Replacement metal roof....best method

[CliffordK]

I'm an old guy, and like to keep nomenclature straight. Very little standing seam is done any more, because it requires a tinner to solder all the joints. What people call standing seam is actually concealed fastener lock seam. It's good roofing. I used it on my shop.

Different styles. But, perhaps one should specify. They all have hidden fasteners of one sort or another.

My Knudson KR-24 does a crimped lock seam. Whereas the snap lock seam is far more popular today.

I have wondered how one repairs the crimped seam roofing if a couple of panels need replaced.

Using this method keeps moisture from getting trapped, so you avoid rust and damage later on. It also makes the install look cleaner and helps your metal roof last longer.

If you're thinking about this, it's good to know a bit about roof replacement. According to As Built Roofing, tearing off old shingles and adding a new barrier before the metal goes on can make your roof warmer and prevent condensation. They also stress how important it is to do it right to avoid problems later. So you can try to estimate for roof replacement.

This approach helps to ensure that you avoid trapping moisture between layers, which can lead to rust and damage over time. It also provides a cleaner installation and can potentially enhance the longevity and performance of the metal roof.

What approach?
