Arizona’s summer pavement temperatures can easily reach 160°F, which makes asphalt maintenance more than just a seasonal task.
For commercial properties in Tucson, maintaining a blacktop surface directly affects safety, lifespan, and your operating costs.
One of the most common questions property managers ask is: Should you patch damage or apply a sealcoat?
The answer depends on the condition of the pavement and the kind of wear it’s exposed to.
Eagle Rock Excavating uses high-performance products like Deery 220, MasterSeal MTR, and SealMaster PMM to prepare and protect commercial lots across Tucson.
When Is Asphalt Patch Repair Necessary?
Spotting Structural Damage Early
Patching is used when cracks, potholes, or failed areas in your asphalt reach a depth or size that can no longer be sealed.
These damages often begin small, but with Arizona’s extreme temperature swings, they can expand quickly.
If you’re seeing alligator cracking, sunken spots, or standing water that collects in uneven sections, it’s a clear sign that patching should come first.
What Is Involved in Asphalt Patch Repair?
Patching includes cutting out the damaged section, re-compacting the base, and laying new hot mix asphalt.
On commercial sites with heavier vehicles or foot traffic, repairs need to be precise to avoid future separation.
Deery 220 is a rubberized, hot-applied joint and crack sealant provides a solid barrier before resealing, especially helpful during Tucson’s dry months when pavement is more brittle.
How to Seal Asphalt After Repairs Are Made
The Role of Sealcoating in Asphalt Maintenance Arizona Properties Rely On
Sealcoating isn’t used to fix damage; it protects asphalt from sun, rain, and chemical spills after it’s been repaired.
Think of it as sunscreen for your pavement.
In Arizona, where UV exposure is high and rain arrives in strong, quick bursts during monsoon season, sealcoating helps limit surface oxidation and cracking.
Step-By-Step: How to Seal Asphalt the Right Way
After patching and filling cracks with Deery 220, the next step is applying a high-performance asphalt driveway sealer.
Eagle Rock Excavating uses MasterSeal MTR or SealMaster PMM based on your site’s usage:
- MasterSeal MTR is ideal for large commercial areas like distribution centers, as it contains ground tire rubber for added durability under heavy traffic.
- SealMaster PMM is better suited for places like malls and medical plazas, offering excellent adhesion and fast drying for high-use surfaces.
How Often Should You Seal Asphalt in Tucson?
Setting a Practical Maintenance Schedule
Most commercial lots in Arizona benefit from sealcoating every 2 to 3 years.
However, surfaces exposed to heavier use, like delivery zones, drive-throughs, or main drive lanes, may need it every 12 to 18 months.
Scheduling sealcoating during the spring or fall is ideal, as temperatures remain between 60°F and 90°F, allowing for proper curing.
Asphalt Sealing Cost vs. Repair: What You Should Budget For
Cost Breakdown
- Patching can range from $3 to $5 per square foot depending on depth and prep work.
- Sealcoating typically costs $0.10 and $0.16 per square foot, making it much more affordable when applied before major deterioration occurs.
Waiting too long on sealcoating leads to more frequent repairs, especially in high UV areas like Tucson.
It’s usually more cost-effective to sealcoat regularly than to repave.
Real-World Examples
- Retail Center Parking Lot – Sealed every 18 months, with Deery 220 used for early crack repair.
- Warehouse Facility – Needed patching in high-load zones before using MasterSeal MTR for added surface strength.
- Business Park with Light Traffic – Scheduled sealcoating every three years using SealMaster PMM, no major patching needed yet.
Is Sealcoating Worth It for Tucson Businesses?
Longevity, Curb Appeal, and Liability
Sealcoating reduces oxidation, keeps surfaces smooth, and makes it easier to clean up spills or remove painted lines during restriping.
It also boosts curb appeal and lowers the risk of tripping hazards or vehicle damage.
Regular maintenance like sealcoating can double the life of a commercial lot.

Why Arizona’s Climate Affects Asphalt Maintenance
Extreme Heat and Sudden Rain Matter
Arizona’s weather patterns aren’t just tough on people; they’re tough on pavement too.
Since summer asphalt temperatures can climb above 160°F, it makes surfaces brittle and more likely to crack.
Then monsoon storms roll in, cooling everything rapidly and stressing the material even further.
These extreme shifts create a cycle of expansion and contraction that speeds up surface aging. Ignoring this can lead to larger repairs down the road.
That’s why timing matters just as much as the products you use.
When to Schedule Sealcoating for Best Results
Pick the Right Season for Stronger Results
The best time to seal asphalt is during Arizona’s spring or fall, when daytime temperatures stay between 60°F and 90°F.
This range helps asphalt driveway sealer products like SealMaster PMM and MasterSeal MTR dry and bond properly.
Applying a sealcoat in the summer heat or right before a storm can lead to poor curing and wasted effort.
Eagle Rock Excavating always checks the forecast and surface conditions before starting work to avoid any setbacks and help your pavement last longer.
