You can buy a weather-proof repeater kit and antenna for $400-$900 (depending on what you want). Example: Retevis RT97L GMRS Repeater Set, High Power Full Duplex Portable Kit with FRP Antenna & Coaxial Cable, Perfect for Farms, Warehouses, Remote Areas, Outdoors & Home https://a.co/d/02TYNVKV ($629.99) - Note: IP66 rating, so not entirely waterproof. QUESTIONS TO ASK YOURSELF: Can I get permission? (Who owns the building?) Where will the equipment "live?" (Will the box itself be inside the building (inside the rooftop access stairwell, for example. Or will it need to be in a cabinet outside? If inside the building, will the owner allow holes to be drilled for the Coaxial Cable?) How will I protect it? (Grounding, lightning protection, surge protection, and battery backup.) How public do I want it to be? (Fully open, tone-protected, or permission-based access.) How will I maintain it? (Expect occasional site visits, troubleshooting, and equipment replacement. Will you need to schedule maintenance? What happens during emergencies? Will you require key-access? Can you get a copy of the key?) What's the exit plan? (If the building changes ownership or access is revoked, what happens to the repeater? What happens if you move?)
