Before deciding which company to hire to install your SPF roofing system there are certain matters you need to be aware of.

Choose a Qualified and Experienced Contractor

To install SPF roofing systems, even large ones, you will not need to hire a big crew but the individuals you do hire need to have a high degree of technical knowledge and substantial experience. The applicators must be extremely precise and understand how to use the chemicals involved in the spraying process. Who you hire, therefore, is of vital importance since if your SPF roofing system is not installed correctly, it will not provide you with all the great benefits you may have expected. A typical sign that it hasn’t been installed properly is usually interlaminar blistering of the SPF layers. These foam blisters develop because it was applied under unsuitable weather conditions or due to improper substrate preparation, or even due to equipment issues.

Must Consider the Weather

At Armstrong, we always ensure that we install your SPF roofing system under ideal weather conditions. We never apply SPF when the substrate temperature is below the manufacturer’s recommendations or when the humidity is within 5 degrees of dew point. What’s more, it should never be applied when there is ice, frost, surface moisture, or visible dampness present on the surface to be covered. Furthermore, on windy days, it may be necessary to apply barriers to preserve the foam quality and avoid overspray issues. We always apply your SPF roofing system on warm and dry days with no wind. By doing so, we provide our customers with all the benefits of an SPF roofing system and avoid interlaminar blistering in the foam and the possibility that the foam won’t adhere correctly to the substrate because of surface moisture.

Protect Against Overspraying

SPF is very lightweight so when it is sprayed caution must be exercised to avoid overspraying outside the area of application. The overspray does not pose a health hazard, but it can stick to many of the surfaces it makes contact. Consequently, the applicators should have overspray protection before starting the actual spraying process. Even a sudden slight breeze can carry the overspray to nearby structures, where it can be extremely difficult and time-consuming to remove.

Consider the Fumes

Your SPF roofing contractor needs to take into consideration that some coatings can emit strong odors while curing. Due to the fact that curing takes time, some precautions need to be in place. For example, air-handling units should be turned off and covered until the SPF is sprayed and the curing process has been completed. This will prevent fumes from entering your home or business.
