Tree Guy Put A Hole In My Roof

[Tangie A.]

Yep......just what the title says. I'm having a tree removed from one of my properties and the tree company accidentally dropped a limb which hit the roof and made what he described as a "hole" in the roof.  I'm literally omw to the house now to see it for myself.  From the pic he sent me it looks like a deep dent in the shingles, but he's calling it a hole, so I'm going with that.  My question is,  what now???  He offered to "run to Lowes to get what he needs in order to fix it" but somehow I don't think that's the correct answer.  I've never had to file an insurance claim or anything like that ever in my life, and I'm a fairly new investor,  so new territory here.  Grateful for any guidance on this.  I literally do not know what next steps to take.

Thanks
