Lowes helena,mt. 59602. Don't use them. Got an estimate on my roof, they didnt provide enough materials to do the job and included materials that were not requested wouldnt take those materials back. So now im stuck in the middle of the roof having to spend more money just to finish the job i drew out plans for and provided to them. Already had to buy 3 more rolls of ice barrier and another of underlayment and im pretty sure im going to need more shingles. Of course the customer service was bent on making it all my fault. Guess its my fault for thinking they had any idea of what they were doing.
