Climbing on Roofs?

Today I decided to look at some job postings just to see what is out there. I was looking at one job and noticed the following:

PHYSICAL REQUIREMENTS
Subject to relocation.
Occasional long, irregular work hours.
Travel, including overnight travel, as required.
Repeated use of PC, telephone, and office machines.
Extended periods of sitting and concentrating.
Regular bending, twisting, crouching, pulling, pushing, and reaching in an office or field environment.
Regular physical activities, including lifting, carrying, and using a 35-pound ladder, as well as climbing on roofs.

I don't know about you, but I don't necessarily consider regular physical activities to include climbing on roofs.
