It is important to have a roof inspection done when you are considering purchasing a new home, or if you are planning to make an insurance claim. The report will help you understand what work needs to be done and how long it will take to complete. The price and time involved in a roof inspection will depend on several factors, including size, pitch, and number of stories. Fortunately, many roof inspection companies offer a free estimate of the costs of a roof inspection.

Costs of a roof inspection
There are several costs associated with a roof inspection. Depending on the type of inspection and the roof's size, the report may include a list of problems that should be ruled out. The inspector will make a judgment call as to whether the roof is structurally sound. He will also take into account the age of the roof, the materials used, the number of layers, the pitch of the roof, and previous repairs. The process may take anywhere from one to three hours.

A physical inspection is usually performed by a certified contractor who climbs a ladder and examines the roof from the ground. The costs of this type of inspection range from around $150 to $200. Some inspectors even use drones to inspect difficult-to-access roofs. Drone inspections cost anywhere from $150 to $400, depending on the size of the roof. However, these inspections are the most expensive because of the technology involved.

Signs of a sagging roof
There are many signs of a sagging roof and identifying them can help you decide what needs to be done. You can check for a humps, dip, or bow on the flat part of your roof. You can also notice cracks in the exterior walls and uneven support beams. If you notice any of these signs, you should hire a professional roofer to investigate the problem. Ultimately, a sagging roof is a dangerous problem.

A sagging roof is caused by a weak spot in the roofing material or a faulty installation. It can also result from damage to the ceiling joists, which support the weight of the roof. These joists are the support for your roof and may need to be replaced. The best way to fix a sagging roof is to hire a roofer who is trained to diagnose the problem.

Missing or broken shingles
When a missing shingle is found during a roof inspection, it is essential to replace the entire piece rather than just the damaged portion. One missing or broken shingle is not a serious problem, but it could have detrimental effects. Missing shingles can lead to structural damage throughout the home, resulting in higher utility bills. In addition, water can also seep in around the foundation of the property, compromising electrical wiring.

Another important part of your inspection is examining any shingles that are lying on the ground. If you find shingles on the ground, they likely came off the roof in the wind, but they can also come off of the roof in other ways. The shingles may be missing or broken because of a component failure. In some cases, the shingle may be pulled over a fastener, which may indicate improper installation.

Organic growth on the roof
The black streaks on your roof are likely algae. Algae live on the shady sides of the roof and are often found in areas with low levels of sunlight. Because they thrive in such conditions, they spread throughout the roof and degrade its structural integrity. Furthermore, they make shingles crack and wear faster than they should, exposing them to more exposure to sunlight. Hence, it is important to take measures to prevent organic growth on the roof.

When left untreated, organic growths on the roof can lead to mildew and mold. If the growth is severe, it can even cause the roof to rot. Besides that, it can reduce shingle life by destroying the protective oils of the shingles. Fortunately, there are several ways to treat organic growth on the roof. Here are some simple steps to take:
