The Flower Mound Fire Department has experienced a significant increase in carbon monoxide emergency calls. They are warning residents with newly-installed roofs that some vents aren't doing their jobs.
Roofs are still being replaced months after a hail storm damaged homes across North Texas.
"It just covered the back porch and looked like snow. Then, of course the roofers and contractors started coming around," Flower Mound resident Emily Cold said.
Cole was approached by multiple contractors wanting to replace her roof.
"There has been a lot of re-roofing going on in the town. We believe that when that happens, there is a large amount of contractors that come in from out of state and out of town to do the work," Flower Mound Assistant Fire Chief Fred Calhoun said.
Calhoun said it's important that residents double check newly installed roofs.
"If they [contractors] cover up a roof vent or if they disconnect a pipe running from the water heater to the attic, then it is an open ventilation. The fumes are going throughout the home," Calhoun said.
General contractor Jeff Berglund said homeowners should be on high alert to protect their homes from carbon monoxide.
"If a vent stack on a roof is secured properly, nothing should happen to it during the roof replacement," Berglund said.
Flower Mound officials say contractors must get a permit before installing a new roof in their town, and when the job is done, a town inspector will come by and do an attic inspection to make sure vent pipes are properly connected.
The Flower Mound Fire Department is also using the opportunity to remind residents it's also a good idea to install carbon monoxide detectors in your home.
