We will work with your architect, other contractors, or any plans that you have to build or repair your roof to your necessary specifications. We will also create a specification for a particular roofing problem you have, and then build a roof to those specifications, on time and often under budget.

There are many materials that can be used on flat roof applications and we can help guide you through the maze of available options and explain the liabilities and benefits of each one as it applies to your situation, arriving at a solution that solves your problems and fits your budget.

We reroof the flat roof portion of a residential home. A five-ply system is installed with a granulated cap sheet that can be walked on. Attention to detail is evident on every job we do.
