Proper ventilation in your roof is extremely important and whether you have an attic or standalone style roof.

It is important to have a well ventilated area under your shingles, and in this article we will explore the many different conditions that need to be met to be considered “Good Ventilation”. By exploring these benefits we can see just how important a focus on ventilation is for any roofing system.

Ventilation affects the lifespan of your roof! In Memphis, we have very wild weather. One minute it is 30 degrees, the next it is raining! This week has been a perfect example. In addition, Tennessee Winters are relatively mild, which means most homes do not take cold weather into consideration. However that few days of 10 Degrees every year, year after year with a sudden return to heat can cause havoc on a homes attic ventilation system. A Ventilation system that is not adequate then reduces the life of your roof, the R-value of your insulation of your home and the result is energy inefficiency and repairs that cost THOUSANDS!

And it’s all easily avoidable and affordable to fix!

What exactly happens when you have an limited or unbalanced ventilation system?

Good questions, proper ventilating protects the structural integrity of your roof deck, and thus your home! Limited Ventilation can make your home more difficult to keep cool in the summer. Shingles are typically dark, and as the sun beats down on them, that heat radiates into your attic, and then into your home. Increasing your air conditioning costs! Limited ventilation can also make it more difficult to heat your home in the winter, as the resulting moisture from condensation or leaks results in humid damaged insulation, which decreases the R value of the insulation, and thus puts more load on your furnace as well to keep your home warm.Showers, sunlights, and kitchen areas not allowed to properly dissipate heat also cause a reduction in your homes heating, cooling, and insulating effectiveness. Humidity can be a huge factor with these areas.

How Common is this?

Most of the homes we inspect, and visit for estimates, have ventilation to minimal code. This means it is “Good enough” to not cause your house to rot like a hut in a 3rd world country, but it certainly doesn’t have that “Built to Last” mindset behind our PRO WAY promise of contracting excellence! For less than $1000 a home owner can have us come in, adequately ventilate the home, and see their roof last up to twice as long as a poorly vented home.

Considering a roof costs $5000+ I would say that is a good investment! This is not even considering the heating and A/C savings as well as the preventing of costly leaks and water damage. Long Story made short, proper roofing ventilation makes your home run more efficiently, and allows each piece of your homes mechanical system to do its job better. A chain is after all, only as strong as its weakest link!

Bonus! Do Whirlybirds actually Work?


Yes, and No, but barely better than a typical 6050T or other typical button or square roof vent. The difference is once the Whirlybirds stop “Whirling” they work even worse than a typical vent, and open your home up to all kinds of leak potential in the process. It’s kind of like Installing a big ugly “Fast and Furious” spoiler on a Toyota Camry. It doesn’t turn the car into a race car, it would probably be worse in the long run, and drilling holes in your trunk with your dads power drill is probably going to cause rust down the road. They were a gimmick in the 90’s and they still are.

I suggest asking one of our Roofing Experts about Turbo Vents, or Ridge Vents during your roof replacement consultation! 


For these reasons and more, it’s important to do regular inspections and to perform repairs and maintenance to ensure that your roof has proper ventilation. Ideally, your attic should be closer to the temperature outside than inside, if not the same as outside. If it is hotter than your home in the winter, that is a problem!

Always remember to be safe and know your limits when performing your own inspections on rooftops or attic spaces. If you are ever unsure call the professionals at ContractingPRO we would be happy to assist you!

Put an End to Shingles Blowing Off the Roof

How SureNail Shingles can Help

It’s not every day that a shingle blows off your roof, but when it does, you probably hope that it would fall on your front door step right? Of course it would be best if the shingles, you know, stayed on the roof where they belong but if blown off shingles were a fact of life it would be nice to know when it happens right?

Well that is not always the case, in most cases they land somewhere else on the roof or get caught in gutters, neighbours trees, or only get half ripped and stay attached but causing some kind of odd water flow issue on your house roof.

So if those shingles do not land directly on your doorstep for you to be alerted to the now exposed hole in your roof, it could lead to a huge problem down the road. When you notice a piece of roofing material on the ground it is important to Call a roofing contractor right away. There is no “Extra” roof material on your home. Every inch of your roof covering is installed with a purpose and cut to measure. If your roof was installed the PRO way with a total protection system including underlayment, you are certainly in a better position because there is an added layer of waterproofing in the form of membranes and ice and water shield.

However this is a commonly overlooked factor in roof construction, especially on new builds and should never be expected unless you are sure of the components installed.

Can’t this just be prevented!?

Absolutely! This has been a common problem with the engineering of shingles, and the installation for decades and finally someone has come up with a solution to the problem of blown off shingles!

Typically the polymers, asphalt, and granules used in the construction of shingles have been pursuing great waterproofing and shingle life but the problem is that as you make a shingle more rubbery and malleable, it doesn’t get any stronger. If the wind gets under a shingle it’s still just as easy to pull the shingle of, slowly tear a bigger and bigger hole around the nail and eventually come off. That is the biggest misconception about blown off shingles, it doesn’t start the day of a big storm! It starts with the installation, if the tabs are not totally sealed down to the layer below, you will be at risk of a blow off. Then over time, the shingle gets more and more worn down and eventually a bigger storm rips it right off.

Then someone at Owens Corning got a GREAT idea, what if they engineered something that is not focused around improving waterproofing but instead of increasing the strength of the shingle? Introducing SureNail! By embedding a reinforced mesh in the nailing zone, any nail driven through is now locking that shingle in place! If wind finds its way under the shingle edge, it might flab but thanks to the mesh a nail cannot rip through the shingle.

That’s it?

Not in the least! There were some awesome benefits to following this train of thought. The second most common reason for blown off shingles is when installers improperly fasten the shingle to the roof by nailing either too high, or too low. Adding the SureNail strip forced a larger common bond area, which makes the nailing zone easier to hit, and with a giant white mesh strip installed it became even easier to see during the busy roof installation environment.

In addition to that, the sealant the underside of the shingle installed next, seeps into the mesh and provides an incredible adhesive area that locks shingles in place. Combining all these awesome benefits gets you an incredible high wind warranty and weather proofing that cannot be matched in the industry!

What about the installation?

That is the best part! Not only does it perform better, but with only 4 nails required to get this high wind warranty it is a GREAT option for home owners looking for great value! Because the shingle is dream for our installers! It is built specifically to work with Owens Corning Total Protection system, including the installation lines on their underlayments, guides on Starter Shingles, and the options for ridge cap shingles and appearances.
