Greenwich Roofing: Article About Benefits Of an Energy Efficient Roof
The good news for homeowners is that boosting the energy efficiency of a roof doesn't have to cost a small fortune. There are steps that can homeowners can take when selecting roofing materials and making improvements to their existing roof that may result in lower utility bills and accumulated savings over time. A Greenwich roofing professional can help a homeowner determine where to get started by assessing the condition of their existing roof.
When it comes to replacing shingles, homeowners can boost energy efficiency by opting for shingles in a lighter color like gray or white. A darker colored asphalt roof can easily reach 150 degrees or more on a hot day, resulting in added heat transferring down into a home. The added heat makes cooling systems work harder to maintain the desired indoor temperature on hot days. A roof with shingles in a lighter shade can be as much as 50 to 60 degrees cooler on an especially hot and sunny day, translating to lower utility costs over time.
Increasing the energy efficiency of a roof system includes taking a look at the quality of the insulation that a homeowner has within their attic. An attic with little or no insulation can compound problems a homeowner may already have from a roof that's also poorly insulated. Home insulation solutions range from replacing old insulation with a newer product, opting for home foam insulation or going with cellulose insulation. One exception to roofing being greatly affected by attic insulation issues is when a homeowner has a metal roof, which has a higher heat reflectivity than other roofing materials, rather than a traditional asphalt shingled roof.

If a homeowner is moving into an older home, increasing energy efficiency starts with taking a look at what's going on with their current roof. For instance, a reroof where only the surface is replaced, isn't recommended for a roof that's already 30 years old with a history of previous repairs. Even an older roof that's in decent shape is likely to need some updating, especially since roofing materials from even just a decade ago aren't as efficient as what's on the market today. Certain roof coatings can also increase a roof's ability to reflect heat.
Flashing is another possible source of decreased energy efficiency on a roof. Metal strips that have become worn around chimneys or skylights, for instance, can allow cold air to get into a home through the roof. Even if worn flashing isn't causing leaks, air can come into a home if there's insufficient insulation and caulking around areas of a roof where flashing hasn't been properly maintained.
Roofing professionals can also help homeowners spot signs of accelerated weathering that may make parts of a roof less energy efficient than the rest of the roof. Replacing outdated roofing materials and making minor repairs can further boost the energy efficiency of a residential roof. The final step a homeowner can take in their quest for added efficiency is to schedule regular roof inspections.
