When it comes to asphalt roof repair, knowing what to do, and just as importantly, what not to do, can make the difference between a quick fix and long-term damage. Asphalt shingles are one of the most popular roofing materials in California and across the country, but even durable materials require careful handling when it’s time for a repair.
- Most common roofing material: Asphalt shingles are affordable, durable, and easy to repair, when done correctly.
- Avoiding mistakes: Poor repair techniques can cause leaks, void warranties, or shorten your roof’s lifespan.
- Trusted help: Working with a licensed contractor ensures safe, code-compliant repairs that last.
At Capstone Roofing Inc., we’ve seen firsthand how small issues become big ones when asphalt roof repairs are rushed or done improperly. This guide breaks down the most important dos and don’ts for maintaining and repairing your asphalt shingle roof.
🛠️ Why Asphalt Roofs Need Repairs Over Time
No matter how well-installed, every asphalt roof will eventually face wear and tear. Harsh sunlight, heavy rain, wind, and seasonal temperature shifts take their toll. Even well-maintained roofs can suffer from:
- Missing or lifted shingles
- Cracked or curling shingles
- Granule loss from aging
- Damaged flashing
- Nail pops or loose fasteners
- Minor roof leaks
The good news? Asphalt roof repair is often straightforward when handled promptly and professionally. Let’s start with what you should do when a problem arises.
⭐️ The Top Dos of Asphalt Roof Repair
Addressing problems the right way ensures the repair actually helps, not harms. Here’s what Capstone Roofing Inc. recommends for safe, effective asphalt shingle repairs.
Do Schedule a Professional Inspection
Before jumping to conclusions, it’s best to have your roof professionally inspected. What looks like a minor surface issue may actually stem from deeper structural problems or water damage. We inspect the full roof system, including underlayment and flashing.
Do Replace Damaged Shingles Promptly
Leaving cracked, missing, or lifted shingles exposed allows water to penetrate your roof system. Replacing them early prevents widespread damage to decking, insulation, or interior ceilings.
Do Match Replacement Shingles Correctly
It’s important to use shingles that match your current roof in size, color, thickness, and type. Improperly matched shingles can look uneven and may not seal or wear properly over time.
Do Use Roofing Cement for Sealing
If a shingle corner lifts or a small tear forms, roofing cement can help secure the area temporarily until a full repair is done. It’s also used under tabs to seal new shingles in place during a repair.
Do Secure Flashing During Repairs
Repairing shingles without inspecting flashing is a missed opportunity. Ensure flashing around chimneys, vents, skylights, or valleys is sealed, rust-free, and properly fastened.
Do Prioritize Safety
If you’re inspecting damage on your own, always use safety gear and avoid walking on steep, wet, or brittle roofs. Better yet, let professionals handle the repair using proper tools and techniques.
❌ The Biggest Don’ts of Asphalt Roof Repair
Avoiding common mistakes can prevent new leaks and extend the life of your asphalt shingles. Here are the key don’ts we advise all homeowners to keep in mind.
Don’t Use Nails Incorrectly
Incorrect nailing is one of the top causes of shingle failure. Don’t drive nails too high, too low, or through the shingle face. And never reuse old nails—always replace them to ensure a proper seal.
Don’t Apply New Shingles Over Damaged Ones
Layering new shingles over old ones might seem like a time-saver, but it can create uneven surfaces, trap moisture, and lead to faster deterioration. Always remove damaged shingles before installing new ones.
Don’t Patch Over Large Leaks Without Diagnosing the Cause
Covering a water stain or ceiling leak with caulk or roofing tape may hide the symptom, but not the source. Professional leak detection ensures repairs target the root cause, not just the result.
Don’t Walk On the Roof Excessively
Walking on asphalt shingles in hot weather can leave marks or loosen granules, and during cold weather, they can crack. Foot traffic should be limited, especially near the roof edge or peak.
Don’t Delay Repairs After a Storm
After high winds, heavy rain, or hail, small issues can worsen quickly. Waiting too long increases the risk of moisture damage, mold, or rotted decking beneath the shingles.
Don’t Attempt DIY Repairs Without Experience
Many DIY asphalt roof repairs lead to poor results, unsafe practices, or voided warranties. Unless you have roofing experience, it’s best to hire a qualified contractor like Capstone Roofing Inc.
👉 Common Types of Asphalt Roof Repairs
Whether caused by aging or weather, here are a few of the most common asphalt roof repairs we handle for California homeowners:

🤔 How to Know If You Need Asphalt Roof Repair
Spotting a roof issue early can save you time and money. Keep an eye out for these common warning signs:
- Visible shingle damage: Look for curling, cracking, or loose shingles, especially near roof edges.
- Ceiling stains or leaks: Water intrusion often begins subtly and worsens over time.
- Increased energy bills: Damaged roofs can reduce insulation effectiveness, raising heating or cooling costs.
- Moss or algae growth: Organic buildup holds moisture and can deteriorate shingles faster.
- Debris in gutters: Granules or broken shingle fragments in your gutters often signal wear.
