What is a common mistake made during roofing installation?

Failing to install underlayment properly is indeed a significant common mistake during roofing installation. The underlayment acts as a secondary barrier against water infiltration, providing essential protection for the roof’s structure and the interior of the building. If the underlayment is not installed correctly, it can lead to leaks and water damage, especially in areas prone to heavy rain or snow. Proper installation involves ensuring that the underlayment overlaps sufficiently at edges and seams, which is crucial for maintaining a weather-tight seal under the shingles.

The importance of the underlayment cannot be overstated, as it also helps in reducing the risk of wind uplift and ensures that the shingles perform their intended function effectively. If just roofing shingles are installed without a reliable underlayment, it compromises the overall integrity of the roofing system, leading to potential repairs and increased costs in the future. Understanding this aspect is essential for any roofing contractor to deliver durable and effective roofing solutions.
