For most homeowners in King County, Snohomish County, and throughout the Pacific Northwest, roof replacement happens once every 20–30 years, meaning it’s often a first-time experience. But with high costs, contractor decisions, and long-term implications, it’s easy to overlook key details.
Whether you’re replacing an aging asphalt roof or upgrading to a more durable material, this guide will walk you through the most common mistakes and how to avoid them.
1. Not Getting a Full Roof Evaluation Before Planning
Before requesting quotes, make sure your contractor has actually inspected your attic, decking, and ventilation system. Your roof isn’t just what you can see from the outside and underlying issues like moisture damage, poor airflow, or inadequate insulation can impact the success of your new roof.
2. Focusing Only on Price, Not Value
It’s tempting to choose the lowest bid, but that often means cut corners; especially with underlayment, ventilation, flashing, and fasteners. In the PNW climate, those components matter just as much as the shingles themselves.
Ask:
- What kind of underlayment is included?
- Are valleys and penetrations getting ice/water barrier?
- Will attic ventilation be upgraded or evaluated?
3. Not Choosing the Right Material for Our Climate
In the Pacific Northwest, algae resistance & moisture protection should guide your material choice, not just style or price. Talk to your contractor about:
- Architectural shingles (better protection and wind resistance)
- Metal roofing (excellent as a lower maintenance option)
4. Waiting Too Long to Schedule
Roofing contractors book up quickly in dry months (especially from May through September). If your roof is aging, don’t wait for active leaks. The longer you delay, the higher the risk of:
- Internal water damage
- Insulation issues
- Full deck replacement instead of just shingles
6. Skipping the Cleanup Questions
Make sure to ask how the crew will clean up nails, debris, and haul-away materials. Will they use magnetic rollers? Will landscaping be protected? A professional roofing team should leave your property in better condition than they found it.
