 in any given year or two or whatever? Again, I go back to the homeowner. I discourage them to get on the roof. Number one, most homeowners don't know the industry, don't even know what they're looking for. Again, call us once a year. We'll come out and we'll do a full inspection and let you know if there's loose shingles, if we look like there's silicone that's going bad around the furnace vent or any kind of caps up there. We'll let you know all that and we'll take care of it.
