About six years ago I asked during our reserve study walk around about 
replacing our roof with metal. We have some sort of decorative metal now. It is 
more expensive but with care should last “forever”. 

But the two things he said that I didn’t know is that the new metal roofs are 
insulated which both dampens the sound of rain but also is a two for one 
purchase. And the metal roofs with ridges, or at least some of them are 
designed in the right dimensions for solar panels to be be attached.

On snow falling off, if you’ve been in rural areas you might have seen a 
decorative iron spiky things (a technical term) sticking up around the roof 
line. Those are to first keep the snow on the roof and when it does fall to 
slice up the snow o it doesn’t come off in one sheet. The snow insulates. Think 

I decided to look them up — they are called snow guards

The newer ones fit closer to the surface of the roof.
