For practical reasons, most people looking to buy a house don’t inspect the roof of a prospective home. However, that section of the house can present serious and costly problems if it has any kind of damage.

Asking about the condition of the roof is paramount. How old is it? What is it made of? Buyers can find this information on the seller’s disclosure or ask the real estate agent to find out. Asphalt shingle roofs last around 20 years, but other materials, like clay or metal, can last much longer.

It goes without saying: safety is a big thing. When searching for a home, make sure the neighborhood where a potential house is located is safe. It’s also highly advisable to check out the neighborhood from an insider’s perspective via social media, such as Facebook groups, where you can learn more about the area and ask locals questions.

If you’re truly interested in a particular home, spend some time in the neighborhood. Go for a walk and check out local businesses to get a feel for what it’s like to live in the area.

The HVAC system heats and cools a house year-round. Anyone looking at houses should ask about the type of heating and cooling system each one has and, most importantly, how old it is. Asking for maintenance records is also a good idea.

Furnaces and AC units typically last anywhere from 10 to 25 years. If a unit is broken, repair costs vary based on the type of system and how big it is. Homeowners can spend an average of $7,000 to replace an existing HVAC unit—but don’t count on a home warranty to automatically cover that.

5

Property Taxes

A commonly overlooked item for first-time homeowners when searching for a house is property taxes. When considering a potential home, always compare property tax amounts over several years to help you calculate the overall affordability of the property .

To find out a home's estimated property taxes, check with the county's appraisal board. Homeowners Association dues should be listed in the home's listing, or you can request them from the listing agent.

6

Plumbing

The plumbing system in a house can be a mystery for a prospective buyer if they don't know how to inspect it properly. Pipe disintegration, obstructive tree root growth, and complicated clogs can all cause havoc on the system. Keep in mind that sewer line replacement can cost anywhere from $1,300 to $4,900.

Always check toilets for leaks, unstable bases, and discoloration . Look under the bathroom and kitchen sinks for signs of leaks. Turn on the hot water in the sink or tub to see if it gets hot. If it doesn’t, that could indicate a problem with the water heater.

7

Water damage and mold

Image: Hydra 4x

Water damage can cause numerous problems in a house, including structural issues, mold, and rot, especially in basements. Anyone inspecting a house should pay close attention to musty smells as well as water stains on floors, walls, or ceilings .

The cost of mold removal can be anywhere from a few hundred to a few thousand dollars, depending on the size of the affected area. And, because mold is a health hazard, it should be treated before moving in.

8

Proper ventilation

Image: Jelleke Vanooteghem

This one might be subtle, but it’s very important, especially when considering the mold issues mentioned earlier. Without adequate interior ventilation, moisture can't evaporate , which can turn a room into a breeding ground for mold.

Look for condensation on windows or slightly bubbled or peeling paint around windows, doors, or vents. These signs may indicate moisture within the walls or ceiling drywall.

9

Noise Level

Image: Rei Kim

Nobody wants to live in a noisy home. But, at the same time, this issue is often overlooked when searching for houses. Many showings are cunningly scheduled during quiet hours to disguise the noise issues.

If you are truly interested in a property, visit during high-traffic hours to assess this concern . Even if the house is perfect in every other way, the constant hum of passing cars, public transport, or other sources of noise can become a serious problem.

10

Foundation and home exteriors

Image: Aiden Craver

Foundations matter. Bulging or bowing foundation walls are signs of structural weakness that can be expensive to repair. Always check for cracks in the foundation, drywall, or ceiling ; gaps above doors and windows ; sunken stairs or porches; and sloping or uneven floors or tiling.

Of course, not every crack means the home is about to collapse. Every home experiences some degree of settling, so some cracks are to be expected.

11

Electricity issues

Image: Mila Albrecht

The electrical system in a house can be compared to the nervous system of a human being: every part must work properly, and issues can sometimes be difficult to spot. From the power outlet next to the bed to other electrical systems in the house, like the garage door opener, everything is important and contributes to your safety and comfort. Bring a phone charger and plug it into random sockets to check if they work properly .

12

Room for improvement

Image: Daniel McCullough

Buying a house is a big investment and you can be living in it for a very long time. Therefore, it is always important to take into consideration any future plans and whether these plans make sense in that particular house.

Is there a wall you could knock out to create more space if needed? A garage or attic you could potentially finish if you need an extra room? Having an easy-to-modify layout can provide more possibilities for the future.

The Dust Bowl

Image: Sophia Simoes

The 1930s Dust Bowl was a man-made disaster exacerbated by a severe drought across the Great Plains. Decades of over-plowing and unsustainable farming practices had left the farmland highly vulnerable to erosion.

When the drought struck, winds swept loose soil into colossal clouds that darkened cities and devastated remaining crops. These massive dust storms, known as "Black Blizzards," choked the skies and forced thousands of families to abandon their homes . Eventually, the disaster led to significant agricultural reforms under the New Deal.

Lake Michigan's seiche wave

Image: Silas Baisch

On the morning of June 26, 1954, a 10-foot-high seiche wave crashed onto the Chicago shoreline , sweeping away eight people and injuring many others. But what exactly is a "seiche wave"?

According to researchers, seiche waves are large, sudden standing waves that form in enclosed bodies of water due to extreme atmospheric changes, such as abrupt shifts in air pressure or strong winds. This rare event shocked the Midwest and prompted scientists to study lake oscillations and their connection to storm systems.

Great Alaska earthquake

Image: Joris Beugels

In 1964, Alaska was struck by a devastating earthquake with a magnitude of 9.2, making it the most powerful ever recorded in North America and the second most powerful worldwide. Lasting four minutes and thirty-eight seconds, the earthquake triggered massive tsunamis and landslides across the state, along with significant geographic changes —some coastlines sank while others rose dramatically.

The destruction it caused led to major updates in seismic safety protocols and infrastructure standards throughout the U.S. This event emphasized the need for better preparedness and stricter building codes , to handle similar future events, especially in earthquake-prone areas.

5

Hurricane Katrina

In 2005, Hurricane Katrina ravaged New Orleans and the Gulf Coast, claiming more than 1,300 lives and leaving millions homeless, sparking an urgent humanitarian crisis. The storm caused an estimated $125 billion in damages, making it one of the costliest hurricanes in history , tied with Hurricane Harvey in the Atlantic basin.

Katrina exposed critical flaws in the region's levee systems and emergency response efforts, prompting widespread criticism and driving essential reforms in disaster preparedness and infrastructure.

6

The Peshtigo firestorm

Image: Tim Mossholder

On the same day as the Great Chicago Fire of 1871, a catastrophic firestorm near the small town of Peshtigo, Wisconsin, scorched approximately 1.2 million acres, making it the deadliest wildfire in recorded history . The uncontrolled blaze claimed over 1,500 lives, though the exact number of fatalities remains uncertain.

Since 1883, there has been speculation that the simultaneous outbreaks of major fires across Illinois, Michigan, and Wisconsin, including the Peshtigo and Chicago fires, were not coincidental but caused by burning fragments from Biela's Comet . However, this theory remains unproven.

7

Superstorm Sandy

Image: Matt Hardy

Nicknamed "Superstorm" by the media, Hurricane Sandy wreaked havoc on the Caribbean and the coastal Mid-Atlantic region of the United States in late October 2012. While it affected 24 states, the most severe damage was concentrated in New Jersey and New York .

The storm caused an estimated $70 billion in damages, flooding New York City's subway system and displacing thousands of residents. It also ignited a nationwide debate about the role of man-made climate change in amplifying the intensity of seasonal storms.

8

Death Valley heatwave

Image: Johannes Plenio

Death Valley recorded the world’s hottest temperature —134°F—in 1913. A testament to America’s climatic extremes, the region’s unique topography traps heat, effectively turning it into a natural furnace.

While the record remains a point of fascination for meteorologists and tourists alike, some recent researchers have challenged the accuracy of the 1913 measurement. Regardless, the region has come close to this temperature in recent years, indicating that a new record-breaking summer may be in the cards.

9

The Great Blizzard of 1888

Image: Jan Canty

The "White Hurricane" of 1888 buried the Northeast under as much as 55 inches of snow, crippling major cities and resulting in over 400 fatalities. Railroads were shut down, and many residents were confined to their homes for up to a week.

As one of the most severe blizzards in American history , the storm compelled New York City to bury power lines and redesign its transportation systems to better withstand future extreme weather events.

10

Mount St. Helens eruption

Image: Tetiana Grypachevska

On May 18, 1980, Mount St. Helens erupted in Washington, triggering massive landslides and pyroclastic flows, killing 57 people and causing over $1.1 billion in damages. The violent blast also reduced the mountain’s height by more than 1,300 feet and sent a plume of ash 80,000 feet into the atmosphere, disrupting air travel for weeks.

This volcanic event, the first in the contiguous United States since the much smaller 1915 eruption of Lassen Peak in California, is considered one of the most disastrous volcanic eruptions in U.S. history. Its aftermath raised awareness of volcanic hazards and underscored the importance of geological research in the country.
