Roof Cleaning for All Roof Types

The alluring tropical climate makes Hawaii both a pleasant place to live and a dream destination for tourists from all over the world. On the flip side, the ups and downs of this tropical weather can wreak havoc on property, especially roofing materials that take regular beatings year after year. The team at Roof Restoration Hawaii is ready to ensure your home or business roof is in good shape to weather the next hurricane season, starting with the right type of roof cleaning for your roofing materials.

Asphalt Shingles

In humid and tropical climates like Hawaii, it is not uncommon for moss to start growing on asphalt shingles. Typically, these shingles are resistant to moss and algae growth, but growth can happen, particularly when debris builds up. Depending on where the moss begins to grow, it could lift individual shingles, making it easier for debris to collect in hard-to-reach areas and even weakening spots on the roof.

Asphalt shingles are a long-lasting roofing solution when maintained properly. A thorough cleaning every few years can help the roof to last longer, but it must be done correctly to avoid damaging the shingles. Pressure washing shingles can strip them of their asphalt layer, reducing their lifespan. Our team uses people-safe and pet-safe products that are tough on the stains and debris while offering a thorough clean to keep your asphalt roofing in better shape. If you are noticing streaks and discoloration on your shingles, it may be time for a cleaning.

Flat Roofs

Thermoplastic polyolefin and polyvinyl chloride, known as TPO and PVC respectively, make up the flat roofs often found on commercial and public buildings. This roofing style is beneficial because of its affordability and how easy it is to access and maintain. On the other hand, it is also easier for rain and debris to collect in areas because of the lack of sloping.

Most flat roofs are not designed for a lot of foot traffic, so it is a good idea to have professionals handle the cleaning and maintenance. A thorough cleaning at least every three to five years can help your flat roof last longer.

Wood Shake

Wooden roofing has great curb appeal and is stronger than it looks. The shingles are usually thicker than regular asphalt shingles, which also makes it naturally tough and great for insulating. However, being made of wood, it does have some susceptibility to water damage when not properly maintained.

You know it is time to clean your wooden shingles when they become dull or discolored. Like asphalt shingles, discoloration on wood shake can be caused by moss and algae growth, which is more likely to occur when there is a buildup of organisms and debris on the roof. While it may seem satisfying to pressure-wash cedar and other wooden shingles to get that bright, fresh look, it can cause warping and other irreparable damage when done improperly. Our products are safe to use on wooden roofing and can help restore the look of your shingles without causing excess wear.


Tile roofing is a superb choice for fire resistance and weathering tropical storms. It is one of the longest-lasting roofing options, and when installed properly in the right climate, it may last anywhere from 50 to 100 years. Tile roofing is also easier to maintain and repair. It discourages the growth of moss and algae and the invasion of pesky insects. However, it tends to require cleaning more frequently than other types of roofing.

High-pressure power washing can damage the tiling, so it is a good idea to go with a soft power wash every couple of years. This is best left to a professional team with the equipment and the know-how to rejuvenate the appearance of your tile roofing while providing a thorough cleaning.
