Materials installed, layer by layer
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. 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 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.
- Ice and water shield in the valleys and along the eaves. Those are the two places a Midwest roof takes on water first, from ice dams in January and heavy runoff in spring storms.
- 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. Continuous exhaust at the peak. Together with the soffit intake, it moves heat and moisture out of the attic.
