Imagine your roof as a shield, protecting your home from the elements. Now, picture roofing felt like the armor that reinforces that shield. This essential material enhances the durability of your roof, providing an extra layer of protection against water damage. 


But
roofing felt does more than just waterproof your roof. It also adds insulation, keeping your home comfortable and energy-efficient. 


In this article, we'll delve into the various uses and benefits of roofing felt.

The Importance of Roofing Felt in Waterproofing

You should understand the importance of roofing felt in waterproofing your home. When it comes to protecting your home from leaks and water damage, using roofing felt under metal roofs installed by skilled roofers offers several benefits. 


Firstly, roofing felt acts as a barrier between the metal roof and the
underlying structure, preventing moisture from seeping through and causing damage. It provides an extra layer of protection against rain, snow, and other elements. 


Additionally, roofing felt helps to minimize condensation, which can lead to mold and rot if left unchecke
d.


Types of Roofing Felt

There are different types of roofing felt materials available, each with its own advantages. 


For example, asphalt felt is a popular choice due to its durability and resistance to UV rays. 


Synthetic felt, on the other hand, is lightweight and offers excellent tear resistance. 


Different materials like rubberized asphalt and fiberglass provide superior waterproofing capabilities. 


Each material has its own unique properties and benefits, so it is crucial to choose the right one based on factors such as climate, budget, and personal preferences.


How Roofing Felt Provides Extra Insulation for Your Home

Roofing felt acts as a barrier and provides extra insulation, keeping your home warmer during the winter months


This additional insulation reduces heat loss, resulting in energy efficiency benefits and cost savings. 


When properly installed under your roofing materials, roofing felt helps to prevent air leakage and moisture infiltration, which can lead to heat loss and structural damage. 


By creating a thermal barrier, roofing felt helps to maintain a consistent temperature in your home, reducing the need for excessive heating and subsequently lowering energy costs. 


Additionally, the use of roofing felt prolongs the lifespan of your roof by protecting it from the elements, ultimately saving you money on potential repairs or replacements. 


So, by using roofing f
elt for insulation, you not only enhance your home's energy efficiency but also enjoy long-term cost savings.


Choosing Between 15 lb and 30 lb Roofing Felt

When it comes to choosing between 15 lb and 30 lb roofing felt, the difference lies in thickness and durability.


15 lb Roofing Felt:


  • Lightweight: As the name suggests, it weighs 15 pounds per 100 square feet.
  • Suitable for standard roofing projects: It offers basic protection against moisture and acts as a vapor barrier.
  • Economical: 15 lb felt is more budget-friendly compared to the heavier options.


It is ideal for warm climates and low-slope roofs where heavy rainfall is less common.



30 lb Roofing Felt:


  • Heavier and thicker: Weighing 30 pounds per 100 square feet, it provides enhanced durability and protection.
  • Superior moisture resistance: Offers better defense against water infiltration, making it suitable for areas with heavy rainfall or extreme weather conditions.
  • Recommended for steeper roofs: Its added weight and thickness make it ideal for roofs with higher slopes.
  • Increased cost: 30 lb felt is typically pricier than its lighter counterpart but offers greater longevity.


The choice between 15 lb and 30 lb roofing felt depends on your specific roofing needs, climate, and budget considerations. 


While 15 lb felt is suitable for many situations, 30 lb felt offers extra peace of mind in areas prone to severe weather or for roofs with steeper angles.
