Next time you’re on the roof check it out and fill them if you have them. 2019 model
We bought a unit built in 2017, new, as a 2018 model in July of 2019. I assumed correctly that nobody had done any maintenance on the roof, so before winter, I went up and cleaned, as per spec, with mineral spirits and then resealed everything with Dicor lap sealant—self leveling for the roof/vents, and non-leveling for the edges...we have a TPO ROOF.
