Owning a home in Minnesota means your roof does far more than cap your house—it shields you through driving rains, heavy snow loads, ice dam risks, and long-lasting freeze/thaw cycles. The team at Holthaus Roofing draws on three decades of regional experience to help homeowners think about roof longevity, maintenance, and when replacement is truly necessary.
This post functions as a reference guide for Minnesota homeowners—covering key material choices, seasonal maintenance, signs you may need a new roof, and how to pick a roofing contractor wisely. We’ll include one internal link for deeper reading and one external resource for industry standards.
Why Minnesota roofs demand special care
Minnesota winters are unforgiving, and summer storms bring their own risks:
- Heavy snow and ice can overload your structure if drainage or roof slope isn’t optimal.
- Freeze/thaw cycles and ice dams can lead to water infiltration, attic damage, and structural issues.
- Summer hail and wind raise the risk of shingles losing granules, flashing failure, and early deterioration.
Holthaus Roofing emphasizes that “Minnesota homeowners face a climate that tests every element of a house—extreme cold, heavy snow, ice dams, summer storms and hail.”
Because of these demands, “routine repairs” may keep going for a time—but eventually, age, accumulated wear, or defective installation can trigger the need for full replacement. Their article “10 Signs It’s Time to Replace Your Roof in Minnesota” outlines key thresholds.
Choosing materials that perform here
Your materials matter almost as much as your installer. If a roof is poorly matched to the climate, you’ll pay sooner.
Asphalt architectural shingles
A common choice for Minnesota homes: they’re stylish, relatively affordable, and when properly installed can last 20–25 years. Holthaus recommends them as a standard for many homeowners.
Metal roofing
For longer-term durability and superior snow/shedding performance, metal roofs are a strong option—lasting up to ~50 years in good conditions. Holthaus notes this as a premium choice in Minnesota.
Flat/low-slope systems
For garages or additions with low slope, specialized systems like EPDM or TPO membranes may be required. Holthaus includes these in their service offerings.
Warranties & certified installation
Holthaus highlights that they’re certified installers (CertainTeed ShingleMaster and other brands) in order to deliver full manufacturer warranties and correct installation standards.
Seasonal maintenance: extend your roof’s life
To get the maximum lifespan from your roof, proactive maintenance matters. Here’s a breakdown per season:
| Season | Key Tasks |
|---|---|
| Spring | Inspect for hail or winter damage; clean gutters; check attic ventilation; remove debris and ice-dam remnants. |
| Summer | Monitor for storm impacts: lost shingles, flashing issues, granule loss in gutters; trim overhanging trees. |
| Fall | Remove leaves from roof, clear gutters, check attic insulation/venting to reduce winter ice-dam risk. |
| Winter | Safely clear heavy snow or ice buildup if access allows; monitor for attic condensation, leaks; ensure insulation/venting remains effective. |
Holthaus encourages homeowners to “clear debris promptly, clean gutters and downspouts, trim overhanging trees” as part of extending roof life.
Recognising when it’s time for replacement
Sometimes a roof can be repaired—but other times, replacement is the more cost-effective and safer path. Key signs include:
- Roof older than ~20 years (for standard asphalt shingles).
- Curling, cracking, or buckling shingles.
- Noticeable granule loss (in gutters or downspouts).
- Recurrent leaks or water stains in ceilings or attic.
- Visible light or daylight through the roof boards from the attic.
- Increased energy bills or uneven interior temperatures (indicating compromised insulation/venting).
Holthaus’ approach emphasises honest assessments: “If you don’t need it, we won’t try to sell it.”
Working with your roofing contractor—what to expect
Selecting the right contractor is just as important as the materials. Here are reference points to guide you:
Local expertise & climate awareness
You’ll want a contractor familiar with Minnesota’s specific roofing demands (snow loads, ice dams, freeze/thaw). Holthaus positions themselves accordingly.
Transparent assessment & honest advice
Good contractors will inspect thoroughly, explain what you truly need (not upsell), and offer clear guidance. Holthaus emphasizes this homeowner-first philosophy.
Written proposal & warranty information
Ensure your contract details materials, labor, clean-up, schedule, and warranty coverage. Ask about manufacturer warranties (especially for premium materials) and workmanship guarantees. Holthaus mentions certified warranties as part of their service.
Clean-up and site protection
Roof work involves debris, nails, potential damage to landscaping. A contractor should commit to magnetic nail sweep, debris removal, and protecting your property during work. Holthaus notes this as part of their process.
Insurance & licensing
Because roofs are major investments and bear significant risk (especially after storms), verify contractor licensing, insurance, and complaint history through your state’s portal.
