How do you measure the pitch of a patio roof?

How do you slope a flat patio roof?
For drainage purposes, the current building codes require a minimum two percent slope or a one-fourth unit vertical for every 12 units horizontal. In other words, the roof must slope one-fourth of an inch for every 12 inches. The slope is barely noticeable to the naked eye.
What pitch should a pergola roof be?
5-degree pitch
We mentioned earlier that flat roofs are almost level. But flat pergolas should slope a little bit to one side so that water slides off instead of collecting on the roof. We call this angle the “pitch” and we recommend at least a 5-degree pitch.
