When your roof needs work but you are not sure how much, it is important to get that answer. Luckily, with the help of a qualified roofer, you can get the answer you need by completing a few inspections. With these inspections, you will be able to know what problems you have and then determine which repair or replacement options you prefer to do.
A visual inspection is the initial way any roofer determines the quality of a roof. During this inspection, the roofer looks for indicators that a problem exists. However, this process is more detailed than most people realize.
First, the roofer looks for any damaged shingles, which includes cracks, chips or holes that compromise the stability of the roof. Next, they see if any shingles are loose or missing. Unfortunately, loose and missing shingles are the main causes of water damage inside a property, because they allow ice, snow and rain to get into the structure.
After inspecting the outside, most roofers will look at the underside of the roof, which is on the inside of your property. Inspecting this area allows them to locate any additional problems that are not visible from the outside. For example, termite damage and mold growth are two common problems that are difficult to see from the outside of a building. Termites feed on the plywood base, and this same wood is a food source for mold that is caused by excess moisture.
Once the visual inspection is completed, the roofer may use another technique, such as a thermal scan, for identifying weak spots in your roofing system. In the past, if a roofer suspected water damage that may not be visible to the naked eye, they would put pressure on different spots of the roof to see if any sections were soft. Soft spots were an indicator that the roofing materials were saturated with water and they had become weak.
Unfortunately, this method was not always accurate, and some spots were missed. This is where thermal scans come in handy, because the scanner tells the roofer the temperature of each area. Generally, areas that are saturated with water will be cooler than the materials around it.
When water spots are found in time, the roofer can repair these areas. If left untreated, you may have to replace the shingles, water barrier and plywood base of your roof.
Once your roof has been thoroughly inspected, the roofer can tell you how much work needs to be done. After you have this information, you can then determine if you want to repair the issues or if you want to replace all of the materials at one time.
