Fallen tree roof repair for Portland homes
A fir limb or whole tree on a Portland roof is a framing problem as much as a roofing problem. Rafters, ceiling joists and decking often need rebuilding before any shingles go back on.
Fallen tree roof repair in Portland usually costs $1,640 to $14,860 or more, depending on whether the tree only broke shingles or cracked rafters and decking. The tree has to come off first, ideally with a tree crew and crane, then we inspect the framing, sister or replace broken rafters, rebuild sheathing and reroof to match. Call (503) 917-5484 any hour.
When a tree comes down on a house, the visible hole in the roof is usually the smallest part of the damage. A falling Douglas fir trunk carries enormous weight, and it does not just break shingles. It cracks rafters, snaps ceiling joists, splits the ridge board and can push the top plates of walls out of line. A single large limb can do the same on a smaller scale, punching through decking and leaving cracked framing on either side of the hole.
That is why fallen tree repair is a sequence. First the tree comes off the house safely, usually by a tree service using climbing gear or a crane so the weight is not dragged across the roof. Then we get into the attic and on the roof to see what the framing actually looks like. Only after the structure is sound do we rebuild decking, underlayment, flashing and shingles.
Rushing that order causes problems. Shingling over a cracked rafter leaves a sag that holds water and may fail under the next snow load. Pulling a tree off the house with a truck can tear more roof off than the fall did. We work alongside the tree crew from the start so each step happens in the right order and the house is covered between them.
How to tell how badly a tree damaged your roof
Some damage is obvious and some only shows up once the tree is off; these signs help gauge the scale.
Branches poking into the attic
If limbs came through the decking, the sheathing is broken and rafters nearby are likely cracked. Keep people out of rooms below until the roof and ceiling are checked.
Ceiling cracks or sagging drywall
New cracks in ceilings or walls below the impact point, or a ceiling dipping downward, suggest the framing took load and may have shifted. That needs a structural look, not just roofing.
Roofline dips after removal
Once the tree is off, sight along the ridge and eaves. A dip or wave means rafters are bent or broken and must be repaired before new roofing goes on.
Doors that stick suddenly
Interior doors that start binding after a tree strike can mean walls were pushed out of square. That points to damage beyond the roof surface that needs checking.
Gutters and fascia torn away
Limbs often strip gutters and crush fascia boards on the way down. The roof edge has to be rebuilt along with the gutter before water management is restored.
Shingles scraped but intact
Smaller branches may only scrape granules or crack a few shingles. That damage is minor, but it still needs repair, and the decking under the strike should be checked.
How we repair a roof after a tree comes down on it
Make the house safe and dry
On the first call, we check for hazards like downed lines and cracked framing, keep people out of unsafe rooms and cover open areas around the tree as best we can until it can be removed.
Coordinate removal with the tree crew
We work alongside the tree service you choose, or with your insurer's, so the tree is lifted or cut off in sections without dragging across the roof. A crane is often the safest way for big firs.
Inspect rafters, joists and ridge
With the tree off, we go into the attic to check every rafter, ceiling joist, the ridge board and wall plates in the impact zone. Cracked or bent members are marked and photographed.
Rebuild the framing
Damaged rafters are sistered with new lumber bolted alongside or replaced outright. Broken ridge boards and collar ties are rebuilt. Where the damage is extensive, an engineer's input guides the repair.
Replace decking and reroof
New plywood sheathing goes on over the restored framing, then synthetic underlayment, ice and water shield where needed, flashing and shingles matched to the rest of the roof.
Restore the roof edge and gutters
Crushed fascia and soffit are rebuilt and gutters rehung or replaced. We finish with a check of the whole roof, since a big fall can shake loose shingles and flashing well away from the impact.
Why Portland sees so many trees on roofs
Portland is a city of very large trees close to houses. Douglas firs over 100 feet tall stand in backyards across Eastmoreland, Multnomah Village and the Southwest Hills, and bigleaf maples spread over roofs in Laurelhurst and Mount Tabor. Saturated soil from months of rain loosens root plates, so when a winter windstorm arrives, whole trees can tip rather than just drop limbs.
The January 2024 ice storm made it painfully clear. Ice loading snapped limbs and split trunks across the metro, and for days tree crews and roofers worked the same streets in Gresham, Happy Valley and east Portland. On steep West Hills lots, crane access is limited and some trees must be cut down in pieces from the roof, which takes careful planning between the tree climbers and our roofers.
Materials for fallen tree roof repair come from manufacturers such as Malarkey, GAF, Owens Corning, CertainTeed, Carlisle and Velux, chosen for the job rather than the logo.
Repair scope based on how far the damage reaches
Tree damage repairs fall into roughly four levels, depending on what the fall broke.
Surface shingle and flashing repair
When smaller limbs only scraped or cracked shingles and bent flashing, we replace the damaged roofing and check the decking underneath. This is the lightest kind of tree damage repair.
Decking replacement
A limb that punched through the sheathing but left rafters sound needs the broken decking cut out and replaced, followed by underlayment and new shingles over the patched area.
Rafter sistering and decking
Cracked rafters are reinforced by fastening new full-length lumber alongside them. This keeps the original framing in place and restores strength before new sheathing and roofing are installed.
Major structural rebuild
When a large tree breaks multiple rafters, the ridge or wall plates, the roof section is rebuilt from the framing up, often with engineering guidance and a building permit before reroofing.
What fallen tree roof repair costs in Portland in 2026

No two tree strikes are alike, so read these as general ranges, not a quote. Tree removal is billed by the tree service. You get our real price after an on-roof and attic look and a written estimate.
What moves the price:
- Size and weight of the tree or limb
- Number of rafters or joists broken
- Crane or climber removal access
- Engineering or permit needs
- Matching existing shingles
Why the order of work matters on tree damage
We start with the framing
New shingles over cracked rafters will sag and leak. Checking and repairing the structure first is what makes the finished roof sit straight and stay dry.
We work with the tree crew
Coordinating with the tree service on how the tree comes off prevents extra damage and keeps the house covered between removal and repair.
Thorough notes for your claim
Photos of the tree on the roof, the broken framing and each repair step give your insurer a clear record of the damage and the work done.
Whole roof checked afterward
A heavy impact can shake loose shingles, flashing and boots far from the strike. We look over the entire roof before calling the job finished.
Fallen Tree Roof Repair questions from Portland homeowners
Who removes a tree that fell on my Portland roof?
A tree service removes the tree, and we repair the roof. We coordinate with whichever tree crew you or your insurer choose so the tree is lifted or cut in sections without dragging across the house. For large firs, a crane is often safest and protects the remaining roof.
Can a roof be repaired after a tree cracks the rafters?
Yes, in most cases. Cracked rafters are usually sistered with new lumber fastened alongside, which restores strength without removing the original framing. When several rafters or the ridge board are broken, that section is rebuilt. Either way, framing is fixed before any new decking or shingles go on.
How long does fallen tree roof repair take in Portland?
Small limb damage can be repaired in a day. Jobs with broken rafters usually take several days, and a major rebuild with permits can take a few weeks, mostly waiting on removal, engineering or insurance approval. The roof stays tarped or wrapped between steps to keep the house dry.
Does insurance cover a tree falling on a house in Portland?
Homeowner policies commonly cover a tree that falls on a house during a storm, including roof and framing repair and often tree removal from the structure. Policy limits and deductibles vary. We provide photos and a written scope to support your claim, and the coverage decision is your insurer's.
Is it safe to stay in my house after a tree hits the roof?
It depends on the damage. Avoid rooms directly under the impact, watch for cracked ceilings or sagging, and keep clear of any downed power lines. If walls are cracked or doors suddenly stick, leave until the structure is checked. Call (503) 917-5484 and we will help assess it.
