It’s said that a roof is only as strong as its weakest link. This may very well be true, but what’s even more important is the layer of protection that sits underneath the metal roofing – the roof underlayment. Roof underlayment is key in protecting your home from water infiltration, and it’s a layer that should not be overlooked. Many homeowners here in Texas don’t realize the importance of this vital component until it’s too late. The bright side is that a few different types of underlayment can be used with metal roofing, so you have some options. That’s exactly what Tiger Roofing LLC’s agenda for today is; we will discuss the different types of underlayment and what each one is best suited for. We will also help you decide which type of underlayment is right for your home. So, if you’re darting to install a metal roof shortly, keep reading!
Roof Underlayment: An Overview
Selecting the right underlayment products is crucial for ensuring that your standing metal roof system performs at its best for the lifespan of the building. There are several things to consider in designing a roofing system, including making sure that there are four elements: a water barrier, thermal insulation, vapor retarder, and air barrier. The location of these will depend on the climate where the building is located.
Suppose you do not select the right roof underlayment. In that case, your roof may leak or retain moisture because of vapor diffusion or air exfiltration. This could cause hidden components to start deteriorating faster and shorten their lifespan, which would require repairs eventually. To ensure your underlayment lasts as long as possible, choose one whose intended service life closely matches that of the metal roofing system it will use.
What Types of Underlayment Are Available in The Market?
Well, there are three different types of roofing underlayment available in the market, which are as follows:
1. Asphalt-Saturated Felt:
It is made of a base material saturated with asphalt. It is then covered on both sides with asphalt-impregnated fiberglass mats.
2. Rubberized Asphalt:
It is a synthetic rubber compound reinforced with fiberglass mats or polyester fabric and then coated with asphalt.
3. Non-Bitumen Synthetic:
It is made from polypropylene, ethylene propylene diene monomer (EPDM), high-density polyethylene (HDPE), or modified bitumen. This type of underlayment is usually white in color. It does not require the utilization of any organic solvents during installation.
Each type has advantages and disadvantages, which you should consider before purchasing.
Metal Roof Underlayment Benefits for Homeowners in Terrell
Of course, many benefits come with installing metal roof underlayment. Here are just a few of the most notable advantages:
1. Enhanced Protection:
As previously mentioned, one of the main functions of underlayment is to protect the roof deck from water damage. By installing a high-quality underlayment, you can be sure that your roof will be well-protected against any moisture that may try to penetrate through the metal panels.
2. Improved Energy Efficiency:
In addition to protecting your home from water damage, metal roof underlayment can also help to improve energy efficiency. By reflecting heat away from the roof deck, an underlayment can help to keep your home cooler during the summer months. This can lead to lower energy bills and a more comfortable home.
3. Enhanced Durability:
Metal roofs are durable, but the addition of underlayment can make them even more resistant to wear and tear. By protecting the roof deck from the elements, an underlayment can prolong the life of your metal roof and keep it looking new for longer.
4. Increased Safety:
In some cases, metal roofs can be slippery, posing a hazard to people walking on them. However, by installing an underlayment, you can add a layer of traction that will help to prevent slips and falls. This is especially vital if you have young children or elderly family members who may be at risk of falling.
5. Better Insulation:
In addition to protecting your roof deck, an underlayment can also help to insulate your home. This is especially vital in areas where extreme temperatures are common. By keeping your home better insulated, you can reduce energy bills and make your home more comfortable year-round.
The Best Underlayment for Metal Roofs
Although felt and synthetic underlayment works well for asphalt roofs, a metal roof needs something different to prevent wear and tear. The constant expanding and contracting during thermal expansion will ruin the integrity of regular types of underlayment. However, the ice and water shield are designed to handle the metal panels going back and forth without issue.
While metal roofing needs high heat ice and water shield as underlayment, it’s also used with premium roof systems (slate and cedar shake) to add extra protection. High-heat ice and water shields have cotton-like fibers that won’t stick to the metal panels as they expand and contract, which prevents the underlayment from being destroyed. Water finding its way in will not damage your decking if you use this product.
Why should the Roof Underlayment Process Be Left to Roof Experts?
Roofing experts understand that the roof is the most important part of any building. It is the first line of defense against harsh weather conditions, so you must install it correctly. Underlayment is one of the most complex aspects of a roof installation. Going DIY on your roofing project is never a good idea. It is likely to void any warranties that come with the materials. It is always best to leave the roof underlayment process to the professionals.
