3 Great Ways to Make Your Home Roof More Energy Efficient

1) Cool your roofing system

“Cool” roofings are lighter in color than conventional black asphalt or dark wood shingles and save energy by reflecting light and heat away instead of absorbing them. This is known as “the albedo result,” and numerous research studies have recorded substantial energy savings from simply lightening the color of a roofing.

The issue with dark roofing systems: The temperature level outside might be 95 degrees, which is plenty hot, however your dark roof is conducting a much greater temperature level down toward you and your household, making the rooms listed below hotter and forcing the a/c to work harder, as Barbara Collins explains in her answer to the Ask A Pro concern “NYC has a ‘cool roof’ program. Exists a white paint or finishing to make my roof cooler?” In New York City, she notes, a dark-colored asphalt roof can reach 150 to 175 degrees on a hot summer day. This not only increases the energy requirements of your house, it likewise contributes to the heat island result in city locations.

The benefits of cool roofs: A cool roof, on the other hand, can be 50 to 60 degrees cooler than a conventional dark-colored roof, decreasing the cooling load on your house, saving energy and lowering utility costs. By reducing the solar gain and heat retention of your home, a white roof also increases its comfort and reduces the heat island impact to which your house’s dark roofing system contributes.

– How to cool your roofing: The most convenient route is to slap a cool roofing system finish onto an existing roofing system. If you’re currently re-roofing, or developing a new house, think about changing shingles or asphalt with lighter-colored versions. If you have a flat-top roof  recommendations would be to add DuraLast’s sheets of fiber-reinforced white PVC membranes. A quick search of the Cool Roof Rating Council’s Rated Products Directory will supply you with performance data about different roof items. Products are rated for their reflectiveness: the greater the number, the more reflective the product is, and the cooler your roofing will be.

2) Insulate from below

Insulation is among the first things people think of when they go about making their houses more energy-efficient. According to the Rocky Mountain Institute ( RMI), the attic is usually the top priority, due to the fact that setting up insulation there is easy and provides instant advantages. When insulating the attic, it’s important not to forget about the roofing. Regrettably, deciding on the finest insulation isn’t really always so uncomplicated, but our experts have recommendations on everything from the materials you must consider to how they need to be installed.

 – The problem: Roofs are your cooling and heating system’s greatest headache. An improperly insulated roofing will need more a/c in the summertime and more heating in the winter season, and will make your attic uneasy for use as a bed room or research study. Even if you do have insulation, it may not be enough.

– The advantages of insulation: A well-insulated roofing, on the other hand, can nearly negate the requirement for either mechanical system and will drastically lower your heating and cooling needs (in addition to your electrical power expense and your home’s emissions). Mick Dalrymple, in his answer to the question “What kind of roofing should I pick in a hot environment?”, describes how his roof’s insulation and weatherization finishing’s make air conditioning unnecessary up until outdoor temperatures reach over 100 degrees in Scottsdale, Arizona.

– How to appropriately insulate your roofing system: The material you choose will depend heavily on the kind of home you have and the climate you live in. Our professionals have recommendations on everything from the more modern options such as house foam insulation ( even a cogent answer to the open cell vs. closed cell foam argument) and cellulose insulation to simpler choices such as fiberglass or cotton batting. Those with open beams (particularly cathedral ceilings) in cooler climates should also consider a glowing barrier– easy reflective movie that twists around beams and shows heat rather than absorbing it. No matter what material you select, leaving an air space between the insulation and the roof product is usually a smart idea. Although in really dry climates, and with some metal roofing, it might not be needed, an air area will generally minimize the possibility of wetness getting caught in either the structure or the insulation and triggering mildew or mold to grow.


3) Re-roof sustainably

Whether you’re putting a roof on a new house, or re-roofing an existing residence, it’s a golden opportunity to do things as sustainably as possible. However with brand-new, apparently green roofing products concerning market each month, it’s tough to separate the great from the greenwashed.

– The problem: You wish to select a roofing system that lasts a long period of time, improves your home’s effectiveness and comfort, and lowers the heat island effect. That perfect roof material will move depending upon where you live and the sort of home you have, however our experts concur that wood shingles are probably not going to cut it no matter where you live, mainly due to the fact that they deteriorate rather rapidly and it’s not sustainable to replace your roofing every 15 years.

– The advantages of sustainable roof products: Simply choosing the best product might result in as much as a 30 percent decline in your house’s energy requirements. Whether that winds up being a metal roofing system (which is usually more pricey, but does deliver meaningful energy cost savings), tile roofing system, asphalt shingles, concrete or perhaps wood, all of our experts recommend reflective coverings to make your roofing cool. Elastomeric roof finishes not just reflect heat, and therefore conserve energy, but they can likewise extend the life time of your roofing system.

– How to sustainably re-roof your home: Any decent roofing professional needs to have the ability to recommend you on the very best roofing material for your home type and environment, but it’s a great idea to have a grasp of the fundamentals prior to talking with an expert. As soon as you’ve got a strong understanding of the conditions facing your roof, you’ll have to consider both roofing products and sheathing. If you’re taking the roof down to the rafters, especially if you live in a cooler environment, think about installing a sheathing with a radiant barrier– a laminated sheet of aluminum that will show heat into your house instead of absorbing it.
