Roof Replacement Questions, Answered
How long does a roof replacement usually take?
Most domestic roof replacements take between 3 and 7 days, depending on the size and pitch of the roof, the material chosen and the weather. We'll always give you a realistic timeframe as part of your free quotation.
Do you offer free quotes?
Yes - we offer free, no-obligation site visits and quotations on all roof replacement work, from small repairs through to full re-roofs.
How do I know if I need a full roof replacement or just repairs?
If tiles are slipping or cracking across large areas, or the roof has reached the end of its expected lifespan, replacement is usually the better long-term option. Smaller, isolated issues like a handful of damaged tiles or a leaking flashing can often be repaired. We'll always give you an honest recommendation rather than pushing for a full replacement unnecessarily.
Do you carry out both domestic and commercial roofing work?
Yes, we replace roofs on homes, extensions, garages and outbuildings as well as commercial and industrial buildings across Dorset.
What's the difference between concrete, clay and natural slate tiles?
Concrete tiles are the most cost-effective and widely used, clay tiles offer a traditional look with excellent breathability, and natural slate is the premium option with the longest lifespan. We'll talk you through the right choice for your budget, property style and any conservation area requirements.
