Over time, roofs collect dirt, moss, algae, and streaks that not only ruin curb appeal but can also cause damage and shorten the lifespan of your shingles. At Blue Wave Exterior Cleaning, we use chemical treatment applied with a low-pressure soft washing system to safely and effectively restore your roof’s clean, like-new look.

Moss, Lichen, and Algae can all grow on your roof. The rough texture of a shingle both helps them bind on, and retains more moisture than a smooth surface would. This texture comes from the mineral granules which often contain lime that mosses use as a source of nutrients, damaging the shingle in the process.
How we Clean Roofs: When cleaning roofs, we use a soft wash method to gently remove algae, moss, and stains without damaging shingles. This involves a chemical treatment to kill organic growth down to the root (which is technically called a rhizoid in the case of moss, or a holdfast in the case of lichen). We don't ever pressure wash shingles (and you shouldn't either) because shingles are soft and pressure washing can severely damage them by knocking off protective granules or even tearing shingles. This safe, soft process is one of many factors that separate a professional company like blue wave from a handyman with a pressure washer who may damage your roof.
When You Should Get Your Roof Cleaned: There are obvious signs that your roof needs to be cleaned like the presence of black splotches/streaks or large patches of moss/lichen which are visible from the ground. Unfortunately, moss growth that is harder to spot will also affect the longevity of your roof. It often grows at the seams where shingles meet, and can be difficult to spot. The only way to know for sure is a close examination of your roof.

FAQ
How long will it take to see results?
How long will it take to see results?
After a roof wash you will notice an immediate difference. By the time our technician leaves your property, the dark green moss will have turned white or grey, singling that it is totally dead. Black streaks from algae may appear to be totally gone, or may turn yellow-brown. Either way, a portion of the organic growth, particularly larger clumps of moss, will still be on the roof. Rest assured, these are dead, and just need a little more time to release their grip on your shingles. They will fall off (generally during a rain storm). This will take a few months at most, but is generally far faster.
Why do you not blast off all the moss on the day of the cleaning?
Why do you not blast off all the moss on the day of the cleaning?
A portion will roll off immediately, but some of the moss and lichen will be securely attached, and applying enough force to dislodge them would damage a roof.
