Why this house went with 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.
What went on this roof
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. The shingle is only the top layer. Here’s the full system that went on this house:
- Synthetic underlayment, edge to edge. It doesn’t wrinkle or tear like felt, and it keeps the deck dry if a shower pops up mid-job.
- 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 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.
