Modified bitumen roofs are one of the most common types of commercial roofs. This is because this material is relatively affordable and easy to install on flat or low-sloped commercial roofs. However, modified bitumen roofs are not long-lasting, and as such, you should always be on the lookout for signs that may indicate that it is time to replace your roof. Here are a few of the key signs that it may be time to hire commercial roofers to replace your modified bitumen commercial roof.
Your Modified Bitumen Roof is Wrinkling
One of the signs that it may be time to hire commercial roofers to replace your modified bitumen roof is a modified bitumen roof that is starting to get wrinkly or one that is starting to lift along the edges. If the modified bitumen is starting to lift along the edges or get wrinkly, it is no longer properly adhered into place. As such, it may not be offering your roof the level of protection it needs. Wrinkles can also be indicative of water trapped beneath the membrane, which can possibly lead to leaking.
Your Modified Bitumen Roof is Starting to Peel
Another sign that it is time to call in commercial roofers for possible modified bitumen commercial roof replacement is a roof that is starting to peel. If your modified bitumen roof is starting to peel, it is undergoing a process known as delamination. Delamination occurs as your modified bitumen roofing material starts to break down due to sun exposure, weather element exposure, and exposure to both hot and cold temperatures. Replacing the modified bitumen is recommended once peeling is present.
Water is Sitting on Your Modified Bitumen Roof
The last sign that commercial roof replacement may be needed for your modified bitumen roof is water that is sitting on the roof instead of draining from the roof. If water is sitting on the roof, or puddling or pooling, it can lead to roof leaks. Minor dips or indents are often the cause of water sitting on a commercial roof, and replacing the roofing material may be needed to help water drain as it should.
If you notice that your modified bitumen roof is starting to get wrinkly or lift from the edges, is starting to peel or water is not draining from the roof, your roof may be near or at the end of its lifespan.
