Full roof replacement in Cosham with marine-grade fixings and 10-year guarantee. Cosham's 1930s semi stock often has roofs that have been re-tiled once before — the structural condition of the ridge and hip timbers is critical to assess before specifying the replacement tile and batten. Written survey, itemised quote before we lift a tile.
Every Cosham re-roof survey includes batten and rafter condition assessment, tile identification for heritage matching where required, and fixing specification for the coastal exposure zone.
Full strip, breathable membrane, pressure-treated battens, marine-grade stainless ring-shank fixings as standard. Scaffold included in the quote. Written 10-year guarantee on completion.
Standard galvanised fixings have a reduced design life in Cosham's coastal-adjacent environment. Marine-grade stainless is specified as standard on all our Cosham re-roofs at modest additional cost for a 20-plus-year life difference.
Cosham's housing stock creates a specific re-roof specification profile. Cosham's 1930s semi stock often has roofs that have been re-tiled once before — the structural condition of the ridge and hip timbers is critical to assess before specifying the replacement tile and batten. We survey the full batten and rafter structure before quoting — any deck or structural issues are identified upfront and included in the price, not presented as mid-job extras.
Every Cosham re-roof includes full strip of existing tiles and underlay, structural assessment of battens and rafters, installation of breathable membrane underlay, pressure-treated battens, and marine-grade stainless fixings as standard. Scaffold is included in the quote — we do not carry out re-roof work without proper access.
Cosham is within the island coastal zone for fixing specification. Marine-grade stainless is standard on all Cosham re-roofs. We specify marine-grade stainless fixings on all our Portsmouth area re-roofs as standard — not as an optional extra. The additional cost over standard galvanised is modest; the difference in design life in this environment is 20-30 years.

"1930s semi on Drayton Lane — re-roof the second time for this property. Portsmouth Roofing was honest that the tiles were past repair and specified the right modern equivalent. No pressure, good advice."
"Nail sickness on our post-war Cosham property. Both main slopes assessed and re-fixed with stainless. Explained exactly what nail sickness means and what to watch for."
"Flat roof on our 1970s rear extension — GRP in a day. They matched the upstand height to the existing brickwork exactly. Neat finish."
