Horton Roofing and masonry | Roofing Services in Seattle, WA 98104

Not always. Many Seattle roof leaks, especially those related to flashing corrosion, can be effectively repaired. We start with a thorough roof inspection to pinpoint the exact source—often a compromised seal around vents, chimneys, or in valleys. For localized damage, a targeted roof repair that addresses the flashing and surrounding shingles is usually sufficient and cost-effective. We only recommend a full roof replacement if the inspection reveals widespread wear, multiple leaks, or an aging roof system that can't be reliably sealed.

Sealing is crucial in our climate. Unsealed concrete and masonry are porous, absorbing rainwater which can lead to cracking from freeze-thaw cycles, erosion of mortar joints, and staining from moss and algae. Our professional masonry sealing creates a protective barrier that repels water, preventing moisture from penetrating and causing damage to your driveway, walkway, or retaining wall. This not only extends the life of your masonry but also reduces maintenance and keeps it looking newer, longer, despite our frequent rains.

Between professional inspections, keep an eye out for common signs of trouble: dark streaks or moss growth on shingles (indicating moisture retention), cracked, curled, or missing shingles, and granules collecting in gutters. Pay special attention to roof flashing—the metal around chimneys, vents, and skylights—for any signs of rust, lifting, or gaps. In your attic, look for water stains, mold, or daylight coming through the roof boards. If you notice any of these issues, especially after a storm, schedule a professional inspection with us to prevent a small problem from becoming a major leak.
