Get to know these polymer problems before choosing an underlayment
Synthetic roof underlayment problems often stem from moisture buildup, which occurs when your underlayment blocks water from escaping and leads to mold.
Your synthetic underlayment costs $0.10 to $0.75 per square foot for materials, with pricing depending on quality, thickness, and adhesion type.
UV damage breaks down your synthetic underlayment when exposed to extreme temperatures and sunlight, causing brittleness, cracks, and blisters over time.
Hiring a local insulation company provides reliable guidance on proper installation and ventilation setup, helping your roof stay protected from moisture and damage.
Tucked between your roof deck and roofing materials, roof underlayment plays a critical role in your roof's anatomy. Felt, rubber, and synthetic roof underlayment are your most common options, and each has ups and downs. Common synthetic roof underlayment problems often stem from incorrect installation, poor design, or the cost of underlayment replacement down the line.
Synthetic underlayment's ability to protect against moisture is both a perk and a problem. Made of polyethylene or polypropylene, the underlayment naturally acts as a barrier to a roof's largest threats—water and humidity. While synthetic materials can keep water from reaching your roof deck, moisture from your home or water that breaks through small roof cracks can lead to mold, algae, and pests.
This type of underlayment also cannot absorb water as felt does, which is its top competitor. Installing proper roof ventilation is crucial to ensuring proper airflow, as does proper installation around the eaves and flashing.
Synthetic roof underlayment is highly durable compared to other options, but it still struggles with extreme temperatures and sun exposure. If you live in an area with ample sunshine throughout the year and minimal shade, UV rays can slowly break down the structure of your synthetic roof underlayment, releasing Volatile Organic Compounds (VOCs) in the process. Brittleness, cracks, and blisters can expose your roof deck and top floor to insulation and water damage.
Protect against UV damage and similar synthetic roof underlayment problems by ensuring proper installation by an insulation professional. Exposure to high temperatures before installation, for example, should be avoided. If you live in a sun-drenched state like Nevada or Florida, it's best to talk with your roofer about other types of underlayment.
Whenever you're planning to restore or replace your roof, it's best to hire a roofing inspector knowledgeable about local building codes. Synthetic roof underlayment is also not ideal for all types of roofs. Some areas outlaw synthetic underlayments due to moisture trapping, which can lead to structural issues and mold. Additionally, since synthetic underlayment releases VOCs as it breaks down, it’s not ideal under some major types of roofing materials.
The majority of synthetic roof underlayment problems occur during installation. Always hire an experienced roofing contractor or an insulation professional near you to handle and secure the underlayment properly. Professional installation teams will use the appropriate roofing nails, fasteners, and flashing around the edges of the underlayment to ensure both its seal and its durability. Work with a contractor familiar with purchasing high-quality underlayment and its unique installation requirements.
Some forms of synthetic roof underlayment come with a self-adhering backing for easier installation. While helpful for contractors upfront, the strong adhesive can make things very tricky when it's time to replace the underlayment. The residue from the underlayment can damage the roof deck and even the roofing material, leading to higher-than-intended costs in the long run.
Never cut corners when choosing a synthetic underlayment for your roof. Lower-quality materials can split when exposed to heat and extreme cold, leading to delamination. Thickers and higher-quality underlayment also provide better insulation and protection against roof leaks. On average, synthetic roof underlayment lasts between 10 and 40 years when properly installed and maintained.
Synthetic roof underlayment costs between $0.10 and $0.75 per square foot, depending on its quality, brand, thickness, and adhesion. Asphalt and fiberglass felt underlayment can cost half as much in some cases but also last about half as long.
