Selling A Gulf Coast House? Inspectors Flag Roof And Drainage Issues
When you sell, a home inspector will perform a non-invasive visual check of the major systems, including the roof, foundation and exterior, structure, HVAC, plumbing, electrical, and safety equipment, to identify material defects and safety hazards that affect the sale. Inspectors document what they find in a prioritized report so buyers and agents can see what matters most. Sellers who get ahead of these checks, gather maintenance records, and consider targeted pre-listing tests tend to move through negotiations with far fewer surprises.
TL;DR:
For homes more than 20 years old, consider a sewer scope before listing; standard inspections cannot see buried lines, and backups can disrupt closing.
Test for radon before listing; the EPA advises mitigation at 4 pCi/L, while suspected mold, lead, or asbestos needs specialist testing.
There is no pass or fail score: reports prioritize safety and major defects, while cosmetic wear and routine maintenance usually call for disclosure or upkeep.
Before the inspection, clear access to the attic, electrical panel, and water heater, test outlets, and gather repair receipts, permits, and maintenance records.
Exterior and Foundation: Grading, Siding, Windows, Doors, Drainage
The exterior and foundation often set the tone for the rest of a buyer’s confidence in the home, so inspectors spend real time here. They look at foundation walls for cracks, noting the orientation and width, since horizontal or widening cracks suggest settling or structural movement that a vertical hairline crack usually does not.
Drainage gets just as much attention. Inspectors check whether the ground slopes away from the foundation, whether gutters and downspouts move water away from the house, and whether there is evidence of chronic water intrusion like staining or soft soil near the base of walls.
On siding and trim, they check for:
Cracked, warped, or missing siding and deteriorated exterior paint
Windows and doors that operate smoothly with intact flashing and weatherstripping
Visible pest activity or wood rot near ground contact points
Standing water, erosion, or poor drainage patterns around the foundation
Following the Home Inspection Standards of Practice, inspections remain visual and non-invasive, so an inspector who notices a pattern like a sloped floor or a stair-step crack in masonry will often recommend a specialist evaluation rather than guess at the cause.
Pro Tip: If you already know about a foundation crack or drainage issue, get a contractor’s opinion before listing. A documented, minor explanation often reassures buyers more than silence does.
Roof, Attic, and Ventilation Issues Inspectors Flag
Roof condition shows up on almost every inspection report, partly because it is one of the most expensive systems to replace and partly because problems are often visible from the ground or attic. Inspectors look at shingle wear, missing or lifted flashing, and any staining that suggests current or past leaks.
In the attic, they check insulation depth, ventilation components like soffit and ridge vents, and signs of moisture or mold on the underside of the roof deck. Poor attic ventilation can trap heat and moisture, which accelerates shingle aging and encourages wood rot.
Expect inspectors to note:
Shingle granule loss, curling, or patched sections
Gutter and downspout condition, including clogs or disconnected sections
Insufficient attic insulation or blocked soffit vents
Moisture staining, mold, or rot visible on rafters and sheathing
When roof access is limited or unsafe, drone imagery gives a detailed view without anyone stepping onto a steep or fragile surface, and that kind of documentation can be useful to share with buyers before they even schedule their own inspection.
Plumbing: Visible Supply, Drains, Water Heater, and Sewer Concerns
Plumbing problems rank among the issues most likely to stall a closing, mainly because water damage is expensive and often hidden until someone looks closely. Inspectors run fixtures, check for active drips or leaks under sinks, and test water pressure at faucets and shower heads.
They also check the water heater’s age, the condition of the pressure relief valve, and any visible rust or leaking. Visible supply and drain piping gets a close look for corrosion, improper connections, or prior patch repairs.
Sewer lines deserve special mention because they are not visible during a standard inspection, yet slow drains or recurring backups can point to a collapsed or root-infiltrated line. A sewer scope inspection before listing can catch this kind of problem while there is still time to address it without a last-minute renegotiation. Keeping current maintenance and repair records on hand, including anything related to annual plumbing inspections, also helps reassure buyers that the systems have been looked after.
Active leaks, drips, or staining under fixtures and around the water heater
Weak water pressure or inconsistent hot water delivery
Visible pipe corrosion or amateur repair work
Slow drains or gurgling that may signal sewer line trouble
Pro Tip: If your home is more than 20 years old, a sewer scope before listing is one of the more practical steps you can take to avoid a surprise after the buyer’s inspection.
Electrical System Checks: Panels, Outlets, Grounding, GFCIs
Electrical findings tend to generate the most questions from buyers, largely because safety is at stake. Inspectors open the panel cover and look for clear circuit labeling, signs of prior upgrades, and double-tapped breakers, which is when two wires are connected to a single breaker terminal that was not designed for it.
They test outlets and switches throughout the house, checking for proper grounding and confirming that ground fault circuit interrupter (GFCI) protection is present in kitchens, bathrooms, and exterior outlets where it is expected. Older wiring types, like knob-and-tube or aluminum branch circuits, get flagged for a licensed electrician’s review since these fall outside what a visual inspection alone can fully evaluate.
Double-tapped breakers or an outdated, overcrowded panel
Missing GFCI protection near water sources
Ungrounded outlets or reversed polarity
Cracked or missing cover plates on switches and outlets
Replacing a broken cover plate or fixing a dead outlet before listing is inexpensive, and it removes small items from a report that might otherwise make a buyer wonder what else was overlooked.
HVAC, Water Heaters, Fireplaces: What Inspectors Test and Note
Inspectors run the heating and cooling systems through a normal operating cycle, checking for proper airflow, unusual noise, and whether the thermostat responds correctly. They also look at visible ductwork for disconnections, filters for cleanliness, and access panels for safe clearance.
Combustion appliances, including furnaces, water heaters, and fireplaces, get checked for proper venting and flue condition. The NSPIRE inspection protocol guide from HUD emphasizes documenting health and safety items like this because unsafe venting can allow carbon monoxide to accumulate indoors.
Operational test of heating and cooling at the thermostat
Visible duct disconnections or damaged flex sections
Rust, leaks, or an aging tank on the water heater
Flue connections and combustion venting for fireplaces and furnaces
Having your HVAC serviced annually and keeping the receipt gives buyers a simple answer when they ask how the system has been maintained.
Interior and Structural Indicators: Doors, Floors, Walls, and Signs of Movement
Small interior clues often tell inspectors more than they reveal at first glance. Doors and windows that stick can indicate settling, while uneven or sloped floors sometimes point to a structural issue worth a closer look. Cracked drywall near corners, loose stair railings, and missing handrails all get noted as well.
Water staining, peeling paint, or a white chalky residue called efflorescence usually signals past moisture intrusion, even if the area is currently dry. Inspectors document these patterns without guessing at the full cause, since that falls outside a visual, non-invasive scope under the Home Inspection Standards of Practice.
Sticking doors or windows that suggest frame movement
Visible drywall cracking, especially diagonal patterns
Loose or missing stair railings
Staining or efflorescence indicating past water exposure
If you have already repaired a cracked wall or fixed a sticking door, keep the contractor’s receipt. Sharing that kind of documentation separates a cosmetic touch-up from an unresolved structural concern in the buyer’s mind.
Safety and Environmental Checks: Smoke/CO, Radon, Mold, and Hazardous Materials
Safety items carry real weight in an inspection report because they affect people living in the home right away. Inspectors check that smoke and carbon monoxide detectors are present in the right locations and that they respond to a test.
Radon is one of the most commonly recommended pre-listing tests. The EPA’s Home Buyer’s and Seller’s Guide to Radon identifies a specific radon level at which mitigation becomes advisable, and testing before listing lets you address any concerns on your own timeline rather than during a tight closing window.
According to the EPA’s radon guidance, mitigation decisions typically reference this EPA benchmark, which also notes that sellers who test ahead of time can use the results as a point of confidence rather than a point of delay.
Smoke and CO detector placement and function
Radon levels relative to the EPA’s 4 pCi/L guideline
Visible mold or moisture evidence, noted for further testing when needed
Suspected lead or asbestos materials in older homes, flagged for specialist review
Mold, lead, and asbestos are typically recorded as observed or suspected conditions rather than confirmed through lab analysis, so a specialist test is the next step when inspectors flag something in these categories.
How Sellers Should Prepare: Pre-Listing Checklist and Documentation to Gather
A little preparation before the inspector arrives goes a long way toward a clean report. Start with the easy items, then move into gathering your paperwork.
Replace burned-out bulbs and test every outlet and switch in the house.
Clear access to the electrical panel, attic hatch, and water heater.
Clean gutters and make sure downspouts direct water away from the foundation.
Secure any loose railings or handrails on stairs and decks.
Gather maintenance records, repair receipts, and permits for past renovations.

Pro Tip: Decide early which items you will fix and which you will disclose. Safety issues are worth fixing; cosmetic wear can often be disclosed honestly instead.
What an Inspection Report Contains and Common Next Steps
A typical inspection report organizes findings by priority, separating safety and major issues from minor defects and routine maintenance items, with photos supporting each entry.
Safety and major defects that may need immediate attention
Minor or cosmetic issues that rarely affect negotiations
Maintenance recommendations for ongoing upkeep
Photo documentation and suggested next steps for each finding
Buyers and lenders use this report to request repairs, negotiate credits, or, in some cases, respond to a contingency in the purchase contract. According to the CFPB’s guidance on scheduling a home inspection, some loan programs require certain repairs before closing. When a report flags something outside a general inspector’s scope, like structural movement or active wiring hazards, bringing in a licensed specialist and sharing their findings keeps the transaction moving.

FAQ
What is the biggest red flag in a home inspection?
Active safety hazards, like unsafe electrical wiring, gas leaks, or carbon monoxide risks from poor venting, typically concern buyers and inspectors most. Structural movement, such as foundation cracking paired with sloped floors, is the other category that tends to trigger deeper negotiation or a request for a specialist evaluation.
How do I prepare for an inspection as a seller?
Clear access to the attic, electrical panel, and water heater, replace burned bulbs, and test your outlets ahead of time. Gather maintenance records and repair receipts so the inspector and buyer can see the home has been cared for, as outlined in CFPB guidance on home inspections.
What will make a house fail an inspection?
Technically, there is no pass or fail score on a standard home inspection since it is a documentation of conditions, not a certification. That said, significant safety hazards or major structural and system defects are the findings most likely to stall or derail a sale if left unaddressed.
Should I test for radon before listing my house?
Testing before listing lets you see results on your own schedule rather than during a tight closing window, and the EPA’s radon guide for buyers and sellers recommends it as a proactive step. The EPA considers 4 pCi/L the level at which mitigation becomes advisable.
Do inspectors check for termites and pest damage?
Inspectors look for visible signs of pest activity, like wood damage, mud tubes, or frass, as part of the standard exterior and structural review. A confirmed termite or pest infestation usually calls for a licensed pest control specialist rather than relying solely on the general inspection.
