Why a roof inspection is important

Yesterday I completed my annual roof cleaning and inspection. I found two black slightly humped spots on the roof. They looked like the typical mold/mildew spots that roofs get during the year that usually just wash off. These were odd as they were slightly raised. I scraped at them with my fingernail and they just popped off, leaving a small divit in the roof material. Closer inspection showed that they were probably hot embers from a campfire that had melted into the roof. Now the roof material is slightly thinner in the two spots. A small square of eternabond will fix it, but it is still leakproof at this point. Another lesson is to keep your campfire small and away from the camper if possible. It really would be nice if the manufactures could actually come up with a more durable/leakproof/check twice a year proof roofing material. I would gladly pay a bit extra.
