I am looking for a general contractor or a roof specialist who has experience with installing roof attic fans. I have a one piece solar power attic fan that you have to cut a round section of your roof out to install it. Looks pretty simple but, I want to ensure that it will not leak and since I have never done this before, I thought I would offer the job to someone who has done this kind of work before. I am in Glen Allen, 23060 and pay cash or beer. If you are interested, PM me your asking price to do the install. Thanks.
