Testimonials From Our Satisfied Customers


Positive: Quality, Value, Professionalism

"Another 5 stars for Grennan Construction! After a great experience with Grennan's team installing our new roof, we had them install gutter guards. We'd looked at several types from several suppliers and these won hands for value and performance. Fred and the Grennan go all out to take care of their customers. I feel like they're family to me- Good family! Highest recommendation for your roofing, siding, and gutter needs!
