When it comes to protecting your roof from water damage, two popular options to consider are ice and water shield, and metal valleys. Both roofing materials are designed to prevent leaks and lengthen the life of your roof. However, choosing between the two can be a difficult decision, especially if you are not familiar with the HVAC industry. In this blog, we will discuss the key highlights of the ice and water shield and metal valleys. These key points include the installation process, survival and maintenance, cost analysis, climate considerations, common misconceptions, and of course some real-life application stories. By the end of this blog, you will have a better understanding of which option is best for your personal roofing needs.
Understanding Ice & Water Shield
Before diving into the details, it's important to understand what exactly ice and water shield is. This product is a waterproof membrane specifically designed to protect vulnerable areas of roof decking from moisture damage. It is typically sold in rolls with a self-adhesive backing, making it easy to install. This material is commonly used in roof valleys, drip edges, and anywhere additional protection is needed, including the gutter. It acts as an underlayment that prevents damage to the roof decking, extending the life of the roof when properly installed under shingles or metal roofs.
Science Behind Ice & Water Shield Protection or Felt
The science behind ice and water shield lies in its construction. Unlike traditional roofing felt, which is a felt type commonly used as underlayment, this product is a self-adhesive material that adheres directly to the roof surface. This creates a watertight bond and prevents water from infiltrating the roof decking. The rubberized nature of ice and water shield makes it not only water-resistant but also highly pliable, allowing it to conform to the contours of the roof decking. This flexibility ensures that the material remains effective even in extreme weather conditions, where the commonly used felt may fail. By creating a barrier between the surface of a roof and potential water related damage, such as ice dams or heavy rain, the ice and water shield provides added protection. The additional peace of mind against tar and other damaging elements makes this product a crucial component to protect premium roof systems like slate and cedar shake, making it a better option than felt would be in many cases.
Benefits of Using Ice & Water Shield for Roofing in Valleys or Metal
- Prevents water infiltration in vulnerable areas such as roof valleys, extending the life of the roofs material.
- Acts as an additional layer of protection, reducing the risk of leaks and water related damage.
- Self-adhesive backing ensures a watertight bond, creating a barrier to prevent water from seeping into the roof deck.
- Provides added protection against ice dams and heavy rain, common causes of water related damage in roof valleys.
Exploring Metal Valleys
In addition to ice and water shield, another option to consider for your roof valleys is metal valleys. Metal valleys, also known as valley flashings, are made of durable metal materials such as galvanized or aluminum. They are designed to direct water off of the roof and from vulnerable areas. Metal valleys are an attractive option for homeowners looking for long-lasting and visually appealing solution. They offer durability and are capable of withstanding extreme weather, making them a favored choice for a variety of roofing projects, especially those using materials such as cement or tile.
Metal Valley Types: Open vs. Closed
When considering metal valleys for your roof, it's important to understand the two main types: open valley and closed valley. An open valley is the most common type of metal valley and is made with shingles or tiles but not a metal sheet. An open valley allows water to pass through the gap between the two sides of the valley. On the other hand, a closed valley uses a metal sheet as the valley flashing, which prevents water from passing through. The choice between open and closed valley depends on factors such as aesthetics and the specific requirements of your roofing project.
Advantages of Installing Metal Valleys on Your Roof
- Metal valleys are highly durable and can withstand extreme weather conditions, making them a long-lasting solution for your roof.
- They provide an aesthetically pleasing finish to your roof, adding a touch of elegance to your home.

It is also recommended to install a layer of underlayment over the ice and water shield for additional protection. This installation process should be carried out by a professional to ensure proper sealing and effectiveness of the ice and water shield.
Step-by-Step Guide to Installing Metal Valleys
Installing metal valleys requires careful attention to detail to ensure proper waterproofing and protection. Here is a step-by-step guide to installing metal valleys:
- Remove any existing valley material and clean the area.
- Measure the length of the valley and cut the metal flashing to fit.
- Install metal flashing by securing it to the roof deck, ensuring a tight fit and proper alignment.
- Use roofing screws or nails to secure metal flashing in place, ensuring a watertight bond.

DIY vs. Professional Roof Repairs: Making the Right Choice
Key Highlights Different climates demand specific roofing materials for optimal performance. Consider factors like temperature variations, moisture levels, and wind exposure. Hot climates benefit from reflective materials like metal or clay tiles. Cold regions require durable options like metal, slate, or impact-resistant shingles. Coastal areas need corrosion-resistant materials like metal or treated wood. Introduction Choosing the right roofing materials is very important for protecting your home. Many homeowners do not realize how much climate affects a roof's lifespan and how well it works, especially during roof installation. Knowing how different roofing materials perform in different weather conditions can help you avoid expensive roof repairs and early replacements. It may also prevent damage inside your home. This guide on roofing options that suit your climate will help you make a smart and lasting choice for your home. Understanding Impact of Climate on Roofing Products & Materials Climate has a strong effect on how long your roof lasts and how well it works. Big changes in temperature, heavy rain, strong winds, and salt from the coast all cause damage over time. It is important to choose roofing materials that can handle these problems. This way, your roof will stay strong and protect your home for many years. If you do not pay attention to weather factors, the impact of climate on roofing products can cause many issues. You might end up with cracked or curled shingles, water leaks, mold growth, and even higher energy costs. By deciding to use materials that match your local climate, you can protect your home better and save on heating and cooling costs. Temperature Variations on Material Durability Temperature changes, especially big shifts from hot to cold, can greatly affect how long roofing systems last. Additionally, heavy winds can cause materials to change size with these temperature changes. This can cause stress and may lead to damage over time. For example, in areas that have hot summers and freezing winters, materials that can't handle this constant change might crack, twist, or get weak. It is essential for roofing materials to have a certain resistance to temperature changes. If they break down from the stress of temperature, they may not do a great job of keeping the roof secure, making it more likely to cause leaks and water damage. When choosing materials for your roof, it’s important to choose ones that fit your local climate. For places with large temperature changes, select materials that are flexible and can deal with thermal stress well. Metal roofs are one such option, famous for managing greater temperature changes without losing its strength. This could be an option somewhere like Texas, since we see that Fort Worth roofing alone is quite diverse. Moisture and Rainfall Effects on Roofing Options Regions with a lot of rain and humidity can create special problems for roofing materials, especially if proper drainage systems like gutters are not installed. When roofs stay wet, they can collect mold, mildew, and rot. This situation could lead to expensive roof repairs or even damage to the structure. It is important to choose materials that do not soak up moisture in these areas, which include metal, tile roofs (such as clay or concrete), and asphalt shingles treated with copper that resist algae. These materials are great at guiding water away and reducing the chance of water damage. In addition to selecting the right materials, proper roof ventilation is key in preventing moisture buildup in the attic space. Proper ventilation allows air to move freely, reducing the chance of condensation and moisture-related issues, including mold.
