Radical Roofs

Overview

Objectives/Goals The purpose of this project was to determine the thermal conductivity of different roofing materials. I believe that slate will have the most drastic effect on water temperature because it is the densest material. Methods/Materials Four 2 foot x 2 foot roofs each using a different roofing material were constructed and placed on four 2 foot x 2 foot x 3.5 inch boxes filled with water three centimeters high. The roofing material used was slate, composite, and wood. On the fourth roof, no actual material was used except for what was used under the other three roofs (tar paper and plywood). Four thermometers measured the water temperature of each box over a period of eight days. Another thermometer measured air temperature. Results The experiment indicated that the amount of direct sunlight on the roofing material had a larger impact than a varying roof type. Conclusions/Discussion My conclusion is that slate had just the same effect on water temperature as wood and composite. All roofing materials had the same effect on the water temperature.
