At a glance: John Beal Roofing replaced the roof on Blow Street in St. Louis, MO 63116, finishing September 25, 2026. 13.00 squares of IKO IKO Dynasty, installed over synthetic underlayment across the full deck. Handled by our St. Louis office (314-429-6000).
This one was a 13.00-square roof (1,300 square feet), about what a standard ranch house carries on Blow Street in St. Louis, MO, south city around Bevo Mill and Holly Hills. It was one of 27 roof replacements our crews completed in St. Louis in September 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.

What went on this roof
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. People shop for the shingle, but what’s underneath it and how the edges are finished decide how long the roof lasts. On this job:
- A full layer of synthetic underlayment. It’s the backup water barrier under the shingles, and it holds up to foot traffic and wind far better than paper felt.
- 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 cap. Pre-formed cap that seals the hips and ridge.
- Lomanco Omni Roll ridge vent. Continuous exhaust at the peak. Together with the soffit intake, it moves heat and moisture out of the attic.
