hello
Customer:
How are you?
Customer:
I'll be happy to assist you
Customer:
Before we get started I’d like to point out that a Professional Engineer’s standard of care typically includes a site visit to assess field conditions and get an overall understanding of the structure. This can obviously not be accomplished through the internet. The information provided here is meant for informational purposes only (general sizing and budgeting) and is based on the information provided by you. Only vertical gravity loads will be considered, no lateral loads or analysis is looked at (this can be a big part of the design that will need to be considered). The information should be verified by a professional engineer who can visit the site to ensure that potentially important information has not been overlooked or omitted.
This is not a private chat.

What kind of roof?

Customer:
Shingles are the roofing material, not the type of roof
JACUSTOMER-xt75i9k3- :
right. shingles are on top of boards
