Tree Fell on Your House in San Antonio? What to Do in the First Hour

Immediate Emergency Actions: What to Do in the First 15 Minutes
If a tree falls on your house in San Antonio, your first priority must be life safety. Evacuate all occupants from rooms immediately underneath or adjacent to the impact zone. Heavy tree limbs can puncture rafters, collapse ceiling sheetrock, and sever hidden electrical wiring within seconds. Do not remain inside to inspect roof damage or retrieve personal belongings.
Once safely outside, survey the perimeter from a safe distance. Check for sparks, buzzing sounds, or downed electrical wires. If you smell natural gas or observe damaged gas meters, call 911 immediately. In Texas severe thunderstorm downbursts, trees frequently pull utility service drops from home weatherheads, energizing gutters, downspouts, and metal fences. Keep family members and pets at least 30 feet away from the structure until emergency personnel or utility crews confirm the area is electrically de-energized.
Assessing Electrical Lines & The CPS Energy Demarcation Line
Before any tree crew or homeowner can approach a damaged roofline in San Antonio, electrical hazards must be resolved. Understand the critical division of utility responsibility: CPS Energy owns and maintains high-voltage distribution lines along streets and public utility easements. If the fallen tree has pulled down or is entangled with primary power lines, CPS Energy emergency dispatch must cut power before anyone touches the wood.
Conversely, secondary service drops running from the pole transformer to your residential weatherhead are customer-side connections. While CPS Energy must disconnect service at the pole if the drop is torn down, they do not remove the fallen tree from your roof or repair bent weatherhead masts. Never attempt to lift branches off power lines with ladders, poles, or ropes. Green live oak and pecan wood is saturated with moisture and sap, making it an excellent conductor of lethal electrical current.

Documenting Structural Damage for Texas Homeowners Insurance
Texas homeowners insurance policies require prompt, thorough documentation of storm damage to process claims efficiently. Once the immediate emergency is stabilized, take detailed, date-stamped photographs and video of the scene from multiple ground angles before any branches are moved or cut.
Capture wide shots showing the entire tree and its relation to the home, as well as close-ups of specific structural punctures: cracked roof decking, crushed gutters, broken window frames, damaged soffits, and punctured drywall. If the tree originated from a neighboring property, photograph the stump or root plate location to establish property boundaries. Request an itemized storm mitigation invoice from your tree contractor that separates the cost of extracting the tree from the structure (covered under dwelling coverage) from yard debris haul-off.
Technical Tree Extraction: Why Crane Rigging & Friction Lowering Are Mandatory
Removing a multi-ton tree resting on a residential roof is an engineering challenge, not an ordinary tree cutting job. Cutting limbs under structural tension with a chainsaw without mechanical support can cause the trunk to shift violently, rolling further into living rooms or puncturing ceiling joists. This phenomenon, known as reactionary wood spring, poses severe crush hazards to workers and occupants below.
Professional arborist crews utilize heavy hydraulic mobile cranes or knuckle-boom loaders positioned on driveways using ground-protection distribution pads. Arborist climbers rig individual canopy sections to the crane hook using synthetic roundslings before severing branches. The crane then lifts the timber vertically off the roofline without applying downward friction or impact forces to damaged trusses, safely swinging wood to the street for chipping.
Emergency Roof Tarping & Secondary Water Infiltration Prevention
Once the tree weight is lifted from the roof, preventing catastrophic interior water damage becomes the primary objective. Sudden San Antonio squall lines frequently bring torrential rainfall immediately following damaging winds. Uncovered punctures in asphalt shingles, clay tile, or metal standing seam roofs allow hundreds of gallons of water to pour into attics, destroying insulation, electrical fixtures, and hardwood floors.
Our emergency tree crews provide immediate post-extraction weatherproofing. We clear splintered roof debris, sweep shingle grit, and secure heavy-duty 10-mil polyethylene tarps over punctured sections. Tarps are fastened with 1x2 wooden furring strips screwed into sound decking, never loose bricks or cinder blocks that can slide during subsequent gusts. Proper tarping satisfies your policyholder duty under Texas insurance law to mitigate secondary losses.
Common Questions Related to This Guide
Yes. Texas homeowners policies cover the reasonable cost to extract and remove a fallen tree that has damaged an insured structure such as your house, attached garage, or perimeter fence, subject to your policy deductible. We provide detailed line-item invoices for insurance adjusters.
