Get Ultimate Protection from Tough Minnesota Weather Conditions with GAF®, Part 2

Freezing temperatures, warm summers, strong winds, hailstorms, blizzards and tornadoes are all part of Minnesota’s variable weather. These factors create unfavorable conditions for your house, particularly your roof. To avoid costly repairs and replacements, Krech Exteriors, your roofing contractor in Minneapolis, recommends GAF® roofing system materials for your home.

With GAF’s high-quality shingles and accessories, you can avoid the following problems caused by exposure to extreme temperatures and severe weather conditions.


This type of damage can happen to asphalt shingles, and is caused by moisture trapped within the shingles. Once the shingles are exposed to the sun’s heat, the moisture will also heat up, resulting in blisters.

GAF shingles are sealed using Dura Grip™ adhesive. You can be confident that they will stay in place, reducing chances that moisture will accumulate in the shingles.


Your roof frequently faces strong winds. If your shingles can’t resist high wind, they may lift or blow off completely. When this happens, parts of your roof will be exposed to rain, snow and ice. Moisture can get through the roofing layers, causing leaks and damage to other parts of your roof.

With GAF shingles, you won’t have to worry about strong winds, because they have been tested to withstand wind speeds of up to 150 mph.

Curled Shingles

Aside from inadequate attic ventilation, there are other reasons shingles curl. When your roof is exposed to wet and dry cycles continuously, especially during winter, moisture can build up on the underside or bottom of the shingle. This may weaken the material, which can eventually lead to curling. Curled shingles may also indicate that your roof has reached the end of its service life.


Cracked shingles are most often caused by hail and other impact. GAF shingles have passed stringent impact tests, so you can be confident they will stand strong against severe weather.
