We've got a hurricane coming our way and it looks like my part of the country is going to get hit pretty good. The most common situation other than pine tree's snapping off is oak trees uprooting and leaning over on the roof. What methods do you guys use to get trees off of houses if no crane is available(they will be few and far between for a while)? ANY ADVICE IS GREATLY APPRECIATED. I read another thread(below) about undercutting the tree by the rootball every 3 inches until the rootball is on the ground but there was no mention about how far to undercut into the tree...15% 20%??
