A certified arborist assesses a tree's health, structure, and risk — diagnosing decay and disease, judging whether it's a hazard, and writing the Florida HB 1159 documentation that lets a residential hazard tree come down with no city permit. The on-site look is usually free, and the answer is honest: sometimes the fix is a trim, not a removal.
Jacksonville lives under some of the biggest, oldest trees in Florida — sprawling live oaks and tall slash pines that are gorgeous until one is leaning over the roof after a storm. The hard question is always the same: does this tree have to come down, or can it be saved? That's what a certified arborist answers. Rather than defaulting to the chainsaw, an arborist reads the tree — its health, its structure, and what it's standing over — and recommends the least-invasive fix that keeps your family and your house safe.
What a tree risk assessment covers
A proper assessment is more than a glance from the driveway. On a Jacksonville property it looks at:
- Decay and cavities. Soft wood, hollows, fungal conks, and carpenter-ant galleries that hollow out a trunk from the inside.
- Structure and lean. Co-dominant stems with included bark, cracked unions, a fresh lean, or a heaving root plate after wind.
- Root health. Girdling roots, root rot, and soil heave — critical in Jacksonville's loose, sandy soil where shallow-rooted trees topple in saturated ground.
- Disease and pests. Oak wilt, hypoxylon canker, pine bark beetles, and palm diseases that change whether a tree is worth keeping.
- Targets. What the tree would hit if it failed — your roof, a car, a power line, the neighbor's fence — which drives how urgent the risk really is.
The HB 1159 hazard letter
Here's where the assessment pays for itself. Under Florida HB 1159, a tree on residential property can be removed without a city permit when a certified arborist (or Florida-licensed landscape architect) provides written documentation that the tree presents a danger. That letter — the arborist's hazard determination — is what makes an otherwise permit-required removal permit-free, and the crew handles it as part of the job. Commercial, multi-family, and protected zones like wetlands or mangroves still follow their own rules. For the full breakdown, see do I need a permit to remove a tree in Jacksonville?
Arborist reports & letters in Jacksonville
Sometimes what you need isn't a crew — it's a document. 904 Tree Service routes those requests to crews with ISA-certified arborists who produce written reports for the situations where paper decides the outcome:
- Permit-free removal letters (HB 1159 / § 163.045). The written hazard documentation that lets a dangerous tree at a single-family home come down with no city permit — see how the permit rule works.
- Insurance reports. A written assessment of a tree's condition before or after a loss — supporting a claim, documenting that a fallen tree was sound (or wasn't), or backing your position when an insurer asks about the trees near the house. Pairs with our guide to when insurance covers tree removal.
- Real-estate and HOA letters. Condition reports for a sale or purchase, and written assessments that settle disputes with an HOA — or with a neighbor worried about your tree (see the neighbor-liability rule).
The quick on-site risk assessment is folded into a free estimate; a standalone written report is a paid service, quoted by tree count and the depth of documentation required. Referral framing, stated plainly: the reports are produced by the independent certified arborists on the crews we dispatch — our job is getting the right one to your address.
When you should call an arborist
An expert look is worth it any time the stakes are high or the answer isn't obvious (our guide to the signs a tree is dying or dangerous covers what to watch for yourself):
- A tree you're not sure about. Leaning, dropping limbs, or looking sick — before you assume it has to go.
- After a storm. A fresh lean or a cracked union needs judgment on whether it's stable or a hazard.
- Before a removal permit question. To get the HB 1159 documentation in hand.
- For an insurance claim or property sale. A written arborist report carries weight with an adjuster, an HOA, or a buyer.
- To try to save a tree. Cabling, bracing, pruning, or treatment can keep a valuable oak standing for years.

The point of an assessment is an honest recommendation, not an automatic removal. Plenty of trees that look like goners are really a pruning or cabling job, and a healthy tree over the roof usually just needs clearance. When a tree genuinely is a hazard, the same crew handles the removal — with the arborist's documentation already in hand and full cleanup included. Either way, you get a straight answer from someone who reads trees for a living.
