Much Ado About Moss

iko 5 (1)

Moss can be much more than just an eyesore, it can ultimately be a risk to your health and the integrity of your roof! Unfortunately the shingles that make up your roof, offer the perfect habitat for moss to grow and spread; your roof is usually humid and a little moist (especially if you live away from the coastline, and the shade often provided by surrounding trees, offer some protection from heavy sunlight. When you combine these factors with the accumulation of leaves and other dirt that comes naturally with roofing, it provides the nutrients required for moss to grow in abundance.

Moss retains a lot of water on the surface of your roof, much like a sponge, so over time, as the water freezes and thaws, the shingles crack and pull apart allowing leaks and rot to lay siege to your roof. Moss forms particularly quickly around the edges of shingles, pulling the edges apart and leaving your roof cracked.

Thankfully a little protection can go a long way, and moss can be combated with regular care. If you’d like us to come have a look at your roof you can get in touch through our contact page or check out our services page for more information on what we can do to fit your roofing needs!

What Causes Shingle Discolouration On Roofing

If you live in a humid area of the country, you’re probably used to seeing dark streaks on asphalt shingle roofing around your neighbourhood. This discolouration is often blamed on a combination of dirt, defective shingles, or even mold or mildew, but the most common culprit is actually a blue-green algae known as Gloeocapsa Magma that is spread by airborne spores.

Although this algae doesn’t door much real harm to roofing, it doesn’t always look good for the property and can affect the resale value of your home; especially if those viewing it attribute it to something more damaging like mold or mildew. Roofing contractors like ourselves will tell you that whilst algae like this can be removed, it is almost impossible to prevent, given that algae survives through feeding on limestone filler and photosynthesis.
