I have a 90+ yr old barn in Southwest Virginia. The roof has holes and needs to be replaced..so I am told. Note..I am 65 and female but want to make the best decision to keep this in the family for the next generation...
I think I know to select a 26 gauge metal and while the current color is more like the galvalume ..I think I will get a better warranty if I go with one of the painted colors. Is this correct?
And is there is difference in metal companies? Or is all 26 gauge metal the same or so close it doesn’t matter?
And then there is the type of metal and ribs?? Concealed or not?
And please know that there are boards under the current metal..not plywood..do I need an underlayment ?
Help me make this family landmark stand for several more generations..thank u
There are definitely differences in finishes out there in the marketplace. I would first decide what sort of color you do want and then, more importantly, vet your installer carefully.
Ideally a hidden fastener system is going to be less maintenance, but you do see some exposed fastener roofs and especially in agricultural applications.
You would want an underlayment as well to help with condensation.
I agree with Eric to select color first and make sure the contractor is reputable.
In addition, the type of paint is important. PVDF, also known as Kynar 500 or Hylar 5000 are the best for resisting fade.
26 gage with a G-90 Galvanized or AZ 50 galvalume coating is ok, but aluminum is better.
stainless steel fastners are the best for longevity.
Do you have a list of suggested specs that can be shared?? or can someone point me to that..it would be so helpful in getting quotes
The Metal Construction Association (MCA) has a guide spec available on their website. www.metalconstruction.org. At least I believe it is posted on the site under their documents. If you can't find it, just email them through the site and I am sure they will get it to you.
