Home Inspector in Rochester Hills, MI

Rochester Hills is defined by its terrain, and terrain drives the inspection. This is genuinely hilly ground by Southeast Michigan standards, which means walkout and daylight basements are everywhere, lots slope in ways that either protect or endanger the foundation, and the Clinton River and its tributaries run through the city. Where a home sits relative to that grade matters more here than in almost any other community I serve.

Walkout basements are wonderful living space and a specific inspection concern. The walkout wall is a different structural and waterproofing condition than a standard foundation, and the transition points — where the walkout meets the buried wall, where the patio door sits, where the retaining wall carries load — are where I concentrate. Retaining walls in this city are common, load-bearing in some cases, and frequently failing from hydrostatic pressure and poor drainage behind them.

The housing stock runs from 1970s colonials through 1990s and 2000s larger homes, with pockets of older property closer to downtown Rochester. The newer large homes bring complexity: multiple HVAC zones, complicated roof geometry with many valleys and intersections, and elaborate exterior details that create more opportunities for water intrusion than a simple gable roof ever will. Complicated roofs are exactly where drone documentation earns its keep.

Pre-1970 pockets: Stony Creek, Brooklands, and the farm roads

Only about 18 percent of the housing predates 1970, but it is concentrated and distinctive. The Stony Creek village area near Van Hoosen Farm holds nineteenth-century houses; Brooklands, around Auburn and Hamlin, filled in with small 1940s homes; and the old farm roads still carry a few original farmhouses with additions from every decade since. Homes from this era commonly have stone or block foundations, galvanized supply lines, 60-amp services, clay laterals, and plaster over lath. On a Stony Creek house I spend extra time where additions meet the original structure and at the roof, because slate fails at the flashings long before the field. On a Brooklands bungalow, the panel and the plumbing under the kitchen tell most of the story.

1970s colonials, quads, and tri-levels

About 21 percent of the city went up in the 1970s, in the first big plats off Rochester Road, Avon, and Adams. Homes built roughly 1965 through 1973 can have aluminum branch-circuit wiring, which I confirm by reading the conductor markings in the panel and checking a sample of devices, and which needs a specific repair method rather than a shrug. Federal Pacific Stab-Lok and Zinsco panels turn up across the decade. Single-pane aluminum sliders and a furnace that is the second or third in the house are typical. Tri-levels and quads add their own item: a lower level half below grade on a slab often poured without a vapor barrier, which I check with the moisture meter before I trust the carpet.

1980s and 1990s subdivisions on the slopes

The 1980s were the peak decade here at about 27 percent of all housing, with another 17 percent in the 1990s, on the winding cul-de-sac plats that define most of the city. Homes from 1978 to 1995 can carry gray polybutylene supply piping, which I identify at the water heater, the meter, and under sinks. Beyond the walkout details covered above, this era commonly shows hardboard siding swelling at the butt joints, builder-grade double-pane windows with failed seals across the whole house, roofs at or past a second replacement, and 100 to 150 amp panels that have had a lot of circuits added for finished basements. I check the attic for bath fans that terminate in the insulation and run the thermal camera below every roof valley.

2000s infill, new builds, and the manufactured-home parks

About 17 percent of Rochester Hills housing was built after 2000, and roughly 1,800 units since 2010, mostly infill on the last open parcels and a few larger developments. Homes from this era commonly have complex roofs with dead valleys, multiple HVAC zones with dampers that have failed, high-efficiency furnaces with condensate and venting mistakes, PEX supply, and grading that settled toward the house once the builder left. For anything still under construction, a pre-drywall inspection and an 11-month warranty inspection are the two visits worth scheduling. The city also has about 4 percent manufactured homes, and I inspect those with attention to the piers and tie-downs, the belly wrap, the crossover duct, and the skirting ventilation.

Oakland County is EPA Radon Zone 2, and EGLE’s test results put roughly 30 percent of tested Oakland homes above the 4.0 pCi/L action level, three times the rate across the county line in Macomb. That is high enough that I recommend the test on every Rochester Hills basement, finished or not, and especially on walkouts, where the buried wall and the slab both sit against the soil that produces the gas. A 48-hour continuous-monitor test for $175 runs during the inspection window at the lowest livable level, and a mitigation system on a house that needs one is a routine negotiation item, not a reason to walk away.
