Sticky Situations: Pine Tar & Commercial Roofs

Maintaining the integrity of a commercial roof is important for the longevity and functionality of any building structure. Among the various threats that roofs face, pine tar and nearby pine trees pose a unique and often underestimated risk. While the natural beauty of pine trees may enhance the landscape, their proximity to roofs can lead to significant damage over time. Understanding the detrimental effects of pine tar and trees on commercial roofing systems can help property owners to take proactive measures to mitigate potential harm.

The Problem with Pine Tar:

Pine tar is a sticky, resinous substance that pine trees produce, primarily to seal wounds and protect against insects. While beneficial for the tree, when pine tar comes into contact with roofing materials, it can cause several issues:

• Degradation of Roofing Membranes: The sticky nature of pine tar can adhere to the surface of roofing membranes, compromising their integrity. Over time, this can lead to deterioration, weakening the roofing system and increasing the risk of leaks.

• Staining and Discoloration: Pine tar stains are notoriously difficult to remove from roofing materials. These unsightly stains can detract from the aesthetic appeal of the building and may require costly cleaning or replacement efforts.

• Increased Maintenance Requirements: Roofing systems contaminated with pine tar often require more frequent maintenance to prevent further damage. Regular cleaning and inspections are necessary to identify and address any issues promptly.

While pine trees may enhance the natural beauty of a property, their presence near buildings can pose risks to a commercial roofing system. By understanding the potential hazards and taking proactive steps to prevent damage, property owners can enjoy the added beauty and still preserve the integrity of their structures for years to come.
