Nothing is as frustrating as an unexpected roofing problem and especially so during winter weather. It's an issue which has to be addressed immediately regardless of whether your schedule allows you the time to deal with it, otherwise, what starts as a simple repair becomes worse. Water leaks left unattended cause rot and mold to your building's structure and the damage will continue to spread for as long as the leak remains. Fortunately, there are ways to keep the odds of a leak forming to a minimum, and by doing so you build a relationship with a contractor you can trust to fix the problem should it arise.
