Frequently asked questions
How long does a full roof replacement take?
Most domestic re-roofs take between one and two weeks depending on roof size, complexity and weather — we confirm a realistic timescale as part of your quote.
Will I need to move out during the work?
No, you can normally stay in the property throughout. We take care to minimise disruption and keep the house weathertight at the end of each working day.
Can you also upgrade insulation while replacing the roof?
Yes — a re-roof is the ideal time to upgrade insulation. See our roof insulation upgrades service, which we're happy to combine with a replacement project.
Do you handle scaffolding and permissions?
Yes, we arrange scaffolding as part of the project and advise on any planning considerations, particularly for listed or conservation-area properties.
What roofing materials do you install?
We work with concrete and clay tiles, natural and reconstituted slate, and can advise on the best option for your property style and budget.
