We recently discussed an array of products you can use for attic exhaust and intake to obtain a balanced roof ventilation system. One topic we covered lightly, that we wanted to go into more detail about, was the commonly found problem of short-circuiting your roof ventilation system. Below you will find a perfect example of a roof that will experience a higher level of degradation than normal.
Short-Circuit Ventilation System
About two weeks ago, the marketing and roof consultant team attended a seminar on attic ventilation giving us additional information and knowledge about the subject to share with our clients. Today, we’d like to take the opportunity to share with you the pros and cons of different exhaust and intake products that can be used to complete your roof ventilation system.
We’ve seen quite several different techniques for roof ventilation across the Greater Portland area including artistic roof ventilation, roof ventilation overload, and the use of additional can vents.
During an inspection of a Beaverton Condominium complex, we noticed the use of can vents placed low on the roof for intake instead of having intake cuts below the roof line.
We take roof ventilation seriously because of the ‘bad and ugly’ roofs we come across on a daily basis. Today’s post features an image of a homeowner’s ‘ugly’ roof that’s rotting from the inside out. Aside from this roof needing to be replaced prior to the expiration of the warranty, the attic has a potential mold issue which will certainly cause additional family havoc.
If you didn’t get a chance to read our post about roofing material
, and paying for a disheveled composition roof, than the roof pictured below may appear to have a serious roof ventilation issue. One of the first signs of a improperly ventilated roof is curling shingles which it appears to be the case for this roof.
We’ re constantly preaching to our clients the importance of roof ventilation. Energy costs and the degradation of your roof can vary based on your roof ventilation. Some homeowners have a roof ventilation overload and some homeowners have an under-ventilated roof.
Installing a power fan is a great way to add the necessary roof ventilation you need. However, the power fan needs to be installed properly and the photo below is a great example of an incorrect power fan installation.
When home communities are built, the builder has a vision and theme he is trying to display through each individual house and the overall community. We typically find faulty roof and gutter installations due to the builder’s desire to complete the project as fast as possible. If every builder created a bullet proof house, it would cost you less to maintain your home, but the job would take longer and the builder would make less profit. Instead, you find roof’s like the one below with a very ‘artistic’ looking roof ventilation system.
At Roof Life of Oregon, we’re constantly observing roof ventilation issues that eventually lead to premature roof failure. Some of the problems and results we’ve examined here on the blog include curling roof shingles and too many can vents. On a recent day out in the field, we saw a home with a roof ventilation overload that we have not recently discussed on the blog.
