What Alton Customers Say
"The Golden Pledge warranty was a big factor in our decision. 25 years on workmanship plus 50 on materials. Knierim Roofing & Maintenance is one of the few local companies that can even offer it."
"We got three quotes for a full tear-off and Knierim Roofing & Maintenance was the most thorough. They showed us the rotted decking in the photos before replacing it. New Timberline HDZ shingles look great."

We've been installing and repairing roofs for over 24 years. That experience shows in how we handle complex roof lines, unexpected deck damage, and insurance claim disputes. We've seen everything and know how to handle it.
Storm Damage Specialists
Hail, wind, and monsoon damage are common in IA. Our team includes HAAG Certified inspectors who document damage the way adjusters expect it. We handle the entire insurance claim process so you don't have to.
