Leak Risk Profile
Rosanna Roofing & Weather Profile
What We See in Rosanna
After heavy rain, the typical pattern of water ingress is not a single dramatic leak but a series of small drips tracking along ceiling joists or insulation batts before appearing at a visible point. The stain on the ceiling is rarely directly below the entry point.
Why It Happens
Roof penetration flashings fail at their perimeter seals — typically a silicone or butyl bead that hardens under UV exposure and loses its adhesion to the tile surface. Once the seal fails, water tracks under the collar fitting and enters the roof space at the penetration point.
How We Fix It
Chimney flashing repairs are done in two stages: physical re-set of the step flashings into properly cut raggle grooves bedded in non-setting mastic, followed by a lead dress to the flashing face. Sealant-only repairs on chimney flashings are temporary measures.
