Having a new roof installed is a significant investment for any homeowner. Whether you’ve opted for a roof replacement or had a new roof built, the quality of the installation is key to ensuring the roof’s durability and your home’s protection. Once the roofers are done with their work, it’s essential to perform a post-installation inspection to ensure everything was done correctly and there are no hidden issues. In this guide, we will cover the essential things you need to check after roofers install a new roof.

1. Check the Roof for Visible Damage

Once your roof is installed, one of the first things you should do is perform a visual inspection. Look for any obvious damage or flaws, such as:

  • Cracked or missing shingles: If the shingles are cracked, curling, or missing, it’s a sign that the installation might have been rushed or improperly done. These issues can lead to water damage or leaks.
  • Loose or improperly aligned shingles: Check if the shingles are aligned properly. Misaligned shingles can leave your roof vulnerable to wind damage and leakage.
  • Dents and marks on the roof surface: Check for any unusual dents, marks, or scuffing that could indicate rough handling during installation.

2. Inspect the Flashing

Flashing is crucial to ensuring your roof is watertight. It is installed around areas like chimneys, vents, and skylights to prevent water from seeping through the roof’s joints. After installation, it’s important to check the following:

  • Proper installation: The flashing should be installed tightly against the surfaces it’s sealing. Gaps or loose flashing could lead to water infiltration.
  • Signs of rust or damage: Flashing is typically made of metal, so rust can form over time. Ensure the flashing is in good condition and free from corrosion.
  • Seam and joint integrity: The seams where the flashing meets the roof should be properly sealed to prevent leaks.

3. Check for Proper Ventilation

Roof ventilation plays a crucial role in regulating temperature and moisture levels in the attic. Poor ventilation can lead to a host of problems, including mold growth, wood rot, and reduced lifespan of the roof. After installation, inspect the following:

  • Proper placement of vents: Ensure that ridge vents, soffit vents, and gable vents are properly installed and positioned. These vents should allow for proper airflow throughout the attic.
  • Unobstructed vents: Check that there are no obstructions like debris, insulation, or dust blocking the airflow through the vents.
  • Balance between intake and exhaust vents: A balanced ventilation system is key to preventing moisture buildup. If the intake and exhaust vents are unbalanced, it can lead to problems like condensation.

4. Inspect the Gutter System

The gutter system plays a critical role in directing water away from the roof and the foundation of your home. When inspecting your new roof, make sure to check the following:

  • Proper alignment of gutters: Ensure that the gutters are level and aligned properly so that water flows toward the downspouts without pooling or overflowing.
  • Secure attachment: The gutters should be securely fastened to the roof and fascia to prevent sagging or detachment. 
  • Downspouts are clear and properly placed: Check that the downspouts are properly installed and directed away from the home’s foundation to prevent water damage.

5. Check for Proper Roofing Nails

Roofing nails are used to secure shingles and other roofing materials.

Roofing nails are used to secure shingles and other roofing materials. It’s essential that these nails are properly placed during installation. Look for:

  • Exposed nails: Make sure no nails are sticking up above the shingles, as they can allow water to enter the roof and cause leaks.
  • Nails placed correctly: Roofing nails should be placed in the proper spot, just below the adhesive strip on the shingle. Improper nail placement can lead to wind uplift and shingle damage.
  • Proper number of nails: Each shingle should have the correct number of nails (usually four) to ensure it stays in place. If nails are missing or too few, it can compromise the roof’s stability.

6. Look for Shingle Overhang

Shingles should overhang the edge of the roof slightly to direct water into the gutters. However, they should not overhang too much, as this can cause them to bend or tear off in strong winds. Check the following:

  • Even overhang: Ensure the shingles have an even overhang around the perimeter of the roof, typically around 1/2 to 3/4 inch.
  • Proper edge sealing: The edge of the shingles should be sealed with adhesive to prevent wind uplift and water infiltration.

7. Check for Proper Roof Slope

The slope, or pitch, of the roof, affects the drainage and overall performance of your roof. A roof with too steep or too shallow of a pitch can cause water to pool, leading to leaks. Check the following:

  • Even pitch: Ensure that the roof has a uniform slope across the surface. Uneven roofing can result in water pooling in certain areas, potentially leading to leaks.
  • Proper drainage: Water should flow easily from the roof to the gutters without pooling. If you notice areas where water doesn’t drain properly, the slope may be incorrect.

8. Test for Leaks

After the installation is complete, testing the roof for leaks is crucial. The best way to do this is by waiting for a heavy rainstorm and inspecting your home for any signs of water leaks. However, if you don’t want to wait for rain, you can simulate the effect by using a hose to spray water over different sections of the roof. Look for:

  • Wet spots on the ceiling or walls: These can indicate leaks that need to be addressed.
  • Water in the attic: If you notice water dripping from the attic, it could be a sign of roof failure or improper sealing around vents and flashing.

9. Review the Roofing Materials

Ensure that the roofing materials used match the specifications in your contract. You should also check that the materials appear to be of high quality and have been properly stored to avoid damage before installation. Key things to look for include:

  • Shingles or tiles: Make sure the material looks uniform, and there are no visible defects or damage.
  • Underlayment: The underlayment should be installed correctly and not be damaged, as it provides a secondary layer of protection against leaks.
  • Proper insulation: If insulation is part of the roofing system, check that it’s installed properly and securely.

10. Ensure Clean-Up Was Done Properly

After the roof installation is complete, the roofers should thoroughly clean up the work site. A good roofing company will leave your property in excellent condition. Check the following:

  • Nails and debris: Ensure that all nails, shingles, and debris have been cleaned up from the roof and yard. Leaving nails behind can be hazardous to you and your family.
  • Magnetic sweep: If necessary, the roofing crew should use a magnet to pick up any stray nails and prevent them from ending up in your lawn or driveway.

11. Review the Contract and Warranty

Finally, after checking the physical aspects of the roof, it’s important to review your contract and warranty. Ensure that the following are in order:

  • Warranty coverage: Make sure that the roofing company provides a warranty on both materials and labor. The warranty should cover any potential issues that may arise after installation.
  • Contract terms: Review the contract to confirm that everything was done according to the agreed-upon terms, including the roofing materials, scope of work, and payment schedule.

Conclusion

Inspecting your new roof after installation is an essential step in ensuring its long-term performance and protection. By checking for visible damage, verifying proper installation of flashing, gutters, and ventilation, and ensuring the quality of materials and workmanship, you can ensure that your investment is well-protected.

Remember, if you notice any issues during your inspection or feel unsure about the quality of the installation, don’t hesitate to contact the roofing company for clarification or repairs. A reputable roofing company will be more than willing to address any concerns and make sure your roof is installed correctly.

Regularly checking your roof and performing maintenance will also extend its lifespan and help you avoid costly repairs down the line. By staying proactive, you can keep your home safe and secure for years to come.
