Skagit-Ready Roofing Solutions

 Alpine Siding Pros installs premium asphalt shingles and standing-seam metal roofs designed for Skagit County’s heavy rains, snow loads, and valley winds. Our certified crews conduct thorough deck inspections, apply industrial-grade underlayment, and seal all flashings with corrosion-resistant sealants to prevent leaks, ice dams, and moisture intrusion.

Each roofing project begins with a structural assessment to uncover hidden rot or framing damage—courtesy rot repair is available at a nominal fee. Backed by manufacturer warranties and our on-time completion guarantee, your new roof will protect your home and elevate curb appeal for years.
