The result is a roof that looks pristine and performs even better, giving Kelso homeowners lasting peace of mind no matter what the forecast holds.
FAQs
What is upgraded underlayment and why is it important after storm damage?
Upgraded underlayment—often a synthetic moisture-barrier sheet installed between the roof deck and the shingles—offers superior tear resistance, water repellency, and UV stability compared with traditional 15- or 30-lb asphalt felt. After a wind or hailstorm, your primary shingles may have been bruised, lifted, or blown off, leaving the deck vulnerable. Installing a tougher, self-healing synthetic layer during restoration gives your Kelso home an added line of defense against future wind-driven rain, ice dams, and debris, reducing the likelihood of leaks and extending the overall service life of the new roof system.
How does upgraded underlayment improve protection compared to standard felt paper?
High-performance synthetic underlayments are manufactured from woven or spun-bonded polymers that weigh less yet have 20–30 times the tensile strength of felt. They won’t wrinkle, absorb water, or become brittle in cold weather. Most synthetics also feature proprietary slip-resistant coatings, allowing our technicians to fasten the material tighter and flatter to the deck. The result is an underlayer that sheds water faster, resists tearing around fasteners, and stays intact even if shingles blow off in the next big Pacific Northwest storm.
Will my homeowners insurance cover the cost of upgrading underlayment during storm damage restoration in Kelso?
Insurance policies typically pay to return your roof to its pre-loss condition, so they automatically cover replacement of any underlayment that was damaged in the storm. Many policies also allow for "like kind and quality" upgrades when code changes or manufacturer installation requirements specify a higher-grade underlayment. Our team documents all storm-related damage, provides your adjuster with code citations (such as IRC R905.2 for asphalt roofs), and submits the supplemented estimate. In most cases, the incremental cost of upgrading from felt to synthetic is either fully or largely reimbursed—leaving you responsible only for your deductible.
How long does it take to remove damaged shingles, install upgraded underlayment, and reroof my home?
For an average 2,000-sq-ft single-family residence in Kelso, full tear-off and installation typically spans 1–2 working days, weather permitting. Day 1 involves removing debris, inspecting the deck for hidden rot, replacing any compromised sheathing, and rolling out the synthetic underlayment with required ice- and water-shield in valleys and eaves. Day 2 is reserved for shingle installation, flashing, ridge-vent work, and a thorough cleanup. Larger or more complex roofs may take an extra day. Because synthetics have excellent UV resistance, your home stays watertight overnight even if shingle installation is delayed.
Can upgraded underlayment help lower my energy bills or improve attic ventilation?
While underlayment’s primary role is moisture protection, premium synthetic products are thinner and lay flatter, allowing shingles to sit uniformly and work better with ridge and soffit vents. Some brands incorporate reflective or breathable layers that can reduce attic temperatures by 5–10°F in summer, easing the load on your HVAC system. Coupled with proper insulation and balanced airflow, the right underlayment can contribute to modest energy savings and help mitigate condensation issues common in the damp Kelso climate.
What should I look for in a storm-damage restoration contractor for upgraded underlayment in Kelso?
Choose a local, licensed roofer (WA Contractor #) who: 1) is certified by major shingle and underlayment manufacturers; 2) offers written, transferable warranties on both materials and workmanship; 3) understands insurance protocols and can assist with claim documentation; 4) provides references from recent Kelso or Cowlitz County storm restorations; and 5) maintains proper safety and environmental practices, including on-site recycling of old shingles. A reputable contractor should also walk you through underlayment options, explain code requirements, and provide a detailed scope of work so you can make an informed decision.
