Rochdale roof guide
Rochdale Roof Fault Finder
Start with what has actually happened and use that to decide which part of the roof should be checked first.

Water on an upstairs ceiling
Look at what sits above and uphill from the stain: open roof slope, chimney, valley or roof window.
A slate or tile has moved
Photograph it from safe ground and compare it with the courses around it.
Water is running down an outside wall
Watch the gutter during rain and see whether water is getting behind the fascia.
The wall is damp beside a chimney
The lead, pointing, masonry and rear chimney detail all need checking.
A previous repair did not solve the leak
Note the weather conditions when it came back and find out exactly what part of the roof was repaired.
Want somebody to inspect the roof?
Tell the roofer what has happened, where you have seen the problem and what the weather was like at the time.
