Introduction
You might be asking the question Is Roof Underlayment Waterproof? Roofing underlayment is an important part of any modern roof. You will not see it, but it is there for a good reason. It is placed right on the roof deck. This layer of protection stands between the roof and water getting inside your house. It keeps out water and helps stop problems like decay and other damage. When there is a lot of rain, snow melting, or even just air moisture, the underlayment makes your roof more water-resistant. It acts like a shield for your roof. This helps the roof stay strong and last longer. It also helps the roofing materials do their job better. If you want to know how it can waterproof your roof, find out more about how picking the right underlayment can give your roof the best performance.
Understanding Roof Underlayment
Roof underlayment is very important to keep homes safe from water, moisture problems, and water resistant issues. Many people do not notice how much it does, but it is a key part of the roofing system. The underlayment sits between the roof deck and the outer roofing materials. It helps protect the roof from weather elements like rain and wind.
You will find different types of roof underlayment, and each works best for special things like stopping moisture, not tearing, or saving money. Some are made of older felt paper, also known as “tar paper,” while others use new synthetic or rubberized asphalt materials. If you are a homeowner planning a new roof, it is good to know how these options work and what they can give you. Each type of roofing underlayment has features made to fight moisture problems and suit your needs.
Definition and Importance
Roofing underlayment is that extra layer of protection you put below shingles or tiles. It serves as a secondary layer of protection and sits right over the roof deck. This is not the main roof you see outside, but it is still very important for durability. The underlayment makes sure water can’t get through easily. So when there is heavy rain or melting snow, this layer helps stop water infiltration. It acts as a strong moisture barrier. Your underlayment will be the first thing to keep out problems from the weather.
This layer of protection is important. It makes your roofing materials stronger. It also gives extra protection to parts of the roof like skylights or along the eaves, which can often get damaged. If you do not have roofing underlayment, then your house can get water damage from excess moisture. Moisture can lead to problems such as mold, rot, and even the slow decay of parts of your roofing.
Roofing underlayment is really needed for places that get lots of ice dams or big storms. Even if you don’t see it, this moisture barrier is a key part for your roofing. It helps shingles work better and last longer. When you pick the best underlayment—this could be synthetic, felt, or rubberized asphalt—you make your roof even stronger. That way, your roof can stand up to bad weather for many years.
Different Types of Roof Underlayment
Roof underlayment comes in three main types. Each type gives your roofing projects some big benefits.
IKO Stormtite® Synthetic Underlayment

Importance in Harsh Climates
Harsh weather can be tough on any roof. There can be ice dams, too much moisture, and fast changes in temperature. These things often cause trouble for people and their homes. Blueskin® underlayments are made for this. They work to keep water out and form a waterproof barrier that can take on heavy rain or lots of ice.
Ice dams make water sit and freeze on the edge of your roof. This usually leads to leaks and other problems because water gets into places it should not. But Blueskin® stops these ice dams, so you do not have leaks or moisture damage. With all the extra moisture from snow melting or rainy days, Blueskin® helps keep the roof deck safe. It keeps away things like rot, mildew, and other troubles caused by too much moisture.
When the weather is extreme, the team at Precision Roofing Canada Inc. picks Blueskin®. The advanced waterproof barrier keeps every roof in good shape for a long time. So, the roof can handle changes in weather year after year and still work well as a waterproof solution.

Roof underlayment should be changed when you do a roof replacement. This usually happens every 20 to 30 years and depends on the things that are used. The weather in Canada can affect how long underlayment will last. That is why it is good to use high-quality underlayment. It helps to make the roof last longer and protects it from tough weather. Good roof underlayment will improve the durability of your roof.
What is roof underlayment and what purpose does it serve?
Roof underlayment is a protective layer installed beneath roofing materials.
