Why clean it all?

Why clean it all?

Often customers ask us to clean only the portion of their property that shows the most amount of mold, mildew, and other environmental debris. Typically, in New England that means the northern-facing areas of residential and commercial structures. This is because these areas receive less sunlight in the Northern Hemisphere (it’s the other way around in the Southern Hemisphere). Sunlight aids in drying out the southern-facing areas of structures much more quickly after rain, and since the growth of algae, mold, and mildew is accelerated by moisture, you can see how sunlight plays a role.

However, it is important to understand that even though the sun helps to slow the growth of algae on southern-facing surfaces, it does not stop it. If stains are beginning to develop on northern-facing surfaces of your roof surface, it means that it’s just a matter of time before the entire roof is covered with algae stains. Although black algae stains may not be visible on the southern-facing portions of the roof surface, that doesn’t mean that algae hasn’t already taken root and begun to multiple in these areas.

That’s why even though it may appear that stains are confined to one side of structure or roof it’s a good idea to have all surface areas cleaned. Remember, if algae can be seen on one part of the roof, that means its everywhere on the roof. Of course, requests can be made that only a portion of the property be cleaned, but often within a year that area will still be clean while the rest of the structure is suddenly covered in now visible mold, mildew, and algae.
