I crawled on mine to install MaxxAir vent covers with no issues. Prefer not to stand for fear of stepping off the slope. Plan to wash roof the same way even though I have seen workers more than one walking around but with several feet between them. Have to wonder how they work on ac units if they could not walk on the roof.
