 flat, seamless surface to
caulk or gasket to.  The thicker and wider the flashing,
the more you distribute the downward force

applied to the bracket by weight and fasteners.  Any
voids under the bracket will have an overlapped flashing
above it.

I hope these musings help you find a solution.

We've found that in the Bay Area that deck-mount
solutions typically pencil out structurally (via a
structural professional engineer) as long as the deck is
1/2" plywood or thicker, assuming we have all the info
on how the roof is constructed. The big assumption is
that we can get all that roof construction info, which
can be difficult for existing structures.

We haven't taken the plunge yet on the flahingless deck
mount products like the Sunmodo Nanomount or Unirac
Flashloc Duo. I do think that they offer several
significant advantages including not needing to find
rafters, thus virtually eliminating missed pilot holes,
and not disturbing the comp shingle by eliminating
prying up the courses to insert the flashing.

gineering, then
in the installation, by installing more attachments than prescribed.
But the evidence is clear. It works.

Caveat to the above: I have zero experience with snow or seismic, and
no experience on roofs exceeding 8:12 pitch, and few above 6:12.

And one more shout-out to S-5 clamps on standing seam roofs. Aside
from one minor failure of the roof metal itself, not an S-5 failure,
we had zero failures of S-5 clamps attachments to report.

I hope this anecdotal information helps and sets some fears aside.

Since roofs were first thatched, the overriding wisdom is that

We've found that in the Bay Area that deck-mount solutions
typically pencil out structurally (via a structural professional
engineer) as long as the deck is 1/2" plywood or thicker, assuming
we have all the info on how the roof is constructed. The big
assumption is that we can get all that roof construction info,
which can be difficult for existing structures.

We haven't taken the plunge yet on the flahingless deck mount
products like the Sunmodo Nanomount or Unirac Flashloc Duo. I do
think that they offer several significant advantages including not
needing to find rafters, thus virtually eliminating missed pilot
holes, and not disturbing the comp shingle by eliminating prying
up the courses to insert the flashing.

or failure of the roof metal itself, not an S-5 failure, we had zero
failures of S-5 clamps attachments to report.

I hope this anecdotal information helps and sets some fears aside. Please

Re: [RE-wrenches] Attaching Array To or Through Ply

2023-03-29 Thread William Miller via RE-wrenches

Friends:

Thanks for bringing up this scenario.

I have two problems with using a product such as the easy-feet or other
deck-fastened brackets, particularly on a rigid foam-above-sheeting roof:

1. I worry about compression of the foam material over time. This could
leave a void under the bracket which could lead to leaks or wobbly brackets.

2. I don’t believe in chemical solutions for sloped-roof rain-proofing.
By that I mean the use of caulks, gaskets, etc. Since roofs were first
thatched, the overriding wisdom is that gravity is the only way to reliably
shed water. Overlapping, seamless material is the only method to use.
Caulks degrade, roof surfaces become powdery, and the rafter is often under
an architectural feature or seam in the shingles.

I researched the PLP EZ foot back when the company was DPW. The fasteners
provided were not rated for the application, according to the fastener
manufacturer. If you can match the fasteners to the decking and the
forces, then maybe you have a start to a mounting solution.

Whatever product you use, I would install it on a section of flashing
metal, lapped under the next course up. The flashing gives a flat,
seamless surface to caulk or gasket to. The thicker and wider the
flashing, the more you distribute the downward force

applied to the bracket by weight and fasteners. Any voids under the
bracket will have an overlapped flashing above it.

I hope these musings help you find a solution.

William Miller

PS: I have encountered this roof configuration a few times on flat, built-up
roofing (BUR <https://homeinspectioninsider.com/built-up-roofing/>). We
have dealt with it by cutting through the foam, installing blocking on top

Re: [RE-wrenches] Attaching Array To or Through Ply

2023-03-29 Thread Christopher Warfel via RE-wrenches

Quickbolt makes a similar product to the nano. I've used it several 
times. The last time when I was trying to attach to oak beam and had no 
experience with how difficult that was.  They work well, but no greater 
than 36" spacing.

I was just asked to bid a roof mount with SIP panels.  My first 
thought is to just say no.  I am very hesitant to rely on the pull out 
strength of screws in OSB.


I will be watching this thread.

Hi All,

I've run into a roof-mounted job where the roof is built-up with
the following:

Comp shingle
Plywood
Foam board
T&G (roof deck, but also interior ceiling)

The beams that hold the t&g up are wide-spaced and not convenient
for fastening the full extent of the array.

This being the case, I was considering other fastening options and
am writing to pick the collective brain of the Wrenches to see how
others have addressed similar situations.

One thought I had was to use the PLP Easy Mounting Foot and I'd be
glad for any opinions on that or another solution.

Matt,

            I guess my questions are 1/2" plywood or 5/8" and how thick 
is the foam?  Oh and I assume its nominal 2X6 T&G?  Do you know how the 
plywood is attached?.through the foam into the T&G?... to stringers, 
nailers or whatever they're called?

You might want to replace the screws with something shorter and 
beefier though to get more grip if you are only going into 1/2" plywood.
