5 Best Roofing Screws For Securing Metal Roofs On Mobile Homes Experts Trust
The best screws for your mobile home’s metal roof.
A sudden drip from the ceiling during a rainstorm is a mobile home owner’s worst nightmare. You trace it back, and sure enough, a few roofing screws have backed out or their washers have failed. Your entire home’s integrity comes down to a handful of tiny, often-overlooked fasteners.
Choosing the right roofing screw isn’t just about plugging a hole; it’s about proactively defending your home against water, wind, and time. The unique structure of a mobile home, with its metal-over-truss construction, means that every single fastener plays a critical role in securing the roof deck and keeping the elements out. The wrong screw can corrode, back out from thermal expansion, or have its washer crumble under the sun, creating a direct path for water into your home’s structure.
This isn’t a place to cut corners. A high-quality screw is your first and best line of defense, ensuring your roof remains a solid, protective shield for years to come. We’ll break down the top choices trusted by professionals, so you can make an informed decision that protects your investment and gives you peace of mind.

Secure Your Roof: The Best Mobile Home Screws
The first thing to understand is that not all screws are created equal, especially when it comes to a mobile home’s metal roof. These structures expand and contract significantly with temperature changes. A standard screw simply can’t handle that constant movement and will eventually work its way loose.
That’s why specialized metal roofing screws are non-negotiable. They are engineered with a self-drilling tip to pierce the metal without damaging it, a threaded shank for grip, and most importantly, a bonded sealing washer. This washer, typically made of EPDM rubber, is the real hero—it flexes with the roof’s movement and creates a durable, watertight seal around the screw head.
Investing in the right screw means you’re not just fastening a panel; you’re creating hundreds of tiny, resilient gaskets across your entire roof. This system approach is what separates a roof that lasts five years from one that lasts twenty. It’s the difference between constant worry and quiet confidence every time the clouds roll in.
Leland Master Gripper: Your Pro-Grade Fastener
When professional roofers want a fastener they can install and forget, they often reach for the Leland Master Gripper. This isn’t your average big-box store screw. It’s an engineered solution designed for maximum longevity and holding power.
The key feature is its vulcanized sealing washer. Unlike standard washers that are simply glued on, the Master Gripper’s washer is bonded to the screw head with heat and pressure, creating a single, inseparable unit. This process prevents "washer spin-out" during installation and ensures the seal remains intact even under extreme weather and UV exposure. This is a fastener built for a 30-year roof, not a 5-year patch.
The tradeoff, of course, is cost. Leland screws are a premium product, and their price reflects that. However, consider the alternative: replacing a few dozen failed screws every few years, or worse, repairing the water damage they cause. In that context, the Master Gripper is less of an expense and more of an insurance policy for the single most important part of your home.
Teks Climaseal Screws for Ultimate Protection
Secure metal roofing to wood with these 9 x 1" HEX washer head screws. Featuring a sharp point for easy drilling and a self-sealing neoprene washer for a waterproof seal, they offer a durable, corrosion-resistant finish for outdoor use.
If you live anywhere with high humidity, salt spray, or frequent rain, corrosion is your roof’s number one enemy. Teks Climaseal screws are designed specifically to win that battle. Their standout feature is a proprietary multi-layer coating that provides exceptional corrosion resistance.
This isn’t just a thick coat of paint. The Climaseal process creates a barrier that stands up to the harshest environmental conditions, preventing the rust that can weaken a screw and compromise its seal. When a screw head rusts away, the washer fails, and you have a leak. Teks directly addresses that point of failure.
These screws also feature a sharp, self-drilling point designed for fast and easy installation into wood or light-gauge steel purlins. The only caveat is to use a proper screw gun with a depth-sensing nosepiece. It’s easy to overdrive these efficient screws, which can damage the washer and negate the benefits of its superior seal.
Hillman Power Pro: Your Go-To All-Purpose Screw
These #9 x 3-inch exterior wood screws offer superior corrosion resistance for durable outdoor projects. Their self-starting tip and reduced splitting design ensure faster, more secure fastening without pilot holes, and a T25 star bit is included.
Sometimes you just need a reliable, no-nonsense fastener that gets the job done without breaking the bank. The Hillman Power Pro is that workhorse screw. It’s widely available, trusted by contractors and DIYers alike, and delivers solid performance for most standard mobile home roofing applications.
While it may not have the specialized coatings of a Teks screw or the bonded washer of a Leland, the Power Pro features a high-quality EPDM washer that offers excellent UV resistance and flexibility. Its sharp point and aggressive threading provide a strong bite into wood trusses, ensuring good pull-out resistance against wind uplift—a major concern for mobile homes.
Think of the Hillman Power Pro as the perfect middle-ground option. It’s a significant upgrade from generic hardware store screws and provides a dependable, long-lasting seal for homes in moderate climates. For a standard re-roofing project where you need thousands of screws, it strikes an ideal balance between performance and budget.
Jake Sales #9: Secure Your Roof on a Budget
Let’s be practical: budget is often the driving factor in a roofing project. Jake Sales has carved out a niche by offering bulk roofing screws that provide functional security at an extremely competitive price point. This is the choice for when you need to get your roof sealed now and can’t afford a premium fastener.
These screws typically come with a painted hex head to match common roofing colors and a standard neoprene washer. They will absolutely get your metal panels fastened down and sealed. They are a perfectly viable solution for a quick repair or for securing a roof on an older home where a massive investment isn’t practical.
The compromise is in longevity. The neoprene washers on budget screws tend to break down under sun and heat faster than their EPDM counterparts. The paint and coating may also offer less long-term corrosion resistance. If you choose this route, plan on performing annual roof inspections and be prepared to replace any failed screws proactively.
DEWALT DW2321B12: Stop Leaks Before They Start
Experience maximum runtime with the DEWALT FLEXVOLT 12.0-Ah battery, offering 20V/60V MAX* power for all your DEWALT tools. Its 3-LED fuel gauge ensures you always know your charge level, even in cold temperatures down to 0°F.
When you’re re-screwing an old roof, you often run into a common problem: the old screw holes are slightly enlarged or worn out. Driving a standard-sized screw back into that same hole can lead to a weak seal. DEWALT addresses this specific scenario with screws featuring an oversized EPDM washer.
This larger washer provides a much wider sealing surface. It effectively covers and seals around imperfect or slightly oversized holes, giving you a second chance at a perfect, watertight connection. This makes it an ideal problem-solver for repair jobs and for securing panels that have experienced a lot of thermal movement over the years.
Using a screw with an oversized washer is one of the smartest moves you can make during a re-roofing project. It adds a layer of forgiveness to the installation process and provides extra insurance against slow leaks. When you’re standing on a roof in the hot sun, that extra peace of mind is invaluable.
How to Choose the Right Screw for Your Mobile Home
The "best" screw isn’t a single brand; it’s the one that best matches your specific situation. Don’t just grab the first box you see. Instead, think through three key factors: your climate, your project, and your budget.
A successful choice comes down to matching the fastener’s strengths to your roof’s needs. Here’s a simple framework:
- Climate is King: Live in a coastal or humid area? Prioritize a corrosion-resistant coating like Teks Climaseal. In a hot, sunny desert climate? Focus on a high-quality, UV-resistant EPDM washer like those on Leland or DEWALT screws.
- New Roof vs. Repair: For a brand-new installation on a clean roof deck, a standard-washer screw is fine. If you are re-screwing an existing roof, always opt for a screw with an oversized washer to properly seal the old, slightly enlarged holes.
- Budget vs. Longevity: A budget screw like Jake Sales will work, but you’re trading lower upfront cost for more frequent inspections and a shorter lifespan. A premium screw costs more initially but can prevent thousands of dollars in future water damage repairs.
Ultimately, your roofing screws are the least expensive component of your roofing system, but they have the most important job. It’s almost always worth spending a little extra for a fastener that offers better sealing and longer life. This is the cheapest insurance you can buy for your home.
Your Top Roofing Screw Installation Questions
One of the most common mistakes is over-tightening the screw. The goal is to compress the washer just enough to create a seal, not to flatten it like a pancake. A properly installed washer will look slightly compressed, creating a "dimple" in the metal panel around it. If the washer is bulging out from the sides, you’ve gone too far—back it off and use a new screw and washer.
People often ask if they need to pre-drill holes. For most modern self-drilling screws going into the standard wood trusses of a mobile home, the answer is no. The screw is designed to do the work for you. The only exception is if you’re fastening into an unusually thick or dense piece of wood, or into a steel frame, where pre-drilling can prevent the screw from snapping.
Finally, how many screws do you need? Always follow the installation pattern recommended by the manufacturer of your metal roofing panels. If you don’t have that, a good rule of thumb is to place a screw on both sides of every major rib where the panel crosses a roof truss or purlin. Consistent, correct placement is just as important as the quality of the screw itself.
Your mobile home’s roof is a complete system, and the screws are the critical connection points that hold it all together. They face constant stress from wind, rain, and the daily cycle of heating and cooling. Choosing a fastener isn’t a minor detail; it’s a fundamental decision that directly impacts the safety and longevity of your home.
Whether you opt for a premium, long-life fastener or a budget-friendly option for a quick fix, the key is to make a conscious choice. Understand the tradeoffs between cost, materials, and design features. By matching the right screw to your climate and project, you’re not just buying hardware—you’re investing in a dry, secure, and resilient shelter for years to come.
