We do that any time we replace underpinning on a home. Some people might say it looks tacky, but I promise you it looks 100 times better than having 1) tall grass and weeds growing next to the underpinning, 2) dead tall grass and weeds next to the underpinning (tenant sprayed with weed killer and left it); or 3) hundreds of small holes in the underpinning caused by weed eating around the skirting over the years.
Just buy the cheapest shingles you can find, flip them upside down and put halfway under the home, with the other half outside the home with the ground channel sitting on top to hold it down. Very simple. Even buying new shingles should only cost $75 per home (3 bundles per home typically).
