Thanks for the reply @ANE91. I guess my question was what fetch length I should be taking to calculate windward snow drift (wind left to right) at low roof parapet when my capture wall at high roof is not tall enough to capture all snow per capture wall commentary in ASCE 7-22, Figure C7.7-2. I...
Yes, I couldn't find any code reference for this particular case. So I'll go with a conservative design and take max fetch length of the high roof + low roof. Thanks!
I have a situation with both a low and high roof, each with parapets. Upon reviewing the high roof parapet as a capture wall, I found its height insufficient to withstand the snow drift. According to ASCE 7-22, Figure C7.7-2, I am experiencing leeward snow drift; however, the code does not...
