Your roof is your home's first line of defence against the elements. However, natural growths like moss and lichen can take hold over time, leading to serious damage if left untreated.
While these organisms may seem harmless, their presence can weaken your roof's structural integrity, cause costly water damage, and lead to other long-term issues.
In Hamilton and across the Waikato, the humid climate creates the perfect environment for moss and lichen to thrive. These growths not only make your roof look unsightly but also shorten its lifespan by trapping moisture, loosening tiles or shingles, and even causing leaks.
Understanding the risks associated with moss and lichen growth is essential for homeowners who want to maintain a safe and durable roof. Below, we explore how these organisms damage your roof and why a professional roof moss treatment from Dry Gutts is the best solution.
How Moss and Lichen Damage Your Roof
Moisture Retention and Water Damage
For instance, moss acts like a sponge, absorbing and retaining large amounts of moisture from rain, fog, and dew. This persistent dampness creates the ideal conditions for roofing materials to deteriorate, particularly asphalt shingles or concrete tiles.
The longer moss remains on a roof, the more water it traps, which increases the risk of rot and mould growth beneath the roofing surface.
Water retained by moss can then seep into small cracks and crevices in shingles and tiles. Over time, this infiltration leads to leaks that can spread into the underlying roof structure, causing damage to insulation, ceilings, and even interior walls.
Additionally, persistent moisture creates a breeding ground for fungi and mould, further weakening your home's structural integrity. Regular roof moss treatments from Dry Gutts can prevent moisture-related damage and keep your roof dry and secure.
Tile and Shingle Damage
As moss and lichen spread their way across a roof, their root-like structures cling to roofing materials, creating cracks and gaps between the tiles and shingles. This loosening effect weakens the adhesion of roofing materials, making them much more vulnerable to strong winds, heavy rain, and storms.
In some cases, this moss growth can expand to the point where it even causes tiles to lift completely, increasing the risk of water infiltration and unwanted leaks.
Lichen, in particular, secretes acidic compounds that slowly break down roofing materials. Over time, this corrosion weakens the protective layers of asphalt shingles and concrete tiles, reducing their effectiveness in repelling water.
If left untreated, the cumulative damage caused by the moss and lichen can lead to unwanted expensive roof repairs or even premature roof replacement.
Blocked Gutters and Drainage Issues
When moss and lichen break away from a roof, they often will fall into the gutters, creating blockages that end up preventing proper water drainage.
When the gutters become clogged, rainwater has nowhere to go and can begin to overflow. This overflow can then cause damage to the walls, foundations, and landscaping around your home.
Excess moisture buildup in blocked gutters can also lead to the growth of algae, mould, and mildew. Over time, standing water in gutters can even cause rust and corrosion, weakening the gutter system and leading to costly replacements.
Keeping your gutters clear and having professional roof treatments from Dry Gutts can prevent these issues before they escalate.
Increased Weight and Roof Stress
A thick layer of moss may seem harmless, but when it's wet, just like a bath towel, it becomes significantly heavier. This additional weight then puts unnecessary stress on the roofing structure, which can be particularly problematic for older homes with weaker supports.
If moss growth is ignored, the constant added weight can contribute to sagging areas in the roof, which in turn, potentially lead to structural failure. Excess weight also increases the risk of tiles cracking under pressure, opening up more pathways for water to infiltrate and cause hidden damage.
By scheduling a regular moss removal treatment with Dry Gutts, you can prevent unnecessary stress on your roof and extend its lifespan.
Algae Growth and Roof Staining
Lichen is often accompanied by algae, which tends to leave dark streaks and stains on roofing materials. These stains may not seem like a significant issue at first, but they indicate to us, an ongoing deterioration.
Algae and lichen both break down the protective outer layers of asphalt shingles, tiles, and metal roofing over time, leading to increased wear and tear.
Beyond the structural risks, roof staining negatively impacts your home's curb appeal and resale value. A roof covered in dark streaks or discoloured patches can make your home look poorly maintained, which can be a problem if you plan to sell in the future.
Regular roof treatments from Dry Gutts not only prevent this type of staining but also restore the clean and well-maintained appearance of your home's exterior.
