There are many ways that a roof can become damaged, but the effects of severe storms are often the worst. For instance, high winds can knock over trees and the force from these uprooted plants can fracture the very frame of the building. Even worse, the winds from a storm can rip off shingles and expose the underlying decking to moisture. This becomes a problem because the two most common types of roof decking are engineered materials that do not handle moisture very well. Products such as OSB (oriented strand board) and plywood use portions of wood combined with a resin and cured under extreme pressure. When this material gets wet it can force the need for roof repair services in Ann Arbor, MI.
One problem that occurs when the decking gets wet is swelling. The pressure from the expanding wood can cause the shingles to cup and allow more moisture to enter the roof. Cupping is the result of the center of the shingles being pushed upwards and the tab of the shingle forms an upside down cup. Minor cupping may not be readily visible from the ground, but excessive cupping can be noticed very quickly. If the cupping occurs around roofing details, then it can cause those items to leak as well. Cupping can be prominent around attic vents because the vent is placed through the decking material. Roof repair services in Ann Arbor, MI can repair damaged caulking around roofing details and improve protection.
Asphalt shingles are one of the most common roofing methods around, but not all roofs have a steep pitch. In fact, many commercial structures and certain residences use a roofing method commonly known as a flat roof. The roof is not really flat or it would not be able to shed water. Instead, the structure has a very low slope that is angled so water can shed to one or more of the building’s edges. Flat roofs are typically covered using the BUR (built up roofing) method. This involves multiple layers of roofing felt coated with asphalt and topped with an aggregate such as gravel. BUR can be quickly installed and most repairs are easy to fix.
