That changes the job pretty quickly. Surface roots can usually be ground, but they spread the work out, add time, and often matter more to price than homeowners expect.
Most homeowners think about stump grinding as a circular job centered on the stump. Surface roots change that. Instead of one concentrated grinding area, the machine has to follow thick roots outward across the yard in multiple directions.
That matters because the roots are often the real problem. They catch mower wheels, create trip points, interfere with regrading, and push up through thin lawn areas. If those roots stay, grinding the stump alone may not solve what is bothering you.
It also matters for price. A 16-inch stump with three large exposed roots can take longer than a clean 24-inch stump. The stump diameter tells only part of the story. The real scope is the stump plus the length and thickness of the root runs you want addressed.
If roots are raised enough to catch feet or mower decks, they are strong candidates for grinding. These are the roots most likely to affect daily use of the yard.
If you are regrading soil, adding sod, building a bed edge, or preparing for a fence or patio, roots in the work zone usually need to go. Project intent matters more than whether the root is visible from the street.
The first few feet around the stump are usually the most important. That area is where mowing and landscaping problems are most concentrated, and it is often the most cost-effective portion to include.
Not every visible root needs to be touched. Some shallow roots flatten out naturally once the stump is gone and the tree stops feeding the system. Others sit far enough out in the yard that they are more cosmetic than functional.
Grinding every exposed root can turn into a much bigger lawn-disturbance job than most people expect. If the roots are not affecting mowing, drainage, landscaping, or a future project, you may be better off leaving them alone and letting them rot out over time.
This is especially true with roots heading toward mature adjacent trees. Root systems often overlap. A provider should evaluate whether the root you are targeting clearly belongs to the removed tree or is intertwined with another tree you want to keep.
You do not need to map every root in the yard. For quoting purposes, divide them into three buckets:
The first two buckets are usually worth discussing. The third one often is not. That keeps the quote tied to the real problem instead of turning into an open-ended "grind everything" job.
Cottonwood, silver maple, and older poplar are the usual suspects in Spokane and the Valley. These species throw broad, shallow roots that can travel well beyond the canopy drip line and push close to the soil surface.
Black locust can also produce aggressive roots, though its main issue is often hardness rather than spread. Grinding locust roots takes more time because the wood is dense and fibrous. What looks like a moderate root job can turn into a slower one purely because of species.
If you know the tree type, include it when requesting a quote. It materially improves time and cost estimates. This is one reason our guide on how long stump grinding takes emphasizes wood type rather than diameter alone.
Surface-root grinding usually disturbs a wider strip of turf than stump-only work. The grinder has to follow each root path, which creates a series of shallow, linear cuts across the lawn rather than one contained hole.
That does not mean the yard is wrecked. It does mean you should expect more finish work afterward. If you want the lawn to look clean again, plan on adding topsoil and reseeding those root runs once the grinding is done.
If you are already planning lawn repair, it can be efficient to pair this with your post-grinding restoration. Our guide on planting grass after stump grinding covers how to deal with the chip-filled area and reseed successfully.
The best quote request for a surface-root job includes more than stump diameter. Take one photo standing back far enough to show the full root spread, then one closer photo of the thickest roots.
Also explain what you actually want done. "Grind the stump and the two roots lifting the lawn toward the sidewalk" is a much better scope description than "remove all roots." That kind of detail leads to tighter pricing and fewer surprises.
If roots are also tight to a fence, wall, or hardscape, say that too. Limited access changes how the work is done. For that scenario, see our guide on stump grinding near a fence.
The stump is often not the expensive part. It is the extra width of the work area. Once the grinder starts chasing roots three, six, or eight feet away from the stump, the job stops behaving like a simple round hole in the yard.
The other surprise is cleanup. A stump-only job leaves one chip pile. Root grinding leaves a wider disturbed area that usually needs topsoil and seed in several runs. If you are planning lawn repair anyway, that is not a big problem. If you expected the yard to look untouched afterward, it is better to set expectations now.
We serve Spokane and surrounding communities. Describe which roots are causing problems so we can quote the actual scope rather than just the stump diameter.
Not automatically. Many quotes assume the main stump only unless the roots are clearly visible and discussed upfront. If you want roots handled too, point them out in photos or describe them specifically when you request the estimate.
That depends on access, root thickness, and whether the roots are actually causing a problem. Many jobs focus on the first few feet around the stump or on specific raised roots rather than every root on the property.
It can leave shallow disturbed runs where the roots were ground. These areas are usually backfilled and can be repaired with topsoil and seed, but they are more noticeable than stump-only cleanup.
Usually yes. They increase grinding time and widen the work area. A modest stump with large exposed roots can cost more than a larger stump with a contained root flare.
Yes, after the stump is ground and the tree is no longer alive, the remaining root system decays over time. The question is not whether it will decay, but whether the roots are causing enough present-day problems that you want to pay to address them now.
Call or submit the form. We serve Spokane and surrounding areas and can quote the roots separately or as part of the full job.
