September should be about Fall Maintenance for your commercial flat roof. This is a service we do once a year to get ready for the winter rains. Our property managers have reported back to us that Fall roof maintenance greatly reduces winter roof leaks and extends the service life of the existing roof system. At Just Leaks, we have never had a management firm stop maintenance once they start.

What does roof maintenance look like? Here is what Just Leaks recommends for Autumn Roof Maintenance:

1. First, the drains and all areas of accumulated debris are swept clean.  Cleaning the roof in the Fall accomplishes three goals; exposing the roof membrane for inspection, removing debris, which can clog drains; minimizing the formation of mud, which stresses the underlying roof membrane and promotes weed growth.
2. After the roof is clean, it is then inspected and all minor defects are repaired.  This is done by first walking the perimeter of the roof, paying special attention to the drains and perimeter wall flashings.  The entire field of the roof is then inspected by systematically walking the length of each width of capsheet.
3. During this walk, the roof mechanic pulls a small cart with all the materials and tools necessary to repair the various defects (such as popped nails, fish mouths, small broken ridges, and blisters, mechanical damage, etc.) that are encountered.  The roof mechanic repairs each defect as it is found using the materials and technique appropriate for that repair.  Any foreign objects such as screws, nails, and stones are cleaned up at this time.

Even during a long drought, the commercial and industrial roofs in California require Autumn roof maintenance to prepare for the rainy season, regardless of the amount of rainfall. You can save yourself and your commercial tenants from leak damage if you take action in the Fall to do roof maintenance.

We know this is another HVAC installation – but it is the type of project the Just Leaks roofing team does very well. For those following our recent projects, Just Leaks hopes to get more HVAC installations and roofing projects from property managers and owners of commercial buildings throughout the San Francisco Bay Area.

This HVAC installation was challenging, in that we had to install new 20 foot beams in place and re-frame the roof to structurally support a new HVAC unit. Fortunately, we were able to do all the work from the rooftop and not disrupt the occupants. Our client was delighted we were able to reframe the roof deck and install the new capsheet roof and flashings in just 3 days.

The Just Leaks Team located the new HVAC position on the roof surface, and removed the existing capsheet area to access the underlying plywood and wood frame deck.

The Just Leaks roofing team removed the plywood and insulation, installed new 20 foot beams, installed new curb framing, and reinstalled the insulation.

Next, the Just Leaks team installed the new plywood roof deck, frame 4x curb leveler and installed the metal factory HVAC curb. Next, we installed the new capsheet roof over the new plywood deck.

To wrap up the HVAC installation, Just Leaks tied new roofing into the existing capsheet roof, applied acrylic coating, and set the HVAC back into position.

If you have a roofing question or HVAC project for Just Leaks, we will be glad to help. Contact us for an estimate or consultation by calling 408-249-4646.

Many owners and tenants of commercial buildings are interested in finding ways to lower their energy bills. Here are five easy ways to reduce the energy consumption in your industrial building.

1. Install automatic shut-off light switches. Even if you are using low-voltage lighting, it’s smart to install automatic shut-off light switches that power down a room when it’s not occupied. Encourage all building tenants to turn off the lights before they leave work.
2. Use Energy Star appliances and other energy-saving equipment. Not only do you save by lowering your energy costs with Energy Star appliances, but some equipment can earn you rebates, too. Check into all the energy-saving equipment available on the market for your commercial building and tenants’ industry requirements. The equipment you choose could make a big difference in your power bills.
3. Install water-saving devices. Lower your building’s water consumption by utilizing water saving devices on all sink fixtures. Replace older toilets with newer low-flow tanks. Encourage all building tenants to reduce water usage when possible.
4. Reduce air conditioning usage at night. If your commercial building is not required to keep electrical equipment and perishable goods at a lower temperature, consider turning off the A/C at night. The morning air should be cool enough to keep the inside comfortable when the air conditioning is turned on for the day.
5. Install or maintain a cool roof coating. Just Leaks helps many commercial property owners and tenants save big time on energy costs by installing cool roofs. Coated with AcryPly Polyester Membrane Systems or Spray Polyurethane Foam Systems, flat industrial roofs stay significantly cooler. Not only will a cool roof lower your energy bills, but it also benefits the environment.

For more information about cool roofs and how they can help lower the energy costs on your commercial properties, contact Just Leaks for a consultation. Our phone number is 408-249-4646, and we will be happy to assist you.

A recent project was a new HVAC curb and framing on a flat, commercial roof in the Silicon Valley region. Here are a few photos showing the progress of the project.

These photos show the new HVAC curb and framing. The new underlying frame supports the new HVAC and curb from under the roof.

The next photos show the top of the roof where the HVAC unit will go. We cut away the roof, framed in a level curb base, installed metal factory curb, insulate, and cant the curb.

After the foundation of the HVAC unit was built, we primed the roof curb and tie in area, installed base ply and capsheet roof membrane.

To finish off the new HVAC curb and framing installation, we reinforced the edges and seams so they would tie into existing roof membrane. This reinforces the bond at the transitions for a more durable seal.

If you are a property owner or business owner that needs to replace a rooftop HVAC unit, you can rest easy knowing that Just Leaks will do a complete and reliable job.
