Pros and Cons of Roofing Systems with Spray Polyurethane Foam (SPF)

Posted on June 27th, 2018 by Applied Roofing Services

Spray polyurethane foam roofing or (SPF) is a roofing system that is designed to offer the best in both weather protection and sustainability. An SPF roofing system has negligible drawbacks when compared to its utility and it is usually favorable for use on most types of buildings. It provides long-lasting results with minimal maintenance or repairs.

Pros of SPF Roofing

Spray foam roofing has many benefits that makes it a viable alternative to other roofing methods. A few benefits of SPF roofing to homeowners include:

  • Easy to Install – Professional SPF roofing involves easy and quick application of the foam and coating.

  • Control Potential Leaks – All the seams and grooves are sealed by the application of liquid SPF mixture to reduce the possibility of leaks.

  • Energy Efficient Alternative – Lower the energy cost during every season and help to maintain the internal temperatures of the building.

  • Easy to Maintain – Requires very minimal upkeep after installation and can prove to be a longstanding option with correct maintenance and semi-annual inspections.

  • Allows Waterproof Roofing – Polyurethane foam allows for leveling out the roof to reduce the possibility of damage due to water accumulation.

  • Offers Sustainable Roofing – SPF roofs are renewable and cost-effective as they produce no waste when the foam is re-applied because their application involves negligible stripping of old roofing.

  • Environmentally Friendly Option – Being free from ozone-depleting CFCs (Chlorofluorocarbons) and producing minimal VOC’s (Volatile Organic Compounds), SPF is environment-friendly.

Cons of SPF Roofing

Spray foam roofing also has its drawbacks. If you have questions, you should always bring them up to your contractor to make sure you still have the most accurate information possible. Drawbacks can include:

  • Chances of Overspray – The potential to overspray an area or the spray being carried by the wind onto other surfaces is always there.

  • Requires Annual Maintenance – SPF roofs must be inspected at least twice a year even if there is no apparent damage.

  • Needs Accurate Repairs – SPF roofs are extremely vulnerable to puncture and other types of damage; only certain types of materials can be used to make necessary repairs.

  • Has Limited Installation Window – Installation is determined by the weather, and extreme temperatures and moisture need to be avoided.

While weather and wind seem to be the determining factors when it comes to the drawbacks of SPF roofing, they are minimal when compared to the benefits.

SPF roofing offers distinct advantages over other roofing materials. Before you make a decision, however, make sure to talk to your roofing contractor to find out if it is a feasible option for your building. For many, it’s an investment that will pay itself off in both time and money.

Insulation Basics of Spray Foam Roofing You Should Know

Posted on September 14th, 2016 by Applied Roofing Services

Spray polyurethane foam is one of the most popular forms of insulation when it comes to roofing and protecting one’s home from the elements. It is easily applied, sets up quickly and will remain in place for long periods of time without deteriorating or breaking down.

Spray Foam Roofing

How Spray Foam Works
Spray foam is produced by blending two chemicals and then forcing the mixture through a heated hose directly onto the surface where the insulation is to be applied. The chemical reaction creates a liquid that is turned into expanding foam when it comes in contact with heat. As it passes through the hose, the foam expands and spreads out to cover the surface of the area to be protected.

Two Types of Spray Foam
There are two primary types of spray foam. The first type is extremely light and does not cover as much surface as stronger types of foam. This is known as open-cell foam. Closed-cell foam is dense, spreads more thoroughly and is much stronger than open-cell foam. This type of foam is more rigid and extremely durable. It is also more expensive.

Protects Against Interior Damage
Spray foam roofing and insulation is capable of controlling even the smallest of leaks. If the foam is applied correctly, it will prevent water, debris and wind from working its way through to the interior of the home. As the foam expands, it creates a protective coating that effectively seals any creases or weakened areas that may be present.

Spray foam roofing and insulation is effective at protecting both the interior and exterior of the home if it is applied correctly. While many people may want to do it themselves, hiring a professional is always the best option when dealing with strong chemicals.

7 Spray Foam Roofing Myths Debunked

Posted on August 31st, 2016 by Applied Roofing Services

Spray foam roofing has been around for years and is used primarily on flat-topped buildings, mobile homes and commercial buildings. It offers many benefits, and still holds less value in the residential world. The problem is that many homeowners disregard it as an effective choice because of the many myths that revolve around its use.

Foam Roofing in Los Angeles

Here’s the truth behind these common spray foam roofing myths:

  1. Spray Foam Is Toxic
    Spray foam roofing is far from toxic. It is manufactured from inert substances and does not contain any harmful chemicals or toxins.

  2. Not as Durable as Other Forms of Roofing
    Foam roofing is extremely durable. It contains the same type of polyurethane that the soles of many types of work boots are made of. Once it sets, it is extremely hard and will not chip or crack.

  3. Birds Will Destroy It
    While birds may attempt to peck at uncovered areas of roofing, they won’t peck at a roof that has been freshly sprayed. The surface is too hard and they cannot break through the outer coating.

  4. Similar to Memory Foam Mattress Material
    Memory foam mattresses are made from soft, cushiony foam, whereas spray foam roofing is not soft, nor does it have cushion to it. Once it sets, it is becomes stiff and rigid and will not give or bend with weight.

  5. Foam Boards Insulate Better
    Foam boards do not insulate better than spray foam roofing. Spray foam fills in gaps and creases, providing a firm, water and air tight seal.

  6. Sucks Up Water
    Spray foam does not soak up water. It is made from durable polyurethane which causes water to flow over its surface not saturate it.

  7. Not Sturdy Enough to Walk On
    Spray foam creates a firm covering over any surface. Once the foam cures, it can be easily walked on without fear of damaging the surface.

A roof is the most important part of any residential or commercial property. With a proper roofing system and drainage on your roof, you can ensure the longevity of your roof as well as your home.

The Versatile Benefits of Spray Foam Roofing

Posted on February 18th, 2016 by Applied Roofing Services

Spray foam roofing is an ideal solution for many roof repairs. Not only is it cost effective and extremely convenient, it has a host of other benefits that will save you both time and money. Homeowners that opt for spray foam roofing Los Angeles can actually extend the life of their roof and protect their home from water damage. Let’s have a close look at some of the versatile benefits of spray foam roofing.

Flexibility
Spray foam roofing is flexible enough to withstand the contraction and expansion of a roof at normal levels. It can also withstand the stress associated with high winds and turbulent storms.

Versatile
Polyurethane spray foam roofing can be used on any existing roofing material. It also conforms to peaks, valleys and crevices and creates a seal that flows along the lines of the roof. It can be used on new roofs and existing roofs that need minor repairs or renovations.

Reduces Ponding
Because it creates a smooth surface and fills in gaps and low areas, spray foam roofing reduces ponding and prevents water from accumulating. The foam also fills in deep lines or tracks and prevents water from penetrating deep into the roof.

Self-Flashing
Spray foam roofing easily conforms to whichever surface it is applied to. It can be used around chimneys, HVAC units, skylights and vents to create a tight seal that prevents leaking and internal water damage.

Seamless
When spray foam roofing is applied, there are no seams to worry about. The foam sticks together in one solid sheet, with no cracks, lines or seams that would allow moisture or air to penetrate into the roof.

Prevents Leaks
Spray foam roofing creates a seal that is both water resistant and air tight. The foam prevents water from seeping in and also keeps warm/cool air from leaking out.

Remember, it is very important to hire an expert roofing company in Los Angeles for spray foam roofing. Contact Applied Roofing Services at (213) 255-3677 for professional roof installation services at affordable prices.

Energy Efficiency Roof

Posted on March 18th, 2015 by Applied Roofing Services

As a roofing expert, I have seen and used all the different roofing systems that are available. I do this according to what clients want and to their budget. However, of all the roofing system alternatives, there is one that is always my topmost recommendation: spray polyurethane foam.

Spray polyurethane foam, commonly called SPF in the industry, has been used for roofing and insulation for almost 50 years. Foam roofing systems have stood the test of time and have been proven to be durable, reliable and very affordable. Building owners who have made this choice as well as independent studies have established this beyond a shadow of doubt. As long as they are well maintained, foam roofing systems can last indefinitely.

The greatest advantage of SPF, though, is its energy efficiency. It facilitates energy savings of about 30% or more compared with other roofing systems. The cost of putting up an SPF roof pays for itself in less than 5 years through energy savings alone. The foam has an R-value of 7.14 per inch of thickness. This enables it to provide higher thermal resistance with less material than every other kind of roofing insulation. This is thanks to SPF’s superior insulation properties.

Spray polyurethane foam is a mixture of two components: polyol and isocynate. The two are pushed into a proportioner, which heats them and then pumps them into a spray gun. Here, they are mixed and then sprayed onto a roof in liquid form so they form one continuous layer that is seamless, solid and stable.

For proper application, SPF should go onto a clean surface. There should be no contaminants, such as oil or dust, or else it will not adhere to the surface as it should. It should also be applied in accordance with local building codes. After application, a protective elastomeric top coat is added. Typically, this coat is applied as a spray as well.

Apart from excellent energy efficiency, foam roofing has a number of advantages over conventional roofing methods because of the following qualities.

  • Flexible
    The foam can be sprayed onto virtually every kind of surface. This eliminates problems with roofs that are irregularly shaped and those that have protrusions.
  • Seamless
    Polyurethane foam is applied in liquid form so it becomes a single, monolithic layer covering the whole roof. There are no joints and no seams, which are where most leaks in traditional roofs come from.
  • Lightweight
    Foam roofing weighs about 50 pounds per square. Compare this 800 pounds, which is what a built-up roof weighs, and the 100 pounds that goes into single-ply roofs with ballast.
  • Thermal insulation
    SPF has superior insulating properties to those of other roofing options available for commercial buildings.
  • Sustainable
    Foamed roofs are very undemanding when it comes to maintenance. There is very little waste in putting one up, and their lifespan is indefinite.
  • Waterproof
    SPF is excellent for various waterproofing applications. It makes a roof completely impenetrable to water. SPF is made up of a billion closed cells which act as a highly efficient air barrier that ensures that moisture cannot infiltrate a building. This minimizes problems with dew, which if left unchecked can lead to water condensation inside a building; this is how mold and mildew form. Moisture infiltration is a leading cause of building deterioration.

Should the uppermost layer of a foam roofing system get damaged, it will still not leak because of the underlying foam. This is evidenced by the incident where the Superdome in New Orleans was damaged in a severe hailstorm, which left numerous hairline cracks on the top coat. However, there were no leaks even though the roof went without being repaired for more than 10 years. If water had penetrated through all the layers of foam, it would have been isolated only to the part where the membrane was penetrated. It is easy to repair minimal penetrations using elastomeric caulk, which will restore the structural integrity of the system.

The problem of water ponding is quite common with other roofing systems. When re-roofing with SPF, it is very easy to add thickness while spraying to ensure that water will drain off the roof properly. This also takes care of the problems of an increased weight load caused by water accumulation.

Other Applications

Apart from roofing, I use SPF for insulation and protection for a number of other structures. I use it to insulate tanks, freezers and other structures in the wine industry, oil industry and chemical processing plants. It has yet to fail me as a roofing system or as an insulator in these structures.
