Re: [RE-wrenches] concrete roof tile install

2017-06-24 Thread Jason Szumlanski 
Off topic, but are you aware that Geocel 4500 lacks testing to ASTM
standards? An AHJ dinged us on that, despite the fact that the product is
specified and recommended for the application. The funny thing was, we
originally submitted NP-1 with our specs, which was not suitable for the
metal roof. That's why we wanted to use Geocel 4500.

Re: [RE-wrenches] concrete roof tile install

2017-06-22 Thread Jason Szumlanski 
I like the idea of tile hooks, if flashed properly, but they are not
suitable for high design wind speed environments in my experience. Unirac's
tile hook tables require anything over 140mph to have effective spans of 24
inches when trusses are 24 inch on center (32 inch for 16 inch OC). That's
way too many attachment points to make economic sense for us here. I
haven't seen any other hooks with longer spans. Since most of our work is
160mph+, it's not an option. And Unirac's span tables only go to 170mph,
which eliminates much of SW Florida and pretty much all of Florida's
southeast coast. I'm not sure about snow and seismic, but I imagine there
are similar issues.

We do flat tile roofs all day out here in CA. We've used these flat tile
roof hooks by Solar Roof Hooks
 to great
success.
Pull up a tile, find a rafter, pilot holes, goop, put in a hook with lags,
more goop, and then a piece of roof-flashing tape for good measure, put the
tile back and move on to the next one.
No issues with leaks so far.

Re: [RE-wrenches] concrete roof tile install

2017-06-22 Thread Jason Szumlanski 
+1 on Quickmount Tile Replacement Mounts

We do tons of tile in SW Florida and we're in the midst of doing two
communities of new construction totaling over 450 tile roof homes right now
- about half flat tile. All are getting Quickmount replacement flashings.
There are some snags, but all in all the tile replacement mounts work well.
You have to be careful not to ding/dent/bend them or they will never lay
flat and hold their shape (this is particular to the flat tile, not the
s-tile replacements). You might consider spray painting the bottom row of
flashings to match the roof color.

And if you have not worked on flat tile before, prepare to break some. They
are not nearly as structurally capable to resist crushing as S-tile. Walk
where the courses overlap only. And new tiles are really susceptible to
breakage - like saltine crackers until the concrete cures.

Another response mentioned roof felt condition. We see a lot of peel and
stick underlayment beneath tile here, and it is susceptible to tearing
during installation of mounts if you are not cautious. And note that
Quickmount's excellent documentation and videos do not address this
underlayment type as far as I know. Since you can't unstick peel and stick,
you can't exactly slip a new sheet under the course above like with felt.
I'd be interested to see what others are doing in this case.

We have always loved QuickMount's products for flat tile. Definately not
the cheapest solution, but the robust double flashed method gives high
confidance of leak-free installation. We deal with high wind/snow loads and
they have excellent engineering specs. There are many cheaper products
usable at lower elevations (Tile-Trac for instance) but none of them have
addressed the longevity issues QM has..

Re: [RE-wrenches] concrete roof tile install

2017-06-22 Thread 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.

There a mounting systems by Quickmount and maybe Sunmodo just for tile, if
the tile is good then this may be all you need, that is IF the roofing
