Not reliably if the sky is completely blocked. Satellite internet needs a radio line of sight between the user terminal and a satellite. A partial obstruction can sometimes be tolerated—especially by low-Earth-orbit services that can change satellites—but trees, roofs, poles, terrain and nearby buildings still cause interruptions whenever every available path is blocked.
For a real installation, the provider’s obstruction checker is more useful than a generic rule of thumb. It shows whether a specific location has enough usable sky, and it can reveal problems that are hard to judge from the ground.

What “a clear view of the sky” means
A satellite terminal exchanges radio signals with satellites moving through a particular part of the sky. Anything that occupies that path can weaken or interrupt the connection. The obstruction is not limited to the exact direction in which the dish appears to point at one moment; a low-Earth-orbit (LEO) constellation needs access to changing satellite paths as spacecraft move overhead.

In practical terms, that means the terminal must be able to “see” enough of the usable sky for the service’s antenna and network to maintain a link. A clear view is therefore an installation condition, not an optional performance tweak.

Complete blockage is a hard limit
A terminal inside a building, beneath a solid roof, in a basement, or surrounded on all sides by walls cannot maintain the required radio path. A window is not a dependable substitute: glass, framing and the building itself can block the changing directions a LEO service needs, and the terminal may not have the wide-angle view required by its provider.
Dense tree cover can create the same practical result. Even if a few gaps are visible, branches and foliage can occupy the paths used by successive satellites. A neighboring building, chimney, roof ridge or steep hillside can also create a permanent blind sector. If every usable path is blocked, satellite switching cannot restore service.
Partial blockage is a reliability problem
Partial obstruction does not automatically make a connection impossible. It does make the service less predictable. A terminal may work during one part of a satellite’s pass and drop when that satellite moves behind a branch or roofline. Seasonal foliage, tree growth and wet leaves can change a location that initially appeared acceptable.

Starlink’s installation guide states: “Your Starlink needs a clear view of the sky so it can stay connected with satellites as they move overhead. Objects that obstruct the connection between your Starlink and the satellite, such as a tree branch, pole, or roof, will cause service interruptions.” That warning applies even when the service appears to work most of the time.
Why a partly blocked Starlink site can still work
LEO systems can have several candidate satellites visible at once. Starlink says a U.S. user terminal may have “10s of satellites in view.” The terminal continuously detects surrounding obstructions and can switch between satellites many times per minute, routing through one with a more stable and unobstructed path.
That diversity can make a partly obstructed location usable for ordinary browsing or other tasks that tolerate brief drops. It is not a guarantee that trees or buildings are harmless. If all available satellites are hidden at the same time, the connection still interrupts. Activities that require continuity—video meetings, cloud sessions, online games and work VPNs—usually reveal short outages more quickly than web pages do.
Do not treat satellite switching as permission to install a dish under a canopy or between tall buildings. It is a resilience feature that reduces the effect of some obstructions while preserving the need for the clearest practical site.

How much sky does a Starlink terminal need?
Current Starlink support guidance describes a practical target of a clear view from about 20 degrees elevation above the horizon across a full 360-degree azimuth (all directions around the terminal). This is installation guidance for the cited Starlink system, not a universal specification for every satellite provider, orbit or terminal.
“Twenty degrees” is an angle, not a height measured in feet or metres. A nearby tree can rise above that angle even when it is shorter than a distant obstruction. Conversely, a distant ridge may remain below the usable part of the sky. The only reliable way to evaluate the combined effect of distance, height and direction is to put the terminal at the proposed location and run the provider’s obstruction test.
Use the obstruction checker before buying a mount
Starlink’s app includes Check for Obstructions. Use it at the exact place where the terminal would sit, not several metres away in an apparently similar spot. Walk around the proposed location while checking the view so you notice branches, poles, chimneys, rooflines, neighboring buildings and terrain in every direction.
The app’s obstruction map is the site-specific test. A generic claim such as “the dish can see through trees” or a fixed percentage of blocked sky is not a substitute; official sources do not publish one obstruction percentage or outage threshold that applies to every provider, location, terminal and plan.

Step-by-step: finding a workable installation location
- Place the terminal at the candidate site. Use the provider’s normal setup position and power it as directed. Do not rely on a view from inside the house or from a lower point if the final mount will be elsewhere.
- Run Check for Obstructions. Let the app scan the full surroundings. Read the resulting map rather than judging only the direction where you expect satellites to appear.
- Identify the physical blockers. Note branches, trunks, poles, chimneys, roof edges, neighboring structures and hills. Include objects that may move or grow, not just permanent construction.
- Match the result to your use. Occasional browsing may tolerate a brief interruption. Work VPNs, interactive calls, gaming and other continuous sessions need a much larger reliability margin.
- Test an elevated position if ground level fails. Move the test point to a roof, pole or wall location that raises the terminal above the obstruction. Run the checker again at that height; do not assume that a small increase will solve a wide obstruction.
- Choose compatible hardware. Select a mount rated for the terminal and the expected wind and weather at the site. Verify that the bracket, connector and cable routing match the terminal before purchasing or drilling.
- Check permissions and structure. Confirm building-code and zoning requirements, and obtain any lease, landlord or homeowners-association approval before permanent work. Make sure the roof, wall or pole can support the mount and its wind loading.
- Install and monitor. After installation, watch the obstruction map and outage pattern. Recheck after storms, construction or seasonal leaf growth, because a previously open path can become blocked.
When raising the terminal solves the problem
Elevation helps when the obstruction is local and finite: a roof ridge, nearby fence, low tree branches or a neighboring structure that blocks the horizon. Moving the terminal above that object can open the angles needed by the constellation.
A higher mount is not automatically better. It adds wind exposure, makes inspection and snow or ice removal harder, and can complicate grounding and cable routing. The mount must be appropriate for the terminal, the supporting structure and local weather. A pole attached to a weak deck or a roof installation that is not sealed correctly can create a structural or water-intrusion problem even when the radio view is excellent.
Roof mounting
A roof can clear nearby rooflines, trees and terrain. It also exposes the equipment to wind and makes future access more difficult. Confirm the roof’s construction, the mounting method and any required flashing or sealing details before work begins.

Pole mounting
A pole can lift the terminal above branches or a fence when there is a suitable structural attachment point. The pole, fasteners and supporting surface must handle the added leverage and wind load. Check that the cable can be protected along the pole and that the terminal remains accessible for service.

A wall mount can provide a stable elevated position without placing equipment at the roof peak. It still needs an unobstructed sector, adequate structural support and a cable route that does not damage the building envelope.
Choosing between locations and mounting solutions
| Decision factor | What to evaluate |
|---|---|
| Sky clearance | How much of the usable elevation and 360-degree azimuth is blocked by trees, roofs, poles, buildings or terrain. |
| Reliability requirement | Whether your work allows brief drops or requires stable video calls, gaming or VPN sessions. |
| Mounting height and structure | Whether a roof, pole or wall can raise the terminal above the obstruction while handling wind, weather, grounding and maintenance needs. |
| Rules and access | Building-code and zoning obligations, lease or landlord permission, homeowners-association rules and safe access for future service. |
| Provider and orbit | The provider’s own pointing and coverage geometry. Starlink’s 20-degree and 360-degree guidance should not be transferred automatically to a geostationary system or another terminal. |
Will satellite internet work under a roof or between buildings?
Under a solid roof, it should be treated as no: the roof blocks the radio line of sight needed for a dependable connection. A terminal placed inside a room, attic or enclosed balcony may occasionally detect a signal through a window or opening, but that is not the clear, wide-angle installation the service requires and should not be planned as a reliable setup.
Between buildings, the answer depends on the angle and movement of the obstruction. A narrow gap may allow a connection during part of a pass, then block it as the satellite moves. Tall buildings on several sides can remove so much of the usable sky that switching offers little benefit. Run the obstruction checker from the exact proposed point rather than inferring performance from a single visible patch of sky.

The app reports obstructions
Move the terminal temporarily to an open test point and run the scan again. If the obstruction map improves, the original location is the cause. Test a higher roof, pole or wall position, then compare the new map before committing to permanent hardware.
Service drops when a branch crosses the sky
A moving branch can block one or more satellite paths. Trim or remove the obstruction only when it is lawful and safe, or raise and reposition the terminal. Do not assume that a few clear minutes prove the location is adequate; correlate the drops with the branch movement and the obstruction map.
Interruptions appear after installation
Check for seasonal foliage, storm damage, new construction or a mount that shifted in wind. Re-run the provider’s obstruction check at the installed position. If the map is clear but interruptions persist, the cause may lie elsewhere in the service or equipment; the obstruction test narrows the diagnosis without proving that every outage is a blockage.

The ground location fails but no obvious higher point is available
Consider a professional installer who can assess structure, wind loading, cable routing and the obstruction geometry. Any permanent work still requires the relevant building, zoning, lease, landlord and association approvals.
LEO and geostationary services are not interchangeable
LEO services use satellites that move across the sky, so the terminal needs access to changing directions and can benefit from switching among multiple satellites. Geostationary services and LEO services have different pointing and coverage geometries. A clearance rule, mounting orientation or obstruction tolerance stated for one provider should not be applied to another without that provider’s documentation.

The Starlink app and its approximately 20-degree, full-azimuth target are useful for a Starlink installation, not a universal satellite-internet standard.
What approvals and safety checks come first?
Starlink’s terms place responsibility for building-code, zoning, lease, landlord and association approvals on the customer. Those obligations can determine whether a roof or pole is practical even when it produces the best radio view.
- Confirm whether a permit or inspection is required for the proposed mount.
- Get written landlord or homeowners-association approval when applicable.
- Verify that the roof, wall or pole is structurally suitable for the equipment and local wind.
- Plan protected cable routing and any required grounding according to local rules and the equipment instructions.
- Keep the terminal and mount reachable for maintenance without creating a fall or electrical hazard.
A satellite dish roof mount or pole mount can be the right accessory for clearing trees and rooflines, but it cannot compensate for a fundamentally blocked sky. Compatibility with the terminal and the supporting structure must be verified before purchase.
The practical answer for your site
If every direction above the terminal is blocked by a roof, dense canopy, buildings or terrain, satellite internet will not be reliable from that position. If only part of the sky is blocked, a LEO service may remain usable by switching satellites, but interruptions remain possible and become more disruptive for latency-sensitive or continuous work.
Test first with the provider’s obstruction tool. When the result is poor, raise or relocate the terminal, verify the mount and structure, and complete all required approvals. The app’s measured view at the final installation point—not a promise that satellite switching will “work through” obstacles—is the basis for a dependable decision.
