Charlotte Roofing: Article About Common Rooftop Underlayment Performance Factors
The underlayment system is vital in determining how well protected the roof's deck will be from all types of moisture damage. It acts as a secondary barrier that catches some of the water that might infiltrate the roof's surface layer of shingles. As such, Charlotte roofing specialists will frequently install these systems to provide homeowners with an even stronger degree of moisture protection over the long term. However, in order to make the most of the installation, it is important for homeowners to think about a few common factors that affect the performance of the system. Knowing what to expect and how to react can be a good way to extend the lifespan of the system itself.
To begin, homeowners will need different types of underlayment installations based on their local climate types. For most installation purposes, determining the right underlayment will depend on two basic categorizations: cold or hot dry climates and cold or hot humid climates. Hot and dry climates will frequently affect bituminous underlayment systems by accelerating the deterioration of the volatile materials within. In humid climates, on the other hand, older underlayment systems will absorb more moisture, which in turn will cause the substrate to expand and become brittle.
Sometimes the design of the roof system itself will also determine how effectively the system functions.

Many common roof designs are made to help shed runoff quickly, while many design features will also have sections that can trap runoff. When that happens, the underlayment is exposed to more moisture than it can readily handle. This results in long-term damage to the system itself, which can open up the roof's deck to even more moisture problems.
Sometimes the roof covering material may also cause problems to the rest of the installation. Manufacturers will frequently develop underlayment systems that are designed to be matched with specific roof covering materials. The use of incompatible materials may result in chemical deterioration issues over the course of the roofing system's life. This can greatly contribute to long-term damage on the rooftop.
Finally, homeowners should make sure that the underlayment system itself is properly installed and not damaged. One of the most important things that homeowners can do is regularly inspect their attics to see if there are signs of moisture damage there. Wet spots and leaks can indicate that there is a certain section of the underlayment that is experiencing damage more heavily than the rest of the system, which can cause uneven damage on the roof's surface.
