For the code in michigan. You know what I found? First edge of your roof then use the time clock in the bottom row unless your eaves hanging over your house more then 2 or 3 feet, use two rows of the same. Then the role of the rest of the house. If you have any valleys use weather watch or also known as ice and water. Then you need to start a row in the bottom of the cover. Then six inches Stagger your shingles, which will look like a stair step. Also make sure you have adequate ventilation, so most of the roofs already so be sure to replace with new vents. Nobody likes the old and used. If you have 3 tabs, trash, but if you put in them will also be a box on the rapper, but I would not recommend those stupid tiles. The architecture is not much more.
Demonstrate how the torch applied modified bitumen membranes felt insulation installed with high performance to create a warm roof construction.
