Common Problems Caused By Poor Roof Ventilation

Roof VentsFirst Choice Inspectors see a lot of roofs in Chicago and Aurora, Illinois. As inspectors, they look for common problems caused by poor roof ventilation. So, what do they look for?

Inspectors often look at an attic to figure out how the roof ventilation of a house is working well… or not. When a roof is properly vented, the attic allows for airflow such that the air is cooled and moisture is reduced. This is a good thing. Problems occur when the ventilation isn’t working right, and the attic becomes overtly hot and moist. When this occurs, an inspector might notice mold and mildew, saggy or spongy decking, and frost or ice dam formations where they shouldn’t be.

Obviously mold is something no homeowner wants because breathing that stuff in is not good for one’s health. Furthermore, mold messes with the roof sheathing, causing it to wear down. If and when too much moisture ends up in the roof decking, guess what happens… adhesives holding the sheathing together end up dissolving. If you’ve ever walked on roof decking that seemed warped, saggy or even “spongy,” you know that’s not a good thing. Overall, this weakens the roof such that it cannot bear heavy loads as intended.

Poor roof ventilation can also be discovered if and when an inspector notices shingles that seem to be cracking or curling. He or she may look for the loss of granules on the shingles, too.

Have you ever left a car window open in the winter while the car was outside overnight? The next day you discovered that frost had formed inside the car. Imagine that happening inside your attic. When the frost melts there, where does the water go? It ends up dripping into your ceiling– not good. An inspector would want to look for places where wet, cold air could seep into a home. Maybe something as simple as a cracked attic window has been letting in “the weather outside.”

Finally, an inspector looks for ice dams. These form at the edge of the roof creating a barrier preventing water from running off the roof. Ice damming is typically the result of poor roof ventilation.

How Often Should you Replace Your Roof?

Roof Chicago is known as “The Windy City,” and indeed it is. Wind as well as the sometimes brutal winter weather can really take its toll on area roofs.

First Choice Inspectors often do roofing inspections in and around Chicago and Aurora, Illinois. After all, people need good roofs in order to live comfortably, without the harsh elements breaking into their homes through holes and cracks.

Roofs can be made of different materials and are often a product of the time and place when and where they were originally constructed. For instance, some people have wood roofs, while others have stone, metal, rubber or asphalt shingle roofing. First Choice Inspectors often get asked the question, “How often should I replace my roof?” The general answer is once every 20 to 50 years depending on the roofing material used.

For instance, most homes in the U.S. use asphalt shingles. These can last from 10 to 50 years, while most people end up replacing their shingle roofs every 20 years, on average. If you have a wood shake roof, that can last between 20 to 50 years, while tile or metal might last between 50 to 75 years. Some older homes using slate shingles should note that hard slate can last up to 200 years, while soft slate can handle between 50 and 125 years or so.

Oftentimes, how long a roof lasts depends on its thickness and the quality of its installation and materials.

A visual inspection of your roof is a good way to figure out if it needs a couple repairs or if it’s “too far gone” and needs a full replacement. It’s a good idea to have a professional from First Choice Inspectors come take a look at your roof and offer their expert advice on how your roof is doing currently and what challenges might lie ahead. The inspector’s knowledge of roofing can be very helpful to you when determining the answer to the question, “Is it time for a roof replacement?”
