Best Condensation Solution for Metal Roofing

[@robertlane6675]

I am building an 8 by 12 wood fired sauna. Even though I will have a vapor barrier I justed ordered metal roofing with dripstop. For the price I think it makes sense. I hope a good vapor barrier, good venting and dripstop will prevent condensation issues. I am glad that I saw this video.

[@JCcanU]

Robert Lane , I would use 3/8 plywood and 15# felt than steel , you do not want anything like foam board over head celtec bubble wrap anything that can melt in case of a fire . I just did a pole barn using 1/2 inch plywood and 30# tar paper they use gas torch a lot and work with flammable products.

[@therealandrewlund]

In my experience with a northern midwest climate, metal roofs will sweat regardless of the ventilation. With enough ventilation, an occasional sweat may not ruin your home, but it will happen. The only way to prevent it entirely (that I know of) is solid sheathing directly under the metal. OSB, felt, metal, with no air gap.

[@thegreenman4898]

over here in ireland we get roof sheets with 4 inch rigid foam insulation bonded to the underside, and always use felt under the steel, because its a wet climate its essential

[@hogwatch5202]

You should use a tape like decking tape on the top of any timber where it is in contact with the drip stop fabric. This won’t alter any condensation build up but will prevent it from being wicked away into the timber and the timber becoming wet.

Raft-membrane-a 50x50mm bar is stuffed on top of the rafters on top of the membrane-then across the board 25mmx100-150 mm and only then a metal sheet, so that due to the 50mm gap, the roof ventilation is provided and the condensate dries.

Thanks so much for sharing this Dude. Was never sure whether those wet streaks on timber was condensation or leaks!

[@jakeschisler7525]

I've never seen that stuff before. My building came from Menards, I could have bought their insulation which I believe has a plastic film with insulation inside for walls and roof. Only thing I didn't like about my building was the fact the contractor used ring shank nails instead of screws. My building was 30x54 10 feet. It was very cold in wintertime and I used a salamander while in there. I had 3 cars, a tractor and boat in their at different times. Wood working tools and lawn care stuff. My building here in Florida is 40x60 one side is enclosed with an upstairs but other part just has a roof an one side with metal. That building has seen better days. It has I beams through out. All electric is running through the concrete in pipe.

I knew of that product, where I am at it is mostly used in buildings where there is a higher then normal moisture load, either a dirt floor, or animals.

[@tommiethompson5214]

Excellent description of the drip stop material, thanks for the info. Was looking into condensation in out buildings and now realise I can’t avoid it in an enclosed small single garage space, just gotta try to lessen the effects. Just had a NEW steel sheet, plastisol coated, garage roof with drip stop. I’m sure the drip stop is doing it’s thing but the same night after the installation, we had driving rain penetrating the foam fillet at the top end of the roof sheets, the water has tucked itself under the end of the sheet and is pooling down the INSIDE of the new roof................ totally RUBBISH finish by the contractors, so there you have it, I’m pissed to say the least. Anyway, I digress. Thanks again. I just wanted to vent my anger to a professional who knows their stuff

[@dougneufeld2799]

Okay Dude we have talked before. Like your detail and timeline. Yet we discussed a few weeks back about a proper vapor barrier. If you tape the joints you will never have concern about condensation. The amount of time you take with story boards and squaring your buildings (which I may add I respect), taping your vapor barrier will have the same effect.

[@RRBuildings]

this is not due to vapor from the condition space alone... and I agree with you. this product is for those sheds with zero ceiling or insulation...you get those cold slabs in the spring and the sun hits the steel roof and you get the drip on the concrete. This will prevent that

[@dsfs17987]

@Doug Neufeld not quite right, that condensation on the metal is due to temperature difference in the attic vs the outside of the steel which is directly exposed to fresh cold air, the air even in a fully vented attic is always a tiny bit warmer than outside, this makes vapor from the fresh air condensate on the underside of the steel here in the old world we use something similar to a house wrap, it is a plastic/fiberglassy sort of type film that has the underside of it covered with this felt type material, if anything drips from the steel on to the glossy top side of the film, it either rolls down, or if passes through, stays on the underside of the film till dries out, there is a vented air gap between the steel and top of the film, and a 2" vented gap under the film, only then the insulation is placed, which is the usual setup - the wind barrier, then the insulation (no less than 6" of rock/fiberglass, some even go up to 16"), then vapor barrier, then the inside paneling, if the house is going to be air conditioned, then there is some 2"-3" insulation between the vapor barrier and inside paneling (sheet rock/drywall) to stop vapor from condensing from the outside on the cool inside wall

[@pierredemare609]

@@dsfs17987 Great comment! Good points. So, venting is key. But what if there is no wind? How about a fan in the attic for those days? My situation is a bit different. I am in the Tropics. The seamless metal roof I am looking at can come with a foam like 5 mm plastic foam glued to the roof panel. I am afraid that the glue is going to peel off over time (as the heat hits the roof) and eventually delaminate. I will also put some kind of reflective barrier a few cm from the roof below to reduce heat inflow. That should help with evaporation, but not in the mornings so much. I am thinking venting is key. I am not 100% sure I can do a ridge vent. The last builder looked at me if I came from a different planet when I did ask, but the new one has more experience. I do have soffit and gable vents.

[@dsfs17987]

@@pierredemare609 I'm not sure about how it should be done in tropical zones, I live in a temperate region, so it is mostly warmer inside than outside, and properly built roofs work sort of like chimney, so there is no need for forced ventilation I'd guess you don't have much of a problem with this, any condensation will simply dry out once the heat kicks in during the day, best bet is go to your local city council, they should have a building department, and talk to people there, they should know best about local peculiarities

I have a lady friend who has way more money than I ever will. ( Lawyer lady) She had a pole building barn built for her animals and supplies. The Amish built it and by the time I saw it completed, she and my buddy who was her man at the time, showed me all the condensation that actually rained down inside her barn in the cold season as she ran heaters inside and brought the " rainforest" type environment upon herself. They asked me how I would have done things and about insulating etc. I had 0 experience with metal and could only think there has to be an insulation solution that they will have to undergo AFTER the fact. I never did see their solution. This Drip Stop seems lkike that would have been exactly what she needed. BEFORE getting the roof metal installed.

We built a 50x120 a few years back and they opted to go against my better judgement and not put any of the drop stop or any synthetic tar paper. Which I was glad because that just adds so much labor. But the whole inside was insulated very well and then steeled with white. He installed a waste oil burner and it must have been because of excess moisture in the air from the burner but it dropped so much from the roof that it soaked the insulation and dropped through the ceiling panels. Even with all ventilated soffit and ridge cap

[@NitroAuto77]

I know your focus is not quonset huts, but I have a new quonset hut that needs insulation and I value your opinion. The building is 40x56 and will be eventually be broken up into usable spaces with one being a wood shop. For the overall structure, would you go with closed cell spray foam, or look at something else to help regulate the temperature and keep condensation problems to a minimum?

I am a roll former that installs this drip-stop product near Henderson, MN. The critical part of this product is it needs time to evaporate. If you have a situation like a calf or milk cow loafing barn where it can potentially reach a point where condensation is developing a lot more then evaporation then you have a nightmare. It will start raining in your building and it wont stop. This product has it's place, but I personally don't recommend dripstop in animal confinement barns that don't have adequate air movement to evaporate the condensation. For every 25 customers there are 3 that are not happy with this product, because of this issue. In these situations where it doesn't evaporate on time, double bubble insulation tends to work a lot better.
