For the third instalment in our series of How to Prepare Your Vancouver Roof for the Winter, let’s talk about TPO roofs. How can you prepare your TPO roof for winter? Part 3: How to Prepare Your TPO Roof for Winter in Vancouver, BC Thermoplastic Olefin (TPO) roofing is a popular choice for flat or low-slope roofs because it is durable, energy-efficient, and resistant to the elements. However, like all roofing systems, TPO roofing requires specific maintenance to ensure it withstands Vancouver’s winter conditions. Here are some tips to help you get your Vancouver TPO roof ready for winter: Conduct a Thorough Inspection Start with a thorough inspection of your roof. Look for: Inspect for Tears, Cracks, and Seams – TPO roofs are known for their durability, but the seams can wear over time, especially under heavy rainfall or freezing conditions. Inspect the entire surface of the roof and TPO membrane for any tears, cracks, or holes. Pay close attention to the seams and edges, as these are where leaks are most likely to develop. Use a TPO-compatible roofing adhesive to patch any small cracks, or consult a professional for more extensive repairs. Check the Drains and Gutters – TPO roofs are typically equipped with drains to help manage water runoff. Check that all drains, scuppers, and downspouts are clear of blockages. Standing water on a flat roof can lead to leaks and pooling, which can worsen during freezing temperatures. If you notice that the drains are clogged or damaged, you should make repairs or clean them out to ensure proper water flow. Ensure Proper Drainage – Vancouver is known for its heavy rainfall, and inadequate drainage can lead to significant issues on a TPO roof. Ensure that your roof is sloped correctly and that there are no areas where water could pool. If necessary, consider installing additional drainage systems or modifying the slope of the roof to allow for better runoff. Keep Your Roof Clean and Watertight Clean the Roof Surface – Debris, such as leaves, dirt, and branches, can accumulate on a TPO roof and cause drainage issues. Since TPO roofs are flat or low-slope, it’s important to ensure that water can flow off the surface. Make sure you clear away debris, and use a gentle cleaning solution to wash the roof. Avoid using harsh chemicals that could degrade the TPO membrane. Make sure the roof surface is free of oils, dirt, and mold that could affect its performance in wet conditions. Inspect and Reseal Roof Penetrations – Penetrations from HVAC systems, vents, and pipes can be vulnerable areas on a TPO roof. Check these areas for any signs of wear or gaps in the seals. Reseal around these penetrations using a TPO-compatible sealant. Ensuring these areas are watertight will help prevent leaks during the rainy and snowy months. Plan Ahead Trim Overhanging Branches – Branches that hang over your roof can pose a risk during winter storms. Trim any branches that could fall or scrape against your roof, preventing potential damage and reducing debris accumulation. Schedule Professional Maintenance – Prevention is key to avoiding costly repairs down the line.
