What went on this roof
Timberline HDZ is GAF's architectural shingle with a wide StrikeZone nailing area and LayerLock Technology holding the two layers of the shingle together, 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:
- 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 shield in the valleys and along the eaves. Those are the two places a Midwest roof takes on water first, from ice dams in January and heavy runoff in spring storms.
- Factory 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. It runs along the peak and lets hot, damp attic air escape. That protects the decking and keeps shingles from baking from below.
