I work for my ex, managing his Pest Control company. Here's a pic he took from a job site yesterday. A customer called and said she had "rodent damage". When he got there and saw this, he obviously realized this wasn't from rodents, and referred the job to a friend of ours who deals with wildlife pests (we deal with insects, mice, etc., where as our friend does things like raccoons, bats, squirrels). Our friend later told us that a raccoon did the damage, which is what we figured. This is the roof of a woman's house by the way, not a coop or barn, just her home. So the three of us got into a discussion about how this happened. Our friend said that when he went up on the roof it was clearly rotting because he could feel the give beneath him and was afraid he might fall through. So I said that my guess is that there must have been some damage at that area, such as a hole, lifted shingles, etc., that the raccoon picked at until he was able to completely dig through. Our friend said he disagreed, that a raccoon could just dig through a perfectly sound and solid roof and do the damage you see pictured. My ex/boss thinks that maybe the raccoon smelled the rotting wood and knew it would be soft enough to dig at. I joked that if we could get some crime scene detectives out there, that my guess is they would be able to piece that roof back together and find that there was some sort of existing compromise to that area of the roof that the raccoon saw and went for as the weak spot. So I thought I'd ask you guys to play detective with me. Do you think: 1. That there must have been some sort of compromise visible, damage, a hole, lifted shingles, etc that encouraged the raccoon to dig? 2. That there was no visible damage at all and that the raccoon just randomly chose a roof and dug the heck out of it until he got in? 3. That the raccoon could smell the rotting wood under the roof and although there was nothing visible, knew to dig because of that? 4. Other theories? Personally, I think there had to have been something there to tell him it was compromised. I'm not saying he couldn't have done this damage otherwise, but I'm not sure he'd have much incentive. Why would he just randomly choose what could have been a good solid roof and start digging a hole like that? I think it's more likely that he knew this roof could be dug into with little effort. By the way, nothing was found in her attic as far as seed, feed, or anything that would have attracted the raccoon other than the attic space itself. So what are your thoughts? I'd also like to hear not just what you think is possible for a raccoon to do, but also what you think is likely the motive for this raccoons' crime. Or is the criminal even a raccoon? Other possible suspects??
