So, you’ve come to the point where you need a new roof and are looking for alternatives. Perhaps repairing leaks after a leak is becoming a rather annoying part of your project description.
Should you continue the short-term gain of fixing leaks, or should you invest in a cheaper, long-term option?
The very first thing I have for you is, how long before you retire?
The next question I have for you is, how receptive are you to change?
Change is hard. I just got a note from my credit card company that my cable bill went up to $50. Looking into it, after two years of loyal service (and ending my new customer pricing), I was now handed a higher monthly invoice.
Most individuals are lazy and simply accept spending more. I wanted to open my horizons to change, introducing me to the world of online streaming services.
Upon study, I can cut the cord and bring a monthly cable and internet bill down from $202/mo down to $120/mo!
I just had to be open to change and give it an opportunity.
The same can be stated for spray polyurethane foam roof systems. Most individuals wouldn’t be amenable to change and install the same roofing system they’ve had on for years.
However, for anyone to change, the apparent benefits need to be there.
But for anyone to change, the clear benefits need to be there.
Let’s get into it…
A quick definition of what SPF is
Spray Polyurethane Foam (SPF) for roofing applications is manufactured on the Jobsite by mixing two highly reactive chemicals.
The chemicals, A & B, are pumped from separate containers through heated, high-pressure hoses into an inner mixing spray gun.
Polyurethane was initially used for roofs in the early 1960s.
Many changes have occurred in the equipment and chemistry of polyurethane roofing in the previous fifty decades, resulting in today’s dependable roofing applications.
HERE ARE THE 7 PRIMARY Benefits OF A SPRAY POLYURETHANE FOAM ROOFING SYSTEM
- Top R-value
- Instantly installed
- Easy to maintain
- Proven since the 1960s
- Spray foam roofs have a high R-value
Spray polyurethane foam has the highest R-value of any commonly used roof insulation.
Here are the average R-values for some frequent roof materials
- Spray Polyurethane Foam: 6.6 percent inch
- BUR Smooth: 0.24 percent inch
- Metal: 0.00 per inch
- BUR Smooth: 0.24 per inch
- XPS Insulation: 5.0 per inch
- Polyiso: 5.5 per inch
R-value is the ability of an insulating substance to withstand heat flow. The higher the R-value, the greater the insulating power.
The higher the R-value, the less heat or cool air that will pass through. Higher R-value = less HVAC usage = lower energy costs
The total payback of your roof typically occurs in under ten years through savings in heating and cooling expenses.
- Spray foam roofs are renewable
One of the benefits of a polyurethane roof is its capability to be re-coated.
A correctly installed and maintained spray polyurethane foam roof should not require re-coating for 10 to 20 decades. The ideal way to determine when a spray roofing foam needs to be re-coated is to measure the remaining coating thickness onto the roofing and recoat before the coat is too thin to supply U.V. protection.
The first application of the coating is usually applied at a thickness of 20-30 mils.
After 10 years, the coating could be decreased to a thickness of 7-10 mils, depending upon the wear of the roof.
Many coating manufacturers offer extended warranties with each re-coat. This choice, along with scheduled maintenance, allows a spray foam roof to be a sustainable roof system.
- Spray polyurethane foam roofs are quickly installed
Spray foam roofs are set up quicker than other roof systems, due to:
- Many SPF roofing projects involve little to no tear away
- Spray foam roofs are spray-applied, meaning that they could go around penetrations effortlessly
- Spray foam roofs require less equipment and material than traditional roofing systems
Because spray foam is quickly set up, business interruption and labor costs are minimized.
- Spray polyurethane foam roofs are self-flashing
Self-flashing describes spray foams’ capability to conform to irregular shapes.
Other roofing systems, such as rubber, will need to be custom cut to be able to be set up correctly around a curb.
Self-flashing enables spray foam to be implemented faster around all penetrations, including:
- Parapet walls
- HVAC units
- Spray polyurethane foam is seamless
A big advantage spray polyurethane foam has over other roofing systems is that it’s seamless.
Becoming seamless, and therefore monolithic and watertight, avoids conventional single-ply membrane seams that tend to be the sources of leaks.
Seam separation of a rubber roof. An invitation for water penetration that will give rise to a roof leak.
How do flows from on a rubber roof?
Seams begin to separate over time and permit water to get inside. Furthermore, they can allow some water to get in, it freezes, and once it thaws out, it breaks apart the seam much more.
Wind uplift is also an issue with seams. Wind will finally get under a marginally separated seam, loosen, and ultimately allow an opportunity for water to enter the building.
- Spray polyurethane foam roofs are simple to maintain
Perhaps a sharp instrument has been dropped or the HVAC guy planted the HVAC panels in your roof like a javelin.
To be able to fix these minor fixes, all you will need is a utility knife and a few caulk.
Step 1: cut out the defective area
Step 2: dry out the area
Step 3: Apply caulk and smooth
That’s it. Minor repairs could be done by in-house maintenance staff.
Here we’ll take time at the end of the project to show you how easy it is to repair a small incision.
- Spray polyurethane foam is proven to be beneficial
Since the early 1960s, spray polyurethane foam roofs have been set up and recoated, strengthening the favorite phrase “A spray foam roof is the last roof you will ever have to put in”.
Several roofs that have been installed decades ago are going in their 2nd or even 3rd recoat.
Conclusion on spray foam advantages
Polyurethane roofs are set up immediately, resulting in a lower labor cost and less disturbance. When thinking about the numerous variables in a re-roofing undertaking, the versatility of a polyurethane roof makes it a plausible and cost-effective alternative.
