Flat Roof Installation
Roof Renovations LTD installs robust, weatherproof flat roofs using proven membranes—EPDM, GRP and torch-on systems—selected to suit the building and budget. Our approach focuses on correct falls, upstands, outlets and insulation so the roof performs for years with minimal maintenance. Federation-certified fitters with 28 years' experience carry out every job to professional standards, keeping sites tidy and projects on schedule across South Wales.

How It Works
Site Survey & Specification
We carry out a measured site survey, inspect substrate, falls and outlets, and produce a written specification detailing membrane type, insulation and flashing required.
Material Selection & Planning
You choose from industry-standard systems (EPDM, GRP, torch-on) and we plan sequencing, access, scaffolding and drainage to meet Building Regs and best practice.
Install, Detail & Handover
Our fitters install vapour control, insulation, membrane and flashings, finish outlets and upstands, clear the site and provide care notes and a post-install inspection.

Why Choose us for Flat Roof Installation?
Built for Long-Term Performance
We specify correct falls, insulation and upstands, and use proven membranes to avoid ponding and leaks — delivering roofs that stay watertight for years.
Federation-Certified Experience
With 28 years in the trade and Federation certification, our teams bring technical know-how and disciplined workmanship to every flat roof installation.
Punctual, Tidy and Professional
We set realistic start dates, maintain tidy work areas, protect gardens and driveways, and leave the property clean with clear documentation on completion.
Technical approach: Flat roof longevity comes from correct detailing. We install a suitable vapour control layer, thermal insulation sized to current standards, and ensure falls to outlets or gullies to prevent ponding. Membrane choice depends on substrate and use — EPDM for reliable rubber membranes on domestic garages and extensions, GRP for smooth, seamless finishes with rapid cure, and torch-on felt for pitched-to-flat transitions. Flashings, upstands, leadwork or proprietary trims are fitted to all junctions and chimneys so the roof ties into existing fabric correctly.
We work across South Wales — from Cardiff terraces to modern homes in Bridgeend — and build roofs to current Building Regulations and industry best practice. Jobs are scheduled to minimise disruption, with on-site protection for gutters, patios and planting. As a Federation-certified contractor with 28 years of experience, Roof Renovations LTD provides clear quotations, reliable start dates and tidy, professional handovers including care instructions and a follow-up inspection.
