Low spots in flat roofing are common and can cause damage and expensive repairs if not taken care of. But how do you know if you have any low spots? There are signs to look for to identify a low spot, so you can contact a roofer to help get it taken care of before it causes too much damage.
Checking if Your Flat Roof has a Low Spot
Pooled water: Flat roofing is not completely flat and has a small incline. This allows water to drain off to the gutters away from the roof. Water that has pooled or accumulated is one of the first signs that you have a low spot, as it prevents water from its natural flow down the gradient. These pools will weaken the roof and eventually cause leaks and even structural damage to the roofing system.
Clogged drains: When drains or gutters are clogged, they collect water. The strain of the backed-up water weight can cause a low spot. You need to check your drains regularly and clean them out if you notice clogs. You should then check to see if water runs off, if not, then you may have a low spot.
Collected dust: Low spots provide protection from the wind for leaves and debris so piles on the roof could indicate a low spot. Collected dirt and debris can also become heavy like water causing damage to roofing materials. You need to clear these out and get the low spots repaired right away.
Concentric sediment circles: Unless you are on the roof directly after it rains, then you may not see any puddles. They do leave tracks though. Puddles will leave concentric circles after the water has evaporated that indicate there was once a pool there. These circular deposits let you know that you have low spots.
Moldy smells: Pooled water can collect bacteria which can increase chances of mold growth and odd smells. Black mold growing on your ceiling or strange musty smells can indicate that water is collected on the roof in a low spot.
Changes in the ceiling: If your ceiling is sagging, stained, or dragging, then you have a low spot in the roof. Low spots collect water which becomes heavy and causes leaks into the building. The signs will be apparent on your ceiling before you even identify the spots on the roof.
