Why this house went with Summit Grey
The homeowner picked Summit Grey 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. Summit Grey has been one of the more popular picks lately: it went on 21 of the roofs in this recent-projects set. Our project managers bring real samples to the house so you can see them next to your brick, siding and trim.
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 membrane at the eaves and in the valleys. This self-adhering layer goes where water backs up: behind ice dams at the eaves and where two slopes meet.
- 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. It runs along the peak and lets hot, damp attic air escape. That protects the decking and keeps shingles from baking from below.
