Why does my roof look so dirty?

First, concern about a "dirty roof" isn't just about aesthetics.

Odds are that "dirt" on your roof isn't all "dirt."

Some of that "dirt" is probably alive.

Often, black or very dark stains on a roof are caused by a type of blue-green algae.

That's bad enough. However, that algae retains water as it grows, which promotes the development and growth of other roof contaminants such as fungi.

The algae spores feed on the limestone in asphalt shingles and the actual dirt on tile roofs.

So those black or dark stains on your roof are probably home to a number of molds and fungi in addition to algae.

Fungi are normally found on the north-facing slopes of roofs, especially ashphalt shingle roofs, because these are the coolest and dampest surfaces for the longest periods of time during a day.

Roofing tar is a major component of asphalt shingles as well as most types of flat roofing material. Roofing tar is made from crude oil. Crude oil is fossilized organic matter, which is a good food source for fungi (as is the algae). And that's one reason fungi love asphalt-based roofing systems.

Why Keep Your Roof Clean?

Not all mold (fungi) and algae present health dangers to everyone. The elderly, children, and those suffering from asthma and allergies are most vulnerable.

Some enzymes are a by-product of fungi digestion. These enzymes convert some other compounds into more food for the fungi. These digested nutrients also produce compounds known as mycotoxins. Mycotoxins can also be toxic to people producing symptoms like cold or flu, sore throats, headaches, nose bleeds, fatigue, diarrhea, dermatitis, and immune suppression. In addition, some mycotoxins may also be carcinogenic. While specific conditions must exist for these mycotoxins to be produced, it is unknown exactly what those conditions are at this time. The potential risk is there, nonetheless. The old saying, "An ounce of prevention is worth a pound of cure," is certainly the safer approach.

Spores on the roof can be carried inside the structure by several means:

  • Wind (through windows, doors, and depositing spores on the ground)
  • Foot traffic tracking spores in from the ground
  • Air conditioning and heating intake air vents (which contaminates the vents so they must also be cleaned)

Therefore, mold growth is not something to be taken lightly. Mold growth should be dealt with quickly and professionally.

Roofing asphalt is consumed from the top down. As the top material is consumed, the protective granules loosen and fall off the roof, exposing even more of the roofing asphalt to fungi and UV attack from the sun (which causes cracking).

In general, the cleaner the roof, the longer it will last.

America's Best has been in pressure washing residential and commercial properties for nearly 3 decades.
Pressure washing can enahnce the value of your property while keeping it attractive and healthy.
Power washing is often used as a highly effective, relatively low cost way to deal with many problems, including graffiti, paint and oil spills, or stains.

How often should roof be cleand?

It depends.

If your roof is in an area that gets very little rain, is far from tall trees, and is not near the ocean, then roof washing every year or two would probably be sufficient.

If your roof is near tall trees, or in an area that frequently has heavy dew (such as near the ocean or large body of water), or has valleys that trap and collect debris, then roof washing every year is probably necessary.

Debris on roofs from trees (pine needles, leaves, branches, seeds, sap), birds, animals, combined with any moisture provides an excellent breeding ground for algae and fungi.

If your roof looks dirty, it is probably worse than it appears and roof cleaning should be done as soon as possible.

No roofing material is immune to algae and fungi growth. These contaminants can grow on asphalt shingles, tile, slate, asphalt and synthetic roofing, as well as metal roofing materials.

Can I clean my roof myself?

Yes you can. Here is a partial list of what you will need to attempt your own rain roof cleaning:

  • Ladder that will reach your roof
  • No fear of heights
  • Wire brush, putty knife
  • Pressure washer (rent or buy)
  • Safety glasses
  • A safety harness securely anchored to the building to make sure you can't fall off (or through) the roof (OSHA considers a fall of 2 stories, or more, to be a "death fall").
  • Valid medical insurance (in case you fall, get debris in your eyes, or cut yourself)
  • An able-bodied assistant (never try to do your own roof cleaning without an assistant for safety)

How to Choose a Roof Cleaning Service Provider?

  • Get at least 3 roof cleaning quotes.
  • Have each contractor quote both one-time and routine service. Never pay a contractor for an estimate.
  • Carefully check their liability, worker’s compensation, and vehicle liability insurance coverage. Make sure they list you as “additionally insured” on their policies.
  • Make them state, in the contract, that all members of their crew who will be on your property are employees of the contractor and the contractor will not use “day labor.”
  • As a general rule of thumb, if the difference between the highest and lowest bidders is more than 10-15%, be extra careful to confirm all 3 vendors are bidding exactly the same thing.Ask for roof cleaning references, and check them out carefully.
