BBB is a great place to leave reviews. I would also send a private email to the business or contractor you have the complaint with. That way they are aware of how you feel and the concerns you have. If you leave w public review on Google or yelp for example Be careful with wording. Everything left on a review must be factual and able to prove just. Freedom of speech becomes libel or defamation of character.   If the contractor looses business or potential customers directly because of the review you could have legal trouble assuming they can prove negative impact. 

Have you made the contractor aware of your disappointment? Have you given them the opportunity to "Make it Right?" If so, i would go to the agency that issues licenses in your area and file a formal complaint. The BBB is also a good place to go. Both of these entities will investigate your complaint and seek to have the situation remedied.

Reviews are very important to such a company. I would advise filing a complaint with the BBB in your area as other have stated, along with sharing your experience on their other pages like google, facebook, Angie's List, etc.

Here are a few ideas....

1. File a complaint with the Better Business Bureau 
2. Most homeowners associations have message boards - post your experience there
3. Call your local TV station - they love doing stories on bad contractors
4. Put a sign on your front lawn warning your neighbors!

Everyone has a different opinion of what is good and bad service depending what side of the issue they are on.I would also give them one last time to address your complaint.

Give them an acceptable time line to respond and correct the issue one last time. If you have called them, had conversation and a commitment to correct or refusal to do anything then I would notify them in writing that you intend to report them to the BBB, and the local & state regulators. The attorney general is usually the heavy hitter on consumer complaints. Then follow through.

File complaint wth the Registar of Contractors in your area. Even if they are not Lsc they should be and can face a fine.

We recommend filing a complaint with the Better Business Bureu in your region.  If the company has any standards, this should make them and other consumers aware of the issue and hopefully they dont make the same mistake twice or no one will use them in the future.  Hope this helps. 

There are two options available for reroofing installations. One would be to tear off the old roof before applying the new one (tear off). The second would be to lay new shingles over the existing roof (lay over). While the second choice is the less expensive of the two options, it is not necessarily always the best choice.
There are advantages to tearing off the old roof before installing a new one. For example:

• If there are any defects in the roof deck, they will be revealed when the roof is torn off. These defects should be repaired before applying the new roof.

• If condensation problems exist in the attic, they too will be revealed when the roof is torn off.
Properly designed attic ventilation can then be installed in order to help eliminate such problems.

• When the old roof is torn off, waterproofing shingle underlayment can be installed before applying the  new roof. This will help protect against leaks created by cyclical ice damage and wind-driven rain.

• Tearing off the old roof and starting with a clean deck before reroofing may result in a smoother finished roof system. Although there is added cost to these advantages, each lessens the likelihood that the validity of the manufacturer’s shingle warranty will be impaired. If the old roof is torn off, your contractor should be responsible for the cleanup and disposal of the old shingles, but make sure your contract states this clearly.

If you do plan to reroof over existing shingles, first check if your local building codes limit the number of roof layers that can be applied to a residence in your area. Most restrict maximum to 2 layers. Your contractor should know the pertinent code requirements.

Michael,

Eric pretty much nailed it. 

It is not usually worth it in my opinion and especially given the nature of most leaks and the condition of most sheathing. 

Roofs aren't cheap so I think the math usually plays out that the full tear off is a better idea based on the fact that you get a better install and will likely have a roof that will last longer.
