P.J. Fitzpatrick, Inc. will come to your home to find roofing leaks and fix them, most times, right on the spot before they become a serious problem. Some of the reasons for a roof to leak are: Improper Installation of Flashing on Chimneys, Skylights, Corners and Joins on your roof. Sometimes a bad contractor will not install a drip edge, which prevents water from running straight down your exterior walls when it rains. We provide professional analysis of your problem, tell you what we can do to fix the problem before we begin any work and then implement the work you approve of.
