I will be doing an exclusion on a cabin in mid August. We've substantiated five entrances/exits and two more suspected. This cabin has several additions and gaps abound. Most of the sealing can probably be done with Pur or similar foam, but I am concerned about the ridge cap. It is a metal roof and there are droppings pretty much along all of the ridge cap.
This is not a ridge vent. My main concern is the likelihood of bats crawling under the cap and finding gaps in the sheathing beneath to enter the attic through. Initially I though I'd foam all of the gaps under the cap. That would require a tremendous amount of foam and then I am still concerned that they could enter roofing ridges at the eaves and work their way up to the ridge to enter the attic anyway. I've thought it may be easier to remove the cap and then just seal any gaps in the sheathing. The bats could still get under the cap, but would not be able to enter the structure proper. Your input and experience would be appreciated.
There are also several chimneys on this structure. There is no indication the bats are using these (though they are entering under the flashing of the one in the pic). Would I be right to assume they need capped anyway as the bats may likely start using them when they can not enter the structure as before? There are ALOT of coon in this area (remarkably they've not had them in the chimneys) and I will try to sell them on commercial caps as a preventive for the coon as well as to keep the bats at bay.
Your input and experience would be appreciated.
