How to Install a Rain Diverter
Last spring, I called our air conditioning specialist to check out our outside unit. After his inspection, he informed me that discoloration on the surface had been caused by rainwater running off the roof into the unit. Additionally, he informed me that runoff pouring into the unit could be a problem if we ever got any more rain.
I had no clue what a rain diverter was. He explained that it was in the shape of an inverted “V” and fit under the shingles of my roof. I thanked him for the advice and promptly forgot about the advice. Well, a couple of Saturdays later I was watching the “This Old House Hour” on our local PBS channel. To my surprise, Tom Silva was demonstrating how even the most inept handyman could install a rain diverter in less than an hour. I watched with great interest.
I’ve purchased the material and will install my very own rain diverter after the holidays. I’m prayerful that installing one of these beauties will also double as a sort of “rain dance” that will bring significant spring showers.
