Unlike homes, commercial buildings are designed with flat roofs. While this offers certain advantages, it can make your roof more prone to water damage and leaks. If your current roofing system is old or worn, it may be time for an upgrade from a reputable roofing company in Vaughan. New roofing materials, when paired with waterproofing in Vaughan, can go a long way in improving the durability and longevity of your roof. If you notice structural concerns with your roof or consistent leaks, contact the experts at King Koating for repairs.
Here are some common signs your roof needs waterproofing.
Persistent Roof Leaks or Interior Water Stains

If you’ve been struggling with constant roof leaks, this indicates that your roofing materials have deteriorated. Over time, when exposed to water, roofing materials can weaken at the seams, creating gaps that allow water into your building. These leaks can cause yellow staining on the inner walls of the ceilings of your property. Not only is this an aesthetic issue, but it can also deteriorate drywall, which will need to be repaired.
Waterproofing can seal vulnerable areas of your roof and prevent water from spreading deeper into the structure.
Pooling Water After Rainfall
If water is pooling on the surface of your roof for more than a day or two after rainfall, this is a major sign that you require roof repair and waterproofing in Vaughan. Pooling water indicates an issue with your roof drainage system and when left untreated, standing water can accelerate roof deterioration, further increasing the risk of leaks. Addressing the drainage problem will help prevent pooling. When paired with waterproofing, you can feel confident that the inside of your property will remain dry even after heavy rainfall.
Cracks, Blisters, or Membrane Damage
Visible cracks, blisters or general damage to the surface of your roof indicates that the protective layer has weakened. Once again, these openings allow water to enter your building, resulting in mold, structural damage and staining. Applying a waterproof coating on top of these vulnerable areas can extend the lifespan of your roof while sealing off any of these openings.
Aging Roofing Materials
Most roof materials have only a limited lifespan. As materials age, they become more susceptible to water penetration and weather damage. If your property or roofing is old, consider a roof inspection or adding waterproofing to extend its lifespan and prevent any further deterioration.
Rising Energy Costs
Rising energy costs is a less obvious indicator that you may want to upgrade your roof with waterproofing. As water infiltrates your building from the roof, your insulation will deteriorate and loose its effectiveness, leading to rising energy costs.
