Is Loft Conversion Roofing the Right Fix?
A full re-roof is the right call when repairs keep recurring, nail sickness affects multiple slopes, or the covering has reached the end of its life for its type.
- Repeated repairs to the same roof within a few years
- Multiple slopes showing slipped tiles from nail sickness
- Concrete tiles visibly eroded and shedding aggregate
- Sagging roofline or visible dips between rafters
- A roof at or past its expected age — 35–50 years for concrete tile
When it is not the answer: If the tiles are sound but the fixings have failed, a strip-and-relay re-fix costs far less than a full replacement Read the full guide.
Local Factors in Cosham
Portsdown Hill shelter reduces salt slightly, but 1930s concrete tiles here are shedding surface aggregate at 85–90 years old. Cosham's 1930s semis have generous simple roofs with good access, though mature avenue trees complicate scaffold and skip placement. It is why we specify marine-grade fixings and correct lead codes as standard on Cosham roofs — the coastal environment punishes anything less.

Getting Safely onto Cosham Roofs
A full re-roof always needs scaffold to every elevation for safe working and materials handling. Scaffold is specified for: the full duration of any re-roof — it is included and itemised in the quote, never a hidden extra - always itemised in your written quote, never a hidden extra, and we arrange it.

Pavement scaffold and skip permits go through Portsmouth City Council; allow a few working days on streets like High Street, Wootton Street, Spur Road where space is tight.

Living Around the Work
A re-roof means a week or more of scaffold, skip and daily activity — we protect the garden and drive, keep the site tidy, and agree access and parking before we start. You do not need to stay home for external work - we just need power and access agreed in advance.
Re-roofs run through most of the year; we programme around forecast weather and stage the strip so the roof is never exposed to a wet night. Portsdown Hill shelter reduces salt slightly, but 1930s concrete tiles here are shedding surface aggregate at 85–90 years old.
