A regular roof inspection is a necessary part of roof maintenance. The inspection can reveal problematic parts of the roof so you can repair them before the damage expands. Below are some signs that indicate potential roof problems.
Roofing materials lose their original color over time. Exposure to weather elements, such as precipitation and rainfall, contributes to discoloration. However, you should be worried if you have discolored patches on the roof. Discoloration on a relatively new roof is also suspect.
For one, discoloration might mean roof debris, which encourages moisture retention, rot, and pest infestation. Discolored patches on a new roof might mean defective roofing materials. Get a professional roofing contractor for a professional diagnosis.
All parts of the roof are necessary — roofing contractors don't include unnecessary things on the roof. Thus, you should suspect something is wrong if some roof parts are missing. For example, you need a professional inspection if you spot:
You should know the causes of the loss, related damages, and possible solutions. You should also know how to prevent the damage from reoccurring in the future. A roofing contractor can help you with all these and more.
Roofing contractors install materials or parts in specific ways and places for roof efficiency and integrity. For example, a gutter with the wrong pitch can allow water to back up under the roof. A sagging roofline might mean your house has a sinking foundation, the roof is structurally weak, or the exterior walls are structurally compromised.
A large piece of debris on the roof is also a cause of concern. For example, a large tree branch or tree on the roof means your roof has probably suffered mechanical damage. Falling trees or branches can puncture roof membranes, disconnect gutters, and dislodge or crack shingles.
Ice dams occur when the snow melts but then refreezes on the lower roof sections. The ice forms a dam that blocks water from flowing off the roof. The water behind the dam deteriorates your roofing materials and can penetrate the house.
An ice dam indicates a non-uniform surface roof temperature. Non-uniform roof temperature usually occurs on poorly ventilated and insulated roofs. Your roofing contractor will inspect your roof and diagnose the damage.
