Do you have gas-powered appliances in your home? If so, your attic's venting system is set up to remove carbon monoxide and other dangerous gases from the air through the roof. Sometimes bad hail storms or tornadoes can jar or damage the connections between the gas-powered appliances and your roof's venting system. Even some repair jobs could lead to increased carbon monoxide poisoning risks if not all connections are put back into position. Be sure to take these precautions before having your roof repaired to keep your home safe for you and your loved ones.
