What you get with Eco Roofers
What we typically see on West Yorkshire roofs
West Yorkshire roof-stock is dominated by stone-slate and Welsh slate on Victorian and Edwardian terrace stock through Leeds (LS6/7/8), Bradford (BD1/7/8/9), Halifax, and Huddersfield. Stone-slate match is the single most-common heritage re-roof job here.
Local weather notes. Pennine wet-Atlantic weather — moss growth, valley leaks, and lead-flashing failure are recurring problems on older stock.
Approved Document L 2022 sets the thermal performance baseline for new roofs (U ≤ 0.16 W/m²K pitched, ≤ 0.18 flat). On flat roofs, BS 6229:2018 sets the design and falls standard. Eco Roofers will guide you through any Building Control notification needed on your job.

More questions answered
What’s wrong with cold roofs?
Cold-roof construction has insulation under the deck, leaving the deck cold. Warm moist internal air condenses on the cold deck, causing damp, mould, and structural rot.
How is warm-roof retrofit done?
Strip existing membrane and insulation. Lay vapour control layer over deck. Install 100-150mm PIR insulation above deck. New membrane (typically EPDM) on top. New edge trim and outlets.
How long does it take?
2-4 days for typical 20m² extension. £2,400-£4,500 fully fitted including 10-year installation guarantee.
