In Pullman, the window between the end of fall and the start of serious lake effect snow season is short. By mid-November, roofs in Allegan County can be under inches of wet, heavy accumulation with no opportunity for safe inspection or repair until March. A thorough roof inspection completed in September or October — before temperatures drop and before the first wet snow — is one of the most cost-effective maintenance decisions a Pullman homeowner can make. This checklist walks through what to look for and what to prioritize.
Why Timing Matters Specifically in Pullman
Pullman’s position in Allegan County’s lake effect snow corridor means the transition from “fine” to “problematic” for a marginal roof can happen in a single weather event. A roof with slightly compromised flashing, marginal shingle granule coverage, or inadequate ice and water shielding at the eaves will survive a dry winter. It will not survive a 14-inch lake effect event followed by a 40°F day and a subsequent hard freeze — the freeze-thaw sequence that turns minor vulnerabilities into active leaks.
The practical target: complete your inspection by October 15th. That leaves time to schedule and complete any identified roof repairs before the late October / early November period when lake effect season typically begins in earnest in West Michigan.
Exterior Inspection Checklist
Start from the ground with binoculars before considering going onto the roof. A significant amount of diagnostic information is visible from ground level:
Shingle Condition
- Missing or displaced shingles: Visible gaps in the shingle field, especially near ridges and hips where wind uplift is greatest.
- Curling or cupping: Shingle edges that lift upward (curling) or shingle centers that sink while edges rise (cupping) indicate end-of-life or moisture-related degradation. Either condition creates vulnerabilities when snow accumulates and then refreezes.
- Granule loss: A uniform mat appearance without visible granule depth. You can also check your gutters — granule accumulation in gutters after a rain event indicates active shingle degradation.
- Cracking or brittleness: Visible on older shingles during a close-up inspection. Brittle shingles are particularly vulnerable to impact damage from ice and hail.
Flashing Inspection
- Chimney flashing: Look for separation between the flashing and the chimney masonry, rust staining on the metal, or visible gaps where the step flashing meets the shingle field.
- Pipe boots: The rubber gaskets around plumbing vent pipes degrade in UV and cold. Cracked or separated pipe boot collars are a common source of small, slow leaks that become problematic under snow load.
- Valley flashing: In the V-intersections where two roof planes meet. Open valleys (exposed metal) should show no rust or gaps. Closed valleys (shingles overlapped) should show no lifted or open edges.
- Skylight flashing: If your home has skylights, inspect the perimeter flashing carefully. Skylight flashing is one of the most common ice-dam failure points on Pullman area homes.
Ridge and Hip Inspection
- Ridge cap shingles should lie flat with no lifted edges. Wind uplift on ridge caps during a lake effect storm with 50+ mph gusts can pop fasteners on marginal installations.
- If you have a ridge vent, confirm the vent openings are not obstructed by shingle material, debris, or wasp nests (common in rural areas like the farmland subdivisions surrounding Pullman).
Gutter and Downspout Condition
- Gutters should be clear of debris before winter. Leaf and debris accumulation in gutters accelerates ice dam formation by blocking the drainage path for snowmelt.
- Check gutter hangers and fascia attachment. A gutter that separates from the fascia under snow and ice weight can pull fascia boards and create additional vulnerabilities.
- Downspouts should extend at least 6 feet from the foundation. Pooling at the foundation during snowmelt creates basement moisture and potential structural issues over time.
Attic Inspection Checklist
The attic is where many of the conditions that drive winter roofing problems originate. Inadequate insulation and ventilation are the primary causes of ice dams — more so than the roofing material itself. An attic inspection in October can identify correctable conditions before they become a winter emergency.
- Ventilation balance: Adequate airflow from soffit vents to ridge vent keeps the attic cold in winter, which prevents uneven snowmelt on the roof surface. Blocked soffit vents (often from blown insulation) are the most common ventilation failure in older Michigan homes.
- Insulation depth and coverage: R-49 to R-60 is the recommended range for Allegan County’s climate zone. Thin or uneven insulation allows heat loss that drives the freeze-thaw cycle responsible for ice dams.
- Signs of existing moisture: Staining on the decking, insulation that feels damp or shows mold growth, or frost on the decking surface (visible on a cold fall morning) all indicate existing infiltration that needs to be identified and resolved before winter.
- Bathroom and kitchen exhaust paths: Verify that bathroom fans and kitchen range exhausts vent to the exterior — not into the attic space. Venting moisture into the attic is a direct cause of sheathing rot and mold that is not visible until it becomes severe.
When to Call a Professional vs. Handle It Yourself
Ground-level inspection and attic inspection are DIY-accessible for most Pullman homeowners. Actual roof access for close-up inspection should be approached with caution — roofs with any pitch steeper than 4:12 become significantly more hazardous without proper fall protection, and older roofing materials can be more slippery than they appear.
If your ground-level and attic inspections identify any of the following, schedule a professional assessment before winter:
- Multiple missing or visibly displaced shingles
- Any evidence of flashing separation or gaps at penetrations
- Roof age over 15 years without a recent professional assessment
- Any evidence of previous leaks, water staining in the attic, or soft spots in the decking
- Ice dam damage from the previous winter that was not formally repaired
Our professional roof inspection service covers all the items in this checklist plus close-up flashing and fastener assessment that requires safe roof access. We serve Pullman and the surrounding Allegan County townships and can typically schedule fall inspection appointments within 1-2 weeks in September and October.
Finding Us from the Pullman Tavern
If you are in the village center near the Pullman Tavern on M-40 and need to stop by our office, we are just a few minutes south. From the Tavern, head south along M-40 to 56th Street, then turn west. Our office at 605 56th Street is on the right as you move into the rural residential stretch. Consultations for fall inspection scheduling are welcome by appointment — just give us a call at (616) 360-2522 to set a time before the season gets away from us both.
The Fall Inspection as Insurance
A pre-winter roof inspection is not a guarantee that nothing will go wrong in a lake effect snow season. What it is: a reliable way to eliminate the preventable failures and catch the developing problems before they become winter emergencies. The cost of an inspection is a small fraction of the cost of emergency repair in February or the water damage remediation that follows an undetected infiltration through a winter of heavy snow cycles.
Pullman’s climate does not give roofs much margin. An October inspection does.
