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 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 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. Continuous exhaust at the peak. Together with the soffit intake, it moves heat and moisture out of the attic.
