Importance of proper insulation and ventilation in residential roofing

Asphalt shingles are a go-to roofing material because of their popularity on roofing market today. They owe their popularity to the facts that they are durable, easily installed and affordable. When you decide that you will install a brand new asphalt shingle roofing system, thing you probably think about the most is which brand to choose and which colors are available. However, a skilled roofing professional will consider two more things that are vital for any roofing system – insulation and ventilation. Asphalt shingles are on the first line of defense against
outside weather elements . But that is not enough; roofing system still needs to provide you with protection against structural damage, mildew, high energy bills and mold.This is where insulation and ventilation come in.

Insulation and Ventilation


Constant and consistent airflow is allowed and provided by ventilation. All that streaming air that runs under your asphalt shingles prevents the buildup of cold, moisture and heat under your roofing system. Your attic can become too hot during summer if your ventilation is poor. All that heat coming from attic can easily damage your shingles and shorten their expected lifespan. On the other hand, if you have poor ventilation during the cold months it can lead to building up of cold air in your attic which in turn can result in rising levels of moisture. Moisture is a breeding ground for dry rot, mildew, and mold which can cause various problems to your insulation, shingles and roof support structure. That is why it is vital to properly ventilate your roofing system during installation. That way you can avoid having various problems and costly repairs to make.


Insulation is an element of an asphalt roofing system which you should not overlook during the installation because if not done correctly, insulation can cause many problems for you. If your home is not properly insulated, you will have problems with extreme temperatures. Poor insulation is a common thing for older homes which were built back in time when building codes didn’t ask for that much insulation compared to today’s codes. Poorly insulated attic can be a nightmare to every homeowner because the need for heating and cooling systems will be much higher. It is clear that asphalt shingles roofing system requires proper attic insulation and ventilation, however, meeting these requirements isn’t always that easy and straightforward.You should ask a professional roofing contractor what type and amount of insulation and ventilation your existing roofing systems needs. It is important to be optimal.

What can your roofing contractor do?

The first thing your contractor will do is to find out what is blocking the airflow through your attic. The most common problem lies in insulation or some other material blocking the opening of the vent, and your roofing contractor will remove that obstruction. Sometimes, poor ventilation is caused by an inadequate intake or exhaust of air or even bad placement of the vents.
