Materials installed, layer by layer
Dynasty is IKO's performance architectural shingle. Its signature is ArmourZone, a reinforced fabric strip across the nailing area that gives every nail a wide, tough landing spot. The shingle is only the top layer. Here’s the full system that went on this house:
- Synthetic underlayment, edge to edge. It doesn’t wrinkle or tear like felt, and it keeps the deck dry if a shower pops up mid-job.
- 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. It runs along the peak and lets hot, damp attic air escape. That protects the decking and keeps shingles from baking from below.
