Roof brackets, also called roof jacks, are steel supports you nail to the roof to hold a plank you can stand and work from on a sloped surface. To use roof brackets, drive 16d common nails through the bracket strap into the rafters or trusses, set the brackets 6 to 8 feet apart, lay a graded 2×10 plank across them, and secure the plank to each bracket. They give you a level footing for shingling, painting, or repair on a pitch too steep to stand on. 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” is the same tool under a different regional name, so the two terms are interchangeable on most job sites. 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, which for most people starts around a 6:12 slope and becomes necessary by 7:12 to 8:12. On roofs of 4:12 or less, many workers move without staging. 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 decision.
Tools and materials you need
Roof bracket setup uses a short, specific kit. The plank grade matters as much as the brackets, because a cracked or ungraded board is the part most likely to fail under load. 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) | Full-shank nails into framing resist pull-out; short roofing nails do not |
| Plank | Scaffold-grade 2×10, 12 to 16 ft | Graded lumber carries the point load without cracking |
| Hammer or framing gun | 22 oz or higher | 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 strap through the top of a shingle course and into the roof framing, then hang the plank once a line of brackets is set. The single 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 or eye a level line across the roof where the plank will sit, and mark bracket spots 6 to 8 feet apart along it.
- Lift the top edge of the shingle at each mark so the bracket strap tucks under the course above.
- Drive two or three 16d common nails through the strap slots, 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, overlap plank ends by 1 to 2 feet directly over a bracket, 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 6 to 8 feet apart horizontally, and position a bracket within about 1 foot of each plank end so the board never cantilevers far past its support. A 12-foot plank on brackets 8 feet apart leaves 2 feet overhanging each side, which is the practical limit. Where two planks meet, lap them over a shared bracket rather than butting them mid-span, so no joint hangs unsupported.
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 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.
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 fall protection for residential roofing work above 6 feet, and a bracket plank does not satisfy that rule on a steep roof. 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.
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 welded to one pitch and level the plank only on a matching slope, while adjustable brackets pivot so one set works across several pitches. Adjustable models cost more and 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 | Roughly 4:12 to 12:12 |
| Typical cost each | $8 to $15 | $15 to $30 |
| Best for | Single job, known pitch | Crews on varied roofs |
| Maintenance | None | Inspect the pivot 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. 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 and roof jack are two names for the same steel support that nails to the roof and holds a plank for working on a slope. The term varies by region and supplier. 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 strap and into a rafter or truss, not short roofing nails into the sheathing. The full-length shank anchored in framing resists the pull-out force of your body weight on the plank. Drive two or three nails per bracket, and place them where the next shingle course will cover the heads so the roof stays watertight.
How far apart should roof brackets be spaced?
Space roof brackets 6 to 8 feet apart along a level line, and keep a bracket within about 1 foot of each plank end. That spacing limits how far the 2×10 plank spans and how far it overhangs, both of which control deflection under load. Where two planks meet, overlap them over a shared bracket instead of butting them in open space.
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 above 6 feet, 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?
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. On slopes of 4:12 or flatter, many workers move without staging. 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. Remove them by tapping up the slope to release the keyhole slots from the nail heads, which frees the bracket without damaging it or the finished shingles.
