There are a few things a property owner in Frederick can count on, and they include bad weather and damages to the building and its roof. One cause of roofing issues is moisture under the shingles. Moisture can occur for various reasons such as dried caulking around vents or flashing and aging shingles that crack or curl. Once the moisture gets trapped, it can freeze during those cold winter nights, and this results in even more problems. Freezing water expands and this can cause the shingles to be pulled further away from the roof. The expansion also makes room for additional water and the need for an expert Roofing Contractor in Frederick MD.
Eliminating water damage to a roof can be an extensive job because the contractor needs to locate any damaged supporting materials such as decking or rafters. Roof decking is vital because it spreads out the weight of the material that protects the structure. There are two common types of decking, and both of them are engineered materials. Plywood is one of them, and this type of decking can be extremely reliable. The other is OSB (oriented strand board), which is a more economical material. Unfortunately, engineered lumber can degrade once it is exposed to water. For example, the wet wood will begin to swell, and this can cause any shingles over the swollen area to cup. Cupping exposes even more of the roof to moisture problems.
A great Roofing Contractor in Frederick MD can handle all kinds of roofing tasks. One common type of roofing used in commercial installations is the flat or low-sloped roof. This is a roof with an angle so low that it appears to be flat. The typical flat roof uses a roofing technique known as BUR (built-up roofing). This is a combination of roofing felt and asphalt that is applied in multiple layers and covered with a ballast of gravel or a similar aggregate. One of the benefits of BUR is quick repairs. Minor damages can be quickly patched and larger issues can be fixed by placing another layer over the roof. Roofing details on a flat roof will need to be sealed with an asphalt caulking to reduce the chance of water damage. Learn more about roofing solutions from the experts at Politz Enterprises Inc.
