With the many different combination of thicknesses or membrane color, it is important to know the expectation on how it is wished for the roof system to perform. Like EPDM, there is great warranty protection for commercial properties depending on the product choices.



Like any other roof, flat roofs need the water to go somewhere.  Depending on the design of the roof, the water may shed or directed to drainage points.  A certain amount of ponding is acceptable, but it is always best to have a minimum standing water for any extended period of time.  TPO will show any low points on the roof system.



Any mechanical, electrical, and plumbing vents coming through the roof membrane must sealed properly.  These are usually the first areas to fail whether from age or poor roofing practices. Chateau Roofing & Siding uses the newest innovative methods when ensuring the integrity of the whole roof system is done properly where the roof system is most vulnerable.  TPO has very specific requirements when performing the details.  It is important that you have qualified installers to avoid future issues.



It is unlikely any issue will arise after the roof has been completed.  At Chateau Roofing & Siding, we will provide a workmanship warranty on new roof systems that will protect you from any errors in the application of the roofing system.  After this period of time, a regular inspection is highly recommended to insure that the roof is remaining functional and any issues are not arising for whatever reason.  Please ask about what kind of program will suit your needs.
