This is a cool roof installation we did last year-starting with Thermax insulation board with a radiant foil backing over the existing asphalt shingles and furring strips vertically over the rafters.

Then we install furring strip(1x4) horizontally `over that. This gives you toe boards as well, and facilitates air flow from ridge to peak.

Here we are putting on the ridge cap with a little rigde horse we made for this purpose.

The chimney is usually the last to get finished...
This is an energy saving installation as it cuts the heat load tremendously and is covered by a 30% tax credit this year. A very good investment at about 3 dollars a square foot for labor and 10 dollars a square foot for materials.
