Weather vanes are popular decorative items today and you’ll find them in several different types of stores. We’ve seen good selections at antique stores, lawn and garden centers, and where yard sheds are sold. Wherever you find one, don’t forget to buy a mounting bracket to attach the vane to the roof. One type of bracket fits over the roof shingles, while another mounts on the sidewall at the peak of the roof. Some are designed to adjust and fit over a ridge vent. The mount is fastened to the building with lag bolts.

If you’re not afraid to work on the roof, you can install it yourself. You’ll need a ladder, electric drill and wrench. It’s handy to have a helper on the ground. If high-rise work is not your style, ask the retailer if they can recommend an installer, or hire a carpenter to do the job.
