Tree Roots Lifting Patio in Tampa: Causes, Fixes, Costs

Tampa Landscaping Pros · Hardscaping and landscaping for homes in Tampa, St. Petersburg, Clearwater, Dunedin and Temple Terrace.

Tree roots lift a patio or walkway because the soil around the tree is so compacted that the gravel base under the paving is the best place left for the roots to grow. That is the explanation from Penn State Extension. The same extension warns that cutting roots to lay or repair paving can badly hurt a tree's health, survival and stability. So settle what happens to the tree before anyone relays a paver or breaks out a slab. Until then, a raised edge is the part to watch: if anyone could catch a foot on it, keep people off that stretch while you collect written prices. Our crew comes out and measures, and you get a written price before any work starts.

Why tree roots lift a patio, walkway or sidewalk

Tree roots under pavers: the gravel base becomes the root zone

Penn State Extension says urban trees often lift pavement. The reason it gives is compacted soil, which leaves the roots no better place to go than the gravel base under the slab. The Concrete Masonry and Hardscapes Association says a paver patio or walkway needs at least 4 inches of compacted base, a minimum for ideal conditions. That gravel layer is the one Penn State says the roots take over.

Penn State describes this for paving in general, so it covers a patio of pavers, a walkway cracking over roots and a sidewalk heaved by a tree root alike. Ask each company how its repair deals with the reason the roots went under the paving in the first place.

What Tampa's soil adds

UF/IFAS Extension Hillsborough County says urban development in Tampa and Hillsborough County often leaves compacted, nutrient-poor sandy soil. Many Florida flatwoods soils have a weakly cemented organic hardpan, usually 12 to 40 inches down, and a water table that rises to within 5 to 20 inches of the surface, according to UF/IFAS. That is a statewide description, not a survey of your lot.

Put the Penn State explanation next to the Tampa soil note, and compacted ground is a fair thing to have a crew look for beside your paving.

What you can check before you call

Note which tree sits nearest the raised paving and how far the lift runs, and take photos from low angles along the edge. Then try the push test UF/IFAS gives for soil in general: if you struggle to push a tool more than a few inches into the soil, the root zone is likely compacted, which leads to shallow roots and poor drainage. Try it in the bare soil or lawn beside the paving, not through the paving itself.

If the paving dipped instead of rising, you have a different problem, covered in our guide to patio pavers sinking.

Local rules

Cutting roots, removing the tree and the Tampa rules

Why cutting the root is not a quick fix

Cutting the root that is doing the lifting is the step to ask about first. Penn State Extension's warning is blunt: the cut can badly hurt the tree's health, survival and stability.

Questions to put to every company before a root is cut:

Which roots will the repair cut, and how much of the tree's root system is that?
Who judges whether the tree is still sound afterward?
Can the paving be rebuilt in a way that cuts fewer roots, or none?
Is any tree work priced as its own line on the written price?
Will the roots be cut before the paving comes up or after?
What happens to the price if the tree work turns out bigger than planned?

When the tree itself is the question

If the tree itself is in question, Tampa has rules for it. In Tampa, removing any tree 5 inches or more across at breast height, except invasive species, needs a permit, according to the City of Tampa tree permitting page. Pruning a tree 24 inches or more across at breast height needs a permit first, and smaller trees need no pruning permit. A grand tree is 32 inches or more across, and removing a healthy one may need a Variance Review Board, City Council or other public decision.

Every tree removal in Tampa must be replaced by new tree planting, or paid into the city tree fund if there is no room on site. When trees come out as part of a permitted project, they are marked as removals on the site plan. They are reviewed under the building permit, with no separate tree permit.

Florida law adds one exception. A city may not require a permit, fee or replacement to prune or remove a tree at a home when the owner has written proof from an ISA certified arborist or a Florida licensed landscape architect that the tree is an unacceptable risk. Outside the city limits the office changes. In unincorporated Hillsborough County the application fee for a tree removal permit is $81.65. Homes inside Tampa, Temple Terrace or Plant City apply to their city instead.

Planting the replacement away from the paving

UF/IFAS says to keep roots clear of buildings and walks when you choose where trees go. It also says to give a tree planting site 3 feet of soil depth for storm resilience.

Cost

Repairing lifted paving: options and national price ranges

Pavers: lift, rebuild the base, re-lay

Pavers can be lifted and laid again. What goes under them matters. The Concrete Masonry and Hardscapes Association says weak soil or poor drainage calls for a thicker paver base than the 4-inch minimum. Ask whether your lot's soil and drainage call for more, ask for the base depth as its own line on the written price, and ask what the crew does where it finds roots in the base.

National paver labor runs $50 to $80 an hour, or $4 to $11 per square foot, according to This Old House. Ask how many working days the crew needs and what weather would push the date.

Poured or stamped concrete

A heaved poured slab is its own question for a crew: ask whether it would replace a section or the whole slab. Bob Vila (2023) gives about $4 to $30 per square foot for a poured concrete patio nationally, with finishes at the top end. It puts minor crack repair at as little as $300, which is a crack figure, so ask what the quote includes when a slab has lifted.

Cost table: national ranges, not Tampa prices

Item	National range
New paver patio, installed (This Old House, 2026)	$2,400 to $7,000, about $3,800 on average
Paver patio, per square foot (This Old House)	$8 to $25
Poured concrete patio (Bob Vila, 2023)	about $4 to $30 per square foot
Stamped concrete patio (Bob Vila, 2024)	$2,960 to $7,533, average $5,089
Minor concrete crack repair (Bob Vila, 2023)	as little as $300
Planting a replacement tree, depending on size (Bob Vila, 2023)	$100 to $2,000

The City of Tampa fee schedule lists $214 for a residential driveway, patio slab or deck permit. The state surcharge of 2.5% of the permit value, $4 minimum, is added.

The ranges move with the area lifted, the material and the labor. Ask for tree work as its own line, so you can compare the paving price between companies. Our landscaping cost guide covers the wider job, and the hardscaping service page explains how a paver patio or walkway is built.

Checklist

How to compare Tampa companies for a root-lifted patio

A company that quotes without seeing the yard cannot know what it needs, according to the Better Business Bureau, so get a price after an on-site look. The FTC says a written estimate should list the work, the materials, the completion date and the price. Compare bids for the same work, and ask for an explanation if the estimates differ a lot.

In Florida, a residential contract over $2,500 must carry a lien warning. Unpaid subcontractors or suppliers can claim against your property even if you paid the contractor in full. Ask for a written release of lien.

Florida has no general state landscaping licence, according to UF/IFAS Extension Orange County. According to the City of Tampa, contractors who pull permits there register their licence with the city. They keep a workers' compensation certificate or exemption on file. Ask for the workmanship warranty in writing, with what it covers and for how long.

Tree roots and paving questions

Can I just cut the tree roots that are lifting my patio?

Not safely, according to Penn State Extension, which says the cut can badly hurt the tree. Ask each company which roots it would cut and who judges the tree afterward.

Why are tree roots growing under my pavers?

Compacted soil leaves the gravel base as the best place left to grow, says Penn State Extension. UF/IFAS Extension Hillsborough County adds that urban development in Tampa often leaves compacted sandy soil.

Do I need a permit to remove the tree in Tampa?

In Tampa, removing a tree 5 inches or more across at breast height, except invasive species, needs a permit. Every removal must be replaced by new planting or paid into the city tree fund. State law lifts the permit for a tree an ISA certified arborist or a Florida licensed landscape architect documents as an unacceptable risk. We pull the City permit when the job needs one.

How much does it cost to fix a patio that roots have lifted?

Nationally, a whole new paver patio runs $2,400 to $7,000 (This Old House, 2026) and a new stamped concrete patio $2,960 to $7,533 (Bob Vila, 2024). Ask for a walk-over so the crew can check the base and tell you whether a spot repair will hold. Get the square footage, the material and the base depth in writing.

Do I need to call 811 before the paving comes up?

Florida law requires a call to Sunshine 811 at least 2 full business days before digging, and the locate ticket is good for 30 calendar days.
