Down my way, standing seam roofs routinely go 100 years. Without air exchangers....I'll have to disagree. 1-1/2" hail will dent steel fascia's that are on a 2x6 subfascia. Not as easy as aluminum, but it will.
I'll agree with not depending on exposed fasteners on a steel roof over a home.
I believe we all know how steel moves around with heat and cold. Just listen when the sun comes out standing by a house with steel siding.
Not a chance I would install steel directly to a roof deck. I've seen it rot out the roof deck and rust an entire steel panel ceiling in a building.
I'm not a fan of installing an air exchanger in an attic just for a steel roof which is in no way superior to a shingled roof.
What kind of windows are in basically every commercial building? School hospital shopping center hotel Aluminum/ steel frame windows. And The few high quality wood window companies out there clad there exteriors with aluminumMJW said:
If its new construction. But more often than not its 3/4 or better sheathing. All the panels are locked to each other and the drip edge so wind uplift is not a concern. The only time i have seen uplift be an issue is with some solar companies that add extra anchors or specify blocking in certain areas because you can get uplift on a solar panelMJW said:Is that fastened to just the 1/2" sheathing?
I thought I did already. We build new homes, and with 5/8 decking, we will lay steel directly to the deck, synthetic underlayment, sometimes we use a foil back insulating product, and the results, in this area, are far better then shingles. If you don't like metal, great. It is America. If you want to knock insurance costs down and not face roof replacement every few years, do a metal panel.Anyone have an answer for this? Pics would be great!
