About Us

Gutterman Enterprises was founded in 1985 with the mission to provide gutter services you can trust. From professional design and installation of new gutter systems to repairs and maintenance of existing gutter systems, we can do it all.

In 2005, Gutterman Enterprises was purchased by Sierra Roofing and Solar and now operates next to Sierra under one roof in Dublin, CA. The purchase by Sierra was mutually beneficial since we can now depend on each other for high-quality roofing and gutter work. We are now a one-stop shop for your residential or commercial roofing, gutter, and solar needs. And with our combined resources, we can offer Same-Day and 24/7 Emergency Service.

Why Gutterman Enterprises Is Trusted Since 1986?

Level Gutters

We install most of our gutters without a “wing,” which means that the metal flashing that goes under the roof is not attached to the actual gutter. This allows us to make precise up and down adjustments when installing your gutters to ensure that the water is flowing in the proper direction.

Rectangular Outlets

The downspout is not the “bottle neck” in your gutter system… the outlet is. The outlet is the piece that is installed into your gutters above every downspout. The water flows through the outlet into your downspout. Most gutter companies install 2” round outlets in your gutters, because it’s quick, easy, and cheap. We install 2”x3” rectangular outlets. It takes us a little longer, and it’s a little more expensive to install these outlets, but they allow for 66% more water flow out of the gutters and into the downspouts. We’ve found that this helps to cut down gutter debris buildup and overflowing water during heavy rains.

Lifetime Leak-Free Guarantee

We offer the best guarantee in the business — a Lifetime Leak-Free Guarantee on any gutter installation or repair. In the event that you have leaks or damage to your products, we’ll repair the problem for free.
