What is Roofing Underlayment?
Roofing underlayment is a water-resistant or waterproof barrier installed directly onto the entire roof deck beneath the final roofing material. Acting as a crucial secondary layer of protection, it prevents water infiltration if shingles or other roofing materials are damaged by severe weather or age. In Maryland’s varied climate, proper underlayment installation is essential for safeguarding homes against heavy snowfall, intense storms, and wind-driven rain.
Beyond moisture protection, underlayment also provides a smooth surface for shingle installation, temporary weather protection during roofing projects, and enhanced resistance to UV exposure and foot traffic. Modern synthetic materials have largely replaced older felt-based options, offering greater durability and ease of installation. At Thunder Bay Roofing, our roofers ensure that every underlayment is chosen and installed to meet the specific weather challenges faced by Maryland homeowners, maximizing roof performance and longevity.
Benefits of Roof Underlayment
Some of the many benefits of roof underlayment include the following:
Superior Water Protection
Quality underlayment creates an impermeable barrier that prevents water from reaching your roof deck, even if shingles are damaged or displaced. This protection is especially crucial in Maryland’s climate, where ice dams and severe storms can compromise your primary roofing material. However, if underlayment is left exposed to the elements, its effectiveness can be compromised, increasing the risk of water infiltration and roof damage.
Enhanced Wind Resistance
Modern synthetic underlayments provide excellent resistance to wind-driven rain and uplift forces. This is particularly important for homes in Upper Marlboro, Fort Washington, and surrounding areas that experience high winds during storms.
Temperature Regulation
Underlayment helps regulate attic temperatures by providing an additional insulation layer. This can reduce energy costs and prevent ice dam formation during Maryland’s cold winter months.
Extended Roof Life
By protecting the roof deck from moisture, underlayment prevents rot, mold growth, and structural damage that can significantly reduce your roof’s lifespan. This roof protection is invaluable for Maryland homeowners looking to maximize their roofing investment.
Additionally, some underlayment products come with a lifetime warranty, offering long-term peace of mind for homeowners.
Types of Roof Underlayment
Asphalt-Saturated Felt
Traditional felt underlayment remains a popular choice for many Maryland roofing projects. Available in 15-pound and 30-pound weights, felt provides reliable water resistance at an economical price. While heavier than synthetic alternatives, felt underlayment offers proven performance and is suitable for most residential applications for homeowners in Edgewater, Timonium, and surrounding communities.
Synthetic Underlayment
Modern synthetic underlayment materials offer superior performance characteristics compared to traditional felt. These advanced materials are lighter, stronger, and more resistant to tearing and UV exposure. Synthetic underlayment is ideal for Maryland homes that require enhanced protection from severe weather conditions and provides excellent walkability during installation.
Rubberized Asphalt
Self-adhering rubberized asphalt underlayment provides the highest level of water protection available. This premium option is particularly beneficial for low-slope roofs, valleys, and areas prone to ice dam formation. While more expensive than other options, rubberized asphalt offers unmatched performance for critical applications.
Peel-and-Stick Membranes
Peel-and-stick membranes create a completely waterproof seal and are excellent for vulnerable areas like eaves, valleys, and penetrations. Thunder Bay Roofing often recommends peel-and-stick membranes for Maryland homes in areas with heavy snow loads or frequent freeze-thaw cycles.
Underlayment Selection for Different Roofing Materials
Choosing the right underlayment depends on your roof covering and slope. Different roofing products may require specific types of underlayment and fastening methods, such as nails, to ensure proper installation and performance. Here’s how selection varies by material:
- Asphalt Shingles: The most common roofing material in Maryland, asphalt shingles typically pair well with either #15 or #30 asphalt-saturated felt or modern synthetic underlayments. Synthetic options offer superior tear resistance and longer exposure times. When installing underlayment for asphalt shingles, it’s important to use the correct nails to secure the material and maintain wind resistance.
- Metal Roofing: Metal roofs require underlayments that can withstand high temperatures, such as high-temperature ice and water shields or advanced synthetics. Avoid traditional felt, as it can degrade under metal’s heat. Proper installation includes using the appropriate nails or fasteners recommended for these roofing products.
- Tile and Slate Roofing: These heavy, long-lasting materials demand robust underlayment. Double layers of #30 felt or premium synthetics are standard. Self-adhering membranes are recommended in valleys and eaves for extra protection. Always use the correct nails to secure underlayment beneath tile and slate roofing products for durability.
- Flat and Low-Slope Roofs: Specialized self-adhered or modified bitumen underlayments are often required, as water drainage is slower and the risk of leaks is higher. For these roofing products, follow the manufacturer’s guidelines for nails or fasteners to ensure a watertight seal.
- Steep-Slope Roofs: Standard synthetic or felt underlayment is typically sufficient, but always confirm with your manufacturer for compatibility. Use the recommended nails to properly fasten the underlayment for these roofing products.
Building Codes and Regulatory Requirements for Roof Underlayment
When installing roof underlayment, compliance with local and national building codes is essential for safety and legal reasons. In Maryland, as in most states, the International Residential Code (IRC) and International Building Code (IBC) set the standards for roof underlayment installation.
Key Requirements:
- Minimum Layers: Most codes require at least one layer of underlayment for standard sloped roofs. For low-slope roofs (less than 4:12 pitch), two layers or a specific self-adhered membrane may be required.
- Overlap and Fastening: Underlayment sheets should overlap by at least two inches horizontally and 6 inches at end laps. Fasteners must be corrosion-resistant and spaced according to the manufacturer and code requirements.
- Ice and Water Shield: In areas prone to ice dams, such as northern Maryland, codes often require a self-adhering ice and water barrier at eaves, extending at least 24 inches inside the exterior wall line.
- Fire Ratings: Certain jurisdictions require underlayments with a Class A fire rating, especially in wildfire-prone areas.
- Materials and Techniques: Using the right materials and techniques for every job is crucial to ensure compliance and long-term durability.
Why Roof Underlayment Compliance Matters
Following code ensures your roof passes inspection, maintains warranty coverage, and meets insurance requirements. A properly completed job not only meets code but also ensures long-term roof performance and reliability. Always check with your local building department for the latest regulations before starting your project.

Roof Underlayment Maintenance
While underlayment is designed to be a long-lasting component of your roofing system, periodic inspection and maintenance help ensure continued performance. Regular maintenance is especially important after harsh seasons, such as winter or heavy rain periods, as each season can present unique challenges that impact your roof. Thunder Bay Roofing recommends annual roof inspections for residential and business properties that include underlayment assessment, particularly after severe weather events or when other roofing work is performed.
Signs that your underlayment may need attention include visible sagging, water stains in the attic, or damaged shingles that could have compromised the underlying barrier. Our maintenance services include thorough inspections, minor repairs, and recommendations for preventive measures that protect your investment.
Proper attic ventilation plays a crucial role in underlayment longevity by preventing moisture buildup and temperature extremes. Our team can assess your ventilation system and recommend improvements that enhance underlayment performance and extend its service life.
