How to Clean Mold | Roof Cleaning – Preventing moss growth

How to Clean Mold – Spring and Summer bring about a desire to get some of those projects done around the home. Maybe you’ve noticed some staining on your shingles? Maybe there’s some moss growing up there that is looking a little wild? These are valid concerns for you and you should absolutely have it taken care of. Here’s what roof moss can do:

1.Increased wear and tear – Retains moisture, when frosts occur, the freeze can crack and fracture your shingles

2.Shorter roof life span – Weakens sealing on shingles. Shifts the shingles around and then can cause fragments

3.Leaking – Diverts the flow of water from its intended course and slows drainage. Can cause water to seep under the shingles

4.Mildew and Mold – Retains moisture, making it more prone to rot which can then spread into the attic below

5.More susceptible to bad weather – winds can further damage shingles and blow them off the roof

6.Lower home value – not only unsightly, but a damaged roof seriously diminishes the value of a home

So, knowing all those things, how should you treat the roof? How do you remove moss or mildew on the roof?

There are many ways that people say you can accomplish this. Some are better than others and each case can need something different.

In many instances, pressure washing may be too harsh a technique for performing the roof cleaning. This is because the high pressure water may cause damage to the shingles by ripping off the granules from the shingles. This can be done if care is taken, however an inexperienced or misinformed contractor may improperly wash the surface. This can put water under your shingles causing a water leak directly into your attic.

The generally accepted forms of cleaning typically involve a mixture of low pressure washing and some sort of chemical application. But before you reach for that bleach, you’d better stay your hand! Chlorine bleach can damage everything, wood lignin, plants around the house, etc. Just avoid it! Make sure any chemical being used on your property is biodegradable and safe!

So what exactly grows on your roof? Typically it is a mixture of moss, mildew, and lichen. This grows due to a natural amount of spores in the air, which are the “seeds” that grow forms of fungi. The growths concentrate on the north and northwest side of the home or roof due to minimal sunlight exposure which slows evaporation down which would otherwise remove moisture.

What preventative measure can be taken so you don’t have to spend a lot of time learning how to clean mold? Prevention can be lumped into two different types of methods. The first is by using copper strips in the ridge-line. As copper leaches out due to erosion, it inhibits the growth of any fungus below it as copper is a natural mold inhibitor. The other method is through a chemical application.

The Montana Mold Wranglers have a method which uses a non-toxic mold inhibitor that assists in preventing the moss, etc from growing on roofs.

We hope this helps you make some good decisions about how to go about this one particular project this year! Until next time…
