When it comes to roofing, one of the most important steps in the process is installing the underlayment. This material layer goes on top of the roof deck and underneath the shingles or other roofing materials. One of the most commonly used underlayment materials is 30lb felt paper. However, when it comes to installing this material, one of the most common questions we get from clients is, “What size staples do I need?”
As a specialist roofing contractor with over 10 years of experience, TDH Contracting has the knowledge and expertise to answer this question and provide guidance on proper staple size and technique for installing 30lb felt paper.
In this article, we’ll cover everything you need to know about staples for 30lb felt, including proper size, installation techniques, and other options for fasteners.
What Size Staples For 30lb Felt?
When it comes to choosing the proper size staples for 30lb felt paper, there are a few things to consider. First and foremost, the staples must be strong enough to hold the felt paper in place securely, but not so long as they penetrate through the roof deck. Generally, 3/8-inch crown staples with a 1-inch length are the most commonly used for 30lb felt paper.
| Crown Size | Length | Recommended Use |
|---|---|---|
| 3/8 inch | 1 inch | Thin felt and low substrate thickness |
| 3/8 inch | 1-1/4 inch | Thin felt and low substrate thickness |
| 1/2 inch | 1 inch | Thicker felt and moderate substrate thickness |
| 1/2 inch | 1-1/4 inch | Thicker felt and moderate substrate thickness |
These staples are strong enough to hold the material in place without causing damage to the underlying structure. However, it’s always a good idea to check with your roofing material manufacturer to ensure that the staple size and installation method you plan to use are compatible with their product.
Can You Staple Roofing Felt?
Yes, you can staple roofing felt. In fact, using a staple gun is one of the most common methods for installing 30lb felt paper on a roof. Staples provide a fast and secure way to tack down the material, and they are easy to install with the right equipment. However, it’s important to make sure that the staple size and spacing are appropriate for the type of felt paper you are using. As we mentioned earlier, 3/8-inch crown staples with a 1-inch length are generally the best choice for 30lb felt paper, but always check with your material manufacturer to ensure compatibility.
Additionally, proper staple spacing is important to ensure that the felt paper is held in place evenly and securely. Most roofing contractors recommend spacing staples 4-6 inches apart along the length of the material, and 12 inches apart across the width.
How Many Staples For Roofing Felt?
The number of staples needed for roofing felt can vary depending on the size of the roof and the spacing of the staples. However, a good rule of thumb is to use approximately 400 staples per roll of 30lb felt paper. This equates to about 4 staples per linear foot of material.
Of course, if you are working with a particularly large or complex roof design, you may need more staples to ensure that the felt paper is held securely in place. Additionally, if you are using a staple gun with a smaller magazine capacity, you may need to reload frequently to ensure that you have enough staples on hand to complete the job. It’s always better to have extra staples on hand than to run out mid-project.
What are 3/8 Crown Staples used for?
3/8-inch crown staples are a versatile type of fastener that can be used for a wide range of construction and DIY projects. These staples get their name from the width of the staple crown, which measures 3/8 of an inch. Here are some common uses for 3/8 crown staples:
Upholstery: 3/8-inch crown staples are commonly used in the upholstery industry to secure fabric to frames, foam to frames, and foam to foam. The staples are strong enough to hold the materials in place but not so long that they damage the underlying structure.
Carpentry: 3/8-inch crown staples are often used in carpentry applications to fasten wood trim, molding, and other decorative elements to walls and ceilings. They can be used in conjunction with a staple gun or pneumatic stapler for quick and easy installation.
Roofing: As we mentioned earlier, 3/8-inch crown staples with a 1-inch length are commonly used for tacking down 30lb felt paper during roofing projects. These staples are strong enough to hold the material in place but not so long that they penetrate through the roof deck.
Overall, 3/8 crown staples are a versatile and reliable fastening solution that can be used in a variety of applications.
How Thick and Big are 3/8 Crown Staples?
3/8 crown staples are a type of staple that gets its name from the width of the staple crown, which measures 3/8 of an inch. The thickness of 3/8 crown staples can vary depending on the manufacturer and the intended use, but they are typically made from wire that is 18 gauge or 19 gauge. The length of 3/8 crown staples can also vary, ranging from 1/4 inch to 1 1/2 inches or more, depending on the specific application.
It’s important to choose the right staple length for your project to ensure that the staples are long enough to hold the materials in place but not so long that they penetrate too far or damage the underlying structure.
Heavy-Duty Staple Gun For Felt Paper
A heavy-duty staple gun is an essential tool for any construction project, especially when it comes to roofing and felt paper installation. When selecting a staple gun for felt paper, it’s important to choose one that can handle the thickness and durability of the materials. Look for a staple gun that is specifically designed for roofing or construction applications and has a high enough capacity to handle the number of staples you’ll need.
One option to consider is the Arrow T50 Heavy Duty Staple Gun, which is a popular choice among contractors and DIY enthusiasts alike. This staple gun is designed to handle a variety of materials, including felt paper, and has a high capacity for holding staples. It also features a jam-resistant mechanism and durable all-steel construction, making it a reliable choice for tough jobs.
Another option is the Bostitch Heavy Duty Staple Gun, which is designed specifically for roofing applications. This staple gun can handle both 18-gauge and 16-gauge staples, making it versatile for different materials and thicknesses. It also has a high-capacity magazine and a comfortable grip, making it easy to use for extended periods of time.
Installing Roofing Felt With Staples vs. Nails
When it comes to installing roofing felt, one common question that arises is whether to use staples or nails. Both staples and nails can be effective in securing the felt to the roof, but there are some key differences to consider.
Staples are often preferred for their speed and ease of use. A staple gun can quickly fire multiple staples, allowing for efficient installation. Staples are also less likely to damage the felt paper than nails, which can sometimes tear or create holes. Additionally, staples are less likely to back out over time, providing a more secure hold.
On the other hand, nails are generally considered to provide a stronger hold. They can penetrate deeper into the substrate and have a larger surface area to grip onto the felt paper. Nails can also be more resistant to wind uplift, making them a better choice in areas with high winds. However, nails can also cause more damage to the felt paper if not installed properly, and may require more time and effort to install.
Conclusion
In conclusion, selecting the right staple size and type is an important consideration for any construction or DIY project. When it comes to the roofing felt, 3/8 crown staples with a 1-inch length are a reliable and effective option for tacking down 30lb felt paper. However, it’s important to consider other factors such as the staple gun or pneumatic stapler you’ll be using, the spacing of the staples, and the materials you’ll be working with.
By taking the time to choose the right staples and using proper stapling techniques, you can ensure a successful and long-lasting roofing project. Whether you’re a DIY enthusiast or a professional contractor like TDH Contracting, having a good understanding of staple sizes and their applications is an essential part of any construction project.
