Congrats! I walked on mine just today. I do not have an attached ladder either, I use my home ladder and get up there easily. Twice a year I wash the roof make sure everything is nice and tight (screws / radio ant. / coax connectors etc.), take off the A/C cover and remove mud dobber nest, and check all the sealant to make sure it's good. Just be careful when washing, it gets slippery!
