Roofing Services in Marengo, IA
Marengo Roofing & Maintenance handles every roofing job from a single-shingle repair to a full commercial re-roof. Here's what we do in Marengo.
Roof Replacement
Full roof replacement starts with a complete tear-off down to the deck. We inspect every board for rot or soft spots. In Marengo, we find decking damage on about 30% of tear-offs. Damaged sections get replaced with CDX plywood before anything else goes on. Then we build up: ice and water shield in valleys and at eaves, synthetic underlayment across the full deck, new drip edge on every edge, starter strip, field shingles, hip and ridge caps, and ridge vent. Dumpster, permits, and cleanup included.

Quick repairs prevent expensive problems. A $400 flashing fix today prevents $4,000 of interior water damage next year. If a repair makes sense, we recommend it. If your roof is too far gone, we'll be straight about that too. Either way, you get an honest answer and a written quote.

Storm damage is time-sensitive. Most insurance policies in Iowa require claims within 12 months. We do a free inspection, document every damaged area with photos and measurements, and help you file the claim. If the adjuster approves it, we handle the repairs at the insurance-approved price.

New construction means we get to do everything right from scratch. No compromises, no working around someone else's mistakes. Ice and water shield where it belongs, properly lapped underlayment, correct nailing patterns, and ventilation sized to the space. That's a roof that lasts.

Standing seam metal with Kynar 500 PVDF fluoropolymer finish. The gold standard for color retention and chalk resistance. We install Sheffield Metals and McElroy Metal panels in 24-gauge Galvalume steel. UL 2218 Class 4 impact resistance (qualifies for insurance discounts in most Iowa markets). UL 790 Class A fire rating. Wind uplift rated to 140+ mph per ASTM E1592 testing. Concealed Z-clips allow thermal expansion without stress on fasteners. That's what makes standing seam leak-proof.

GAF Timberline HDZ. The best-selling shingle in North America. With StrikeZone nailing area for consistent fastener placement. Class A fire rating per UL 790, Class 4 impact resistance per UL 2218 (when installed in the GAF Roof System), and Class H wind rating per ASTM D7158 (130 mph). We install Timberline in the full GAF system to qualify for Golden Pledge warranty: 25-year non-prorated workmanship plus 50-year materials with WindProven limited wind warranty (no max speed). That warranty is why we recommend GAF for most Marengo homes.

Flat roofs don't actually drain themselves. That's the challenge. Water ponds, UV breaks down the membrane, and eventually it leaks. We install and repair TPO, PVC, EPDM, modified bitumen, and built-up roofing systems designed for zero-slope conditions in Marengo.

TPO is our most-installed commercial membrane in Marengo. 60-mil thickness, hot-air welded seams, mechanically attached or fully adhered over polyiso insulation. The weld is stronger than the membrane. 15-20 year manufacturer warranties depending on system build-up.

We install gutter guards for homeowners who are done cleaning gutters twice a year. Micro-mesh over the opening, screwed into the front lip. Leaves and pine needles sit on top and blow off. Not 100% maintenance-free, but close. You might hose them once a year.

We don't charge extra for emergency tarp jobs. The tarping cost is rolled into the permanent repair price. If you need us at midnight during a storm, the price is the same as a Tuesday afternoon.

VELUX FS (fixed) and VS (vented) skylights installed with EDL flashing kits for shingle roofs. The multi-step flashing integrates with the surrounding shingle courses per IRC R903.2. We frame the curb with doubled 2x8 or 2x10 lumber (depending on rafter depth), install ice and water shield membrane around the entire curb perimeter, then set the skylight with factory sealant before weaving step flashing into the field. Top headwall flashing tucks under the upslope shingle course. Bottom sill pan diverts water onto the downslope shingles. Zero exposed sealant joints. Mechanical flashing only.
