There are several options when choosing a glazed door. For maximum light, consider a door with a large glass area. For privacy and security, opt for one or two small sections of glass, or glazing that is decorative and obscures the view into your house. If there is a possibility of ultraviolet (UV) damage to floors, rugs and furniture, consider choosing a glazing that resists UV rays.
When installing roof shingles, do not nail above the sealant strips or the mid-section of the shingle.
