Charlotte Roofing: Article About Underlayment Types
When most people spot a leak in their ceiling, they automatically assume that there is a problem with their shingles. While missing or broken shingles can lead to leaks, there is a high chance that there is a problem with the underlayment as well. Cracked shingles can easily splinter and scratch or break through the underlayment, which reduces its ability to keep water off the deck. Any damage to the underlayment may allow enough water through so that it rots the deck. Contractors will then need to either completely replace the deck or replace multiple parts of that deck. If the underlayment on a roof shows any type of damage, Charlotte roofing companies often recommend that customers replace the underlayment with one of the newer varieties available on the market.
Some think that the most common varieties of underlayment are rolled or paper options. These terms refer to the way in which the material is mass marketed and do not describe any special features the products may have. Rolled types are generally more popular because the rolled version gives contractors more control over how they use and install the underlayment. They can carry the rolls across the roof and cut through the underlayment to cover a large portion of the roof with a single piece. The paper version, on the other hand, comes in large sheets that contractors will need to lay down on the roof one piece at a time.

The more common varieties of roofing underlayment include tar paper, felt paper and rubber. Tar paper is a simple type of paper coated with a thin layer of coal tar. Though older homes may feature an underlayment made entirely from coal tar, contractors seldom do this today because the coal tar adds too much weight to the home and may be susceptible to fire damage. A smaller coating of tar added to lightweight pieces of paper provides the moisture protection that homes need without weighing down the roof.
Felt paper, sometimes called asphalt felt paper or simply asphalt paper, is another option. This type of product makes use of thin sheets of felt with asphalt added to the surface. This creates a rougher surface that prevents standing water from accumulating on the rooftop. Felt paper works in the same way as the granules found on shingles do to keep water moving off a roof. Homeowners who are concerned about water damage may find that rubber is a better option. As rubber is flexible and lightweight, it completely covers the roof, blocks out moisture and has a smooth surface that helps water roll off the building.
