About Product: Getz Fire Equipment Company located in Des Moines, IA specializes in full service fire protection. This roof was a nightmare. This roof had three different types of roofs attached three different ways with a ten-foot wall that leaked. The interior gutter between the barrel roof and the metal roof was cause for the substantial leaks until Grell got there to turn the building into a monolithic roof. Make sure to check out the before and after pictures of this roof.
