How Does Your Attic Suffer During Summer?

May 17, 2024

It's a great day to go out and have fun on the parks and streets. As the sun's out, your home's facing the brunt of the heat. Your roof and attic absorb more heat and can cause significant problems to your home if you're not careful. Here are several ways your attic suffers during summer.

High Temperatures

During the summer, attics can reach sweltering temperatures, often exceeding 150°F. This intense heat can warp wood structures and even dry or melt insulation. 

High temperatures also make it harder for your air conditioning system to keep the house cool and can mean higher energy consumption and possible need for comprehensive repairs. 

Proper attic ventilation can reduce possible damage and higher energy bills on your property. You can install vents or an attic fan to improve your roof and attic temperatures.

Moist and Humid Attics

Summer brings not only heat but also humidity. A moist and humid attic creates an ideal environment for mold and mildew growth and causes irritation and health risks to occupants. Mold spores can spread through the air and exacerbate respiratory problems and allergic reactions. 

To combat humidity, consider using a dehumidifier in your attic and ensure proper ventilation. Letting old air out and fresh air in a proper circulation system can prolong the lifespan of your roof and your attic. 

Sealing any gaps and cracks can also prevent moist air from entering the attic. It may require a specialist to do properly, so ask your local roofing contractor for help.

Underlayment Problems

The underlayment of your roof is a critical component that provides an extra layer of protection against water damage. 

However, high temperatures and humidity can deteriorate the underlayment over time, compromising its effectiveness. Weak underlayment lets water seep through and cause water damage. 

Fortunately, regular roof inspections can help identify underlayment issues early and have you replace worn-out underlayment before it fails completely and you save from costly repairs.

Small Animal Infiltration

Summer is also a peak time for small animals, such as squirrels, raccoons, and birds, to seek shelter in attics. 

These animals can cause significant damage by chewing through insulation, wiring, and wooden beams. They can also eat through your asphalt shingles – even their droppings are highly acidic to cause damage to your roof material. 

In your attic, these pests may also create nests, leave behind droppings, and contribute to mold and mildew growth. 

To prevent animal infiltration, ensure all entry points, such as vents, chimneys, and gaps, are securely sealed. You can use circular deterrents to discourage squirrels and other small, climbing animals from accessing your attic through the downspouts.

Installing mesh screens over openings can also deter animals from entering your attic. You will need an expert contractor to design your mesh barrier for optimal performance.

Higher Likelihood of Summer Rain Leaks

While summer is generally associated with dry weather, many regions experience sudden and heavy rainstorms. If your roof and attic are not adequately prepared, these rainstorms can lead to leaks. 

Again, regular roof maintenance lets you inspect and replace missing shingles and clear gutters just in time before the rainstorms arrive. Additionally, ensure that your attic has a proper drainage system to handle any water that may enter.
