Types of Asphalt Roof Shingles

Three-Tab Shingles

When choosing your shingles, there are several things to consider including your budget. Three-tab are a traditional option, and are still the most economical shingle today. 3-Tab shingles are available in a wide variety of colors and include limited 20-25 year warranties.

Architectural Shingles

Architectural asphalt shingles, one of the most popular styles, contain no cutouts, but their lower portions are laminated with an additional asphalt layer. This creates the contoured, dimensional look that gives them their name. Asphalt sealant bonds the layers, reinforcing the shingles’ waterproof capability. Architectural shingles are nearly twice as thick as three-tab shingles and are therefore more durable and less vulnerable to curling. Weight and wind resistant as well as algae resistant. The 10-year algae resistance comes from the small granules of zinc that are added to the shingles. Three-tab shingles usually weigh 205 lbs. per square and are rated for wind speeds up to 60 mph; architectural shingles weigh 240 lbs. per square and are rated for wind speeds up to 120 mph.

Specialty Shingles

Designer Shingles

Designer Shingles provide a wide variety of options that emulate the rich look or natural materials, like slate and wood, while providing your home with an architecturally stylish, dimensional look.

Flat Roofs

The experienced team at Minnesota Home Improvements also handles light commercial and residential flat EPDM rubber roofing projects. EPDM provides immediate and long-term roofing solutions for flat or low slope roofs. EPDM consists mainly of oil-based by-products with some modifiers and stabilizers added to extend its service life.

Types of materials commonly used:


The boards or sheet materials fastened to the roof rafters to cover the house.


The technology of new synthetic felts allows decking to breath better. This is especially critical in vaulted areas and older homes with intake ventilation issues. There are three types of underlayment: synthetic underlayment, asphalt felt and ice and water shield. When choosing underlayment, the goal is to provide the best protection against leaks with quality material that fall within your budget. A high quality synthetic underlayment can extend the life of your roof by an average of 5 to 10 years. With the amount of snow and ice our geographic area receives, it is a wise investment to install an ice shield in combination with synthetic underlayment where appropriate.


Tar or asphalt saturated paper made with some fiberglass. It is the most widely used and the most affordable roofing underlayment. While felt offers a general level of protection against leaks, it may not be enough if you live in an area that gets heavy snow and/or rainfall.

Ice & Water Shield

A thick asphalt or bitumen based reinforced membrane. This membrane has a sticky surface that glues to the roof deck, and does not tear after installation. It protects the roof from water penetration caused by wind-driven rain and ice dams. It is essential to use an ice shield in critical areas such as eaves, rakes, ridges, valleys, dormers and skylights.


High quality underlayment and higher investment than felt underlayment. It has a number of advantages such as a longer lifetime, more tear proof, and usually does not deteriorate.


The features of the roof’s design such as slope, shape, layout, etc., that determine its ability to shed water.


Sheet metal laid into the various joists and valleys of a roof system to prevent water leaks.

Drip Edge

A roof flashing that is installed at the leading edge of your shingle near the gutter. It is a piece of metal flashing slipped under the roofing material and over the top of the paper felting underneath the roofing shingles that hangs down into the gutter approximately 1”. The primary objective of this drip edge is to keep the rain-water from soaking up under the roofing shingles and causing dry rot of the plywood under the felt paper. It also diverts water into the gutter instead of going behind the gutter, which could also dry rot of the wood behind the gutter. This can cause the gutter to come loose and even make it pull away from the fascia board or rafter tails.

Chimney Flashing

Because leaks can occur at the chimney, flashing called Chimney Flashing prevents water from entering at the point where the chimney and the roof meet. Every chimney is different, so installing chimney flashing is often a custom project. Other times that the chimney flashing will need to be replaced include when it is missing, when it is rusted through, when it is totally covered with roofing tar, or when the shingles are going to be replaced.

Pipe Flashing

Installed as a water-tight seal around plumbing vent pipes or outside wall penetrations as a prevention against leaks. These come in a variety of materials and can be chosen to best match the exterior of your home.

Roof covering

Shingles, shakes, steel, etc., that protect the decking from weather. This is the first layer of protection for your roof decking.


Attic ventilation is key to the longevity of your roof. Both proper intake and exhaust ventilation are needed. Improper roof ventilation may void your manufacturer’s warranty. In addition, proper ventilation of bath and kitchen fans is need to ensure ice damming and attic damage does not occur.
