“GRP replacement on our rear extension. Correct fall specification, no pooling. Done in one day.”
“They stripped the old felt and checked the deck before fitting new GRP. Found a soft section — replaced it transparently.”
“Free survey confirmed the fall was wrong on our extension. Correction included in the quote. Now drains correctly.”
Blowick's Norwood Avenue, Crowland Street and Chain Lane carry post-war estate housing from the 1952–1975 period — now at or approaching the maintenance inflection point. Concrete interlocking tile throughout. The highest concentration of simultaneous nail sickness and ridge mortar failure in the PR8 5 postcode is on streets built in the 1963–1972 window.
A flat roof survey assesses: existing covering condition, deck integrity (plywood, OSB or timber boards), drainage fall angle, outlet sizing, and any upstand or abutment details that require attention. Where the deck is soft or damaged we specify replacement as part of the quote — this is never added as a surprise on the day.
GRP fibreglass is our recommended specification for all coastal Southport flat roofs — seamless, 25-year design life, unaffected by coastal humidity. We laminate on site to the specific dimensions of your roof. The GRP topcoat is applied in appropriate weather conditions: above 5°C, dry, and with no rain forecast for 24 hours after application.
We confirm correct drainage fall on every flat roof installation. Flat roofs with insufficient fall pond water — the standing water accelerates membrane deterioration and, on GRP roofs, can lift the topcoat layer within 5–10 years. Fall is confirmed with a spirit level on completion. Call 01704 620 427 for a free flat roof survey.
GRP flat roof work is carried out year-round in dry conditions above 5°C. Most standard extension flat roofs are completed in one working day.
