Understanding the Basics of Asphalt Shingle Roof Installation
Installing an asphalt shingle roof may seem complicated, but understanding the basics can make the process much clearer. Let’s break down the key concepts: gravity, water shedding, overlapping, and roof components.
Gravity and Water Shedding
The main job of an asphalt shingle roof is to shed water. Gravity helps with this by pulling water down the slope of the roof. When it rains, water flows from the top of the roof down to the eaves, where it drips off.
Key Point: Shingles must be installed in a way that allows water to flow downward naturally. Any obstruction can cause water to pool and potentially damage your roof.
Overlapping
The term “to shingle” means “to lay out or arrange so as to overlap.” This is crucial for water shedding. Each shingle overlaps the one below it, creating a barrier that prevents water from seeping through.
Pro Tip: Start from the bottom and work your way up. Each row of shingles covers the nails of the row below, protecting them from exposure to the elements.
Roof Components
A well-installed asphalt shingle roof involves more than just shingles. Here are the main components:
- Roof Deck: The base layer, usually made of plywood or oriented strand board (OSB). It must be smooth and properly fastened.
- Underlayment: A protective layer that goes over the roof deck. Types include asphalt felt paper or self-healing membranes.
- Drip Edge: Metal flashing installed at the roof’s edges to direct water away.
- Ice and Water Protector: A special underlayment for areas prone to ice dams or heavy rain.
- Flashing: Metal pieces used to prevent water from entering through joints and valleys.
- Starter Shingles: The first row of shingles installed at the eaves, ensuring proper alignment for the rest of the shingles.
- Ridge Caps: Shingles specifically designed to cover the roof’s peak, providing a finished look and extra protection.
Reminder: Each component plays a vital role in the overall performance of your roof. Skipping any of these steps can lead to problems down the road.
Visualizing the Layers
To help you visualize, here’s a simple diagram:

Understanding these basics sets you up for a successful asphalt shingle roof installation. Now, let’s move on to the next step: preparing the roof deck.
Preparing the Roof Deck
Before you start installing shingles, you need to prepare the roof deck properly. This step is crucial to ensure a smooth and long-lasting asphalt shingle roof installation.
Smooth Surface
First, make sure the roof deck is smooth. Any bumps or rough spots can cause problems later on. If your roof deck is made of plywood or OSB, check for any loose or damaged areas. Replace any faulty sections to create an even surface.
Fastened Deck
Next, ensure the roof deck is securely fastened. Loose boards can shift and cause leaks. Use nails or screws to fasten any loose areas. This will provide a stable base for your shingles.
Clean Deck
A clean deck is essential. Remove any old nails, debris, or dirt. Sweep the deck thoroughly. This helps the underlayment and shingles adhere better. It also reduces the risk of damage from leftover debris.
Drip Edge
Installing a drip edge is a key step. The drip edge is a metal flashing that directs water away from the roof deck and fascia. Place it along the edges of the roof. Nail it down securely. This helps prevent water from getting under the shingles and causing rot.
Ice Dam Protection
If you live in a cold climate, ice dam protection is a must. Ice dams form when melted snow refreezes at the roof’s edge, forcing water back under the shingles. Install an ice and water protector membrane over the drip edge at the eaves. This self-adhering membrane creates a waterproof barrier.
Tip:
The ice and water protector should extend at least 24 inches inside the vertical extension of the interior wall to be fully effective.
By following these steps, you’ll have a well-prepared roof deck that sets the stage for a successful shingle installation. Next, we’ll go over installing underlayment and flashing.
Installing Underlayment and Flashing
Before you start installing shingles, you need to lay down the underlayment and flashing. These components are crucial for protecting your roof from water damage.
Underlayment Types
There are two main types of underlayment:
- Asphalt-Saturated Felt: Also known as tar paper, this traditional material is effective but can be heavy and less durable than newer options.
- Synthetic Underlayment: Made from polymers, this option is lighter, more durable, and often provides better water resistance.
Both types of underlayment offer peace-of-mind protection beneath the shingles. Choose the one that best fits your climate and budget.
Ice and Water Protector
Ice dams can cause water to back up under the shingles, leading to leaks. An ice and water protector is a self-adhering membrane that goes on over the drip edge at the eaves. It seals around the shanks of overlying shingle fasteners, providing an extra layer of water-shedding protection.
Tip: The ice and water protector should extend at least 24 inches inside the vertical extension of the interior wall to be fully effective, as recommended by David Bitan.
Drip Edge
Drip edges are installed at the edges of the roof to prevent water from damaging the roof deck. They are crucial for directing water away from the fascia and into the gutters.
- At the Eaves: Install the drip edge under the ice and water protector.
- At the Rakes: Install the drip edge on top of the underlayment. This creates a clean roof edge and provides better wind resistance.
Flashing
Flashing is used wherever the shingle layer is interrupted, such as around chimneys, vents, and valleys. It helps prevent leaks by directing water away from these vulnerable areas.
- Valleys: Valleys can either be open or closed. Open valleys are lined with a pre-formed width of corrosion-resistant metal, while closed valleys are covered with shingles. IKO recommends using open metal valleys for longer roof performance.
- Around Penetrations: Use metal flashings around plumbing stacks, attic vents, and other roof penetrations. This is critical to prevent leaks.
Tip: Use a 28-gauge galvanized metal or an equivalent corrosion-resistant, non-staining material for flashing, as suggested by IKO.
By carefully installing underlayment and flashing, you provide a strong foundation for your asphalt shingles. This step is essential for a durable and leak-free roof.
Next, we’ll dive into the step-by-step guide to asphalt shingle installation.
Step-by-Step Guide to Asphalt Shingle Installation
Starter Shingles
Starter shingles are the first layer you lay down. They provide a sealant adhesion point and protect the eaves from water damage. You can use specially manufactured starter shingles or cut a regular shingle to size.
Tip: Start at the bottom of the roof and work your way up. This ensures proper water shedding.
Nailing Technique
Proper nailing is crucial for the durability of your roof. Use 1¼ inch roofing nails and make sure they are driven flush with the shingle, but not cutting into it.
Tip: Place nails about 2 inches from each end of the shingle and 1 inch above each cutout. This not only secures the shingles but also enhances wind resistance.
Overlapping
Overlapping the shingles correctly is essential. Each shingle should overlap the one below it by about 6 inches. This ensures that water runs off the roof properly and doesn’t seep through.
Tip: Use a chalk line to mark guidelines on the underlayment. This will help you maintain straight rows and consistent overlap.
Chalk Lines
Chalk lines are your best friend for maintaining straight and even rows. Snap a chalk line about every 4 rows of shingles. This will act as a guide and make sure your shingles are aligned properly.
Tip: Mark from left to right across the roof. This will ensure that your rows are straight and evenly spaced.
Ridge Caps
Once you’ve installed the field shingles up to the peak, it’s time to install the ridge caps. These are individual shingles that cover the ridge and hips of the roof.
Tip: Start at the end of the ridge opposite the prevailing wind direction. This helps to maximize wind resistance. Use longer nails for the ridge caps to ensure they penetrate through the last course of shingles and into the roof deck.
Example: On hip roofs, you can start at each end of the ridge and meet in the middle. The last piece should be nailed in place and covered with asphalt roof cement to seal the exposed nail heads.
By following these steps, you’ll ensure a solid and leak-free asphalt shingle roof installation. Next, we’ll look at common mistakes to avoid.
Common Mistakes to Avoid
When it comes to asphalt shingle roof installation, even small mistakes can lead to big problems. Here are some common errors to watch out for:
Incorrect Nailing
Nailing is crucial. Use four nails per shingle, and six on the windward side. Incorrect nailing can lead to shingles flying off in high winds.
Example: A homeowner in Southern California ignored local codes requiring six nails on all sides. After a windy day, they found shingles scattered in their yard. Always follow local codes and use the right number of nails.
Improper Overlap
Shingles need to overlap correctly to prevent leaks. Each shingle should cover the nails of the one below it by about 1 inch vertically and 1/2 of a tab horizontally.
Tip: Use chalk lines to ensure straight rows and proper overlap. Incorrect overlapping can lead to water seeping through and causing damage.
Inadequate Ventilation
Proper ventilation is essential to prevent heat and moisture buildup in the attic. Poor ventilation can lead to shingles curling and even structural damage.
Fact: An improperly ventilated attic can cause shingles to curl up at the ends due to excessive heat. Ensure you have adequate vents and that they are not blocked.
Insufficient Underlayment
Underlayment is your roof’s first line of defense against leaks. Skimping on this layer can lead to serious water damage.
Advice: Use at least 15-pound asphalt roofing paper and make sure it’s installed correctly. In colder climates, consider an ice and water protector to guard against ice dams.
Avoid these common mistakes to ensure a durable and leak-free roof. Next, we’ll answer some frequently asked questions about asphalt shingle roof installation.
Frequently Asked Questions about Asphalt Shingle Roof Installation
How should shingles be installed on a roof?
Overlapping is key. Each shingle must overlap the one below it to ensure water sheds properly. Start at the bottom edge of the roof and work upwards. The first row should hang over the drip edge by about a half-inch to prevent water from seeping underneath.
Solid Quarter Inch: Make sure each shingle row overlaps the previous one by a solid quarter inch. This helps in maintaining a tight seal and reduces the risk of wind damage.
What is the labor cost to install a shingle roof?
The cost per square foot for labor can vary widely based on location, roof complexity, and the contractor’s experience. On average, expect to pay around $2 to $4 per square foot for labor alone. For a typical 1,800-square-foot roof, labor costs can range from $3,600 to $7,200.
Hourly Rates: Some contractors may charge by the hour, with rates usually between $50 and $100 per hour. The total cost will depend on how many hours the job takes, which can be influenced by the roof’s pitch and the number of workers involved.
