Our new metal department installs a wide variety of architectural metal systems. ​We can handle projects of any size and are experienced in systems ranging from copper roofs to composite wall panels. 


Our commercial experience includes new build, re-roofing, and re-build projects large and small.  We can manage any project from a small store front, to a 140,000 sq. ft. church, to residential communities and very large warehouses.


We service a variety of clients ranging from single property owners to some of the largest property management companies in Colorado. Give us your toughest leak that no one seems to be able to repair, and we will show you why you want us servicing your properties.

Grabau Roofing is a family-owned business with the strength of over 50 full time year round employees and over 100 years of combined expertise in commercial roofing, metal systems, and on demand service.
