About the color: Glacier
The homeowner picked Glacier 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. Glacier has been one of the more popular picks lately: it went on 5 of the roofs in this recent-projects set. If you like it, ask us to bring a full-size piece out and hold it up against your own house.
Materials installed, layer by layer
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:
- 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.
- 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 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.
