Frequently Asked Questions

Do you charge for a roof repair or re-roof estimate?

No! All of our roof repairs and re-roof estimates are free of charge. We want you to be informed to make the best choice for your roof.

How much does it cost for a new roof?

The cost of a new roof can vary depending on several factors. Here are the key variables that affect roofing prices:

  1. Roof Size (Square Footage)
    • The larger the roof, the more materials and labor are required. Roof size is often the most significant factor affecting the total cost.
  2. Roofing Material
    • Different materials have varying costs.
  3. Roof Pitch/Slope
    • Roofs with a steep pitch or slope require more work to install and may need specialized equipment. A steep roof increases the difficulty of installation, which can drive up labor costs.
  4. Roof Complexity
    • A simple, flat roof will cost less than a complex roof with multiple angles, valleys, dormers, or skylights. These additional features increase both the time and effort needed for installation.
  5. Roof Decking Condition
    • If the existing roof deck (wooden structure beneath the roofing material) is damaged or rotting, it may need to be replaced before installing a new roof. This can add additional costs for materials and labor.
  6. Insulation and Ventilation
    • If your roof installation requires additional insulation or ventilation (e.g., installing ridge vents), these costs can add up. Proper ventilation is crucial to preventing heat buildup in the attic, so these are important for the long-term health of the roof.
  7.  Roof Features
    • Additional features like skylights, chimneys, or solar panel installations can increase the price due to the additional work required.
  8. Roof Warranty
    • Some roofing materials or contractors offer extended warranties that may raise the cost, but this can provide peace of mind and potential savings on future repairs.
  9. Insurance Coverage
    • If your roof replacement is due to storm damage or another covered event, your insurance policy might cover some costs, though this depends on your coverage and deductible.

By evaluating these factors, you can get a better idea of the total cost for your specific roof replacement. If you need help estimating your roof replacement based on these variables, we would be happy to help further!

How do I know when it’s time to replace my roof?

Knowing when to replace your roof can depend on several factors, such as the age of your roof, its condition, and the materials used. Here are some signs that might indicate it’s time for a replacement:

  1. Age of the Roof
    • If your roof is approaching or has exceeded its expected lifespan, it might be time for a replacement.
  2. Shingles are Curling or Missing
    • If shingles are curling, buckling, or missing altogether, your roof may be at risk for water infiltration, which could lead to structural damage.
  3. Granules in the Gutter
    • If you notice a lot of granules (tiny black bits) in your gutters, it’s a sign that your shingles are wearing out and the protective coating is being lost.
  4. Leaks or Water Damage
    • Frequent leaks or water stains on your ceiling or walls are clear signs that your roof isn’t doing its job. If leaks occur in multiple spots, it’s likely a sign that your roof has reached the end of its lifespan.
  5. Sagging or Drooping Roof
    • A sagging roof can indicate structural issues caused by water damage, wood rot, or even the roof’s weight. This is a serious problem that requires immediate attention.
  6. Moss, Mold, or Algae Growth
    • While this might not always indicate a need for a full replacement, significant moss, mold, or algae growth can damage shingles and compromise the integrity of your roof.
  7. High Energy Bills
    • If your energy bills have increased without a clear reason, it could be because your roof is no longer providing adequate insulation. This can happen if the shingles are damaged or if the attic ventilation isn’t working properly.
  8. Visible Light in the Attic
    • If you see daylight coming through your roof boards from inside the attic, it’s an indication that the roof is compromised and should be replaced.

If you notice any of these signs, it’s best to have a professional roofer inspect your roof. Sometimes, roof repairs can extend the life of your roof, but in some cases, replacement is the best option for long-term protection and peace of mind.

What are some roof maintenance best practices?

Regular roof maintenance is essential to prolong the lifespan of your roof and prevent costly repairs. Here are some key maintenance tasks to consider:

  1. Clean Gutters and Downspouts: Regularly remove leaves and debris to ensure proper water flow, preventing water backup damage to your roof and home.
  2. Inspect Shingles and Roof Surface: Check for missing, damaged, or curling shingles. Look for signs of wear or damage, such as cracks or blisters. Addressing these issues promptly can prevent leaks and further damage.
  3. Remove Debris from the Roof: Clear leaves, branches, and other debris to prevent moisture buildup, which can lead to mold growth and roof decay.
  4. Trim Overhanging Tree Branches: Cut back branches that are close to or touching your roof to reduce the risk of damage from falling limbs and to prevent debris accumulation.
  5. Inspect Flashing and Seals: Examine the flashing around chimneys, vents, and skylights for signs of damage or wear. Ensure seals are intact to prevent leaks.
  6. Check for Moss, Lichen, and Algae Growth: These can damage shingles over time. If present, consider a professional roofing company to remove them safely.
  7. Inspect Attic Insulation and Ventilation: Proper insulation and ventilation help regulate temperature and moisture levels, preventing ice dams and prolonging roof life.
  8. Schedule Professional Inspections: Have a roofing professional conduct a thorough inspection at least once a year and after major storms to identify and address potential issues early.

By performing these maintenance tasks, you can help ensure your roof remains in good condition, protecting your home and extending its lifespan.

Can I replace only the bad sections of my roof?

Yes, you can replace only the bad sections but you can not get a manufacturer’s warranty if you only do a partial replacement. Typically we recommend replacing the entire roof at once if the roof is nearing the end of its expected life.

How do I prevent ice dams on my roof?

Ice dams can cause significant damage to your roof and home, but with proper care and maintenance, you can prevent them. Here are some ways to prevent roof ice dams:

  1. Ensure Proper Attic Insulation
    • Why it helps: Adequate insulation keeps the heat inside your home, preventing the attic from warming up and causing snow on the roof to melt. This helps prevent the meltwater from refreezing at the eaves.
    • What to do: Add or improve insulation in your attic, especially along the roofline, to keep the temperature consistent throughout your roof. Aim for at least R-38 insulation (about 12 inches of fiberglass or cellulose).
  2. Improve Ventilation in the Attic
    • Why it helps: Proper ventilation ensures that cold air circulates through the attic, maintaining a lower roof temperature. This helps prevent the formation of ice dams.
    • What to do: Install soffit vents, ridge vents, or gable vents to promote airflow. This keeps the attic cooler and helps prevent melting and refreezing of snow.
  3. Seal Gaps and Leaks in the Attic
    • Why it helps: Gaps or leaks allow warm air to escape from the living areas of your home into the attic, warming the roof. This increases the risk of ice dam formation.
    • What to do: Seal any cracks or openings around ducts, pipes, and vents to stop warm air from rising into the attic. Use foam insulation, caulk, or weatherstripping to seal gaps.
  4. Install Ice and Water Shield
    • Why it helps: Ice and water shield is a protective underlayment that can prevent water from infiltrating your roof in case ice dams form.
    • What to do: When installing or replacing shingles, ask your roofer to use an ice and water shield on the eaves, valleys, and any other areas prone to ice buildup. This layer acts as a barrier to prevent water from seeping into your roof structure.
  5. Maintain a Clean Roof
    • Why it helps: A roof covered in snow and debris can trap heat and cause uneven melting, increasing the risk of ice dams.
    • What to do: After a snowfall, remove snow from the roof using a roof rake with a long handle. Make sure to remove any large accumulations of snow or ice near the eaves. Avoid using sharp tools to prevent damaging the shingles.
  6. Use Heat Cables
    • Why it helps: Heat cables can be installed along the roof’s edge to prevent snow from melting and refreezing at the eaves, reducing the chances of ice dams.
    • What to do: Install roof de-icing cables along the eaves and valleys of your roof to help melt ice and snow before they have a chance to freeze and form dams. These can be turned on when needed during cold spells.
  7. Check for Proper Roof Slope
    • Why it helps: Roofs that are too flat can trap snow and cause it to melt unevenly, which contributes to ice dam formation.
    • What to do: If you’re building a new roof or replacing an old one, consider ensuring it has an appropriate slope (typically around 4:12 or steeper) to allow snow to slide off more easily.
  8. Consider Gutter Guards
    • Why it helps: Gutter guards help prevent leaves, twigs, and debris from clogging gutters, allowing meltwater to flow freely off the roof.
    • What to do: Install high-quality gutter guards to prevent debris buildup and ensure proper water flow, reducing the risk of ice dams forming in the first place.

By addressing these areas, you can significantly reduce the chances of ice dams and protect your home from damage caused by water infiltration. Regular maintenance, particularly before winter sets in, is key!
