At a glance: John Beal Roofing replaced the roof on Duke Drive in St. Louis, MO 63136, finishing May 28, 2026. 20.00 squares of IKO IKO Dynasty, color Glacier, installed over synthetic underlayment across the full deck. Handled by our St. Louis office (314-429-6000).
This one was a 20.00-square roof (2,000 square feet), about what a standard ranch house carries on Duke Drive in St. Louis, MO, north St. Louis County around Jennings. It was one of 29 roof replacements our crews completed in St. Louis in May 2026. The system: synthetic underlayment across the full deck, ice and water membrane in the valleys and at the eaves, and IKO Dynasty in Glacier on top.

Why this house went with Glacier
The homeowner picked Glacier from the IKO Dynasty line. The swatch above is the manufacturer’s image of that blend. On a real roof it will read a little different depending on pitch, which way each slope faces and how much sun it gets. Glacier has been one of the more popular picks lately: it went on 5 of the roofs in this recent-projects set. If you like it, ask us to bring a full-size piece out and hold it up against your own house.
What went on this roof
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. 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.
- 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.
