatever the size of the project.
Giving you the best solutions for your building
Every commercial roofing project is unique. We don’t assume one approach fits every situation. On some buildings, a well-judged repair is the right answer. On others, a full replacement or new roof makes more sense.
Our experienced team looks at everything from the current roof condition and what the building needs to function properly, to building aesthetics. We give you options that balance performance, longevity, appearance, and budget, whether the work involves targeted repairs, upgrading part of a roof, or installing a new one.
