What seemed like a straightforward flat-roof solar project turned into a long search for one homeowner who wanted panels to sit neatly on a garage without a bulky profile.
The situation points to a broader issue in rooftop solar: Even though flat roofs are common on newer garages and similar structures, homeowners using certain roofing materials can still struggle to find simple mounting systems.
Here's what to know
In a detailed write-up shared on Reddit, the original poster said putting solar on an EPDM flat roof was much more complicated than they had expected. By the time they documented the project, the system had been running for 72 days after roughly a year of design work, waiting, and installation. During that process, they explored in-roof concepts, considered a low-profile glued system available in the U.S., and eventually chose Nicholson integrated fixing points after their roofer recommended them.
The homeowner summed up the challenge plainly: "Flat roof solar installations sounded simple, but we quickly found that a clean, secure mounting solution for an EPDM roof is surprisingly difficult."
Because EPDM is common on garages and other modern flat roofs, the lack of low-profile mounting hardware affects a wide range of homeowners. For people trying to avoid bulky ballast systems or raised panels, limited options can drag out a project, make design decisions tougher, and potentially raise costs.
Despite the upfront work, more homeowners are opting for solar upgrades as it remains one of the best investments to save money on home energy costs over time.

More background
Keeping the installation visually subtle was also a major priority. The homeowner wanted the panels to remain flat rather than tilted so the view would stay unobstructed, and the array would blend more cleanly with the roofline.

What can be done?
For homeowners with flat roofs, the first step is to ask installers very specific questions: What mounting systems work with your roof membrane? Will there be penetrations? How will waterproofing and warranties be handled? And can the panels sit low enough to match your design goals?
