So here I am on the roof of our 2013 TT. That's because during a recent driving rain we got water on the carpet below a vent. Yep, two years old and the vent covers look like they are at least 10 years old and a small crack has appeared in the plastic near the crank metal support. All three vents covers getting replaced, as they all look and feel like you could stick a finger through them in about any spot.
But it was while on the roof checking this out that I ALSO see the factory applied lap sealant looking like it's getting old too. Natural expansion cracks appearing but enough questionable areas that I'm thinking I'll replace it all as well.
So here's the question. Would you clean it off and re-apply lap sealant or would you go further and apply Eternabond tape as a replacement for the lap sealant method?
Roofs need to be checked yearly....we are resealing the roof on our 2 year old Class very soon ourselves. As for the Dicor stuff there are two different products. It depends on the roof type you have. Check the dicor page and they have a video telling you which roof you have. I contacted Thor Motorhomes and they told me what kind we have (TPO). Dicor has an Ultra Sealant that you need to use a primer with for TPO roofing. Dicor also told us we not need more than 6 tubes to reseal our roof. For the cap and sides, we will probably go with something like Proflex.
