To Tear Off or To Go Over? Installing Over Shingles

When considering a metal roof, a common question arises: should you remove your old shingles (a “tear-off”) or install the metal right over them (an “overlay” or “re-cover”)? Both options have their pros and cons, and the right choice often depends on your specific situation, local building codes, and budget.

The Benefits of a Tear-Off:

Choosing to tear off your old shingles gives you a clean slate. It allows for a thorough deck inspection, meaning we can check the plywood or OSB underneath for any damage, rot, or soft spots. This is a crucial step because a solid, healthy roof deck is the foundation of a long-lasting metal roof. Any issues found can be addressed and repaired, ensuring your new metal roof has the best possible base. A tear-off also results in a flatter surface, which is ideal for metal panels, helping them lie perfectly flat and straight for a smooth, aesthetically pleasing finish. Plus, it ensures code compliance, as many local building codes limit the number of roofing layers allowed on a home.

The Benefits of an Overlay:

On the other hand, installing a metal roof directly over existing shingles, if permitted by code, can offer some attractive advantages. The most immediate benefits are often cost savings on labor and disposal fees, as there’s no need to remove and haul away old materials. It also translates to time savings, as the installation process can be quicker without the demolition phase. Environmentally, an overlay means less landfill waste, which is always a plus!

Key Considerations for Your Decision:

Before deciding, check your local building codes. Many municipalities have strict rules about how many layers of roofing are allowed. Typically, you can’t have more than two layers, so if your home already has two layers of shingles, a tear-off is your only option. We’ll also consider the number of shingle layers already present and the condition of the existing roof. If your current shingle roof is severely deteriorated or uneven, an overlay might not be suitable, as it could compromise the flatness and integrity of your new metal roof.

How to Accurately Measure Your Roof

Accurate measurements are vital for any roofing project, especially with metal, to ensure you order enough material and minimize waste. It’s a bit like baking – you need the right amount of ingredients for a perfect cake!

Measurement Steps:

First, you’ll need to calculate the roof area. For simple rectangular sections, this is straightforward: length multiplied by width. For more complex roofs with multiple sections, you’ll break it down into smaller, manageable rectangles or triangles and add up their areas.

Next, you need to determine the slope of your roof. This is often expressed as “rise over run” (e.g., 6/12 means the roof rises 6 inches for every 12 inches it runs horizontally). You can find this by measuring a horizontal distance (the “run”) and then measuring the vertical distance (the “rise”) over that same horizontal distance. This slope is crucial because metal panels are designed to shed water efficiently based on your roof’s pitch.

Finally, you’ll calculate the slope factor. This is a multiplier that accounts for the actual surface area of a sloped roof being greater than its flat footprint. There are charts available online or through roofing suppliers that provide these factors based on your roof’s rise over run. You’ll multiply your flat roof area by this factor to get the true square footage of roofing material needed.

Ordering Materials:

Once you have your accurate roof area measurement, it’s wise to add 10-15% extra for waste and cuts. Even the most experienced installers will have some off-cuts, and a little extra ensures you won’t be caught short in the middle of your project, waiting for more materials to arrive. This small buffer can save you a big headache down the line!

Planning Your Metal Roof Installation Project

Proper planning is the foundation of a successful roofing project. Before a single panel is laid, it’s crucial to understand your material options, decide on an installation approach, and accurately measure your roof. This initial phase saves time, prevents costly errors, and guarantees a result that meets your expectations.

Choosing the Right Metal Roofing Materials

Selecting the best material and style for your home’s aesthetic, budget, and the Delaware climate is a key first step.

Types of Metal Roofing Materials:

Material Lifespan Cost Corrosion Resistance
Steel 30-50 years Mid-range Good (coated)
Aluminum 30-50 years High Excellent (coastal areas)
Copper Up to 200 years Very High Excellent
Zinc 80-100 years Very High Excellent

Panel Styles:

  • Standing Seam: Our top recommendation for homes. It features raised, interlocking seams that hide fasteners, offering superior leak protection, minimal maintenance, and a sleek, modern look.
  • Exposed Fastener: A more economical option where panels are secured with visible, gasketed screws. While common for barns, it’s also a cost-effective choice for homes, though fasteners may need maintenance after 20-25 years.
  • Metal Shingles: These combine the durability of metal with the traditional appearance of asphalt, wood, or slate shingles, offering a versatile look.

To Tear Off or To Go Over? Installing Over Shingles

A key decision is whether to remove old shingles (a tear-off) or install the new metal roof over them (an overlay). A tear-off is our general recommendation. It allows for a full inspection of the roof deck, so we can repair any rot or damage, ensuring a solid foundation. It also provides a flatter surface for the new panels and ensures compliance with building codes that often limit roof layers. An overlay can save on labor and disposal costs and is quicker. However, it’s only an option if your existing roof is in good condition (typically one layer, no major damage) and local codes permit it. A tear-off ensures the best performance for critical components like the ice and water shield, which adheres best directly to the deck.

How to Accurately Measure Your Roof

Accurate measurements are vital for ordering the right amount of material and minimizing waste.

Measurement Steps:

  1. Calculate Roof Area: Measure the length and width of each roof plane and multiply to find the square footage. Sum all planes for the total area.
  2. Determine Slope: Find the roof’s pitch (e.g., 6/12), which is the vertical rise for every 12 inches of horizontal run.
  3. Apply Slope Factor: A sloped roof has more surface area than its flat footprint. Use a slope factor (found in roofing guides) to multiply your flat area and get the true material quantity needed.
  4. Order Extra: Always add 10-15% to your final calculation to account for waste from cuts, trim, and potential mistakes.

Essential Tools, Components, and Safety Precautions

A professional metal roof installation relies on using the right components and prioritizing safety. From the underlayment that provides a critical moisture barrier to the specific fasteners that hold everything together, every piece plays a role. Equally important is adhering to strict safety protocols to protect both the installers and your property.

Essential Components for a Watertight System

A successful metal roof is a system of parts working together to keep your home dry. Key components include:

  • Substrate/Decking: The plywood or OSB base of the roof, which must be solid and dry.
  • Underlayment: A waterproof barrier applied to the deck. We use high-quality synthetic underlayment, with a self-adhering Ice & Water Shield in critical areas like eaves and valleys for extra protection.
  • Metal Panels: The primary, durable weather-facing material in your chosen style.
  • Trim & Flashing: Custom-fit metal pieces for eaves, gables, valleys, and ridges that direct water away from edges and joints.
  • Fasteners: Specialized screws with rubber washers (for exposed fastener systems) or hidden clips (for standing seam) that secure panels properly.
  • Sealant & Butyl Tape: Used to create waterproof seals at joints, overlaps, and penetrations.
  • Closure Strips: Foam inserts that fit under ridge caps and at eaves to block pests, debris, and wind-driven rain.

To see how these components come together in a professional installation, learn more about our professional roof installation services.

Tools of the Trade

A skilled installation requires specialized tools. A professional’s toolkit will include:

  • Ladders and/or scaffolding
  • Tape measure and chalk line
  • Drill with a clutch and a screw gun
  • Metal snips, shears, or a metal-cutting circular saw blade
  • Hand seamer for bending trim
  • Utility knife and caulking gun

Critical Safety Measures for Roof Installation

Safety is our top priority on every job site. Working at height with metal panels requires strict adherence to safety standards.

  • Fall Protection: Our installers always use personal fall arrest systems, including safety harnesses and lifelines securely anchored to the roof.
  • Proper Gear: Non-slip boots are essential for traction, while heavy-duty gloves and safety glasses protect against sharp edges and debris.
  • Site Awareness: We constantly monitor weather conditions and never work in high winds or rain. We ensure ladders are secure and are always mindful of potential hazards like overhead power lines. We also take care when handling hot metal panels and clear the area for material staging and debris removal.

The Step-by-Step Guide to Metal Roof Installation

The actual metal roof installation process is a systematic layering of components. Each step is designed to make sure your roof sheds water and stands strong against the elements. Following these steps carefully is essential for a durable, leak-free roof that will truly last a lifetime.

Step 1: Preparing the Roof Deck

This foundational step is critical for the long-term performance of your new roof. First, we prepare the deck by removing old roofing materials (if it’s a tear-off), inspecting for and repairing any rot or damage, and sweeping the surface clean. Next, we install a high-quality synthetic underlayment, starting from the eaves and working up, ensuring each course overlaps the one below it. For extra protection in vulnerable areas like valleys and eaves, we apply a self-adhering ice and water shield.

Step 2: Installing Trim and Flashing

Trim and flashing are essential for protecting the roof’s edges and joints from water intrusion. We begin by installing the eave trim (drip edge) along the bottom edge of the roof to guide water into the gutters. If the roof has valleys, we then install pre-formed valley flashing to create a secure, waterproof channel before the main panels are laid.

Step 3: Laying the Metal Panels

Proper panel placement is key to a professional look and watertight performance.

  • Layout and First Panel: We snap a square reference line to ensure the panels are perfectly straight. The first panel is aligned with this line and the eave, with a slight overhang (¾ to 1 inch) to direct water into the gutter. Getting this first panel right is crucial.
  • Fastening and Overlapping: Panels are secured with the appropriate fasteners—gasketed screws for exposed systems or hidden clips for standing seam. Screws must be driven straight and snug to seal the washer without damaging the panel. Each subsequent panel is then carefully overlapped and interlocked with the previous one.
  • Cutting Panels: We use metal shears or a specialized blade to make cuts for angles and around obstacles. It’s vital to immediately clean all metal shavings from the roof surface to prevent them from rusting and staining the new panels.

Step 4: Finishing with Ridge Caps and Penetrations

These final touches complete the weatherproofing of your roof. We install flashing boots around all penetrations (pipes, vents, etc.) and seal them tightly. Before installing the ridge cap at the peak of the roof, we place foam closure strips along the top edge of the panels to block out pests and wind-driven rain. The ridge cap is then centered and securely fastened. Finally, we conduct a thorough inspection of the entire roof, checking all fasteners and seals and cleaning the surface of any debris. You can see examples of our meticulous work in our Project Gallery.

Deciding between a DIY project and hiring a professional is one of the most important choices you’ll make. While saving on labor costs is tempting, metal roof installation is a complex task where mistakes can be costly and dangerous.

The Rewards and Risks of a DIY Metal Roof Installation

The main appeal of DIY is saving on labor costs. However, the risks are significant:

  • Major Safety Risks: Working on a roof with large, slippery metal panels is inherently dangerous. Falls are a leading cause of injury, and professionals use specialized fall protection equipment.
  • Lack of Experience: Proper installation requires specific techniques for cutting, flashing, and fastening. Mistakes can lead to leaks, panel damage, and voided material warranties.
  • Time and Effort: A professional crew can finish in days what might take a DIYer weeks, all while handling heavy, unwieldy materials.

Frequently Asked Questions about Metal Roofs

It’s natural to have questions when you’re considering a big investment like a new roof. Here are answers to some of the most common questions we receive about metal roofs.

How long does a metal roof last compared to asphalt shingles?

A professionally installed metal roof can last 40 to 70 years, sometimes even longer. This is two to four times the lifespan of a typical asphalt shingle roof, which usually needs replacement every 15-20 years. While the initial cost is higher, the incredible longevity makes metal a more cost-effective and environmentally friendly investment in the long run.

Can a metal roof be noisy in the rain?

This is a common myth. When installed correctly over a solid roof deck with proper underlayment and attic insulation, a modern residential metal roof is no louder during a rainstorm than any other roofing material. The layers underneath effectively muffle the sound of rain, so you won’t hear that “tin can” effect.

Does a metal roof affect cell phone reception?

It’s highly unlikely. While any metal can technically interfere with radio signals, it’s rarely a noticeable issue in modern homes. Factors like your home’s construction materials, certain types of insulation, and your distance from the nearest cell tower have a much greater impact on reception. Most homeowners notice no difference in their signal after a metal roof installation.

Conclusion: Protect Your Home with a Flawless Installation

A metal roof is truly a fantastic choice for your home. It offers incredible performance for decades, adds beauty, and gives you real peace of mind. But here’s the honest truth: even the best metal roof won’t perform its best without a top-notch installation. A flawless, professional job ensures every single part works together perfectly. This creates a watertight, super durable, and long-lasting roof system for your home.
