Ask Nest

Not all roofing estimates are created equal. One might be a detailed 3-page breakdown with materials and warranties, while another could be a vague one-liner: "Roof replacement - $12,000."

If you’re collecting quotes, this guide will help you compare them apples-to-apples and avoid costly surprises. Nest Exteriors believes in total transparency — so here’s how to spot a strong estimate (and some red flags to watch out for).

✅ What a Good Roofing Estimate Should Include

Use this guide to identify what to look for in each of the following sections of a qualify roofing estimate. If one of these sections is missing or missing information, ask the roofer to provide it for you.

Scope of Work

What to Look For

Detailed breakdown of what's included: tear-off, disposal, materials, underlayment, flashing, ventilation, etc.

Why It Matters

Prevents surprises and ensures you're getting a full-system replacement, not just shingles.

Materials

What to Look For

Specific brands and product lines (e.g. CertainTeed Landmark PRO), quantities, and colors.

Why It Matters

Underlayment

What to Look For

Specifies synthetic vs. felt, and where ice & water shield will be installed.

Ventilation affects shingle lifespan, energy bills, and warranty validity.

Flashing

What to Look For

Notes whether flashing will be reused, replaced, or upgraded (step flashing, chimney flashing, etc.).

Why It Matters

Reusing old flashing is a cost-cutting shortcut that can cause leaks.

Warranty Info

What to Look For

Manufacturer and workmanship warranties, with timeframes and coverage details.

Why It Matters

Peace of mind and protection if issues arise post-install.

Cleanup & Disposal

What to Look For

Includes hauling away old roofing, magnet sweep for nails, and final walkthrough.

Prevents your yard from becoming a construction zone.

Timeline

What to Look For

Estimated project start and completion dates.
