Every year it is the same New Year's resolution - eat better, work out more often, make more time to do the activities we enjoy. Well if you can stick to those resolutions for the rest of the year, more power to you! One thing you should do, however, is be responsible about the research you put into your 2011 roof purchase.
So you know nothing about roofing material and how to tell what is top rated and what isn't. A good place to start - ask the manufacturer for the testing summaries for their products. Manufacturers have their products tested by independent third parties, like the Underwriters Laboratories or ASTM International. So what do some of these ratings mean? I am going to speak in terms of simulated slate roofing material and simulated shake roofing material because, well, that is what I know. Here is a (brief) summary of some of the top things to look for.
1. Fire Rating - Products are rated Class A, Class B, Class C, or unrated with Class A being the highest rating. For a roofing product, this basically means how long a burning brand can stay on an assembled roof deck and what the material's reaction to it is. A material like our slate alternative will pass the Class A test by allowing a burning brand to sit on the deck for at least 90 minutes without burning through the tiles to ignite the deck. Also, the flame minimally spreads. Will a Class A product keep your whole house from burning down? No, but if a burning tree branch falls on your roof, 90 minutes could be the difference between the fire department saving your home or suffering a total loss. A Class A rating can be achieved with all of DaVinci Roofscapes' eco friendly roof tiles.
2. Impact Rating - Real life equivalent = "hail rating". This test is done by a 2" steel ball being dropped on the product from 20 feet in the air. This test is repeated twice and a rating of Class 4, Class 3, Class 2 and Class 1 assigned to it with Class 4 being the best. Again, having a Class 4 roof (like a DaVinci composite shake) may not mean much during those once in a lifetime hail storms where you think the world is about to end, but after the occasional seasonal storm you'll be thankful you made the investment.
3. Wind Rating - We don't all live on the coast with high winds off the ocean to worry about, but a storm carrying a 50 mph wind isn't too uncommon. You'll want to make sure your roofing material can withstand nature's strong wind gusts without tiles blowing off or flying in the air and not coming back down to lay flat once the wind has subsided. Our slate alternative carries a 110 mph wind rating.
