To the person who left the low review because of their "A" frame house. You can't give a bad review because you have a 22 and 12 pitch roof. That is a very uncommon roof pitch. You can't blame a company for not having an off the shelf product for a pitch like that. Get one made for you and then have it installed, then review it. To the other guy who said it's not called a roof "jack". In different parts of the the country terminology is distinguished differently, however I have been roofing for 34 years from California, Arizona, Kentucky, Florida, Ohio, Tennessee, the list goes on. We still call them Jack's and boots. No reason to leave a bad review on here if you haven't used their products. I have been using their products for years on shingle and custom fabricated copper standing seam that we do and they are excellent and so is the customer service. 5 out of 5 stars from the Duke Boy's Exteriors! Keep up the good work!
