The Top Five Roofing Issues in Bloomington and How to Prevent Them

Living in Bloomington, MN, means enjoying all four seasons, but your roof also has to weather them all. From frigid winters and snow-packed roofs to spring rainstorms and summer hail, the Twin Cities' climate can do a number on your home’s most important protective layer. No one understands what it takes to keep Minnesota roofs strong year-round like the pros at Signature Home Services. As a GAF Certified Plus Roofing Contractor, we install high-performance asphalt shingles, designer shingles, metal roofing, and flat roofing systems designed for the Midwest's unique weather conditions.

Let’s take a look at the top five roofing issues homeowners in Bloomington face, and how to prevent them before they become costly problems.

1. Ice Dams

The Problem:

Ice dams form when heat escapes into your attic, melting snow on the roof. That melted water runs down and refreezes at the colder edge of the roof, creating a dam that traps water behind it. This water can then seep under shingles and into your home, causing leaks, stains, and mold.

How to Prevent It:

• Upgrade your attic insulation—we use AttiCat® blown-in insulation, which fills gaps and helps retain heat inside your home.

• Ensure your attic is properly ventilated to maintain consistent roof temperatures.

• Install an ice and water shield membrane along vulnerable edges.

• After a major snowstorm, safely remove heavy snow buildup from the roof.

2. Roof Leaks and Water Damage

The Problem:

The heavy spring rains and winter thaw cycles we experience in Bloomington often lead to roof leaks. Water can infiltrate through cracked shingles, worn flashing, or poorly sealed roof penetrations. Left unchecked, this moisture can lead to interior ceiling damage, wall stains, and mold growth.

How to Prevent It:

• Have your roof inspected regularly, especially after storms.

• Replace missing or damaged shingles immediately.

• Keep gutters and downspouts clear so water can flow away from your roof and foundation.

3. Damaged or Missing Shingles

The Problem:

From hailstones to high winds, Bloomington’s weather is hard on shingles. Over time, shingles can crack, curl, or even blow off completely, leaving your home vulnerable to leaks and further damage.

How to Prevent It:

• Choose impact-resistant shingles, such as GAF designer shingles or metal roofing, for added durability.

• After each storm, check for visible signs of damage.

• Make sure your shingles are professionally installed to prevent premature failure.

4. Poor Roof Ventilation and Insulation

The Problem:

Without proper ventilation, heat and moisture can build up in the attic, causing damage to your roof from the inside out. You might notice ice dams, higher utility bills, or early shingle deterioration as a result.

How to Prevent It:

• Schedule a ventilation and insulation checkup with Signature Home Services.

• Install or upgrade attic insulation with AttiCat® blown-in insulation for full coverage.

• Ensure your soffit and ridge vents are working properly to promote airflow.

5. Structural Stress from Snow and Ice Loads

The Problem:

Minnesota snow is beautiful, but it’s also heavy. Accumulated snow and ice can add thousands of pounds of stress to your roof, especially if it’s older or has a flat design. Over time, this weight can cause sagging, leaks, or even structural failure.

How to Prevent It:

• After major storms, use a roof rake to safely remove heavy snow buildup.

• If your home has a flat or aging roof, consider reinforcing the structure.

• Get annual roof inspections to identify and address stress points before they become serious.
