The drainage system on your roof is one of the most essential parts of the entire roofing system. Your commercial property is at risk of water damage if you don't allow the water from rain to go down the gutters and downspouts, as opposed to sitting on your roof or dripping down the exterior walls of your building. Even if you had a high-quality drainage system installed, you still need to clean the gutters and maintain the drainage system on a regular basis. Here are some important maintenance tasks for the gutter and drains on a commercial roof.
Empty the Gutters
The first thing you need to do on a regular basis is clean out the gutters. Even if you haven't had a storm or inclement weather recently, you likely still have some leaves, twigs and other debris that has made its way into the gutters. Even a light wind can blow debris onto your roof, which then eventually makes its way down into the gutters. Use a ladder to get up to the gutters that is taller than the height of the gutters. You don't want to be reaching up or straining to access them, but be able to look directly over the gutters. This prevents injury as you begin cleaning them out.
When cleaning out the gutters, look for signs of broken shingles or roofing tiles, as pieces from these roofing materials might have fallen into the gutters. If you see broken pieces there, you know you have damaged roofing materials that need to be replaced. You also want to check the gutters for standing water. This is a sign of a blockage somewhere in the gutters that needs to be removed.
Check the Roof Drains
Find your roof drains and clean them out thoroughly. You can get the same debris and blockages in the drains and downspouts as what you find in the gutters. It is important that all drains are completely cleared out. If while inspecting the drainage system and downspouts you notice holes, racks or other damage, make a note to call a roofer. They may need to be repaired or replaced. It is important to get them repaired before the next big storm or you might have a lot more severe damage on your hands.
Trim Nearby Trees
The last thing to do is to find nearby trees that reach the height of your roof and have them trimmed or cut down completely. These trees are a risk to your roof in multiple ways. First, the leaves and twigs are likely falling onto your roof and into the drainage system, causing a bigger problem than is necessary. This creates more work for you as you need to clean out the building's drainage system more often. The tall trees can also cause damage to the roof and siding during heavy wins.
