The weathervane arrived quickly great customer service it’s very well-made and sturdy. We’re installing it in the San Juan Islands of Washington where we get some Highwinds and I installed it on a brand new triple laminate Certainteed roof which is very thick and although the eight screws that are supplied are very good for a typical roof for a cupola mount for the ridge I opted for 5 inch carriage bolts with washers to include a rubber washer on the top to keep water infiltration into the garage attic. 5 inches wasn’t needed at all only really 3 inches was. I installed it on the ridge cap without a ridge vent because the garage has gable vents. The mounting device is extremely sturdy because I used bolts with nuts and washers I only used four of the holes that is 21 each side I thought the lower holes might be too low on my triple laminate shingles Plus the four bolts tighten down hold it sturdy enough for even 100 mile an hour wind. Obviously a great company extremely good communication and they take a lot of pride in their craftsmanship.It’s surpassed our expectations I will include some pictures of it on our brand new garage.
The garage is 30’ x 26’.
