Moss and Algae… threats to your roof.

Do you see a green tint on your roof… something might be growing on your roof – moss or algae.

Moss and algae and the effects they could possibly have on your roof should be closely examined. Some of the most apparently harmless, yet unsafe things that could be on your roof right now include moss, algae, and rubbish such as leaves. Moss and leaves can snare moisture beneath them, which means that roof holding them will stay moist for extensive periods of time. This wetness will ultimately begin to break down into your roof, causing it to weaken at a much faster rate. In time, this moistness will begin to leak into your roof causing rot, mildew, or mold in your ceilings and other parts of your home.

Moss

In places with humid and rainy climate conditions moss begins to develop on the roofs. Most people tend to ignore moss as just an visual problem that reduces the pretty front of our homes. While moss itself doesn’t not harm the roof materials, if left alone, moss will begin to provide an situation that holds in dampness. When the moisture is held in a focused area of the roof surface over a extended period, damages requiring costly repairs can result. Moss growing on any roof surface will be more severe on roof sectors that are sheltered and unprotected to periodically moist and cool weather situations.

Algae

Just like moss, algae is drawn to warm, damp spaces. Though it is not as damaging as moss, it can still lead to a number of difficulties and can bring down your home’s look and worth if you don’t take steps to remove and avoid its return. The existence or nonexistence of much light on a roof surface is often a decisive factor in the amount.

Prevention

Recurring application of a chemical treatment can often efficiently stop the return of moss and algae, but there are other eco-friendly choices to ponder:

  • Provide the roof surface added sunlight. Trim back trees whose branches dominate the roof surface. Keep the roof dirt-free of organic rubbish like leaves which may gather in valleys or at other roof places.
  • Clean your roof with water. We use specialized gear to deliver high-pressure water discharges to remove additional dirt, muck, moss, algae and other pollutants on your roof.
  • If re-roofing is needed, make sure to fix roofing that has anti-algae and anti-moss types whether in the materials used or in its coating.

Cleaning, treatment and maintenance should only be done on roofs that are not too vertical to be carefully walked on, or only if you’re a professional with the right equipment.
