Fall Exterior Inspections You Can Do as a Homeowner

As summer warmth fades and crisp fall air takes its place, now is the perfect time to tackle exterior inspections around your home. A proactive inspection helps you catch small issues before winter’s harsher weather turns them into costly repairs. At Marroquin Exteriors, we believe in empowering homeowners with simple, effective checks you can do yourself — and knowing when it’s best to call professionals.

Below are seven essential fall exterior inspections every homeowner in Central Pennsylvania (Carlisle, Harrisburg, Hershey, Camp Hill, Mechanicsburg and beyond) should perform — especially if your home has asphalt roofing, vinyl siding, gutters, decks, windows/doors, or fencing (all areas we specialize in).

  1. Roof and Shingle Condition

    Your roof is your home’s first line of defense. In fall, check:

    • Missing, cracked, or curling shingles — These may signal wear or damage from summer storms.
    • Granule loss in gutters or downspouts — Excess granules may mean your shingles are nearing the end of their life.
    • Flashing and sealants — Around chimneys, vents, skylights, and dormers, check for gaps or cracks in the flashing or sealant.
    • Roof valleys and ridges — Inspect these critical joints for signs of weakness or deterioration.

    If you spot major damage, leaks, or structural sagging, contact a certified roofing contractor like Marroquin Exteriors for a professional inspection and free estimate. We serve homeowners with all of their roofing concerns throughout Central PA.

  2. Gutters, Downspouts & Debris

    Clogged or damaged gutters cause water backup, ice dams, and siding damage. In fall:

    • Clean out leaves, seed pods, grit, and debris
    • Check for sagging or loose sections — Ensure gutters are securely attached to fascia.
    • Inspect seams and joints for leaks or separation
    • Downspouts – Verify they direct water at least 3–4 feet away from your foundation
    • Look for signs of overflow or staining on siding

    At Marroquin Exteriors, we offer free gutter cleaning with every roof job, but homeowners can also perform basic maintenance to extend gutter life.

  3. Siding & Exterior Walls

    Vinyl siding, fiber cement, or other exterior walls need attention before winter:

    • Loose, cracked, or warping siding panels — Gaps let moisture and pests in
    • Sealant and caulking — Around windows, doors, corners, and trim, look for cracks or deterioration
    • Stucco or masonry — Check for hairline cracks or crumbling mortar
    • Signs of water stains or mold — These may indicate leaks behind the siding

    Prompt repairs help preserve insulation and prevent water infiltration during freezing temperatures.

  4. Windows & Doors Seals

    Your windows and doors are vulnerable points for drafts and leaks. In fall:

    • Inspect weatherstripping and gaskets — Replace any that are dry, cracked, or missing
    • Check caulk lines — Look around frames for gaps needing resealing
    • Inspect sash operation — Windows and doors should open and close smoothly
    • Glass panes and frames — Check for moisture between double panes and check for frame rot

    Well-sealed windows and doors improve energy efficiency and reduce strain on HVAC systems through the colder months.

  5. Decks & Porches

    Your deck may have taken a beating through summer storms and UV exposure. Prior to winter:

    • Inspect boards, railings, and posts — Look for splits, rot, or insect damage
    • Check fasteners — Nails, screws, and brackets may loosen or corrode
    • Flush-clean and seal — Clean surface grime and apply protective sealant if needed
    • Drainage and grading — Make sure water drains away from the deck structure

    A well-maintained deck keeps your outdoor living space safe and prolongs its lifespan.

  6. Chimneys, Vents & Penetrations

    Every roof penetration is a potential leak point. In fall:

    • Chimney flashing & crown — Inspect for gaps, cracks, or deteriorated mortar
    • Roof vents, plumbing stacks, exhaust fans — Make sure sealants and boots are intact
    • Skylights and dormers — Check for flashing damage and seal degradation

    If you see gaps, cracks, or signs of water stains under these features, schedule a more detailed inspection.

  7. Foundation, Grading & Drainage

    Finally, inspect at ground level:

    • Foundation walls — Look for cracks, spalling, or signs of moisture intrusion
    • Grading slope — The soil should slope away from your foundation (¼ inch per foot is a good rule of thumb)
    • Downspout extensions & splash blocks — Ensure runoff is guided away
    • Basement or crawl space vents — Clear obstructions and check for signs of moisture

    Proper drainage today prevents frost heave, foundation damage, and basement leaks tomorrow. Basement and foundation issues can lead to structural and roof issues down the road.

Checklist: What to Record During Your Inspection

  • Take photos of any issues or changes
  • Use a notebook or smartphone to log: location, problem type, severity
  • Compare with last year’s inspection notes (if available)
  • Prioritize safety: use stable ladders, wear slip-resistant shoes, and don’t attempt steep roof work alone- that’s what we’re here for
