Heat-dried flashing and sealant around vents and chimneys
Why it happens here
Fullerton summers regularly hit 95 degrees or higher. That heat bakes the sealant around vents, chimneys, and skylights until it cracks. Once it cracks, water gets in during the first rain. This is the most common leak we see in 92831 and 92835.
Our approach
We remove the old sealant, clean the surface, and apply a high-temperature sealant rated for Fullerton's heat. We also check the flashing itself and replace any pieces that are rusted or bent. This fix usually lasts five to seven years.
