Roof Repointing

Roof repointing is the process of renewing the pointing (external part of the mortar joints) in a roof. Over time, weathering and decay causes voids in the joints between roof tiles, allowing the undesirable ingress of water. Water entering through these voids can cause significant damage through freeze/thaw cycles and from salt dissolution and deposition.

Professional roof repointing can dramatically increase the lifetime of your roof by 15 – 25 years.

The repointing process begins by removing damaged pointing to a depth equal to or slightly more than the width of the joint, or to the point where sound mortar is reached. Depths greater than 2 1/2 inches or 4cm are filled in several passes, allowing the mortar to cure for at least 24 hours.
