CLIMATE ZONES FOR ROOF SYSTEMS

Climatic conditions vary considerably over the United States forming similar climatic divisions which when grouped together form climatic zones. The National Oceanic and Atmospheric Administration (NOAA) defined these regions within a state that are as close to the same climatic condition as possible. Each NOAA Climatic Division is placed into one of five climate zones. Based on its 30 year average heating degree-days (HDD) and cooling degree-days (CDD) for the period from 1971 through the year 2000. This database is continually updated. Based on this knowledge, roofing materials for the specific climatic zones are recommended by the manufacturers. The Roof Guys are taught these technical recommendations and hold to these standards when applying your roofing systems.
