Importance of Proper Roof Ventilation

Replacing a home’s roof is the most important home improvement project homeowners have to navigate. It is more than picking which materials, color, and even the right roofing company for the job. Many homeowners rush through a roof replacement too quickly and never consider the importance of roof ventilation. The easiest way to make sure roof ventilation is set up properly is to hire a professional and reputable roofing contractor.

Why Does Roof Ventilation Matter?

Climate and weather vary depending on where you live. In South Central Pennsylvania and Northern Maryland, homeowners experience extreme temperatures in the summer along with freezing temperatures and snow in the winter.

The right ventilation system lets cool air from outside in while also letting hot air out of your attic. If hot summer air can’t escape, moisture builds up causing damage inside your home. Another problem we see during the winter months occurs after it snows. If a roof has bad ventilation, the hot air trapped inside causes snow to prematurely melt before it refreezes as an icicle on the edge of your roof. This means the moisture from the snow can seep under roof shingles and into your attic causing mildew, mold, and rotting.

Signs Your Roof Ventilation isn’t Right

Skipping proper roof ventilation during a roof installation or roof replacement can cause a 30 year roof to only last 5-6 years before the damage is too great to ignore. Whether you are ready to replace your roof or just curious about your home’s ventilation, it is important that you know what signs to look for so you can be proactive.

1.       Mold on the Roof

If your roof looks like it has dirty spots, it might be mold. If the mold is ignored for an extensive period of time, it can ruin the shingles, and mold spores can start to grow in your attic. Once mold grows inside your home, the effects are damaging to your house construction and your family’s health.

2.       Attic Leaks

Water can leak into your attic for a long time without you ever seeing it. This happens most often after storms, downpours, or snow. If the flashing or underlayment isn’t in its best state, it allows for water to leak in causing silent damage.

3.       Expensive Energy Bills

If your heating and cooling bills are significantly high or start to increase for no reason, it makes sense to have a roof inspection. When air isn’t able to flow in and out, hot air stays and pushes down on your home making the air conditioning work twice as hard to keep your home cool.

4.       Ceiling Stains

Stains on the ceiling are a sign of water or moisture in your attic. They can be caused by mold, mildew, or a consistent roof leak.

5.       Peeling Paint

When roof ventilation fails, unwanted moisture stays confined in your home. Eventually, that moisture causes paint on the ceilings or walls to bubble and peel.

6.       Clean Roof after it Snows

Look at your roof after it snows. If it isn’t still snow covered, the hot air in the attic may be causing it to prematurely melt.
