If the old roof on your building didn't last as long as you anticipated, or if it has needed a lot of repairs, then you may want to talk to a commercial roofer about the pros and cons of metal, spray foam, and membrane roofing. Each type of roofing has its good points, and all roofs need to be maintained properly. Here's how metal, spray foam, and membrane roofing materials compare, and how to choose the right roof for your building.
Metal Commercial Roofing Is Attractive
Metal roofing can last a long time without the need for many repairs. However, scratches and other damage should be repaired right away if they happen so rust doesn't become a problem. Metal roofing comes in different styles and colors, so if the appearance of the roof is important, metal could be a good choice.
If your building has a steep slope and can be seen from the parking lot or street, you might prefer the look of a decorative or colored metal roof. However, appearance isn't the only reason to opt for metal. Metal offers fire protection, and it doesn't decay as long as rust is removed before it gets out of control. Metal can also tolerate being walked on without fear of punctures.
Spray Foam Roofing Has No Seams
An advantage of spray foam roofing is that it has no seams. That reduces the risk of roof leaks over the life of the roof. The foam spreads out to form a single, continuous protective layer on your roof. Spray foam is also durable and not as easy to damage as membrane roofing. It's also easy to repair.
Spray foam roofing costs less than a metal roof. That could be important if you own a large building. There's not much variety in the appearance of a foam roof. It sprays on white, but that might be an attractive look for your building, especially if it has a flat roof. Plus, white reflects the sun, and that can help prevent solar heating of your building's interior.
Membrane Roofing Is More Affordable
The big advantage of membrane roofing is that it is a more affordable option. This can make it an enticing choice if you have a large building with a flat roof. While some types of membranes are easy to puncture, the damage is usually easy to repair. A membrane roof needs to be checked and repaired regularly, but all roofing needs to be monitored so damage can be caught early.
Consider the type of building you have, the slope of the roof, and your budget when you think about the type of roofing you want. You might want metal so your building looks professional, and so the roof will last for decades without the need for much care, or you may prefer the lowest cost option and include regular roof care in your maintenance schedule. A commercial roofer can offer guidance and advice so the choice you make is one you're happy with for years to come.
