Asphalt driveways are a popular choice for homeowners in Grantham, New Hampshire, where the climate is known for cold winters, warm summers, and unpredictable shifts in between. The durability, smooth appearance, and cost-effectiveness of asphalt make it a practical option for residential properties. However, even the strongest driveway cannot withstand years of exposure to Grantham’s seasonal extremes without proper care. That’s whyasphalt driveways in Grantham NH require consistent seasonal maintenance to ensure longevity, safety, and value.
In this blog, we’ll explore how seasonal changes affect asphalt surfaces, why maintenance is critical, and what homeowners in Grantham can do to protect their driveways year-round.
Why Asphalt Driveways Need Seasonal Care
Unlike concrete, asphalt is flexible, making it better suited for the local freeze-thaw cycles. Yet this flexibility also makes it vulnerable to seasonal stress. Without preventative measures, weather can quickly shorten the lifespan of a driveway.
- Winter freeze-thaw cycles create cracks as water seeps in, freezes, and expands.
- Spring rains can worsen existing cracks and wash away protective sealant.
- Summer heat softens asphalt, making it more susceptible to oil and gas spills.
- Fall debris clogs drainage areas and traps moisture on the surface.
By understanding how each season uniquely affects asphalt, Grantham homeowners can plan the right maintenance schedule to extend the life of their driveway.
Winter: The Harshest Season for Asphalt
Grantham winters are unforgiving. When temperatures drop below freezing, any water that has entered cracks expands, widening those gaps. Over time, this cycle of freezing and thawing weakens the structure of the driveway.
- Snow and Ice Removal: Shoveling is essential, but metal shovels can cause scratches that lead to damage. A plastic shovel or snow blower is safer.
- Deicing Materials: Rock salt may seem like an easy solution, but it can accelerate deterioration. Safer alternatives like calcium magnesium acetate should be considered.
- Preventive Crack Filling: Sealing cracks before the first snowfall keeps water from seeping in and expanding.
Homeowners who take these precautions can significantly reduce winter-related damage and costly spring repairs.
Spring: Repairing and Preparing
Spring in Grantham brings warmer weather but also heavy rains, which can worsen winter’s damage. This is the best time to inspect your driveway and perform necessary repairs.
- Drainage Management: Poor drainage can cause standing water, which weakens asphalt. Ensuring proper grading or adding a simple drainage solution can prevent long-term problems.
- Pothole Repairs: Even small potholes should be fixed immediately. Left untreated, they expand and pose hazards for vehicles and pedestrians.
- Sealcoating Preparation: Spring is the ideal time to schedule sealcoating for late spring or early summer. Sealcoating protects asphalt from UV rays, rain, and vehicle fluids.
Addressing spring maintenance needs promptly restores your driveway after the harsh winter and prepares it for the hotter months ahead.
Summer: Heat, Sun, and Heavy Use
Summer in Grantham may not bring extreme heat compared to southern states, but the sun’s UV rays can still cause significant wear and tear. Prolonged exposure to sunlight oxidizes the asphalt, making it brittle and prone to cracking. Add to this the weight of cars, trucks, and outdoor activities, and summer becomes a season of heavy stress on driveways.
- Sealcoating: This protective layer acts like sunscreen for your driveway, preventing UV damage. A properly sealed driveway lasts far longer than one left exposed.
- Cleaning Spills: Gasoline, motor oil, and other fluids soften asphalt. Prompt cleaning with mild detergent and water helps prevent permanent damage.
- Managing Heavy Loads: Parking heavy vehicles like RVs on asphalt for long periods can cause depressions. Using support boards under tires distributes the weight more evenly.
Summer is the best time to carry out larger maintenance projects because of favorable weather conditions.
Fall: Prevention Before Winter
Fall in Grantham provides the perfect opportunity to prepare your driveway for the upcoming freeze-thaw cycle.
- Final Crack Sealing: Any remaining cracks should be sealed before the first frost. This prevents water infiltration during winter.
- Leaf and Debris Removal: Organic matter can trap moisture and cause stains, weakening the asphalt surface.
- Resealing if Needed: If the sealcoat has faded or worn thin, fall is an ideal time for another application.
Taking action in the fall helps ensure that your driveway is well-protected before the arrival of snow and ice.
The Long-Term Benefits of Seasonal Maintenance
Seasonal maintenance isn’t just about keeping your driveway looking neat; it’s about saving money in the long run. Small, consistent upkeep can extend the lifespan of an asphalt driveway by several years.
- Cost Savings: Preventative measures like sealcoating and crack filling are far cheaper than full driveway replacement.
- Curb Appeal: A well-maintained driveway improves the appearance of your property, boosting resale value.
- Safety: Smooth, damage-free driveways reduce the risk of tripping hazards and vehicle wear.
For Grantham homeowners, where seasonal weather is particularly intense, proactive care is more than just advisable—it’s essential.
Professional Maintenance vs. DIY
Some maintenance tasks can be handled by homeowners, such as cleaning debris or applying deicer alternatives. However, other services are best left to professionals.
- Sealcoating requires specialized equipment for even application.
- Pothole repairs need hot asphalt patching for lasting results.
- Drainage corrections often involve regrading, which should be managed by experts.
Relying on professionals ensures that maintenance is done correctly, extending the driveway’s life and saving money over time.
