Delmarva Metal Roofing


For metal roofing to be durable and long-lasting on the East Coast, using the right type of screws is essential. Apart from holding the metal panels in place, they are crucial for preserving the roof\’s overall structural integrity. As a reliable roofing company serving homeowners in Baltimore, Maryland, we recognize the importance of using high-quality screws for metal roofing installations and repairs. In this blog post, the various screw types used in East Coast metal roofing will be discussed, along with details on their distinctive look and characteristics and advice on how to select the best ones for your metal roofing project.

Self-Drilling Screws

Self-drilling screws also referred to as self-tapping screws, are a common option for installing metal roofing. They have a sharp point that allows them to drill into metal without needing pre-drilling holes. The drill point ensures a secure connection between the metal panels and the underlying structure by creating a snug fit. Self-drilling screws save time and effort during installation, making them popular among roofing contractors.

Galvanized Screws

Zinc coating on galvanized screws makes them extremely rust and corrosion-resistant. Galvanized screws must be used to ensure the metal roofing\’s durability due to the East Coast\’s exposure to moisture and salt water. The zinc coating acts as a barrier to shield the metal panels from damaging environmental elements and prevents screws from reacting with them.

Stainless Steel Screws

Stainless steel screws are another excellent option for Baltimore, Maryland, metal roofing due to their exceptional corrosion resistance. These screws are made of a steel-chromium alloy, forming a passive layer that protects the screws from oxidation. Stainless steel screws work excellently in coastal regions where the metal roof is constantly exposed to saltwater and high humidity.

Painted Screws

For visually appealing metal roof projects, painted screws are the best option. These screws are available in various colors that match the hue of the metal panel, creating a seamless appearance. The painted coating not only improves the roof\’s visual appeal but also adds a layer of protection against weather elements, extending the roof\’s life.

Neoprene Washer Screws

This type of screw has a rubber washer attached to the head. This washer seals off screw holes so that water can\’t get in. When installed correctly, neoprene washer screws protect the roof from water damage and leaks. This makes them a good choice for metal roof projects in rainy or snowy parts of the East Coast.

Stitch Screws

Stitch screws are made specially, with more than one thread on a single screw. These screws are used to fasten overlapping metal panels, making a seal that keeps water out at the joints. Stitch screws prevent water infiltration between panels and preserve the integrity of the metal roofing system during heavy rain or snowfall.

Re-Sealable Screws

Roof maintenance is critical for any metal roofing system\’s long-term performance. Re-sealable screws have a factory-applied sealant on the screw threads, which improves their water resistance. During roof inspection or repair, these screws can be unscrewed and re-tightened without losing their ability to seal. This makes them a great choice for roofing projects that need occasional adjustments or replacements.

The Benefits of Using Metal Roofing Screws Over Traditional Screws

When securing metal roof panels, using specialized metal roofing screws has several benefits over traditional screws. Let\’s consider the benefits of choosing metal roofing screws for your Baltimore, Maryland, metal roofing project.


Corrosion Resistant

Metal roofing screws are made from materials that are resistant to corrosion and rust, such as galvanized steel or stainless steel. Traditional screws, on the other hand, might not have the coatings needed to protect them from the harsh East Coast weather. Metal roofing screws have superior corrosion resistance, ensuring a longer lifespan for your roof and reducing the need for frequent replacements.

Enhanced Weatherproofing

Metal roofing screws are frequently equipped with weatherproofing features such as neoprene washers or factory-applied sealants. These components form a tight seal around the screw, preventing water infiltration and protecting your roof from leaks, even during heavy rain, hail, wind, or snowstorms. Traditional screws may not be as weatherproof, resulting in potential water damage and compromised roof integrity.

Self-Drilling Efficiency

Self-drilling metal roofing screws make installation easier because they do not require the metal panels to be pre-drilled with holes. This effectiveness decreases the possibility of installation errors while also saving time. Traditional screws, on the other hand, frequently necessitate additional steps for pre-drilling, which can be time-consuming and result in misalignment if not done correctly.

Increased Load-Bearing Capacity

Metal roofing screws are designed to outperform traditional screws in load-bearing capacity. Because of their design, style, and materials, they can securely hold metal panels in place even in high winds and severe weather. This increased load-bearing capacity ensures the structural stability of your metal roof, making it an excellent option in areas prone to hurricanes or heavy snow.

Improved Energy Efficiency

The energy efficiency of your house can be significantly increased by using metal roofing screws. Metal roofing screws ensure a secure and seamless attachment of metal panels to the roof structure. This prevents air leakage and reduces heat loss during the winter while also reducing warm air ingress during hot summer days. Your HVAC systems will therefore have to work less hard, using less energy and costing you less money.

Harnessing the Sun\’s Rays

Metal roofing screws work well with solar panel installations, particularly on standing seam metal roofs. Metal roofing screws ensure the stable placement and accurate alignment of solar arrays by securely fastening solar panels to roofs. The solar panels are strategically positioned to best capture the sun\’s rays, maximizing their capacity to produce electricity and promoting a greener, more sustainable home.

Aesthetically Pleasing

Metal roofing screws come in various colors, including those that match your metal panels. This feature ensures that the screws blend in with the roof\’s overall appearance, resulting in a polished and aesthetically pleasing finished appearance. Traditional screws, on the other hand, maybe noticeable and detract from the roof\’s visual appeal.

Cost Savings in the Long Run

Although metal roofing screws are slightly more expensive upfront than traditional screws, their longevity, and durability result in long-term cost savings. You can save money in the long run by reducing maintenance and replacing fewer items. Also, the increased weatherproofing and load-bearing capacity of metal roofing screws can protect your investment by making it so you don\’t have to fix your roof as often because of water damage or structural problems.

Tips for Proper Screw Installation

Before beginning your metal roof project, keep the following important screw installation tips in mind:

Use the Right Drill Bit

Ensure you have the right size drill bit for the self-drilling screws so you don\’t damage the metal panels and get a good fit.

Mind the Over-Tightening

Overtightening screws can distort metal panels and jeopardize their structural integrity. For torque specifications, follow the manufacturer\’s instructions.

Properly Align the Panels

During installation, take care to properly align the metal panels so that the screws penetrate the intended area, resulting in a uniform and leak-resistant metal roof.

Space the Screws Adequately

Follow the recommended spacing guidelines to guarantee adequate screw distribution for stable and sufficient load-bearing capacity.


Choosing the right screws for your Baltimore, Maryland, metal roof is critical to ensure that it\’s safe, watertight, and long-lasting. In order to meet a variety of roofing needs, self-drilling screws, galvanized screws, stainless steel screws, painted screws, neoprene washer screws, stitch screws, and re-sealable screws, all have special advantages. By thinking about the climate, roofing materials, aesthetics, and budget and getting professional advice, you can make an informed decision about how to protect your metal roof from the harshest weather.
