This roof is 40 squares (4,000 square feet).  We tore off the existing shingles and underlayment. We installed new drip edge, synthetic underlayment, starter shingles, 18” wide galvanized metal in valleys and new Owens Corning Duration series shingles.We mostly use Owens Corning Duration series shingles, which carry a 130 MPH wind rating. We replaced three slant back vents with new turbines and decked over an old cooler duct that was not in use anymore. We sealed all pipes and penetrations and painted them to match the color of the shingle.

We pulled a city permit for the roofing project and passed final inspection. This project took our crew two days to complete. We had 13 men on the first day working from 7:00 AM until 5:00 PM and 8 men on the second day working from 7:00 AM until 5:00 PM. Our Owens Corning shingle reroofs carry a 10 year labor warranty and 50 year material warranty.

The homeowner went from a green roof to the color “driftwood”. This particular Home Owners Association would not let the homeowner go with green again, so the homeowner was limited on what color they could choose.

Here is some basic information on RhinoRoof synthetic underlayment:

(You can also go to the Owens Corning website listed here:

  1. The underlayment has a great tear resistance up to 2X stronger than other types of underlayment.
  2. There is a back coating that holds to the deck and a fiber-grip on the front side to help keep installers from slipping.
  3. Can stand up to UV rays for up to 3 months if it is exposed.
