When a homeowner wants to ensure their home’s roof is in good condition they are often more focused on the outside and never consider what problems could be happening within. One essential part of the roof’s and home’s health is the attic. The attic requires proper installation and ventilation. Today Big Ike’s Roofing Co would like to focus on the importance of proper attic ventilation and what is looked for during an attic ventilation inspection and what is on the checklist that professional roofers look for.
Why Attic Insulation is Important
The attic requires ventilation and air circulation to improve the overall condition of the roof. The roof rests on the roof framing which is visible inside the attic. The attic is also insulated to help keep the heat or cold of the season from affecting the inside temperature of the home. Ventilation is important for a number of reasons. During the various seasons the attic can be affect by humidity or even frost. When moisture gets trapped or builds up inside the attic, mold, and mildew can develop. The wood can even begin to rot due to moisture. If the roof frame has become too weak due to moisture damage the entire roof can collapse. The attic insulation is also compromised and even your home’s interior air. If you have the furnace installed in the attic, which is common, it pulls the air from inside the attic. If mold spores are present they can be circulated throughout the home. If the attic is properly ventilated it can prevent frost or humidity from building up inside the attic and help prevent moisture damage to your roof’s framing and the attic insulation.
Attic Ventilation Inspection Checklist
When the attic’s ventilation is being inspected there are five key points that the ventilation must meet to ensure proper air circulation.
Attic Ventilation Balance – The exhaust vents which are located on the roof’s ridges, and the intake vents which are located near the soffits, must be properly balanced. Meaning they are one for one in size. It is surprising to learn that many homes have improper or inadequate intake vents, which often require additional intake vents to be installed.
Proper Roof Vent Dimensions – The next common problem is that vents are not the proper size. You may have one for one exhaust and intake vents, but they are not the proper size for the attic space. All too often the vent sizes are too small which restricts the air flow needed to properly ventilate the attic. This of course leads to the need for larger vent installation.
Are There Attic Baffles – Many homes are built and insulation is installed without baffles. Baffles are rather essential as they help prevent the soffit vents from becoming blocked by the attic insulation. If your insulation has covered or blocked the soffit vent, then there is no proper air flow. If you had your attic inspected and it revealed there are no baffles consider having some installed.
Presence of Excessive Moisture & Condensation – As moisture destroys the roof framing you can expect that during an attic inspection the attic will be checked for moisture damage. This can indicate if there is a problem in the attic ventilation.
