Signs it’s Time to Replace Your Commercial Flat Roof

Recognizing the signs that would require replacing your commercial roof is the first step. There are often indicators that your flat roof is experiencing issues, these range from:

Consistent Leaks
Water Pooling
Damage to Roof Membranes
Cracking or Blistering

Typically, these indicate there is some form of issue that will need to be addressed and whether that requires a full roof replacement or can be fixed by a repair can only be determined by a commercial roofing professional.

Roof Materials

Why Roofing Materials Matter

Not only does ensuring the proper material is used on your roof sustain the life of your roof, it makes the difference on how well the roof withstands St. Louis’ harsh elements. Frederic’s commercial team specializes in single-ply membranes which include a variety of options such as TPO (Thermoplastic Olefin), PVC (Polyvinyl Chloride), and EPDM (Ethylene Propylene Diene Monomer).

The benefit of using these materials ranges, as they are overall represent easier installs, which can save you money on your commercial property, they are UV resistant and are also chemical resistant as well.
