A leak-free roof does more than protect your home!

A leak-free roof does more than protect your home—it safeguards your family’s health in the rainy Pacific Northwest.

In the Greater Portland Area, where average annual rainfall hovers around 36 inches, even minor leaks pose serious risks. Our damp climate accelerates problems: water infiltrates through cracked shingles, damaged flashing, or poor seals, leading to wood rot in attics, walls, or ceilings within a short time. This creates ideal conditions for mold growth, a common issue in humid regions.

Health authorities like the CDC and NIEHS link indoor mold exposure—especially species like Aspergillus—to respiratory problems, including worsened asthma, allergies, coughing, wheezing, and irritation of the eyes, nose, and throat. Vulnerable groups, such as children, the elderly, and those with pre-existing conditions, face higher risks. Damp environments also degrade indoor air quality, trapping spores and musty odors that circulate in tightly sealed winter homes.

Structural damage compounds the issue: rotted beams weaken your home, while wet insulation holds moisture, fueling a vicious cycle.

Prevention is straightforward and essential here:

• Inspect and repair leaks promptly, especially after storms—focus on flashing, vents, and shingles.
• Ensure proper attic ventilation to reduce trapped humidity.
• Maintain indoor relative humidity between 30-50% (EPA recommendation) with dehumidifiers during soggy seasons.
• Watch for warning signs: water stains, bubbling paint, musty smells, or visible mold—address them immediately.

In our consistently wet climate, a well-maintained, leak-free roof isn’t a luxury—it’s a frontline defense for better air quality, structural integrity, and overall wellness. Act now to keep small issues from becoming big health hazards. Your family deserves to breathe easy year-round.
