Pre-Installation Checklist
Before you start installing new shingles, prepare your home and surroundings. This pre-installation checklist ensures a smooth and safe roofing project.
Mow the Yard
Start by mowing your yard. A clean yard helps you spot any roofing debris that falls during the installation. This step not only keeps your yard tidy but also ensures safety.
Move Furniture and Outdoor Items
Move any patio furniture, grills, and other outdoor items away from the house. This protects your belongings from potential damage and makes it easier to clean up after the project.
Take Pictures of the Driveway
Take clear pictures of your driveway before any roofing materials or dumpsters are delivered. This documentation is useful if there are any disputes about damage after the project.
Review Landscaping
Walk around your house and review your landscaping. Flag any concerns like landscape lighting or delicate plants. Consider covering or removing fixtures that are not hardwired to prevent damage.
Locate Power Sources
Identify any exterior power sources you might need for cutting decking or ridge vents. This ensures you have easy access to electricity throughout the project.
Staging Area
Decide on a staging area where materials should be delivered. Common spots include the driveway, side of the house, or garage. Make sure it’s easily accessible for the delivery truck.
Park Cars on the Street
Park your cars on the street while the roofing job is in progress. This keeps your vehicles safe from falling debris and allows for easier access to your garage.
Garage Access
Ensure you have access to anything you might need in the garage, such as bikes, tools, or children’s toys. Plan ahead so you won’t need to move items in and out during the project.
Ventilation
Proper ventilation is crucial. Make sure your attic and roof have adequate ventilation to prevent hot air from getting trapped, which can lead to damage over time.
Measure Ridge Caps
Measure the length of the ridges and hips on your roof. Divide this length by 35 to determine how many bundles of regular or hip-and-ridge shingles you’ll need. This ensures you purchase the right amount of materials.
By following this pre-installation checklist, you can set the stage for a successful and efficient roofing project. Proper preparation not only makes the installation process smoother but also helps in achieving a professional finish.
Next, let’s dig into the details of measuring your roof accurately to ensure you have the right amount of materials.
Measuring the Roof
Accurate measurements are crucial for a successful roof shingle installation. Here’s a simple guide to help you measure your roof correctly and ensure you have the right amount of materials.
Width and Length
Start by measuring the width and length of each section of your roof. Use a measuring tape for precise measurements. Write down the dimensions for each section.
Area Calculation
Once you have the width and length, multiply these numbers together to determine the area of each section. For example, if a section is 10 feet wide and 20 feet long, the area is:
10 feet x 20 feet = 200 square feet
Total Area
Add the areas of all sections together to get the total area of your roof. This is important for calculating the number of shingles you’ll need.
Number of Squares
Roofing materials are often sold by the “square,” which is 100 square feet. To find out how many squares your roof requires, divide the total area by 100. For example, if your total area is 2,000 square feet:
2,000 square feet ÷ 100 = 20 squares
Bundles Needed
Shingles are typically sold in bundles, with three bundles covering one square (100 square feet). To determine how many bundles you need, multiply the number of squares by 3. Using our previous example:
20 squares x 3 bundles per square = 60 bundles
Overage and Waste
It’s wise to add an additional 10 to 20 percent to account for overage and waste. This covers any mistakes, cuts, or odd-shaped sections of the roof. For instance, if you calculated 60 bundles, adding 15 percent for waste would be:
60 bundles x 1.15 = 69 bundles
By following these steps, you can ensure you purchase the right amount of materials for your roofing project. Accurate measurements not only save money but also prevent delays during installation.
Next, let’s move on to the essential safety precautions you need to take before starting your roofing project.
Safety Precautions
Before diving into the process of how to install new shingles on a roof, it’s crucial to prioritize safety. Roofing can be dangerous, so taking the right precautions can prevent accidents and injuries.
Safety Gear
Wearing the right safety gear is non-negotiable when working on a roof:
- Harness: Use a fall protection harness secured to an anchor point. Falls from roofs can be fatal.
- Hard Hat: Protect your head from falling debris.
- Work Gloves: These protect your hands from sharp edges and rough materials.
- Safety Glasses: Shield your eyes from dust, debris, and harmful UV rays.
- Long Pants: Protect your legs from scrapes and cuts.
- Tool Belt: Keep your tools handy and reduce the risk of dropping them.
Partner/Helper
Always have a partner or several helpers. They can assist with lifting materials, holding ladders, and providing an extra set of eyes for safety. Teamwork not only makes the job easier but also safer.
Manufacturer’s Instructions
Each type of shingle and roofing material comes with specific manufacturer’s instructions. Always follow these guidelines to ensure proper installation and to maintain the warranty. Missteps can lead to leaks or other issues down the line.
Additional Tips
- Check Weather Conditions: Aim to work on dry, mild days. Avoid very hot or cold days as extreme temperatures can affect materials and make the work more difficult.
- Secure Ladder: Ensure your ladder is stable and placed on a flat surface. Have someone hold the ladder while you climb.
- Clear the Area: Keep your work area clean and free of debris to prevent tripping hazards.
By following these safety precautions, you can minimize risks and focus on getting the job done right.
Next, let’s discuss the steps involved in preparing the roof for shingle installation.
Preparing the Roof
Before installing new shingles, properly prepare your roof. This involves removing old shingles, cleaning the roof deck, and ensuring everything is ready for the new materials.
Removing Shingles
Start by laying tarps on the ground to catch debris. This makes cleanup easier and protects your lawn and landscaping.
Use a roofing fork or shovel to remove the old shingles. Begin at the peak of the roof and work your way down. Insert the fork or shovel under the shingles and pry them up. Be cautious to avoid damaging the roof deck.
Tip: If you encounter stubborn nails, use a hammer to help pry them up.
Removing Nails
After lifting the shingles, you’ll need to remove the nails. Use a hammer to pull out any remaining nails. This step ensures that the new shingles will lay flat and secure.
Metal Flashing
If your roof has metal flashing, such as around chimneys or valleys, you might need to remove it. Carefully pry it up with a hammer or a pry bar. If the flashing is in good condition, you can reuse it. Otherwise, plan to install new flashing later.
Sweeping the Roof Deck
Once you’ve removed the shingles and nails, sweep the roof deck clean. This step removes any leftover nails, debris, or dirt that could interfere with the installation of new shingles.
Tarps for Debris
Throughout the process, keep tarps on the ground to catch debris. This helps keep your yard clean and makes disposal easier. After removing the old shingles and nails, gather the tarps and dispose of the debris properly.
By thoroughly preparing your roof, you set a solid foundation for the next steps in how to install new shingles on a roof. Proper preparation ensures that your new shingles will be secure and long-lasting.
Next, let’s move on to installing deck protection and starter shingles.
Installing Deck Protection & Starter Shingles
Once your roof is prepped, the next step in how to install new shingles on a roof is to install deck protection and starter shingles. This stage is crucial for ensuring your roof is weatherproof and durable.
Deck Protection
Deck protection is the first layer of defense against the elements. It acts as a barrier between your roof deck and the shingles.
- Shingle Underlayment: Start by laying down the shingle underlayment. This is typically made of felt or synthetic material. It helps prevent water from seeping into the roof deck.
- Chalk Lines: Use chalk lines to mark where each row of underlayment will go. This ensures straight, even rows.
- Cap Nails: Secure the underlayment with cap nails. These nails have a large head that helps hold the material in place.
- Overlap Rows: Overlap each row of underlayment by at least 3 to 4 inches. This overlapping helps prevent water from getting between the layers.
- Leak Barrier Protector: For areas with harsh weather conditions, consider using a leak barrier protector. This is especially important along the eaves and valleys where water tends to accumulate.
Installing New Flashing
Flashing is essential for directing water away from critical areas like chimneys, vents, and valleys.
- Drip Edge: Install a drip edge along the eaves of the roof. This metal flashing directs water into the gutters and away from the fascia.
- Hammer and Roofing Nails: Use a hammer and roofing nails to secure the drip edge. Space the nails about every 2 feet.
- Flashing Around Features: Install flashing around any roof features like chimneys or vents. This helps prevent leaks in these vulnerable areas.
Starter Shingles
Starter shingles provide a solid base for the rest of the shingles and help prevent water from getting under the edges.
- Cutting Starter Shingles: Cut off the tabs from a few shingles to create starter shingles. These will be laid along the edge of the roof.
- Align and Nail: Align the starter shingles so they overhang the drip edge by about 1/4 inch. Nail them in place using roofing nails. Ensure the nails are placed above the adhesive strip on the shingles.
- Overlap: Lay the next row of shingles so they overlap the starter shingles. This overlapping creates a watertight seal.
By following these steps, you ensure that your roof is well-protected from the elements, setting a strong foundation for the rest of the shingle installation process.
Next, we’ll dive into the detailed steps of how to install new shingles on a roof.
How to Install New Shingles on a Roof
Work Up and Across
Start laying shingles from the bottom edge of the roof and work your way up and across. This ensures that each row overlaps the one below, helping to shed water effectively.
- Align the First Shingle: Place the first shingle flush against the starter strip, ensuring it overhangs the drip edge by about 1/4 inch.
- Nail the Shingle: Hammer a nail about 2 inches from each end of the shingle. Place another nail an inch above each cutout.
Nailing Technique
Proper nailing is crucial for the durability of your roof.
- Nail Placement: Each shingle should be secured with four nails—six nails in windy areas. Ensure nails are placed in the “nail zone” specified by the manufacturer.
- Drive Nails Straight: Nails should be driven straight, not at an angle, to avoid tearing the shingles.
Shingle Alignment
Aligning shingles correctly is key to a professional-looking roof.
- Line Up Each Shingle: Place each shingle so it aligns with the previous one. Use chalk lines as a guide to keep rows straight.
- Overlap: Each row should overlap the nails of the row beneath it by at least 1 inch vertically.
Cut Shingles to Size
When you reach the end of a row, you’ll likely need to cut the last shingle to fit.
- Measure and Cut: Measure the gap and use a utility knife to cut the shingle to size.
- Fit and Nail: Fit the cut shingle into place and nail it down as usual.
Ridge Shingles
Ridge shingles cover the peak of the roof and help prevent leaks.
- Bend Shingles Over the Ridge: Bend each shingle over the ridge so that both sides are equal.
- Nail Placement: Nail each ridge shingle with a single nail on each side. Ensure the nails are covered by the next shingle.
Wind Resistance
For areas prone to high winds, you’ll need extra nails.
- Use Six Nails: Secure each shingle with six nails instead of four.
- Adhesive: Apply roofing adhesive to the heads of exposed nails for extra hold.
By following these steps, you can master the process of how to install new shingles on a roof, ensuring a durable and weather-resistant finish. Next, let’s look at the specifics of installing ridge shingles.
Installing Ridge Shingles
Ridge shingles are crucial for sealing the peak of your roof and preventing leaks. Here’s how to install them properly:
Bend Shingles Over the Ridge
- Prepare the Shingles: Ridge shingles are usually pre-cut or can be made by cutting regular shingles into sections. Bend each shingle over the ridge so that both sides are equal.
- Align Properly: Ensure the shingle sits flat and covers the ridge evenly. This helps to create a uniform look and provides better protection.
Nail Placement
- Secure Each Shingle: Nail each ridge shingle with a single nail on each side, about an inch from the edge.
- Cover the Nails: Make sure the nails are covered by the next shingle in the row. This prevents water from seeping through the nail holes.
Use Asphalt Cement
- Apply Cement: For added security, apply a dab of asphalt cement under each ridge shingle. This helps to hold the shingle in place and seals any gaps.
- Press Down: Press the shingle firmly into the cement to ensure a tight seal.
Cover Nails
- Seal Exposed Nails: Once you reach the end of the ridge, cover any exposed nail heads with asphalt cement. This prevents water from leaking through the nail holes.
- Smooth the Cement: Use a putty knife to smooth out the cement, ensuring a clean finish.
Prevent Leaks
- Overlap Properly: Each ridge shingle should overlap the previous one by at least 5 inches. This creates a continuous barrier against water.
- Check for Gaps: Inspect the ridge for any gaps or misaligned shingles. Fix them immediately to prevent leaks.
By following these steps, you’ll ensure that your ridge shingles are installed correctly, providing a durable and leak-proof finish. Next, let’s address some frequently asked questions about installing new shingles.
