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. The shingle is only the top layer. Here’s the full system that went on this house:
- 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 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. Continuous exhaust at the peak. Together with the soffit intake, it moves heat and moisture out of the attic.
