Autumn and Spring are optimal times to professionally clean your industrial flat roof. The reason? Cleaning your industrial roof at this time of year is a great time to inspect the roof and prepare it for the rainy season between October – February, and high temperatures in June – August.

When you have your commercial flat roof cleaned by Just Leaks, you can count on us to remove debris like tree branches, abandoned equipment or parts, leaves and trash remnants.

Sometimes flat, commercial roofs can get dirty when there are walls around the perimeter of the roof, as well as tall trees surrounding the building. If you want your roof to be clean and bright again so it can retain its reflectivity, the Just Leaks team will be happy to clean and inspect your roof. Not only do we have the tools, non-solvent cleaners, and the experience to properly clean the roof membrane, but we will also take photos of any areas that require repair or maintenance.

Fortunately, most flat, commercial roofs in the San Francisco Bay Area and Silicon Valley do not get too dirty. Still, most roofs do acquire fallen leaves and trash that is blown on the roof from winds. A professional roof cleaning from Just Leaks will ensure that the drains will remain unclogged from debris, and there will be less risk of water pooling on the roof, which could develop into leaks and water damage.

Commercial roofs benefit in many ways after a professional cleaning, including:

• Improved Membrane Performance
• Improved Energy Savings
• Visual Inspection of Membrane Condition
• Faster Future Cleanings

If your roof is holding onto leaves and other debris, contact the Just Leaks team to get a roof cleaning estimate. Give us a call today at 408-249-4646.

When you manage or own a commercial or industrial building, the roofing materials you select can make a big impact on your energy costs, maintenance costs, and more. Just Leaks has been specializing in building, maintaining, and repairing commercial roofs since the 1990s. We have learned a thing or two about roofing materials and which one may be right for your industrial roof. Here are some of the new roofing systems Just Leaks builds for our clients in the San Francisco Bay Area.

AcryPly Polyester Membrane Systems — The AcryPly Systems use Titex polyester roll fabric over the entire roof membrane. The fabric from the polyester roll holds the roof membrane together and gives the roof the flexibility it needs during extreme weather changes. Polyester rolls have the ability to support and help restore roofing membranes, extending the roofs life-span for many additional years.

Spray Polyurethane Foam Systems — Spray Polyurethane Foam (SPF) roofing provides excellent insulation and custom slope to avoid ponded water issues and improve water flow to drainage. SPF roofing systems require a roof coating to be applied over the foam in order to cover and protect the spray polyurethane foam from deteriorating due to the sun’s harmful UV rays. Topcoats are highly reflective, providing longevity and brightness with superior dirt pick up resistance and protection against biological attach such as algae.

Built-up Capsheet Systems — The fire-rated cap sheet roofing system is designed for use as a cap sheet over inorganic and organic built-up roofing systems. It may also be used as a heavy-duty venting type base sheet when installed mineral side down and either mechanically fastened or spot mopped over lightweight insulating concrete decks or existing smooth surfaced membranes.

Metal Panel Roof Systems — We offer a selection of metal roofing panels, both single skin and insulated, that can be utilized in several different industries, including standing seam, concealed fastener and exposed fastener panels.  

Sloped Roof Systems — Sloped roof systems include shingles that have ENERGY STAR® qualified solar reflectance and thermal emissivity requirements. They reflect solar energy and radiates heat far better than traditional roofing shingles, which mean they can reduce the roof’s temperature by as much as 20 percent in the summer.

As you can see, there are many roofing materials that could benefit your flat-roofed commercial building. To determine which roofing materials work best for your needs, budget, and location, contact the Just Leaks team for a consultation. Give us a call at 408-249-4646. We’ll be happy to help.

If you are an experienced roofer, here is what the Just Leaks team is seeking:

3 to 5 years of flat roofing and some carpentry are needed for an industrial flat roofing co. You must perform a wide range of tasks. You must have the following:

• A clean DMV record
• Pass a background check and a drug test
• Have good communication skills
• Be self-motivated and a team player

We will provide your tools, truck, lunch, a friendly work environment and some benefits. Pay is based on ability.

We are an industrial flat roof maintenance and repair company. We mostly do service type work. In the Winter and Spring, we do leak calls. In the Fall, we do maintenance. During Summer, we do whole roofs using cold process built-up, coatings, SPF foam and SA systems. We also have a General Contractor’s license so we can take on anything we want. Our work is very diverse.  We do a bit of carpentry, rot repair, new framing, and structural upgrades.

We are a medium size outfit in San Jose whose workers try hard to work together as a team. We are looking for someone who can hit the ground running. We also want a person who cares about the work he is doing, the company he is working for, and the people he is working with, knowing his care and attention will be reciprocated. We tend to work year round with little down time. You would need to be willing to do whatever is needed at the time, (and there is quite a list). You will not get bored.

If you believe you are a great fit for this position, submit your cover letter and resume to Craig Siemer at craig@justleaks.com.

When a gutter gets clogged, it can cause problems throughout the entire system. The following photos show a recent project, where the Just Leaks team made a difficult integrated gutter repair on a commercial building in the San Francisco Bay Area.

Our team was called because built up debris and defects in the integral gutter system caused leaks in the overhang soffits.

As you can see from the photos below, the built up debris and constant flow of water from condensation deteriorated the metal gutter. The deterioration of the gutter would eventually cause leakage.

The Just Leaks crew began the gutter system repair by removing all debris first. Then, we cleaned and prepped the defective gutter areas. You can see quite a difference in the before and after photos below.

Next, we located the open breaks in the gutter and repaired them.

The repair required us to apply RustEnder anti-oxidizing agent to the metal gutter. Then, we sealed the gutter with urethane and polyester membrane to reduce corrosion.

On this project, our team was happy to repair this integrated gutter system and our client was equally pleased to see no more leaky gutters.

To prevent your commercial building from developing a leak, contact Just Leaks for a complete roof system inspection. To learn more about our roof HVAC installation, roof maintenance, or roof waterproofing services, give us a call at 408-249-4646. We look forward to serving you.

We are proud of the work we do here at Just Leaks, so to kick off 2016 with a bang, we thought we would share photos that highlight the work we do during the rainy season.

This January, we received a call from a commercial property owner with a flat roof that had developed a leak. This is a photo of the leak we found on an exterior wall in the area of a side-wall scupper drain.

This is one of those repairs we are often called out on after several unsuccessful repair attempts have been made by others, or the owners. The roof often deteriorates at the drains due to stress and the drains need to be re-sealed. Here you see the effects of the deterioration at the mouth of the scupper.

What also often happens, and is often not noticed is that there was not enough of a drip edge to stop water from back-flowing at the outer wall. This backflow can go into the building if the leader head clogs, or if the drip edge is not extended far enough into the leader head. If not repaired properly, the leak will continue, even if the drain is sealed at the roof. In the photo below, you’ll see what a complete and reliable leak repair looks like.

These photos show how we removed the old mastic and sealants, rebuilt the roof around and through the scupper, and extended the drip edge. This is an example of how, by having the experience to know what to look for, and by being thorough in investigating all of our leaks, we have a very high success rate in completely stopping leaks.

We realize this article is a bit technical for people who are not roof enthusiasts like we are, but we wanted to clearly illustrate the steps we take when servicing roof leaks. Our years of experience with flat, industrial roofs help commercial property owners secure their buildings against water leaks that could damage the structure, furnishings, electronic equipment, or products located inside the building.

If you are a property owner or business owner that dislikes losing money on their investments and believes in preventive maintenance, you can rest easy knowing that Just Leaks will do a complete and reliable roof repair.
