— Our Process
How It Works
Survey & Practical Quote
We inspect the garage roof, structure and gutters on site, identify required alterations (ties, upstands, falls) and provide a clear, written quote with timescales.
Roof Alterations & Waterproofing
We carry out roof raising/tie-in, re‑roofing, leadwork or flat‑roof systems (GRP/EPDM/torch) plus insulation and vapour control to meet Building Regulations.
Finish, Check & Leave Tidy
We complete external detailing, connect rainwater goods and flashings, carry out waterproofing tests where needed and leave the site clean with a handover checklist.

Why Choose us for Garage Conversion?
Decades of Roofing Expertise
28 years focused on roofs means we understand ties, rafters, trusses and flat‑roof falls so the conversion is structurally sound and long‑lasting.
Punctual, Organised Trade Operatives
We work to agreed start dates, keep the programme tight and coordinate with builders or electricians to reduce disruption on site.
Watertight Work & Tidy Site Standards
High‑quality leadwork, flashings and modern waterproof membranes ensure a dry conversion; we clear debris daily and hand back a tidy property.
Roof‑first approach to garage conversions. Many failed conversions start with inadequate roof works: poor upstands, incorrect falls or missing vapour control lead to leaks and damp. We specialise in the roofing and external building envelope for conversions — from sloping roof tie‑ins and re‑tiling to flat‑roof replacements using GRP, EPDM or hot‑applied systems. We install proper insulation, ventilation and vapour barriers so the room performs year‑round.
What we handle on every garage conversion:
- Survey of roof structure, guttering and verge/soffit details
- Roof raising, rafter/joist alterations and lead flashings
- New flat‑roof systems with tapered insulation and outlets
- Waterproofing tests, new rainwater connections and external finishes
Working across South Wales including Cardiff and Bridgeend, we ensure the roofing elements meet Building Regulations and coordinate with your builder or local inspector to keep your conversion compliant and watertight.

Frequently Asked Questions
Most single‑storey garage conversions are permitted development, but there are exceptions—especially in conservation areas or if you alter the roofline significantly. We advise on likely requirements during the survey and can work with your builder or planning agent if further permissions are needed.
