Homeowners Susan and Tim Fitzhugh have had moisture problems ever since they built their home 15 years ago, including leaks in the metal roof and problems with the shower leaking behind the bathroom wall, which had resulted in mold and mildew problems.
Repair Metal Roof Leak
The roof on the Fitzhugh’s house had been leaking for years where three slopes of the metal roof converge and drain onto a flat section of the roof.
The first step in fixing the roof leak was to remove the accumulated leaves and debris and trim the trees and shrubs away from the roof.
To find the leak, Allen went in the attic while Danny sprayed water on the roof from a garden hose. Communicating back and forth by cell phone made it easy to see where the water was getting in.
Once the roof was dry, the gap in the roof was filled with Titebond Metal Roof Sealant, which is specifically designed for metal roof applications.
Bathroom Shower Leak
In an attempt to stop the shower in the master bathroom from leaking behind the wall, the original tile shower had been removed and replaced with a cultured marble shower surround. In spite of all their efforts, however, the shower continued to leak.
To find the problem, a piece of baseboard was removed and an inspection camera inserted in the wall while the shower was running.
The leak turned out to be around the shower faucet trim plate. To fix the leak, a new trim plate and gasket were installed to seal the faucet tightly to the wall.
To remove the mold that had accumulated in the bathroom, Wet & Forget Indoor Mold+Mildew Disinfectant Cleaner was sprayed on the surface and wiped off after 10 minutes.
Install Bathroom Vent Fan
Since there wasn’t a vent fan in the shower area of the Fitzhugh’s bathroom, we installed a Broan ULTRA GREEN™ Humidity Sensing bath vent fan (model ZB110HL) with built-in light in place of the recessed light fixture over the shower.
The fan included a humidity sensor that turns the fan on automatically when the humidity in the bathroom is high and off when it returns to normal levels. The fan was vented through an outside wall using 6” duct.
The vent fan in the bathroom water closet was never vented to the outside, and moisture in the attic had damaged the insulation. To fix the problem, we vented the water closet fan to the outside through the attic gable wall.
The damaged insulation was removed and replaced with Roxul stone wool insulation. Stone wool insulation repels water, won’t contribute to mold or fungal growth, and is highly fire resistant.

Asphalt Roof Replacement Test
An asphalt shingle roof is both inexpensive and durable. To tell whether your asphalt roof needs to be replaced, slowly bend one of the shingles back. If the shingle is brittle and breaks, it’s probably time to replace the roof. (Watch Video)
