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!

What is Drip Edge?

Quite simply the Drip Edge is a thin band of flashing, a non-staining, non-rusting galvanized steel which is put around the eaves of your home any time a roofing specialist is replacing the roof on your house. It is a durable material that is employed in a similar fashion as the flashing around fireplaces and skylights.

What is the Purpose of Drip Edge?

The main objective is to avoid moisture from getting behind the eaves or “gutters” that direct rain water away from your home. We do not get a lot of ice dams in Memphis but it DOES happen from time to time and can also be an added layer of protection against that as well. What can happen is as water is shed from your roof, it can actually creep back off the end layer of shingle and find it’s way behind your gutters. If you are lucky, all it does is drip onto the ground. Not idea for the foundation of your home, and it can also be a nuisance when it drips on your sidewalks or your head.

Worse, however, is when the water doesn’t simply drip onto the ground but finds it’s way into your fascia and soffit, and even info the walls. Since the water will always try to flow down with gravity, in many cases we have seen water that was intended to go into a gutter, end up rotting walls, fascia boards, trusses, and even ruin siding and stucco. All because of a lack of a simple and affordable roof upgrade!

How do ContractingPRO roof teams install it?

Skilled roofing companies mount the drip before installing starter shingle or deck base underlayment, during a roof replacement. It is fastened to the roof with galvanized nails or staples every few feet and cut to wrap around the roof and fit tightly to the end of the roof deck and be long enough to direct water into the gutters. After the drip is installed, it is overlapped with a deck base material so that water cannot get under the drip edge, and then a row of starter shingles is installed before finally fastening your new shingles and covering the remainder of your roof deck.

How does it add life to my Roof?

Great Question! Drip Edge when left uninstalled can frequently result in water damage issues that can result in expensive roof repairs or replacement purely for the purpose of remedying the issue. In many cases a roof would likely have lasted 5 more years, the shingles had just began to curl down at the lower edge and allow the water to drip into the fascia and begin damaging the roof. Unfortunately installing drip edge on an old roof will usually do more harm than good, so it is not something that you can do once it is “Too Late” and for this reason:


If you plan on owning your home for 15-25 years and then selling, this simple addition could save you from having to replace a roof once again before you sell your home.
