Tuckpointing & Mortar Systems

Parapet walls and chimneys rely on sound mortar joints to keep water out of the roof system below. Over time, mortar joints weather, crack, or crumble, letting moisture work its way into the masonry and eventually into the roof deck. Tuckpointing removes the failing mortar and packs new mortar into the joints, restoring a tight seal along these vulnerable roof-adjacent structures.

Where Tuckpointing Fits on a Flat Roof

Parapet Walls — The mortar joints along parapet caps and faces are common entry points for water once they open up.
Chimneys — Chimney masonry sits directly in the path of roof drainage and needs solid mortar to shed water correctly.
Flashing & Scupper Systems — Mortar repair works alongside sealed flashing and scupper details to keep water moving off the roof edge rather than into the wall.

Signs Mortar Repair Is Due

Crumbling or Missing Mortar — Gaps between bricks or blocks signal it's time for tuckpointing before water finds its way in.
Interior Moisture Near Chimneys — Staining or dampness inside near a chimney often traces back to open mortar joints outside.
