Semi-Annual Roof Inspections Ensure a Watertight Building

Posted by Nicole Gale on Thu, Sep 14, 2017 @ 08:52 AM

Conducting a roof inspection before the wet seasons can help prevent many issues that lead to roof leaks and failures.

Below is a complilation of pictures addressing the most common roofing issues that occur. Proper roof maintenance and inspections allow you to avoid these major repairs; however, when they are avoided or overlooked, an expensive roof repair project could be waiting for you after that first rainstorm occurs.


1. Ponded Water: Ponded water can cause the surface of the roof to delaminate, blister, peel, and compromise adhesion of the roofing system to the building’s substrate.  This issue needs to be fixed immediately. To remedy ponded water, the AcryShield SPF Roofing System allows you to create a custom slope in areas where ponded water typically occurs, allowing the standing water to flow towards a drain.


2. Impacted or Clogged Drainage: A plumber is recommended to unclog the drain and then the ponded water needs to be inspected to make sure no further damage has occurred. (See Ponded Water above more information.)


3. Large Blister: Blisters occur because of several reasons, including: adhesion issues, ponded water, an aging membrane and more. This is another issue that needs to be fixed immediately as water penetration is likely to occur. Contact a Roofing Professional with zero obligation to determine your next steps to restoring your current roof.


4. Debris from Overhanging Trees: Branches can cause abrasions on the surface of the roof making it important to clip them away. Clogged drains and ponded water can occur from leaves, branches and other items that fall onto the roof. Ensure the rooftop is clean and free from any debris.


5. Mastic Cracking at Pipe Jack: When seals are failing and not functioning as designed, water penetration can occur. All joints and flashings need to be inspected to ensure seals have good flexibility (not brittle), adhesion, and water resistance.


6. Plant Growth: Weeds, trees, and plants can grow out of the smallest cracks on your roof. Carefully remove any form of plant growth immediately as this can cause several issues including: improper drainage, damage from roots, inadequate adhesion, ponded water, etc… Do not pull or yank the plant from the roof as the roots may have penetrated through the surface and this could cause even more damage. Contact a roofing professional if you think this could be the case for your roof.
