Is it worth repairing an old slate roof?

Often, yes. Welsh slate outlives its fixings, so slipped slates are cheap repairs at £150 to £450, and even a full strip can reuse sound slates on new battens and felt. Replacement only wins when the slates themselves are delaminating.

What is the difference between Welsh and Spanish slate?

Welsh slate is the premium material with a century-plus track record. Spanish slate looks close at a lower price but quality varies by quarry; ask which quarry and what warranty. Fibre-cement slate is the budget alternative.

Can you match tiles on my 1930s semi?

Almost always. Common interlocking profiles are still made, and discontinued ones are matched from reclaim stock, so repairs and extensions blend into the existing roof.

What are dry ridge and dry verge systems?

Mechanically fixed ridge and verge systems that clip and screw instead of relying on mortar. On exposed coastal plots they outlast mortar by years, because there is nothing for the wind to crack and lift.

Do I need planning permission to re-roof?

Like-for-like re-roofing needs no permission. Conservation areas such as Saltburn can require natural slate and traditional details, and changing the roof covering's weight or profile can trigger building regs, a proper quote flags both.

Two roofscapes, one town

Teesside has two great roofing traditions side by side. The Victorian and Edwardian terraces of Middlesbrough, Saltburn, Norton and Hartlepool's older streets carry Welsh slate, much of it original, a material that can outlive the nails holding it by half a century. The inter-war semis and post-war estates carry concrete interlocking tiles, tough and cheap to cover, but sitting on underlay that was never designed to last this long.

Each needs its own approach. Slate work is about fixings and matching: replacing slipped slates with properly sized reclaimed Welsh slate, or stripping and re-roofing with the good slates reused. Tile work is usually about what is underneath: the tiles come off looking fine, and the perished felt and tired battens are the real job.

Slate: repair, reuse or replace

Natural slate is the one covering where repair genuinely competes with replacement. Individual slipped slates are a quick fix, typically £150 to £450 depending on access. When nail fatigue spreads across the roof, a strip and re-slate reusing the sound slates keeps the period look at a lower cost than new slate, and a good survey will tell you honestly what percentage of your roof is worth saving. New Welsh slate is the premium option; Spanish slate and fibre-cement alternatives bring the cost down with a close visual match, though quality varies and is worth asking about specifically.

Tiles: concrete, clay and modern profiles

Concrete interlocking tiles are the value workhorse and suit the bulk of Teesside's 20th-century housing. Clay tiles, including the rosemary reds on older properties, cost more and reward it with colour that never fades. On the exposed coast at Redcar and Saltburn, dry ridge and dry verge systems are worth specifying: mechanically fixed instead of mortared, they remove the weak point the North Sea wind finds first. Matching discontinued profiles on older roofs is routine, reclaim stock covers most of what Teesside's housing stock throws up.

What quotes should specify

Covering by make and profile, underlay type (breathable membrane as standard), batten treatment, fixing method (nails and clips rated for the exposure), ridge and verge system, and how valleys and abutments will be formed. If a quote just says "new roof tiles", it is not a quote, it is a guess. Typical figures are in the cost guide, and the repair-versus-replace call is in the repair or re-roof guide.
