The surface temp is no joke. Before we lock our car at the parking lot , we use towels to cover our leather seats , leather steering wheel etc. Interior temps inside car can cook bacon and eggs right on the leather seat. 3 days in June one year I had a complete reroof. For 3 days 5 roofers looking like ninjas worked 8-4 only taking a 30 min break to sit in their work van to have lunch. I advised these hard workers in Spanish if they needed to use my bathroom just let me know . They never did , their work van never left my driveway during those 3 days. The temps each day was 98,95,96. Up on the roof was surely triple digits. They did a great job. Who knows , maybe my landscaping got fertilized during that time.
