Adhesive Applications

While heat welding is ideal, adhesives can be used for seam repairs in certain situations, particularly for small repairs or areas difficult to access with a heat gun.

• Use compatible adhesives: It’s imperative to use adhesives specifically designed for TPO membranes to ensure proper adhesion and long-term performance.

• Proper surface preparation: Clean and prime the surfaces before applying the adhesive.

• Follow manufacturer’s instructions: Adhere to the recommended application techniques and curing times for optimal results.

Puncture Repair: Sealing Membrane Breaches

Punctures, often caused by debris, tools dropped during maintenance, or even animal activity, are another common source of leaks in TPO roofs. Addressing punctures promptly is critical to prevent water infiltration and further damage.

Common Causes of Punctures

• Debris: Sharp objects like nails, screws, or broken glass can easily puncture the TPO membrane.

• Foot Traffic: Heavy or careless foot traffic can also contribute to punctures, especially if the membrane is already weakened.

• Storm Damage: Hail or wind-blown debris can create punctures or tears in the roof.

Using a Membrane Patch

The most effective method for repairing punctures in a TPO roof is to use a membrane patch. This involves cutting a patch of TPO membrane slightly larger than the puncture and welding or adhering it over the damaged area.

• Cleaning and preparation: Thoroughly clean the area around the puncture and the underside of the patch.

• Patch placement: Position the patch over the puncture, ensuring it completely covers the damaged area.

• Welding or adhesive application: Use a heat gun or TPO-compatible adhesive to secure the patch to the existing membrane. Pay close attention to the edges to ensure a watertight seal.

Compromised seams and insidious leaks are challenges every property owner with a TPO roof will eventually face. But how does one transition from identifying these problems to actually fixing them? The answer lies in a structured approach, combining careful assessment with the right tools and knowledge.
