I could really use some advice; my friend recently had a swamp cooler installed. This swamp cooler stands on 4 support legs, the feet of the legs resting directly on the shingles (asphalt) of the roof (pitched). The problem is that due to the weight of the coooler, one of the feet is pushing through a shingle, creating a leak. How can I correct this situation so the foot has some support and is not directly damaging the shingle? My thought was sheet metal, but not sure if sheet metal should be placed underneath the shingle or directly underneath the foot of the cooler leg. Advice? Anybody else have experience with this situation?

As a roofer, I have probably uninstalled and re-installed hundreds of them.

This was not installed correctly. Your friend should expet the installer to make it good even if small claims court to cover expense.

The legs should not sit directly on the shingles. There should be a 2" angle iron at least 12 gaauge that provides a foot on the roof on each side.

You'll have two short legs on the uphill side and two longer legs on the downhill side. The angle iron foot runs up/down the roof long enough to connect the two. The legs are connected to this with machine bolts to the verticle side and the other part of the angle sitting on the shingles to spread the load over all the shingles

Excellence is its own reward!
