1. Why Choose a Flat Roof Mount
Flat roofs are one of the most common installation surfaces for Starlink terminals, particularly for commercial buildings, apartments, and RVs. A properly installed flat roof mount provides:
- Optimal sky view — Fewer obstructions compared to ground-level installation
- Security — Dish is out of reach, theft-resistant
- Clean aesthetics — No ground cables to trip over
- Signal quality — Higher elevation reduces interference from ground-level structures

4. Installation by Roof Type
TPO / EPDM / PVC Membrane Roofs (Commercial)
- Locate structural supports (joists/trusses) using blueprints or a stud finder
- Mark bolt positions and apply urethane sealant to each bolt hole
- Use rubber gaskets under the base plate to distribute load
- Bolt through the membrane into structural supports
- Apply a cover patch over the bolt heads using compatible membrane bonding adhesive
- Seal edges with roofing-grade sealant — not standard silicone
Critical: Do NOT penetrate the roof membrane without proper sealing. A single unsealed bolt hole can cause leaks that damage insulation and interior ceilings. Always use the included rubber compression gaskets.
Modified Bitumen Roofs
Modified bitumen roofs require a different approach. The material is thicker and more forgiving for penetrations, but still requires proper sealing:
- Cut a small cross in the bitumen surface at bolt locations
- Apply cold-applied bitumen adhesive around each penetration
- Install bolts through the base plate
- Apply additional bitumen patch over bolt heads
- Allow 24 hours curing before applying wind load
Metal Roofs
Metal roofs are the easiest flat roof type for mounting. Use standing seam clamps instead of drilling where possible:
- Standing seam clamp method — No roof penetration needed. Attach a 2 x 4 wood or aluminum base to the clamps, then mount the bracket on the base. Best for metal roofs with raised seams.
- Drilling method — Use self-tapping sheet metal screws with neoprene washers. Seal screws with polyurethane sealant.
5. Waterproofing & Roof Protection
Waterproofing Checklist
| Component | Waterproofing Method | Warranty Impact |
|---|---|---|
| Base plate to roof | Rubber gasket + urethane sealant | Preserves roof warranty |
| Bolt penetrations | Neoprene washer + sealant bead | Preserves roof warranty |
| Cable entry point | IP68 cable gland + lap sealant | Preserves roof warranty |
| Mount to terminal | Stainless steel hardware (no sealant needed) | N/A |
6. Frequently Asked Questions
Can I use a flat roof mount without drilling?
A: Yes, for metal roofs with standing seams, use seam clamps. For membrane roofs, weighted (ballasted) mounting systems are available but require approval from a structural engineer for roof load capacity.
How much weight can a flat roof mount hold?
A: Our standard mounts are rated for up to 15 kg static load. The roof itself must be able to support the combined weight of the mount and terminal (typically 3-8 kg total) plus snow load in winter climates.
Will the mount damage the roof membrane over time?
A: With proper installation using rubber gaskets and sealant, the mount should not damage the membrane. We recommend annual inspection of the sealant condition. UV degradation of sealant occurs in 3-5 years and reapplication may be needed.
