Protecting Your Home From Attic Moisture

If your attic holds a lot of moisture, it can cause a lot of problems for the health of your home. Last week we took a deep dive into the most common culprits of humidity and this week we’ll be talking about how to remedy those issues. To get rid of moisture in your attic, you'll need to identify and address the underlying causes. Here are some steps you can take:

1. Find the source: If your attic humidity level is high, first determine what is causing the excess moisture. The most likely culprits are inadequate ventilation and insulation, roof leaks, or a plumbing issue.

2. Improve ventilation: Most houses that I visit do not have enough ventilation. It’s truly the best way to reduce moisture buildup and keep the temperature in your home more regulated year-round. 

3. Look for air leaks: Check for any gaps, cracks, or openings that might be allowing warm, moist air from your home to enter the attic. Seal these leaks with caulk or weatherstripping to prevent the transfer of moisture. It will also help if critters tend to find their way into the attic.

4. Insulate properly: Insulation helps regulate temperature and prevent condensation. Ensure your attic is adequately insulated to minimize temperature differences between the interior and exterior. Insulation is not just helpful for the winter months, it’s actually crucial year-round.

5. Assess for roof leaks: Inspect your roof for any signs of leaks or damaged shingles or if you’re not comfortable on a ladder, contact a professional. They will inspect both in interior and exterior of the home and be able to advise on appropriate repairs or replacements.

6. Address plumbing issues: If there are plumbing pipes or HVAC ducts running through your attic, check for any leaks or condensation. Repair any leaks and insulate the pipes or ducts to prevent moisture buildup.

7. Control humidity levels: Excessive humidity in your home can contribute to attic moisture problems. Use dehumidifiers in areas with high humidity, such as basements or bathrooms, to control moisture levels. Additionally, ensure your kitchen and bathroom vents are properly vented to the exterior, not into the attic.

8. Monitor and maintain: Regularly inspect your attic for signs of moisture or mildew. If you notice any issues, promptly address them to prevent further damage.

Attics are always tricky because they are so rarely occupied. However, if humidity levels increase the moisture will become a mold problem very quickly, which is hazardous to both your home’s health and yours. When in doubt, always contact a professional for guidance. A licensed contractor will be able to help remediate any problems both in the short and long term.

Attic Moisture Can Lead to Major Damage

As summer humidity begins to ramp up, it’s important to pay special attention to one of the most neglected areas of the home. Your attic can hold a lot of moisture and if it’s not insulated and ventilated correctly, that means major issues for you, the homeowner. In this two-part series, we’ll discuss how moisture can accumulate in the attic and what you can do to protect your home from serious damage. Let’s kick things off with a list of the major moisture-conducting culprits:

1. Insufficient ventilation: Without proper airflow, moisture from the living spaces below can become trapped in the attic, leading to condensation and elevated humidity levels.

2. Roof leaks: Damaged or deteriorating roofing materials can allow water to enter the attic during rain storms or snowmelt. Roof leaks can be caused by missing or cracked shingles, damaged flashing, or compromised roof seals.

3. Plumbing leaks: Plumbing pipes that run through the attic can develop leaks over time. Even a small drip or a slow leak can contribute to moisture accumulation in the attic.

4. Inadequate insulation: As hot and cold air collide, they will condensate or freeze. Without proper insulation and temperature regulation, it’s much easier for moisture to accumulate.

5. Blocked vents: Blocked or obstructed attic vents can impede proper airflow, preventing moisture from escaping. This can result in increased humidity levels and potential condensation problems.

6. Misdirected exhaust fans: If bathroom or kitchen exhaust fans are not vented directly outside, they can introduce warm, moist air into the attic space. This can cause condensation and moisture-related issues.

7. Poorly sealed attic access points: Gaps or insufficient sealing around attic access points, such as doors or hatches, can allow humid air from the lower floors to enter the attic, leading to moisture buildup.

8. Insufficient vapor barrier: A vapor barrier is a layer designed to prevent moisture from passing through walls and ceilings. If there is an inadequate or damaged vapor barrier in the attic, it can allow moisture to penetrate and cause problems.

It's important to address any water issues in the attic promptly to decrease the chances of mold growth, wood rot, or structural damage. Because most people access their attic infrequently, problems often don’t go detected until water starts showing up on the ceiling. Next week we will highlight several ways to protect your home from moisture before it's too late.

What To Do About Warped Siding

A question I get from readers time and time again is about vinyl siding that looks “wrinkled” even when it’s new. Many people think warped siding is an environmental problem and that too much sun and heat or even the contrasting winter cold is what’s creating the damage. Little do they know that warping has very little to do with the weather and a whole lot to do with how it’s put on the home.

Let’s start with the real name of the problem. Siding that is wrinkling or warping is actually called “oil canning” or “stress buckling” and it happens when the siding isn’t installed properly.

All homes are made of natural materials such as wood, which expand and contract with seasonal changes. People love vinyl siding because it’s very low maintenance and offers fantastic curb appeal, but a DIY or inexperienced install can actually make a house look much worse, even with very new siding. 

Every house needs to expand and contract. While it might seem logical to nail vinyl siding tightly to make sure it doesn’t come loose, doing so will actually cause the panel to buckle because it can’t “breathe” with the house. That’s why most vinyl siding panels come with longer nail slots instead of small holes. It gives everything room to move and shift. 

Another possible siding installation pitfall is leaving too much overlap between panels. While you might think this creates a stronger bond, it actually restricts movement, causing the siding to stretch and then buckle in the same way.

Back to my reader’s question. Is there ever a time when the sun might cause siding to warp? The answer is not really, although I have seen damage from sunlight reflecting off an adjacent window. The only other thing that could cause an issue is your gas grill, so keep it far away from the house. 

Once oil canning happens, the siding has to be replaced. Because the issue is installation, the product’s warranty is worthless and the manufacturer isn’t going to be responsible for the defect. While removing panels is pretty straightforward, it can be tough to get a color match if the siding is a bit older. 

These are all the reasons why it’s so important to work with a contractor who knows what he or she is doing. If you’re going to tackle this job on your own, make sure you do your research and know all the common mistakes that can be made. You don’t want all that hard work to result in a home aesthetic that’s anything less than perfect.
