Roof Ventilation: What’s Involved in an Attic Inspection?
You may think that if the roof is not leaking and seems to be holding together, nothing is wrong. The reality is many small problems could be hidden away and ongoing, especially if the ventilation system is not working properly. This is why a thorough inspection of your roof and attic is very important before moving on to repairs or replacement.
Hire a Professional
While it may seem like a simple job, attic inspection is best left to a professional. No matter how long you have owned and lived in a home, you may not know all of the places to look for possible problems. A professional has been trained to look in every corner and crevice of an attic and will provide better results.
Attic Inspection Process
When a contractor comes in to inspect your attic, the first thing to be checked is the air flow. The root of many attic and roof problems starts with an improper flow of air. Other factors in an inspection include the following:
• Does the ventilation system match up with the roof design? Roof designs can vary greatly between houses. Whether it is mansard, shed, hip or gable, it will require the right venting to maximize the air flow.
• What is the number of attics? Large homes can have more than one attic, and it is possible for them to be connected. Whether the attic space is separated or shared, ventilation is of utmost importance.
• Is there anything blocking the attic vents? Most attics are used as a storage space by the homeowner. Over time, this space can become crowded to the point where objects are blocking the vents, which will eventually cause problems.
• What is the ratio of air exchange? The inspector will calculate this by measuring the square footage of the attic. This number will also determine if the current ventilation system is adequate.
• Is the attic insulated? An insulated attic will keep a home cool in the summer and warmer in the winter. The homeowner will have lower energy costs.
• Is there any mold, mildew or rust present? This is crucial because the presence of these can indicate poor or obstructed ventilation or possibly a roof leak. Mold is a slow-moving problem that can spread into other parts of the home, causing odors, damage and health problems.
Most roof and attic problems are preventable. To avoid expensive repairs, you should have your attic inspected at least once per year by a professional company.
