Florence Oregon Roof Cleaning

With an average of 160 rainy days per year, it is no wonder moss, algae and lichen thrive in the Florence Oregon and the surrounding Central Oregon Coast area. As a homeowner, it is essential that you understand what causes moss, algae and lichen growth and what the proper methods are for removing it, in order to prevent your roof from prematurely deteriorating.

We offer a wide array of roof maintenance services in Florence, the Central Oregon Coast, and  surrounding areas. When we inspect your roof, we will only recommend repairs and services that we are certain will benefit you. We never try to upsell unnecessarily.

Our trained experts clean roofs efficiently using top-of-the-line equipment and safely using state-of-the-art fall protection. Our professional and courteous teams are careful of landscaping and protect the integrity of your roof.

Asphalt Composite Roof Cleaning

If you have an asphalt shingle roof with a moss & algae problem, proper maintenance will be the difference between premature replacement and getting your full life expectancy. It may come as a surprise, but it’s not uncommon to lose up to 40% due to moss & algae, or improper cleaning.

Cedar Shake Roof Cleaning

If you have an asphalt shingle roof with a moss & algae problem, proper maintenance will be the difference between premature replacement and getting your full life expectancy. It may come as a surprise, but it’s not uncommon to lose up to 40% due to moss & algae, or improper cleaning.

Tile & Metal Roof Cleaning

Both Tile and Metal roofs are generally the most durable out of all roof types and require far less frequent cleanings, however they still need a good cleaning every 5-7 years to prevent significant algae build up and rusting. Our standard metal roof cleaning method is pressure washing, although we also offer to simply remove roof debris and clean gutters on a yearly basis if the customer desires.

Frequently Asked Questions About Roof Cleaning

WHAT CAUSES MOSS, ALGAE & LICHEN GROWTH?

A number of factors contribute to organic growth on your roof. The primary factors are:


MOISTURE

When moisture is consistently present on your roof, moss and algae growth is inevitable. Consequently, once moss begins to grow, it holds even more moisture on your roof, and thus, accelerates the rate of growth.

SHADE

The amount of sunlight each aspect of the roof receives determines how long moisture is retained after rainfalls. North facing aspects and heavily treed properties receive significantly more shade, and require consistent monitoring for signs of new growth.

PROXIMITY OF TREES

Trees in close proximity to your roof allow moss spores to be easily transported to your roof. They also provide shade. A roof on a heavily treed property will usually need to be treated once every year.

DEBRIS

Pine needles, leaves and branches all retain more moisture next to your roof. In many cases excessive debris buildup will create the perfect conditions for moss to grow.

WHY SHOULD MOSS, ALGAE AND LICHEN BE REMOVED?

SHORTENED ROOF LIFE:

Moss and algae (gloeocapsa magma) both retain moisture. As previously discussed, moisture increases the rate which moss, algae, mold and lichen grow. When moss begins to grow on your roof, the rhizoids (the root like anchoring structure of the moss) are embedded into asphalt shingles and use the inorganic material as a source of nutrients, causing the granular composition of the shingle to breakdown and loosen.

As granules are loosened, the core of the shingles is left exposed to the sun, causing the shingles to rapidly degrade. Once this occurs, the life of the roof can very quickly be reduced by up to ten years. Considering the average roof costs between $8000 to $12,000 to replace, we recommend a regular maintenance program to ensure your roof lasts the full length of its intended lifespan.

INCREASED PROPERTY VALUE:

When potential buyers first assess a house, a moss and algae covered roof is an immediate red flag. Considering the roof is a significant portion of the curb appeal of a house, a clean, well maintained roof is critical to giving buyers a great initial impression. Considering the replacement cost of a new roof and the reduced aesthetic appeal of the house, an unmaintained, moss covered roof can reduce property values by $10,000 or more.

HOW WE CLEAN YOUR ROOF

INITIAL CONSULTATION

Every roof we clean starts with a careful consultation with you to determine the best way to clean your roof. Every roof is different, with asphalt/composition tiles, cedar shingles, terracotta tiles, cement tiles, slate tiles or metal all requiring different approaches. The combination of contributing factors, the accessibility of the roof, and the extent of moss, algae and lichen growth all must be considered as well.

PREPARATION

Generally our process consists of carefully removing the majority of moss manually, using our custom built tools that allow us to gently lift the moss from the roof without causing damage to the granules. Due to the incredibly robust nature of the moss rhizoids, even dead moss will continue to cling to your roof. This step quickens the cleaning process and allows our treatment to be as effective as possible.

TREATMENT

Once the majority of moss has been removed, we treat the roof with our proprietary roof cleaning solution. Our treatment kills any remaining roots and the biocides and surfactants it contains continue work to keep your roof moss free. Our custom formulated solution is mixed specifically for your roof and is not commercially available. Unlike off the shelf products, such as Spray and Forget and 30 Seconds Spray and Walk Away, our treatment immediately kills roof moss and continues to clean the roof well after the initial application. Our treatment is approved by the Canadian and American Asphalt Shingle Manufactures Associations and the Roof Cleaning Institute of America.

The result is your roof is restored to looking new, with the absolute minimum amount of granule loss. Unlike pressure washing or heavy scrubbing that results in significant damage, we guarantee our cleaning method will not damage your roof.
