We used Demark's for a roof cleaning recently. We worked with Brandon who was great; professional, prompt, and sure-footed on my roof. Highly recommend their services based on the professionalism but also the affordable rate. Thanks, Brandon!

Is Your Roof Dirty?

Restore Your Roof to Greatness

If the beauty and glory of your home are gone because of your dirty roof, it is time to clean it. A dirty roof can bring life to a standstill and create an unforgettable eyesore in your neighborhood. Our climate creates the perfect place for particular algae to grow. This is why our DeMark’s cleaning professionals are the best at what they do. With our special cleaning process, your roof will see the greatness it deserves. 

The DeMark’s Difference

1. We use a low-pressure method that will not damage your asphalt shingles or void your roof’s warranty.

2. We use only environmentally safe and EPA-compliant cleaning agents (OSHA and environmental compliance).

3. We have developed a proven custom 100% biodegradable proprietary solution that includes special detergents to kill organic growth at the root.

4. We take every reasonable precaution to prevent damage to plants, shrubs, grass, and trees in surrounding areas. We will thoroughly wet all plants, including grass, shrubs, and trees. Remember the algae, mold, or lichen growing on your roof is a plant and must be killed at the root, or it can grow back in no time.

5. We post-treat your home, plants, shrubs, grass, and trees with a high-quality bleach-neutralizer and surfactant. Ideal for rinsing bleach-washed surfaces to prevent damage to sensitive siding and plants.

Restore & Protect Your Roof

Why Do I Need A Professional Roof Wash?

A clean roof not only adds to curb appeal but will last longer as a more efficient component of your home.

Your roof is your protection from the outside elements that float through the air. Throughout the year, it takes a beating from the different seasons and weather. Over time if your roof is not properly taken care of, the life of your roof could build up mold, dirt, and other invasive contaminants. 

Why is pressure washing my roof important?

  • Saves You Money – Cleaning your roof as regular maintenance can help it last longer against the elements, as well as save your wallet by avoiding premature repair and replacement. Roof washing is actually one of the lowest costing maintenance tasks with a large return on investment when it comes to curb appeal and saleability.
  • Increase Your Roof Life – The shingles and foundation will be saved on your home with a roof cleaning.
