Short-Screwing a Downspout

We recently were asked to look at downspout which had recently fallen from the house. You can see below what I am referring to. (I hate ending sentences with a preposition.)

Looking closer, we found the gutter contractor used a 1/2" screw to hold the downspout pipe band to the house. There were 3 pipe bands securing the downspout, but unfortunately each one only had a 1/2" screw as you see below.

The best fastener for this application would be a 1 1/2" zip screw. Needless to say it provides a "better bite" into the corner post.

You can check your home's downspouts very easily. Simply hold the downspout and give it a gentle pull. If there is not any movement or wiggle, you know they are secure.
