"Flat" panel is slightly tilted anyway. A minimum 4-5 degrees tilt is needed to shed the rain water. Normally, roof has a slope to the sides, so when you conform panel to the roof surface, it becomes "tilted". Can be cleaned with mop from a step-ladder. Yes, you won't see a small poo on almost-flat panel from the ground, so checking it once in a while won't hurt. Performance will suffer until then, no big deal. When you have a proper size solar, things like bird poo, dust, or losses due to flat panel harvesting less than tilted, - this all can be ignored. 15-20% losses due to all these factors (or more than 20% if you are not in Southern states), should be included on the planning stage.
A ladder can be handy if you go for more than a day or two. I like my Werner MT-13. One of the best purchases I ever made. Works as 5ft step-ladder, or extends to 11ft. Folds compact. A little heavy though.
