Survey and Specification for York Properties
York has a diverse housing stock — from Victorian terraces with original Welsh slate to 1960s estates with concrete interlocking tiles now past their design life. Every replacement starts with a full survey including batten condition, sarking felt integrity, ventilation adequacy, and insulation assessment. We specify materials matched to the property era and North Yorkshire exposure conditions.
The Re-Roofing Process Step by Step
Strip the existing covering and inspect the timber structure. Replace any damaged rafters, battens, or fascia boards. Install breathable membrane, new battens at correct gauge, and tile or slate to manufacturer specification. Dress all flashings in new lead to Code 4. Install dry ridge and dry verge systems where appropriate. Final inspection, clean-up, and handover with guarantee documentation.
How Long a New York Roof Will Last
A properly specified and installed roof in York should last 60–80 years for natural slate, 50–60 years for clay tiles, and 40–50 years for concrete interlocking tiles. The North Yorkshire climate — with its vale humidity and 55+ annual frost days — means specification matters. We never cut corners on fixings, membrane, or ventilation because these are what determine real-world lifespan.

What a Full Re-Roof Involves
A roof replacement is a significant project and we treat it accordingly. The process begins with a comprehensive survey — not just the tiles, but the timber structure, membrane condition, insulation, ventilation, flashings, and rainwater goods. In York, we frequently find that properties due for re-roofing also need batten replacement (almost universal on pre-1980 roofs), ventilation improvements (inadequate ventilation causes condensation that rots new battens), and insulation upgrades (current Building Regulations differ significantly from what was standard when most York roofs were built).
During the re-roof itself, we work section by section — never stripping the entire roof at once. This means your property stays weathertight at the end of every working day. The typical sequence is: erect scaffold, strip one slope, inspect and replace timber as needed, install breathable membrane, fix new battens at correct gauge, tile or slate to manufacturer specification, dress all flashings, install dry ridge and verge where appropriate. Then repeat on the remaining slopes. Finally, install new rainwater goods if included, clean up the site, and hand over guarantee documentation.
For York properties in conservation areas — and there are many, covering the city centre, Clifton, Bishopthorpe, Heslington, and parts of Heworth — we source materials that comply with conservation requirements before starting. This may mean reclaimed Welsh slate, handmade clay tiles, or cast iron guttering. Lead time on specialist materials can be 2–4 weeks, so we build this into the project schedule from the outset.
