As trendy as they are for green building and demonstrably beneficial for energy savings

This must be the overriding intent of any installation protocols.<\/p>\n

Note that some roofing contractors warrant their work against leakage, and skylight installation should not compromise or void such warranties. When in doubt, independent installers should confer with the roofing contractor.<\/p>\n

INSTALLATION SUPPLIES<\/h4>\n

Proper installation begins with selection and use of the proper supplies\u2014notably sealants, fasteners and flashing.<\/p>\n

SEALANT SELECTION<\/strong>
\nIf sealants are recommended by the manufacturer, follow the manufacturer\u2019s specifications. When the manufacturer is silent about the use of sealants and the installation guidelines dictate their use, the following recommendations should be observed:<\/p>\n
