Protect Your Roof Better

The roof of your home is actually several layers of protection to keep you safe from the elements. The materials on top, like shingles, are the first line of defense for your roofing. Then it’s underlayment sheathing and finally your roof deck.

Since the wood of your deck is susceptible to moisture, air circulation is pivotal. That’s where insulation and attic ventilation come in. Not only can they increase the longevity of your roof, but they can have other effects.

You lose a surprising amount of air from bad insulation, for example, and those gases can harm the ozone layer. The lost heat also makes your AC unit push harder, which can raise your bill and lead to expensive repairs for the unit itself.

Correct ventilation and insulation can protect your roof better, so you should get a professional. Northland Roofing, LLC has a team of installation experts that can help. When you’re ready, give us a call at 845-251-6461 today to schedule your free inspection!

Benefits of Attic Ventilation

Insulation is only half of the real potential for your roof, because ventilation is key to air flow through your attic. Stagnant moisture and water invite bacterial mold growth, which can be disastrous for your roof deck. However, you might not realize how many benefits there are to proper ventilation:

  1. Getting the obvious out of the way, you lower chances of mold and mildew affecting the wood
  2. Some of your roofing, especially if you chose a metal roof, will rust when there isn’t enough air flow
  3. Asphalt shingles will begin to crack, peel, or bubble up if there’s moisture underneath
  4. Ventilation keeps water from collecting on your roof, which can avoid ice dams when it’s cold out
  5. Since your roof deck is responsible for keeping the roof over your head, it has to stay dry with air circulation

Having the right amount of ventilation in your attic space can increase your roof’s longevity. Without it, you could face excessive humidity and moisture that will damage the roof deck. Once that happens, the wood will weaken and your home could be in danger.

Of course, you also need to make sure there are enough vents to let them work efficiently. We’ve got the experience to know how many vents your home should have, especially with larger homes. If you’re looking for a roofing company that you can trust with your roof’s safety, call 845-251-6461 now and get started with a free estimate!

We mentioned it earlier, but it bears repeating: About half of the air in your home is lost through the floor of your attic. Knowing that a big percentage of this is because of poorly-installed or old insulation, you need an expert. However, insulation can only do so much without the air flow provided by proper ventilation. The two factors have to work in tandem for your roof to thrive.

Before anything gets installed, though, our team will comb through your attic and the rest of your home for leaks. Obvious signs are water stains on walls or the ceiling, especially near circuit breakers and recessed lights. Our eyes are trained to spot these kinds of problems.

The reason we do this first is because leaks will ruin the purpose of insulation. No matter how strong or thick it is, insulation can’t retain air if there’s a hole down the hall. We’ll patch whatever leaks we find and get to work on your insulation!

Hire a Professional for Your Ventilation and Insulation

Something that we’ve come to learn after enough roofing is that some things apply to all houses. Obviously, we’ll clean or unblock the vents in your home and install your insulation properly, but that’s just the start. For everything in your house to work correctly, you need the right ventilation types, amount of vents, and enough air circulation.

The good news is that we’re familiar with all of these rules and we’ll apply them when looking at your home. For instance, we know that you need the same amount off ridge vents as intake or exhaust vents throughout your house.


Another reason to work with a professional is because we know the local ventilation codes. Many areas require a vent to be installed every 150 square feet, though some push it to 300. This is to ensure you and your home are in safe conditions.

To elaborate on an earlier benefit, you can save money with the right ventilation and insulation. Better air flow means fewer roof repairs caused by mold or weakened wood. Insulation retains temperature better, so you’ll save on your electric bill. Whatever piques your interest, it’s worth it to call us at 845-251-6461 today!

The Value of Insulation

Most homeowners aren’t familiar with the different types of insulation that get used, and that’s okay. The main 3 that our customers like to choose are:

  1. Fiberglass
  2. Loose-fill
  3. Blown-in

Fiberglass comes in batts that can be unrolled and layered for whatever thickness your roof needs. As a material, fiberglass is thick and quick to install. All of those reasons could save you in the long-run on the installation costs with less labor and time.

You might not think about fiberglass for temperature resistance, but it’s one of the best for a reason. Because it comes in rolls, you’ve got options for thickness that will decide the R-value of your insulation. Loose-fill and blown-in are other common choices among homeowners, though.

Loose-fill is similar to fiberglass in the way that it can reach whatever thickness you need, but it’s closer to blown-in insulation in texture. The latter is effective and easy to control how much we’ve installed. Before we do any installation, we’ll install baffles first to keep insulation out of your vents.

Without the baffles, our vents could get blocked and defeat the purpose. Professional installation will make sure everything is done right, but we’ll also make sure that your insulation reaches the correct R-value for your area.

The R-value is a measurement for insulation that tells its thermal resistance. Knowing how much of a material is needed to retain your cold and hot air is part of our planning process. That’s how we figure out the required thickness and material amount to use.

An easy example goes back to the rolls of fiberglass compared to loose-fill. We can layer your fiberglass batts in the open area of your attic and get to the right R-value, but loose-fill can get to the same value in tighter quarters. If you’re still on the fence, here are 2 of our most-common answers:

  1. Fiberglass and loose-fill are used the most among homeowners for their cost and ease of use. How your roof is shaped and how large it is will help us suggest which material would be best for you.
  2. There are several different materials, but which one you choose can hugely affect the overall installation cost. Because it’s measured in square feet, a lot of homeowners go with rolls of fiberglass to be more cost-effective.

Basically, there are insulation options available and we’ll recommend the best for your situation after our inspection. Like ventilation, there are local codes that must be met for R-values. When you call 845-251-6461, you’re getting all of our experience and knowledge to work for you!
