The Short Answer
Trees damage roofs slowly by rubbing shingles bare, dropping debris that dams valleys and gutters, and shading slopes so moss grows. They damage roofs suddenly when a limb falls in wind or under ice. If a tree hits the house, get everyone out of the affected rooms, stay at least 25 feet from any downed wire, call the utility and 911 if lines are involved, and let an arborist remove the tree before a roofer repairs the roof.
Key Points
- A branch resting on or rubbing the roof wears through shingles long before anyone sees a leak.
- After a tree strike, the order is people, power lines, tree removal, then the roof.
- Never climb onto a roof with a tree on it; the load can shift and the deck may be broken.
- The standard ISO homeowners form pays limited tree removal costs, with dollar caps, when wind or ice fells a tree onto a covered structure.
- Keeping branches trimmed back from the roof also cuts off the main route squirrels and raccoons use to reach it.
How Overhanging Trees Wear a Roof Down
Most tree damage is not dramatic. A branch that grew a few feet over the roof rests on the shingles, and every breeze scrubs it back and forth. Over a few seasons it grinds away the granules, then the asphalt, until the mat is exposed. It often shows up as a bald patch or a line of scuffed shingles directly under a limb.
Shade does damage too. A slope that never gets direct sun stays damp after every rain and holds snow longer in winter. That is where moss takes hold, and moss holds water against the shingles.
Then there is debris. Leaves, seeds and twigs pile up in valleys, behind chimneys and at the upper side of skylights. Wet debris acts like a dam. In spring and fall it pushes water sideways under shingles, and in winter it helps ice build where it should not.
- Bare or scuffed shingles directly under a branch.
- Granules collecting in one downspout more than the others.
- Moss or dark growth on the shaded slope only.
- Valleys or the area behind the chimney packed with leaves.
- Small dents or cracked shingles under a tree that drops nuts or dead wood.
When a Limb or Tree Comes Down on the House
In West Michigan, big limbs usually come down in summer thunderstorms with straight-line winds, in ice storms that coat branches with weight they were never meant to carry, and in heavy, wet snow. Dead or hollow limbs fail first, but a healthy tree can lose a big limb in an ice storm too.
The damage ranges from a scrape and a few broken shingles to a limb that punched through the deck and into the attic or the ceiling below. Even a limb that bounced off can crack rafters or break the deck in a way you cannot see from the ground.
What to Do First When a Tree Hits Your Roof
- Step 1
Get People Out of the Rooms Below
If a limb is through the roof or the ceiling is sagging, move everyone out of those rooms and the rooms around them. Ceilings full of water or debris can fall without warning.
- Step 2
Look for Wires Before Anything Else
Trees that hit houses often take service lines with them. Consumers Energy tells people to stay at least 25 feet from a downed wire and anything it touches, to assume it is energized even if it is not sparking, and to call 911 and the utility.
- Step 3
Shut off Power to Wet Areas
If water is coming into a room with outlets or light fixtures, turn off those circuits at the panel if you can reach it safely and without standing in water.
- Step 4
Take Photos Before Anything Moves
Photograph the tree on the roof, the stump or break point, the inside damage and any wet ceilings. Insurers ask for this, and it is hard to recreate once the tree is gone.
- Step 5
Call a Tree Service First, Then a Roofer
The tree has to come off before the roof can be repaired. A roofer can often protect the open area the same day once the weight is off, but nobody should be working under a loaded limb.
- Step 6
Call Your Insurance Agent
Report it early. Policies expect you to take reasonable steps to protect the house from further damage, such as a tarp, and to keep the receipts.
Do not climb onto the roof to look. A tree on a roof is a moving load, the deck under it may be broken, and storm-wet shingles are slick.
Arborist, Utility, Roofer: Who Handles Which Part
A tree strike usually involves several trades, and doing them in the right order saves money and keeps people safe.
Electric utility
Wires down or in the tree
Anything touching or near a power line belongs to the utility first. Do not let a tree crew or a roofer start until lines are confirmed safe.
Tree service or arborist
Removing the tree
Lifting a limb off a roof without dropping it through the deck takes rigging and experience. The International Society of Arboriculture notes that removing storm-damaged trees is dangerous work best left to trained professionals.
Roofer
Protecting and repairing the roof
Tarps or temporarily closes the opening, then replaces broken decking, underlayment, flashing and shingles. Broken rafters or trusses may need a framing contractor or engineer, depending on the damage.
Emergency roof repairOther trades
Gutters, siding, interior
Crushed gutters, siding, drywall and insulation are separate trades. Note all of it in your photos so your claim covers the whole loss.
How Homeowners Policies Usually Treat Fallen Trees
Michigan DIFS says damage to your home from a storm or a fallen tree, and the resulting tree removal, is generally covered by a standard homeowners policy, subject to deductibles and policy limits. Your own policy decides the details, and the claim process is covered on our insurance claims page.
Tree removal is where people are often surprised. In the widely used ISO HO 3 special form (10 00 edition), tree removal is an additional coverage with its own caps. It pays up to $1,000 per loss, and no more than $500 for any one tree, to remove your trees felled by windstorm, hail or the weight of ice, snow or sleet, or a neighbor's tree felled by a covered peril, when the tree damages a covered structure or blocks a driveway or a ramp for a person with a disability. A tree that falls in the yard and hits nothing generally is not covered for removal.
The same form includes reasonable repairs to protect the property from further damage, which is why a tarp invoice belongs in the claim. It also excludes wear and tear and neglect. Long-term damage from a branch rubbing the roof for years is maintenance, not a sudden loss, and is unlikely to be covered.
Policies differ by company and edition. Read your declarations page and ask your agent; this is a general description, not a coverage opinion.
Dead Ash and Oak Wilt: Michigan Tree Problems That Reach the Roof
Two Michigan tree problems change the risk to a roof, and both are worth knowing before you hire a tree crew. The first is the emerald ash borer. The state's invasive species program says that since the beetle was first found in Michigan in 2002, it has killed tens of millions of ash trees in forests and neighborhoods. Purdue University Extension, which tracks the same beetle across the Midwest, warns that ash trees killed by emerald ash borer become extremely brittle and break easily as they decline, and that delaying removal lets the tree become more brittle and the problem more dangerous.
For a roof, that means a dead ash over the house is a sudden-damage risk, not just a debris problem. Brittle limbs can drop in an ordinary summer thunderstorm or under the first heavy, wet snow. A dead tree is also harder and more dangerous to take down, which is one more reason to have an arborist look at it while it can still be climbed or rigged safely. If the tree later falls, a policy's exclusions for neglect and wear may come up, so a written arborist opinion and prompt action help on that front too.
The second is oak wilt, a fungal disease that kills red oaks. Michigan's invasive species program says oak wilt spreads through root grafts and by beetles that carry spores to freshly pruned or injured oaks, and it tells owners not to prune oaks between April 15 and July 15. Moving firewood spreads it too.
That date window matters for roof work in practice. If an oak needs to be cut back from the roof, schedule the pruning for late summer, fall or winter, outside the April 15 to July 15 window. If a roof repair is booked for spring and a branch is in the way, ask the tree crew how they will handle it, rather than letting anyone on site simply cut it off. A storm-broken oak limb on the roof is a different matter: safety comes first, and the arborist can advise on the oak wilt risk of the broken limb.
Storm season and roofs
Thunderstorm wind, ice and the West Michigan events most likely to bring limbs down.
Michigan wind stormsKeeping Trees From Damaging the Roof
The cheapest roof repair is the one a pruning saw prevents. Trimming branches back from the roof stops rubbing, lets the shaded slope dry, cuts down on debris and takes away the bridge squirrels and raccoons use. The Michigan DNR recommends cutting tree limbs within a few feet of the roof for exactly that reason.
Large limbs over the house, dead wood and trees near power lines are jobs for a tree service, not a homeowner on a ladder. If branches are tangled in the wire that feeds your house, contact the utility rather than cutting them yourself.
- Have a tree service look at large trees over the house every few years, and after a major storm.
- Cut back limbs that touch or hang just over the roof before winter, when ice adds weight.
- Clear leaves out of valleys and from behind the chimney in late fall, or have it done.
- Watch the shaded slope for moss and treat it early.
- After any big wind, walk the yard and look at the roof from the ground for broken limbs hung up in the tree or on the roof.
Slow Tree Damage vs Sudden Tree Damage
| Slow (rubbing, shade, debris) | Sudden (falling limb or tree) | |
|---|---|---|
| What it looks like | Bald or scuffed shingles, moss, packed valleys | Broken shingles, holes, cracked deck, crushed gutters |
| Urgency | Fix before the next winter | Same day: protect people and the opening |
| Who goes first | Tree trimmer, then roofer | Utility if wires are involved, tree service, then roofer |
| Typical insurance view | Maintenance; usually not covered | Often covered, subject to policy limits and deductible |

Learn MoreQuestions We Hear
How close can tree branches be to a roof?
There is no single number in the code, but a common goal is to keep limbs from touching or resting on the roof and to trim anything that hangs just over it. The Michigan DNR recommends cutting limbs within a few feet of the roof to keep squirrels off. Large trees over the house deserve a tree service's opinion, since the risk is the whole limb, not just the leaves.
Who pays if my neighbor's tree falls on my house?
Often your own homeowners policy responds to damage to your house, and your insurer decides whether to pursue anyone else. The standard ISO form even addresses removing a neighbor's tree felled by a covered peril. If the tree was obviously dead and your neighbor had been warned, the answer can change. Ask your agent, and keep any written notice you gave your neighbor.
Can a small branch damage a roof?
Yes, mostly in two ways. A branch dropped from height can crack shingles or puncture them, especially in cold weather when shingles are stiff. A small branch that rests on the roof for months will scrub away granules where it moves. Neither may leak right away, so look at the spot from the ground or have it checked before winter.
Is a roof tarp after a tree strike covered by insurance?
Many policies cover reasonable repairs to protect the house from further damage after a covered loss. The ISO HO 3 form calls this Reasonable Repairs. Keep the invoice and photos of the tarp, and tell your adjuster it was done. Coverage depends on your policy, so confirm with your agent rather than assume.
Should I remove a tree that hangs over my roof?
Not necessarily. Many healthy trees can be pruned back so they no longer touch or shade the roof heavily. Removal makes more sense for dead or leaning trees, trees with large dead limbs over the house, or trees with signs of rot. An arborist can judge the tree's health. Your roofer can tell you what the tree is doing to the roof.
