Tree trimming that protects your roof — not just your yard.
An overhanging limb is not a curb-appeal problem. It is one of the reason moss keeps coming back after we clean it off. JNR's crew clears back what is actually feeding your roof's moss problem.
Shade, debris, and moisture are the things moss needs most.
An overhanging limb does three things to your roof.
It drops needles, leaves, and seed pods onto the shingles — the organic matter moss spores need to root in. It blocks the sun and wind that would otherwise dry the roof out between rains, so the surface underneath stays damp far longer than it should in a Portland winter. And it gives squirrels and other critters a bridge straight onto the roof, where they can do their own damage to shingles and vents.
Cut the limbs back, and you have taken away the shade and the debris before we ever treat the roof. It is the difference between fighting moss once and fighting it every year. Tree trimming as part of good roof and building maintenance also gives us access for working on your roof. We trim the tree branches away from the building in a way that we think you will appreciate. Every branch is cut with love.
This is what a tree canopy does to a roofline.
Two real Portland roofs, both shaded by mature trees. Neither has been cleaned yet — this is the buildup a canopy leaves behind before moss even takes hold.
What buildup looks like before cleaning
The cause: needles and leaf litter collect fastest along the roof edge closest to the tree line — exactly where moss gets its start.
The effect: the shaded side of this roof stays damp long after the open side has dried — the canopy alone is enough to speed moss along.
Roof clearance is where it starts — not where it ends.
Here is exactly what our tree work covers.
Roof-Line & Gutter Clearance
Standard cutback is at least 5 to 10 feet from the roofline and gutters — enough to open the roof up to sun and airflow. Want more clearance than that? Let us know.
What is included
We can trim trees away from the roof and building and leave the tree debris in a neat pile. We are not setup for landscaping or taking debris with us. If we can use your yard debris can, that would be ideal. However, if you want us to take the debris with us, there will be an extra cost associated.
Full Tree & Yard Service
We have a great trade partner for this if needed. Our tree trimming includes what is needed for roof health, access and to help keep moss and critters off.

Clear the branches, treat the roof — while the crew is already up there.
Trimming alone will not treat moss that is already established.
It stops feeding the problem going forward, but it does not touch what is already growing in the shingles. That's why tree work makes the most sense scheduled alongside a roof cleaning: we clear back what's shading and littering the roof, then clean and treat what has already taken hold — in one visit.
Ask about combining tree trimming with your roof cleaning or maintenance plan visit when you request your estimate. We can build it into one job.
