Clip Summary
Bob meets carpenter Bob Ryley, who is putting sidewall shingles onto the exterior of the new addition. Bob points out the newly trimmed window and the ten-inch-wide piece of felt around it, a "spline". The spline is common in the Northeast. It helps prevent moisture from entering spaces between the trim and the shingles, once shrinkage has occurred.
