Asphalt Roofing


Fast, friendly, & affordable is what you can expect from Heyn Brothers when it comes to installing your new roof system. We will be prompt with getting you a quote and letting you know all of our available options. We have a full production team that will get you on the schedule in a timely manner and fit your needs. At Heyn Brothers we go out of our way to complete the project in 1-2 days on most jobs. We however never compromise quality during the fast & efficient process.

Heyn Brothers has been chosen by two of 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 Master Elite Contractor with GAF, which is their highest possible rating and only held by 1-2% of all roofing contractors. The GAF American Harvest roof system is our standard that we install. We offer the Weather Stopper System Plus warranty with every American Harvest 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, which come with a Golden Pledge Warranty. Only GAF Master Elite roofing contractors are able to install the Golden Pledge system. Not only does this roof have to pass our job site supervisors quality control inspection but also GAF sends out an inspector on every project. This gives you another level of commitment to quality that others contractors just don’t have. When the project is complete, passes our inspection, & passes the GAF inspection you will receive your Golden Pledge warranty. This warranty comes with the same 50 years non-prorated warranty on material defects, but also includes the 25 year Workmanship Warranty.

We are a highly credentialed roofing company that has attained the Master Elite status and provide a variety of top quality products for your home. This includes our luxury GAF Woodland and Sienna shingles.
