Do NOT use. The company is sloppy and ruined my roof. Even worse, due to their work on my roof he VOIDED my roof warranty! When I brought this issue up to them, they claimed I told them they could cut my roof. Which doesn’t make sense because now I have to pay $5,000 to get my roof fixed AND with no warranty DUE to this company.
