Improper step flashing is the leading cause of roof leaks at wall-to-roof transitions. Step flashing needs to be woven between shingle courses with each piece extending 4" above the shingle exposure. We see Bow homes where the last roofer used continuous L-flashing or just caulked the gap. That always fails. We tear it out and install proper step flashing with a kick-out diverter at the bottom per IRC R905.2.8.3.

Not all storm damage qualifies for a full replacement. Hail might only damage one slope. Wind might only lift shingles on the windward side. We document exactly what's damaged and let the insurance company make the call. Honest documentation gets claims approved. Inflated claims get denied.

We install new roofs on new homes, additions, detached garages, carports, and covered patios. Material options include asphalt architectural shingles, metal standing seam, metal corrugated, and flat membrane systems. We help you choose based on your budget, aesthetic preference, and the specific demands of your Bow climate.

We install 24-gauge and 26-gauge steel standing seam panels in Galvalume and pre-painted finishes. Concealed fastener clips allow the panels to expand and contract with temperature changes without stress on the fasteners. That's why standing seam doesn't leak. The clips float.

Asphalt shingles cover more homes in America than every other roofing material combined. There's a reason. They're affordable, they look good, they last 25-50 years depending on the grade, and they come in dozens of colors and profiles. Our Bow crews have installed thousands of shingle roofs and we know the product better than most roofers in the state.

The number one cause of flat roof failure is ponding water. Standing water that doesn't drain within 48 hours after rain. We solve ponding by installing tapered insulation systems that create positive slope to drains, scuppers, or roof edges. Minimum 1/4" per foot of slope eliminates standing water.

TPO is our most-installed commercial membrane in Bow. 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.

Gutter sizing matters more than most homeowners realize. We calculate the effective roof area, local rainfall intensity, and the number of downspout outlets needed to handle peak flow. Undersized gutters overflow. Undersized downspouts back up. We size everything to handle Bow's worst rain.
