The OverUnder Method™

Before you compare prices, you need to make sure you're comparing the same scope of work.

Most bids differ in:

• Materials (shingle quality, underlayment, ventilation)
• Scope (what's included vs omitted)
• Assumptions (repairs, disposal, flashing, etc.)

We adjust each bid to reflect equivalent materials and scope—so you're making an apples-to-apples comparison.

Many roofing quotes leave out critical components that only show up later as change orders or shortcuts.

Common gaps include:

• Underlayment quality
• Flashing replacement
• Ventilation upgrades
• Warranty differences
• Cleanup and disposal details

These omissions can make a bid look cheaper—but lead to higher costs or lower quality later.

Most homeowners compare bids based on price alone. But price without context doesn't tell you much.

We evaluate each bid across both:

• Cost
• Quality (materials, scope, contractor reliability)

This creates a clearer picture of what you're actually getting for your money.

The best option is rarely the cheapest—or the most expensive.

Instead, it's the bid where:

• Quality is strong
• Scope is complete
• Price is fair relative to what's included

We call this the Value Zone—where cost and quality are properly aligned.

Once you understand the full landscape of bids, you're no longer guessing—you have leverage.

We use that leverage to:

• Improve pricing
• Upgrade materials
• Clarify scope
• Strengthen warranties

Contractors are more responsive when they know their bids are being compared carefully.
