How to Silver a Roof

Wait for a sunny day when temperatures are 50 to 110 degrees Fahrenheit. Place a ladder next to the building and carefully climb up onto the roof. Sweep the entire surface of the roof to remove any dirt, leaves and pine straw.

Scrub all dirt and stains from the surface of the roof, using a pressure washer or garden hose and a push broom. Allow the roof to dry completely before proceeding.

Open a can of silver roof paint and pour some into a paint tray. Insert a roof roller with a 3/4-inch nap into the paint until it is saturated. Roll the paint onto the roof in a thin, even coat until no part of the underlying roof metal is visible. Overlap each stroke in multiple directions so you don't skip areas. Start painting at the part of the roof furthest from the ladder and work toward it.

Allow the paint to dry for 24 hours and apply a second coat of silver in the same manner to ensure adequate coverage.
