Things You Can Do to Green up Your Existing Roof

These days, homeowners are looking for ways to improve the energy efficiency of their homes to reduce their utility bills. So they invest on improvements like caulking and weather-stripping windows and doors, installing a thermostat, using Energy Star-rated appliances and switching to low-flow fixtures among others.

All too often, however, many of them do not pay attention to their roofs when it comes to their energy efficiency efforts. Know that a huge part of the energy costs you are paying for each month literally goes through your roof. As your first line of defense against summer heat and the freezing temperatures of winter, your roof can significantly increase your energy bills if it lets too much warm and cold air into your house.

When that happens, your heating and air conditioning system has to work harder to keep your home comfortable, which in turn leads to high energy costs. Of course, the most effective way to green your roof is to replace it with a cool roof. However, this may entail significant amount of outlay, which you might not be prepared for at the moment.

Luckily, switching to a cool roof is not the only option to make your roof energy efficient. There are some simple improvements you can do today that will not require a huge investment, but will turn your existing roof into an energy- and money-saver. Read on to find out what those improvements are. Cover its surface with a reflective coating One major improvement to boost your existing roof’s energy efficiency is to cover its surface with reflective coating.

Simply put, a reflective coating can provide your roof with a sacrificial layer that functions by protecting its underlying substrate against the sun’s light and heat as well as from other punishments that the environment and weather doles out.

 Likewise, it can waterproof a leaky roof and reduce the effects of thermal expansion and contraction that could otherwise cause the failure of your roof’s fastener and seal. This in turn helps slow down the aging process of the roof, thereby prolonging its service life.

A good reflective coating can do more than extend the life cycle of your roof. When properly applied, it can also significantly reduce the temperature on the membrane by reflecting the sun’s heat back to the space. In fact, tests have shown that a reflective roof coating can reflect 60-85 percent of solar energy. That means lower heat for your home and lower cooling costs for you.

 Manufacturers have developed a wide variety of reflective coatings for roof to address multiple substrates that have different adhesion requirements as well as weathering characteristics. Hence, before you pick a coating for your roof, it is crucial to first identify the type of substrate you will be working with to ensure that you will get the right reflective coating and guarantee its long term performance.

Beef up your attic insulation doubling your attic insulation is another effort you can take to make your roof energy efficient. Adequate attic insulation does two things to increase the energy efficiency of your roof. During winter, the material keeps warm air from escaping to your roof.

This is important because warm air tends to rise to the roof, especially if there is no insulation in place, which in turn makes it difficult to keep your house warm and comfortable as the temperature outdoors drop. During summer, on the other hand, attic insulation prevents the heat coming through your roof from pushing down into your house.

As such, your cooling does not have to work harder to keep your home cooler. No matter what kind of insulation you currently have on your attic, a quick way to know if it is not adequate is to look across the space. If you notice that there are holes or gaps in your insulation or perhaps its level with the attic’s floor joist, you should add more.

 When adding insulation, it is not necessary to use the same type of insulation that you currently use in your attic. For instance, if you have fiberglass batts, it won’t be an issue if you add loose fill insulation on top of it. The most important thing that you have to do is to make sure that the insulation is evenly distributed across the space to maximize its use.

Add a ridge-and-soffit vent system don’t forget that a free flow of air is also necessary in the roof space to prevent heat and moist build-up in the home. When stale air does not escape the house, your cooling system has to work over time to keep your home comfortable, resulting to higher cooling costs.

 It can also condense on your attic and roof, which can damage insulation, wood deck, rafters, underlayment and shingles. To combat these problems, consider adding a ridge-and-soffit vent system to your roof. This will allow air to enter the attic at the soffit, travel under the roof sheathing where it takes away heat during summer and moisture during winter, then exit through the ridge.
