after a few requests, i have not been getting any feedback from Direct Power
regarding pull out specs for their 'easy feet', which i need for my engineer to
be able to give me the go-ahead to use them.does anyone care to comment on the
fact that this mounting method only attaches to the roof decking and not the
rafters?
i have always been under the impression that if you only attach your racking to
the roof decking, it (the decking) could 'rip right off the roof' in that worst
case scenario wind storm! but by anchoring to the trusses, the whole roof
structure would/should withstand the wind load. or maybe i was just under the
wrong impression and the spiel was that the decking would not hold the screws
and the screws would pull out!so am i to understand that by using several (of
the right size) screws at each anchor point, the decking (if adequate) will be
able to support an array (even if tilted up to 60 deg)???
cheers,benn

I have also had a great experience using "Easy
Feet" from Direct Power. You use four of their screws per foot and Jeff
Randall there can give you pull out specs in roof decking, as I recall they
match or exceed that of the Lag/rafter combo.

Antony,
Right on! The Eco-fasten will solve the issue - it's been pull-out
tested sans-rafter penetration. Have bought the eco-green fasteners from
them,
will again. As far as dealing with them - it's a great pleasure to be
able to talk to someone with good product knowledge
that will take the time to answer stupid questions.

Have you looked at EcoFasten mounting. They have a
mount that uses 8 screws per attachment, so can theoretically hold without
going into the rafters. Then could use a large flashing over that to
integrate with the shingles.
I think they're an offshoot of AlpenSnowguards in Vermont. We
started working with Alpen to source S5 clamps several years ago, and have
found them great to work with.
We're a West coast company - there were lots of other distributors
closer, but Alpen got and kept our business. It's kind of funny - when
I call them, I feel like I'm talking with someone in one of those old
hardware stores with everything you need right there in bins, and when I
call the other guys it seems like someone in a sales office who never
handles the product.
The EcoFasten crew is similarly helpful, and they have some well
thought out products. The name I have in my rollodex is Chris Sterns,
at 877-859-3947.

Their
website is pretty comprehensive, and includes leak and load tests and
building code info. Other cool mounting products too.
