Common signs include higher-than-usual energy bills, damp spots on ceilings or walls, a musty smell in the attic, and visible mold growth. The persistent moisture in our air can seep into compromised areas. We recommend a professional inspection, especially before the rainy season, to assess insulation integrity and prevent more extensive damage.

In San Francisco, recurring leaks often point to a systemic issue rather than an isolated spot. The problem could be compromised flashing around chimneys or vents, deteriorated underlayment, or poor drainage on low-slope roofs. A temporary patch rarely addresses the root cause driven by our wind-driven rain. Our comprehensive leak detection identifies the exact failure point for a permanent repair.

The most critical pre-winter steps are cleaning gutters and downspouts to prevent overflow, inspecting and sealing flashings (the metal strips around protrusions), and checking for cracked or missing tiles or shingles. Given our wet season, ensuring proper drainage and sealing potential water entry points is essential to avoid the common issues of insulation moisture and leaks.
