[RE-wrenches] concrete roof tile install

[August Goers]

Jay - I'll add one big point to working on tiles - make sure you check the
condition of the underlayment before starting work. Tiles can last for a
long time, but the underlayment (felt paper) on older tile roofs starts to
become brittle and disintegrates. Water during heavy wind storms works its
way between the tiles and gets under the underlayment if it isn't intact.
Vent pipes, skylights, and roof transition points can start to leak.
Removing and replacing tiles in order to install the PV system can disturb
the fragile underlayment and cause problems. We've run into such issues and
stay away from self-waterproofing tile roofs that are older than 10 years or
that show signs that they weren't installed properly in the first place.

Hi Jay -

We don't do a whole lot of tile, but when we do we've switched to using a
tile replacement mount product. Quickmount and EcoFasten both make similar
products:

There are several advantages of this replacement type system. Check 'em out!

HI All,

I’ve never worked with flat concrete roof tiles before.  And have an install
that does have them.
Something like a Striata type.

Wondering what recommendations folks have for how to mount with them.  Its
not a large system currently only 6-9 x 280 60 cell modules.
Probably doesn’t make sense to remove/reroof in that area.  And the roof can
handle the weight without removing the tiles.

thanks in advance,

Jay
Peltz Power.
