Roof Repairs in Cosham from £150. 1930s concrete plain tile erosion — the surface aggregate is shedding on most properties in this era, creating progressive porosity. We diagnose the actual cause, specify the correct materials for Cosham's conditions, and fix it with a written guarantee.
Ridge mortar failure, nail-sick tile loss and lead flashing deterioration are the dominant repair calls from Cosham. Housing stock age and coastal exposure dictate which failure presents first.
Every Cosham repair quote starts with a roof survey from the roof, not from the ground. Secondary damage and related failures are identified before quoting so the written price covers the complete job.
Marine-grade stainless fixings on all re-fixing work. Lead code matched to the exposure position. Lime mortar on Victorian and Edwardian properties. We specify for Cosham's actual conditions.
The roofing repair calls we receive from Cosham follow a consistent pattern driven by the area's housing stock and climate. 1930s concrete plain tile erosion — the surface aggregate is shedding on most properties in this era, creating progressive porosity. Nail sickness on post-war estate stock north of the A27. Flat roof failures on 1970s rear extension additions. These are the failures we diagnose and fix week in, week out — we carry the materials for the most common repairs on every van.
Every repair quote in Cosham starts with a roof survey — not a price-per-tile estimate from the ground. We get up and assess the full extent of the problem, not just the visible symptom. Hidden failures, secondary damage and related issues are all identified before quoting. The written quote covers the full job.
Cosham's 1930s semis with eroding concrete plain tiles are typically at the re-roof rather than repair decision point. We advise honestly on whether repair or replacement is the economically correct recommendation for each property. We specify the correct materials for local conditions on every job — not whatever is cheapest or easiest to source.

"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."

"Flat roof on our 1970s rear extension — GRP in a day. They matched the upstand height to the existing brickwork exactly. Neat finish."
