Asphalt Shingle Roofing: Sealing for Longevity
Introduction: The Value of Asphalt Shingle Roofing
Asphalt shingle roofing is a popular choice among homeowners due to its affordability, ease of installation, and versatility in styles. However, to ensure your roof’s optimal performance and longevity, proper sealing techniques are essential. This guide delves into the art of sealing asphalt shingles, offering valuable insights on cost, installation, repair, and choosing the best brands for a long-lasting roof.
Understanding Asphalt Shingle Roofs: Basics and Benefits
What Are Asphalt Shingles?
Asphalt shingles are composite materials made from asphalt bound together with fibers, such as glass or cellulose. They offer a cost-effective alternative to traditional roofing materials like slate or tile, while still providing excellent protection against the elements.
Advantages of Asphalt Shingle Roofing:
- Affordability: One of the most significant advantages is its competitive pricing compared to other roofing options.
- Ease of Installation: Asphalt shingles are lightweight and easy to install, making them a popular choice for both new constructions and renovations.
- Versatility: They come in various colors, styles, and textures, allowing homeowners to choose a look that complements their home’s architecture.
- Durability: With proper maintenance, asphalt roofs can withstand extreme weather conditions, offering long-term protection for your home.
Why Seal Asphalt Shingles?
Sealing asphalt shingles is crucial for several reasons:
- Protection Against Elements: Sealing creates a protective barrier against water, UV rays, and other environmental factors that can degrade the shingles over time.
- Extended Lifespan: By sealing your roof, you significantly increase its lifespan, reducing the need for frequent replacements.
- Improved Energy Efficiency: A sealed roof helps maintain a consistent indoor temperature, leading to energy savings on heating and cooling costs.
- Preventive Maintenance: Regular sealing is an easy and affordable way to stay ahead of potential issues like leaks or deteriorated shingles.
The Asphalt Shingle Sealing Process
Step 1: Inspect and Prepare the Roof
Before sealing, thoroughly inspect your roof for any damage, loose shingles, or flashing issues. Repair or replace damaged shingles to ensure a solid foundation for the sealing process. Clean the roof surface, removing debris, dirt, or algae buildup that could interfere with the sealant’s adhesion.
Step 2: Choose the Right Sealing Product
Select a high-quality asphalt shingle sealant designed specifically for your climate and roof type. There are two primary types:
- Bitumen-based Sealants: These are traditional, cost-effective options that provide good protection against water penetration. They are suitable for most climates and easily applicable with a brush or sprayer.
- Acrylic-modified Sealants: Offering enhanced flexibility and resistance to UV rays, these sealants are ideal for warmer, sunnier regions. They provide superior durability and reflectivity, helping to keep your roof cooler.
Step 3: Apply the Sealer
Carefully follow the manufacturer’s instructions when applying the sealant. Typically, this involves:
- Brushing or Spraying: Evenly apply the sealant over the entire roof surface, ensuring complete coverage. For hard-to-reach areas, a brush is more suitable, while a sprayer can be used for larger surfaces.
- Not Overloading: Avoid applying too much sealant, as it may run and waste valuable material. A thin, even layer is all that’s needed.
- Allowing Drying Time: After application, give the sealant sufficient time to dry according to the manufacturer’s guidelines. This ensures optimal bonding with the shingles.
Asphalt Shingle Roofing Cost: Budgeting for Sealing
The cost of sealing asphalt shingles depends on several factors:
- Roof Size: Larger roofs will require more materials and labor, making them more expensive to seal.
- Sealer Type: Premium acrylic-modified sealants are generally more expensive than traditional bitumen-based options.
- Contractor’s Fees: Hiring a professional contractor for sealing services incurs additional costs but ensures expert application and warranty coverage.
On average, expect to spend between $1 and $3 per square foot for sealant materials, with labor costs varying based on the complexity of your roof and the contractor’s rates. For a typical 1500 square foot roof, sealing could range from $1500 to $4500, including materials and labor.
Install Asphalt Shingles: A Step-by-Step Guide
Sealing goes hand in hand with proper installation for optimal shingle performance. Here’s a simplified guide:
- Measure and Cut Shingles: Determine the exact amount of shingles needed based on your roof’s square footage. Cut the shingles to size using a utility knife or circular saw, ensuring precise measurements for a neat finish.
- Prepare Underlayment: Install a layer of roofing underlayment (felt paper) over the roof deck to provide extra protection against moisture and pests. Secure it with staples or nails according to manufacturer instructions.
- Start at the Ridge: Begin installing shingles at the ridge, working down to the eaves. Fasten them tightly with nails, ensuring proper overlap as you go.
- Cut and Install Valleys: For areas like valleys (where two roof planes meet), cut and install shingles to create a water-tight seal, preventing water from pooling and causing damage.
- Finish at Eaves: Complete the installation by securing the shingles at the eaves, ensuring they are properly sealed and fastened.
Repairing Damaged Asphalt Shingles
Regular inspections are key to maintaining your asphalt roof. If you notice damaged or missing shingles, prompt action is essential:
- Small Cracks or Chips: Use a roofing cement or repair kit to fill small cracks or chips in the shingle surface. Allow it to dry completely before sealing.
- Missing Shingles: Replace missing shingles as soon as possible to prevent water penetration. Ensure proper alignment and fastening for a secure fit.
- Major Damage: For extensive damage, consider consulting a professional roofer. Major repairs might require new underlayment or even a partial roof replacement.

Long-Lasting Asphalt Shingles: Tips for Homeowners
To ensure your asphalt shingles provide long-term protection, consider these additional tips:
- Regular Maintenance: In addition to sealing, schedule periodic inspections and cleaning to keep your roof in top condition. Remove debris buildup, especially after storms, to prevent water damage.
- Avoid Walking on the Roof: Excessive foot traffic can damage shingles, leading to leaks or premature deterioration. Limit access to the roof and avoid walking on it unless absolutely necessary.
