Any roofing project starts with an initial inspection. When you decide that you want to install a new roof for your home, your contractor will likely go through an inspection process early on. This process will help the contractor understand the current state of your roof and its underlying infrastructure, and it will allow them to determine how to go forward with the project. In this article, we’re going to go over what the roofing inspection process consists of.
1. Broken or Missing Shingles
Asphalt shingles are currently the most commonly used type, being a part of 80% of residential roofs. However, as they age, they will become brittle, and after one or two decades of wear and tear, they generally start to crack and break down. Add some wind to the equation, and soon enough, you may have pieces that are torn off the roof during a storm. As such, this will be one of the first issues that your contractor will check for during the inspection process. If your shingles break off much sooner than the timeframe above, it may also be a sign of a poor installation.
2. Mold, Mildew, or Moss
The contractor will then check for mold, mildew, or moss. Not only can these patches be an eyesore, they also damage the shingles and the underlayment on your roof. These patches will develop over long periods of time with the right moisture, and as they grow, they can create lumps that displace shingles and interfere with the water runoff.
3. Issues with Ventilation
Proper ventilation is essential for any roof. Without it, hot air gets trapped inside the attic during the summer, which then heats up the roof’s deck and causes the shingles to become brittle. During winter, ice will start to form into dams in the gutters, which generates moisture beneath the shingles and rots the roof deck. As such, your contractor will pay special attention to ventilation features such as exhaust vents, ease vents, and ridge vents.
4. Buckles, Blisters or Ripples
When buckles, blisters, or ripples start to show up on a roof, they indicate several underlying issues — this can include old shingles, a wet underlayment, too many layers of shingles, damage to the sheathing, improper ventilation, or inadequate ventilation. These blemishes occur naturally as the shingles get older, but when they become visible from a quick inspection on the ground, they are a clear sign that you should call your West Chicago roofing contractor.
5. Several Layers of Shingles
Every extra layer of shingles installed puts pressure on the structure of the roof. This can lead to damage over time, which may not always be visible. Multiple layers can also lead to ventilation issues. However, they can be a cost-effective option to replacing the entire roof. As such, many homeowners choose to go with this option. You also have the issue of telegraphing when adding multiple layers, where the top layer will conform to the bottom layer over time, taking the shape of any low spots or humps that have been formed there. In order to properly address any issues that you may have with your roof, your contractor will check to see how many layers of shingles have been installed.
