As we continue through the last few months of winter it is important to know how to keep your commercial building in tip top shape, and that includes your roof. The accumulation of snow and ice on your roof can cause considerable damage, but there are things you can do to protect from damage and extend the life of your roof.
Inspect annually for vulnerabilities and trouble spots
Every year you will want to check your roof for any issues that could make it susceptible to snow and ice damage. Repair any gaps around seams, joints, and flashing, as well as any rooftop equipment. Address any damage to the membrane, especially around curbs and drainage sites, and check for any buckling or damage to structural components. If your roof is in need of substantial repair, you may save money down the road by performing at least a partial if not full restoration to shore it up for wintertime performance.
Know your roof’s weight limits and check for warning signs of structural damage
It can be difficult to know just how much weight your roof can bear, but there are some clear signs of damage from excessive load. Check your ceiling for any sagging or cracks, and look for bowing in load-bearing beams and walls. Displaced lighting, pipes, air ducts, and ceiling tiles may also indicate a compromised roof. Additionally, substantial depressions in the roof, or any leaking, could point to serious damage. Structural deficiencies in your roof should be fixed immediately. Correcting these prior to coating can typically save you money and aggravation.
Know when to remove snow from your roof
Even if your building is not showing signs of structural roof damage, it is important not to let snow and ice accumulate beyond its load-bearing capacity. The longer that snow builds up on your roof, the more damage it may do. After large storms, or long periods of below-freezing temperatures, you may need to remove snow from your roof. When removing snow, it’s important to take proper safety precautions, and to use techniques that will not harm your roof.
Use de-icing and melting materials that will not damage your roof
Having to remove snow from your roof can be prevented with the use of de-icing and melting materials and equipment. However, using products that are not compatible with roofing materials can cause even more damage. Before using de-icing chemicals, check to make sure they won’t cause deterioration in roofing materials.
Clear gutters for proper drainage
It’s always a good idea to keep drainage systems clear, but it’s especially important when it comes to snow. Any other precautions you take are pointless if the water has nowhere to go after a melt.
Protect your roof with a coating system
Snow and ice will worsen any flaws in a commercial roof, and moisture will always find a way to exploit those flaws. One of the best things you can do to protect your roof is to apply a coating system that will shield it from moisture penetration. This measure is especially effective at preventing damage from freeze and thaw cycles, and has the added benefit of protecting your roof year-round, not just during winter.
