Minnesota winter places heavy demands on a roofing system. Snow, ice, freezing temperatures, wind, and repeated thawing can expose problems that seemed minor during summer.
September is a good time to evaluate your roof because there is still time to complete repairs before the first lasting snowfall.
You do not need to wait for a leak to find out whether the roof is struggling. Start by asking these seven questions.
1. Are Any Shingles Missing, Cracked, or Curled?
Shingles form the outer layer of protection against rain, snow, and wind. When they are missing or damaged, moisture can reach the materials underneath.
Look from the ground for:
- Empty spots
- Raised edges
- Cracked tabs
- Curled corners
- Uneven roof lines
- Shingle pieces in the yard
Older shingles may also lose granules, leaving dark or smooth-looking patches.
One damaged area may be repairable. Widespread deterioration may indicate that the roof is nearing replacement. Keystone’s roof repair services can help determine the difference.
2. Has the Roof Leaked During Rain?
A roof that leaks during fall rain may also leak when snow melts.
Think back over the summer. Did you notice:
- Ceiling stains
- Damp attic insulation
- Water near a chimney
- Peeling paint
- Musty odors
- Moisture around vents
- Dripping during wind-driven rain
Do not assume a stain is old without investigating it. Moisture can appear, dry, and return during the next storm.
Keystone’s resource on common leaking-roof signs can help you identify symptoms that deserve attention.
3. Are the Gutters Ready for Leaves and Snowmelt?
Gutters move water away from the roof edge, siding, and foundation. When they are clogged or damaged, water can overflow and freeze near the roofline.
Before leaves begin falling heavily, check for:
- Existing debris
- Sagging sections
- Loose brackets
- Poor drainage
- Dented downspouts
- Water near the foundation
- Granules collecting in the gutter
Clean the system safely and confirm that downspouts carry water away from the home.

4. Is the Attic Properly Ventilated and Insulated?
Winter roofing problems are not always caused by the outside weather alone.
Warm air from the living space can enter the attic and heat the underside of the roof. Snow may melt higher on the roof and refreeze near the colder edge, contributing to ice dams.
Poor insulation and ventilation can also create condensation, moisture damage, and uneven indoor temperatures.
Possible warning signs include:
- An unusually warm attic
- Damp insulation
- Frost on attic surfaces
- Rusted nails
- Musty odors
- High heating or cooling costs
- Past ice dams
Keystone’s attic insulation services can be considered when improving the home’s thermal performance and reducing heat loss.
5. Is the Flashing Secure?
Flashing protects vulnerable roof transitions, including areas around:
- Chimneys
- Plumbing vents
- Skylights
- Sidewalls
- Roof valleys
- Dormers
Loose, bent, rusted, or separated flashing may allow water beneath the roofing material.
Because these areas can be difficult to inspect from the ground, professional evaluation is often the safest choice.
6. Has the Roof Been Through a Recent Hail or Windstorm?
Storm damage does not always cause an immediate leak.
Hail may bruise shingles or remove granules. Wind may loosen seals or crease shingles that settle back into place. These weak spots may become more noticeable during winter wind, snow, and ice.
If strong storms moved through your neighborhood during spring or summer, a storm damage inspection may provide useful information before winter.
Take note of any dents on gutters, downspouts, vents, or siding. They may indicate that the roof also received impact.
7. How Old Is the Roofing System?
Age alone does not determine whether a roof needs replacement. Installation quality, ventilation, material type, storm history, and maintenance all matter.
Still, older roofs deserve closer attention before winter.
Ask yourself:
- Do you know when the roof was installed?
- Have repairs become more frequent?
- Are several roof sections showing wear?
- Has the roof leaked more than once?
- Are shingles cracking or shedding granules?
- Has a contractor previously recommended replacement?
If you are unsure about the roof’s age, previous permits, seller records, receipts, and inspection reports may provide clues.
Keystone’s guide to the average roof lifespan in Minneapolis explains several factors that affect how long a roof may last.
What a Fall Roof Inspection Should Accomplish
A roof inspection should do more than produce a list of problems. It should help you understand:
- What is working correctly
- Which areas need maintenance
- Whether repairs are urgent
- How much useful life may remain
- Whether ventilation or insulation is contributing to problems
- Which projects should be completed before winter
- Which projects can be planned for later
Clear recommendations allow you to make decisions without feeling pressured or overwhelmed.
