The roofing system on this house
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. Every one of our replacements is a system, not just shingles. On this roof, from the deck up:
- 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.
