Spray foam roofs are constructed by spraying a liquid material expanding into a foam. This means your roof will have a solid layer of foam across the entire surface. All damaged or saturated areas are removed, replaced with materials as similar as possible, then the top of your entire roof is sprayed. If you have not yet heard of spray foam roofs, this technology was developed during the 1960s for residential, commercial, and industrial use.
Separate containers are used to pump the two chemicals using high-pressure heated hoses directly into a mixing spray gun. Foam roofs are incredibly effective for climates with a lot of sun and heat. Although foam roofs will work well in any climate, Arizona foam roofs can last for more than 50 years when installed and maintained correctly. They can be as durable as tile roofing systems when installed and maintained properly.
Types of Foam Roofs
There are three different types of foam roofs, low-density, medium-density, and high-density. Low-density foam roofs are also referred to as open-cell-foam. Low-density foam is applied to your roof to provide you with an air-sealing barrier and continuous installation. Low-density spray foam is also referred to as one-half pound foam due to an approximate weight of 0.5 pounds for each cubic foot and requires minimal maintenance.
The open-cell structure of the foam application provides you with hardened foam with more flexibility. The application of the two-component spray for your foam is either high or low-pressure. In addition to applying a low-density spray being ideal for foam roofs, it is also used for walls, ceilings, ducts, crawl spaces, and both vented and unvented attics.
Your roof will have an air barrier permeable to both moisture and vapor. Since the cell structure for foam roofs is relatively large, the lower-density foam sprays are more flexible and softer once cured. A low-density foam spray offers you heat insulation while filling in cavities to seal your roof’s joints and cracks from airflow, but you will want to consult your roofing company if you have a solar roofing panels in AZ. Due to the open-cell structure and soft texture, foam roofs will even help with sound absorption.
The application of medium-density foam roofs is either a two-component foam spray or a high-pressure spray. Medium-density foam roofs are ideal for rooftops in Cave Creek due to the hot climate, monsoons, and heavy rains. The type of buildings receiving foam roofs is also an important consideration. Just like with low-density foam roofs, medium-density foam roofs are ideal for unvented attics, filling cavities within your walls, and continuous insulation.
The difference is a closed-cell foam spray is used for the installation of medium-density foam roofs. This type of roof is common when a high R-value insulation is necessary for every possible inch. Medium-density foam roofs act as a barrier for water, and as a result, push more water down into your gutter systems. It can also be a barrier for vapor, and air while decreasing noise levels. This density provides you with both a high bond and tensile strength.
A medium-density roof offers low vapor permanence not impacted by rain driven by high winds or moisture, which is something that residential roofs in Goodyear experience on occasion during monsoon season. . Your final option is a high-density foam roof. This is important for both increased strength and high levels of insulation. This type of roof provides you with a much denser structure than either low or medium-density foam roofs. High-density foam roofs are a good option for exterior insulation or your roof due to the seamless and rigid nature.
The foam spray applied for high-density foam roofs is ideal for significantly decreasing your energy bills over the lifetime of your roof. This is because of the thermal resistance. High-density foam roofs provide you with protection from infiltration by water and air. Your application will even strengthen the structure of your roof. Spray foam roofs in Scottsdale can increase your home’s resistance to wind uplift resulting in less damage during high Arizona winds.
Foam Roofing Benefits
Once the liquid compounds for foam roofs are mixed, the reaction during your application is extremely fast. The foam expands immediately on contact, creating the formation of a bond, providing you with a barrier to vapor, sealing gaps, and offering extra insulation. Spray foam is so versatile that it will seal your exterior walls, interior cavities on inner walls, little cracks, crevices, attics, and crawlspaces, and support the efforts of your interior spray foam insulation when it comes to heating and cooling the home.
Both air movement and filtration are limited throughout your entire home by foam roofs. This will make your home a lot more comfortable by decreasing allergens and pollutants in addition to lowering your energy usage.
The additional benefits of foam roofs include:
• Proven effective since the 1960s
• Fast installation
• Easy to maintain
• High R-value
• Often last more than 50 years
Foam Roofing Disadvantages
Spray foam roofs only have two disadvantages. First, the right weather conditions must be present during the installation. This will decrease your available opportunities for installation. A good example is if you have heavy rainfall the night prior to your installation, you will need to reschedule. Typically not an issue for rooftops in AZ! The foam roof will not stick if any moisture is present on your roof at the time of application.
The second disadvantage is a spray substance is required for the application of foam roofs. This means there is a possibility some of the substance can be caught by the wind. When this occurs, cars and surrounding buildings can be affected, even other roof surfaces. No worries though, because we take precautions to cover cars to protect your property, and we also repair roofs in Phoenix if damaged by our projects.
Average Cost of Spray Foam Roof Installation In AZ
The cost in Arizona for a typical spray foam roof for a 1200 square-foot home is approximately $6,000. The cost for a commercial or industrial roof for a 10,000 square-foot building is roughly $55,000. The average cost per square foot for commercial, industrial and residential buildings is about $5.50.
