The climate in Arden and Buncombe County presents specific challenges for commercial roofs. Significant rainfall occurs throughout the year. Your drainage system must work perfectly during every storm. When water stays on a roof for too long, it creates ponding.
Ponding water adds immense weight to your building's structure. Over time, this weight causes the roof deck to sag. This leads to even more water collection. Proper drainage helps moisture move away from the roof surface. This protects your shingles, metal panels, and flat roof membranes.
Interior drains are commonly found in large, flat commercial buildings. These drains sit at the lowest points of the roof. They connect to pipes inside the building. These pipes carry water through the interior and out to the storm sewer.
Contractors cut scuppers into the perimeter walls or parapets of a roof. They allow water to flow off the roof and into exterior downspouts. This system moves large volumes of water quickly during heavy rainstorms in Arden.
Property owners often use gutters on commercial buildings with sloped roofs. These systems catch water at the roof's edge and direct it toward downspouts. Use heavy-duty commercial-grade gutters to handle large volumes of water.
Several factors cause a drainage system to overflow. The most common cause is the buildup of debris, such as leaves and twigs. Blocked drains or scuppers force water to pool on the roof surface.
Another issue is an undersized drainage system. Drains or gutters fail if they cannot handle your roof's square footage. Frozen water also blocks pipes and prevents flow during winter months.

You can take several steps to help your roof stay dry. Regular maintenance is the most effective way to prevent overflows.
A good rule of thumb is the 48-hour rule. Water remaining on a flat roof for 48 hours indicates a problem. In these cases, contact a professional to identify the blockage or design flaw.
A professional inspection from Integrity Roofing, LLC goes beyond a simple visual check. We comb over every square inch of your flat commercial roof. We look for cracks, bubbles, and blisters that lead to leaks.
Early detection saves money. By finding a small drainage issue today, you can avoid a total roof replacement. Our team provides a comprehensive assessment of your roof's health. We offer affordable solutions to keep your drainage system flowing.
Inspect your drains at least twice a year, typically in the spring and fall. Schedule an inspection after any major storm with heavy wind or debris.
Signs include standing water, ceiling stains, mold growth, and sagging roof decks. Water spilling over the sides of your building often indicates a clog.
Yes, a professional roofing contractor can often add overflow scuppers to an existing system. These act as a backup if debris blocks your primary drains. They provide extra protection against flooding.
Water should completely drain from a flat roof within 24 to 48 hours. Water staying longer than 48 hours is ponding water. This causes damage to the roof membrane and structure.
Do not wait for a leak to damage your inventory or equipment. If you are concerned about your Arden property, Integrity Roofing, LLC is here to help. We provide thorough inspections and reliable repairs for businesses throughout Western North Carolina.
