Common Home Inspection Issues in Florida Homes

If you bought a home in Chicago, New York, or California, you probably walked through a general home inspection that flagged a cracked caulk line around a tub, an aging water heater, and a few outlets without GFCI protection. That experience is real — and largely useless preparation for buying in Central Florida. Florida's climate produces a different set of failure modes: persistent heat and humidity, an active hurricane window, year-round pest pressure, and soil conditions that don't exist in most of the country. The inspection findings that matter here are not the same ones that mattered there. Here's what shows up repeatedly in Orange County inspections and what buyers need to understand before they respond to a report.

Roofs: The Single Most Common Deal Issue in Orlando

Ask any Orlando real estate attorney or title company what kills more contracts than anything else, and roofs will be near the top of every list. A standard asphalt shingle roof carries a 15–20 year rated life. Florida's UV intensity and storm exposure push real-world performance to the low end of that range or below it. What makes this a financial issue, not just a repair issue, is insurance: many Florida insurers will not write a new homeowner policy on a roof older than 15 years. Some carriers set the threshold at 10. If you're financing the home, you need insurance to close. No insurance, no loan.

Inspectors flag granule loss (shingles shedding their coating, leaving bare asphalt exposed to UV), improper or deteriorated flashing at roof penetrations and valleys, soft spots indicating damaged decking underneath, and failed pipe boots — the rubber collars around plumbing vents that are among the most common sources of slow interior leaks in Florida homes. Tile roofs, standard on most newer construction in Dr. Phillips, Windermere, and Lake Nona, last significantly longer but break when trees or debris hit them in a storm. A handful of cracked tiles is a repair, not a crisis; extensive field tile damage is a different conversation.

If the general inspector flags anything about the roof — and most will caveat their roof observations with "further evaluation recommended" — get a licensed roofing contractor up there before you respond to the inspection report. General home inspectors in Florida are not licensed roofers. Their opinion that a roof looks aged is not a repair estimate. A roofer's opinion costs $150–$300 and gives you an actual number to negotiate from.

HVAC: High Use, High Wear, High Stakes

A 15-year-old HVAC unit in Minnesota might have 10–12 real cooling seasons behind it. The same unit in Orlando has been running essentially nonstop since it was installed. Florida's cooling load is not seasonal — it's a year-round baseline with a brutal June-through-September peak. Systems age faster here than the nameplate ratings suggest.

Inspectors note the age of the unit, condition of the air handler and coil, refrigerant line insulation, and drain line condition — a clogged condensate drain is among the most reliable sources of water damage in Florida homes, and it costs almost nothing to prevent with routine service. They also note ductwork condition: flex duct, used in most homes built after 1980, deteriorates over time and can collapse or develop gaps at connections. Older homes sometimes have metal duct systems that can develop mold internally without obvious visible signs.

An undersized or poorly commissioned HVAC system creates moisture problems regardless of how new it is. If the unit can't keep indoor humidity below 60%, you'll have mold growth on surfaces, in closets, and inside walls whether or not the unit is cooling the air temperature adequately. Any HVAC over 12–15 years old should factor into your offer or your negotiation response. Replacement of a central system in Central Florida runs $6,000–$12,000 installed, depending on size and system type.

Water Intrusion and Mold

Moisture is the dominant long-term threat to Florida homes, and it enters through more routes than most buyers expect. Roofs account for some of it, but the more common sources in established neighborhoods are windows and sliding glass doors — particularly in homes built between the early 1980s and early 2000s, where weatherstripping and glazing sealants have often failed without any exterior signs of damage. Poor grading around the foundation is another: if the soil slopes toward the slab rather than away from it, you're directing every rain event at the perimeter of the house. Bathroom tile grout failure creates hidden moisture behind walls. The HVAC condensate drain, mentioned above, creates water damage near the air handler when it overflows.

Mold is not always visible. A musty smell in a bedroom with no water staining on the ceiling is a real finding, not imagination — and it warrants a separate mold assessment ($300–$500 from a qualified inspector, using air sampling) before you proceed. Contained mold remediation in a single room or small area typically runs $1,500–$3,500. Whole-house situations can reach $8,000 or more before you've addressed the water source that caused it.

Wood-Destroying Organisms: A Separate Licensed Inspection

This one surprises most buyers from out of state. The general home inspector does not inspect for termites or wood-destroying organisms in Florida. That is a separate licensed inspection, performed by an inspector licensed by the Florida Department of Agriculture and Consumer Services (FDACS). WDO inspections cost $65–$150 and should be ordered as a matter of course on every resale home in Orange County.

Both subterranean and drywood termites are active in Central Florida. Subterranean termites live in the soil and build mud tubes to reach wood; treatment involves soil treatment or bait stations and runs $500–$1,200. Drywood termites live inside wood members and require fumigation if the infestation is distributed throughout the structure — tent fumigation for a house in the 2,000–3,000 square foot range runs $1,500–$4,500. Florida sellers are required to disclose known WDO history, but disclosure requirements only cover what a seller actually knew. An active infestation in an attic the seller hasn't entered in three years is not unusual.

Electrical: Know the Vintage of the Home

Homes built in the 1960s through 1980s in established Orlando neighborhoods — College Park, SODO, Winter Park, Maitland, Delaney Park — are more likely to have electrical systems that create insurance problems or represent actual hazards. The two most common findings:

Federal Pacific and Zinsco panels are known fire hazards, documented in CPSC reports. Most Florida insurers will not write a new homeowner policy on a home with one of these panels in place. Replacement runs $2,000–$3,500. If you're buying a home with either panel, get that cost into the negotiation or price it into your offer.

Aluminum wiring in branch circuits (not service entry, which is fine — circuit wiring) was used in homes built roughly 1965–1973 when copper prices spiked. Aluminum wiring expands and contracts more than copper, loosens at connections, and is a fire risk at outlets and switches. Remediation involves either full rewiring or pigtailing at every connection point with approved connectors; whole-house cost runs $2,000–$5,000 depending on size and method.

Also common in inspections of older homes: double-tapped breakers (two circuits on one breaker terminal), open ground outlets, and reversed polarity — all fixable, all worth noting.

Plumbing: Know the Pipe Material

Three pipe materials show up in Florida resale homes that create either insurance or reliability problems:

Polybutylene (PB pipe) — gray plastic pipe used between roughly 1978 and 1995. PB reacts with chlorinated water over time and fails at fittings, often without warning. Insurers increasingly surcharge or decline homes with active PB plumbing. Repiping runs $5,000–$12,000 depending on home size.

Galvanized steel — used in homes built before about 1960. The pipe corrodes internally, restricting flow and eventually developing pinhole leaks. If your inspection notes galvanized supply lines, start budgeting for repipe.

Cast iron drain lines — used in homes built roughly through the 1980s. Cast iron under a slab eventually corrodes from the inside, leading to collapsed sections or chronic leaks beneath the foundation. If the inspector can't verify drain condition (common — they're buried), request a camera inspection of the sewer lateral. It costs $200–$400 and can save you from discovering a $15,000 slab plumbing repair six months after closing.

Sinkhole Indicators

Orange County sits in a moderate sinkhole risk zone; Hillsborough and Pasco counties to the west are rated higher. Home inspectors are not qualified to identify sinkholes, but they flag structural indicators that warrant geotechnical evaluation: stair-step cracking in concrete block walls, diagonal cracks at corners of door and window openings, doors or windows that have shifted out of square and won't close properly, or visible depressions in the yard. None of these individually is a definitive sinkhole indicator — settlement, expansive soil, and foundation issues can produce similar symptoms — but they all warrant further investigation before you close. A sinkhole investigation from a licensed professional geologist runs $1,500–$3,500.

Sinkhole coverage is separate from standard homeowner insurance in Florida and must be added as an endorsement or carried as a separate policy.

What the General Inspection Actually Covers

Florida home inspectors are licensed by the Department of Business and Professional Regulation (DBPR) and follow published standards of practice from InterNACHI or ASHI. They inspect visible and accessible systems: structural components, roofing (from grade or from a ladder, depending on pitch and conditions), electrical, plumbing, HVAC, and interior. They do not open walls, camera drains, test for mold, or make structural diagnoses. Their job is to document observed conditions — not to tell you the house is safe or to quantify repair costs.

Think of the general inspection as triage. It identifies the systems that need a closer look. From there, you bring in specialists: a roofer for roof concerns, an HVAC contractor for aging equipment, a WDO inspector as a matter of course, a plumber with a drain camera for older homes, and a geologist if the inspector notes cracking patterns consistent with soil movement. The general inspection costs $350–$600 for a typical single-family home in the Orlando area. Specialty inspections add another $200–$600 depending on what you need. That total, relative to the cost of buying a problem you didn't know about, is the most defensible money you'll spend in the transaction.
