6 Common Roofing Mistakes That Occur During Installation

 

Your roof is one of the most critical structures in your home because it’s the first line of defense against the ravages of Mother Nature. Your roof also contributes to the energy efficiency of your home’s internal heating and cooling systems.

 

Roofing systems are very complex because they need to maintain structural integrity even through continual wear and tear. So many things can go wrong with a roof during the installation process, and unfortunately, correcting these mistakes can be very laborious and expensive.

 

Here are six common roofing mistakes that occur during installation:

 

1. Misaligned Flashing

 

Flashing is a thin sheet of metal installed underneath your roofing system to redirect water away from internal house structures. They prevent damage to vents, chimneys, skylights, and all other odd angles found on your roof.

 

Properly installing flashing is crucial to your roof’s performance. If it’s misaligned, or not fastened correctly, or if the proper parts don’t overlap, you can expect severe damage to your roof whenever it rains or snows heavily.

 

2. Reusing Flashing

 

It’s best practice to replace all flashing when installing a new roof. Even if the existing flashing looks to be in good condition, you can’t be entirely sure about its structural integrity, especially if it’s been on that roof for more than five years. To be sure of long-term stability, you should always use new flashing.

 

3. Nail Placement

 

Roof installation is an exact process because every nook and cranny needs to be sturdy and kept safe from encroaching moisture. Something as simple as imprecise nail placement can cause structural issues. If any part of a nail is left exposed, it will corrode and create holes in your roof shingles, leading to water damage.

 

Nail length should also match the type of roof shingle that you choose to ensure that it holds correctly. If you don’t use the correct nail, your shingles may end up loosening and shifting from their proper place.

 

4. Poor Ventilation

 

Roofing contractors are not only responsible for installing your roof. They should also keep in mind that the roof affects the ventilation inside the attic. One of the leading causes of roof decking failure is a poorly ventilated attic.

 

A closed-off, humid attic will lead to mold, fungus, and decay over a short amount of time. Cross ventilation is crucial to prevent moisture buildup and to ensure that the roof has a solid foundation to sit upon.

 

5. Absence Of Drip Edges

 

The roof’s drip edge is a barrier that stops water from entering vulnerable areas underneath the roof edge. It strengthens these weak areas and prevents roof fascia from rot and damage. Your roofing contractor should install drip edges on your roof and not avoid them for profit.

 

6. Wrong Roof Coating

 

The choice of roof coating depends on your location. If you live in a very humid area that gets a lot of rain every year, silicone roof coatings are the best choice for you. Epoxy and acrylic coatings will curl up and lose thickness under the elements and shouldn’t be used for your roof. To avoid serious roof issues, you should make sure your roof coating matches the climate that you live in.

 

Conclusion

 

Roof installation is a very complex process that needs to be done correctly every step of the way. Simple things like misaligned flashing, wrong roof coating, and even nail length can influence your roof’s structural integrity. This is why it’s important to hire highly experienced contractors for your roofing project.
