Your Questions
Need to discuss something specific to your roof?
Speak To Our TeamThat depends on the condition around the defect, not just the size of the leak. A local repair can be sensible when the surrounding covering, fixings and structure remain sound. If several parts are failing or moisture is trapped within the build-up, a more extensive renewal may be appropriate. We assess the roof before recommending the scope.
We cover London, Surrey and Berkshire, with contact addresses in South Kensington and Cobham. Our areas directory lists the places we serve. Give us your property postcode when you enquire so we can discuss access and arrange the appropriate next step.
Yes. Photographs of the roof and the inside symptom can be useful, provided they are taken safely from the ground, a window or an accessible loft. Send the postcode, explain when the problem started and mention any recent work. Do not climb onto a wet or damaged roof to obtain photographs.
