About the color: Frostone Grey
This house got Frostone Grey. A small swatch never tells the whole story, because a full roof reads lighter or darker depending on how the slopes face and the light hits them. Frostone Grey has been one of the more popular picks lately: it went on 47 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
Dynasty is IKO's performance architectural shingle. Its signature is ArmourZone, a reinforced fabric strip across the nailing area that gives every nail a wide, tough landing spot. 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.
