How To Install Metal Roofing Over Shingles The Right Way?

29 August 2025

Today’s topic: How to install metal roofing?

If you’ve been thinking about upgrading your roof without tearing everything off first, you’re not alone. One of the most common questions I hear as a roofer is: “Can you put a metal roof over shingles?” The answer is yes—you can, and when it’s done right, it can save you time, money, and a whole lot of mess.

I’ve spent years working on both residential and commercial roofing projects, and I can tell you there’s a right way and a wrong way to tackle this job. Let me guide you through the process step by step, with a few pro tips and common mistakes to avoid along the way.

Why Should You Consider Installing Metal Roofing Over Shingles?

Metal roofs have gained significant popularity over the past decade, and for good reason. They’re durable, energy-efficient, and they look sharp on just about any home or building. By installing metal roofing over shingles, you:

Save on tear-off costs (no dumpster rentals or labor for removing shingles).
Add an extra layer of insulation, which can help with energy efficiency.
Reduce installation time, since you’re working over an existing roof deck.

That said, this method isn’t right for every roof. Before you start, it’s essential to ensure that your roof structure can handle the added weight and that your local building codes permit this type of installation. Additionally, you may want to consider checking out Cleveland roofing companies, thanks to their reputation and expertise, especially if you are located in the United States.

How To Install Metal Roofing Over Shingles?

So, without wasting time, let’s find out how you can install metal roofing over shingles.

Step 1: Inspect Your Roof Before Doing Anything

Here’s the truth: the success of your metal roofing project depends on the prep work. Before laying down panels, conduct a thorough inspection.

Inspect the decking for signs of rot or soft spots. If your roof sheathing is compromised, it needs to be replaced.
Look for more than two layers of shingles. Most codes don’t allow more than two layers total.
Check flashing, chimneys, and vents for proper installation. Any existing leaks must be repaired before the new roof is installed.

Pro Tip: Walk the roof carefully. If you feel any spongy areas underfoot, you have decking issues that must be addressed first.

Step 2: Lay Down A Moisture Barrier

Although shingles already provide some protection, you’ll want to add a layer of underlayment before installing metal panels. This extra layer protects against condensation that can form under the metal.

I usually recommend using a high-quality synthetic underlayment. It’s lightweight, tear-resistant, and holds up better in the long run compared to traditional felt paper.

Step 3: As An Optional Step, Add Furring Strips

This is one of those “pro versus DIY” differences. Many homeowners skip this step, but furring strips (also called purlins) create a flat, even surface for the metal panels to sit on. They also improve ventilation, which helps reduce moisture buildup under the roof.

Install the strips vertically, spacing them every 2 feet or so.
Make sure they’re fastened securely into the rafters, not just the shingles.

Pro Tip: Furring strips are especially important if your shingles are uneven or curling. Without them, your new metal roof could end up looking wavy.

Step 4: Choose The Right Metal Panels

Not all metal roofing is created equal. The most common options are:

Corrugated panels: Budget-friendly and great for sheds or garages.
Standing seam panels: Sleek look, hidden fasteners, and very durable—perfect for homes and commercial buildings.
Metal shingles or tiles: Designed to mimic traditional roofing but with the strength of metal.

Your choice ultimately depends on your budget, style preferences, and the desired lifespan of the roof. Personally, I recommend standing seam if you’re planning to stay in your home for the long haul.

Step 5: Install The Metal Roofing Panels

Now comes the main event. Installing metal roofing over shingles isn’t overly complicated, but it does take precision.

Start at the bottom edge (eaves) and work upward.
Lay the first panel square with the edge of the roof. If your first panel is crooked, the entire roof will appear uneven.
Overlap panels properly—follow the manufacturer’s guidelines for overlap distance.
Fasten with the right screws. Use screws with rubber washers to seal holes, ensuring they penetrate solid decking or furring strips.
Continue up the roof, checking alignment every few rows.

Pro Tip: Don’t overtighten screws. If the rubber washer is squished too flat, it won’t seal properly and may crack over time.

Step 6: Flashing And Trim Work

This is where many DIY jobs go awry. Flashing around chimneys, skylights, and valleys is critical for keeping water out. Trim pieces at the ridges and edges give the roof a finished, professional look.

If you’re unsure about flashing details, this is the step where you may want to consider hiring a professional. A metal roof is only as good as its weakest point, and improper flashing is the most common cause of leaks.

What Are The Common Mistakes To Avoid?

I’ve seen many metal roofs fail due to simple errors. Here are the top mistakes to watch out for:

Skipping the underlayment. This leaves your roof vulnerable to condensation.
Using the wrong fasteners. Nails or cheap screws won’t hold up—always use roofing screws with rubber washers.
Poor alignment. Once panels are on, it’s tough to fix crooked lines. Take your time.
Ignoring ventilation. Without proper airflow, you risk moisture damage and reduced lifespan of your roof.

How To Maintain Metal Roofs? Tips

Now that you know how to install metal roofing, the next issue is: how to maintain it? One of the perks of a metal roof is its low maintenance, but that doesn’t mean zero maintenance is required.

Inspect screws and fasteners yearly. Tighten or replace any that have loosened.
Keep gutters clean. This prevents water from backing up and damaging flashing.
Trim overhanging branches. Metal roofs are tough, but falling limbs can still cause dents or scratches.
Wash occasionally. A simple rinse with a hose keeps the roof looking sharp and removes debris.

Know How To Install Metal Roofing In 2025!

If you’re handy and comfortable working on a roof, installing metal over shingles is a doable task. But here’s my honest advice: it’s not for everyone. Working on a roof is inherently dangerous, and even a minor mistake can result in significant financial consequences down the road.

As a roofer, I’ve fixed plenty of DIY jobs that started with good intentions but ended up leaking or looking crooked. If you’re unsure about any part of the process—especially flashing and sealing—don’t be afraid to call in an expert.

Installing metal roofing over shingles can be a smart move if it’s done right. You’ll save money, boost curb appeal, and enjoy a roof that could last 40–50 years.

If you’re ready to take the next step, don’t hesitate to reach out to a professional roofer. Whether you just need advice, an inspection, or a full installation, we’re here to help. After all, a roof isn’t something you want to gamble on—it’s what keeps your family, your business, and everything inside safe and dry.

5 Money-Saving Tips for Houston Drivers

Purchasing cheap car insurance in Houston need not be such a chore. With increasing expenses and Houston's specific road hazards, many Houston motorists are in search of options in an effort to minimize their monthly expenditures. Luckily, there are some sound money-saving driving tips that will help Houston motorists minimize their premiums without compromising on necessary coverage. Car insurance will protect you financially when you drive. It is necessary that you make sure you are getting the best deal possible, whether you are choosing some of the basic liability insurance or full auto coverage. Understanding Houston's Unique Insurance Landscape Houston does pose some challenges to drivers and to insurers as well. Houston's size results in most of its people having a longer drive to work, and the Gulf Coast placement provides seasonal weather-related risks. Its traffic is among the worst in the country, and all of these have an impact on insurance rates throughout the metroplex. The good news? Those who understand these factors can make smarter choices about their coverage and might qualify for reduced rates. Info is power when purchasing cheap car insurance Houston. Money-Saving Driving Tips: Smart Ways to Save on Auto Coverage Before discussing money-saving driving tips and car insurance, you should know that personal driving habits play an important role in determining the amount of gas or other safety equipment that you need. Here are the things that can save you a hefty amount. 1. Shop Around Before Renewal Time One of the largest errors Houston drivers commit is renewing automatically with their existing agent without comparing competitors' prices. Insurance firms use various formulas to calculate premiums, thus premiums can be widely varied among companies for similar coverage. Set a calendar reminder 3-4 weeks before your policy expires to compare quotes from multiple companies. This simple habit could save hundreds of dollars annually. Many local providers offering Houston car insurance have competitive rates that national companies can't match. 2. Adjust Your Coverage Based on Vehicle Value If your vehicle is an older model, you could be paying too much for coverage that you do not require. For vehicles worth less than $4,000, collision and comprehensive coverage will cost you more in the long run than the possible payout for an accident. Consider canceling these coverages on older cars and retaining only liability coverage, which is still mandated by Texas law. This approach will be especially well-suited for households with multiple vehicles, where one may be a whole lot older than others. 3. Take Advantage of Available Discounts Most insurance providers offer discounts that many customers never claim simply because they don't know about them. Common discounts include: Safe driver discounts (for accident-free records) Multi-policy bundles (combining home & auto insurance) Good student discounts (for young drivers maintaining solid grades) Professional organization memberships Paperless billing and automatic payment enrollment Defensive driving course completion These discounts can stack up, potentially reducing premiums by 15-25% when combined. Ask your agent for a comprehensive list of available discounts and which ones you qualify for. 4. Increase Your Deductible Strategically Your deductible—the amount you pay yourself before insurance comes in—also plays a role in your premium. Increasing your deductible from $500 to $1,000 will decrease your premium by 10-15%. Though this should be done judiciously, raise your deductible only to what you can afford in case of an emergency. Saving the premium charge difference in a special savings account provides a buffer for possible payment of the deductible and lower monthly premiums. 5. Improve Your Credit Score Although it has absolutely no bearing on driving, Texas insurers can utilize credit scores in their calculation of premiums. Studies indicate that high-credit drivers are more likely to be claim-free, and hence lower premiums result. Small gains to your credit can pay big dividends in terms of insurance savings over the long term. Prioritize making on-time payments, lowering your current debt, and disputing any inaccuracies on your credit report. Even a 50-point boost in your credit score could lead to visible premium decreases. Finding the Right Local Provider Now that you know the best money-saving driving tips, you should find a local provider. Location is significant when choosing an insurance company. Insurers with real offices in Houston will be more aware of local road conditions and may have better-suited coverage options. For example, rush hour traffic congestion on I-610 or flooding problems within specific neighborhoods might lead to coverage recommendations. Local agents particularly familiar with Houston's unique issues are better positioned to tailor policies to also cover such niche risks. The majority of Houstonians enjoy working with companies with local offices. The office at 156 FM 1960 Ste F reflects many North Houston communities with personalized service, which national call centers can only aspire to offer. The Bottom Line for Houston Drivers Purchasing cheap vehicle insurance is all about striking a balance between paying and coverage. One has to save money, but underinsurance can bring ruin in its wake after a bad crash. The ideal solution is a mix of cost-cutting approaches without compromising sufficient protection for your particular case. Allowing an hour or two of research can help you with money-saving driving tips, without compromising enough coverage. Houston drivers are also challenged, but with a bit of research and the right carrier, quality insurance doesn't have to be pricey. Take a few minutes to dig into your policy, ask questions about discounts available, and consider whether providers in your region might be more valuable than their national relatives. Keep in mind that insurance requirements change along with you. Life events such as marriage, home ownership, or adding a teenager to your policy are great times to review coverage to make sure you are getting the most bang for your buck.

Why Your Phone’s Signal Varies from Room to Room: A Guide to Radio Waves

Have you ever wondered why the phone signal works perfectly fine in the living room, but struggles to load a simple WhatsApp message on the other side of the room or in the extreme corners of your house? One minute, you are enjoying a strong network connection, and the next, you are walking around your room, waving your phone in the air to catch the signal. The inconsistency in the networking connection is not just some ordinary internet problem; it has a lot to do with radio waves and how wireless signals behave indoors. From Wi-Fi calling to wireless signals, this article will uncover all the reasons does phone signals vary so drastically from one room to another. What are wireless signals? Wireless signals are invisible waves or electromagnetic waves that transmit data through the air. These signals travel freely between devices instead of needing a physical connection to transfer data. But the strength of these radio waves can vary depending on several factors. The fluctuations of your phone network from one room to another depend on how strong and uninterrupted these waves are. This is also applicable if you are using a mobile hotspot connection to operate your digital devices. For instance, if you invest in a reliable and globally recognised telecom operator like Vi Prepaid or Postpaid service, you might not have to worry about dealing with poor internet connections, as they will have their own networking towers installed across the city and other places in your state or country. However, it is important to understand the features, data plans, and service quality before committing to any telecom operator. When you opt for a reliable telecom operator like Vi, you get access to unlimited calling, fast internet connection, data rollover, and other exciting features that help enhance your overall networking experience. Now, let us look at the factors that influence signal strength fluctuations. 1. Walls can weaken the signals Believe it or not, but walls in your home can also play a key role in interfering with and fluctuating the radio waves. Not all walls are made equally. Thick concrete walls, brick structures, and walls reinforced with metals can often weaken the wireless signals. Hence, you may also notice a drop in your signal the moment you step into another room or rooms with fewer windows. 2. Keep the windows open The farther your phone is from networking tower, the more challenging it is for it to maintain a strong connection. Consider keeping the windows of your room open while using the networking services. You also consider sitting close to your windows while working online or using internet. This way, you can enjoy the outdoor view and while suffering on the net. 3. Outdated Wi-Fi router One of the most common reasons why your router might not offer desired network connectivity is because it lacks modern features and is unable to support the increased demand for internet usage and WiFi calling. So, if you have the same internet router for a couple of years or for a decade, it's time for an upgrade. 4. Building design Many might not be aware, but building infrastructure can present challenges for smooth and swift transmission of radio waves from one end to another. Sometimes, even energy-efficient windows with metal coatings can reflect radio waves from passing through easily. As mentioned above, try to keep your windows open while using your internet or network services. Conclusion: Frequent fluctuations or variation of phone signal from one room to another can be super annoying. Hopefully, this article helped you understand the several reasons that affect the radio waves and why phone signal may vary throughout your flat or living spaces. Switch to reliable telecom operators and keep your windows open while using the internet to enjoy fast internet and networking experience.
