About the color: Granite Black
The homeowner picked Granite Black from the IKO Dynasty line. The swatch above is the manufacturer’s image of that blend. On a real roof it will read a little different depending on pitch, which way each slope faces and how much sun it gets. Granite Black has been one of the more popular picks lately: it went on 4 of the roofs in this recent-projects set. That’s why we bring full-size samples out and hold them up against the house in daylight.
The roofing system on this house
IKO Dynasty is a laminated architectural shingle built around a wide reinforced nailing strip IKO calls ArmourZone, which gives the installer a generous target and holds the fasteners where they belong. 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. It runs along the peak and lets hot, damp attic air escape. That protects the decking and keeps shingles from baking from below.
