📞 Call Now: 0239 307 1334Drayton is a suburb of Cosham sharing the same 1930s semi-detached housing profile. Concrete plain tiles on 1930s stock, now approaching 90 years — among the oldest concrete tile roofs in the Portsmouth area.
Drayton sits just at the northern edge of Portsea Island before the creek crossing. The creek creates a humidity corridor that affects northern edge properties. Similar frost profile to Cosham.
1930s concrete plain tile erosion — the dominant issue. Many Drayton properties are on their second set of concrete tiles approaching the decision point for a third re-roof. Ridge mortar failure. Moss growth from creek humidity.
Drayton's concentration of some of the oldest concrete tile roofs in the Portsmouth area means we regularly advise on the re-roof versus continued repair question. The honest answer for most 1930s Drayton properties is that they are at or past the economic repair threshold.
"1930s semi in Drayton — on our second concrete tile roof and tiles were eroding again. Portsmouth Roofing recommended modern concrete interlocking as the final answer. Exactly right."
"Ridge mortar replacement — used the right mortar mix for the age of the property."
"Moss treatment on heavily shaded north-facing slope. Soft-wash only. Gutters cleared."
Most Portsmouth roof problems announce themselves as a damp patch, a slipped tile visible from the street, or debris in the gutter after a storm — not as a dramatic failure.
When it is not the answer: If more than a third of the covering has failed or nail sickness affects several slopes, repairing tile-by-tile is money wasted Read the full guide.
Solent salt air and exposed Channel weather corrode fixings and lift tiles faster than inland Hampshire. Portsea Island's dense Victorian terraces mean rear elevations are often reached only through tight alleys, and front scaffold needs permit-controlled pavement space. It is why we specify marine-grade fixings and correct lead codes as standard on Portsmouth roofs — the coastal environment punishes anything less.
We inspect the roof, trace the actual fault — often metres from the visible stain — and check the wider covering and fixings.
You get an itemised quote separating investigation, access and repair, with coastal-grade materials specified.
We book a slot and arrange any scaffold or tower access in advance.
We carry out the repair with marine-grade stainless fixings and flexible ridge compound, not sand-cement.
We clear debris, walk you through what was done, and issue the written 10-year workmanship guarantee.
| Job | Typical duration |
|---|---|
| Slipped or cracked tiles (up to 5) | 1–2 hours |
| Leak diagnosis & repair | Half a day |
| Chimney flashing renewal | Half to full day |
| Rear valley rebuild | 2–3 days |
| Nail-sickness re-fix (per slope) | 1–2 days |
Wet or high-wind days pause tiling and lead work — we build weather margin into every Portsmouth booking.
Most repairs run from towers or roof ladders; scaffold is quoted only where the job needs safe standing time at height. Scaffold is specified for: chimney-side repairs, full valley rebuilds, and anything beyond a day at height on a two-storey terrace - always itemised in your written quote, never a hidden extra, and we arrange it.
Portsea Island's dense Victorian terraces mean rear elevations are often reached only through tight alleys, and front scaffold needs permit-controlled pavement space. Pavement scaffold and skip permits go through Portsmouth City Council; allow a few working days on streets like Albert Road, Fawcett Road, Marmion Road where space is tight.
