Why Is Metal Roofing Underlayment Important?
Florida’s hot, humid climate and extreme weather conditions play havoc on our homes, with roofs often taking the brunt of the onslaught. Metal roofs are known to be durable, long-lasting, and fire and hail resistant. They are eco-friendly and require less maintenance than other roofing materials.
With proper installation and care, your metal roof can last a lifetime. To get the best outcome from your metal roof, roofing contractors always recommend installing them with metal roofunderlayment.
The Benefits Of Metal Roofing
Modern metal roofing is growing in popularity as it is engineered to be both durable and long-lasting. Some reasons homeowners are considering metal roofing include the following:
- With proper instillation and maintenance, they can last 75 years or longer.
- The metal is class A fire-rated, and very effective at diffusing and deflecting lightning.
- Metal will not crack, warp, or peel, unlike asphalt and wood.
- Metal roofs reflect solar radiation and absorb less heat. This means less interior cooling requirements and thereby saving on energy costs.
Why Should Metal Roofs Have Underlayment?
Underlayment is a water-resistant material that is placed beneath the top roofing layer. Designed to be an extra protective layer against weather impact and water infiltration, it is typically attached to the roof decking or sheathing.
There are numerous benefits to installing a metal roof, including eco-friendliness and longevity. Roofing contractors, however, always advise homeowners to install underlayment with metal roofing for the following benefits:
An Even Surface
Roof decking is seldom flat. Underlayment helps to even out the surface. Metal roofs can be installed over existing roofing materials, so you would need to first install an underlayment for an even surface and ease of installation. This is necessary regardless of whether you are installing the roof directly onto the decking or over the existing old roof.
Waterproofing
Roofing underlayment prevents water infiltration through the roofing materials. Without underlayment, water seepage encourages mold and fungal growth that damages the roof decking and room interiors.
Fastener Protection
Installing underlayment prevents moisture from reaching the decking. If allowed to enter, moisture and condensation will cause the wood to rot and damage the entire roofing structure.
Thermal Protection
Metal roofs can get extremely hot in the Florida summer months. The underlayment acts as a heat barrier, keeping the inside of the home comfortable. Underlayment also acts as a barrier against any drafts.
Noise Barrier
Metal roofs can be very noisy, especially during a storm. Although you may still hear the rain on the roof (which a lot of people find very soothing), the noise of the other elements will be greatly reduced with the installation of underlayment.
Building Code Compliance
To comply with the Florida Building Code, an underlayment must be installed with metal roofs. Some building codes specify the type of underlayment that is required.
Manufacturer’s Warranty
Some roofing material manufacturers may insist on underlayment with the installation of a metal roof. Failing to comply may cause the warranty to become null and void.
Extra Protection In Severe Weather
In the unfortunate event that your roof blows off in extreme weather, the underlayment will still protect the inside of your home from direct exposure to the elements.
