SOLARBUILDERMAG.COM | 33 Penetrating protection In areas with high winds, on metal buildings and other external factors that could adversely affect solar arrays (think earthquakes), arrays must be attached to the roof. To accomplish this, solar install- ers are often forced to penetrate the roof membrane. Penetrating installations are the cause of sleepless nights for build- ing owners. After all, the solar installer is asking to poke holes through part of a structure that costs significant money. Any poorly sealed holes will cause problems for the roof itself and potentially allow rain or wind to reach beneath the roof and damage the inside of the building. Unfortunately, some solar installers don't know what it takes to seal the penetrations properly, and as anyone who's ever had a leaky roof knows, locating the problem is difficult by the time the damage is discovered. That's where SPF can help. We often use SPF to restore roofs under the arrays we install. When you combine SPF with a quality liquid membrane, not only do they self-flash, but they provide a double measure of protection from the weather. Finally, having a sturdy underlayment adds even more strength to the roof, making it an even better investment for the building owner. The best use of SPF roofing we've seen, however, is at building conception. If the long-term plan is always to add a solar array to the roof at some point, SPF roofs allow the construction company to make the building "solar ready" by installing solar stanchions (legs). Building owners can speed solar installations with such advance planning and get to the fun part of having a solar array — saving money — more quickly. Perfect pairing Like a perfectly prepared filet and a well-rounded pinot noir, SPF roofs and solar arrays beautifully complement each other. Combined, they allow commercial building owners to save through solar electricity production and improved energy effi- ciency with the outstanding insulative properties of SPF and the reflective characteristics of a quality liquid membrane. This col- lective approach will help companies reach their sustainability goals faster and with greater success. Though SPF is currently something of a niche product, we believe it is gaining a much wider following with each successful installation, among both solar installers and commercial building owners. In time, we believe it will displace conventional insula- tion methods, which will be good news for building owners and solar installers alike. Daryl A.
