If your commercial building is in need of a new flat roof, you have an array of options to consider. Rubber, rolled asphalt, built-up roofing: they all have their places, but if you want a roofing material that is really going to stand the test of time and benefit your structure, you'll want to strongly consider going with spray foam. Spray foam roofing is becoming more common as building owners and contractors become aware of its advantages. Here's a closer look at what spray foam roofing is and what advantages it offers.
What is spray foam roofing?
Spray foam roofing is a roofing material made from dense, water-proof foam. This is not the type of foam used to make couch cushions or bedding. Rather, it's a closed-cell foam that's hard to the touch. The chemicals used to make spray foam roofing start off as two liquids. The contractor sprays them into the roofing surface using a specialized applicator that mixes the two components together in an exact proportion. As the two liquids mix, they react to create a dense foam that clings to the roofing surface and hardens over a period of several hours. This surface is impervious to water and durable enough to walk on. Spray foam roofing is typically used on flat roofs.
What are the advantages of spray foam roofing?
With most other roofing materials, there are some seams. These seams often become the sites of leaks if they come apart or start peeling back at all. Spray foam roofing is seamless. The foam solidifies into one solid mass, so you don't have to worry about water seeping in along seams. There's also no need for flashing with spray foam -- it seals directly to protrusions like vent stacks or air conditioning units -- so there's no worry of damaged or leaking flashing, either.
Spray foam is lightweight.
Especially if your building is aging, adding a heavy roof may compromise the integrity of the walls or foundation. But spray foam is incredibly lightweight, so it minimizes strain on the rest of your structure and can be used even on less-stable older buildings.
It lasts for many years.
Spray foam roofing can last up to 50 years, which means you probably won't have to worry about replacing your commercial roof again in your lifetime. You will need to have the roof periodically re-coated with polymers to enhance its water resistance. However, this is a minor job that should only take your roofing contractor a few hours. Spray foam technology has been around since the 1950s, so its durability is well established.
It's an excellent insulator.
Heating and cooling a large commercial building can cost you an arm and a leg. Spray foam roofing will help bring your energy bills down. It's an excellent insulator, keeping cold air inside during the summer and heat inside during the winter. You could save up to 30% on your energy bills by choosing spray foam over other roofing options. Choosing spray foam insulation may also prevent you from having to install additional insulation beneath your roofing membrane, as you would have to do with most other types of flat roofing.
Installation is fast and easy.
Applying an asphalt or rubber roof can take days or weeks. Your contractors will have to remove the old roof, and then spend countless hours hauling heavy roofing materials onto the roof before they even start applying them. You'll have to pay for all of those labor hours. Spray foam roofing, on the other hand, is fast and easy to apply. You'll be paying your contractor for fewer labor hours, and you won't have to worry about shutting down your business or cutting back on operations for as long of a construction period. The length of the job will depend on your roof's size and the climate in your region, so check with a spray foam contractor for an accurate time-frame estimate.
If you're looking for a long-lasting, energy-saving, quick-to-install roofing option, spray foam roof coatings surely fit the bill.
