Factory guide to roofing membrane gloves for torch-on bitumen, SBS and APP rolls, hot mastic and wet roof handling, with practical material choices, EN 388 and EN 407 limits, MOQ, AQL, packing and FOB export notes.
Start With the Roof Task, Not One All-Purpose Glove
A bitumen roofing crew normally needs more than one glove on the same job. Carrying 25 to 40 kg SBS or APP rolls, aligning a 100 mm side lap, trimming membrane around outlets, brushing primer and working beside a propane torch are different risks. A 13 gauge sandy nitrile glove gives good dry and damp grip on mineral-faced membrane, but it is not a safe contact-heat glove for holding freshly torched asphalt. A split cowhide palm glove handles abrasion and brief heat better, but it is clumsy when the worker is trying to pinch a lap edge or cut a neat corner with a hook blade. For sourcing roofing membrane gloves, start with the station: roll handling, cutting and detailing, torch-adjacent work, wet roof handling, or hot mastic contact. Then specify the risk, not just the trade name. EN 388:2016 plus A1:2018 is the normal base standard for mechanical risks such as abrasion, blade cut, tear, puncture and ISO 13997 TDM cut. EN 407:2020 only matters when the glove has been tested for heat behaviours such as limited flame spread, contact heat or convective heat. Many coated knit gloves used on roofs have no EN 407 claim because they are handling gloves, not heat PPE. GloveMark will not describe a nitrile dipped glove as torch-safe unless the exact construction has test data to support it.
Where Knitted Dipped Gloves Work Well
GloveMark makes knitted and dipped work gloves in Yiwu for handling and general roofing use. Common roofing builds are 13 gauge polyester or nylon liners with black sandy nitrile palm coating, 15 gauge nylon with flat nitrile for lighter inspection and detailing, and 13 gauge HPPE blend liners where metal flashing, knife slips or sharp deck edges add cut risk. For membrane crews, sandy nitrile is usually a better first sample than smooth PU because it bites better on dusty SBS sheets, damp underlay, mineral granules and foil-faced insulation boards. Latex can feel very grippy in dry conditions, but it is not our default for bitumen work because oils, ageing and some residues can soften or reduce its service life. A practical private-label SKU is 13 gauge polyester, black liner, black sandy nitrile palm, elastic knit wrist, sizes 8 to 11, 12 pairs per inner polybag and 120 pairs per export carton. Carton weight depends on size and coating thickness, but many dipped roofing styles sit around 10 to 15 kg gross per carton. If cut protection is required, we can sample HPPE, glass fibre or steel-fibre blends and arrange EN 388 testing, including the TDM letter rating from A to F when needed. The buyer should expect a price step: a cut liner costs more than standard polyester, feels firmer, and may not breathe as well in hot roof weather. For simple roll carrying and sweeping debris, a polyester or nylon liner is often the more honest cost choice.
Where Leather and Sewn Gloves Still Beat Dipping
Torch work is the area where catalogue claims often become dangerous. Nitrile, PU and latex coatings are polymers. Near flame-heated metal, molten bitumen or hot mastic, they can glaze, harden, smoke or fail. For workers guiding a torch-on seam, handling warm flashing or working near kettle-applied material, a sewn glove with split cowhide palm, cotton lining and a longer cuff is usually a more realistic choice than a dipped glove. GloveMark can produce sewn leather and textile gloves with split cowhide palms, canvas backs, keystone or wing thumbs, cotton jersey lining and safety cuffs around 70 to 100 mm. We can add thumb-crotch reinforcement, a frequent wear point when pulling rolls or gripping membrane edges. We do not claim leather is automatically EN 407 certified. If a distributor needs EN 407:2020 contact heat level 1 or level 2, the finished glove has to be tested as the exact stack: leather thickness, lining, thread, cuff and reinforcement. Changing from polyester thread to aramid thread can matter near heat zones. Changing leather grade or lining weight can also change results. For many roofing distributors, the better programme is two SKUs: one 13 gauge sandy nitrile glove for handling, cutting and wet grip, plus one split leather heat-adjacent glove for torch crews. Trying to make one low-cost glove cover grip, cut, water and heat usually creates a poor glove and a weak liability position.
Water, Tar and Solvent Reality on Roofing Sites
Roofing gloves do not work in clean assembly conditions. They see rainwater, asphalt dust, mineral granules, plywood splinters, aluminium trim, primer, tar staining and sometimes solvent-based cleaners. A fully coated nitrile glove gives more splash coverage, but it traps sweat during a 6 to 8 hour shift, especially on summer roofs. A palm-coated sandy nitrile glove breathes through the back of the hand and is normally better for long roll-handling work. A three-quarter nitrile dip is a middle option when workers kneel in wet areas, handle damp insulation boards or touch wet membrane edges. Do not treat a standard roofing grip glove as chemical PPE. EN ISO 374-1:2016 and EN ISO 374-5:2016 are the relevant chemical and microorganism glove standards, but most knitted dipped roofing gloves are not built or certified for solvent breakthrough. If the crew uses bitumen primer, PU adhesive, acetone, white spirit or proprietary cleaners, the buyer should provide the SDS and target breakthrough time before asking for a chemical claim. GloveMark can develop nitrile-coated handling gloves, but we do not sell them as certified chemical gloves without lab testing against named chemicals. For appearance, black liners and black coatings reduce complaints. White PU or light grey nylon may photograph clean in a catalogue, but it can look unsellable after one shift with bitumen dust.
OEM Details That Change Wear Life
Small construction choices change real roof wear more than broad phrases like heavy duty. A 13 gauge liner gives a stronger outdoor handling feel and is common for membrane work. A 15 gauge liner improves fingertip control for trimming laps, but it has less bulk against mineral grit. A 10 gauge acrylic or cotton blend can feel warmer, but it is thicker and less precise. Elastic knit wrists keep granules and deck dust out; safety cuffs are easier to shake off quickly if contaminated with hot mastic. Palm double-dipping, thumb-crotch patches and a raised sandy nitrile finish can extend wear, but every change affects price, sample timing and carton weight. For OEM branding, GloveMark can apply heat-transfer logos on the back of hand, woven size labels, printed polybags, header cards and export carton marks. Heat transfer works best on smoother nylon or polyester backs; it is less reliable on hairy acrylic, rough terry or uneven leather. For dipped gloves, black and grey coating colours are the most stable and easiest to repeat. Pantone-matched liners are possible, but dyed yarn normally needs higher MOQ than stock black, grey or blue yarn. A realistic sample route is 7 to 10 days for a stock-yarn dipped glove, 10 to 15 days with reinforcement or special logo work, and 2 to 4 weeks if third-party EN 388 or EN 407 pre-testing is included.
MOQ, Testing and Buying Plan
For straightforward knitted dipped roofing membrane gloves, practical MOQ is usually 3,000 to 5,000 pairs per colour with a sensible size mix such as 8, 9, 10 and 11. Very small size splits can raise cost because dipping lines and packing teams lose efficiency. Sewn leather roofing gloves follow a different logic: leather yield, cutting dies, lining stock and cuff material matter more than yarn. For standard split cowhide and canvas constructions, 1,200 to 3,000 pairs per style is a realistic first-order range. Lead time after sample approval is commonly 4 to 7 weeks for dipped gloves and 5 to 8 weeks for sewn leather gloves, excluding sea freight, customs and local delivery. Add buffer before Chinese New Year. Inspection should cover more than carton count. For roofing gloves we check size ratio, liner weight, coating coverage, palm thickness consistency, cuff length, seam strength on sewn styles, thumb reinforcement position, logo placement, barcode readability and export carton marks. AQL 2.5 for major defects and AQL 4.0 for minor defects is a common B2B starting point, but heat and chemical claims must be controlled by approved samples and laboratory reports, not by final inspection alone. Export terms can be FOB Ningbo or FOB Shanghai for consolidated PPE shipments. EXW Yiwu is possible, but buyers without their own China forwarder usually find FOB cleaner because export declaration, local transport and carton handover are handled before the goods reach the vessel. For packing plans, 120 pairs per carton is common for dipped gloves; leather gloves may be 60 or 72 pairs per carton because cuffs and palms create more volume.
