Tree Cabling and Bracing in the Roanoke Valley

Roanoke Tree Removal is a local referral service: we pass your request to an independent, local tree crew. We are not a government office or an arborist, and this page is general information, not legal advice.

What cabling and bracing do

Purdue Extension describes two kinds of support. A cabling system uses flexible, extra-high-strength steel strand cables attached to bolts drilled into the upper crown. It shifts load from a weak branch union to a stronger one and limits how far a branch can move in wind, ice or snow. Bracing uses threaded rods installed through a weak union to give rigid support, usually on trees with codominant or multiple leaders. Crews often combine the two.

Defects it can help

• Codominant stems. Purdue calls two or more competing stems, or a V-shaped crotch, the most common risk of tree failure. Purdue says the weakness comes from too little connecting tissue and from bark trapped between the stems.
• Overextended limbs. Long, heavy limbs with most of their leaves near the tip tend to break where they join the trunk, usually under wind, snow or ice.
• A union that has already split. Purdue says bracing can often repair a split crotch or branch union.

The Virginia Department of Forestry lists warning signs to have checked, including large cavities or decay, a conjoined trunk, cracks in the trunk or major limbs, and a one-sided or leaning tree. Bradford pears are a local example: our Bradford pear guide cites DOF calling them structurally weak.

Steel or dynamic cables

Purdue Extension says dynamic, or soft, systems use synthetic rope attached without drilling into the tree. They can be less damaging and work where hardware can't be installed. Steel cables and rods are bolted through the wood. Either way, the aim is the same: limit movement so supported branches are less likely to fail in storms. Ask which type a crew proposes and why.

When it isn't the answer

Purdue is clear that not every tree is a candidate. Poor health, decayed wood or a species of low value can rule a tree out, and support systems are no guarantee against failure. Done incorrectly, they can create a greater hazard. Its list of questions before paying for support includes whether a new tree would be a better long-term investment, and whether you are ready to have the system inspected and perhaps replaced after 7 to 10 years.

For young trees, Purdue says early corrective pruning is the better fix. For a tree with serious decay, see hazard tree removal and remove or trim?.

Start with an assessment

Purdue says to consult a qualified arborist, such as an ISA Certified Arborist, to decide whether a tree can take a support system, and to set clear objectives first. Pruning is often part of the job and should be done before the hardware goes in. The Virginia Department of Forestry gives similar advice: have trees evaluated before removing them, by an ISA-certified arborist. ISA's Find an Arborist directory lets you check a credential. Our arborist risk assessment page explains what a formal assessment covers.

The standard crews work to

The tree care industry's standard for this work is ANSI A300 Part 3, Supplemental Support Systems. The Tree Care Industry Association says it covers installing and maintaining cabling, bracing and guying, including cabling objectives, types of cabling systems, bracing objectives, and dead-end and through-bracing. The standard itself is sold, not free, so ask the company whether it follows A300 and to put the objectives and hardware in writing.

Inspection and upkeep

Purdue Extension says upkeep is minimal but important:

• Check from the ground every year for loose hardware or anything that needs adjusting.
• About every three years, have an arborist climb the tree for a closer look.
• Be ready to replace the system, which Purdue suggests may come after 7 to 10 years.

The Virginia Department of Forestry suggests pruning by a certified arborist every 3 to 6 years, which is a natural time for that closer look. See tree trimming and pruning.

Safety rules in Virginia

Virginia's tree care safety standard, 16VAC25-73, applies to employers that prune, repair, maintain or remove trees and hire one or more people to do it. Purdue calls cable and brace installation a complicated process for qualified arborists. Trees near power lines bring extra rules about who may work in them. Our Virginia tree service licensing guide covers the safety standard, insurance and credentials to check.

What cabling costs

Angi's national figures, not Roanoke quotes. Angi says some arborists waive the consultation fee if you hire them. The number of cables, the height and access all change the price.
