How Your Empty Attic Space Makes Your Roof More Efficient

Preserving heat, insulation, and roof integrity through proper attic care.

Did you know that a clean attic can improve your home’s energy efficiency?Damp, chilly winters in the Portland and Vancouver areas can threaten the integrity of roofs. Fortunately, proper attic care can provide protection for rafters and shingles while improving the efficiency of your home.

Empty Attic, Better Insulation

Attic insulation provides protection for the underside of your roof. However, if your attic is stuffed full of stuff, it’s hard to install or replace insulation anywhere in that space. Attics that are used primarily for storage are often neglected, leading to stagnant air that can result in damage when it comes in contact with heat or moisture from the rest of the house.

Attic Venting

Installing or upgrading attic vents may seem like the opposite of insulating, but proper air flow is essential to a healthy roof. Vented attics stay cool in the summer so the undersides of roof shingles don’t overheat and dry out. In the winter, ventilation prevents the buildup of mold-causing moisture that can lead to the rotting of roof components. When heat rises from the rest of the house, ventilation keeps condensation from turning into frost and prevents unwanted cycles of freezing and thawing.

Sealing Leaks

Poor insulation in the attic can lead to air and water leaks. An air leak not controlled by ventilation leads to a transfer of air from the attic to the outside and vice versa. This makes the attic colder in the winter and hotter in the summer, creating temperature fluctuations that can lead to internal roof damage.

Water leaks soak insulation, destroying its ability to resist heat radiating up from the rest of the house. Wet insulation lets in ambient heat as well as moisture which makes the attic environment not only inefficient but also unfriendly to your roof. As with poor ventilation, wet insulation can lead to mold growth which wears away at the rafters and may cause even more leaks. Plus, if you do store anything in the attic, leaks and changes in temperature will damage your belongings. Together, damage from poor insulation and leaks can lead to loss of property and high roof repair bills.

Installing or replacing attic insulation is a big job. Let Interstate Roofing preserve the roof in your home with the right amount and type of insulation. Our specialists are familiar with “R” value—the ability of insulation to resist the transfer of heat—and can choose the proper level to ensure roof safety and home efficiency.

Where Are All Those Heating and Cooling Bills Going?

Common energy leaks and what you can do.

After investing in state-of-the-art heating and cooling equipment, people reasonably expect their utility bills to drop. Unfortunately, that doesn’t always happen. If it seems like you’re endlessly running your furnace or air conditioner without ever achieving optimal indoor comfort, air leaks around the home are almost certainly to blame. They can occur anywhere from the basement up through the roof, but poorly insulated attics tend to cause homeowners the most grief.

The Importance of Proper Insulation

A well-sealed home is said to have a tight building envelope. The tighter the building envelope is, the more effective the heating and cooling system will be. That’s because conditioned air won’t be able to escape as easily, and outside air won’t be able to get in as easily. Furthermore, radiant heat, which is heat that builds up in the attic and then radiates down into the home, can be mitigated considerably through the use of first-rate attic insulation. When a home is well insulated, especially in the attic, HVAC equipment doesn’t have to work as hard, so energy bills tend to drop. However, it is imperative that you hire an experienced contractor to look at the overall functionality of your home. A tight building envelope can also wreak havoc on your home.

Is Your Attic Causing Your Energy Bill Woes?

Does it seem like the rooms below your attic never get truly cool and comfortable during the summer? If so, chances are that your attic isn’t properly insulated. As the sun beats down on your roof, heat starts bottling up in the attic. Proper ventilation can help to mitigate this to a certain extent, but proper insulation is even more important. With a good “buffer” of blown-in attic insulation, radiant heat won’t counteract your conditioned air nearly as much, so your equipment will be more efficient and effective.

Why Is Blown-In Attic Insulation Superior?

There are all kinds of options when it comes to attic insulation, but blown-in insulation makes the most sense in the majority of cases. It can be blown easily into hard-to-reach places, and it can be applied at any thickness and density. When installed properly, blown-in insulation acts as a highly effective thermal blanket. It won’t settle over time, so it maintains its R-value, which is its ability to resist the travel of heat. The best part of all is that blown-in insulation can reduce energy costs by 15% to 25%.

Lower Your Energy Bills with Blown-In Attic Insulation

Whether you have an older home with old, outdated insulation or a newer one with an attic that was never properly insulated in the first place, blown-in attic insulation is sure to make a huge difference. In Portland, OR, trust the experts at Interstate Roofing to install this highly effective insulation at affordable prices.

Save Money by Insulating Your Attic

The Vampire in your attic… it moved in when your house was built.

Don’t worry, today’s blog post isn’t about a thirsty new pest that has invaded millions of homes. However, this metaphorical vampire could easily drain your bank account. An uninsulated attic can increase household energy bills and expose you to outdoor noise pollution.

Even if you have insulation, it may not be adequate. The Department of Energy urges homeowners in western Oregon to install about a foot of insulation in most attics. You might have too little if the R-value is below 38 or some surfaces remain bare, such as the trap door.

Important Benefits

Everyone knows that heat rises. Attic insulation slows it down, so your heating system doesn’t have to work as hard in the winter. More insulation allows you to spend less money on electricity, fuel and furnace repairs. It also reduces the air pollution that your home generates.

Thick insulation will cut your cooling expenses, too. An uninsulated attic becomes very hot when the sun shines on a roof during the summer. Insulation makes it more difficult for this heat to enter your home, so you won’t have to use fans or air conditioners as frequently.

A well-insulated attic may also come in handy if you decide to sell your property. Many homebuyers prefer to save time and money by selecting houses that have plenty of insulation. This upgrade will help you sell your home faster and achieve a higher selling price.

Insulated attics muffle distracting outdoor noises that normally penetrate a home’s roof. Rain, hail, thunder and wind won’t sound as loud. Likewise, insulation may block noise from airplanes or helicopters. This is a major bonus if you live near the airport in Portland, OR.

You might obtain a generous rebate or tax credit by insulating your attic. Some utilities, state agencies and nonprofit organizations offer such incentives in the Pacific Northwest. The government also allows many homeowners to claim federal tax deductions when they buy insulation.

Cold in the Winter, Hot in the Summer

Are you sick of watching your home’s energy bills skyrocket during the winter and summer? Although the Portland-Vancouver area enjoys pleasant transitional seasons, winter’s chill and summer’s heat are constant threats to local household budgets and home energy efficiency. Fortunately, there are several cost-effective steps you can take to reduce your heating and cooling bills without investing in costly new technologies.

Leaking Air, Leaking Money

Many older homes suffer from poorly sealed windows, under-insulated attic spaces and drafty doors. Energy-saving retrofits typically focus on three key areas: attic insulation, window replacement and whole-house weatherproofing. Let’s explore each of these in turn.

Keep It Comfortable with Affordable Insulation

Home energy efficiency depends on a variety of factorsAccording to the EPA and the administrators of the federal government’s EnergyStar program, homeowners can save as much as 20% on total heating and cooling costs simply by adding new insulation to their attics or updating existing insulation within their homes’ walls. This translates to total energy bill savings of as much as 14%.

What’s more, Oregon and Washington both offer additional rebates that may cover part of the cost of installing blown-in insulation in your attic. When it’s done by a professional, the installation process is fast, effective and non-disruptive.

Replace Outdated Windows

Window replacement is another important step. Like attic insulation, energy-efficient windows routinely attract federal and state tax credits. Modern windows use effective sealing technology to keep warm air inside during the winter and outside during the summer. In fact, the newest generation of energy-efficient windows doesn’t even require a second storm window to function properly. Instead, modern windows contain insulating buffers between “inside” and “outside” panes. Many models last for years, so you’ll enjoy ample returns on your modest investment.

Simple Weatherproofing Tips for Year-Round Comfort

Other weatherproofing steps may be even easier. Fireplace inserts effectively insulate your home’s chimney column and reduce heat loss through the roof. Programmable thermostats allow you to control how much heat or air conditioning your home’s interior receives at any given time. Meanwhile, costs for energy-efficient heating units and solar panels have plummeted over the past decade.
