A safe 15-minute fall walkthrough
- From the ground, look for sagging gutters, visible debris, loose downspouts, and water marks below the eaves.
- During the next rain, note overflow, water pooling beside the foundation, or a downspout discharging too close to the wall.
- From inside, check whether the attic hatch closes snugly and look for ceiling or attic-access staining without stepping onto an unsafe surface.
- Write down roof, drainage, or insulation questions for a qualified roofer or weatherization professional instead of climbing to investigate.
1. After the leaves start falling: trace the water
Make the first pass from the ground, then observe the next rainfall. The University of Minnesota Extension's basement-moisture guidance recommends checking gutters, downspouts, and surface grading early when rainwater is getting near a foundation.
Watch the roof edge and each outlet
- From a safe spot on the ground, scan for gutters that sag, pull away, or have plants and leaf buildup visible from below.
- During rain, look for water spilling over the gutter, leaking at a seam, or running behind the gutter rather than into it.
- Check that downspouts are connected and that their ground-level outlets are not blocked by leaves, soil, or stored items.
- Notice whether water is pooling by the wall, washing out a planting bed, or leaving damp marks inside the basement after storms.
- Arrange gutter cleaning or repairs when the work requires roof access, ladder use at height, or reaching near overhead wires.
Extension recommends directing downspout discharge at least four feet beyond the wall and grading soil away from the foundation. Its measurements are guidance to discuss for your site, not a substitute for local drainage rules, lot constraints, or a professional assessment.
2. Before the first snowfall: look for heat escaping upward
Ice dams form when parts of a snow-covered roof stay above freezing while the eaves remain below freezing. The University of Minnesota Extension explains that heat escaping from the house—often through air leaks at the ceiling—is a major contributor. Water that backs up behind an ice ridge can enter the roof and damage ceilings, walls, insulation, and finishes.
Make observations from safe access points
- Check that the attic hatch closes and latches; note a visible gap or missing insulation around the hatch for follow-up.
- From the room below, note recessed lights, plumbing or wiring openings, and ceiling cracks that may need an air-leak assessment.
- If the attic has a clearly safe, stable walkway, look only from that walkway for damp insulation, staining, or visible air-leak pathways. Do not step onto ceiling drywall or move insulation around wiring, chimneys, or hot equipment.
- Ask a qualified weatherization professional to assess air leakage; Extension says a blower-door test and infrared camera can help locate heat loss.
- Address ceiling air leaks before deciding whether to add insulation. Ask a professional to check ventilation and combustion-appliance air needs when tightening the home.
A powered attic fan is not a shortcut: University of Minnesota Extension does not recommend mechanical attic ventilation as an ice-dam fix in Minnesota because it can create other attic-moisture problems and negative pressure.
3. Set the roof-work boundary before a problem appears
Extension warns that roof work can injure people and damage a home, and advises contacting professionals. OSHA's roof-fall prevention material is written for work crews, but it underlines the planning, training, and protective equipment involved in working at height.
Good homeowner jobs: observe, document, schedule
- Photograph visible gutter or roof-edge concerns from the ground and note where water lands during rain.
- Keep downspout outlets clear at ground level and make sure extensions stay in place after mowing or landscaping.
- Record leaks, stains, and dates in your home file so a roofer or weatherization contractor has a useful starting point.
Call a qualified professional for work at height or in the roof system
- Use a qualified gutter or roofing contractor for roof access, loose or missing shingles, flashing, roof penetrations, or repairs.
- Use a weatherization or insulation professional for air sealing, insulation changes, or work near wiring, chimneys, ducts, and combustion equipment.
- Do not climb onto the roof, lean out from an upper window, or improvise a ladder setup to inspect or clear a gutter.
Keep the fall check connected to the rest of year one
