A contractor may offer you a low price but be cautious and make sure those prices don't change after the project has started. Also keep an eye on the material cost and that the price stays consistent unless otherwise agreed upon before work is done. 

This is when a scammer will require a large down payment or use your insurance coverage made out to you and then disappear with the money. A good way to avoid this is to make sure the insurance company first sends out an adjuster or only make a deposit for materials once it has been delivered.  

A prevalent scam now days, but simple to avoid. A supposed roof inspector will go door to door claiming roof damage. Avoid letting a person like this onto your roof as they can occur damage and claim to know how to fix it for a good deal. Avoid this by getting a second opinion and not allowing a stranger on your roof.  

Companies from out of town will try to rush you into fixing your roof and attempt to do as many roofs and then leave that area as fast as possible. Not only is the work poor but they will also reduce cost by using lower quality materials. Avoid these scams by taking your time and proving that a company is valid. 

Unethical contractors may invoice you a lower price and then apply for a second invoice from the insurance company for a lot more and leaving with the difference.
