I am looking at purchasing a MetroShake roof. My existing roof is a worn out wood shake roof. Two contractors tell me they will tear off the roof and underlay with 30lb felt. The other, which is a larger contractor, claims he will not tear off and simply build a grid over the existing shingles. My question is.....what is the best way to do this???? Thank you for you input.

This question is rather proprietary to the Metro product. It is my general understanding that both methods are acceptable and can be done in accordance with building code. However, you should contact Pete Croft or Joe Wilson at Metro and confirm this and solicit their further input. Todd Miller
