Extension Roof Installation & Replacement in Sunderland
Single-storey extension roofs are usually flat or low-pitch GRP, EPDM or warm-deck systems. Building Control wants U-values demonstrated, falls right, and the upstand against the existing wall properly flashed. We handle all of it — including the as-built paperwork. We're regularly on roofs close to the A19, out around Sunderland Enterprise Park, through Roker and Fulwell.
- Warm-deck builds with full U-value compliance
- GRP, EPDM and liquid system options
- Insulated PIR boards laid to falls
- Lead or proprietary flashing into existing brickwork
- Sign-off paperwork supplied for Building Control

Extension Roof FAQs
Do I need warm deck or cold deck?+
Modern Building Regs effectively require warm deck for new extensions — insulation above the deck, no cold cavity, no condensation risk. We won't build a cold deck unless there's a specific structural reason.
Can you co-ordinate with my builder?+
Yes — we work alongside main contractors weekly. Programme is set in advance, not on the fly.
