Duncombe Area Roofing Contractor. GAF Certified

GAF Timberline HDZ shingles with StrikeZone nailing area for Class 4 impact resistance rated to UL 2218. We install the full GAF Roof System. Cobra ridge vent, FeltBuster synthetic underlayment, Starter Match starter strip, and Seal-A-Ridge caps. That qualifies your Duncombe home for the Golden Pledge warranty: 25-year workmanship plus 50-year material.

Missing shingles cause water intrusion through the exposed underlayment and decking. We don't just replace the missing shingle. We check the deck for moisture damage with a Protimeter pin meter, replace any compromised underlayment, and weave new CertainTeed Landmark shingles into the existing pattern.

Storm damage claims in Iowa have a 1-year filing window with most carriers. Don't wait. We'll inspect your roof, document the damage, and help you file before the deadline. If there's no damage, we'll tell you that too.

New roof installation on new construction means getting the ventilation right from the start. We calculate intake and exhaust requirements based on attic square footage and install the right combination of soffit vents and ridge vent. Saves you money on cooling bills in Iowa.

We do metal roof repairs too. Loose panels, failed sealant at transitions, rust spots on older galvanized. Not every metal issue needs a full replacement. Our Duncombe crew can usually fix it same-day.

Three-tab shingles are cheaper upfront but they don't hold up like architectural. We recommend them for sheds, detached garages, and rental properties where budget matters more than aesthetics. For your Duncombe home? Go architectural.

Flat roofs need special attention. Water doesn't run off, it sits. We install TPO, PVC, EPDM, and modified bitumen systems designed to handle ponding water in Iowa's climate.

Roof coatings can extend the life of your commercial roof by 10-15 years for a fraction of replacement cost. We apply silicone and acrylic coatings over existing TPO, EPDM, and metal substrates. Not every roof qualifies. We'll be straight with you.

Clogged gutters cause fascia rot. We see it on every other house in Duncombe. We install new gutters with proper pitch, adequate downspout capacity, and optional gutter guards if you're done cleaning them twice a year.

Annual roof inspections catch small problems before they become expensive ones. A cracked pipe boot is a $150 fix. Ignoring it means $3,000 in ceiling and wall water damage. We recommend an inspection every 2-3 years for roofs under 10 years old, and annually after that.

After we tarp and secure your roof, we document everything for insurance purposes. Photos, measurements, damage descriptions. Your adjuster gets a professional report, not a handwritten note.

A skylight installed wrong will leak. The flashing has to integrate with the shingle courses. Step flashing on the sides, headwall flashing on top, and a sill pan underneath. We use manufacturer flashing kits because they're engineered to work with the skylight frame.
