I have a 19 teens era Tutor Revival with some steep arches above the bedroom window.
i always hope to see who’s making all that guano but only have seen them out of the corner of your eyes on nice sunsets
the bats I have seen in my area are small little guys, like really ssmoool
anyways it’s about time to do the by annual rooftop sweeping
thankfully they stay outside, no sign they go into the attic. this is the northern side, they clearly prefer that side but we have seen some scat on the east side too. the outside layer under the roof is that 1910 style beadboard so they probably have lots of places to get a foothold. it’s Tutor brown so it’s next to impossible to see where they actually hide
