As more and more Hawaii homes and businesses are looking into solar installation to help fight rising energy costs, the number of homes and businesses switching to solar panels is on the rise for both residential and commercial properties statewide.

Before installing a solar panel array, it is important to assess the condition of the existing roof. By ensuring the integrity of the existing roofing system, you will avoid future problems such as leakage, repair or the need to remove panels to re-roof. Certain types of roofs, such as tile and shingle roofs, can present challenges to the solar contractor like cracked tiles or loose shingles. By having your roof inspected and getting the necessary repairs prior to solar installation, you ensure that your roof is in proper condition for solar installation and is less likely to cause you problems in the future.

Your existing roof’s warranty is another important factor to consider. Knowing the warranty of an existing roof is vital when deciding to go solar. If the warranty will expire soon or a homeowner has experienced persistent leakage, it is a good idea to install a new roof before making the investment for solar. Removing solar equipment to make repairs to a damaged roof can be quite costly. Therefore, it is important to know how much longer you have until your warranty expires, so you can make the best decision.



An inexpensive way to enhance the integrity of the substrate (roofing surface) on your flat or low-pitch roof is through the installation of a coating system. This watertight system ranges in price from roughly $3 to $5 per foot and holds material warranties ranging from five years to the lifetime of the structure. It is advantageous to coat your roof prior to solar installation because this creates a watertight membrane that will not allow water to penetrate and cause leakage in the future.

For steeper roofing surfaces, asphalt shingles are a great option. They also are cost-effective and have many great warranty options from 20 years to the lifetime of the structure. Pricing for this roofing system ranges from $3.50 to $5.50 per foot.
