No, it’s filthy debris by the bucketload raining down on all you hold dear. No one seemed too offended by my bulb advice, so here’s my advice for when you need a completely new roof (what’s known in the trade as a tear off) or any other major exterior work that will obviously damage your domestic landscape.
I think timing is key. We chose late fall because gardening is completely at an end here. No one is spending any time in the space except to walk in and out of the house. I have seen too many friends and neighbors commit to exterior work in the spring and summer and heard too many of their laments. These guys can work in the winter if they have to, and I don’t feel too sorry for them—not for what we’re paying!
Make sure they use protection (always good advice). Our roofers have clothed the sides of the house where they are working in plywood, which is slanted over the planted areas, so nothing falls into those beds. It’s impossible to protect everything though. I suppose we could have mini-teepees over every shrub.
Finally, I think the main thing is: don’t look! Keep your eyes forward when you walk in and out. It will all be over soon.
