Repeat business is the most honest review a contractor can receive — and this Lebanon property owner has hired CPM ROOF four times in a single year. This latest project tackled a 30-square low-pitch rubber roof that had been leaking in multiple locations, coating the entire surface with Henry commercial silicone for a 15-year warranty that finally closes the door on a leak problem the property had been carrying. A solar-powered attic ventilation fan was also installed on the freshly coated surface. Combined with the previous projects completed this year, the homeowner’s entire property — business and residence — is now comprehensively protected for under $50,000 total. That’s the kind of value that explains why the same customer keeps calling back.
A Rubber Roof Past Its Prime
The before condition of this low-pitch flat roof tells a familiar story — an oxidized, granule-depleted surface showing the cracking, membrane fatigue, and penetration failure that develops on rubber roofing systems that have run past their effective service life. Multiple leak locations spread across a 30-square surface means the problem isn’t isolated to one failed penetration or one seam separation — it’s systemic deterioration that requires a comprehensive solution rather than another round of spot repairs. The deteriorated fascia edge detail visible on the building’s corner — peeling, failing trim with compromised flashing at the parapet — confirms the entire perimeter needed attention alongside the field coating.
Spot repairs on a roof in this condition buy months, not years. The Henry silicone system closes every vulnerability simultaneously rather than chasing individual failures one after another.
Why Silicone Was the Right Choice
Henry’s commercial silicone coating chemistry was selected specifically for this low-pitch application because silicone maintains complete waterproofing integrity even when water ponds on the surface — a condition that occurs regularly on low-slope roofs where drainage moves slowly after rain events. Acrylic coatings degrade under sustained ponding and eventually fail at exactly the points where water sits longest. Silicone doesn’t. For a 30-square roof with multiple former leak locations, that performance characteristic isn’t a bonus feature — it’s the reason silicone is the correct product for this application.
The bright white finish the Henry system produces also reflects solar heat rather than absorbing it, reducing the surface temperature of a low-slope roof that would otherwise collect significant heat through Ohio’s summer months.
Surface Preparation and Penetration Sealing
The original oxidized rubber surface required thorough cleaning before silicone application — removing the degraded granule layer, loose membrane material, and any contamination that would compromise adhesion between the existing substrate and the new coating. Every penetration across the 30-square field — the multiple pipe boots and vent bases visible in the before and after views — received individual detailing before the field coat was applied, ensuring the silicone membrane extends continuously through each transition rather than leaving exposed metal-to-membrane gaps that become the first failure points.
The parapet perimeter received coating treatment up the vertical face and across the cap, sealing the wall-top water entry paths that bypass field membrane protection entirely.
Solar Fan Installation on the Fresh Coating
A solar-powered attic ventilation fan was installed on the freshly coated white roof surface as part of this project — the black square unit mounted on a properly flashed curbed base set into the silicone membrane. The fan’s integrated solar panel powers the unit directly from sunlight with no electrical connection to the building required, addressing the ventilation deficiency that older construction in Lebanon’s historic downtown corridor consistently presents. For a property combining business and residential use, reducing heat buildup in the attic space directly improves comfort in the occupied areas below through Ohio’s summer months.
The installation sequence — coating first, fan curb set into fresh silicone second — ensures the penetration is properly integrated into the waterproof membrane rather than mounted over a completed surface that then requires field-modified flashing.
The Completed Surface
The finished roof surface presents a consistent, seamless white silicone membrane stretching across the full 30-square field — every vent penetration sealed continuously into the coating, the parapet walls treated at their cap surfaces, and the solar fan curb rising cleanly from the white field with its black housing in deliberate contrast. Viewed from the building’s elevated position looking out over Lebanon’s historic downtown roofscape, the completed white roof stands distinctly against the varied surfaces of the surrounding commercial buildings. The church steeple and mixed commercial rooflines of the East Main corridor visible in the background provide context for the building’s position in Lebanon’s business district.
A 15-year warranty now backs a surface that was leaking in multiple places before this project began.
Complete Property Protection Under $50,000
What makes this project noteworthy beyond the roofing work itself is the total value picture it represents. Four separate projects completed for the same Lebanon property owner in a single calendar year — covering both the business and residential components of the property — for under $50,000 combined. That total reflects a contractor relationship where the homeowner trusts CPM ROOF to identify problems accurately, propose appropriate solutions rather than over-specified ones, and deliver results that make the next call an easy decision. A 15-year silicone warranty on a previously leaking roof system is exactly the kind of outcome that produces a fourth project inside twelve months.
The consistent quality across each engagement — the solar fan, the silicone coating, and the projects that preceded them — is what builds the trust that turns one-time customers into repeat ones.
Commercial and Residential Flat Roof Solutions by CPM ROOF
Leaking low-pitch and flat roof systems on combined business-residential properties in Lebanon and the surrounding Dayton area need contractors who understand both the technical demands of commercial coating systems and the value of comprehensive, warranty-backed solutions that don’t require the property owner to call again in two years. CPM ROOF delivers that combination — from Henry silicone coating on 30-square rubber roofs to solar fan installation and complete property-wide protection packages.
