Flat Roof Ponding

Is It Acceptable to Have Ponding On My Flat Roof?

By Allen Sensel

Moderate Water Ponding


There is a lot of speculation with older building designs and how their flat roofs have a tendency to collect pools of standing water referred to as ponding. The purpose of this report is to provide clarity for a commonly misunderstood notion that a flat roof, whether it’s asphaltic built-up, modified bitumen, or any kind of single-ply membrane, should not bear any kind of collection of rain water. I will provide brief examples from the IBC, U.S. Department of Housing and Urban Development, and Factory Mutual, all of whom mandate construction and renovation standards to comply with regional climates,weather patterns, and safety.


Ponding water, as described by the IBC and recognized by the U.S. Department of Housing and Urban Development, is water that remains on a roof surface longer than 48 hours after the termination of the most recent rain event.

Standing Water

This explanation from the IBC can also point out that directly following persistent rainfall, water is not considered standing until after 48 hours of dry weather, after which, can evaporate efficiently at temperatures above 45 degrees Fahrenheit. Only when the same volume of water exists after this period can there be a concern for potential leaks, providing that the roof system was properly installed.  The U.S. Department of Housing and Urban Development elaborates on how building inspectors approach ponding after an installation:

“48 hours before conducting a physical inspection, check the local weather forecast to see if precipitation is expected. If there has been precipitation within 48 hours prior to your inspection, use your judgement in deciding if observable ponding is due to the recent precipitation or because of an ongoing problem. Keep in mind that some flat roofs are designed to allow ponding.”

Concurrent with the size of the roof, Factory Mutual Global explains rain load on a dead flat roof:

“ Roofs should be designed with positive drainage: however, dead-flat roofs consistent with this guideline are acceptable.”

An older building will lack modern specifications for framing slopes a minimum of  1/4” rise per 12” run. The solution to controlling water flow on a dead flat roof, if ponding is still a noticeable concern after following the aforementioned provisions, is designing a framed slope for positive drainage to scuppers and/or bowl drains.

Cover-Boards: Purpose & Application

by Allen Sensel

Glass-Matt Roof Protection

When putting a low-slope roof together it’s important, as a building owner or engineer, to understand how to control moisture, combat mold, and provide fire protection. Cover-boards offer sufficient roof deck protection that meet these requirement for installing a roof. They can also serve as a purpose for re-covering your roof. These boards provide a clean, smooth surface to attach your next roof system to.

Glass-Mat Roof BoardUSG manufactures Securock, a glass-mat board that can be used on a flat roof for dimensional stability, surface protection, and overall increased lifespan of a structure. When installed correctly, Securock acts as vapor and fire barrier, keeping the roof membrane from developing mold and succeeding in fire standard ratings (rated at the maximum ’10’ with Factory Mutual [FM] Class 1 and a Class A Fire rating with Underwriters Laboratories [UL]). This is a great way to qualify for lower insurance rates as your building is less prone to fire damage.

One of the other benefits to using Securock is its ease of installation. The packaging is efficient and the board utilizes a high-quality, mat-to-core tensile bond, making each piece easy to cut and hand-break. This creates a faster labor work-flow and less of a mess to clean off of the roof surface, which helps to cut cost and keep workers focused on installing a quality roof as a whole.

As a local certified Seattle roofing contractor, we’re all about installing a quality commercial flat roof and so we recommend using USG Securock for our installations. We also specialize in single-ply residential roof systems. Give us a call at 253-445-8950 for a free estimate or drop by our website,

Ice & Water Shield: Why It’s Important For Your Home


GAF Leak Barrier Membrane

Leak Barrier Membrane

Let’s face it, Washington is rain prone which can eventually lead to ice dam build-up in the winter and early spring seasons among higher elevation neighborhoods. These homes will succumb to an inch or more snowfall more often than sea-level homes will. A key element in providing a functional roof system is what we call an ice & water shield.

GAF Materials Corporation

Here’s how it works. After a storm, ice can form along the eaves, skylights, chimneys, and roof vents of a house. This build-up counters the slope of the roof, catching water and debris. Ice & water shield membrane placed in a critical leak area offers weather-tight protection against the collected water, keeping it out of the attic and the rest of the house. Chimneys and skylights will typically trap water so metal back pans and crickets are used to keep the water sloping down and around them in conjunction with an ice & water shield. A lot of homeowners are having contractors use the protective membrane at roof hips, ridges, and valleys as well for additional protection in all critical leak areas.


National roof code indicates the requirement for ice and water shield must extend a minimum of 2 ft up from edge of roof eaves. Typically, contractors suggest at least 3 ft or more as the material comes in 3 ft wide rolls. Doubling the width to 6ft (with slight overlap between the two sheets) will create a better performing roof system and is typically required for upgraded warranties (for a roof system as a whole) with most roofing material manufacturers.


GAF Leak Barrier Membrane GAF Materials Corporation holds superb warranties on their roof systems with the correct installation of leak barrier membrane by a certified contractor. The Weather Stopper® System Plus limited warranty covers the first 50 years for 100% coverage against manufacturing defects including cost of installation labor when using a Lifetime Architectural & Designer shingle system (20 years on 3-tab systems). This system includes placing ice and water shield (GAF Weather Watch®, StormGuard®, & UnderRoof™) in valleys and around all penetrations of the roof. The deluxe warranty offered by GAF, Weather Stopper® Golden Pledge covers the above stated with the addition of workmanship coverage. This includes 100% coverage for misapplication for 25 years (20 years on  3-tab) and includes tear-off and disposal costs if a replacement is necessary. Ice and water shield must be properly installed in valleys, around all penetrations and doubled to at least 2 ft beyond the warm wall (exterior wall) for houses at 1500 ft elevation and higher. This leak barrier is not necessarily required along roof rakes, but is generally recommended by certified GAF installers.
