It may be quite obvious to state this fact, but every single building structure needs a robust roof to cover up the structure and protect it from the outside elements (i.e. sun, rain, and wind). In fact, roofs acts as the first line of defence from the outside elements. It becomes obvious and not surprising that the roofing area is one of the biggest problem areas in the building structure as it is prone to continual wear and tear.
What’s even more frustrating is the fact that there are so many things that can go wrong in a roof if is not carefully built. Wrong choice of roofing contractor, quality of materials, and the team building it can lead to costly mistakes. So, what do you think can go wrong with a roof? Nope, its not just water ingress. Improper roof construction comprises of many mistakes, let’s us total the most common ones.
7 Common Mistakes To Avoid In Roof Construction
Brovary 1. Incorrect Or Poor Flashing
Flashing is one of the most important part of a roofing system. It is quite a common thing for a poor contractor to install low quality, inadequate, or misaligned flashing. The main role of flashing in roof construction is to protect the roofs joints and valleys, when of poor quality it puts your home at high risk of water leakage. Since your flashing protects your roof’s valleys and joints, this puts your home at risk of leaks. When incorrect or low-quality flashing is installed, your roof isn’t water-tight, which means over time water will penetrate thru these joints that will result in extensive damage to a building structure.

Ventilation is crucial for plummeting the total amount of humidity and condensation that builds inside the attic area of a building. Few builders ignore this factor which causes mold, fungus, and decay. It is crucial to allow cross ventilation to restrict excess moisture from building up.

In general, roofs witness a lot of rainfall, and when the roof is flat rainwater doesn’t have any way to drain out hence it sits on the roof. This isn’t good, as it can lead to leakages, or even worse, the entire roof may fall off. It is important to ensure that some type of drainage system is installed on the roof that supports the rainwater to drain down to the exterior of the building and doesn’t damage the roof or the structure.
4. Absence of Leak Barrier And Drip Edge
The drip edge or leak barrier helps in protecting a building structure from water damage. Many contractors avoid installing these to make profits. The drip edge stops rain from entering the under areas of the roof edge and also helps in preventing the fascia from rotting. On the other hand, the leak barrier strengthens more weak areas of your roof; together both these are vital components of roof construction.
5. Incorrect/Mismatched Shingles Installation
If a roofing contractor sources roof shingles from different manufactures, they are most likely to differ in color and shades. What’s even more important is the fact that these contractors sometimes purchase shingles that are low in quality just to save on costs. It is imperative to note that manufactures create shingles in batches and each batch has a distinct shade of color. Using low quality or different color shingles curbs down the overall performance and aesthetics of the roof.
6. Inappropriate Roof Coatings
Roof coatings differ from region to region; hence it is important to understand the system. In an area where humidity levels are high or rainfall levels are high an epoxy-based roof coating can be dangerous. This epoxy-based coating can curl up on its own, and bring the roof along with it. This can cause major damages and leak which ultimately make result in roof failures. To avoid serious roof issues, it is imperative to ensure you get the right roof coating.
7. Defective Nail Usage
When an inexpert roofing contractor drives faulty nails into a shingle at wrong angles, it damages the mats of the roof shingle. When a shingle is torn it becomes vulnerable to water invasion, which causes costly roof leaks.
These are common mistakes made during roof construction and are classically made by contractors who are inexperienced and unlicensed.
