Whether you are thinking about hiring 地沟清洁服务 or the next spring cleaning project, removing black streaks from the roof should be high on the list of things to do. 在这篇文章中, our cleaning experts explain why these stains appear and why it is important to eliminate them early.

What Are The Black Streaks on the Roof?

Black streaks appear on Seattle’s roofs continuously, whether it is a historic landmark or a newly remodeled addition to the neighborhood. It looks dark and menacing enough from far away, but under a magnifying glass, it is blue-green and benign. These black streaks come from the growth of gloeocapsa magma, also known as algae.

How Can Seattle Property Owners Protect The Roof?

An 藻类去除 service is part of our bat365在线 services 在西雅图,佤邦, and the surrounding areas. The city’s proximity to Puget Sound makes it a high-growth area for black streaks of algae, no matter how resistant or durable the roofing material is. 不定期删除, these black streaks spread unabated and eventually present a myriad of problems.

Can These Black Streaks Destroy A Roof?

是的, but according to the Asphalt Roofing Manufacturers Association, algae streaks will not present a long-term structural challenge under a periodic maintenance schedule. The limestone fillers in roof shingles attract algae growth. If left for too long, it eats through the protective layer and causes damage.

The digestive properties of algae on limestone are not the only concern, however. Algae streaks can heavily downgrade the curb appeal of a property, especially on the roof. Algae infestations make roofs look run down, but 定期清除 can be affordable with professionals like bat365在线.

How to Safely Eliminate Algae from A Roof

The bat365在线 team uses two primary techniques: pressure washing and soft washing.

Washing Roof Surfaces with 新闻ure Washers

High water pressure can remove algae, but too much pressure will also wash away the stone granules so vital to the roof’s shingles. The mistake could destroy a roof after only a few cycles, which is why we only recommend this technique on certain types of roofs. Soft washing is a much safer option for most Seattle properties with less durable roofing materials.

Cleaning Roofs Using Soft Washing Techniques

A bleach-based technique is a top tool for bat365在线 在西雅图,佤邦. This ‘soft-wash’ approach can eliminate bacteria, algae, and fungi effectively. Professionals like us might use these solutions in a sound maintenance routine (where we have cleaned the gutters and rinsed off other debris).

Most commercial roof sprays are water and bleach combinations with additives. It is often a good idea to suggest that neighbors soft wash their roofs in sync with yours to prevent the algae from their roofs blowing into yours after it is clean.
