The Benefits of Metal Roofing

When installing a new roof, it’s important to do your research on the different materials that are available. Your decision about what kind of roof to install should take a variety of factors into account, including service life, efficiency and appearance. You should also do the math on the installation, material and maintenance costs for each option.

Many homeowners are finding that there are several convincing reasons to choose a metal roof over a more traditional asphalt shingle roof. Here are some of the benefits of a metal roof.

Superior Longevity: A metal roof can last anywhere from 40 to 70 years, depending on the materials and your location. An asphalt shingle roof, on the other hand, usually needs replacement after 15-20 years.
Reduced Maintenance: While asphalt shingles can be blown away by strong winds or eroded by the elements, a metal roof is a solid, sturdy match for even the harshest climates.
Sustainability: Not only are most metal roofing materials recyclable, but they save energy. A metal roof reflects the sun's rays, meaning less heat is absorbed into your home during the warmer months.

Some homeowners decide against a metal roof because of the higher cost upfront. The materials and installation tend to be pricier than asphalt shingles. But if you plan to stay in your home for several decades, you can save in the long run, since a metal roof tends to last much longer than an asphalt one. A quality roof can also increase the resale value of your home.

Deciding Between a Do-It-Yourself Job and a Pro Install

Even for the handiest of homeowners, installing a new roof is a tricky job. It’s time-consuming, demanding and potentially dangerous, so it’s important to know what you’re getting into before you do it yourself.

The first factor to consider is the size of the roof that needs to be installed or replaced. While putting a roof on a two-story home might be best left to the pros, installing new roofing on a shed, playhouse or detached garage may be doable for an experienced do-it-yourselfer. You should also consider the overall complexity of the job. A simple A-frame roof would be much easier to install than a roof with complex angles or features like skylights and dormers. Be sure to take into account any obstacles such as overhanging trees or powerlines as well.

The bottom line? Be sure that you know what the job entails and that you have the necessary skills and materials to complete it safely. This guide outlines the basic steps involved in installing a roof, but you may need to do additional research or hire qualified professionals to complete the work.

If you decide to entrust the job to a pro, Lowe’s can help with installation.

Choosing Metal Roofing Materials

Lowe’s carries many different metal roofing materials to satisfy different tastes, budgets and appearance requirements. Here are some of the most popular materials.

Steel: Steel is affordable and durable, even in tough climates. It’s usually painted or coated to protect it from rust and improve its appearance.
Aluminum: Aluminum is a bit more expensive than steel, but it’s also more corrosion-resistant in areas near the ocean.
Copper: Copper is a very attractive roofing material, but also the most expensive option. It develops a rich green patina over time.
Zinc: Zinc roofing is naturally weather-resistant and moldable, so it's easy to work with and great for creating different designs.

These materials come in a few main formats that are useful for different applications.

Corrugated metal panels are very common. These wavy metal sheets are often used on barns, sheds and outbuildings.
Modular panels and standing-seam roofs are very durable and come in a variety of materials and designs for homes and industrial buildings.
Metal shingles look like their asphalt counterparts but offer the superior durability of metal.

Step-by-Step Metal Roofing Installation

If you decide to install a roof yourself — or if you just want an idea of what to expect when the pros come — you can follow these basic steps to get started.

Caution

Roofing can be dangerous, particularly on tall buildings. Always take proper precautions to prevent slips and falls, and do not work in bad weather. Look out for overhanging power lines. Be sure to wear appropriate clothing and shoes and use protective equipment.

Good to Know

Always be sure to follow local building codes, and check to see if a permit or inspection is required before beginning work.

Instructions

Step 1: Take Measurements and Buy Metal Roofing Materials

When you budgeted out your project, you probably made a loose estimate of the area of your roof. But when it’s time to buy materials and begin the installation, you’ll need a more exact measurement.

For a basic gable roof, multiply the length of the rake (the line from the top ridge to the eaves) by the distance from eave to eave. Double this to get the total square footage.
If your roof has features such as skylights or dormers, measure these separately and add them in to your total.
Order 10% extra to account for waste.

Tip

Draw a simple diagram to record the measurements so you can refer back to it as you work.

Step 2: Remove the Old Materials and Make Structural Repairs

Step 3: Install Underlayment

Step 4: Install Drip Edge Flashing and Closure Strips

Step 5: Install Corrugated Metal Roofing Panels

Step 6: Install Closure Strips and the Ridge Cap

Increase the Comfort and Value of Your Home

Investing in a new metal roof will make a big difference in the comfort and value of your home. Once your new roof is in place, your home’s exterior will have an updated look — and you can rest easy knowing that your house is protected for years to come.

How Do Polycarbonate Roof Panels Differ from Metal Roof Panels?

Polycarbonate panels used as a sunroom ceiling.

Polycarbonate panels are a type of plastic roof panels designed for structures like patios, sunrooms and carports. They’re also used as skylights in certain applications. One advantage of polycarbonate roof panels is that they allow sunlight in while blocking UV radiation, which can be harmful to the skin. Polycarbonate sheets and panels are available in clear and opaque varieties, depending on how much natural light you want in the space. Another major advantage of polycarbonate is its flexibility, which means it can be curved or arched for use in structures such as covered walkways, canopies and awnings. Polycarbonate is also a popular building material for greenhouses and pool coverings.
