Every homeowner understands the significance of a solid roof. Not only does it shield your home from the elements, but it also plays a pivotal role in maintaining the structural integrity of the entire building. However, the strength of a roof isn’t solely determined by its outermost layer. Beneath the visible shingles lies a crucial component known as the roofing underlayment. This unsung hero ensures that your roof remains dry and safe from potential moisture damage.
Delving into the Basics: What is Roofing Underlayment?
Roofing underlayment serves as a protective barrier, typically positioned directly on the wooden boards of your roof, commonly referred to as the roof deck. This deck, which might be constructed from materials like plywood or OSB, is fastened directly to the rafters or trusses, providing stability and structure to the entire roofing system. The underlayment is strategically placed atop this sheathing material, offering an added layer of defense against moisture, especially if water manages to seep beneath the shingles.
Exploring the Different Types of Roofing Underlayment
1. Felt Underlayment
One of the most traditional forms of roofing underlayment, felt underlayment, often known as tar paper, is crafted from an organic mat or paper saturated with asphalt. This saturation enhances its resistance to water. While lightweight felt might be suitable for certain projects, it’s prone to tearing and can absorb water if exposed during installation. For those opting for felt, many roofing professionals, including us at Collins & Son Roofing, might suggest a heavier variant for enhanced durability.
2. Self-Adhered Underlayment
Comprising high concentrations of asphalt and rubber polymers, self-adhered underlayment stands out as a water-resistant solution. Its adhesive backing ensures a watertight seal between the roof deck and the underlayment. This variant is particularly beneficial in regions prone to harsh winter conditions, offering protection in areas susceptible to leaks, such as vents and chimneys.
3. Synthetic Underlayment
Gaining popularity over the past decade, synthetic underlayment is composed of multiple layers of diverse polymers woven together. Its benefits are manifold:
- Exceptional durability and resistance to tearing
- Lightweight with extensive coverage per roll
- Provides a secure walking surface for installers
- Water repellent and resistant to mold growth
Why is Roofing Underlayment Indispensable?
The underlayment acts as a secondary shield, offering protection in various scenarios:
- In the event of shingles being torn away by strong winds
- Guarding the roof deck from damage due to ice dams in colder climates
- Protecting the roof from adverse weather during the installation phase
Moreover, local building regulations mandate the inclusion of a roofing underlayment product along with the roof covering. Shingle manufacturers, too, necessitate an underlayment for their warranty provisions.
