"Collecting Water From Asphalt Shingle Roofs"

I thought the best source of information was from the largest roofing materials manufacturer in the world.  They also produce the best selling "Timberline" series.

Before I share data from GAF, let me describe GAF to you from personal experience:  They are an honest manufacturer, fight fair, and have an extremely comprehensive line of roofing products.  I must praise them for telling you the TRUTH, and not trying to eke out one more sale through decption.

By now, you know I hold GAF, Firestone, Carlisle-Syntec in the very highest regard.  So let's answer your question:

SUBJECT: Reclaimed Water From An Asphalt Shingle Roof

Can I Reclaim Water (Collect Water For Use) Run-off From My Roof?

Yes… But you should only use this water for lawn, shrubbery, and flower irrigation since water run-off from asphalt shingles is not FDA approved for potable water reclamation or agricultural use.

What this means…is that because it is not FDA approved, the reclaimed water is not suitable for:
• drinking
• cooking
• bathing
• watering of fruits or vegetables for human consumption

What Should I Know?

Water reclaimed from a shingle roof… may present a variety of hazards that may affect you or your animal’s health. While the water may seem “clean”, consider:

• Asphalt is processed from crude oil and there are chemicals in asphalt that can be hazardous to your health if consumed.

• The granule surface can collect dirt and other air pollutants which vary by location… water running over these granules can collect the dirt and pollutants as it runs off the roof.

• Under the correct conditions, algae, mold, moss, and mildew can grow on the shingle surface. These fungi may be harmful to people and animals when introduced into a drinking water supply.

• Shingles may contain copper oxide, or other algae inhibitors that may harm aquatic life.

                               Where Can I Get More Information?

GAF-Elk Technical Services can assist you… with these and other questions you may have regarding your new roof installation. GAF-Elk Technical Services can be contacted at 800-ROOF-411 (800-766-3411). Also, the GAF-Elk website is a great resource for just about any question you may have or for additional information you may require. That site is at: www.gaf.com

So, now you've heard it from the "TOP", and don't have to depend upon hearsay.

You know those little "Rainbows" that form on asphalt pavement in puddles after a rainstorm?  They are not your friends.

The same principle applies to petroleum on the TOP of a structure, just like it does on the street.

Make sense?

I am researching the possibility of presenting an actual recording of my presentations here, as it may provide a more personal aspect to what we're trying to do.  If that's something you'd like to see and hear, please do let me know.

Thank you for spending time with me today.  I feel strong, mentally where I want to be, and most of all: HAPPY.

Respect each other.  Help each other. Encourage each other.

We will all be better for it.

I will encourage each of you to reject negativity in all forms, and remember to always keep looking "UP".
