Person Allstar Roofing | Roofing Services in Alton, IL 62002

In Alton's climate, roof underlayment damage is often caused by persistent moisture, wind-driven rain, or improper initial installation. This hidden layer is your roof's last line of defense. We fix it by performing a detailed inspection to locate compromised areas, then carefully remove the affected shingles to replace the underlayment with high-quality, water-resistant materials. This repair restores your roof's waterproofing integrity and prevents leaks into your attic and home.

Preventing ice dams starts with ensuring proper attic insulation and ventilation to keep your roof's surface temperature even. If you already have ice dams, we first safely remove the ice to relieve pressure. We then inspect for and repair any resulting damage, such as damaged shingles, compromised flashing, or water-stained decking. Our repair process focuses on sealing entry points and often includes upgrading attic ventilation to prevent future dam formation during Alton winters.

Our local process is thorough and homeowner-focused. After a storm, we conduct a safe, exterior and interior inspection. We look for missing or damaged shingles, check gutters for granule loss (a sign of shingle wear), and inspect your attic for any signs of moisture or leaks, which are critical for spotting underlayment or ice dam issues early. We provide a clear, written assessment and explain all recommended repairs in plain terms, helping you make an informed decision to protect your Alton home.
