A cool roof is one that reflects heat. This helps to keep your home cooler in the summer heat. If you live in a hot and humid environment, this can dramatically reduce your cooling costs. These tips can help you get a cool roof if your roof is causing too much energy gain.

1. COOLER MATERIALS – CHOOSE

Certain roofing materials reflect heat/sunlight better than others. A built-up roof is an option for low-slope roofs. It is made up of various layers of fabric reinforcement. Reflecting mineral granules help to redirect light. Other popular options include modified bitumen sheet membranes and spray polyurethane roofs.

Metal, tile, and shingle are all great options for steep slopes. Asphalt shingles are made with small granules which reflect the sun. To reflect heat and light better, it is best to choose lighter-colored shingles. Clay tiles work well in hot climates, as they allow for little airflow between them. Reflecting light is also possible with last painted metal roofs.

2. Add a reflective material to existing roofs

You don’t need to replace your roof if it is in good condition. Retrofitting your roof can improve the energy efficiency of almost any roof. Retrofitting is simply adding reflective coatings to your roof.

You can add this material to any type of roof, including metal and asphalt. Ask your roofer to add a reflective coating to increase energy efficiency properties if you’re installing a new roof.

3. BUILD A GREY ROOF

A green roof is a great option if you’re environmentally conscious and want to lower cooling costs. Most importantly, you should remove any plant matter (like moss) that has grown on your roof as soon as it becomes visible to avoid further damage. A green roof, however, uses plants as its roofing material.

This works best on flat roofs but can also be used on low-sloped roofs. You can add as few or as many plants as you like. The plants absorb a lot of sunlight before it reaches your eyes. The plants also absorb water from rain, which helps prevent water damage to your home.

4. ADD SOME INSULATIONS TO THE ATTIC

After you are certain that your roof is reflective, it’s the right time to increase insulation in your attic. Any heat that passes through your roof will be absorbed into your living spaces. You can increase insulation to keep heat out of the attic or outside and reduce the energy required to cool your home.

Spray foam insulation is a popular choice because of its high effectiveness. Spray foam insulation expands when it dries. This allows it to reach every corner of your attic to completely cover it. You don’t necessarily have to use the same insulation, but any insulation can help. You can increase the insulation value by adding loose fibers to fiberglass batt insulation or spray foam.

It is important to choose the right roof for you. If you live in a climate with high heat or humidity, a reflective roof will be the best choice to keep your energy costs low. There are many options available to keep your roof cool. Contact us for more information on roof repairs or installation.
