Slate Roofing in Falkirk & Central Scotland
Natural slate is the classic Scottish roof — beautiful and long-lasting, but only when it’s laid and maintained by people who know it. F J Allan & Sons install, renew and repair slate roofs across Falkirk, Stirling, the Forth Valley and North Lanarkshire, matching new work to the character of your home.
From a handful of slipped slates to a full roof renewal, we’ll tell you honestly what your roof needs.
Our slate roofing services
New slate roofs
Full natural or fibre-cement slate roofs, laid to last, with proper underlay, battens and ventilation.
Re-slating & roof renewal
When a slate roof reaches the end of its life we strip and re-slate it — often re-using sound slates where we can.
Slate repairs
Slipped, cracked and missing slates refixed or replaced, with matching slates sourced wherever possible.
Ridge, hips & leadwork
The details that keep a slate roof watertight — re-bedded ridges, hips and precision lead flashing.
Common slate roof problems
Slipped & broken slates
The classic cause of leaks — individual slates that have slipped or cracked, letting water past the underlay.
Nail sickness
When the old fixings rust through, slates start slipping all over the roof — usually a sign it’s time to re-slate.
Failed flashings & valleys
Lead around chimneys and in valleys is a common leak point on older slate roofs.
Sagging & damaged battens
Rotten battens or sarking under the slates need addressing during a renewal for a lasting result.
Why choose F J Allan?
Slate is a craft, and we treat it like one — the right slate, the right fixings, proper leadwork and ventilation. As qualified, insured roofers with 25+ years’ experience we’ll match new work to your existing roof and never sell you a full re-slate when a repair will do. 10-year workmanship guarantee, tidy work, honest advice.
What affects the cost of a slate roof?
Every slate roof is different. The main cost factors are:
- Repair vs full re-slate — a few slipped slates is a quick job; a full renewal is a bigger investment.
- Slate type — natural Scottish/Spanish slate vs fibre-cement.
- Roof size, pitch and access.
- Condition of the timber underneath — battens and sarking.
We give a clear, fixed price after a proper look at the roof.

What our customers say
Slate roofing FAQs
How long does a slate roof last?
A well-laid natural slate roof can last 80–100 years or more; fibre-cement slates typically 30–50. The fixings and flashings usually need attention before the slate itself.
Can you match my existing slates?
Usually, yes — we source matching or close-match slates and re-use sound originals where we can, so repairs blend in.
Natural or fibre-cement slate — which should I choose?
Natural slate looks best and lasts longest; fibre-cement is lighter and lower cost. We’ll advise based on your home and budget.
Should I repair or re-slate my roof?
If the slates are sound and it’s just fixings or flashings, a repair is fine. Widespread nail sickness usually means a re-slate is the better long-term value.
