About the color: 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.
The roofing system on this house
With IKO Dynasty, the detail that matters most is the ArmourZone nailing strip: a wider, reinforced band where the nails go, so fasteners land where they hold best. 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, 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 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 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.
