Spring Exterior Inspection Checklist: Catch Winter Damage Before It Gets Worse
Winter in Minnesota doesn't just test your furnace. It tests every square inch of your home's exterior — roof, siding, gutters, windows, and foundation. By March, that winter assault shows up as damage: ice dams, lifted shingles, rotting wood, split caulk, and moisture intrusion starting to work its way inside.
Spring inspection is when you catch these problems before they become $50K repairs. We've done this inspection on hundreds of homes across the Twin Cities. Here's the exact checklist we use — customized for Minnesota's harsh freeze-thaw cycles.
Why Spring Inspection Matters
Winter damage isn't always visible immediately. A lifted shingle might not leak for months. A failed caulk joint might not let water in until the next heavy rain. By May, when homeowners finally get around to checking, the damage has already spread inside the walls.
The cost difference:
- Catch a lifted shingle in March, repair it for $200
- Ignore it until July, discover rotting decking underneath, replace $5,000 of roof structure
That's why spring inspection is the most important 2 hours you'll spend on home maintenance.
What You'll Need
- Binoculars (see roof details from ground safely)
- Flashlight (check dark corners, attic)
- Ladder (if comfortable climbing; safer to skip this)
- Camera phone (take photos of issues)
- This checklist (printed or on your phone)
- Notepad (note dates, weather, observations)
Safety first: If you're not comfortable on a ladder, skip the roof. Call a professional. One mistake costs more than an inspection.
Roofing Inspection (Detailed)
From the Ground (with binoculars)
Shingles:
- [ ] Look for missing shingles (gaps in coverage)
- [ ] Check for lifted/curled shingles (edges peeling up)
- [ ] Note bald spots (granule loss = shingles wearing out)
- [ ] Look for moss or algae (usually north-facing, shaded areas)
- [ ] Check corners and edges (where wind damage appears first)
Flashing (where roof meets chimneys, vents, skylights):
- [ ] Flashing intact and not separated from roof
- [ ] Caulk around flashing not cracked or missing
- [ ] No daylight visible between flashing and roof
- [ ] Rust spots on metal flashing (especially older homes)
Gutters and downspouts:
- [ ] Gutters attached securely (not sagging away from house)
- [ ] Downspouts connected properly
- [ ] Debris from winter (ice dam breakdown, shingle granules, leaves)
- [ ] Standing water or puddles in gutter = poor slope
- [ ] Rust spots or visible holes in gutters
Ice dam damage (specific to Minnesota):
- [ ] Look for horizontal lines on roof = water backed up by ice dam
- [ ] Check fascia (trim at edge of roof) for soft/rotting wood
- [ ] Look for water stains on underside of soffit = moisture got inside
- [ ] Check gutters for ice dam debris (compacted ice chunks)
Interior roof check (from attic):
- [ ] Go into attic on a clear morning (daylight helps)
- [ ] Look for light leaks (holes, missing shingles will show daylight)
- [ ] Look for water stains on underside of roof deck (brown marks)
- [ ] Check insulation for wet spots or moisture (especially near roof edge)
- [ ] Smell for mold or musty odors (sign of hidden moisture)
- [ ] Check roof vents are clear and not blocked by ice/debris
Red flags that need immediate attention:
- 🚩 Visible holes or daylight through roof
- 🚩 Water stains on attic underside
- 🚩 Wet insulation
- 🚩 Soft/rotting fascia or trim
- 🚩 Mold or mildew smell in attic
Professional Thermal Inspection (Consider This)
If your roof is 15+ years old or you suspect ice dam moisture, get a drone thermal inspection ($2,500-3,500). Thermal imaging shows moisture trapped inside the membrane — invisible to the eye but will cause $100K+ in rot if ignored.
Siding Inspection
Exterior siding check:
- [ ] Walk entire perimeter (north, south, east, west sides)
- [ ] Look for cracks or splits in siding material
- [ ] Check for gaps or separation between siding panels
- [ ] Look for water stains or discoloration (indicates water intrusion)
- [ ] Check for soft/rotting wood (poke with screwdriver gently; shouldn't dent)
- [ ] Look for paint peeling or bubbling (sign of moisture behind siding)
Caulk and sealants:
- [ ] Around windows (where siding meets window frame)
- [ ] Around doors (especially patio doors)
- [ ] Corners where two walls meet
- [ ] Around trim boards (where they attach to siding)
- [ ] Any areas with visible gaps or missing caulk
Foundation and base:
- [ ] Check where siding meets foundation
- [ ] Look for gaps that could let rodents/water in
- [ ] Check basement/crawl space for water stains or moisture
- [ ] Look for efflorescence (white mineral deposits on foundation = moisture)
Red flags:
- 🚩 Open gaps between siding and foundation
- 🚩 Water stains inside basement/crawl space
- 🚩 Rotting wood at base of siding
- 🚩 Large sections of missing caulk
- 🚩 Mold or mildew on siding
Windows and Doors
Exterior seals and caulk:
- [ ] Walk around entire house, check every window
- [ ] Caulk around window frames intact (no gaps, cracks, or peeling)
- [ ] Same for exterior doors
- [ ] Look for missing or deteriorated weatherstripping
- [ ] Check for gaps between trim and siding
Window condition:
- [ ] Condensation between panes? (sign of failed seal, window needs replacement)
- [ ] Frost/ice buildup inside windows? (poor insulation or humidity problem)
- [ ] Visible damage to glass or frames
- [ ] Frames rotting or soft (especially wood or wood-composite)
Doors:
- [ ] Check threshold/sill for rot or gaps
- [ ] Weatherstripping intact and sealing properly
- [ ] Door closes smoothly without binding
- [ ] No gaps at top or sides (daylight shouldn't show)
Red flags:
- 🚩 Condensation between window panes (seal failed, replace window)
- 🚩 Rotting window frames
- 🚩 Large gaps around windows or doors
- 🚩 Daylight visible around closed doors
Drainage and Grading
Most water damage comes from water pooling against your house. Poor drainage is often the culprit.
Grading (ground slope):
- [ ] Walk around foundation perimeter
- [ ] Ground should slope DOWN and AWAY from house (6-8 inches drop in 10 feet)
- [ ] Look for low spots where water pools against house
- [ ] Check if landscaping has created barriers that block water flow
Gutters and downspouts:
- [ ] Downspouts discharge water at least 4-6 feet away from house
- [ ] Downspout doesn't point directly at foundation
- [ ] After rain, water flows away from house (not pooling)
- [ ] No water splashing back against foundation or siding
Basement/crawl space:
- [ ] Check after heavy rain (spring is rainy in Minnesota)
- [ ] Any water on floor or walls?
- [ ] Wet spots, efflorescence, or mineral deposits?
- [ ] Musty/moldy smell?
- [ ] Standing water in sump pump pit (normal) or everywhere (problem)?
Red flags:
- 🚩 Water pooling against house foundation
- 🚩 Water in basement after heavy rain
- 🚩 Efflorescence or staining on foundation walls
- 🚩 Downspouts discharging toward house or too close to foundation
- 🚩 Grading slopes TOWARD house (should be away)
Miscellaneous Checks
Exterior paint and trim:
- [ ] Paint peeling or cracking (especially wood trim)
- [ ] Gaps opening up in trim or trim separating from house
- [ ] Rot in fascia, soffit, or exposed wood
- [ ] Staining on paint (indicates water intrusion or mold)
Deck or porch (if applicable):
- [ ] Check framing underneath (look for rot, insect damage)
- [ ] Deck boards soft or spongy? (rot)
- [ ] Stairs stable and secure?
- [ ] Railings solid and up to code?
- [ ] Flashing where deck attaches to house intact?
Exterior vents and penetrations:
- [ ] Dryer vent clears properly (debris blocking it?)
- [ ] Range hood vent clear
- [ ] Any vents damaged or gaps around them
- [ ] Caulk around all penetrations (AC lines, electrical, plumbing)
Scoring Your Inspection
Use this simple system to prioritize repairs:
🔴 URGENT (fix within 2-4 weeks, before rain/heat arrives):
- Water intrusion signs (stains, wet insulation, mold)
- Open gaps or holes in exterior
- Rotting wood at structural points
- Failed flashing or sealants on roof
- Failed window seals or rotting frames
🟡 SOON (fix within 1-2 months):
- Lifted shingles or significant granule loss
- Cracks in siding or caulk (not yet leaking)
- Gutter issues (sagging, standing water)
- Paint peeling (cosmetic, but let water in if ignored)
- Weatherstripping in poor condition
🟢 LATER (monitor, fix within 6-12 months):
- Cosmetic issues (fading, minor cracks)
- Moss or algae (clean first, monitor)
- Minor paint wear
- Gutters need cleaning
The Professional Report
If you find any 🔴 URGENT items, call a contractor immediately. Bring this checklist to your inspection call — it shows you've already done homework, makes the contractor's job easier, and helps them prioritize.
What to tell your contractor:
- "I found [specific issue] in [location]. Is this urgent?"
- "Should I get a professional inspection before proceeding?"
- "What's the worst-case scenario if I ignore this?"
- "What's the repair timeline and cost estimate?"
A good contractor will respect that you've done due diligence. They'll explain priorities clearly and give you options (repair now, monitor, can wait).
After the Inspection
Document everything:
- [ ] Take photos of any issues (date stamped)
- [ ] Write dates and weather conditions
- [ ] Note which areas you checked
- [ ] Create a "repairs needed" list (urgent, soon, later)
Schedule follow-ups:
- [ ] Fix urgent items immediately
- [ ] Schedule contractor estimates for 🟡 SOON items
- [ ] Plan fall inspection to catch new issues (rotate the checklist)
For your records:
- [ ] Keep photos dated and organized (phone backup)
- [ ] Keep contractor estimates and warranty documents
- [ ] Track what repairs you've done and when
- [ ] This becomes your home's maintenance history (helps resale value)
When to Call a Professional
Don't DIY if you find:
- 🚩 Water stains inside attic or home (call immediately)
- 🚩 Rotting wood at structural points (foundation, fascia, roof deck)
- 🚩 Mold or mildew (needs moisture assessment)
- 🚩 Extensive roof damage (not 1-2 shingles, but multiple areas)
- 🚩 Anything you're unsure about (better to ask than guess)
What to ask contractors:
- "Can you do a thermal inspection to check for moisture?"
- "Is this damage from winter or pre-existing?"
- "What's your recommended timeline?"
- "What warranty do you provide (material + labor)?"
- "Do you have references from other homes in this area?"
