I've got a spot where rain blows in along a lean to roof on my barn that I've tried closing with expanding foam, but the birds like that spot and/or the foam because they keep pecking it away. Is there any kind of foam that hardens enough that birds can't peck it? It's a prorib style roof and I've tried the closure strips that are made for that kind of roof, but the birds eat the closure strips. I'm thinking of putting in some of those bird spikes in that area, then foaming it. Problem is if that doesn't work it will be a mess to get out.
