Advice with shingles and heat

I have a genuine question. I build sheds everyday for a living, however, I am not a carpenter or a journeymen tradesmen. I label myself as a “builder” and have been doing this for 8 months. My question is, in this heat how do you walk on the shingles, I see everyone say to not lay shingles in the heat, but I only am allow myself 1 day to build the sheds and sometimes it just happens that I get stuck shingling in the hottest part of the day. I wear work boats and sometimes I can tell where I have walked on the shingles. Are there any tips or tricks to the trade I should know?

Ps- I don’t know why it says insurance related at the top. 🤦🏽‍♂️
