On Carlsbad Drive in St. Louis, MO (south St. Louis County around Affton), the crew tore off and replaced a 14.67-square roof (1,467 square feet), about what a standard ranch house carries. It was one of 29 roof replacements our crews completed in St. Louis in May 2026. IKO Dynasty went over two layers of synthetic underlayment, a heavier spec than our standard single layer, with ice and water membrane at the eaves and valleys.

Materials installed, layer by layer
IKO Dynasty is a laminated architectural shingle built around a wide reinforced nailing strip IKO calls ArmourZone, which gives the installer a generous target and holds the fasteners where they belong. 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.
- Self-sealing ice and water membrane where water concentrates. It seals around every nail driven through it, which matters in valleys and at the eaves.
- 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.
