How Monsoon Season Affects Asphalt in the Phoenix Metro Area

Arizona’s monsoon season is one of the most challenging times of year for property owners, business managers, and HOA boards. While these seasonal storms bring much-needed rain, they also create serious problems for asphalt surfaces across the Phoenix Metro area. Between intense heat, sudden downpours, and flash flooding, parking lots and driveways face constant stress that can lead to cracks, potholes, and costly repairs if left unaddressed.

At Sunstar Seal Coating, Inc., we specialize in helping commercial and residential clients protect their pavement from monsoon season asphalt damage in Phoenix, AZ. With years of experience serving Glendale, Peoria, Mesa, Scottsdale, Chandler, and surrounding communities, our team understands exactly how rain affects asphalt in Arizona and what steps property owners can take to keep their surfaces durable, safe, and attractive all year long.

Understanding the Arizona Monsoon Season

Monsoon season in Arizona typically runs from June through September. During this period, extreme heat and dry conditions can quickly turn into torrential downpours, lightning storms, and high winds. The rapid change between hot, dry weather and sudden heavy rain places asphalt surfaces under enormous stress.

Unlike other regions that experience more gradual weather changes, the Phoenix area faces flash flooding that can leave standing water on parking lots and roadways. The combination of heat, moisture, and pressure often causes cracks and surface deterioration.

These conditions make regular asphalt maintenance in the Phoenix Metro area a necessity rather than an option.

How Rain Affects Asphalt in Arizona

Many people assume asphalt is waterproof, but it is actually porous. Over time, sun exposure and vehicle traffic cause small cracks to form in the surface. When monsoon rains arrive, water seeps into these cracks and weakens the base layers beneath.

Here is what happens next:

1. Water Penetration: Rainwater enters the smallest surface openings and expands the cracks.

2. Erosion Beneath the Surface: The water begins washing away fine materials that support the pavement.

3. Temperature Fluctuations: Hot daytime temperatures followed by cooler rain cause the asphalt to expand and contract, worsening the damage.

4. Pothole Formation: As water sits beneath the surface and vehicles pass over, the asphalt weakens, leading to potholes or surface collapse.

Understanding how rain affects asphalt in Arizona is the first step in preventing major structural damage. Without timely asphalt repair in Glendale, AZ, a small crack can quickly become a large and expensive problem during the monsoon months.

The Dangers of Standing Water

During heavy rainfall, low-lying parking lots or driveways can develop areas of standing water. This is one of the biggest threats to asphalt integrity. When water remains on the surface, it not only accelerates wear and tear but also creates safety hazards for pedestrians and drivers.

Pooling water can lead to:

• Hydroplaning risks for vehicles.

• Weakened asphalt layers from water infiltration.

• Increased cracking due to pressure and uneven load distribution.

• Erosion of painted lines and markings that reduce visibility and curb appeal.

To prevent this, Sunstar Seal Coating, Inc. recommends inspecting your property before the rainy season begins. Ensuring proper drainage, grading, and maintenance helps minimize the impact of heavy rainfall.

Common Signs of Monsoon Season Asphalt Damage

Property owners in the Phoenix Metro area should be on the lookout for visible signs that their asphalt has been damaged by the elements. Early intervention prevents more costly repairs down the road.

Common symptoms include:

• Surface cracking or alligator cracking: A web-like pattern indicating water infiltration.

• Potholes: Formed when the sub-base becomes unstable from erosion.

• Faded color or oxidized surface: Caused by sun exposure combined with rainwater washing away protective layers.

• Drainage problems: Water pooling in low spots after storms.

• Raveling: Loose gravel and aggregate coming off the surface.

If you notice any of these problems, it is time to schedule asphalt repair in Glendale, AZ, or a nearby service area before the damage worsens.

How Sealcoating Protects Asphalt During Monsoon Season

One of the most effective ways to guard against monsoon season asphalt damage in Phoenix, AZ, is through regular sealcoating. This process adds a protective layer that shields the pavement from water penetration, UV exposure, and chemical spills.

Key Benefits of Sealcoating Include:

• Moisture Barrier: Prevents rain from seeping into cracks and damaging the foundation.

• UV Protection: Reduces fading and brittleness caused by the intense Arizona sun.

• Enhanced Appearance: Restores a clean, dark finish that improves curb appeal for commercial properties and residential driveways.

• Extended Lifespan: Reduces long-term repair costs by preserving the structural integrity of the pavement.

At Sunstar Seal Coating, Inc., we provide high-quality sealcoating services in Phoenix using premium materials and professional application techniques. Our team recommends resealing every two to three years, depending on traffic volume and weather exposure.

The Importance of Preventative Maintenance

Monsoon season may be unpredictable, but preventative maintenance helps ensure your asphalt is ready for anything. Regular inspections and routine upkeep allow you to identify small issues before they become major repairs.

Essential Preventative Steps:

1. Crack Sealing: Filling small cracks prevents water from entering and expanding under the surface.

2. Drainage Assessment: Ensuring proper slope and stormwater flow keeps water from pooling.

3. Sealcoating: Reinforces protection against UV rays and water damage.

4. Pothole Patching: Fixing potholes early prevents structural deterioration.

5. Re-striping: Maintaining visible markings improves safety and compliance for commercial parking lots.

By scheduling asphalt maintenance in the Phoenix Metro area before or after monsoon season, property owners can save thousands in future repairs.

The Role of Proper Drainage

No matter how well-maintained your asphalt is, it will still suffer damage if water cannot drain properly. Poor drainage allows water to collect in certain areas, breaking down the pavement from the inside out.

At Sunstar Seal Coating, Inc., we often help clients improve their drainage systems by:

• Regrading surfaces to promote runoff.

• Cleaning or repairing catch basins and drains.

• Installing new drainage channels where needed.

This proactive approach prevents water buildup and extends the lifespan of your pavement.

Post-Monsoon Repairs and Restoration

Once the rainy season ends, it is important to evaluate your asphalt for signs of damage. Post-monsoon repairs may include patching potholes, sealing cracks, and reapplying a protective sealcoat.

In some cases, resurfacing may be necessary if water has penetrated deeply enough to compromise the sub-base. Resurfacing involves adding a new asphalt layer over the existing surface, restoring strength and appearance without the cost of full replacement.

Sunstar Seal Coating, Inc. offers complete post-monsoon restoration services, including crack sealing, sealcoating, asphalt repair in Glendale, AZ, and full resurfacing. Our experienced team uses only the highest quality materials to ensure long-lasting, durable results.
