Rooftop wireless installations operate under different technical, structural, and regulatory conditions than ground-level tower leases. SCM Advisors provides independent engineering review and lease advisory specifically for building owners navigating carrier agreements on vertical infrastructure.
A rooftop cell site places active RF equipment on a structure you own, in proximity to occupants you are responsible for, under lease terms written by a carrier whose priorities do not include your long-term interests. The technical complexity of a rooftop installation (antenna placement, cable routing, equipment cabinet placement, structural load, RF exposure boundaries) creates a category of risk that a standard commercial lease review is not equipped to evaluate.
Carriers have RF engineers who designed the installation. They have attorneys who drafted the agreement. They have project managers who have executed hundreds of rooftop deployments and know exactly where property owners leave value and liability on the table. SCM Advisors is the independent technical counterpart that building owners have historically lacked access to. That changes the dynamic of every negotiation, review, and inspection we are part of.
Rooftop antennas transmit at power levels regulated by the FCC under Maximum Permissible Exposure standards. On a rooftop with maintenance access, mechanical equipment, or occupied floors directly below, the geometry of that exposure matters. We assess antenna placement, transmission parameters, and access boundaries to confirm that installations comply with FCC OET Bulletin 65 standards and that your occupants and maintenance personnel are not operating in areas of elevated RF exposure without adequate controls.
Equipment cabinets, antenna mounts, conduit runs, and cable trays add structural load to a building that was not designed with wireless infrastructure in mind. We assess whether proposed or existing installations are consistent with structural capacity, whether mounting hardware is appropriate for the building type, and whether modifications over time have added load beyond what the original installation documented.
Rooftop sites are particularly vulnerable to incremental equipment additions that carriers install without formal amendment or renegotiation. A single antenna array becomes two. Equipment cabinets multiply. Cable runs expand. Each addition increases structural load, expands the RF environment, and represents a modification that should have triggered lease review and compensation adjustment. We conduct field inspections that document exactly what is installed and compare it against lease terms and permit records.
Carrier access to a rooftop intersects with building operations, tenant safety, and maintenance schedules in ways that ground-level tower leases do not. We review access provisions against the operational reality of your building and identify language that grants carrier personnel broader access than the installation requires or your building can accommodate without disruption.
Rooftop lease agreements contain provisions that have no direct equivalent in ground-level tower leases. Structural indemnification language. RF exposure liability allocation. Equipment removal obligations at lease termination. Co-location rights that allow carriers to add tenants to your rooftop without your renegotiation. Interference provisions that govern how carrier equipment interacts with existing building systems.
We review each of these with the technical context to evaluate what they mean in practice. A provision that looks protective in isolation can create significant exposure when read against how carriers actually operate rooftop installations over time.
Every engagement begins with a document review and site inspection. We evaluate the lease agreement, assess the installed infrastructure against lease terms and permit documentation, and deliver a written findings report that covers RF compliance, structural observations, equipment inventory, and lease provisions that warrant renegotiation or legal attention.
For new lease proposals, we review before you sign and identify terms that should be modified before execution. For existing sites, we establish a documented baseline of what is installed, what is permitted, and where the gap between the two creates exposure.
We advise commercial building owners, property management companies, REITs, municipalities with rooftop installations on public buildings, and attorneys representing building owners in rooftop lease disputes. Single-building owners and large portfolio operators receive the same depth of analysis. The installation on your rooftop does not know the difference, and neither do we.
Carriers bring their engineers to every rooftop negotiation. SCM Advisors makes sure you have yours. Independent RF review, structural assessment, and lease analysis before any agreement is signed or amended.
