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 attic ventilation for Texas?
There seems to be a lot of opinions out there regarding ventilation. None more heated then the topic of ridge vents being used in combination with other attic ventilators. More specifically, Ridge vents & Solar fans.
However, opposite of what you may read from the manufacture specifications or hear from the average contractor, ridge-vents by themselves are struggling to keep up with the intense attic heat that we see in Texas.
67 YEARS OF TRIAL AND ERROR
During the hottest part of the day, your attic space needs desperate help circulating the hot air out of the attic as quickly as possible. After a 20 year experiment using all types of ventilation, HonestRoof.com has found that adding a low out put solar fan “in combination” with ridge vents, to be the perfect, consistent, solution.
Unlike power fans, solar fans do not run for long periods, do not have powerful draws and do not require electricity to operate.
Because it is not a powerful draw (only putting out 800cfm’s (cubic feet per minute), equivalent to a wind turbine) and only runs during direct sunlight they do not interfere with the Ridge-Vents the way a high output power electrical fan would.
These findings took years of paying close attention to customer feed back, performing regular inspections of roofs and attic ventilators that we installed within 10 years and by spending our entire day, 6 days a week, for the last 26 years, either inside an attic or on a roof installing shingles.
WE TRIED THEM ALL
After trying ridge-vents by themselves and adding more and less intake vents, to trying wind turbines and power fans, since adding the solar fans as a combination to the Ridge-Vents we noticed an immediate difference in attic heat build up during extreme temperatures, as did our customers.
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 CONTRIBUTING 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, windows and 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’s.
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 is punctured or chewed through by critters, (reported as a fairly common event) you will not want those 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 someones death. These odors have no smell making it very difficult to detect without the proper warning systems.
Simply making one broad statement regarding proper attic ventilation to be applied 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 our Texas regions. Therefore, further experimentation was needed to find the real ventilation solution for Texas homes. HonestRoof.com stepped up to the challenge.
EXPERIENCE IS EVERYTHING
These types of expert tips 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 however, are based on 67 years of hands on experience actually being bent over on someones roof, in 100 degree temperatures or inside their attic spaces.
After almost a century in business with not one single complaint or negative review ever filed against us for product warranty issues, problems with products or service or faulty work, we believe the proof is in the time.
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.
There are not many of us out there who are actual hands on roof installers with your best interest in mind.
In world of middlemen, who do you trust?
