Roof Moss & Algae Removal in Allerton
In Allerton, IL, the warm and humid climate can lead to a high incidence of roof moss and algae growth. With an average annual rainfall of 38 inches, moisture-laden air is often present on roofs, creating an ideal environment for these pesky organisms to thrive. This is especially true in homes with darker-colored shingles or those located in shaded areas, such as the numerous oak-lined streets that wind through Allerton's historic neighborhoods.
The median home value in Allerton is $106,700, but many of these homes were built back in 1965, when roofing materials and techniques were less sophisticated. As a result, older roofs are more prone to moss and algae growth, which can lead to costly repairs down the line. In fact, according to data from the City of Allerton's building department, nearly 60% of all homes in the city have roofs that date back to within the past 40 years – an age group where roof maintenance is particularly crucial.
Regular removal of moss and algae growth can help prevent premature roof failure and costly repairs. For homeowners in Allerton, our roof moss and algae removal service offers a cost-effective solution to address these issues. We use specialized equipment and techniques to safely remove unwanted growth, while also providing recommendations for prevention and protection – including the installation of zinc strips to deter future growth.

DIY vs. Call a Pro
