24 May PROPER ATTIC VENTILATION FOR TEXAS, WHO’S RIGHT, WHO’S WRONG?
After receiving a lot of great correspondence recently regarding online pictures posted by HonestRoof.com, one particular question caught our eye. We felt it would make a great topic for our next post.
WHAT IS THE PROPER ROOF ATTIC VENTILATION FOR TEXAS?
There seems to be a lot of opinions out there regarding attic and roof ventilation. None more heated then the topic of ridge vents being used in combination with other attic ventilators. More specifically, Ridge-Venting & Solar Fans.
However, opposite of what you may read from manufacture specifications or hear from the average contractor, ridge-vents by themselves are struggling to keep up with the intense attic heat that we experience in Texas.
THIRTY YEARS OF TRIAL AND ERROR
During the hottest part of the day, your attic space needs desperate help circulating the hot air out of your attic “as quickly as possible”.
After a 30 year experiment using all types of ventilation, HonestRoof.com has found that adding a low out put solar fan “in combination” with ridge-venting, to be the perfect and consistent solution.
Unlike electric power fans:
- “Solar Fans” do not run for long periods of time
- Do not have powerful suctions/air draw.
- Do not require electricity bills to operate.
Because solar fans do not have powerful draws, only drawing approximately 800 cfm (cubic feet of air per minute) and will only run during direct sunlight, they do not interfere with ridge-venting the way a high output power electrical fan would.
Placement, is the key to getting the most of this combination. These findings, took years of paying close attention to customer feed back and performing regular inspections of the roof systems and attic ventilators that we installed within 30 years to determine.
Spending our entire day, 6 days a week, for the last 30 years, either inside an attic or on a roof installing shingles, has afforded us this unique, hands on, learning opportunity that the average contractor simply has not been in business long enough to experience.
When you hire a contractor, hands on experience is what you should be paying for. Simply reading product literature written by ventilator or shingle manufactures or googling how to videos, will not result in what is best for you. That takes years of hands on engagement and first person involvement.
WE TRIED THEM ALL
After starting out with wind turbines, to trying ridge-vents by themselves, to then adding ridge vents with turbines, to then adding more and less intake vents around the soffits of the home, to then going to power fans….since adding “Solar Fans” in combination with “ridge-venting”, (strategically placed in the correct locations), we noticed an immediate difference in attic heat build up during extreme temperatures, as did our customers. These findings were actually in direct opposition of what most manufacture specifications recommended.
Bottom line: less intense attic heat during the hottest part of the day, equals longer shingle life. Better for us. Better for our customers. Better for shingle manufactures.
OTHER POSITIVE FACTORS
Aside from excessive heat decline, we also noticed a decline in attic moisture during the winter. You may have seen or heard the myth of people putting trash bags over wind turbines during the winter. This is an assumption that they are losing heat out of their attic which is causing their homes to become to cool or require excessive heating inside.
The real issue is not the heat you may be losing out of your attic. It is the type and level of attic insulation inside your attic, or what you are losing out of economy grade and/or drafty doors and windows.
DOORS, WINDOW’S & INSULATION
Proper attic insulation and energy efficient doors and windows allows you to keep that precious heat and air “inside the home” without worrying about losing energy out of the attic space or resorting to desperate roof climbing measures.
According to local Dallas Fort Worth insulation and energy efficiency companies, nearly all heating/cooling issues can be directly contributed to inadequate doors and windows. Not attic insulation. Solve that problem, and your heating/cooling issues are over.
LET IT BREATHE
Your attic space needs to be able to breathe, year round. Even in the winter.
Most heavy equipment, such as AC units and furnaces, inside the attic space of most homes, require fresh air to run efficiently and properly for a long period of time without requiring excessive maintenance, repair or replacement. Trash bagging your roof exhaust holes or fully encapsulating your attic space prevents the intake of fresh air which causes maintenance issues and moisture problems, as well as safety concerns from fume build up inside the attic.
HARMFUL AND DEADLY FUME BUILD UP
Another advantage to having some type of actual fanned ventilator on the roof was fume build up prevention. In the event that one of the gas lines inside your attic space is punctured or chewed through by critters, (reported as a fairly common event) you do not want these deadly fumes building up inside your clogged up attic space. The same is to be said about the carbon monoxide poisoning venting from a large number of homes in Dallas/Forth Worth at the hot water tank or furnace flu pipe locations. Any dislodging of these exhaust pipes inside your attic (reported as a common occurrence) and it could result in someone’s death. Carbon monoxide has no smell, making it very difficult to detect without the proper warning systems in place.
WE HAVE THE PROOF
Simply making one broad statement regarding proper attic ventilation and excepting it to apply to all homes in all regions of the U.S. just isn’t practical.
Most parts of the country simply do not experience the type of intense and dry heat that we see in Texas or for as long as we experience it. What works in Ohio, would not apply in Texas. It is not uncommon to see 99 to 100 degree temperatures all the way into October in DFW. Therefore, further experimentation was needed to find the real ventilation solution for Texas homes. HonestRoof.com stepped up to the challenge with the expertise and length of time in business to accomplish it.
EXPERIENCE IS EVERYTHING
Expert tips on this level are the difference between trusting your roof replacement to an actual hands on shingle installer, versus middleman companies or contractors only interested in handling your insurance claim.
Middleman companies, General Contractors and/or insurance claim contractors are basing all of their opinions and recommendations on profit or information they are reading online or at manufacture websites. This is the same information that you can read yourself.
Our opinions, are based on 30 years of “hands on” experience, actually being bent over on someone’s roof, in 100 degree temperatures, or inside their attic spaces, learning and leading from the front.
After 3 decades in business, with hundreds of 5 star customer reviews, the proof has been earned.
Although it may seem as if there is a roofing company on every corner in Dallas Fort Worth. The truth is that 99% of them are simply middlemen or commission sales people, just hoping to take over your insurance claim and cash in on a huge insurance payday.
There are not many of us out here who are actual hands on roof installers with your best interest in mind or with the high level of experience being advertised.
In a world of middlemen, who do you trust?
