<div>Hello Wrenches,</div><div><br></div>Installing rail mounted PV array on a 2 1/2 / 12 pitch EPDM residential roof. It's a flat section of roof in the middle of the house. Need to keep it low so would like to use 3" or 4" Unirac standoffs. The standard 1-6" peel and stick witches hat is fine for a 7" standoff but too tall for the 3-4" standoff. Unirac and Oatey have advised against using the Oatey aluminum flashing although the roofer who did the roof said it would be OK using seam tape between the Oatey and the EPDM. Another roofer I know has said absolutely not. <div> <br></div><div>I did find a rubber Masterflash (6" x 6" base) that's a good fit but all their images show it used on metal roofs only and it's not a peel and stick. Can I use it with seam tape and/or caulking.</div> <div><br></div><div>Do I just need to go with the 7" standoff and the standard peel and stick witches hat and forget the low profile?</div><div><br></div><div>Or is their some other system out there (roof attachment/flashing) that would keep it low. The ridge height is already at the 35 ft limit and the upper row of mod's would go above the ridge with the 7" standoff.</div> <div><br></div><div>I will work with a roofer but would like to figure this out before just turning it over to the roofer</div><div><br></div><div>Very much appreciate any thoughts.</div><div><br></div><div>Thank you and Happy New Year to you all.</div> <div><div><br></div>Larry Liesner<br>Design and Installations<br>Elektron Solar, LLC<br>49 Richmondville Ave Suite 107<br>Westport, CT 06880<br>203-557-3127 (office)<br>203-644-2404 (cell)<br>203-549-0977 (fax)<br><a href="mailto:wirewiz@gmail.com" target="_blank">wirewiz@gmail.com</a><br> NABCEP Certified PV Installer (# 032611-184)<br> </div> <hr>___________________________<br>
