All roofing systems will meet the requirements of the 2012 International Residential Code and the manufacturer’s installation requirements. Highlands Ranch will not be required for roof systems to meet high wind requirements or severe climate requirements on properties under 7000 feet in elevation. It is of our opinion and experience at Integrity Roofing and Painting, LLC that all roof systems should be installed to meet high wind requirements, therefore we believe it is of utmost importance for applicators to install 6-nails per shingle. Roof systems shall not exceed 600 pounds per square. A square is 100 square feet of roof area.

However, if you look at the International Residential Code for 2012 you’ll find that if the property has a history of ice dams, ice and water shield will be required.
