Artists and poets depict moss-covered roofs as nostalgic and cozy, evoking the beauty and endurance of nature coexisting with human endeavor. Real life homeownership is significantly more prosaic though, because there’s nothing poetic about the damage that moss can do to that roof.
What Causes Moss on a Roof?
Moisture and shade are the primary reasons for moss on your roof. The problem is often exacerbated by clogged gutters or damp leafy debris on the roof – making conditions ripe for moss growth.
Is Moss Safe for Roofs?
Moss is detrimental to the health of your roof. It stains, holds moisture, prevents drainage, clogs gutters, and can peel up entire shingles. Not only can moss make your home look unkempt, but it can also shorten your roof’s lifespan.
Is Moss on a Flat Roof Bad?
Flat roofs aren’t immune to the destructive power of moss. Even without shingles, moss can trap moisture and damage your roof’s protective membrane. As with shingled roofs, moss overgrowth often clogs your gutters, leading to water ponding. Standing water can quickly weaken a flat roof, causing leakage and even roof collapse if left unaddressed over time.
How Do You Get Rid of Moss on Your Roof?
The best way to rid your roof of moss is to call a roofer with removal expertise. Many people attempt to address the problem themselves and end up doing more harm than good, causing significant damage to their roof, and costing themselves far more money than they would have spent on professional moss removal.
Soft washing is a gentle yet effective method for removing moss from a roof without causing damage. Instead of using high-pressure water, which can strip away roofing materials, soft washing relies on biodegradable cleaning solutions and low-pressure application to kill moss down to its roots.
Can You Pressure Wash a Roof to Remove Moss?
There’s a popular belief that pressure washing a mossy roof will solve the problem. Unfortunately, pressure washing often loosens shingles and forces water up underneath them. Additionally, while it may appear that the moss is gone after pressure washing, some spores usually remain and will take root… especially if conditions remain favorable for its growth.
