If you own a commercial building, chances are, you have a flat roof. Despite what their name implies, flat roofs are not completely flat; they simply have a very small slope to them that is usually not visible to the human eye. Due to their reduced slope, the type of roofing materials used on flat roofs varies from the types of roofing materials used on sloped residential roofs. PVC membranes are some of the common materials that can be used on a flat roof. If you have a flat roof that is aging, you may be wondering what the signs are that the roof needs to be replaced. Here are three of those signs.
There Are Visible Tears or Rips in the Membrane
One of the tell-tale signs that your PVC membrane needs to be repaired is that the membrane has visible rips, tears, or holes in it. Membranes that rip, tear, or have holes cannot be repaired. In some cases, a roofer may be able to layer a new sheet of PVC membrane over an existing tear or rip to solve the issue. However, if there are multiple points of damage on your flat roof, replacing the membrane is the better option.
The Membrane Has Significantly Faded
Another key sign that indicates that your PVC membrane roof needs to be replaced is a membrane that has significantly faded. PVC membranes hold their color fairly well, helping your flat roof to look its best for years. However, as the membrane ages, it can start to fade, making the membrane look old and worn. This is a sign that your membrane is starting to break down and replacement is needed.
Water is Not Draining From the Roof
The final sign that signals that your PVC membrane roof needs to be replaced is water not draining from the roof. If you see water pooling on the membrane, it likely means that the membrane is starting to wrinkle. These wrinkles in the membrane prevent water from sliding off the roof and draining away as it should. If you do not replace the membrane, the water may weaken the membrane as it sits in place, and eventually cause a leaky roof.
PVC membranes are commonly used as a roofing material on flat roofs. The membrane is fairly inexpensive and easy to install. However, once the membrane reaches the end of its lifespan, it needs to be replaced to help ensure that your roof can protect your building from the elements. If your PVC membrane is displaying one or more of these signs, the membrane on your flat roof should be replaced. Reach out to your preferred roofing contractor to schedule an appointment.
