How to Determine Whether Your Commercial Roof Needs Replacement
Roof experts and all roof-related articles you read on the internet always remind you that you should properly maintain your commercial roof and replace it once it reaches its lifespan. However, they might not tell you about other situations that require a roof replacement.
If you are a commercial property owner who has no clue on when you should call roofing professionals, you only need to do two steps to determine whether your roof indeed needs a replacement:
Step 1: Inspect From the Outside
The first thing you can do is visually inspect your roof from the outside. Here are the things you should evaluate:
- For Metal Roofs: Check whether any form of rusting is building up on your metal roof. Corrosion often occurs in roof areas with overlapping edges. When there is rust, affected parts of the roof weaken, affecting the whole structure. Be wary, especially in the places where the screws and nails are. These are where water usually pools down and leads to rust.
- For Tiled Roofs: Tiled roofs are prone to becoming loose on the ridges. Clay roofs, in particular, are brittle and can be easily chipped or broken. Strong impacts from falling objects or someone walking on it can create even more damage. In such cases, inspect all the tiles to determine the extent of the damage.
Step 2: Inspect From the Inside
Now, it is time to go inside and look for other warning signs:
- Check Your Roof Board: You may have a damaged roof board if visible patches let daylight into your space. If you see that the outside light is shining through your roof, it could mean that your roof has possibly weakened and needs to be replaced soon.
- Check the Roof Deck or Ceiling: If you see that your roof is sagging, it is a sign of water damage that has affected your roof. Sagging occurs when there is excessive weight to the structure. It can be caused by snow, ice, wind, or water leaks. Even putting too many shingles onto one’s roof can damage the sheathing underneath it. If you overlook this issue, it can lead to safety risks, such as roof collapse and water infiltration.
Check for Other Signs of Water Damage or Leaks: Inspect your roof board for other signs of water damage or leaks. Dark spots and trails, stains, bubbles, and molds can also be signs that you need to fix your plumbing system to avoid further damaging your roof. Water damage usually happens when outside rainwater enters the roof through the loose bolts and screws. It can lead to other problems like rusting and, worse, the weakening of the roof.
Conclusion
In general, if at least one-fourth of your roof is already damaged, it is time you consider replacing its entirety. Roofs will eventually age, reducing their durability and ability to protect those who live under.
Every roof’s lifespan depends on what it is made of and how it is installed, so now that you are considering replacing them, make sure that you choose the best roofing materials and services that you can.
