1. Limited Installation Window

SPF Roofing is a spray installation, this application technique means that the SPF needs to be installed in specific weather conditions. The best weather conditions are warm and dry with minimal wind.

This means that you are at the mercy of Mother Nature to get your roof repaired or installed.

Solution: Contact your contractor before your area’s roofing season, that way you can schedule your installation early, and you have plenty of time to reschedule if the weather changes.


2. Finding the Right Contractor

As foam roofing gains popularity with commercial property, you want to make sure you find a reputable contractor. Unlike traditional roofing, installing an SPF roof requires knowledge of the chemicals and application techniques. Installation requires a high degree of technical expertise and experience.

Solution: Check to see if your potential contractors are certified and take part in industry organizations. The Spray Polyurethane Foam Alliance (SPFA) has an ISO-17024 compliant certification program that has multiple levels, requires the contractor to pass an exam and meet the criteria for a certification. You can find a database of certified contractors online.


3. Overspray Potential

The spray application of SPF roofing means that the wind could carry to spray onto cars and other surfaces. While this does not pose a health concern, it is a concern for surrounding property.

Solution: There are multiple ways to prevent this from happening. Have a discussion with your contractor to ensure that they utilize industry best practices to prevent overspray. If it does happen, your contractor should cover cleanup costs.


4. Upfront Costs

For an average 20,000 sq. foot commercial roof, it will usually cost between $4.00 and $7.00 per square foot in materials and labor to install a typical SPF roofing system. Compared to other flat roofing systems, this upfront cost can be higher.

Solution: An SPF roof pays for itself quickly with energy savings and longevity of the roof. You can work with your contractor to calculate potential energy savings to make sure you installed the right thickness of SPF.


5. Maintenance

SPF roofing systems should be regularly inspected whether there is known damage or not–especially after severe weather events that could cause damage, such as hail storms, tornadoes, and hurricanes. Punctures and damage should be caught early to prevent leaking into the facility.

Solution: Most contractors have maintenance plans and warranties to keep your roofing system in decent shape. West Roofing System’s M.a.R.S. Program offers multiple packages to fit your needs.


6. Punctures

Spray foam roofing does not have as high of a resistance to punctures or damage. An SPF roof has a top layer of silicone; in the event of severe weather, there is a chance for the roof to suffer from a puncture. Usually, this kind of damage can be found with regular inspections before leaking occurs.

Solution: You can contact your contractor for a repair. The repair needs to be made with silicone because conventional roofing repair materials do not adhere to the silicone coating. It’s best to keep up your roof warranty so that it will be covered.


7. Expired Warranty

When you install a new roofing system, it’s best to purchase a warranty. Most manufacturer warranties require the contractor to perform repairs for the first few years after the install.

Solution: With SPF roofing, you can renew your warranty by restoring your roof with a new coat of silicone.


No roofing system is immune to needing repairs, that’s why it’s important to keep up your warranty and work with contractors that you trust. Spray Polyurethane Foam Roofing Systems are becoming the go-to roofing for commercial, industrial, and manufacturing facilities that are looking for a sustainable, economically efficient option.

At West Roofing Systems, our goal is to get you a long-lasting, durable roof that will protect your facility. That includes working with our award-winning team to choose the best roofing systems to meet your needs.
