    cyclone roofs

    Why are the roofs of 5th wheelers not made from a one piece fiberglass cap....like motorhomes? I see many threads with cyclone owners that have roof issues...with new model cyclones!!!

    Re: cyclone roofs

    I don't know for sure why the roof is not one piece fiberglass but I can think of a couple of possibilities.
    One could be the weight factor and another could be the way the coach is designed. A motor home frame has wheels on four corners (about). A fifth wheel has the wheels centered (about) on the frame. There could be some flexing and twisting that would not be friendly to a fiberglass roof.
    I dunno, just a couple of thoughts.
    As far as roof issues with new Cyclones I can't say that I have noticed any increase in threads indicating problematic roofs.

    Re: cyclone roofs

    Where are you seeing all of these "Cyclone" roof issues? I have heard of a couple that the roof membrane was billowing and a few with bubbles but they were not Cyclone specific issues. This is an issue across the entire spectrum of RV's with rubber roofs. All brands included.

    Re: cyclone roofs

    Fiberglass roofs work great on motor homes (rigid chassis with weight distributed over the outer 4 corners) how ever they do not work nearly as well in a 5th wheel. A fiberglass roof is very rigid and does not work well on 5th wheel because of the flexing in the chassis. The fiberglass roofs are also prone to cracking especially in severe weather conditions (many of our buyers are in the extreme cold weather of northern Alberta, or extreme heats of the desert). How ever we do appreciate the input, and always look forward to hearing product suggestions

    Re: cyclone roofs

    AJ,

    Has Heartland considered using TPO roofs? This material is thicker and less prone to punctures. I like to think of EPDM is like an inner tube, where TPO is like a tire. TPO is used by a few manufacturers, but is not very common. My guess is that it is more expensive.

    Thanks!

    I bought a 2011 Elk Ridge 29 ft a couple of months ago. Climbed up the ladder and the roof had multiple bubbles and a few large ridges. Took some pics and sent them to Heartland. Response from the rep was that this was "normal" and that he'd "seen it hundreds of times" and nothing to be concerned about. To me, it means poor technique when putting the membrane down, not applying sufficient adhesive and not working out the air pockets.
