Even with adequate roofing underlayment, water can find its way into the underlying structure of your home.
A damaged foundation could easily result in a $50,000 repair bill. You’ve already spent a fortune remodeling your bathroom, kitchen, and cellar. After saying “no” this often to your spouse, you cannot accept putting extra money into the renovations without a fight.
For this reason, you’ve decided a roof replacement is the easiest (and cheapest) way to go. But how much is this going to cost? Keep reading to discover the hidden factors that could increase the final bill.
Understanding Roof Underlayment
Before we explore the different types of roof underlayment, let’s first understand what it is and why it is essential.
Roof underlayment, also known as roofing felt or tar paper, is a protective layer installed beneath the roofing shingles. It acts as an additional barrier between the roof deck and the shingles, providing an extra defense against water intrusion. Essentially, roof underlayment is a safeguard that helps keep your roof watertight, even in the harshest weather conditions.
One of the primary functions of roof underlayment is to prevent water from seeping through the roof decking and reaching the interior of your home. Water can be a destructive force, causing rot, mold, and damage to the structural components of your roof. Roof underlayment provides an added layer of protection, ensuring that rainwater or snowmelt is channeled away from vulnerable areas and safely into the gutters and downspouts.
3 Types of Roof Underlayment
1. Asphalt-saturated Felt
Asphalt-saturated felt is the most traditional and widely used type of roof underlayment. It is made from cellulose fibers and asphalt, providing excellent waterproofing capabilities. This type of underlayment is relatively inexpensive, making it a popular choice among homeowners.
Asphalt-saturated felt comes in rolls and is applied in overlapping layers onto the roof deck. It offers good resistance against water infiltration and acts as a protective barrier against wind-driven rain. However, it is essential to note that asphalt-saturated felt has a limited lifespan compared to synthetic underlayments. It may need to be replaced when undergoing a subsequent roof replacement project.
2. Synthetic Underlayment
Synthetic underlayment is a modern alternative to asphalt-saturated felt. It is made from synthetic materials such as polypropylene or fiberglass. Synthetic underlayment offers superior durability, resistance to tears, and enhanced UV protection. While it may have a higher upfront cost than asphalt-saturated felt, its long lifespan and added benefits make it an attractive option.
One of the critical advantages of synthetic underlayment is its lightweight nature, which makes installation easier and faster. It also provides better traction for roofers during installation, enhancing safety. Synthetic underlayment is resistant to rot and decay, making it a more environmentally friendly choice than asphalt-saturated felt.
3. Rubberized Asphalt Membrane
A rubberized asphalt membrane is a premium form of roof underlayment. It is made from a combination of asphalt and rubber polymers, offering exceptional water resistance and durability. This type of underlayment is particularly recommended for areas with high humidity or extreme weather conditions.
Rubberized asphalt membrane provides superior protection against water infiltration, making it an excellent choice for areas prone to heavy rainfall or prolonged moisture exposure.
The Dangers of Not Using Roof Underlayment
Now that we have explored the importance and different types of roof underlayment let’s examine the dangers of not using it during a roof replacement.
Vulnerability to Water Damage 💧
Without adequate underlayment, your roof is highly susceptible to water damage. During heavy rain or snow, water can penetrate through the roof decking and compromise the structural integrity of your home. This can lead to costly repairs, mold growth, and compromised indoor air quality.
Water damage can have far-reaching effects, affecting not only your roof but also your ceilings, walls, insulation, and even your home’s foundation. A lack of proper underlayment leaves your home vulnerable to leaks and water infiltration, which can cause significant damage and decrease the lifespan of your roof.
Increased Risk of Roof Leaks ☔
When underlayment is absent or improperly installed, roof leaks are common. The shingles alone are insufficient to protect your roof from all weather conditions. Without a proper underlayment barrier, water can seep underneath the shingles, working its way into the roof structure and leaking into the interior of your home.
Roof leaks can result in extensive damage, including stained ceilings, damaged walls, warped flooring, and even electrical hazards. Additionally, frequent leaks can weaken the overall structure of your roof and pose a safety hazard. By neglecting to install underlayment, you are putting your home at a higher risk of experiencing roof leaks and the subsequent damage they cause.
Reduced Lifespan of Roofing Materials 💀
Without underlayment, the lifespan of your roofing materials is significantly shortened. Underlayment protects against moisture, temperature fluctuations, and other external factors that can cause roof damage.
Extreme weather conditions, such as high winds, hail, and prolonged exposure to UV rays, can degrade the shingles over time. The shingles are more prone to premature aging and deterioration without the added protection of underlayment. This can lead to the need for more frequent roof replacements or repairs, which can be expensive and disrupt your daily life.
Finding a Qualified Roofing Contractor
Finding a qualified roofing contractor is crucial when replacing your roof and ensuring the proper underlayment installation. Here are some tips to help you make an informed decision:
- Research and Compare – Take the time to research and compare different roofing contractors in your area. Look for contractors with positive reviews, years of experience, and proper licensing and insurance. Checking online reviews and testimonials can give you insights into their reputation and the quality of their work.
- Ask for References – Ask the roofing contractor for references from previous customers. Reach out to these references and inquire about their experience with the contractor, the quality of their work, and if they had underlayment adequately installed. A reputable contractor should be able to provide you with satisfied customers who can vouch for their craftsmanship.
Don’t Overlook Roof Underlayment
Understanding the importance of roof underlayment and its role in a roof replacement project is crucial for ensuring a durable and long-lasting roof. Be sure to consult a reputable roofing company and make an informed decision when selecting the proper underlayment for your specific needs. Don’t overlook this step; invest in quality underlayment and have peace of mind for years.
