Managing commercial property in Southfield means going through the same ritual every spring: walk the lot, count the potholes, call for patches, then watch some of those same spots open back up before the next winter is over.
The patches are not the problem. The problem is that most pothole repair treats what is visible without touching what actually failed underneath it. That's why property managers who want a lasting fix turn to one of the best-rated asphalt paving services in the area instead of whoever quotes the lowest price. Asphalt Sargent has spent more than 20 years scoping commercial lots in this climate, and the pattern holds every time: a repair that ignores the base buys a season, not a fix.
What's Failing Under the Surface Before a Pothole Appears
Potholes do not form overnight, even when it feels that way after a hard winter. It starts with a surface crack that does not get filled. Water finds that crack and works into the base layer beneath the asphalt. From there, Michigan's winter takes over: the water freezes and expands, forcing the surrounding material apart, then contracts as temperatures rise. Repeat that cycle dozens of times across one winter, and the base has quietly lost the structural integrity it needs to carry vehicle loads.
The surface keeps carrying the weight of every car, truck, and delivery vehicle that crosses it without support underneath. The weakened section flexes, cracks, and eventually breaks apart. Traffic keeps moving over the exposed edges, and the hole grows. What started as a quarter-inch crack is now a pothole, and the cycle repeats because the base failure that caused it was never actually addressed.
Why Metro Detroit Sees This Every Single Spring
Southfield and the broader Oakland County area deal with more than 100 freeze-thaw cycles in a typical winter. It is not just the cold; it is the repetition. Temperatures swing above and below freezing again and again through the season, and each swing runs the freeze-thaw process through another cycle inside any pavement holding water beneath its surface.
The soil underneath makes it worse. Clay-heavy ground throughout Oakland County holds moisture far longer than sandy or well-draining soil, so a lot sitting on saturated clay that freezes solid in January can experience heaving force strong enough to crack even well-built pavement over time. Add heavy commercial traffic, winter road salt, and the occasional pass from a snowplow blade, and a Southfield lot is under more stress than most property managers account for until the damage is already significant.
Why the Same Patch Keeps Failing
The most common complaint we hear from commercial property managers is that they have repaired the same section of their lot two or three times in as many years. That pattern is one of the clearest signs a commercial parking lot needs repair at the base level, not just the surface. That pattern almost always means the base beneath those spots has failed. A cold patch fills the visible hole, but it does not rebuild the base layer that collapsed underneath it. Water gets in around the edges of the patch, the freeze-thaw process starts over, and the patched section fails again within months.
The repair that actually works starts below the surface: the failed section comes out, the base gets corrected, and new asphalt goes in over a properly compacted foundation. That costs more than a patch, but it ends the cycle. Property managers who have patched the same spot three times have often already spent more than a full base repair would have cost.

The Liability Question Behind an Unaddressed Pothole
A pothole in a commercial lot is not only a maintenance item. Anyone who trips at the edge of one, or damages a vehicle crossing it, is a potential claim against the property. For retail strips, office parks, and multifamily buildings in Southfield, the parking lot is often the first surface tenants, customers, and employees interact with.
This is general risk-management information, not legal advice, and how a specific claim plays out depends on the facts and your policy. What is broadly true is that a property with a documented maintenance record and a fast response to identified hazards is generally in a stronger position than one with no record at all. Property owners often ask how long asphalt lasts, and the honest answer is that freeze-thaw cycles, road salt, and sharp seasonal temperature swings shorten that lifespan considerably compared to milder climates, which is exactly why deterioration tends to show up faster than owners expect. Faded striping that makes accessible spaces or fire lane markings hard to read compounds the picture on top of the structural damage, which is one more reason to address deterioration as it develops rather than waiting for it to become an obvious safety issue.
What an Actual Pothole Repair Looks Like
Asphalt Sargent's process for commercial lot repairs starts with a site visit, not a phone estimate. The condition of the base under the damaged section matters as much as what's visible on top, and seeing the lot in person is what makes the scope and the price accurate.
For lots where damage is isolated, we repair those sections without tearing up the whole surface, and many commercial projects get phased so the business keeps part of its lot operational while work moves through other areas. Where the damage pattern points to wider base failure, we walk through the options before anything begins. Our team also handles concrete placement and repair, which matters for lots that include concrete aprons, curb stops, or walkways alongside the asphalt.
Frequently Asked Questions
Why does a pothole come back after it gets patched?
Because a cold patch fills the visible hole without rebuilding the base layer that failed underneath it. Water still gets in around the edges of the patch, the freeze-thaw cycle starts over, and the same spot opens up again, usually within a season.
How fast can a small crack turn into a pothole here?
A crack that looks minor in the fall can become a pothole by spring after one winter's worth of freeze-thaw cycles working the base apart. The timeline depends on traffic volume and how much water the crack lets in, but a single Michigan winter is often enough on its own.
Can a parking lot stay open during pothole repair?
Yes. Most commercial projects are phased so part of the lot stays accessible while work moves through other sections, with access routes and business hours worked out at the estimate visit.
Is pothole damage typically covered by property insurance?
That depends on the policy, so this is a question for your insurance agent rather than a paving contractor. What we can tell you is that a documented maintenance history tends to help a property's position if a claim comes up.
