It seems that more and more homes that are requesting solar hot water systems are coming equipped with metal roofs.  A solar system installed on an asphalt shingle is challenging enough when it comes to getting on the roof and keeping your feet under you.  A metal roof adds a little more challenge to that issue.  An experienced solar installer offered me this tip: the next time you need to get up on a metal roof bring a bottle of sprite.  Shake the bottle and then spray the metal roof where you will be working with the sprite.  The sugar water will dry on the roof creating a tacky surface that will make it much easier to maintain traction while you are working.  The sprite will not stain the roof and will wash off the next time it rains.

Any time you can have an extra measure of safety while you are working on the roof you want to take it.
