Condensation Causes Mold on Cathedral Ceilings

mold on cathedral ceiling

We see a large number of Overland Park homes with mold on cathedral ceilings. Condensation is the primary cause. Most often, it is due to the lack of insulation in the ceiling. The lack of insulation causes warm and cold air to meet and create condensation. The condensation creates mold. Check out both of our videos about the removal of mold on cathedral ceilings.

Video #1: Removal of Mold on Cathedral Ceiling 20 Feet High

Hello, Ben Fetzer with Fresh Start Restoration. Getting ready to start a high 20 foot in the air mold removal project. We’ve got mold on a beam up in the ceiling. He can see our containment goes down about 20 some feet. We’ve got scaffolding set up. We are going to be going up here in just a second. Negative air right there, going out the window. We’ve got furniture covered up and we’re about to go in here and get started. So, this is the situation with mold on cathedral ceilings. Ben Fetzer, with Fresh Start Restoration or

Video #2: Removal of Mold on Cathedral Ceiling 17 Feet High

Ben with Fresh Start Restoration, I’m doing another ceiling mold removal project. Uh, this one is smaller than the last one we did but similar as far as the cause of the mold. We think it’s simply condensation, uh, that is a building up on the ceiling. It’s vaulted ceilings, so no attic or insulation.

This is the second time I’ve seen this in the case that the roof has gone from a roof shake the wood shake shingle to modern asphalt shingle, so they changed the type of roof or the type of shingle that was on the roof. And as a result, um, for some reason the beam starts to have condensation build-up as well as the ceiling. So there’s something correlating to the changeover from roof shake or excuse me, wood shake shingles to composite asphalt shingle. And um, in both cases we’ve got mold on the bottom side of the beam.

Um, we’re still working out exactly why that is, but that is one common theme in these situations. We’re going to be trying to wipe that off with a professional-grade mold removing peroxide product. Um, if not, we’ll take a grinder to it and will grind the paint in the mold right off a, we’re also gonna open up the ceiling and make sure there’s no mold on the backside or top side of this drywall.

We can tell the texture, it’s just falling off from humidity and probably years of, I’m just breaking down over the years. I doubt that they’ve got a roof leak and I doubt that, uh, this is related to anything other than condensation. So we’re going to know in a little while, but we are up, uh, I’d probably say 17 feet off the ground. You can see the ceiling fan. They’re below is our negative air machine, covered up some furniture and the curtains and um, we are under negative pressure. So, um, anyway, this is Ben with Fresh Start Restoration. Can see the size of our, a containment wall. It may extend my arm out and um, we’re up here on scaffolding. So Ben Fetzer, Fresh Start Restoration or
