  1. Gents, Thank you for your feedback, in case you were wondering. The shingle manufacturer concluded, the Roofer failed to replace 20 feet of ridge vent above the cathedral ceiling and instead used shingles preventing moisture from venting and causing mold to form on the beam. The Roofer has since re-installed the ridge vent and made internal repairs. Best Regards, Geek Specialist
  2. Thank you everyone for your thoughtful comments and ideas, I want to share the current working hypothesis. A Houston roofing and construction firm came out to inspect the house. Not shown in the photograph is the continuation of the cathedral ceiling to an outdoor patio. Twenty feet to cathedral ceiling is indoors and extends an additional 10 feet outdoors. The entire length of the cathedral ceiling has soffit vents on both sides. When the roofer replaced the roof 2.5 years ago, they did not reinstall the last 20 feet of ridge vent, over the outdoor patio and 10 feet into the livin
  3. Yes, the house has lots of gutters. I may need more. Many thanks!

I then started reading that mold from condensation was more likely to form on cold roof surfaces in Chicago than a warm room in Houston. Thank you for your experience, I will get the humidity monitor today. Th
  6. I am a homeowner in Houston, Texas. I have a vaulted roof in my living room with no attic space above it. The home is 20 years old, and the roof was replaced 2.5 years ago. In the last few months, we noticed mold forming on the cross beam that spans the length of the vaulted ceiling. I called the roofer, who suggested water is getting in through the ridge vent as there is a valley two feet above the vent that empties onto the ridge vent. The explanation makes sense as the mold inside the house corresponds to the impact side from the valley above the ridge vent. The roofer denies
