Do I need listed building consent for roof repairs?
Not for genuine like-for-like repairs: replacing broken slates with matching slates, re-bedding a ridge in the same mortar or renewing a lead flashing to the same detail does not alter the building. You do need consent to change materials, alter the roof shape or add roof windows or solar panels, and doing that work without consent is a criminal offence. When in doubt we ask the conservation officer first — it costs nothing.
Can you match old slates and tiles?
Yes — it is most of the skill. Welsh and Westmorland slate, clay pantiles and plain tiles all vary by age and maker, so we match by size, colour, texture and weathering rather than by name, and use reclaimed material where the original is no longer made. We sourced exact matches for the Walkington property before starting.
Why lime mortar rather than cement?
Most listed roofs were built with lime mortar, which stays slightly flexible and lets moisture escape. Hard cement mortar cracks against old tiles, traps water and is usually refused by conservation officers. We use lime where the roof was built with it.
Will you deal with the conservation officer?
We prepare the specification and photographs the officer needs and are happy to speak to them directly. The formal application is made by you as the owner, or by your agent, and we tell you exactly what to put in it.
Is a drone survey suitable for a listed building?
Yes, and it is often the best way to see one: every slope, chimney and gutter of a large or fragile roof from the air, with no scaffold and nobody walking on old slates. We are a CAA-registered operator and deliver the footage, photos and a written report.
How much more does listed roofing cost?
The materials cost more — reclaimed slate, handmade clay tiles, lead and cast iron are all dearer than modern equivalents — and the work is slower. What does not change is how we price it: a free assessment, then one fixed written figure, and no deposit.
