Why this house went with Shadow Brown
The homeowner picked Shadow Brown 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. Shadow Brown has been one of the more popular picks lately: it went on 19 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.
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. Every one of our replacements is a system, not just shingles. On this roof, from the deck up:
- 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.
- 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 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.
