Roofing Ann Arbor's Student Housing and Apartment Stock
Downtown Ann Arbor's skyline is built largely on student housing density, tall residential buildings packed onto South State Street and the blocks around campus, leased almost entirely on a September-to-August cycle. Outside that downtown ring, older garden-style apartment complexes spread through Pittsfield Township and Ypsilanti carry a different roof profile entirely: lower, more spread out, and often original to a 1970s or 1980s construction era. We build a different plan for each, because a high-rise membrane roof over hundreds of occupied units and a low-slope roof over a garden apartment complex fail in different ways.
Downtown High-Rises Built for Student Density
Buildings like the ones along South State and the blocks around Central Campus were built to house as many students as possible per floor, which means the roof often carries a dense field of rooftop mechanical equipment serving stacked HVAC systems, elevator penthouses, and amenity spaces like rooftop lounges or fitness areas that some newer buildings have added. That amenity-deck trend adds its own wrinkle, since a rooftop lounge means foot traffic, furniture, and sometimes planters directly on or near the membrane, which is a different wear pattern than a standard mechanical-only roof.
Turnover Week Timing Around the Academic Calendar
Student housing has one hard constraint the rest of the multifamily market doesn't: leases turn over almost universally in late summer, and a building that's fully occupied through spring finals can be nearly empty for a few weeks before fall move-in. That window is often the best time to do disruptive roof work, but it's also short and shared with a long list of other turnover projects a property manager is juggling, from unit cleaning to elevator maintenance. We coordinate our schedule with the property's turnover calendar early, because waiting until the window opens to start planning means losing weeks of a very short opportunity.
For buildings where major roof work can't fit inside the turnover window, we phase around occupied floors instead, which means tighter noise coordination and access planning than a vacant building would need.
Low-Slope Roofs Over Occupied Units
A leak over an occupied apartment unit is a tenant relations problem as much as a maintenance one, and in a market where a large share of tenants are students and their families paying close attention to lease terms, a poorly handled leak response creates disputes that outlast the actual repair. We prioritize fast, watertight temporary response on any active leak, using emergency dry-in where needed, before moving to a permanent fix, and we document the timeline clearly enough for property managers to respond to tenant inquiries with real information rather than guesses.
- Turnover-week scheduling coordinated early with property management calendars
- Amenity-deck wear consideration on buildings with rooftop lounges or patios
- Phased, occupied-floor work where turnover timing doesn't cover the full scope
- Fast temporary dry-in response on active leaks over occupied units
- Balcony and walkway drainage review separate from the main roof field
- Freeze-thaw inspection focused on parapet and mechanical curb ice damming
Older Apartment Stock in Pittsfield and Ypsilanti
Garden-style apartment complexes outside the downtown core, many built decades ago in Pittsfield Township and around Ypsilanti, tend to have lower-slope roofs over individual buildings rather than one continuous field, which actually simplifies phasing since each building can be treated as its own project without shutting down the whole complex at once. These roofs are more likely to be on original built-up or early EPDM systems that have gone through partial patch repairs over the years, and we survey each building separately rather than assuming uniform condition across a multi-building complex, since maintenance history often varies significantly building to building.
Balconies, Walkways, and Amenity Deck Roofing
Beyond the main roof field, multifamily buildings carry a lot of secondary waterproofed surfaces: balconies, exterior walkways, and increasingly, rooftop amenity decks. These surfaces see foot traffic and furniture the main roof never does, and they wear differently, often needing traffic-rated coating systems rather than a standard membrane. We treat these as a distinct scope from the main roof survey, since a building can have a sound primary roof and still have failing balcony waterproofing causing leaks into units below.
Exterior walkways at older garden-style complexes deserve particular attention here, since they're frequently the only covered access to second- and third-floor units. A membrane or coating failure on a walkway deck doesn't just leak into the unit below it, it can turn the walkway itself into a slip hazard during Michigan's freeze-thaw months, when meltwater refreezes overnight on a deck that isn't draining the way it should. We check walkway drainage and coating condition separately from balcony surveys, since the two often wear at different rates depending on how much direct traffic and standing water each sees over a typical year.
Questions Property Managers Ask
How do you plan around such a short turnover window?
We coordinate with the property's turnover calendar early, before the window opens, so scheduling and material staging are ready to move the moment units clear out rather than losing days to planning after the fact.
Can roof work happen while units stay occupied?
Yes, when turnover timing doesn't cover the full scope, we phase work around occupied floors with tighter noise coordination and clear communication about access and timing.
Do rooftop lounges and amenity decks affect the roof underneath?
Yes. Foot traffic, furniture, and planters near a rooftop amenity space wear differently than a standard mechanical-only roof, so we factor that use into material choice and inspection frequency in those areas.
How do you handle leaks over occupied apartment units?
We prioritize fast temporary dry-in on any active leak and document the timeline clearly, since property managers need real information to respond to tenant concerns quickly.
Do you survey every building in a multi-building complex the same way?
No. Garden-style complexes often have different maintenance histories building to building, so we survey each one separately rather than assuming uniform roof condition across the property.
