Roofing brackets, also called roof jacks or roof plank brackets, are steel supports you nail through the shingles into the rafters to hold a level plank you can stand and work from on a sloped roof. To use them, drive 16d nails through every slot in the bracket’s nailing plate into a rafter or truss, keep brackets no more than 8 feet apart, lay a 2×10 plank across them, and nail the plank to each bracket arm. They give you level footing for shingling, painting, or repair on any roof steeper than 4:12, the slope at which OSHA 29 CFR 1926.500 classifies a roof as steep. They are work staging, not a fall-arrest system, so you still tie off.
What are roof brackets, and are they the same as roof jacks?
A roof bracket is an L-shaped or triangular steel arm that nails to the roof deck and framing to carry a horizontal plank. “Roof jack” and “roof plank bracket” are the same tool under different regional names, and OSHA’s scaffold standard covers the setup as a roof bracket scaffold under 29 CFR 1926.452(h), which requires brackets built to fit the roof pitch, giving a level platform, and anchored with nails. Do not confuse either with a plumbing roof jack, which is a pipe flashing, or with pump jacks, which climb a pole. The bracket holds staging; the plank is the platform.
When do you need roof brackets?
You need roof brackets once the pitch is steep enough that you cannot stand or kneel without sliding. OSHA 1926.500 draws the line at 4:12: anything steeper is a steep roof, anything at or below it is a low-slope roof. For most people footing gets unreliable around 6:12, and staging becomes necessary by 7:12 to 8:12. Above 8:12, brackets plus a personal fall arrest system are standard because a slip gives you no chance to self-arrest. Pitch, not roof height alone, drives the bracket decision; height drives the fall protection decision, which starts at 6 feet under 1926.501(b)(13).
Which roofing bracket fits your roof? Decision table
OSHA 1926.452(h)(1) requires the bracket to fit the pitch and hold the platform level, so match the bracket angle to the roof before you buy. Use this table as the first cut, then follow the maker’s sheet for the exact model.
| If your situation is | Use | Rule or source |
|---|---|---|
| Roof at 4:12 or flatter | No brackets for footing; low brackets only as a material stop or slide guard | OSHA 1926.500 low-slope definition; Qualcraft sells its 2502/2505 only as slide guard or material support on low slopes (Western Safety listing) |
| Roof above 4:12 and up to 12:12 | Fixed 45 degree bracket, such as Qualcraft 2501 | Qualcraft rates the 2501 for 12/12 fixed pitch; IKO notes 45 degree brackets are typically listed for roofs up to 12:12 |
| Roof from 10:12 to 21:12, or several pitches on one job | Adjustable bracket, such as Werner ARB10-10 | Werner sets the ARB10-10 at 40, 50 and 60 degrees for 10/12, 14/12 and 21/12 roofs |
| Roof at 18:12 | Fixed steep bracket, such as Qualcraft 2503 | Qualcraft rates the 2503 for 18/12 fixed pitch |
| You want a 2×12 plank instead of a 2×10 | Heavy duty bracket that seats a 12 inch plank, such as Lynn Ladder HDRB | Lynn Ladder lists the HDRB as supporting a 2 x 12 plank |
| Brackets would land more than 8 ft apart | Add a bracket | Qualcraft 2501 maximum spacing 8 ft; OSHA Appendix A to Subpart L allows an 8 ft span for a nominal 2×10 at 25 lb per sq ft |
| Work surface 6 ft or more above a lower level | Brackets plus harness, rope grab and anchor | OSHA 1926.501(b)(13) residential construction rule |
Roofing bracket specs by model
Published capacity ratings are written per length of staging, not per bracket. Both Qualcraft and Werner rate their brackets for one worker plus 40 lb of material per 8 feet of plank, which is why 8 feet is the spacing ceiling on both sheets.
| Model | Type and build | Pitch or angle | Rated load and spacing | Price seen | Source |
|---|---|---|---|---|---|
| Qualcraft (Guardian) 2501 | Fixed, 11 gauge steel, riveted, 10 in arm | 45 degrees, 12/12 roofs | 1 worker + 40 lb per 8 ft; max 8 ft between brackets | $13.50 to $14.10 each (Oct 2026) | Western Safety product listing |
| Qualcraft 2503 | Fixed | 18/12 roofs | Per maker sheet | Not listed | Western Safety product listing |
| Guardian 2500 | Adjustable steel | Per maker sheet | Per maker sheet | $13.40 (Oct 2026) | Western Safety product listing |
| Werner ARB10-10 | Adjustable, powder-coated steel, 10 in long | 40, 50, 60 degrees for 10/12, 14/12, 21/12 | 1 worker per 8 ft of walk platform + 40 lb | Not listed by Werner | Werner ARB10-10 product page |
| Lynn Ladder HDRB | Adjustable, galvanized steel, Surelock locking, 7 lb | Adjustable to various pitches | Seats a 2 x 12 plank | $69.00 each (Oct 2026) | Lynn Ladder product page |
Tools and materials you need
Roof bracket setup uses a short, specific kit. The plank grade matters as much as the brackets, because OSHA’s span table in Appendix A to Subpart L assumes graded 2×10 lumber: a nominal-thickness plank may span 8 ft at a 25 lb per sq ft load and only 6 ft at 50 lb per sq ft. Buy scaffold-grade or select structural lumber, not a random 2×10 off the rack.
| Item | Spec | Why it matters |
|---|---|---|
| Roof brackets | Fixed or adjustable steel, 4 to 6 units | Adjustable arms level the plank across changing pitch |
| Nails | 16d common (not roofing nails); some makers call for 20d | Full-shank nails into framing resist pull-out; short roofing nails do not |
| Plank | Scaffold-grade 2×10, 10 to 16 ft | Graded lumber carries the point load without cracking |
| Hammer or framing gun | Framing hammer or framing nailer | Seats 16d nails to full depth in one pass |
| Scrap shingle | One per bracket | Slipped behind the bracket, it protects finished shingles |
| Fall protection | Harness, rope grab, anchor | OSHA fall protection is required above 6 ft; brackets are not it |
How to install roof brackets step by step
Install each bracket by nailing its plate through the top of a shingle course and into the roof framing, then hang the plank once a line of brackets is set. Werner’s instruction for the ARB10-10 is 16-penny nails through all slots on the mounting plate. The rule that keeps the roof watertight is to nail where the next shingle course will cover the nail heads, exactly where you would drive shingle nails. Work from the bottom up.
- Snap a level chalk line across the roof where the plank will sit, and mark bracket spots no more than 8 feet apart along it, each landing on a rafter or truss (IKO notes rafters may sit 12, 16, 24 or even 36 inches apart on older roofs).
- Lift the top edge of the shingle at each mark so the bracket plate tucks under the course above.
- Drive 16d common nails through every slot in the plate (Werner ARB10-10 instruction), through the sheathing, and into a rafter or truss. Aim for framing, not sheathing alone.
- Slip a scrap shingle between the bracket back and the finished shingle to prevent scuffing.
- Set the two shingle courses above each bracket before you add the plank, or the plank blocks your nailing.
- Lay the 2×10 across the bracket arms so each end extends at least 6 inches past the bracket centerline (OSHA 1926.451(b)(4)), lap plank ends at least 12 inches over a shared bracket (1926.451(b)(7)), and nail through the turned-up arm holes into the plank edge.
How far apart do you space roof brackets and planks?
Space roof brackets no more than 8 feet apart. That is the maximum Qualcraft prints for its 2501, the span Werner rates for one worker plus 40 lb on the ARB10-10, and the maximum span OSHA Appendix A allows for a nominal 2×10 at a 25 lb per sq ft light-duty load. At the ends, OSHA 1926.451(b)(5) caps the overhang past the support at 12 inches for planks 10 feet or shorter and 18 inches for longer planks, unless the cantilever is designed to carry a worker. Where two planks meet, lap them at least 12 inches over a shared bracket rather than butting them mid-span. OSHA’s scaffold rules bind employers, not homeowners, but they are the clearest published benchmark for a DIY setup.
| Plank | Brackets | Spacing | Overhang each end | Within the OSHA and maker limits? | Source |
|---|---|---|---|---|---|
| 10 ft 2×10 | 2 | 8 ft | 12 in | Yes, exactly at the 12 in cap for a 10 ft plank | OSHA 1926.451(b)(5)(i) |
| 12 ft 2×10 | 2 | 8 ft | 24 in | No: 24 in exceeds the 18 in cap for planks over 10 ft | OSHA 1926.451(b)(5)(ii) |
| 12 ft 2×10 | 2 | 9 ft | 18 in | No: 9 ft exceeds the 8 ft span for a nominal 2×10 and the Qualcraft maximum | OSHA Subpart L Appendix A; Qualcraft 2501 |
| 12 ft 2×10 | 3 | 5 ft | 12 in | Yes | OSHA 1926.451(b)(5)(ii); Appendix A |
| 16 ft 2×10 | 3 | 7 ft | 12 in | Yes | OSHA 1926.451(b)(5)(ii); Appendix A |
How to remove roof brackets without damaging shingles
Remove roof brackets by tapping each one sharply up the slope with a hammer, which slides the keyhole slots off the 16d nail heads and frees the bracket without pulling the nails. Then drive the exposed nails flush with a hammer and nail set, or pull them and seal the hole with roofing cement under the covering shingle. Because the nails sat under a shingle course, the finished roof stays sealed once the bracket is gone. The slotted plate on the Qualcraft 2501 is sold as designed for removal without damaging the shingles.
Roof brackets are staging, not fall protection
Roof brackets and their planks are a work platform, not a fall-arrest system, and treating them as fall protection is the most dangerous mistake made with this tool. OSHA 29 CFR 1926.501(b)(13) requires guardrails, a safety net or a personal fall arrest system for residential construction work 6 feet or more above a lower level, and a bracket plank is none of those. A slip off or between planks is still a fall. The bracket gives you footing; a harness, rope grab, and rated anchor catch you if that footing fails. IKO’s contractor guide makes the same point: brackets cannot be used in place of other required fall safety equipment.
Roofing remains one of the deadliest trades in the country. The Roofing Brief’s own roofing safety and fatality report documents 104 roofer deaths in the 2024 federal injury data, most from falls on sloped roofs. Staging brackets reduce sliding but do not remove the need to tie off.
Fixed vs adjustable roof brackets
Fixed roof brackets are set to one angle and level the plank only on a matching slope, such as the Qualcraft 2501 for 12/12 or the 2503 for 18/12, while adjustable brackets pivot so one set works across several pitches, such as the Werner ARB10-10 with its 40, 50 and 60 degree settings. Adjustable models have a moving joint to inspect, but they earn their keep for contractors who work varied roofs. Fixed brackets suit a homeowner doing a single job on a known pitch.
| Feature | Fixed bracket | Adjustable bracket |
|---|---|---|
| Pitch range | One set angle (Qualcraft 2501: 12/12; 2503: 18/12) | Several settings (Werner ARB10-10: 10/12, 14/12, 21/12) |
| Price seen, Oct 2026 | $13.50 to $14.10 (Qualcraft 2501, Western Safety) | $13.40 (Guardian 2500, Western Safety) to $69.00 (Lynn Ladder HDRB) |
| Best for | Single job, known pitch | Crews on varied roofs |
| Maintenance | Check welds, rivets and plate slots | Also inspect the pivot and locking pin for wear |
Whichever type you use, inspect brackets before each job, replace any with cracked welds or bent arms, and pair them with the right roofing safety equipment. Worn nailing plates are a replaceable part on some models; Lynn Ladder sells replacement plates for the HDRB as model HDRB-P. For the full ground rules on working at height, see our guides to roof safety and using a roof safety harness. If you are staging a full tear-off, the bracket lines follow the same course sequence described in the residential roof installation process.
Frequently asked questions
Is a roof bracket the same as a roof jack?
Yes. Roof bracket, roofing bracket and roof jack are names for the same steel support that nails to the roof and holds a plank for working on a slope; OSHA calls the setup a roof bracket scaffold under 29 CFR 1926.452(h). Do not confuse either with a plumbing roof jack, which is a vent pipe flashing, or with pump jacks, which are pole-climbing scaffold supports for walls.
What nails do you use for roof brackets?
Use 16d common nails, driven through the bracket plate and into a rafter or truss, not short roofing nails into the sheathing. Werner tells ARB10-10 owners to use 16-penny nails through all slots on the mounting plate, and IKO notes some makers call for 20d. Place them where the next shingle course will cover the heads so the roof stays watertight.
How far apart should roof brackets be spaced?
No more than 8 feet apart along a level line. Qualcraft lists 8 ft as the maximum spacing for its 2501, and OSHA Appendix A to Subpart L allows an 8 ft span for a nominal 2×10 plank at 25 lb per sq ft. Keep each plank end at least 6 inches past a bracket and no more than 12 inches past it on a 10 ft plank, or 18 inches on a longer one.
How far can a plank overhang a roof bracket?
Under OSHA 1926.451(b)(5), no more than 12 inches for a plank 10 feet or shorter and no more than 18 inches for a longer plank, and at least 6 inches past the bracket centerline under 1926.451(b)(4). A 12 ft plank on two brackets 8 ft apart overhangs 24 inches at each end, so add a third bracket.
Do roof brackets count as fall protection?
No. Roof brackets and their planks are work staging, not a fall-arrest system. OSHA 29 CFR 1926.501(b)(13) still requires fall protection for residential roofing at 6 feet or more, so you need a harness, rope grab, and rated anchor in addition to the brackets. The brackets give you level footing; they do not catch you if you slip off the plank.
What roof pitch requires roof brackets?
OSHA defines any roof steeper than 4:12 as a steep roof. Most people need roof brackets once the slope reaches about 6:12, and they become standard by 7:12 to 8:12 where you cannot stand or kneel without sliding. Above 8:12, use brackets together with a personal fall arrest system because a slip leaves no room to self-arrest.
Can you reuse roof brackets?
Yes, roof brackets are reusable across many jobs as long as the steel stays sound. Inspect each one before use and retire any with cracked welds, bent arms, or worn adjustment pivots; Lynn Ladder sells replacement nailing plates for its HDRB as model HDRB-P. Remove them by tapping up the slope to release the keyhole slots from the nail heads.
