@ Peter and Gabriela I have already made use of pitch, having used "slope" for "pantă", and adding in "pitch" to enhance the description of 29 degrees:
"...creating the sloping concrete roof with its pitch of 29 degrees"

It is really "variable" that I find confusing. Do they use it in the sense of "gradual" maybe? The use of "variable" in Gabriela's link seems to describe a way of assembling roof panels that offers different pitch settings for the purpose of building a roof. I can't see how this can describe a sloping roof that is already fitted in place. That is to say that you wouldn't want to vary the settings of your roof pitch after you have constructed it.

Pentru "panta", as folosi termenul "gradient", care mi se pare mai general.
Traducerea ar fi: the concrete roof with a gradient varying up to 29 degrees.

@Gabriela De acord cu cea de-a doua propunere a ta, chiar i se zice "pitch" atunci când vine vorba de acoperișuri. De ce nu o și postezi ca răspuns?

Gabriela Raț Oct 30, 2020:

the inclination(slope) of the (concrete made) roof is variable
I also found this: variable pitch roof https://patentscope.wipo.int/search/en/detail.jsf?docId=WO19...
