Go-Over or Reroof: What’s the Right Choice for Your Roof?

All Weather Roofing and Waterproofing – Call 718-472-4424

When a roof reaches the end of its life, property owners are faced with an important decision: should they install a new layer of shingles over the old roof — often called a “go-over” — or perform a complete tear-off and reroof? At All Weather Roofing and Waterproofing, we help homeowners, business owners, and property managers across Queens and the greater New York City area understand the options, evaluate costs, and make the best decision for their property.

Both approaches have their advantages and drawbacks, and New York State building codes place clear restrictions on what can and cannot be done. This article breaks down everything you need to know about choosing between a go-over and a reroof.

What Is a Go-Over?

A go-over (sometimes called an overlay) is when a new layer of shingles is installed directly over the existing roof without removing the old shingles. It’s a faster, less expensive process because it avoids the labor and disposal costs associated with tearing off the existing roofing system.

In New York, go-overs are allowed under state and local codes, but only under certain conditions. Most municipalities, including New York City, permit no more than two layers of asphalt shingles on a roof. If your property already has two layers, you are required to do a complete tear-off before adding new shingles.

What Is a Reroof?

A reroof, or tear-off, involves removing all existing roofing materials down to the roof deck before installing new underlayment and shingles. This process allows roofers to inspect the decking, repair any rot or structural issues, and build a brand-new roofing system from the base up.

While a reroof requires more time and cost upfront, it typically provides a longer-lasting solution, better manufacturer warranties, and greater peace of mind.

Pros and Cons of a Go-Over

Advantages:

Lower Cost: Saves on labor and disposal fees.
Faster Installation: Without a tear-off, crews can complete jobs more quickly.
Less Mess: No old shingles and nails hauled away, reducing disruption to your property.

Disadvantages:

Shorter Lifespan: The new layer tends to wear out faster because it’s not installed on a clean deck.
Potential Hidden Damage: Decking issues like rot or mold go undetected since the old shingles cover them.
Weight Concerns: An extra layer adds hundreds of pounds of load to your roof structure. Older homes may not be designed to carry this weight safely.
Warranty Restrictions: Some manufacturers limit warranties on shingle products installed as overlays.

Pros and Cons of a Reroof

Advantages:

Longer Lifespan: A fresh installation on clean decking lasts longer.
Warranty Benefits: Most shingle manufacturers offer full warranty coverage when products are installed after a complete tear-off.
Structural Inspection: Decking, flashing, and underlayment can be inspected and repaired as needed.
Better Ventilation and Energy Efficiency: Allows for upgraded underlayments, ridge vents, and insulation improvements.

Disadvantages:

Higher Cost: Requires more labor and disposal, raising the price.
Longer Timeline: Projects may take several days instead of one or two.
More Disruption: Tear-offs involve more noise, debris, and staging of materials.

What the Law Says in New York

In New York State, including Queens:

You cannot exceed two layers of roofing. If you already have two, a full tear-off is required.
Roof overlays are only permitted if the decking is sound and free of rot, sagging, or water damage.
Some building inspectors may require tear-offs in certain neighborhoods or for specific building types, regardless of layer count.

At All Weather Roofing and Waterproofing, our team is fully up to date on New York codes. We’ll inspect your property and let you know whether a go-over is even possible, and if so, whether it makes sense for your specific situation.

Factors to Consider When Deciding

Roof Age: If your current roof is near the end of its lifespan, adding a go-over may not buy much time.
Existing Layers: One layer allows the option of an overlay; two layers require a tear-off.
Condition of Decking: Soft spots, sagging, or leaks beneath the shingles mean a tear-off is the only safe choice.
Budget: Go-overs cost less upfront, but reroofs provide better long-term value.
Curb Appeal: Tear-offs often look better since shingles lay flatter on a clean deck.
Resale Value: Buyers may prefer homes with a newer tear-off roof because of the warranties and assurance that hidden problems were addressed.

Cost Differences in Queens

Pricing varies depending on roof size, materials, and access, but here’s a general guideline for asphalt shingle roofs in Queens, NY:

Go-Over: Typically ranges from $350–$500 per square (100 square feet).
Reroof (Tear-Off): Generally $500–$900 per square, depending on underlayment, flashing, and decking repairs needed.

For example, a 2,000-square-foot residential roof may cost $7,000–$10,000 for a go-over versus $10,000–$18,000 for a full tear-off. While the tear-off is more expensive, it often lasts longer, provides stronger warranties, and increases home value.
