Having a roof over your head means that you have already gone through the different types of roofing systems and have managed to settle on one. Commercial Roofing is a roofing system that is popular with home owners as the metal roofs are very durable and versatile. They also conserve energy by reducing the consumption. This can be seen as some of the buildings use solar roofs to power their building
Despite all these good things, the roof may have some glitch causing roof leaks that may have been caused by the following things:
- Pooling Water.
- Damaged roofing membrane.
- Damaged flashing.
- Improper Sealing.
- An Aging roof
POOLING WATER
This is also known as Ponding water and if ignored, it can have long-term effects such as a leaking roof, damaging the interior of the building, faster deterioration of the roof’s coatings and materials and also Increases the exposure of the ponding area to damaging ultraviolet rays. A flat roof of a commercial building that isn’t levelled might collect a pond of water which may pull in different areas causing the roof to sag or leak. Caused by a number of things such as poor drainage systems or structural issues
However, this can be fixed by a number of things such as:
- Fixing Low Spots on Flat Roofs.
- Unclogging or opening Existing Drains.
- Mounting Additional Drains to Redirect Water.
- Applying a new coat to the Roof.
DAMAGED ROOFING MEMBRANE
A roofing membrane help seal flat roofs and make them waterproof. Conversely, as weather changes from season to season, keeping up with your maintenance plan is good idea as it will keep roof blisters from popping up your commercial flat roof. This is a raising in the roof where there is no linkage. Air or water can fill up the area thus bringing about a blister, which looks like a bubble on your roof.
Climate change can cause the blister to grow daily as air or water is trapped inside. When it’s daytime, the water or air will expand due to warm weather, and at night, contraction shall be caused by cool temperatures. Moisture will seep its way through if the blister is left untreated, leading to a widespread repair.It can be initiated by a number of things, including Moisture, poor installation and poor ventilation.
The prevention of the same can be done by using dry materials, proper installation and doing a regular inspection of the roof, regardless of it being old or new.
DAMAGED FLASHING
Flashing protects your roof membrane’s exterior edges and also helps seal the area around the chimney and vents. As a roof may be damaged by the weather and fluctuating temperatures, the flashing can expand, contract, and become loose, creating an entry point for water, allowing it to pour under the membrane. If your flashing breaks, it could cause the underlying roof structure and ceiling to deteriorate due to moisture damage.
Various factors can cause flashing, including:
-
- Poor installation – Flashing must be properly installed on a new roof, as a sloppy or inexperienced job will quickly lead to leaks.
- Poor repairs – Repairing a flashing must be done in the right way, with the right nails, laps and sealant. Failure to do this will lead to a leaking roof.
- Age and exposure – Flashing may warp through temperature changes, bend because of how your house foundation is settling, or develop problems with rust and residue. Old flashing should be replaced before it causes widespread issues.
IMPROPER SEALING
The purpose of a roof membrane and flashing is to make your roof as waterproof as possible. This isn’t so effective when you have other points on the roof where water can flow in unchecked. Pipes, vents and drains all need to be properly sealed to prevent leaks from occurring, otherwise, they act as holes in the membrane.
AN AGING ROOF
Despite the term old is gold, a roof may need to be replaced as some of them, such as flat roofs have a lifespan of 15 or 20 years. An old roof may experience various problems as they have gone through everything including adverse weather conditions that eventually weaken the roof itself.
The durability of a roof depends on how well you maintain it. Knowing the causes of a few problems such as leaking roofs enhances your knowledge thus knowing what to be on the lookout for.
