Have you checked out Eco Fastens ECO-65?  It's a large plate with 8 screws and 
it's got flashing for both asphalt and membrane roofs.

Subject: [RE-wrenches] Sheeting-attached roof mount

Friends:

I see two issues:  Strength and sealing:

Strength:  I have researched sheeting attached roof mounts.  Direct Power has 
their "Easy-feet" product.  It relies on a specific fastener made in Canada.  I 
contacted the screw manufacturer and they disputed the claims DPW made.  Their 
testing was for a minimum 1" penetration in wood.  You can't get 1" penetration 
in 5/8" of sheeting.  Also, I don't believe that OSB can hold a screw like 
solid wood or even standard laminate plywood.

I reported this to DPW.  They were concerned enough to call me back.  They 
claim they will be doing their own pullout testing and in fact it was going to 
be available in the near future.  I don't know if they have completed it yet.  
I know DPW to be highly reputable, so please don't think I am impugning their 
products, just reporting what I discovered.

Sealing:  to flash or not to flash.  That is the question... that has been 
discussed in this forum before.  With any hole in the roof, I need to satisfy 
myself and I need to satisfy any roofer who holds a warranty on the roof.  I 
have made enough holes in roofs to make me loose a night's sleep with each 
first season storm.  The cost of one roof leak can erase the profit from 5 
installations or more.  If you add up: removing the system for repairs, drywall 
damage, insulation replacement, carpet, furnishings, artwork, etc., you soon 
realize there is no room for doubt.  A qualified roofer will have the same 
concerns and economic interests and I doubt they will allow a non-flashed roof 
mount.

We have been discussing amongst our crews some method to flash a 
sheeting-attached mounting foot.  We never finished the design.  Is there a 
flashed, sheeting-attached mounting foot on the market?  If so, I'm a possible 
customer.  If not, I can't take the risk.

William
