On Park Avenue in Saint Charles, MO (the St. Charles County seat on the Missouri River, where subdivisions run from 1970s split-levels to newer two-story builds), the crew tore off and replaced a 31.67-square roof, the size of a larger ranch or a modest two-story. It was one of 3 roof replacements our crews completed in Saint Charles in June 2026. The system: two layers of synthetic underlayment, a heavier spec than our standard single layer, ice and water membrane in the valleys and at the eaves, and IKO Dynasty on top.

Materials installed, layer by layer
With IKO Dynasty, the detail that matters most is the ArmourZone nailing strip: a wider, reinforced band where the nails go, so fasteners land where they hold best. Every one of our replacements is a system, not just shingles. On this roof, from the deck up:
- Two layers of synthetic underlayment. That’s double our standard spec. The second layer adds another barrier under the shingles.
- Ice and water shield in the valleys and along the eaves. Those are the two places a Midwest roof takes on water first, from ice dams in January and heavy runoff in spring storms.
- IKO Starter strip along every edge. The first course is where wind gets under a roof. A factory starter with its own sealant line locks it down.
- IKO Hip & Ridge on the hips and peak. Matching cap shingles made for the job, not field shingles cut into pieces.
- Lomanco Omni Roll ridge vent. It runs along the peak and lets hot, damp attic air escape. That protects the decking and keeps shingles from baking from below.
