How often should I inspect my roof?

It is a good idea to inspect the inside of your roof at least once annually to check that it’s still weatherproof and there is no woodworm infestation.  Repeat your check in different weather conditions. A check after heavy rain will reveal any water ingress as a result of any defects in the structure. A check in winter weather will reveal any condensation within the roof space.

When inspecting you roof from outside at ground level use binculars to look for slipped or dislodged tiles. If tiles or slates have slipped there may be a difference in colour to those around them. At the ridge line check for missing ridge tiles and gaps in mortar and at flashings around chimneys. One of the most obvious signs is pieces of mortar laying on the ground or on the other tiles on the roof.
