What Is Roof Flashing And Why Do I Need It?

Construction & Contractors Articles

You might not know it, but flashing is readily seen from basically anywhere on the exterior of the house. The foundation, the porch, etc. Essentially, wherever you see one material meeting another material on the exterior of your house, you will find flashing. However, the most important area where you will need flashing is the roof. Throughout the course of this guide, you will learn what roof flashing is and why you absolutely need it, learn what properly installed flashing looks like, as well as the problems with improper flashing and when the best time to replace flashing is.

What Is Roof Flashing?

The primary purpose of roof flashing is to ensure that you have a tight, waterproof roof. Without roof flashing, water could easily flow its way down your chimney's seams or between the tiles that are present on your roof. As such, this could create areas of moisture that will essentially rip up your roof from the inside out in addition to ruining the delicate interior of your home, where the water will navigate itself to.

Cement will simply not do an adequate job in filling the seams of this area and will still allow water to find its way into the interior of your home. As such, roof flashing is usually not constructed with cement but rather it is usually made of aluminum or galvanized steel.

What Does Properly Installed Flashing Look Like?

The good news is that properly installed flashing is not terribly intrusive. There's a reason that many people are not exactly sure what flashing is: When properly installed, it's not something that you particularly notice. In older homes, you may notice lead sheets used as flashing; this is not the case anymore, due to hazards associated with lead and zinc. There are usually replacement and artificial metals used in its stead. A properly installed flashing installation is properly fitted. That means it is cut to the exact specifications demanded by the areas in which one roof material meets another roof material.

What Problems Come From Improperly Installed Flashing?

If flashing is not installed or haphazardly installed, your house will become increasingly susceptible to water damage. It is important that you take the time to make sure that flashing is properly installed around your home. If not, then this could cause moisture to form underneath the tiles and shingles of your roof, which could lead to them uprooting themselves or algae and moss presenting on your roof. Inadequate flashing also means that the interior of your home could suffer from water damage.

When Should I Replace My Flashing?

There are several times or occasions when it might be necessary to replace your flashing. If you are ever having a new roof installed, it is highly recommended that you also have new flashing installed. Why is this the case? Primarily because flashing is specifically cut to the specifications of your roof. While your new roof's dimensions and cuts might approximate the old roof, the chances of them being exactly the same are slim to none. While the old flashing might work well for a spell, chances are it will not be able to divert 100 percent of the rain from your roof and what you believe you're saving by not replacing the flashing will be spent on replacing portions of the interior of your home, such as the ceiling.

Roof flashing is an absolutely integral part of roofing. Without roof flashing, your roof will become quite susceptible to water damage. Hopefully, throughout the course of this brief guide, you have learned a thing or two about the process of installing roof flashing, as well as its proper use.

inspecting the roof on your home

When was the last time you really looked at your roof? I had no idea how important yearly inspections of my roof was until I found myself footing the bill for a full roof replacement and interior ceiling replacement. Since then, I have learned how to inspect my own roof twice each year. I always inspect it each spring after the harsh winter elements have gone away and again in the fall before winter weather sets in. You can use the information compiled on my website to inspect the roof on your home and make the small repairs that will save you from full roof replacement.
