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. 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.
- 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 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.
