What Is Roof structure Underlayment?
Roof structure underlayment is a buffer material that’s typically put directly onto your roof structure deck. Depending on how your home was built, the roof structure’s skeleton is composed of rafters or trusses.
The roofing deck, also sometimes called roof structure sheathing, could be:
- Plywood
- OSB,
- Phase sheathing
These boards are fastened into the rafters or trusses to stabilize the rafters or trusses and present a framework on the entire roof structure.
The roofing underlayment is the one that will go on top of this sheathing material. It provides an additional covering of defense against humidity intrusion should any water get beneath your shingles.
Kinds of Roof structure Underlayment
In general, there are three kinds of roofing underlayment: felt, personal-adhered, and man-made. Each possesses its advantages and benefits. The type you decide is determined by your roof specialist’s confidence and local building codes and regulations.
Felt Underlayment
This is among the earliest kinds of roofing underlayment. It is commonly referred to as tar residue papers or felt papers. It is created from a natural and organic mat or papers that have been saturated with asphalt to aid with water resistance.
Felt underlayment is ordinarily available as two standard dumbbells:
15 weight per hundred square feet or No. 15 felt
30 weight per hundred square feet or No. 30 felt
For light assignments, No. 15 felt might be acceptable. Even so, it can do damage easily, and when exposed to the weather during setup, it can take in water and wrinkle.
For house owners who opt for felt underlayment, contractors may recommend No. 30 felt, which is more durable than No. 15 felt. As with any of your underlayment products, it might be employed on many levels to get more safety.
Some roofing contractors commonly use felt underlayment when working with slate or tile shingles. Some may favor self-adhered underlayment. It depends upon the location of the nation.

Personal-adhered underlayments have a sticky back to enable them to adhere to the roof structure deck. This sticky back helps build a water-resistant seal between the roof structure deck and the underlayment. This kind of underlayment was created to shield your roof from problems where water tends to gather or where penetration inside the roof structure deck exists.
Types of these problem-prone regions include:
- Eaves
- Valleys
- Vents
- Chimneys, and
- Skylights
Personal-adhered underlayments are beneficial in areas that get severe winter season conditions.
The top of this particular roofing underlayment surface could have granulated, polyethylene, or polyester resources to supply weather-proof advantages. Additionally, it creates a non-skid surface, designed so it will be less hazardous for roofing contractors to put in, as it can be less complicated so they can move around on.
Synthetic Underlayment
Inside the final decade or so, man-made underlayment has become a well-liked option for house owners. When resources can vary by company, most man-made roofing underlayment comprises some layers of various polymers stitched with each other.
Man-made underlayments typically have several positive aspects
- Tough, long-lasting and damage-proof
- Lighter weight, with more coverage per roll (when compared with most other sorts of underlayment items), minimizing ladder travels
- Protect wandering surface
- Clear, delineated lines and overlap guides for improved setup
- Repels water and is inert to fungus
