If you noticed something doesn't look quite right with a few of the concrete roofing tiles on your commercial building, then it is important you inspect them without causing additional damage to the roof. Though concrete tile roofs are very durable, the tiles will crack if you attempt to walk on them. Once tiles have cracked, then the roof's plywood sheathing becomes exposed to the elements and the roof will develop a leak.
While the best person to inspect and repair your commercial roof is always going to be a licensed roofing contractor who specializes in tile roof maintenance, these tips will help you safely evaluate the problem if you go the DIY route.
Tip: Inspect the Damage from a Ladder or Surrounding Building
To get a better look at the potential roof damage without climbing up on the roof and risking cracked concrete tiles, inspect it from a ladder or a surrounding building. You can use a pair of binoculars to get a better look at the roof from your perch on a ladder or by looking out the window of a surrounding building that has a clear view of the problem area.
Tip: Replace Cracked or Broken Tiles ASAP
If you discover the tiles you noticed are cracked or broken, then it is important to get them replaced as soon as possible. Unless the tile is along the outer edge of the roof where you can safely replace it while standing on a ladder, you need to have the tiles professionally replaced.
Tip: Remove Biological Contamination from the Ground with a Roof Washing Product
If you discover the tiles are not damaged but are actually having a problem with biological growth such a mold, mildew, fungi, or moss, then you can easily solve this problem yourself safely from the ground. There are many products available at your local hardware store designed to be used with a pressure washer to clean tile roofs and kill biological growth. When pressure washing a concrete tile roof, use the low setting to prevent pitting damage to the tiles.
An Important Note About Your Tile Roof's Future
It's important to note that you should avoid the future installation of any HVAC equipment, satellite dishes, or other hardware on a commercial building with a concrete tile roof. Since the tiles are easily damaged by humans, it's best to avoid giving anyone a reason to ever need to walk on your roof other than the occasional professional commercial roofing contractor.
