We still have a few bugs to work out with the data logger and then how to present the data on the blog, but here is the chart (in degrees F - note Celsius is coming soon) for the first full day, April 7 - April 8th.
What is interesting is the magnitude of difference. The decking under the asphalt shingles heats up much more quickly during the day than the decking under the green roof. The inverse is true at night. Though at night the decking temperatures become much closer in range, during the day the spread is significant.
Yesterday was partly cloudy with times of full sun. Outside air temperatures ranged from the upper 50's F for lows to high 70's for the high temperature.
As you can see all three green roofs used for data collection produced the same basic temperature profile curve, though the shed was slightly lower (due to the presence of some shade).
We will be refining the data presentation as time permits. Be sure to check back to see how these profiles develop over the late spring, summer and then into the fall and winter.

asphalt shingles are susceptible to corrosion and algae growth and are capable of tearing and flying away during heavy winds and rain. Plus, they can weigh five times more than metal panels per square, putting more strain on the foundation and structure of your home.
Asphalt shingles are eco-friendly, economic. Best for all kinds
Having a top quality roof is one of the most essential construction processes for a house. Getting this done is not a work for any remodeling firm or construction contractor but is a task which should be given to a professional and commercial roofing company.
