What is the best underlayment for roofing on your home? If you’re scheduling extensive repairs or new roof installation, it’s vital to consider this question. A roofer might suggest various materials given your budget and roof design. However, it’s often up to the homeowner to make the final decision.
The best underlayment for roofing includes:
To make the best decision for your home’s new roof, keep reading! Some added information about each choice ensures you’re happy with your roof for years to come. You’ll also know what to discuss with your roofing contractor when they offer their suggestions for underlayment material.
Knowing more about roofing underlayment, including its purpose and roofing installation, is helpful when it’s time to choose a material. First, note that a contractor builds a roof in layers, starting with decking. Thick plywood sheets make up this decking, attached to a home’s framing. Next, your contractor applies underlayment to that decking.
This underlayment provides added waterproofing, weather insulation, and sound insulation. Also, underlayment encourages water to run off the roof rather than puddles between shingles or tiles. This helps prevent ice dams and premature water damage. Shingles or tiles then attach over that underlayment.
There is no “best” underlayment material for roofing, as they each offer pros and cons. They also have varying price points, so of course you’ll need to consider your budget when deciding.
Also called felt paper, felt underlayment has been a popular choice with roofers for decades. Polyester and natural plant fibers soaked in bitumen or asphalt make up this material. It’s generally the most affordable of all your options.
However, due to its weight, manufacturers make felt underlayment in shorter rolls than other materials. In turn, it often takes roofers longer to install felt paper. Also, it’s prone to tearing. In turn, your contractors need to install shingles or tiles quickly, to protect felt against damage.
Peel-and-stick rubberized roofing underlayment applies quickly and easily. The rubber material provides a naturally watertight seal, encouraging water runoff. This prevents ice dams along roof eaves and premature cracks and leaks.
However, some roofers might suggest using rubberized underlayment with another material as rubber isn’t the best insulator. Synthetic or felt helps provide added temperature and sound insulation. Using more than one material provides maximum protection for the roof and interior spaces.
Synthetic is a popular choice for roof underlayment as it’s lightweight and waterproof. Also, some manufacturers print shingle installation outlines right on the underlayment facing. This makes a roofing project faster and easier on a contractor!
While synthetic isn’t always the cheapest option, its lighter weight allows manufacturers to produce it in larger rolls. In turn, installation is often faster than with felt or rubber underlayment materials. Additionally, contractors don’t need to work as quickly to cover synthetic underlayment as they do felt.
After considering your budget, it’s good to choose a roof underlayment based on the roofing material, climate, and installation.
Rubber roofing underlayment is excellent for colder climates, as it prevents ice dams. What are these and how do they affect a roof? First, consider that roofs are often warmer near the center and cool around their edges. Second, during winter months, melting snow starts to roll off the roof where it should then end up in gutters.
However, those cool edges can allow water to freeze before it leaves the roof. This ice then creates a “dam,” and blocks water from rolling off the roof. That water sitting on the roof damages shingles or tiles and increases the risk of cracks and resultant leaks.
In turn, a contractor might recommend rubber roof underlayment for colder climates and especially those prone to heavy snowfall. Also, they might recommend a rubber drip edge. This refers to installing rubber underlayment just around the roof’s outer areas. A rubber underlayment around the edges helps prevent those ice dams and protects a roof overall.
Since felt paper is so heavy, manufacturers supply it in shorter rolls, as said. In turn, you can expect more trips up and down the ladder for felt underlayment installation! Roofing contractors often charge more for this added time and effort.
Synthetic underlayment is lighter, so manufacturers usually supply it in longer rolls. However, synthetic underlayment requires special nails for installation, which are usually more expensive. They also require more effort for installation.
Rubber underlayment offers an easier installation process. Many brands offer a peel-and-stick backing, so roofers don’t even need nails or staples. In turn, contractors might charge less for rubber than other materials.
In conclusion, there is no “right or wrong” answer as to the right underlayment material for your home. Consider your budget, climate, and roofing materials when deciding. Your roofing contractor can also offer excellent advice for your property as well.
