Performance & Appearance

Bio-contaminants such as bacteria, moss, mold, lichen, and algae can diminish the performance
and tarnish the appearance of your commercial roof.

Performance

Single-ply roofs are designed to be highly reflective, which is both energy and cost-efficient. The above-mentioned biological contaminants cause surface staining that severely diminishes your roof’s reflective capacity, which generally results in lower energy efficiency and a net higher energy bill.

A clean roof is much more efficient at reflecting the sun’s rays, which results in a lower surface temperature of the membrane. A clean TPO or PVC roof membrane produces an immediate reduction in interior reflective heating. A “Cool Roof”, helps maintain a cool building and results in energy saving for cooling costs.

Our single-ply roof cleaning methods restore your roof’s reflective capacity to like-new condition and allow your roof to function at optimum design efficiency.

Appearance

The same contaminants that reduce your roof’s performance also make it look very unsightly. With so many local and even international airports around the Bay Area, many companies are concerned about the thousands of people who are viewing their facilities from above – daily – and how their roof’s appearance may reflect on their business and brand.

Safe Wash

Our approach adheres to the guidelines outlined by the CFFA (Chemical Fabrics & Film Association – the leading experts on polymer-based manufacturing). We have made a concerted effort to fine-tune our techniques over the years to ensure that you get maximum results with NO damage to your commercial membrane roof.

We do not use high pressure or other aggressive products or techniques that are specifically prohibited by manufacturers.

Trusted and Certified

Experienced Professionals

Perhaps more important than our professional affiliations are the decades of real-world knowledge and experience in roof installation and maintenance. As an NRCIA certified roof inspector and building contractor, we have both professionally installed and inspected all the materials we now clean and restore.

In 2010, we pioneered safe, non-pressure roof cleaning in Northern California. We are published experts and educators in the field of safe roof cleaning and restoration. We are uniquely qualified to clean and maintain your single-ply roof.

Commercial membrane roofs generally represent a significant investment for any business. At Pacific Exterior, we are aware of the proper cleaning procedures and products that are best for your PVC or TPO membrane roof. This includes the application of safe cleaning solutions that break down mold, dirt, and algae but do not compromise the integrity of the membrane.

We never use equipment, techniques, or chemicals that are explicitly prohibited by the manufacturers or bad for the environment. We are committed to protecting your investment.

Frequently Asked Questions

It is easy to see on most homes while the growth is in process; there are dark black streaks, particularly on the north facing roof, though once the algae has fully taken over it is sometimes hard to tell. (It's never too late to remove.) The best place to look to find out if your roof is dirty is below metal roof jacks flashing and sky lights. There you should find lighter colored streaks or patches...that is the original color and that is what your roof will look like after we have completed our service!

Yes. Pressure washing will dislodge the granules from the surface of the shingles and can scar the shingles causing more problems than you started with. Shingle manufacturers make it very clear that no pressure should be used to clean roofs. Although leaving the roof apparently clean looking, pressure washing alone does not kill the algae and the problem quickly returns. Tile roofs are also susceptible to damage from pressure, particularly the glaze finish and color pigment. The typical result is that the tile loses its color and is left far more porous. The new porous surface fosters the regrowth of algae, lichen, and moss. Removing the outer surface of roof tile using pressure also allows moisture to enter the tile which accelerates degradation.

As soon as you notice any signs of the shading or staining. The gloeocapsa magma bacteria is relatively easy to remove. Moss and lichen require much more time and effort. Even after the treatment, a small amount of dead moss will remain, left to decompose over time. The best time to treat a dirty roof is before signs of moss or lichen.

Yes. Cleaning your roof can save you money in more ways than one...

  • First, the algae and fungus that grow can cause premature roof granule loss, and shorten roof shingle life. So you save money because your roof lasts longer
  • Second, when the algae turn your roof black, it becomes less reflective, and it retains heat; If you use an air conditioner it has to work harder to overcome the increased heat load, costing money in electric bills.
  • Third, the aesthetics of cleaning your roof when it comes to selling your home can not only save you money but can make you money too.
