Slating and Tiling
Our slating and tiling services combine traditional craftsmanship with modern techniques to create durable, weather-resistant roofs. We use premium materials like Welsh Penrhyn slate and offer bespoke solutions for heritage and contemporary properties. Each installation includes expert guidance on material selection and design options.
Leadwork
Specialist leadwork services for gutters, valleys, and architectural details ensure watertight integrity. Our skilled technicians handle complex installations and repairs, maintaining compliance with building regulations while preserving aesthetic appeal for historic and modern buildings.
Loft Extensions
Transform your loft into functional living space with our comprehensive extension service. We handle structural modifications, insulation, and access solutions while ensuring compliance with planning requirements and building standards for safe, habitable spaces.
Liquid Plastic
Advanced liquid plastic roofing systems provide seamless, waterproof solutions for flat and low-pitch roofs. This cold-applied system offers rapid installation with minimal disruption, ideal for both new builds and refurbishment projects requiring durable, maintenance-free coverings.
Roof Reports
Comprehensive roof condition assessments identify potential issues and maintenance needs. Our detailed reports include photographic evidence and prioritised recommendations, helping property owners make informed decisions about repairs, replacements, or upgrades.

GWS replaced our entire roof and we are very happy with the end result. The roofers were polite and friendly, the supervisor always kept us up-to-date on the status of the project and was easy to get in touch with, and the pricing was clear. I was very happy with their service throughout the process! Services: Roof installation, Skylight repair

Report
New roof terrace and new French doors. Very good job, thoroughly professional throughout. Great attention to detail. Every aspect of the job was good, from comprehensive quotes through to completion, very professional and competent staff, always turned up on time, very hard working, as unobtrusive as possible, and all very likeable. Always left the site tidy at the end of each day. Responded promptly to any queries as they arose. Good also to see that health and safety were very important throughout the job & to see that staff retention was good, always a good sign. If only all home maintenance work could be like this.
