Re: Metal Roof Proper Curb


We install commercial kitchen hood exhaust and make air fans. These come with curbs - I have tried the under over and the over over methods both seem to leak....

If in snow country, the higher the curb the better. Use lots of Ice & Water Shield. Make a cricket on the uphill side of the curb.

Re: Metal Roof Proper Curb


The installation guide from Fabral is the best I've seen www.fabral.com go to tech. Most of it can be PDF filed on to your PC. A flashing kit should come with a quality vent, but if not use the info there to pattern your own cricket from sheet stock. We have an arrangement with the local A/C guy to brake me up whatever we need.
