The color on this roof
The work order lists the color as Appalachian Sky. That name isn’t in our IKO Dynasty color gallery, so we’re not showing a swatch that might be the wrong one. The image above is the shingle line itself. Your project manager can bring a full-size sample of any color out to your house. You can also browse every IKO Dynasty color here.
What went on this roof
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:
- 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.
- Self-sealing ice and water membrane where water concentrates. It seals around every nail driven through it, which matters in valleys and at the eaves.
- 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 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.
