Does Shingle Color Really Matter?
When it comes to shingle color, many people are of the opinion that esthetics has more bearing than functionality. Undoubtedly, lighter colored shingles will show dirt, grime, and age more pronouncedly than darker colored ones. However, according to the Florida Solar Energy Center (FSEC), shingle color does matter. Here are some of their findings:
• Black shingles have a 97 % solar absorptance while white shingles have 76 % absorptance. This makes black shingles 25 % hotter than white shingles at peak temperature. This suggests that black shingles should deteriorate faster than white shingles if high temperatures are a factor in their breakdown.
• White shingles result in better energy cooling costs than black shingles.
• Shingles of all colors are poor reflectors of the sun’s rays.
Therefore, shingle color affects the curb appeal as well as energy efficiency. It is important to note that whether an attic is sealed or vented also affects roof temperatures. Nonetheless, consider these factors when choosing shingle color:
• Since black or dark colored shingles absorb more heat, they would suit roofs in colder climates better. Snow will melt faster on these roofs than white or light colored shingles.
• Black shingles help houses in colder climates to stay warmer during winter months thus helping to reduce heating costs.
• Since white or light colored shingles are better reflectors of heat than black shingles; they are best suited for climates with high temperatures. This means that cooling costs for these homes will be lowered.
There is a lot that goes into the selection of the roofing material that is right for your job. Consult the experts before pulling the trigger, to be sure you are making the best decision possible.
