Metal roof repair

This was on the local news. It will cost Sullivan county $200,000 to remove the metal roof, replace the plywood underneath, and replace the insulation on jail. If the video works, it will also show rust under the metal. The metal they are removing looks good, so it may last 50 years. Guess the contractor who installed the metal roof didn't know what they were doing, right?

I've seen some contractors put metal over existing shingles, some even put 1/4 inch fan-fold over the shingles first. I will predict that there will be more of this happening in the future because metal roof are becoming popular. I'm sure some will say they have had metal roof and no problems. Metal really isn't the problem, the problem is humidity.

Indiana has a humidity problem that some of you don't. This morning schools are on a 2 hour delay. When the dew point and air temp are the same, you have fog. You will also have condensation, yep even under the metal.

Check to see if they have to pay each employee the "prevailing wage", which can amount to $30 an hour or more total, or more. Or more.

Its easy to complain about, yep prevailing wages, (of course those guys in all the trades don't deserve a decent wage, up on a roof, hot, cold weather, fall hazards, sharp metal, dust dirt and debris + all the other things construction trades encounter) Realize that whether its union or non, prevailing wage, most of these companies are highly productive, perform their work to meet the specifications or criteria called for in the contract documents. Working in occupied facilities like this also presents a myriad of challenges for the contractor, security is the main one, coordination, and out of sequence work, as well as any lock downs or incidents that will stop work, its no fun being a worker in one of these places and they lock it down.

It takes a well run municipal design and construction entity, facility planning or whatever this county would have to make these jobs go smoothly, insuring the bids are fair, represent reasonable costs, not unbalanced or with gross errors, flaws or are incomplete. Additionally, the design is just as important. NYS has an excellent D&C behind correctional facility construction, new buildings or just the typical maintenance and smaller but very necessary contracts. Their system is very efficient and the agency has great people at all levels to insure that the taxpayer money is well represented. That is not to say other agencies may lack, some do, and I have worked with many, the one that handles correctional facilities is top notch, and has been for as long as I can recall. Not a lot of people know this because they never worked with them.

I don't particularly care for the fact we have to house some of the worst as well as minor offenders, on our tax dime, but I sure as heck don't have another solution and that is another discussion not suited for here anyways.

In our state, their facilities do seem to set the standard for counties as their designs are very similar.

Roofing details for the buildings in this state, at least every correctional facility I worked on, ($250M worth of new buildings) has a very stringent specification for roofing. Fabral is the specified manufacturer for standing seam metal roofing, no field cutting is allowed, every piece must have a factory finish or its rejected, and the entire roof deck is covered in WR Grace Ice & Water Shield. The entire roof is covered in it, both these materials are specified, if the contractor submits an as equal, its difficult to get it approved, they don't particularly care to deviate from whats specified, often time rejecting materials. NYS learned from their mistakes at these facilities with inherent and widespread roof problems in the past.

The installation and or construction is closely monitored and documented, and they have certainly resolved their roofing issues, as well as many other materials or building components specified. Their specifications are posted publicly and are great reference material given the great job the specification writers did. Nothing is perfect, but they sure did seem to do a great job across the board.

you want a metal roof to last screw down 1 by 4 every 30 ins across and then the steel it can breath then

I could not get the video to load ?

Right now my house roof is shingles and in bad shape. What scares the heck out of me is who do you trust to put on a new roof ? All I ever heard was whoever looks at a roof they always say the other guy didn't install it right ? Shingles or metal. So I really wonder if anyone knows how to do it ? And then the quality of products out there is scary too.

What is wrong with prevailing wage? Do I sense a little jealousy?

Mike, try the new link. I had it playing when I copied the address. You have to watch a commercial first. You should get the new clip I watched last night and it shows them removing the metal, shows rust under metal .

This isn't the first I seen metal roofs removed and shingles put on pole barns. There was a local church that removed the front of church that had a metal roof. Mold caused by condensation required them to tear everything down.

I was thinking of putting concrete siding on a room addition. Then I googled concrete siding and found a class action lawsuits. Concrete siding trapped moisture, mold. I may not live long enough, but I'm betting metal roof may someday be in a class action too. $200,000 to replace a metal roof is an expensive repair.

You will never sell me metal, period.

If link doesn't work google sullivan county jail , WTWO news

MikeM,
There is a lot of buzz about 50 year metal shingles. There is a class action against one brand.
Check this out.

There is always a situation where there is an unexpected reaction between materials.
Some years ago we had to have a metal roof replaced because the underlying insulation
caused the metal to corrode. It was covered by a class action suit. Another was siding
on neighbor's house. Was replaced under warrantee because the bare aluminum showed through.
Unfortunately some things don't surface until time goes by.

+1 on this idea.

You must not know extreme humidity areas very well.
I have seen carports made out of metal drip water.
You can not get more ventilated than a carport.

...and modern materials contain fiberglass, petroleum products...maybe we should all just go back to canvas or sod houses...(sarcasm???, haha) Face it, nothing works forever, I guess is the moral of the story...maybe I'm missing something...

Yes that will happen when dew point and air temperature is the same,you have fog. A rain clouds on the ground. Water gets everywhere. If you have that problem good luck keeping moisture out.
