Just two days ago this house was set on its foundation. By the way, isn't the roof color just awful! It is a waterproofing material that goes on the roof under the roof shingles. This is an extra layer of protection and just one more example of how Vermont Modular does it better. And, do you notice how the awful green roof clashes with the other color green of the house! That exterior plywood sheathing is an up-grade; we use only The Advantech ZIP system to keep your house both water proof and wind proof. Oh did we mention that both the waterproof membrane on the roof and the Advantech ZIP are standard with a home from Vermont Modular Homes. We do it so well.
