Roof Replacement Service in Sammamish, WA, Seattle, and King County

If your roof is aging, leaking, or showing signs of damage, it may be time to consider a full roof replacement. At Sammamish Roofing, we specialize in high-quality roof replacement services for homeowners and businesses across King County and the broader Seattle region. Given the Pacific Northwest’s frequent rain, wind, and occasional snow, having a durable, reliable, and weather-resistant roof is essential to protecting your property and those inside of it.


Signs You May Need a Roof Replacement

  • Age: Depending on your roofing material, you may need an upgrade. For example, asphalt shingle roofs typically last 20-25 years, so if yours is older you may need a replacement.
  • Sagging Roof: A drooping roofline indicates that your roof may have structural issues in need of immediate attention.
  • Missing or Damaged Shingles: If your roof has many cracked, curled, or missing shingles, functionality and protective ability may be compromised, and a roof replacement may be recommended rather than pursuing piecemeal repairs.
  • Moss & Algae Growth: Seattle’s damp climate can result in moss and algae, which contribute to roof deterioration.
  • Leaks & Water Damage: Stains on ceilings or walls indicate moisture intrusion, and if significant enough, may require a replacement.
