When to book a roof moisture scan
Most clients come to us at one of four points, when the cost of guessing what is wrong with the roof starts to outweigh the cost of finding out.
- A leak keeps coming back after repair. The scan shows how far the water has travelled, so the next repair deals with all of the wet area rather than just the visible one.
- Your roof is due for refurbishment. Knowing which areas are wet tells you whether parts of the existing roof can stay in place or need to be stripped.
- You are setting maintenance budgets. Evidence of the roof’s condition lets you plan spending instead of reacting to the next leak.
- You are buying, selling or leasing a building. A scan gives you the roof’s real condition before you agree on a price or sign a lease.
From scan to targeted repair
Because we are both a roof surveying company and a roofing contractor, the quote that follows your survey is a full project costing, including the access and health and safety requirements of the job. When only part of your roof is wet, the work can be limited to those areas through flat roofing repairs rather than a full replacement.
Materials are installed by manufacturer-approved operatives, and new roofing can carry a single point guarantee of between 10 and 25 years, depending on the project.
Accredited roof surveyors and contractors
We are members of the National Federation of Roofing Contractors (NFRC) and accredited under CHAS and Constructionline. You can see the full list on our awards and accreditations page.
Other roof surveys and diagnostics
A moisture scan tells you where your roof is wet, but it is not always the best tool for finding where water gets in. Electronic leak detection locates leaks in most types of waterproofing membrane, while a commercial roof survey assesses the overall condition of your roof. You can see every method we offer on our roof surveys and diagnostics page.
