The color on this roof
The work order lists the color as Harbor Blue. That name isn’t in our GAF Royal Sovereign color gallery, so we’re not showing a swatch that might be the wrong one. The image above is the shingle line itself. Your project manager can bring a full-size sample of any color out to your house. You can also browse every GAF Royal Sovereign color here.
The roofing system on this house
GAF Royal Sovereign is a traditional three-tab shingle, a flat, uniform look that suits smaller sections, outbuildings and homes originally built with three-tab. 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.
- GAF 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 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.
