Wood Roofing: Preventing Fungal Attack

We need safety, we need belongingness – we need a shelter, a home. And home is often found in a house. A house is sometimes referred as “roof”. In this, we know how significant the roof is not only physically but also figuratively. Choosing the right roof and maintaining its condition is a must to show how we value our home.

I believe that having wood roofing will give us the best homey feeling more than any other roofing could give. I would even argue that at least once in our life, we wished to be sheltered by it. And so, for those who have it and for those who want to have it, know the best ways to maintain it.

Wood shingles and shakes are best for areas with strong winds and hail. However, among other kinds of roofing, there are drawbacks that require attention and care. Although it is designed for a longer life span for about 40 years to 60 years, lack of maintenance can decrease its life span down to just 10 year.

Wood Roofing

Cracked, warped, and missing wood shingles, which are sometimes caused by improper roof instalment, are common damages that require immediate repairs. However, the most serious problem we can ever encounter in having wood shingles are the fungal attack. This requires more than repair, it requires regular checking and maintenance.

The more you ignore it, the more it will aggravate. Some fungi ruin the color of the wood, some also attacks the properties of wood, which makes it durable, making the wood degrade into disfigured surfaces. So here are the tips on how to deal with this fungal attack to avoid early roof replacement.

1. Clean and Clear Up

  • Clear off debris such as leaf litters
  • Clear off mosses and lichens
  • Clear off overhanging vegetation that shades the roof
  • Clean the roof using cleaning solutions, scrubbing, or even high-pressure washers (be careful in using to prevent erosion of shingles)

The main purpose of this first step is to prevent water or moisture forming or accumulating on the shingles and in between them. Mosses and lichens accumulate soil and other debris in the roof which stores water for a longer of time encouraging fungal growth.

Also, the overhanging vegetation such as tree branches shades the roof which helps retain moisture. Cleaning the roof and clearing off the debris, mosses, and lichens should not be missed before wet seasons begin.

2. Preventive Treatments

  • Wood Preservatives
  • UV Protection
  • DO NOT Stain or Varnish the wood shingles

Wood preservatives are chemical solutions that impedes or delay the growth of moss, lichens, or fungi and are effective on extending your wood roof life span. Some examples are copper naphthenate, zinc naphthenate, MTC and TCMTB, copper and quinolinolate, TBTO, etc. Also ultraviolet rays break down cell wall materials of the wood surfaces degrading the quality of the shingles. Do not stain, varnish, or seal the shingles because the wood requires breathing.

3. Slope

Before even building or designing the roof, the slope of the roof actually significantly increase the life span of the wood shingles. This is because, the more sloped the roof, the less water it’ll accumulate whenever it rains.
