“In today’s world service is everything. With that said, Langer Roofing has provided us with exceptional service over the years. Whether it is their super emergency response or our yearly maintenance review, the Langer crew has never failed us. Gary and Matt field our calls and and dispatch to our needs – typically the same day. We all know roof leaks can be very elusive but their experienced tech Jeff has always hit the mark. We recently had remodeling of the building in March which resulted in rooftop work. Unfortunately some construction workers were not diligent and had left debris which eventually caused failure of our rubber roof causing several different leaks. Langer to the rescue!! I have been the Facility Manager in our buildings since 1996 and I just can’t say enough good things about Langer Roofing.”
