The review of roofing materials provided in ASAP ROOFING’s article, Re-Roofing The Green Way,should have provided you with a feel for the types of materials available, and their sustainability. Now, we can look further to consider a few more factors that influence a roof’s greenness.
Recycled Content. In terms recycled content, a key factor is durability, as regardless of the percentage of recycled content a roof may contain, if it needs to be replaced before another, more durable alternative, the environmental benefit of recycled material is mitigated. Therefore, it is best to consider both recycled content and sturdiness. Another factor to be considered is whether or not the material can be recycled again at the end of your roof’s lifetime.
Coatings. In the right conditions, such as a hailstorm, almost all roof coatings, can wash into water sources and become dangerous to aquatic life. The two to be most careful of copper and zinc.
Maintenance. Hopefully little maintenance will be required of your roof, however, in some cases, chemical sprays or coatings will be recommended to preserve your roof’s durability. Double check to make sure that no toxic materials will be required to maintain your roof.
Weight. The weight of a roof is directly proportional to the strength of the foundation (your home’s structure) on which it sits. If your roof damages your home’s framework because it is too heavy, not only will you have additional repairs to do, but additional materials will be required, which places increased environmental load on the overall cost of your roof.
Roof Slope. The roofing material that you choose will be influenced by your roof’s slope. Check to be sure that you are choosing a material that is indicated for the slope of your roof.
Color and Reflectivity. For hotter climates, or climates with a significant amount of sunny days per year, a lighter colored roof will help keep energy costs low. For cooler climates, or climates with few sunny days, the opposite is true, and darker colors are better.
Warranty. The longer the warranty, the more sustainable a roof is. Although sometimes roofing materials with a long warranty can be more expensive, they will pay off in the end.
As with any aspect of roofing, ASAP ROOFING is here to help, and can advise you on the best, most sustainable roof choices for your home.
