Our crew finished a 25.00-square roof, the size of a larger ranch or a modest two-story on Greenbriar Drive in Florissant, MO on Thursday, July 23. Florissant is one of the largest cities in North County, with neighborhood after neighborhood of 1950s and 1960s ranch homes. It was one of 8 roof replacements our crews completed in Florissant in July 2026. The system: synthetic underlayment across the full deck, 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:
- Synthetic underlayment over the whole deck. It’s stronger and more tear-resistant than felt, and it lies flat if weather rolls in during the tear-off.
- Ice and water membrane at the eaves and in the valleys. This self-adhering layer goes where water backs up: behind ice dams at the eaves and where two slopes meet.
- IKO Starter at the eaves and rakes. It’s a purpose-made starter strip with factory adhesive, not cut-up field shingles, so the edges stay sealed.
- 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. Continuous exhaust at the peak. Together with the soffit intake, it moves heat and moisture out of the attic.

What kind of ventilation went on this roof?
A Lomanco Omni Roll ridge vent along the peak. Paired with soffit intake, it lets hot, moist attic air escape.
