Is My Home Well Insulated?

You don’t want to wait until it’s too late to find out that your home’s insulation is failing. When winter blows in and there’s nothing but a chill in the air of your home, you’re going to wish you paid attention to the signs that your home’s insulation is under-performing. There’s ways to know before it’s too late, if you pay attention to what your house and the weather is trying to tell you.


While cold spots are the obvious sign that you’re facing an under-insulation issue, there are more nuanced ways to find out your home isn’t being insulated as well as it could be.

From energy bills to water and ice buildup. There are many ways to tell that your insulation isn’t doing its job.

We’ve outlined some of the most important signs to look out for if you fear your home isn’t insulated properly.


Cold Spots

This is obvious but needs to be said. If you experience a temperature fluctuation in different rooms, at different spots in rooms, or even in the walls or windows, chances are the insulation is failing. You’re not supposed to have drafts within the home, so presence of colder air, distributed strangely throughout a space, is a sign that you have an insulation problem.


Excessive Amounts of Pests

While the first instinct when you come across an infestation of rodents or bugs is to call an exterminator, you might want to make another call to a pro for insulation. Because those pests are getting in from somewhere. The same way cold air takes advantage of gaps in the insulation, pests do the same thing. So if you’ve got a pest problem, take a look at the cause because it might be your insulation.


Frozen Pipes & Ice Dams

If pipes in your walls are frozen or ice dams are forming on your roof, it’s a good indicator that your insulation is failing. Pipes freeze when they’re exposed to cold temperatures because insulation is not keeping the heat from your central system. As for the ice on your roof, this results from heat not staying contained and melting the lower layer of snow on your roof which then refreezes and forms sheets of ice.

How Does This Affect My Energy Bill?

Your energy bill is going to be another place where you’ll want to look for the possibility of an insulation issue. Because the heat doesn’t stay in the home, your heater will constantly kick on to try and get the house to a stable temperature. This is also true in the summertime for the AC system as the home becomes unable to hold in cool air as well.


How Do I Fix Bad Insulation?

If you decide you’ve got an insulation problem, start by assessing the situation and taking inventory of where it’s coming from. Do some research on the type of insulation you want to install and research local pros. While it’s possibly to insulate yourself, consulting a professional is recommended, especially for insulation around power outlets. There’s plenty of handy tools out there to help you calculate your cost.


Don’t wait until it’s unbearable to deal with bad insulation in your home. There are ways to tell something is wrong and it can be an easy fix if you do the right amount of research and preparation. Calling a reputable local Home Improvement Contractor is a great place to start.

The Anatomy of a Roof Many people might underestimate the complexity of a roof, thinking it contains mostly shingles and perhaps a wood underlayer. If that were the case, though, roof leaks would be an epidemic in neighborhoods throughout the nation. In reality, while shingles in most cases form the most visible aspect of a residential roof, other elements must be present to provide true weather protection. At 180 Contractors, we know what goes into a quality roof and how these components protect the value of your home. Here is a closer look at the anatomy of a roofing system. Going Beyond Shingles Shingles come in a few varieties, but most shingles are made of asphalt and have a lifespan of around twenty years. When installed by a professional roofing contractor, shingles prevent water from penetrating the wood below. Beneath the shingles is an underlayer that is often composed of synthetic material. This layer repels moisture and prevents water infiltration. Additional elements of the roof system work in harmony: The flashing is made of metal and is needed alongside chimneys, dormers, and skylights The ridge vent runs horizontally along the roof peak and exhausts hot air from the attic The roof deck refers to the wooden underlayer A metal drip edge facilitates water runoff in the eave area The hip refers to the intersection of two roof planes and requires special hip shingles Looking at the Complete Package A failure of any component in your roofing system could spell trouble. Just one leak has the potential to cause damage to the structure of your home as well as its contents. A quality roofing contractor will understand the functions of all parts of your roof.
