    IB Roofing (pvc) vs. CertianTeed Roofing
    Can anyone tell me the pros and cons between these two roofing materials. I am in charge of having a roof replaced for our city council. We have had several contractors come in and give us estimates and its down between these two. Both are at the same cost. This is going on a building with a flat roof where water is know to stand in several places of the roof.

    My husband has been roofing for six years and out 20 or so roofs when the choice was either PVC of other always go with other PVC dosen't stand the length in time and we suggest building a frame over the flat roof because flat will always have problems weather the roofing company is 5years old or 50 years old soggy is soggy no matter what it will also increase the value of the property so in the futrue if you relocate the City council you could have a edge on the market. Also if you do go with build over at any pitch use a metal roof and have vents installed so the bulding can stay breathable.

    Certian-Teed makes a variety of roofing. If you are looking at a single ply rubber material, likely either it or the vinyl will last a very long time. Much of the job depends on the workmanship where the roofing seams and protrusions are sealed. Any good single ply roof should last at least 20 if not 50 years. I have done some investigation on this and just authorized having a vinyl roof installed on the flat portion of my church's roof.

    I don't know large your building is, but on a very large one, a roof, sloped enough to drain well, becomes very high. I once managed a factory with a metal roof with a gentle slope. It was a huge pain with expansion and contraction opening new leaks every season change. All winter we had to leave empty spots in the warehouse under where it leaked around the heating vents.

    I would ask for names of customers each worked for 5 years ago. If ones bad workmanship lead to leaks, go with the other.

    As for a flat roof I've always use a rubber membrane and a fiber board underlayment.
