Hackberry tree split and fell

We were called out to remove a hackberry tree that split and fell on a customers house.  These trees are very prone to splitting and this is a perfect example.  With no crane access to the tree American Arborist utilizes other tools to get the job done.  Here we are using a GRCS winch to lift the tree off of the roof. This log weighs around 1200 lbs.  Watch how easily it lifts it.

Directly under the log is a sliding glass door and a concrete patio, so the log couldn't just be rolled off either.
