Ernie Smith & Sons Roofing Case Studies: Multi-Layer Roof Removal and New OSB Decking for Victoria, Texas Home

Thursday, July 19th, 2018 by Ernie Smith


Many homes from the 1960s on the Texas Gulf Coast were topped with cedar shingles. When it was time for a new roof, a second layer of asphalt or composition was added, which was a fairly common re-roof procedure at the time. Such was the case with this one-story rambling ranch home in Victoria, Texas.

The house was a victim of Hurricane Harvey, which directly impacted the city of Victoria in August of 2017. Victoria is a county seat, and is located at the intersection of three major U.S. highways, about 30 miles inland from the Gulf of Mexico.  

The home was one of the hundreds of other insured claims we helped process in the aftermath of the storm, here in Victoria County and beyond.

Compliance with Texas Department of Insurance Windstorm code is not mandatory at this time in Victoria County, Texas, however at Ernie Smith & Sons Roofing all roofing products are installed to meet possible future enforcement of TWIA regulations. A city of Victoria permit for major structural repair was obtained prior to job start.


The one-time popular method of roofing over existing cedar shingles (and effectively allowing them to function as a ‘less than ideal’ nailing surface), essentially postponed the need for a pricey new solid wood deck, for a substantial number of years. Ultimately when the piper is paid, a major renovation is in order, with landfill fees alone running in the many hundreds of dollars.

Though less common these days, over the past thirty years Ernie Smith & Sons Roofing has completed hundreds of these labor-intensive and ‘debris-centric’ re-deck jobs just like this home in Victoria, Texas.

After grounds are secured, pitchforks and shovels remove two layers of roofing, exposing 1x4 lathes (atop rafters) that accommodated the home’s original wood shingles. Maximum speed and skill are a must as the home becomes instantaneously vulnerable to the elements.

Lathes are left in place and cleaned and prepared to receive approximately 185 sheets of 7/16” OSB decking (selected over plywood for cost savings). Decking is secured with steel panel sheathing clips and # 8 galvanized nails that penetrate rafters below.

Finally, we installed new pre-painted almond steel drip edge, GAF StormGuard® leak barrier valley underlayment, GAF felt buster roofing underlayment and a Timberline HD Charcoal color shingle with matching GAF Royal Sovereignty ridge and GAF Pro Start starter shingles.
