Commercial solar panels are becoming an increasingly important part of the building landscape. With their wide flat roofs, commercial buildings are perfect for solar installations, which can bring many benefits to a building:

Critical infrastructure must always be protected – and hospitals are critical infrastructure. Hospitals don’t have downtime – they can’t have downtime – because they literally represent life support systems for the people inside them. Any loss of power or operations can put peoples’ lives at risk.

Rooftop supports are extremely important when it comes to extending the lifespan of your commercial roof – as well as increasing the safety of contractors and maintenance crews who work on your elevated surfaces. With that said, not all rooftop support systems are created equal.

Not all roofs are created the same – or even with the same pitch. When we talk about commercial roof slope, we usually talk about a completely flat roof. With that said, not every commercial roof is flat. Sloped commercial roofs are common in several parts of the country, either for decorative or weather-related reasons.

This year, as in years past, retail sales are expected to be literally through the roof. Not only do retail sales tend to spike between October 31st and December 25th, this year’s spike is expected to be up to 5 percent larger than in 2018. All told, consumers are projected to spend up to $1.1 trillion during this year’s holiday season.

Winter is approaching across the Northern Hemisphere, which means it’s time to prepare for thermal expansion—and its more dangerous cousin, thermal shock. 

If treated correctly, your roof could last anywhere from twenty to fifty years. Simply lasting is not a measure of roofing success, however—instead, you’ll want to look at lifetime costs. Picking the right commercial roofing materials up front, treating them properly, and investing in the correct infrastructure and maintenance programs will make your roof more efficient and more likely to last its full lifetime without incurring significant costs.

Very few people should ever get to see what it looks like on top of a commercial roof. Rooftops are unequivocally dangerous, with falls from rooftops representing over 33% of deaths in the construction industry. By this metric, building owners need to make it relatively difficult for anyone to get on top of a commercial roof, with barriers in the form of locks, special training, permission slips, and time sheets. In short, no one should be able to access your roof without learning about its safety features, getting a key from a designated individual, and logging their time.

There’s a different side to the coin, however. Once your workers have passed the hurdles you put up to prevent them from freely accessing the roof, they should be able to get around easily and safely. This means the addition of handrails to roof edges and elevated spaces, crossover ramps to traverse elevation changes and cable runs, and access platforms next to maintenance equipment. This allows workers to get to rooftop job sites and perform mission-critical job functions in comfort and safety.

What’s the difference between a good rooftop design and a bad rooftop design?

Functionally speaking, a “bad” rooftop design will express itself through the results. You’ll find that a bad rooftop design requires extensive maintenance more often. A bad rooftop design will have poor fit and finish—there will be gaps between flashings and penetrations, and the edges may be composed entirely of roofing tar. You’ll begin to find leaks within months of the roof’s completion.

A bad roofing design will have poor conformity to building regulations. It may not be able to resist uplift forces. It will leak energy due to poor insulation, and you will be forced to spend more money to heat and cool the building. Between constant repairs and increased energy costs, you’ll spend more money maintaining the roof than you did on its initial construction.

Here’s the thing—there are all outcomes of poorly-optimized rooftop design. How do you catch these design flaws before they’re embodied in plywood and membrane—and before they start costing you money?

When someone falls, someone gets hurt—and the risk is doubled if you’re on top of a roof. Even if you fall on a roof (as opposed to falling from the roof to ground level or a lower-level roof structure), you can still be in considerable danger. That’s because a roof may contain hazards that you wouldn’t want to impact with your body, such as pipe supports, live electrical equipment, or rusted metal. There’s even a danger of falling through a roof if you happen to be standing near a weakened area or a skylight. In other words, rooftop fall protection is more important than most may think.

With so many hazards in play, it’s no wonder that roofing accidents make up over one-third of all fatalities in the construction industry. Since you believe in worker safety—plus avoiding fines and bad publicity—it’s likely that you are interested in the guidelines and techniques that make up rooftop fall protection and prevention. Here are the top four ways to get started:
