Roof Resealing and Seam Maintenance

Roof resealing removes failed sealant from seams, penetrations, and edges, prepares the surface, and applies new sealant appropriate to the roof material. It is preventive maintenance that costs far less than the water damage it avoids.

Symptoms

Signs you need this work

Cracked, shrunken or lifted sealant at seams
Staining on the interior ceiling
Sealant that has become chalky or brittle
Any roof accessory installed without visible sealing

Remove the old sealant first

Applying fresh sealant over failed sealant is the most common shortcut and it does not work. The new material bonds to the old, the old is already lifting, and the whole assembly comes away together.

We remove the failed material, clean and prepare the substrate, and apply new sealant matched to the roof material. It takes longer and it is the only version that lasts.
