Sinsun is a professional felt nail factory that produces high-performance tack nails, also known as roof tacks, shingles roof tacks, and wood paper nails. These nails are made for various construction needs. We manufacture our felt nails out of high-quality carbon steel and put them through strict galvanization or coating processes. They hold woven materials firmly without causing damage. We control every step of the production process, from selecting the raw materials to inspecting the finished product. This ensures that every nail meets international quality standards and functions reliably under tough conditions. -
Sinsun stated that felt nails come in many different types, such as roofing felt nails, shed felt nails (also called shed felt tacks, shed roof felt nails, and shed roof felt tacks), and nail on felt pads (felt pads with nails). Our ability to customize our production sets us apart. We can modify the length of the nails, the size of the heads, and the surface treatment to fit the needs of your project. We test every batch of our felt nails to make sure they can withstand corrosion and pull-out strength. This makes them a reliable choice for contractors and distributors all over the world.

shed roof felt nails Key Applications (Where to Use Them)
Roofing for a garden shed
This is the most critical thing. When you re-roof a shed, the wind is not your friend. Standard wire nails will eventually come loose because they expand and contract. Sinsun's shed nails have a ring shank. It's like a ribbed anchor: once it's in, it's in. For standard 11mm OSB board, I suggest 15mm. To keep the pads waterproof, drive it flush instead of deep.
How to Use Flat Roof Felt
For big flat roofs, you have to deal with heavy mineral felt. You need roofing tacks that hold up to all that weight. Here, our 20mm galvanized large head abrasion nails are the most suitable choice. The wider head keeps the felt from "popping" off the nail when there is foot traffic during maintenance. Using our nails cuts down on callbacks for "nail pops," which is a huge pain for contractors.
Fixing the acoustic underlayment
A small but growing market. If you're putting acoustic pads under a hardwood floor to cut down on noise, you need nail-on felt pads that are short enough not to hit the concrete subfloor (if it's a suspended timber floor) but strong enough to hold. The 10mm and 12mm versions are great for this. They hold the underlayment in place without showing through the top flooring.
Sheathing and waterproof membrane
These are also felt and paper nails for wall sheathing, and roofing. You need fasteners that won't rust behind the cladding when you wrap a house in Tyvek or roofing material before siding. Our galvanized finish keeps the nails safe for the life of the building, even if moisture gets trapped in the wall cavity.
Quick Guide to Installation (Things to Do and Not Do)
I've learned from more than ten years of site feedback that the way something is installed is half of its success.
The Right Amount of space
Don't be cheap. You should use a nail every 3 to 4 inches along the edges of the roofing sheet and every 6 to 8 inches in the field. I see too many people trying to save nails by putting them further apart. You're saving a few dollars, but your roof could blow off. You can afford to nail it right at factory prices.
The Rule of overlap
There should be at least 4 inches of overlap when joining two sheets of roofing material. Push the taps for your roof through both layers. If you are using 13mm galvanized large head felt nails, this is the most ideal case. This is because the wide head connects the two layers and makes a seam that won't leak. In areas with wind, use roofing cement to seal it up for extra protection.
The Depth Stop
Hammer until the head is level with the felt surface. If you hammer too hard, you rip the felt and let water in. It gets stuck on things if it's too high. It seems easy, but many people who do it themselves overdrive these nails. Our hardened shank lets you stop cleanly without bending the nail as you fix it.
Real Customer Feedback (Global Market Insights)
We analyzed data from our top markets: Germany (DIY stronghold), Australia (harsh sun), and the UK (constant rain). Here is what actual site managers are saying
– Klaus, Site Foreman, Berlin, Germany
"Finally, a nail that doesn't bend after the third hit."
★★★★★
"We are very strict about processing quality in Germany." The Sinsun 15mm wool tacks are all the same. You don't have time to pull out bent nails when you're on your knees on a roof. Every time, they drive straight. The head kept the bitumen feeling tight against the ply. "I've already ordered a second pallet."
– Renovations in Brisbane, Queensland, Australia
"Made it through the cyclone season." "Impressed."
★★★★★
"We used the 20mm shed roof felt nails to re-inspire the large carport." Our biggest worry is UV damage and wind damage during storms. No rust stains in the gutters after six months, and not one nail has come loose. The big head works. "I'll stick with Sony just for the price."
– Trade Direct, Manchester, UK
"Test in UK weather. "Passed with flying colors."
★★★★★
"As a supplier, we check everything. We let some of these roof felt tacks sit outside in the rain for three months. No rust. That's what makes factory-direct goods better than cheap imports. Our builders love that they come in sealed boxes, so there is no rust in the van.
Do roofing shingles nails have a zinc coating?
They should be. The finish on Sinsun nails is hot-dipped galvanized. If you see "electro-galvanized," don't use them outside; they'll rust in a season. Our coating is thick enough to last even when you're outside all the time.
How thick should felt nails be for a shed roof?
A: The 15mm wood nail is the right size for standard 11mm to 12mm plywood or OSB. It is deep enough to hold up against the wind, but not so deep that it passes through the roof boards' bottom. If you want two felt layers on top of each other, use 20mm.
Do I need large felt nails for mineral feel?
Yes. Mineral wool (cap sheet) is heavy and rough. Over time, small head sizes will tear through mineral surface. You need large head tack nails with a head diameter of 10 mm or more to hold the material in place without tearing it.
Can I use these to nail padded pads to the floor?
Yes, of course. Choose 10mm or 12mm lengths. Make sure you nail to a wooden subfloor. Standard smooth-shank underlayment nails squeak over time. The ring shank stops this from happening.
What's the difference between nails for roofing shingles and nails for shed sheets?
Shed shingles nails are shorter for small buildings, while roofing shingles nails have wider heads to prevent roofing material from tearing.
Can you use Sinsun textured nails outdoors?
Yes, all of our felt nails are galvanized or coated to keep them from rusting and getting wet outside.
Can felt nails be ordered in a custom size?
Yes, we offer custom length, diameter, and head type for bulk orders as a factory.
How long do Sinsun synthetic nails last outside?
Galvanized metal nails last 8 to 10 years outdoors, depending on the weather.
Do you sell padded pads with nails?
Yes, we have padded pads with nails in different sizes to protect surfaces.
