Our mushroom-head roofing nails feature a wider head than the standard (up to 0.79 inches). We are well the consequences of using cheaper alternatives—heads that pop out of soft asphalt, or rubber washers that shatter after just two summers. We select Q195 and Q235 carbon steel to achieve the right balance of hardness and flexibility. This is hard enough to penetrate plywood without bending, yet flexible enough to withstand wind loads without snapping. For coastal or highly corrosive environments, we use the same molds to produce 304 and 316 stainless steel products. As a result, you can expect consistent geometry regardless of the material you choose.

Our manufacturing process is unique in that we do not source from traders, but instead independently determine coating thickness and thread pitch, as well as test the strength of the connection between nuts and bolts. This means that when you purchase Sinsun products, you pay the exact price a contractor would pay when sourcing directly from the steel mill. There are no middlemen, and no product specifications compromised to meet retail prices.

Material Options
Q195 / Q235 carbon steel, SS304, SS316.
Shank Type
Smooth or twist ring—twist provides up to 40% higher withdrawal resistance per industry pull tests.
Point
Diamond point standard; blunt point available for specific roofing membranes.
Head-to-Shank Junction
Reinforced fillet to prevent head separation under impact.
Coating
Hot-dipped galvanized (40–60g/m², salt spray tested to 96 hours) or electro-galvanized for indoor applications.
Washer Materials
EPDM rubber (UV and heat resistant to 120°C) or nylon (low friction, good for metal-to-wood applications)
Key Applications (Where to Use Them)
Putting on scalap Yellow
This is where the head of the umbrella gets its name. It is possible to sneeze and have a regular flat-head nail go right through the three-tab or architectural shingles you are nailing down.The umbrella head spreads the force over the shingle's surface, which cuts down on blow-throughs. For this job, I always suggest a twist shaft. Roof decking expands and contracts with humidity, and a smooth shank will slowly back out over ten years. You get a mechanical interlock with a twist shank. Don't overdrive; make sure the head is flush with the shingle surface.
Torch-On Membrane for Flat Roofs
You know how it goes if you've ever done a torch-applied modified bitumen roof: the membrane gets hot, and cheap nails with plastic washers bend and soften. We offer umbrella nails with EPDM rubber washers specifically for this purpose. EPDM can handle the heat from torches without melting, and the rubber compresses to seal the hole where the torch goes in. For one layer of insulation board and membrane, two inches is usually sufficient. Length is crucial here. For two layers, go up to 3 inches or more.
Metal roofing on wood purlins
In Australia and New Zealand, where Colorbond steel is the norm, the market is very big. What is the main mistake I see? Using galvanized carbon steel nails on steel that has been coated with zinc-alume. That would lead to a galvanic corrosion disaster. You need stainless steel umbrella nails (304 or 316) for metal roofing. The twisty shank keeps the nails from coming loose when the wood dries and shrinks. And the umbrella head, along with a nylon washer, makes a weather seal that doesn't hurt the metal's coating. Drive until the washer compresses; if you drive too hard, the seal will break.
Fixing the insulation board
When commercial roofers attach rigid polyiso or XPS insulation to steel decking or wood, they often require longer fasteners. Here, a 6-inch umbrella nail with a 0.79-inch head is normal. The wide head prevents the fastener from sinking into soft insulation, which would create a thermal bridge and lower the R-value. We use these with a sharp diamond point that cuts straight through steel decking. The twist shank keeps the insulation tight on timber decks even after the wood dries out.
Real Customer Feedback (Global Market Insights)
I pulled feedback from our active markets—Australia (metal roofing), Canada (flat roofs), Germany (energy retrofit), and Japan (seismic + precision). Here’s what actual site teams told us:
"We do a lot of IKO torch-on work." People called me back because cheap plastic washers would break and harden after two years. Sinsun EPDM washers stay bendable. I put a box on a roof that gets lots of sun. Three years later, there were no leaks. The hot-dipped galvanized is holding up well in the air near the lake with road salt. "Good product, fair price."
"We put 160mm of insulation on wood decking. You'd bend one out of five cheap 4-inch nails. Even through thick PIR board, Sinsun 6-inch umbrella nails drive straight. The head doesn't rip the face. I don't have time for pointless movement. This is the nail we now use.
FAQ
What is the difference between umbrella heads and standard flat head roofing nails?
A: The umbrella head has a wider, concave shape that spreads the clamping force. Flat heads can punch through soft materials like asphalt shingles or insulation. Umbrella heads also self-seal better when paired with a washer. For any application where water penetration or material tear-out is a risk, go with an umbrella head.
Are umbrella head roofing nails galvanized?
A: They should be for exterior use. We offer hot-dipped galvanized (thicker, longer-lasting) and electro-galvanized (lighter coating, for indoor or short-term exposure). Hot-dipped is the industry standard for roofs—it survives salt spray, freeze-thaw cycles, and UV exposure. If a supplier doesn’t specify the coating type, assume it’s too thin to last.
Do I need rubber washers for umbrella nails?
A: It depends on the roofing material. For metal roofing or torch-on membranes, yes, the washer creates a watertight seal around the nail shank. For asphalt shingles, no washer is typically needed because the shingle’s adhesive strip seals around the head. But if you’re re-roofing over existing felt, washers add an extra layer of protection against capillary wicking.
What gauge umbrella nail for metal roofing?
A: 11 gauge (approx. 3.0mm) is standard for metal roofing over timber. 10 gauge (3.4mm) is used for high-wind zones or heavier gauge metal panels. Don’t go thinner than 11 gauge—metal panels put more stress on fasteners than shingles do, and you need the shank thickness to resist shear loads.
Can I use stainless steel umbrella nails with aluminum flashing?
A: No, that's a galvanic corrosion risk. 304 or 316 stainless steel is close to aluminum on the galvanic scale, but contact can still cause pitting over time. For aluminum flashing, use aluminum nails or isolate them with a non-conductive washer. For most metal roofs (steel or zincalume), stainless steel is the safest choice.
What are umbrella nails used for?
A: Secure metal roofing, shingles, felt, vents, and outdoor construction.
What’s the difference between smooth and twist shank?
A: Smooth drives faster; twist has stronger anti‑pullout grip.
Do you provide umbrella nails with washers?
A: Yes, rubber and plastic washers for waterproof sealing.
Are Sinsun umbrella nails rust‑resistant?
A: Yes, galvanized and stainless steel options for outdoor use.
What sizes are available for umbrella nails?
A: 1‑1/2″ to 3″, gauges 8–14, in stock and custom lengths.
Can I use umbrella nails for metal roofs?
A: Yes, they are widely used in corrugated and metal roofing.
Do you accept custom umbrella nail orders?
A: Yes, custom lengths, shank, head, and coating for bulk.
What packages do you offer?
A: Cartons, gunny bags, pallet packs for global shipping.
Are sealed umbrella nails waterproof?
A: Yes, with integrated washers to seal the nail holes.
Why choose umbrella head over standard nails?
A: Prevents tearing, distributes pressure, improves appearance.
