FAQs
What is driving rain and why is it a problem for roofs in Palmer?
Driving rain—sometimes called wind-driven rain—occurs when high winds push heavy rainfall horizontally against exterior surfaces. In Palmer, strong Mat-Su Valley winds frequently accompany storms, forcing water under shingles, flashing, and siding. Because our temperatures swing from freeze to thaw, any moisture that gets into the roof deck can expand, contract, and rapidly deteriorate materials, leading to leaks, mold, and premature roof failure.
What roofing materials perform best against driving rain in Palmer’s climate?
We recommend high-quality architectural asphalt shingles with enhanced sealant strips, standing-seam metal panels with concealed fasteners, or synthetic composite shingles rated ASTM D3161 Class F for high wind. All three options shed water efficiently, resist uplift to at least 110 mph, and carry manufacturer warranties that remain valid in Palmer’s cold, windy conditions. Ice-and-water shield underlayment installed from the eaves to at least 24" past the warm wall further blocks wind-driven moisture.
How can I tell if driving rain has damaged my roof?
Inside the home, look for brown ceiling stains, peeling paint, or musty odors after a storm. In the attic, inspect the underside of the sheathing for dark spots or damp insulation. Outside, check for raised shingles, missing ridge caps, or granules collecting in downspouts. Because wind-driven rain can force water higher than the leak point, the source is not always obvious; scheduling a professional moisture-intrusion inspection after major storms is the surest way to catch hidden damage.
What specific installation techniques do you use to protect roofs from wind-driven rain?
Our crews follow a six-step protocol: 1) Full-coverage ice-and-water membrane along eaves, valleys, and all penetrations; 2) Synthetic breathable underlayment mechanically fastened on 4" overlaps; 3) Hurricane-rated starter strips and shingle courses hand-sealed at edges; 4) Corrosion-resistant ring-shank nails driven per manufacturer’s high-wind nailing pattern; 5) Closed-cut or woven valleys reinforced with ice shield and metal valley flashing; 6) Extra-wide drip edge and step flashing set in polyurethane sealant. These steps create a continuous secondary barrier when rain is blown beneath the surface layer.
Are there local building codes in Palmer that address wind-driven rain protection?
Yes. The City of Palmer follows the 2018 International Residential Code with local amendments. Section R903.4.2 requires ice-barrier underlayment from the eave edge to a point 24" inside the warm wall. Fastener schedules must meet 110 mph ultimate design wind speed (ASCE 7-16). Flashing must comply with IRC R903.2 to divert water away from walls. We pull all necessary permits, meet or exceed code, and arrange city inspections so your new roof is fully compliant and insurable.
How much does it cost to upgrade my roof for better protection against driving rain, and is financing available?
Pricing depends on material, pitch, and square footage, but most Palmer homeowners spend $6–$10 per square foot for an architectural-shingle system with ice shield, or $10–$15 per square foot for standing-seam metal. These quotes include tear-off, disposal, permits, and a 10-year workmanship warranty. We offer 12-month same-as-cash financing and long-term low-interest payment plans through our lending partner.
