Roofing in Portishead
Portishead is part of the North Somerset patch Jon covers from Weston-super-Mare — and you deal with him directly, start to finish.
Whether your home is one of the town’s older properties or a much newer house, the approach is the same: look at the roof properly, explain what’s going on in plain terms, and quote for the work it genuinely needs.
Jon has more than 30 years of hands-on roofing experience. Slate is his specialism, and he works with all types of tile, flat roofs, leadwork and rooflines.
Services
The main jobs Jon carries out for Portishead homeowners.

Slipped or cracked tiles, damaged slates, failed flashing and leaks. Jon finds where the water is actually getting in and fixes the cause, not just the symptom.
Roof repairs
When repairs no longer make sense, a full re-roof in slate or tile, with new felt and battens where required.
Roof replacements
Repairs and maintenance for flat-roofed extensions, garages and dormers — and a straight answer when one needs replacing.
Flat roofingPortishead properties
Portishead has grown a great deal in recent decades, so roofs around the town vary more than in most places.
Many of the town’s newer houses have concrete interlocking tiles, often with dry-fixed ridges and verges. Typical jobs include replacing cracked or slipped tiles, re-securing loose ridge or verge pieces, and sorting leaks around roof windows and soil pipes.
The older parts of Portishead have Victorian and Edwardian houses where slate roofs, chimneys and leadwork are more common — and slate is Jon’s specialism.
Extensions, garages and dormers with flat roofs need regular attention. Ponding water, splits and failed edges are the usual culprits when they start to leak.
Facing the Severn Estuary, Portishead gets its share of strong winds and driving rain, which tests ridge tiles, flashing and gutters.
Roof maintenance
You don’t need to go up a ladder to spot most early warning signs. A few minutes from the garden and the loft can save a bigger bill later.
After a windy spell, check for slipped, cracked or missing tiles and slates, and anything sitting in the gutters that shouldn’t be.
Water spilling over the edge usually means a blockage or a joint that has failed — and that water ends up in walls and the roof edge.
Look for damp patches on the timbers or felt, drips, or daylight coming through. Note where they are; it helps pinpoint the problem.
Lead flashing that has lifted or split where the chimney meets the roof is one of the most common causes of leaks.
Puddles that are still there a couple of days later suggest a drainage or falls problem worth looking at.
Please don’t go up on the roof yourself. If you spot something, call Jon on 07429 335555.
