Winter can be harsh on your home. Freezing temperatures, snow, and ice can cause various problems if you're unprepared. Homeowners often underestimate the potential damage cold weather can cause.

Winter storms caused over $15.5 billion and $10 billion in insured losses in 2021 and 2022, respectively. In 2023, this figure dropped to around 3.3 million. But don't worry! You can take measures to safeguard your house and ensure it remains snug throughout the colder months.  

Unexpected winter storms like early 2024’s Hilary, which brought nearly 2 inches of rain to downtown LA, can cause colossal losses. It’s crucial to address any existing defects. Start with the roof and hire a professional if the damage is widespread. It can save you headaches and money, ensuring your house remains snug throughout the colder months. 

Along with roof maintenance, here are five crucial tips to help winter-proof your home effectively.

1. Inspect and Fortify Your Roof

Your roof is your home’s primary defense from winter storms. DisasterSafety.org suggests starting by conducting a thorough inspection. Check for chipped or missing shingles, corroded flashing, or jammed gutters. Fixing them can minimize water leaks or ice dam buildup. Check for signs of leaks, moss, or algae growth. These issues can worsen with snow and ice. 

In Southern California, where wildfires are a concern, also check for ember damage and clear any debris that could ignite. Clean your gutters and downspouts of leaves and residue to minimize water stagnation and ensure seamless discharge. Consider using gutter guards to limit future repairs. Make sure your downspouts face away from your structure. 

If you spot damage, act immediately—delaying repairs can escalate problems, especially during heavy snow or freezing rain. Remember that even in sunny LA, winter storms can bring heavy rainfall, putting a strain on your roof. Finally, consider your attic's insulation. Proper insulation helps regulate your attic temperature. 

This can prevent ice dams by minimizing the heat escaping through your roof. A professional inspection can identify less visible issues, such as weakened roof underlayment, saving you from expensive repairs later. If you're unsure about your roof health, book a roof repair by LA Roof Masters for a professional assessment and any vital upgrades.

2. Seal Gaps and Drafts Around Doors and Windows

Most homeowners in the US ignore insulation and sealing. ENERGY STAR reveals that 90% of US homes are underinsulated. Proper insulation and sealing can help cut average energy costs by 11%. Window and door drafts can worsen utility expenses by letting warm air escape. Check for gaps by feeling cold air or using a candle to detect drafts.

Seal small gaps with caulk, and for larger spaces, weatherstripping is an effective solution. Caulk can fill any gaps around the frames. Remember to install door sweeps to block drafts at the bottom of your doors. Angi advocates installing insulated window film or heavy thermal curtains to add a layer of warmth. 

With LA's mild winters, you might think insulation isn’t crucial, but it will impact your energy bills and comfort. If you have a fireplace, remember to repair it regularly. This reduces the likelihood of accidental fires, provides hotter fires, and efficiently heats the home. A professional cleaner will charge you $130 to $380 for a thorough cleaning.

3. Ensure Your HVAC System Is Winter-Ready

A well-maintained HVAC system ensures efficient heating throughout the winter. Begin by replacing air filters to maximize ventilation and indoor air hygiene. Old filters impede airflow and lower system output. Reader’s Digest suggests cleaning or replacing them every 1–3 months. This can help you eliminate as much as $30 per month.

Test your thermostat to confirm it’s working smoothly. Experts advise adjusting your thermostat between 68 and 78 degrees in the fall. This strategy can save up to 10% on annual heating costs. Consider transitioning to a smart thermostat to optimize heating schedules. If you use radiators, release the clogged air to improve their efficiency. 

Additionally, reverse your ceiling fans clockwise. Since warm air is thinner than cold air, it stays near the ceiling. By changing the fan direction, the fan pushes the warm air toward the floor. This reduces the thermostat load and lowers the energy bill. 

Schedule a professional tune-up to address issues like clogged vents, worn-out components, or improper calibration. Furthermore, you also consider earthquake implications due to the region’s proximity to the San Andreas Fault. Ensure your HVAC system is properly secured to prevent damage during seismic activity.

4. Prepare Your Pipes to Prevent Freezing

Frozen pipes can crack and cause extensive water loss, which is costly and stressful. The American Automobile Association (AAA) estimates the standard local frozen pipe claim costs over $11,000. Depending on the damage to domestic property, this figure can increase drastically. 

You can avoid this by insulating exposed pipes in basements or attics with foam sleeves or heat tape. Before the first freeze, unplug garden hoses and cover your outdoor faucets. This prevents water from freezing inside and potentially bursting the pipes.

Allow faucets to drip slightly with warm water on colder nights to keep water flowing through the pipes. You can also leave the unit open so the radiation can reach the pipes. While freezing pipes are uncommon in coastal areas, homes in the foothills or valleys are still at risk, so it's best to take precautions.

5. Reinforce Your Home’s Exterior

Winter weather can do a number on your home’s exterior. Inspect siding, decks, and foundations for visible damage. Fill the foundation cavities to reduce water absorption when snow melts. Wash your siding and apply a weather-resistant sealant to ward off dampness and snow. Similarly, check your deck for loose boards or nails, and add a fresh coat of paint or sealant to shield it from ice damage. 

Reinforcing these areas ensures your home remains structurally sound despite harsh conditions. You can also install removable interior and exterior storm windows. US News Real Estate recommends trimming tree branches near your house. Overhanging branches can break under snow weight, causing property damage, power outages, or injuries. 

Experts suggest pruning trees when they’re dormant. It facilitates tree growth and helps stabilize the tree’s framework. Create a buffer zone around your home to minimize potential winter-related structural risks. With Santa Ana winds common in the LA area, trimming trees is key to preventing damage to your home and power lines.

Commonly Asked Questions

Q1. What are some common winter hazards around the house?

Watch for icy sidewalks and driveways. Keep them tidy to minimize slips and falls. Also, be mindful of carbon monoxide risks from heating systems. Ensure proper ventilation and install carbon monoxide detectors. Finally, be aware of fire hazards from fireplaces and space heaters. Keep flammable materials at a safe distance.

Q2. Can I winter-proof my home by myself?

Many winter-proofing tasks are DIY-friendly, like caulking windows, installing weatherstripping, and cleaning gutters. However, complex tasks like roof repair, chimney cleaning, or HVAC maintenance are best left to professionals to ensure thorough and safe preparation.

Q3. How early should I start winter-proofing my house?

Start winter-proofing in early fall, ideally between September and October. This gives you ample time to complete repairs, seal drafts, and prepare your home's exterior before the first frost. Early preparation prevents last-minute rushed fixes. Aim to complete your tasks by November or early December.

Winterizing your home is an investment in safety, comfort, and long-term savings. By taking these steps, you can minimize winter-related damage and enjoy peace of mind throughout the season. Now is the time to act and prepare your home for what winter might bring. Start early and take proactive measures. Your home will thank you when the cool weather hits.
