[RE-wrenches] Sheeting-attached roof mount

[Will White]

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.

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
