Pros
There really are none. This is an honest review.
Cons
The owner will make himself sound really cool at first. He will throw out big names. He will hide his true character. Trust me in this. But he will eventually show his true colors. He is dishonest, and outright lies to people. They DO NOT truly care for the customers once the roof is installed. BAD MANAGEMENT. They will pay attention to you if you are making them lots of money. They talk bad about their employees behind their backs. This is a fact, and not heresay, nor a vendetta. The owner is the absolute worst person I have ever worked for. GP Construction is NOT a company. It is more like a Dictator running a group of peons. You will make them money, and they will find a way to get rid of you before you collect, and then because of the contract that is only in their favor, they won't pay you commissions. DO NOT TRUST THEM. I have seen it OVER AND OVER. They talk about Christ, but have the opposite character. This is not a vendetta against them, but truly to warn you to stay away. VERY Lawsuit / litigation happy. THREATS OF LAWSUITS from their lawyer.
