How Attic Ventilation & Insulation Affect Roof Integrity
The Role of Attic Ventilation During Arizona’s Summer
For optimum performance, your roof needs more than just quality shingles and flashing. An efficient roof requires a complete roofing system. This means more than just what you can see on the outside – proper attic ventilation and insulation are crucial to the integrity of your roof.
When correctly installed by a Phoenix roofing company near me;, your roof and attic systems will work together to keep the temperature inside your home at a comfortable range, allowing you to save money on heating and cooling bills, and will also prevent the buildup of harmful moisture inside your home.
Attic Ventilation and Insulation: The Key to Roof Integrity
The combination of quality attic insulation and a properly functioning ventilation system will protect your home by keeping moisture and excessive heat out of your home. When these systems are working as intended, you’ll be able to maintain comfortable temperatures inside your home and attic all year round.
When an attic is not correctly vented and insulated, your attic will begin to trap heat and moisture. If left untreated, your home will end up with significant damage, which can include:
- A sagging roof as the moisture in the attic compromises the wood structure of the home
- Nail heads on your roof can rust and weaken your shingles
- Roofing materials may fail prematurely, forcing you to replace your roof sooner than expected
- Harmful mold, mildew, and fungi can grow inside your home and cause severe health issues, requiring expensive and inconvenient remediation
- Your home may develop interior damage from the excessive moisture
How Do Attic Ventilation Systems Work?
Attic ventilation systems work by removing excess moisture and stagnant air from the home to the outside, while maintaining the cool air inside the home. When your Phoenix roofing company installs attic ventilation, your air conditioning unit can keep the air inside your home at a comfortable temperature, with safe levels of moisture. A properly vented attic will allow natural air flow and prevent excessive heat buildup.
The ABCs of ventilation can help you understand how attic ventilation systems work.
A: Ample Amount
You want to get enough ventilation and air flow in your attic. Your Phoenix residential roofer can help you understand how much ventilation your local building codes will require for homes of your size.
To function properly, your ventilation system needs a balance intake and exhaust vents. For most homes, this will be an equal number of each. Exhaust vents will be installed toward the top of your roof to help air diffuse out of the attic and avoid negative pressure buildup. Intake vents are usually installed lower on the roof slope or in soffits.
It’s important for the air pressure in your attic to maintain balance, or your attic will suck air from the inside of your home through any available crack, such as framing joints or light fixtures, which means that you’ll be running your air conditioner to cool your attic’s air.
C: Control Air Flow
Lastly, air flow within the attic needs to be controlled so that the cool air in the rest of the home isn’t being sucked into the attic. Air sealing saves you money on your AC bills and helps keep your home comfortable. This is accomplished by a thick layer of insulation, which is critical to keep your home cool during the summer.
The Role of Attic Insulation
Air is always moving; hotter air finds it way to the cooler areas until the temperature in the whole home is the same. But no one wants the summer heat from their attic moving down into the air conditioned rooms. A quality insulation installation will effectively block this air movement between your attic and living spaces, so your rooms stay cool and comfortable. A contractor can help you check for air leaks in your home that may be encouraging the cooled air in your home to be wasted in the attic. These leaks are common around soffits, in recessed lighting boxes, in electrical boxes, and joints where ceilings and walls meet.
Arizona homeowners understand the expense of keeping a home cool in our hot summers. When your roof is functioning correctly with the right amounts of insulation and a quality ventilation system installed by Phoenix roof repair, you can avoid excessive cooling costs and feel good about your roof’s integrity.
