Buyers walk a house room by room. They run the water, flip the switches, and open every closet.
Trees are part of the purchase in North Texas. Lots in McKinney, Anna, and Melissa often come with builder planted oaks and Bradford pears that are already 10 to 20 years old. Older lots in Sherman, Greenville, and Farmersville can carry post oaks and pecans older than the house. A 15 minute yard walk before closing tells you which kind of lot you are buying.
The home inspector is not looking at the trees
A general home inspection covers structure, roof, plumbing, and electrical. It is not a tree exam. An inspector might note a branch touching shingles or a dead tree near the fence, but that is where it stops. Nobody checks the root flare, tests a fork for included bark, or sorts a thin canopy into drought stress, hypoxylon, or oak wilt.
That gap matters because tree problems do not stay small. Our tree diagnosis guide works a sick tree in order, from soil and flare up into the canopy. The same order works on a showing. Start at the ground and look up.
A 15 minute yard walk that catches most of it
Start at the base. You should see the trunk widen into a root flare where it meets the ground. A trunk that goes straight into the soil like a pole was planted too deep or has soil and mulch piled over the flare. Our root flare guide shows the five minute check.
Next, look at the trunk. Long vertical cracks, peeling bark sheets, mushrooms or shelf fungus at the base, and black patches on an oak all count as flags.
Then step back and read the canopy. Thin top, dead tips on one side, a lot of small sprouts on the trunk, and big dead limbs over the roof or driveway are the pattern to spot. Our roof clearance guide covers the gap a limb should keep from shingles.
The expensive finds, in plain terms
A large dead or dying tree over the house is the costliest find. Removal near a structure takes a crew, rigging, and time, and stump grinding and replanting come after. Get that tree named in writing before closing, not after the first windstorm.
A pattern across several oaks is the second one. If two or three red oaks on the lot, or on the lots next door, died in a line over the last few years, ask about oak wilt before you fall in love with the remaining oaks. Our oak wilt guide covers the signs and the spread through shared roots. One sick oak is a tree problem. A marching line of dead oaks is a lot problem.
Roots and flatwork are the quiet third. Look for a driveway or sidewalk lifted in a line that points back to a trunk, cracks that line up with a root path, and a patio poured tight against the base. Not every lifted slab means the tree has to go, but the repair belongs in your budget, not in your first month surprises.
What a tree check adds while you can still negotiate
Texas buyers often have an option period in the contract. If yours does, that window is when a tree check pays off. You get a short written list: which trees are sound, which need routine pruning, and which are hazards with a reason stated plainly. Photos help. Sellers respond better to a photo of a split fork over the master bedroom than to a vague line about yard work.
Keep the ask narrow and tied to safety. A dead limb over the roof, a split trunk, a dead tree near the fence line. Routine shaping, leaf cleanup, and the pruning you would have done anyway are buyer costs, and asking for them weakens the real asks. Our risk assessment guide explains how likelihood, target, and consequence combine, which is the same logic a seller can follow.
Also check the paperwork side. Some cities and many HOAs in Collin County have rules on removing large trees, even dead ones. Our guides on removal permits and HOA tree rules cover what to confirm before you promise a timeline to anyone.
After closing: the first 90 days
If the check came back clean, your first job is water, not pruning. Trees on a lot that sat vacant or was watered on a seller schedule often go into a move in summer dry. A deep soak every week or two in a rainless stretch beats daily sprinkler runs. If the trees are new builder plantings, our builder tree guide covers the flare, stake, and mulch fixes that cost little in year one.
Schedule the flagged pruning for winter where you can. Most North Texas trees take structural work best in the dormant season, and oaks carry the February through June no prune rule for oak wilt. Put the hazard items first, the clearance items second, and the shaping last. Then take dated photos of the trees you are watching. A photo record turns a vague worry next spring into a clear comparison.
None of this should scare you off a wooded lot. A sound post oak or live oak is decades of shade you cannot buy at any nursery. The point is to buy it with your eyes open, price the known work into the deal, and start ownership with a plan instead of a surprise.
Common Questions
Should I get the trees checked before buying a house in Texas?
Yes, if the lot has a large tree near the house, a tree that leans, or a lot of deadwood in the canopy. A home inspector looks at the house, not at root flares, weak forks, or oak wilt patterns. A short tree check during your option period, if your contract has one, gives you facts while you can still ask the seller to handle a hazard or adjust the deal.
What tree problems cost the most after closing?
Removal of a large dead or declining oak over the roof is the big one, followed by grinding and replanting. A row of dying red oaks can point to oak wilt, which changes the value of every oak on the lot. Cracked driveways from roots and limbs grinding on shingles cost less, but they still land on you if nobody flagged them before closing.
Can I ask the seller to trim or remove a tree before closing?
You can ask. Sellers are more likely to agree to a clear hazard, like a dead limb over the roof or a split trunk, than to routine pruning. Get the request in writing with photos and a short note on what is wrong. If the seller says no, you still learned the cost before the tree became yours, and you can plan the work for the first month instead of the first storm.
The home inspection mentioned the trees. Is that enough?
Usually not. A general inspector may note a limb on the roof or a dead tree, and that note is worth taking seriously. But inspectors do not diagnose species, disease, or root problems, and they do not price tree work. Treat their note as a flag to get a tree specific look, not as the full answer.
