Sometimes you need a clean slate. As the name implies, a full tear-off involves the complete removal of your existing commercial roofing system, allowing us to evaluate your decking and determine the existence of any underlying conditions. It also ensures we bring your roof system up to energy code, meaning less strain on your HVAC systems. Attention to detail is how Simpson proudly does business. We don’t just find immediate solutions for problems. We perform every duty with a complete understanding of your building envelope and a thoughtful, tactical approach to maximizing its lifespan. Intelligent design and professional integrity are ingrained into the Simpson DNA.
Known more casually as a “roof over,” a roof recover system is our default prescription for an existing commercial roofing system whose substrate integrity is intact and shows no signs of moisture infiltration. A “roof over” provides up to a 20-year material and labor warranty, making it exponentially more cost-effective than a full commercial roof replacement. This is our cost effective solution that gets you back to work fast without throwing a wrench in your budget.

Built-up roofing, known more commonly as BUR, is widely considered the “original” roofing system. Having been around for over 100 years, it has been a reliable flat roof staple of the industry for as long as modern commercial roofing has been done!
Owning and managing a commercial roof is a lot like owning a car; while the initial purchase is the biggest expense, getting the most out of it requires routine maintenance, proactive care, and, inevitably, repairs.
Good news, building owners and managers: your roof may have more life in it yet! By conducting major repairs or applying a tried-and-true liquid applied roofing system “coating” to your existing roofing system, you can prolong the life of your roof by 10, 15, or even 20 years before needing a full replacement, while keeping maintenance costs and safety hazards low.
A roof is just a roof, right? Something to cover your head and keep the tenants, assets, or whatever else is inside safe and dry? How different can a commercial roof be from a residential roof, other than the types of structures they’re built on?
EPDM roofing, or more formally “Ethylene Propylene Diene Monomer” roofing, is a type of single-ply roofing membrane that has remained a popular, time-tested staple of the commercial roofing industry since the 1960’s. EPDM is readily available and relatively straightforward to install, meaning less labor costs than other more complex roofing systems. Thanks to its traditional installation options and easy repairs/maintenance, it’s an economical roof option with lifespans that can exceed 30 years.
