Heyn Brothers has been chosen by the top shingle manufacturers to have their highest credentials. That means we are able to offer a better warranty on your roof than other contractors in the area. The reason they give us these credentials is that they trust that we will do a great job for you. The reason we offer these warranties to our customers is to give them peace of mind. Our asphalt roofs come with a 50-year non-prorated warranty and up to a 25-year workmanship warranty! Our warranties simply cannot be beat!

Heyn Brothers is a Select Shingle Master with CertainTeed! That means that you will get the best possible shingles on the market with the best warranty. CertainTeed has all sorts of styles to choose from and are made right here in Southern Minnesota.

The Landmark Pro is our primary line of shingles and has max definition color and is heavier than most shingles on the market. With this shingle you will get our 50-year non-prorated warranty on all materials and our 7-year workmanship guarantee.

The Northgate shingle is our newest offering for shingle choices and again offers max definition color but also is a SBS modified asphalt shingle and is unmatched by other standard asphalt shingles. The rubberizing aspect of SBS allows greater flexibility so the shingles resist cracking even in extreme cold-weather like we have in Minnesota, allowing for year round application. SBS also offers superior granule adhesion, which is one of the key components in protecting the shingle against the elements. This shingle comes with our 5 star warranty, which is a 50-year non-prorated warranty on materials and a 25-year workmanship warranty.

Heyn Brothers is a Certified Contractor with GAF. The GAF Timberline HD roof system is our standard that we install. We offer the Weather Stopper System Plus warranty with every Timberline HD roof we install. This means that you have 50 years of non-prorated coverage on your roof system.

Our next level of roofing excellence extends into the GAF luxury line of shingles. Two of the luxury shingles that we offer are the Woodland & Sienna shingles.
