Asphalt Roofs

Asphalt shingles are the most common roofing application in Minnesota. They are composed of an asphalt/fiberglass base, with a protective layer of roofing granules made of tiny stones that protect your roof from hazardous weather such as sun, rain, hail, and snow. Sever weather conditions are capable of damaging any type of shingle, so please call your insurance agent if you suspect any roof damage.

There are two main types of asphalt shingles: 3-tab and architectural.


3-tab shingles (GAF Royal Sovereign shown here) are a single-ply shingle that typically come with a 25-year warranty from the manufacturer. They weigh between 200-250 pounds per square, and can be expected to last any where form 15-18 years. Severe weather, bad insulation/ventilation, and poor application can take years off of your shingle's life.

Architectural shingles (GAF Timberline shown here) are grabbing a larger and larger portion of the shingle market each year. These shingles are thicker and heavier than the 3-tab variety and typically have a laminated 2nd-ply to help with roof protection. These shingles come with a 30 (up to lifetime) warranty from the manufacturer, and you can expect to get 20-25 years of protection from these shingles. Most of these shingles also come with shadow accents or other color enhancements within the shingle that really make the roof stand out. This upgrade usually runs from $500-$900 per house.

This type of shingle is also available in 40-year and Lifetime options as well. The shingle thickness increases as does its durability. These shingles are typically reserved for higher end homes or businesses that can not easily handle the re-roof process like restaurants.
