The roofing system on this house
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. 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:
- 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.
- 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.
