Asphalt shingles are the most common roofing material for homes across the country. They’re affordable, reliable, and available in many styles and colors.
This guide walks you through when to repair or replace asphalt roofing, how to compare contractors, and what to expect during the project.
When Do You Need Asphalt Roofing Work?
You don’t have to wait for a major leak to think about your roof. Watch for these signs:
- Curling, cracked, or missing shingles – Wind and sun slowly break shingles down. If many shingles show damage, it may be time for replacement.
- Granules in gutters or at downspouts – Asphalt shingles shed their gritty surface as they age. Heavy granule loss means reduced protection.
- Dark patches or bald spots – These areas are more vulnerable to water and sun damage and may indicate worn-out shingles.
- Frequent leaks or water stains inside – Stains on ceilings or in the attic, peeling paint, or musty smells can point to roof issues.
- Sagging roof lines – A dip or wave in the roof could signal structural concerns that need prompt attention.
- Roof age – Many asphalt roofs last around 15–30 years, depending on shingle type and climate. If yours is near the end of its typical lifespan, plan ahead.
If you’re not sure, a visual inspection from the ground plus a professional assessment can tell you whether you need repairs, a partial replacement, or a full tear-off.
Types of Asphalt Roofing and Typical Costs
Most homes use one of two main types of asphalt shingles:
- Three-tab shingles
- Flat, single-layer shingles with a uniform look. - Generally the most budget-friendly option. - Often used on starter homes, sheds, or tighter budgets.
- Architectural (dimensional) shingles
- Thicker, layered shingles with a more textured, high-end appearance. - Typically longer warranties and better resistance to wind and weather. - Popular upgrade for curb appeal and resale value.
Cost factors for asphalt roofing include:
- Roof size and complexity (steepness, shape, number of levels)
- Shingle type and brand
- Removal and disposal of the old roof
- Underlayment, flashing, and ventilation upgrades
- Local labor rates and building code requirements
Instead of relying on a single estimate, it’s smart to compare a few detailed quotes from local roofing professionals. Look at what each quote includes: materials, labor, cleanup, and any added repairs.
How to Choose the Right Asphalt Roofing Contractor
A good roof depends as much on the installer as on the shingle brand. Use these steps to find a trustworthy pro:
- Confirm license and insurance
Ask for proof of current license (where required) and insurance, including liability and workers’ compensation. This protects you if an accident happens on site.
- Check experience with asphalt roofing
Look for contractors who install asphalt shingles regularly, not just occasionally. Ask how long they’ve worked with your preferred shingle type.
- Ask about manufacturer certifications
Some roofers are certified by shingle makers. This can be a sign of training and may qualify you for better warranty coverage.
- Review recent projects and references
Request photos of completed roofs similar to yours. Speak with a couple of recent customers about punctuality, cleanliness, and how issues were handled.
- Compare written estimates, not just prices
Each quote should clearly list: - Shingle brand, style, and color - Underlayment type - Flashing, ventilation, and drip edge details - Tear-off and disposal of old materials - Warranty terms and cleanup plan
- Protect your privacy while you shop
When gathering quotes, use a service that lets you compare options and chat with pros without sharing your personal contact info until you’re ready to move forward. This reduces unwanted calls and keeps you in control.
- Understand warranties
Ask about both: - Manufacturer warranty – Covers defects in the shingles. - Workmanship warranty – Covers installation issues. Get the length of coverage and what’s included in writing.
What to Expect During an Asphalt Roofing Project
Knowing the typical process will help you feel prepared and avoid surprises.
1. Inspection and proposal
The contractor will inspect your roof, attic (if accessible), and existing ventilation. You’ll review shingle options, colors, and any recommended upgrades. Then you receive a written proposal to approve.
2. Scheduling and permits
Once you sign, the contractor schedules your project and pulls any required permits. You’ll get an estimated start date and timeline, weather permitting.
3. Preparation at home
Before work starts:
- Move vehicles away from the house for access and safety.
- Take fragile items off walls or shelves that might shake during work.
- Cover attic items if your attic is unfinished; dust and small debris can fall.
- Let neighbors know about the upcoming noise and activity.
4. Tear-off and inspection
Most asphalt roofing projects begin with removing the old shingles and underlayment. Then the crew inspects the wood sheathing underneath. Any rotten or damaged sections are replaced before new materials go on.
5. Installation of the new roof
Typical steps include:
- Installing underlayment and ice/water protection where needed
- Adding or updating drip edge and flashing around chimneys, vents, and walls
- Installing new shingles, starter strips, and ridge caps
- Ensuring adequate ventilation (ridge vents, soffit vents, or other systems)
6. Cleanup and final walkthrough
At the end of the job, the crew should:
- Remove old materials and debris
- Sweep for nails with magnets around your yard and driveway
- Walk the roof and property with you to address any concerns
Get a final invoice and warranty documents for your records, and keep them with your home paperwork for future resale or insurance needs.
Asphalt roofing is one of the most important investments you’ll make in your home’s protection and curb appeal. By watching for early warning signs, comparing clear quotes from verified pros, and understanding the project steps, you can choose the right contractor with confidence—without giving up your privacy in the process.
