Jeff is the nicest guy you will ever work with. He explained in detail all the work that would be involved in the replacement of a “roofer installed” previous unit. His price was more than reasonable and he even provided photos of the entire installation as I wasn’t about to climb up and look close, due to a previous mishap the last time I inspected (note to all: let the pros do the roof work) The installation was perfect. When researching for the installation I found that skylight installation is something not just any roof or window installer will do correctly. Best to hire a skylight specialist for skylight installations.
