We follow Recommended cleaning methods from "ARMA" & "GAF" The top two Shingle manufactures.

Recommended cleaning methods from "ARMA" 

The most effective method of cleaning algae and moss from a roof is with sodium hypochlorite and water. Apply with a sprayer and allow the solution to dwell on the roof surface for 15 to 20 minutes, and then rinse thoroughly with water. Extended dwell times may be necessary, however, avoid letting the solution dry completely as this may prevent complete rinsing.

If a new roof is not an option, GAF recommends cleaning the roof with a special mixture. That mixture is: Sodium hypochlorite & water found at many home centers. Apply this mixture with a sprayer, let sit on the roof surface for up to 20 minutes, and rinse with water. Be sure to protect any shrubs below. Remember, the roof surface will become slippery when wet… be careful!!! For more information go to there website link

There are some steps that can be taken to discourage moss and algae growth:

  · Trimming tree branches back to allow more sunlight to reach the roof and minimize debris accumulation will provide an environment less inviting for such growth

  · Debris that does begin to accumulate on the roof should be cleared regularly with a leaf blower or similar, non-abrasive method as part of a regular maintenance program.

  · Air flow should be directed down the slope to avoid driving debris under the edges of the shingles.

  · Keep gutters clean to promote proper water drainage. Do not allow gutters from an upper roof to drain directly on a lower roof; extend the downspout from the upper roof into the lower gutter.

Other preventative measures —such as adding zinc or copper strips to prevent both algae and moss, or applying asphalt shingles that incorporate algae resistant copper granules —may be employed when it is time to replace a roof. Currently, there are asphalt shingles available that use algae resistance technology.

Adding zinc or copper strips to an existing roof is not recommended since this will require either applying the strips with exposed nails (which can cause leaks over time) or breaking the sealant bond (which may eventually result in wind damage) to slide the strips under the shingles.

Algae and moss growth on roofs, at a minimum, is an unsightly nuisance. Moss build-up can lead to roof damage or shingle blow -off if left unchecked. Keeping branches trimmed back from the roof and removing any debris that begins to accumulate should be part of a regular roof maintenance program. If moss or algae becomes visible, clean the roof with bleach and water mixture as described above to prevent the spread to nearby roofs.

Don’t let anyone power wash your roof – but don’t let them “non pressure” clean it either
Most homeowners are aware that you don’t want anyone cleaning the shingles on your roof with high pressure.  You obviously don’t want anyone blasting your shingles with 4000 psi.  But nowadays “non pressure” roof cleaning is touted by some roof cleaning companies.  Why?  Because they can clean roofs faster and cheaper if all they do is soak it down with a super strength chemicals, pack up your tools, and drive away.  This technique is great from a roof cleaning business perspective, but unfortunately leaving harsh chemicals to bake in the sun on your hot roof is not very good for the adhesive that binds the granules to the asphalt and fiberglass mat.  The “non pressure” super soak is NOT how the shingle manufacturers want you to clean it – ARMA specifically instructs us to rinse off the cleaning solution after it is applied. Bottom line, our roof cleaning process does NOT involve using high pressure, sodium hydroxide, or other super strength chemicals.  We only use the safest techniques and chemicals (as prescribed by ARMA) to achieve the best results for your roof, while taking care to protect your plants and prevent any damage to your landscaping. We 100% guarantee our roof cleaning service (excluding normal accumulation of dirt and debris).  This guarantee is meant to give you adequate time to be sure the job has been done properly and to your satisfaction.  If you are not satisfied with the work that was done for any reason, please contact us so we can make it right.
Roof Cleaning Facts

Remember the first time you looked up at your roof and noticed those black stains appearing on your shingles? Do you remember how you felt when you saw it slowly spreading across the roof? Your home was fairly new and your shingles barely a few years old. How could this be happening and what was causing it? Well, you weren't alone in your frustration. It appears that this is quite a common occurrence in Tennessee. Even on a roof with fungus resistant shingles, the fungus protection applied by the manufacturers of the shingles can begin to fail as soon as 2-3 years after installation. As the protection fails, staining can appear within six months. In Tennessee's hot & humid climate, it seems that inevitably a fungus actually begins to grow on your roof shingles; leaving behind these stains that continue to spread across your roof if left untreated. These fungi live abundantly in the soil. Like all fungi, they multiply by microscopic spores which float through the air and after landing on a hospitable surface, germinate. Fungi feed on organic matter such as wood, paper and asphalt, just to mention a few, and in the process, decompose and eventually destroy the material on which they grow.

Besides making your home look old and unsightly, researchers looking into this problem have discovered that this fungus could actually be costing you quite a bit of money. If your roof has fungus growth, temperatures under your roof become higher, increasing your monthly air conditioning costs and possibly even shortening the lifespan of your air conditioning unit. Some of these studies have revealed reduction of under-roof temperatures by anywhere from 10 - 20 degrees once the fungus has been eliminated. Some owners have seen utility savings of up to $20-$25 per month. In fact, there is a noticeable difference in your electric bill if the change in your attic temperature reduces the temperature in your living space by just 3-4 degrees. SHORTENED ROOF LIFE AND ALLERGIES.- Compounding the problem, the same studies seem to indicate that the lifespan of your roof is shortened by the increased granule loss from thermal expansions and contractions commonly experienced with this problem. This expansion and contraction can cause a weakening around the fastenings of the shingles on your roof. Also, unhealthy fungus spores and mold could conceivably be tracked into your home. For those owners suffering from allergies, this breeding ground on your roof could really cause some suffering.
