The roof is exposed to the weather elements throughout the year and seasons. Over time, debris and contaminants are going to accumulate. This not only negatively impacts appearances but also causes damage that can lead to costly repairs. This is why it’s important for Kirkland homeowners to regularly hire rooftop cleaning services. Here’s a look at the three most common rooftop contaminants.
Moss and Algae
Moss and algae may appear seemingly harmless, but they can cause extensive damage. These elements contain moisture, and when they collect under the roof tiles, the moisture can lead to mold growth. This contaminant is especially commonplace in regions with humid environments.
Lichen
Lichen is a symbiotic organism that manifests in the form of fungi. Like moss and algae, lichen can collect on the roof surface, mainly in sections that receive a lot of shade. Lichen can be more hazardous to the roof than moss because its roots can penetrate and latch onto the roof tiles and membrane. Apart from causing physical damage, this also makes them more difficult to remove. Removal may require commercial pressure washing.
Mold and Mildew
Mold and mildew are fungal parasites that thrive in high-humidity environments. They are not only an eyesore but can also lead to health problems, especially if this is accompanied by a roof leak, where the mold can spread into the interior.
