What is Asphalt Roofing Paper? Understanding the Basics

Alright, guys, before we get to the juicy stuff, let's nail down what asphalt roofing paper actually is. Think of it as a protective layer, a barrier between your roof's decking (usually plywood or OSB) and the shingles or other roofing materials you choose. Also known as underlayment, this paper is typically made from a combination of cellulose fibers (like wood pulp) or fiberglass, saturated with asphalt. The asphalt acts as a waterproofing agent, ensuring that any moisture that finds its way under your shingles doesn't wreak havoc on your roof's structure. It's like the unsung hero of your roof, working tirelessly to keep your home safe and sound.

There are different types of asphalt roofing paper, each offering varying levels of protection and durability. Some are designed for standard shingle applications, while others are more robust and better suited for climates with heavy rainfall or snow. Understanding these distinctions is key to making the right choice for your specific needs.

Historically, felt paper was the go-to underlayment. It's relatively inexpensive and provides decent protection. However, modern advancements have introduced synthetic underlayments, which are often preferred for their superior water resistance, durability, and tear strength. Synthetic underlayments are usually made from polypropylene or polyester, making them more resistant to mold, mildew, and UV damage. When you're browsing the aisles at Home Depot, you'll likely encounter both types, so it's a good idea to familiarize yourself with the pros and cons of each to make an informed decision. Remember, the right underlayment is an investment in the long-term health and lifespan of your roof. Choosing the wrong one can lead to premature failure and costly repairs down the road, so take your time and do your research! Don't worry, we'll cover how to choose the right one in more detail later on.

Asphalt Roofing Paper Types and Their Applications

Okay, let's break down the different types of asphalt roofing paper you're likely to encounter at Home Depot. Knowing the differences will help you pick the perfect one for your project. The main types include felt paper and synthetic underlayment.

Felt Paper

Felt paper, as we mentioned earlier, is the traditional choice. It's usually graded by weight, with 15-pound and 30-pound felt being the most common. 15-pound felt is suitable for most residential applications, while 30-pound felt offers a bit more durability and is often recommended in areas with harsher weather conditions.

Pros:

Cost-effective: Generally, felt paper is cheaper than synthetic alternatives, which can be a significant factor if you're on a tight budget.
Familiar: Roofers have been using felt paper for ages, so it's a well-understood material with readily available installation guidelines.

Cons:

Less Durable: It's more susceptible to tearing, especially in windy conditions or during installation.
Water Absorption: Felt paper can absorb moisture, which can lead to it swelling and wrinkling, potentially compromising the integrity of your roof over time.
Shorter Lifespan: Compared to synthetic underlayments, felt paper tends to have a shorter lifespan.

Synthetic Underlayment

Synthetic underlayment is the modern marvel of roofing underlayments. It's made from materials like polypropylene or polyester, which are designed to be waterproof, durable, and resistant to the elements.

Pros:

Superior Water Resistance: Synthetic underlayment is virtually impervious to water, providing excellent protection against leaks.
Durability: It's much stronger than felt paper and resists tearing, even under challenging conditions.
Longer Lifespan: Synthetic underlayments are built to last, often outlasting the shingles themselves.
UV Resistance: Many synthetic underlayments are treated to resist UV damage, extending their lifespan.
Slip-Resistant Surface: Provides a safer working surface for roofers, especially when the roof is wet.

Cons:

Higher Cost: Synthetic underlayment typically costs more than felt paper.

When choosing between felt and synthetic underlayment, consider your budget, the climate you live in, and the expected lifespan of your roof. For most homeowners, the added protection and durability of synthetic underlayment make it the superior choice, despite the higher upfront cost. It's a wise investment in the long run.

Installing Asphalt Roofing Paper: A Step-by-Step Guide

Alright, you've selected your asphalt roofing paper and are ready to install it. Here's a basic guide to get you started. However, always consult the manufacturer's instructions for the specific underlayment you've chosen, as installation methods may vary. Additionally, if you're not comfortable with this type of work, consider hiring a professional. Roof work can be dangerous, so safety first, folks! This is a simplified explanation.

Preparation is Key

Safety First: Wear appropriate safety gear, including a safety harness, gloves, eye protection, and non-slip work boots.
Clean the Deck: Ensure the roof deck is clean, dry, and free of any debris, such as old nails, leaves, or loose pieces of wood.
Inspect the Decking: Check for any damaged or rotted wood and make necessary repairs before installing the underlayment.

Installation Steps

Start at the Eaves: Begin at the bottom edge (eaves) of the roof. This ensures that the underlayment overlaps properly, directing water flow downward.
Roll it Out: Unroll the asphalt roofing paper horizontally, ensuring that it lies flat on the roof deck.
Overlap: Overlap each course (horizontal row) by the amount specified by the manufacturer (usually a few inches). This creates a watertight seal.
Secure with Fasteners: Use the recommended fasteners (staples or nails) to secure the underlayment to the roof deck. Follow the manufacturer's instructions for spacing and placement. Do not over-fasten, as this can damage the underlayment.
Seal the Seams: Use seam tape to seal the horizontal seams, especially if you’re using a synthetic underlayment.
Work Around Obstructions: Cut the underlayment carefully around chimneys, vents, and other roof penetrations.
Overhang: Extend the underlayment slightly beyond the roof edge (the overhang) to protect the fascia and gutters.
Complete the Roof: Once the underlayment is installed, install the shingles or other roofing materials according to their manufacturer's instructions.

Important Tips

Work in Dry Weather: Avoid installing asphalt roofing paper in wet or windy conditions.
Follow the Manufacturer's Instructions: Always consult the manufacturer's specific instructions for your chosen underlayment.
Use Proper Tools: Use the correct tools for the job, such as a utility knife, measuring tape, and a staple gun or nail gun.
Consider Temperature: Some underlayments can become difficult to work with in extreme temperatures. Check the manufacturer's recommendations.

Home Depot is a great place to start, as they have all the tools and accessories needed for asphalt roofing paper installation. If you are not familiar with the installation steps, please hire a roofing professional.

Asphalt Roofing Paper Maintenance and Troubleshooting

Great job on getting your asphalt roofing paper installed! Let's talk about maintenance and some common troubleshooting tips to keep your roof in tip-top shape. Regular inspection and addressing any issues promptly can extend the life of your roof and prevent costly repairs down the road.

Inspection and Maintenance

Regular Inspections: Inspect your roof at least twice a year (spring and fall) and after any severe weather events. Look for signs of damage or wear, such as tears, wrinkles, or blistering in the underlayment. Also, inspect your shingles, looking for damage or missing parts.
Cleaning: Keep your roof clear of debris, such as leaves, branches, and moss. This helps prevent water from accumulating and potentially damaging your roof. Clear out your gutters regularly as well, to allow water to run off properly.
Trimming Overhanging Branches: Trim any tree branches that overhang your roof. This reduces the risk of branches falling and damaging your roof. It also reduces the amount of debris falling onto your roof.

Troubleshooting Common Issues

Tears or Punctures: If you find any tears or punctures in the underlayment, patch them immediately with a piece of compatible underlayment and seam tape. If the damage is extensive, you may need to replace the damaged area.
Wrinkling or Buckling: Some wrinkling can be normal, especially with felt paper. However, excessive wrinkling can indicate a problem. Check the fasteners and make sure the underlayment is properly secured. If the wrinkling is severe, you may need to replace the underlayment. Synthetic underlayment resists wrinkling, making it the better choice.
Water Leaks: If you notice water leaks, check for any damage to the shingles, flashing, or underlayment. Repair any damage immediately. If the underlayment is damaged, you will have to remove the shingles in that area.
Blistering: Blistering can occur, especially with felt paper. It is typically caused by trapped moisture. If blistering is severe, it can compromise the underlayment's effectiveness. Consider replacing the underlayment if blistering is extensive. Synthetic underlayment is less prone to this.

When to Seek Professional Help

While you can handle some minor repairs, it's always best to call a professional for complex issues or if you're not comfortable working on your roof. Roofing professionals have the expertise and equipment to diagnose and repair any roofing problems safely and effectively. If you're unsure about anything, don't hesitate to seek professional help. Your roof is a crucial part of your home and protecting it is very important.
