How to Prevent Commercial Roof Leaking

For commercial building owners, a leaking roof is one difficulty that needs to be dealt with fast. If it happens to be the rainy part of the year, procrastinating on fixing your leaking roof will cause you a lot of losses.

You will have your unwanted work stoppage in the company (involuntary loss of income), loss of materials (maybe damaged by the leaks), loss of man-hours (employees cannot work with their present conditions) and other losses.   

Preventing the leaks in the roof of your commercial building will first need some checks and inspections on the causes of these unwanted problems. Roofs may have different strengths and weak spots.

Let us discover some of the most persistent problems that can happen and knowing how to tackle each of them correctly.

Puddle Saturation

Many commercial rooftops are constructed mostly as flat surfaces. This type of surface definitely needs some form of drainage system to prevent buildup of water. Some puddles are natural (mostly happening after a storm); some puddles that persist for some few days can lead to a problem in the roof’s drainage system.

Another case is when water accumulates on a flat commercial roof can lead to leaks. The pooling water can put stress on a roof. (Every square foot of puddle water adds abut five pounds of weight per square inch on the roof.

Slanted roofs might have drainage problems and leaks along the roof’s edges if the gutters are not kept clear or the downspouts are clogged.

Flashing

Another cause of roof leaks is damage to the flashing that seals the roof along the perimeter and seams where the angels meet. The flashing is the protective seal against water and debris.

It can also be damaged by severe weather conditions or can come loose from heavy winds. The flashing can naturally weaken or loosen over time at is expands and contracts slightly during hot and cold seasons.

Membrane

Commercial roofs are sealed with a barrier protecting the raw roofing materials from the wind, rain and snow and other natural elements. This membrane allows the water to slide off of the roof into the drainage system.

As it ages, it becomes susceptible to cracks and blisters from debris and harsh weather. This can spread and rainwater can easily saturate through the cracks.  

Prevention strategies  

Prevention commercial roof leaking goes all the way first to the design. Standing water cannot form in well-designed roofs. Standing water is heavier than you can imagine and stresses your roof and develop leaks.

Like poor design, insufficient drainage can cause water to pool, resulting in the same consequences. Like all liquids, water will always find cracks and crevices in your roof. Make sure you have all these covered, clear and working properly.

Damages  

Over time, your roof’s membrane may crack, split or shrink – all of which can cause leaks. This is an integral part of the commercial roof, and you need to inspect it frequently.

The flashing is the protector of the membrane’s edges. They can expand and contract with changes in temperature, and this can cause gapping and leakage. They can also become loose in storms. Repairing them promptly prevents leaks.
