Commercial roofing often has different needs than residential roofing does. For one reason, commercial roofs are often flat or have very low slopes. Asphalt shingles, which are common on residential roofs, can't be used when the slope of a roof is low or flat.
Instead, commercial buildings use roofing materials that can keep rain from getting under the roof if rain doesn't roll away quickly. That means you may need to choose built-up, membrane, spray foam, or metal roofing. Here are some situations to discuss with your commercial roofer that can help you decide on the right type of roofing material for your building.
Consider If A Roof Restoration Is Possible
Ask your commercial roofer about restoring your old roof rather than replacing it. Restoration isn't always possible, especially if your roof has significant water damage. When restoration is possible, you might save quite a bit of money while getting many more years of life from your roof. Your roofer might restore your old roof by applying a protective watertight coating on it. That means you'll save money because you don't need to tear off the old roof or invest in new roofing materials.
Share Concerns About Environmental Pollutants
Your roof is exposed to harsh weather, UV rays, and pollutants in the air around your building. You need commercial roofing that can tolerate the unique exposures it faces. For instance, if you own a restaurant, there may be greasy exhaust vented out on the roof, and you'll want a roofing material that won't be damaged by grease.
If your building is in a commercial or industrial location, there might be acidic pollution in the air that could eat away at certain roofing materials. A commercial roofer can help you select the best roof for your building that takes into account the daily exposures that could potentially cause your roof harm or make it age faster.
Ask About Durability And Longevity
Any commercial roofing material can be damaged by a strong storm or impact. However, some commercial roofing materials are more durable than others. When you want the least amount of maintenance and repairs, and the longest life for your roof, you should choose the most durable material for your situation. More durable might also mean more expensive, but the extra cost upfront can pay off over time in lower repair costs.
If you opt for a membrane roof, ask your roofer if you should install walkways to minimize the risk of punctures when people walk on your roof or provide maintenance to rooftop equipment.
Another important thing to consider is cost. If you have a large building, the cost of a new roof could be significant. You probably want the best roof you can afford, but you'll also want to consider durability and longevity so you spend your money wisely.
