Quick, low-risk steps

  1. Mark indoor leak locations and note when they appear (during or after rain).
  2. Use binoculars or ground-level photos to check for missing shingles, sagging, or flashing gaps.
  3. Collect your roof's age, material type, and any prior repair records.
  4. Ask two or more contractors to inspect and provide separate repair and replacement scopes.
  5. Compare bids using a checklist that includes decking, underlayment, flashing, and warranty terms.

Assess the Damage Safely

Start by observing from the ground or indoors. Look for water stains on ceilings, damp insulation in the attic, or daylight coming through the roof boards. These signs help you describe the problem to a contractor without putting yourself at risk.

Never walk on a roof that is wet, steep, or shows signs of sagging. Falls are a leading cause of home-related injuries. Instead, use binoculars or a camera with a zoom lens to inspect shingles, flashing, and vents from a safe distance.

  • Check attic for wet insulation, mold, or dark spots on wood.
  • Note if leaks happen only during wind-driven rain.
  • Look for missing, cracked, or curled shingles from the ground.
  • Inspect flashing around chimneys, skylights, and vents for gaps.
  • Document everything with date-stamped photos.

Key Factors in the Repair-or-Replace Decision

A roof's age and material are strong indicators. Asphalt shingle roofs in Atlanta typically last 20–30 years, but storm damage or poor ventilation can shorten that. If your roof is near the end of its expected life and has multiple issues, replacement may be more cost-effective than repeated repairs.

The extent of damage matters. A single missing shingle or small flashing leak can often be repaired. However, if leaks are widespread, decking is soft, or shingles are losing granules across the entire roof, a contractor may recommend replacement. Always ask for the reasoning behind their recommendation.

  • Roof age and material type (asphalt, metal, tile, etc.).
  • Number and size of leaks or damaged areas.
  • Condition of decking (soft spots, rot).
  • Presence of mold or moisture in attic insulation.
  • Your plans for the home (staying long-term vs. selling soon).

Get and Compare Detailed Bids

Ask at least two licensed contractors to provide written estimates for both repair and replacement options. Each bid should clearly state the measured roof area, materials, labor, and any assumptions about decking or structural work. This makes it easier to compare apples to apples.

Use a checklist to review each bid. Look for line items covering tear-off and disposal, underlayment, flashing, ventilation, permits, and warranty terms. A lower price may skip important steps like replacing all flashing or upgrading ventilation, which can lead to problems later.

  • Request separate repair and replacement scopes from each contractor.
  • Verify each bid includes measured area and pitch assumptions.
  • Check for decking allowance (cost per sheet if replaced).
  • Confirm permit and inspection costs are included.
  • Compare warranty length and what it covers (materials, labor, workmanship).

When Replacement Makes More Sense

Replacement is often the better choice when the roof has multiple layers of old shingles, widespread granule loss, or structural concerns like sagging. Building codes may limit how many layers are allowed, and a full tear-off lets the contractor inspect and repair the decking underneath.

If you plan to stay in the home for many years, a new roof can provide peace of mind and may improve energy efficiency through better ventilation and modern materials. For homes being sold, a new roof can be a selling point, but a repair might be sufficient if the roof is otherwise in good shape.

  • Multiple layers of existing roofing material.
  • Sagging or uneven roof planes visible from the ground.
  • Frequent leaks in different areas over the past year.
  • High energy bills possibly linked to poor attic ventilation.
  • Desire to upgrade to impact-resistant or more durable materials.

Common questions

What homeowners ask next

Can I just repair a few missing shingles instead of replacing the whole roof?

Yes, if the rest of the roof is in good condition and the damage is isolated. A contractor can match the shingles and replace only the damaged area. However, if the roof is old or has widespread wear, spot repairs may be a temporary fix.

How do I know if my roof decking is damaged?

Signs include soft spots when walking on the roof, visible sagging between rafters, or water stains on the attic side of the decking. A contractor will inspect the decking during a tear-off and replace any damaged sections, usually at an additional cost per sheet.

Will my insurance cover a roof replacement?

Coverage depends on your policy and the cause of damage. Storm damage is often covered, while wear and tear is not. Contact your insurer to discuss your specific situation and have a contractor document the damage for your claim.
