Roofing in Paisley

Flashing is the metal detailing that seals joints — around chimneys, valleys, vents, skylights and wall junctions. These joints move and collect water flow, so flashing fails long before the main covering. If a roofer proposes reusing old flashing on a full replacement, push back.

Repair when damage is localised — a few slipped tiles, one flashing leak — and the roof is under about two-thirds of its expected life. Replace when leaks recur in different places, more than roughly 30% of the covering is failing, or repair quotes start approaching a third of replacement cost. A good roofer will show you photos from the roof to justify either answer.

Sometimes — an overlay saves tear-off cost but hides deck problems, adds weight, and often shortens the new roof's life and warranty. Many codes and manufacturers limit roofs to two layers. Tear-off costs more upfront and is usually the better long-term decision; get both options priced.

Access and safety costs (scaffolding, edge protection), roof pitch and height, tear-off vs overlay, material grade, and how honestly hidden deck repair is priced. A low bid that excludes safety equipment and deck contingency isn't cheaper — it's just billed later.

Get at least three quotes from established local firms in Paisley, ask each for recent local references and proof of insurance, and check membership of the national roofing trade body where one exists. Prioritise roofers who inspect from the roof (or with a drone) and show photos, over anyone quoting from the ground or the kerb.

A straightforward single-family roof takes 1-3 days for asphalt shingles or metal sheeting, and up to 1-2 weeks for tile, slate or complex multi-plane roofs. Weather delays are normal — a competent crew will never strip more roof than they can waterproof the same day.

A typical semi-detached re-roof runs £5,000-£12,000, with the national average around £8,000; large or complex roofs reach £13,000-£20,000+. Per-m² rates of £80-£150 including scaffolding are the usual quoting basis, and slate or clay costs substantially more than concrete tile.

Usually not for like-for-like replacement — but Building Regulations apply once you replace over 25% of the covering, and listed buildings or conservation areas may restrict material changes (e.g. swapping slate for concrete tile). Your roofer or local authority can confirm before work starts.
