At T & J Xteriors and Roofing, we understand the critical role a well-installed roof plays in protecting your home. Recently, we were called to inspect a roof that, upon arrival, revealed several significant issues due to improper installation. This case study aims to highlight these problems and underscore the importance of regular roof inspections.

Roof Structure and Installation Issues

Incorrect Ridge Shingle Installation

During our inspection, we observed that the ridge shingles on the front part of the house, which is lower than the main ridge, were incorrectly installed. The shingles extended up the roof, which is not the correct method. Proper installation should ensure that ridge shingles overlap correctly, providing a seamless barrier against water infiltration and wind uplift.

Drip Edge and Underlayment Problems

The drip edge on the eave was installed over the top of the tar paper instead of underneath it. This improper installation can lead to significant water damage. The purpose of the drip edge is to direct water away from the roof and into the gutters, protecting the fascia and underlying wood from rot. When installed over the tar paper, water can seep under the shingles and cause damage to the roof deck.

Outdated Roofing Materials

We found that the roof, which is about 20 years old, was constructed using outdated materials that do not comply with current building codes. Modern roofs require an ice and water shield underlayment, but this roof had the old tar paper, which offers less protection against water infiltration, especially in colder climates where ice damming can occur.

Shingle Installation Defects

• Starter Strip and Shingle Staggering: The starter strip and shingles were not staggered correctly. Proper staggering is essential to ensure that water flows off the roof without seeping into the seams between shingles. The incorrect alignment observed can lead to premature wear and leaks.
• Wind Damage: There were signs of old wind damage, with several shingles creased and bent. This damage indicates that the roof has been subjected to wind uplift, which can cause shingles to loosen and eventually detach.

Fastener and Sealant Issues

We discovered that many of the exposed fasteners did not have sealant applied. This oversight can allow water to penetrate the nail holes, leading to significant water damage over time. Even small amounts of water infiltration can cause considerable damage if left unchecked.

Valley and Pipe Boot Concerns

• Valleys: The valleys were not cut correctly. They were cut on the wrong side, allowing water to flow under the shingles rather than being channeled off the roof. Properly installed valley cuts are crucial for directing water away and preventing leaks.
• Pipe Boots: Some of the pipe boots had cracks, which will likely expand over time, allowing water to penetrate into the attic and cause further damage.

The Importance of Regular Roof Inspections

This case underscores the importance of regular roof inspections to identify and address issues before they become severe problems. Here’s why you should schedule a roof inspection at least once a year:

1. Early Detection of Problems: Regular inspections can identify issues such as shingle wear, granule loss, and minor leaks before they escalate into major repairs.
2. Ensuring Code Compliance: Building codes and standards evolve. Regular inspections ensure your roof meets current requirements, which is crucial for the safety and value of your home.
3. Preventive Maintenance: Addressing minor issues promptly can prevent them from developing into costly repairs or necessitating a premature roof replacement.
4. Extending Roof Lifespan: Proper maintenance and timely repairs can significantly extend the lifespan of your roof, ensuring it provides maximum protection for as long as possible.

Conclusion

The issues identified in this inspection highlight the critical importance of proper roof installation and regular maintenance. Incorrect installations, such as the improperly placed ridge shingles and drip edge, as well as outdated materials and poor sealing practices, can lead to significant damage and reduce the lifespan of your roof.
