All roofing materials deteriorate from exposure to the weather at rates determined largely by the kind of material and the conditions of exposure. In general, inorganic roofing materials tend to deteriorate less rapidly from exposure than organic roofing materials. All types of roofing materials may be damaged by hail. Exposure to air pollutants and industrial or salt-laden atmospheres may accelerate the deterioration process of some roofing materials. No matter the cause of roof damage, roof repair is necessary in order to prevent future damage and reduce cost.
Roofing materials are subject to damage from strong winds and flying debris. Generally, roofs are not designed to withstand winds of hurricane and tornado intensity. However, roofs may also be damaged by winds of moderate intensity, with gusts that may reach 50 to 75 miles per hour. The primary cause of wind damage is from the partial vacuum created by wind blowing over the edge of the roof. Nature tries to neutralize the low-pressure area by bringing in air from a higher pressure area, usually from inside the building. This air pushes up on the bottom side of the roof assembly and, over time, loosens fasteners and breaks the adhesion making the roof susceptible to damage from the next moderate or strong wind. To counteract the effects of wind uplift forces, the roofing and insulation should be adequately fastened to the roof deck, and a securely-fastened perimeter detail should be provided. We provide roof repair services to correct the effects of wind uplift and ensure that each part of your roof is securely fastened.
Troublesome and costly roofing problems are often the result of a faulty initial design of the roof system. Design deficiencies are costly to correct and usually can only be corrected during a roof replacement. Unless design deficiencies are discovered and corrected during roof repair or re-roofing, these deficiencies will most likely cause more problems in the future.
The function of flashings is to provide a watertight junction between roofing materials and roof projections or other parts of the structure, and between roof sections. Flashings should be designed to furnish service for at least as long as the materials used in the field of the roof. Flashings are the most vulnerable part of any roof. The importance of maintaining them with roof repair cannot be overemphasized. A roof repair for flashing failure involves working to repair existing flashing or install new flashing that will properly protect the roof’s structure and the interior from leaking.
