What went on this roof
GAF Timberline HDZ is a laminated architectural shingle built with GAF LayerLock Technology, which bonds the shingle layers together, and a wide StrikeZone nailing area that gives the installer a large, clearly marked target. Every one of our replacements is a system, not just shingles. On this roof, from the deck up:
- Two layers of synthetic underlayment. That’s double our standard spec. The second layer adds another barrier under the shingles.
- 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.
- OC 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.
- GAF 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.
