Posted on: April 14, 2016

Seal Maintenance Program for Commercial RoofsRoofs serve as our protector. They keep us dry, warm and shelter us from the unpredictable outdoor elements, such as heat, rain, wind, hail and snow. Proper maintenance, thorough care and meticulous sealing are crucial to ensure the safety of our homes, offices and the people within them. This is why Chinook Roofing & Gutters offers a SEAL Maintenance Program, a systematic commercial roof maintenance program designed to reduce the frequency and extent of oversights.

The SEAL Maintenance Program starts with a thorough routine roof inspection that complies with and investigates all properties that align with all roofing standards. The following roof elements are considered during a commercial roofing inspection.

Exterior Roof

This step of the inspection considers all exterior wear and tear of a building. Signs of major and minor leaks are investigated. Staining or missing mortar along the exterior walls are all scrutinized. Even when it looks like there are no signs of a problem, the metal work and parapets could be an underlying issue.

Interior Roof

Once the exterior has been thoroughly inspected, the interior comes next. SEAL technicians look for any leaks and deterioration along the internal building walls. The ceiling along with the bottom side of the roof deck (if available) are also investigated throughout this portion of the inspection.

Roof Perimeter

This step requires a thorough inspection of the flashings of the roof. For those who do not know, flashing helps direct the flow of water around openings. Flashing is a heavily trafficked by water, hence why it is such an elemental part of Chinook’s SEAL Maintenance Program. All base flashings, counter flashings and fascia flashing/copings of the roof perimeter are checked. Furthermore, SEAL technicians also check for leaks, staining, missing mortar, lifted edges, term bars, and debris build up.

Roof Field

Next, the field of the roof is inspected. The field can commonly be a victim of excessive foot traffic, membrane overlaps and other trades damage. SEAL technicians will clear gutters, drains and downspouts. Additionally, they will inspect coatings, strainers and clamping rings. Lastly, an examination of any oil deposits, surface contamination, soft area, vandalism and ponding water issues is inspected as well.

Roof Penetrations

Finally, all HVAC units, duct work and any accompanying electrical work are checked. Not to mention, pitch pans, plumbing vents, positive flow vents and roof vents are inspected for excessive wear or defects.

This may sound like a great deal, but it is important! The commercial roof of your building may be overdue for an inspection. That is why our SEAL Maintenance Program has you covered. So ask yourself, are you SEAL’d? Check out our SEAL Maintenance Program for residential roofs too!
