Roof flashing repair cost

Roof flashing repair costs $200 to $500 on average for skylights, chimneys, and vents. Completely replacing the flashing costs $400 to $1,000, including resealing and replacing the surrounding shingles. Flashing is often metal and repels water away from roof joints and fixtures.

Roof flashing repair cost
Type Average cost
Skylight $150 – $500
Chimney $200 – $500
Roof vent pipe $200 – $500
Roof valley $200 – $850

  • Skylight – Skylight flashing repair costs $150 to $500. Replacing the whole skylight costs $800 to $2,400.

  • Chimney Chimney repair costs $200 to $500 to repair flashing, while replacing flashing costs $300 to $1,500.

  • Vent pipe – Roof vent pipe flashing repairs cost $200 to $500, including re-sealing pipe caps. Pipe flashing prevents leaks at the joint where the pipe meets the roofing surface.

  • Drip edge – Replacing drip edge flashing costs $1 to $2 per linear foot and prevents water from going underneath the shingles at the roof's edge and rotting the fascia, soffit, or roof decking.

Roof vent repair cost

A roof vent boot repair costs $75 to $150 on a standard slope roof. A complete roof vent replacement costs $200 to $700 or between $7 and $15 per linear foot, depending on the size, type (eave, ridge, penetration, fan), and if it's exposed or covered by shingles.

*Minimum fees are $150 to $300. Extra costs may apply for replacing damaged shingles around the vent.

A detachable plastic, metal, or rubber vent boot seals the vent pipe to prevent a leaking roof, water stains, moisture damage.

Roof valley replacement cost

Roof valley replacement costs $200 to $850, depending on the length, roof slope, type (open or closed), and the number of shingles replaced. Repairing roof valleys requires removing nearby shingles, replacing flashing, install new shingles, and re-sealing.

Roof valley replacement cost - chart
Roof valley replacement cost - chart
Roof valley replacement cost
Type Average cost
Closed valley with asphalt shingles $200 – $600
Open valley with metal flashing $200 – $850

*Costs based on an average 10 to 12 square foot valley. Prices increase for more expensive roofing materials or two layers of underlayment.

  • Roof valleys are angled intersections that channel water down to the gutters, which are prone to leaks.

  • Closed valleys have a continuous layer of shingles with an ice and water shield lining below.

  • Open valleys have a stronger, metal strip lining that requires additional sealant.

Roof felt repair cost

Roof felt repair costs $300 to $1,400 for replacing up to 100 SF of underlayment, including new flashing and removing and reinstalling roofing. Roof felt underlayment replacement costs $0.75 to $4.00 per square foot for materials and labor, plus removing the old roofing to access the underlayment.

Roof felt repair cost - chart
Roof felt repair cost - chart
Roof felt repair cost
Material Average cost per square (100 SF)
Asphalt $300 – $1,200
Tiles $650 – $1,400

*Includes removing the old roofing and felt, installing underlayment, and installing new asphalt or the same tiles.

  • Underlayment is a water-resistant barrier that protects the roof when tiles or shingles blow off. Roofing felt lasts 15 to 30 years, and leaks occur when worn out.

  • Beware of contractors who say underlayment is unnecessary. The National Roofing Contractors Association (NRCA) recommends underlayment for all roofs.

Sagging roof repair cost

Sagging roof repair costs $800 to $2,500 to replace sections of roof decking and shingles up to 100 square feet. Fixing minor sagging roofs may only require additional support like rafter ties. Severe cases may require a full roof replacement and replacing rotted rafters.

Sagging roof repair cost
Sagging roof repair cost
Cost to fix sagging roof
Condition Average cost Includes
Minor $250 – $800
  • Replacing small sections of roof decking and shingles
  • Installing rafter ties
  • Removing pests
Average $800 – $2,500
  • Replacing sections of roof decking and shingles (up to 100 SF)
  • Installing additional rafter support
Extensive $3,000 – $8,000+
  • Replacing rotted rafters
  • Adding a new structural ridge beam or rafter ties
  • Installing a new roof

Sagging roofs are dangerous and require an inspection and design plan from a structural engineer costing $300 to $1,000. Higher costs apply for sizing a beam replacement.

Common causes for sagging roofs:

  • Excess weight – Snow, ice, debris, or multiple layers of shingles stress the roof structure.

  • Water damage – Moisture weakens the roof and causes beams to rot.

  • Pests – Termites in the roof deck, rafters, or sheathing weaken the supports.

  • Old age – Wear and tear of the roof sheathing or rafters have shifted out of place.

  • Improper installation – Wrong-sized rafters and beams or improper installation cause structural failures.

  • Improper ductwork – Contractors who remove too much of a home’s framing structure when installing ductwork can cause rafter damages and sagging.

  • Structure damage – Load-bearing walls with structural problems cause sagging in the area above the wall. Houses that have simply settled may only need a few shingles to hide the minor sag.

Average cost of roof repair by material

Roof repairs, roof-overs, and partial replacements cost $250 to $3,000 per square (100 SF), depending on the material.

Average roof repair costs by material

Should I repair or replace my roof?

Minor roof damages such as missing shingles, corroded flashing, or small leaks should be repaired. Roofs older than 20 years, repairs costing more than $3,000, or damage affecting more than 25% of the roof requires a full replacement.

Roof repair vs. replacement
Type Average cost Recommendation
Roof repair $500 – $1,500
  • Roofs less than 5 years old
  • No extensive leaks or deck damage
Partial roof replacement $2,250 – $5,000
  • Damage only on one side of the roof
  • Strong structure overall
  • Roof is around 5 years old, or warranty is shorter than the expected roof lifespan
Roof-overlay $4,800 – $9,600
  • Reduces lifespan 10% to 20%
  • Adds extra weight
  • Not ideal for high-wind areas
  • Most building codes only allow two layers
  • More work to remove later
  • Harder to find leaks
  • Can void roof's warranty
Full roof replacement $5,000 – $11,000

Getting roof repair estimates

Before hiring a roof repair company or new roofing contractor, follow these tips and ask the right questions.

  • Get three or more in-person estimates to compare. Beware of companies who recommend a full roof replacement when only repairs are needed.

  • Ask for recommendations from family, friends, and neighbors.

  • Read their reviews on HomeGuide, Google, and the Better Business Bureau (BBB).

  • Select a company that's been in business for five years or more.

  • Be careful with extremely low or high price quotes.

  • Ask for a clear written estimate and warranty.

  • Avoid large upfront payments. Instead, negotiate a payment schedule for large jobs.
