Crawling through attics has got to be my least favorite part of the job. Older houses tend to have quite steep piched roofs, giving room to stand up in the center, but due to age they're usually absolutely filthy up there.
Newer single-storey homes here tend to have much shallower pitch roofs, often the trussed type. The sheer quantity of struts and supports makes crawling through the already limited space very difficult at times, especially when the owner has had an extra complement of fiberglass insulation added so that it's almost impossible to see where the rafters are located.
Crawlspaces aren't nearly so common here, as many newer houses were/are built with solid concrete floors.
