Help?!? Metal roof condensation

Oh my! Who pooped on your pop-tart?

While bdub's pyramid story sounds impressive. it's a crock. They picked stone because it was cheaper than concrete. It was from a quarry right at the base. Slave labor was cheap. They used concrete for the exterior finish because they percieved it to be superior to stone. The biggest pyramid has interior space of a small house, contrast that with the largest interior vollume space in the world, the Luxor in Vegas that just happens to look like a pyramid. And what did they use to achieve that? Reinforced concrete. Castles (those still standing) may have impressive looking exteriors, but the ineriors are tiny rooms because the walls need to be 3 to 6 feet thick.

Just because modern materials can be misused doesn't mean they automatically are inferior.

Kingnear,

You have a common problem related to metal roofs caused by one simple fact:

The metal is cold and there is an inadequate vapor retarder on the inside.

As long as warm, moist air is permitted to make contact with the metal, this problem will persist.

You have two fixes available: 1: Completely seal the interior insulation system to stop air infilatration to the metal roof.

2: Install an insulated roof system over the metal roof. This is the best long term solution when done correctly, and it is strongly recommended to remove all interior insulation from the ceiling and allow the metal roof, which is now a roof deck, to breath on the underside.

Your metal panels are probably starting to rust badly, which may be why the coating was ed in the first place.

For future reference, one good general rule of thumb is: A roof coating is only as good as the surface to which is being applied.

bdub.....To say "well said", is an understatement....

Good words bdub. B)

My opinion is that this is yet more evidence of the result of our current lack of wisdom or at least the lack of application of it to the building trades. All permanent or long lasting roof systems which are proven to last, rely on breathability among other "common sense" fundamentals. I believe if roofs could simply be painted on, our forefathers would have discovered this long before figuring out intricate systems such as slate or clay tile. We create new products today from our demand for cheap, fast and profitable. Although this force is much stronger than demand for sound, proven, long lasting, beautiful and responsible, I believe simply out of ease of installation, our fathers and grand fathers would have come up with things like grace and elastomeric if they believed they would work. What "works" to them came from proof not brochures like today. I have seen paints and peel and sticks work well for temporary patches but as roof systems, they violate all proven techniques, historical data and sound fundamentals. Another related example is the pyramids. Concrete and casting technology existed then,so why, with "primitave" tools did the builders choose solid stone of such large dimensions? Because they knew that concrete is mortar, not building blocks. They even knew that stone and mortar is a weaker installation than dry stacked stone because dry stacked stone allows for movement and movement is in the same box of fundamentals as breathability. Both of those fundamentals are observations that require wisdom and are a big part of the key ingredient for debunking the current ways of projections and well written claims. Shoot, today the mortar has become the brick and even words like "cement" and "concrete" create to us images of solidity and permanance. When we see those gaps and voids today, we fill them with caulks or spray foams. This is us with our extremely limited understanding and shallow intentions molesting wise and well proven fundamentals. The evidence is all around us. Things built hundreds of years ago are still proudly standing while homes built 30yrs ago are being bulldozed or at least have many embarrassing problems like condensation and settling damage to which modern contractors are quick to create more modern "solutions". In short I have to say that its rather easy to witness todays "machine gun" approach doesn't hold a candle to the single well placed round approach of yesterday. Today we always save money up front and it always costs us more in the end and we become fools in the process. But were too distracted by our big tv's and I phones to notice.

Cont, What the heck are you talking about?

we always look for the patient contractors, fair prices and time utilization with good wages segment and your products also seem diversified in their representation!!

Is it a heated building?
