"I had a large branch from a tree in my yard resting on my Garage roof. Roper Tree Surgeon and Landscaping arrived at our scheduled time and the crew went right to work. They cut the tree off the roof as well as cut the tree down to the ground so the whole tree is gone. They cleaned my backyard and the roof of all the branches they cut. All the employees were extremely polite and respectful of my property. They did an excellent job. I will definetly use their services again in the future ."

"Robert Duran and his crew from 3-D Tree Services, Inc. were top notch today from the quote/survey to completion! I am amazed how quick, efficient, professional and kind this entire team is to work with! This was a tough job (Old/Invasive Pepper Tree). The crew was in sync with each other, allowing the process to be quick and safe. I’m so happy I found them through Home Advisor and the response to my inquiry was quick. Thank you everyone! Referrals will flow!"

Arborists questions, answered by experts

Tree roots are hearty and complex systems, so they don’t die immediately after the rest of the tree is removed. If you leave the root system in place, it takes anywhere from two to seven years for it to run out of nutrients. It is worth noting, however, that the roots stop growing and expanding after cutting down the rest of the tree.

The best time to trim trees is in late fall through winter when the tree has slowed its growing for the year. Cold weather stops insects and fungal growth from attacking a new tree wound. Summer and fall are considered the worst times to trim trees, but it’s permissible in certain scenarios, such as tree disease, damaged branches, or small, aesthetic cuts.

Most experts recommend removing a tree that has sustained more than 25% loss in the limbs, trunk, or circumference of the bark. Doing an initial trimming of damaged and dangling branches, but then waiting a few days of monitoring to decide how much more you might need to cut can help you better assess the total damage to the tree. However, consulting a tree maintenance pro to make this determination the best course of action before removing a tree.

It can take anywhere from one month to a couple of years for tree roots to grow back in sewer lines. Tree roots can cause extreme havoc on your sewer lines, potentially cracking them and causing untreated wastewater to make its way into the groundwater. Have a landscaping pro remove trees and roots before installing your system, or call a pro to do it retroactively as soon as you can.

Licensing requirements for arborists, also known as tree surgeons, vary by state and municipality. Many areas require a license, which often involves specialized education and experience. Even if not mandated, it's wise to hire a licensed professional as they tend to have more experience. Beyond licensing, look for certifications from organizations like the International Society of Arboriculture (ISA) or the Tree Care Industry Association (TCIA), as this indicates a higher level of expertise. Certified arborists must typically pass a comprehensive exam. Always confirm that the arborist has a business license and is fully insured to protect yourself from liability. Seeking positive recommendations from local homeowners is also a good step in finding a qualified professional.
