More homeowners than ever before are focusing on their roofs, and for good reason. It is not unheard of to spend upwards of $10,000 to $15,000 or more on a new roof, and, in some cases, these roofs only last 12 to 15 years. There are a number of maintenance and upkeep tasks, however, that homeowners can undertake to keep their current roof in top condition, such as inspections and routine patching. Another important recommendation that Houston roofing companies make is the need for adequate ventilation.
Most homeowners are unaware of the advantages of good ventilation and its role in making their home more energy efficient. When examining the principles of energy efficiency, for instance, homeowners can see that, in an effort to keep a house warm, a ventilation system will trap too much air inside. These conditions can lead to indoor air pollution that can be just as dangerous as outdoor pollution. While an air filtration system can help purify the air, it can be the source of extra moisture that wreaks havoc on a roof.
The solution is ventilation, and one option for creating good air flow is via a turbine ventilator.
Roofers from Houston Restoration Services of Houston TX would be happy to answer any question you have about storm damage or remodeling.
If a home is poorly ventilated, moisture will become trapped inside the walls, and the plywood on the underside of the roof will begin to buckle and expand. This, in turn, negatively affects the roof, and it can cause cracking in the decking materials. The turbine ventilator allows this moisture to escape, but not heat.
Heat is another issue for the roof, and, in the summer, as temperatures rise over 100 degrees, the attic can get to almost 150 degrees. With all of this water and heat, a good attic ventilation system is certainly necessary. The best attic ventilation systems consist of both and intake and exhaust vents. As the warm air from the attic rises, suction is created at the intake vent. This brings cool air in, and the air removes the heat from the attic and regulates the temperature.
When considering roof ventilation, a homeowner must realize that more is always the best choice, and both roof and attic ventilation should be adopted if possible. There are a number of options, from turbine ventilators to dormer vents. Proper ventilation is the difference between a roof that lasts for several decades and a roof that only lasts 12 to 15 years. Though installing this type of ventilation may be an investment of a couple of hundred dollars, when compared to the thousands a new roof can cost, most homeowners see this as money well spent.
