What Should You Look for in a Roofing Contractor?

When you need service on your commercial roof or a new roof altogether, how do you look for a contractor to meet your needs? Hiring a commercial roofing contractor can seem daunting if you don’t know what virtues to demand.

 Unless you have gone through some of the terrible things that can occur when you make a hasty, easy choice, you likely won’t know what kind of qualifications and measures you need for your contractor. Here are six things every business should look into when hiring a roofing contractor:

 How long have they been in business? There’s tension in repair contractors between having years of experience and the most recent training. If they’re just getting started, will they have the experience to know what kind of issues your roof is facing?

  1. Do they have the most recent training in equipment? A seasoned organization will have a better grip of your issues, but are they a bit anachronistic– can they take you forward into new technology? Your business needs a contractor that knows a lot and grows into new technology and craft.
  2. What’s their reputation? It’s essential to know what kind of local reputation a potential contractor has. Ask for examples of previous clients they are free to disclose to find out how the business feels about their work and the warrantied work they are still receiving to this day.
  3. What’s covered in an estimate… and what isn’t? There shouldn’t be ambivalence in a quote for work to be done. In any situation where you request a quote for specific work, the contractor should look through all the details and be very specific about your money and the labor that it will take to accomplish the task. Nothing should be vague or left to chance.
  4. Are they on the up-and-up? Do they have the proper coverage– are they licensed and insured? You might get a great price quote from a small independent, but if they have no accident coverage and no intention of fixing errors they cause in the course of the job, what good are they to your business?
  5. What can they do to save my company money? Are they working in the kind of materials that can provide maximum efficiency? Can they set you up with solar collectors to reduce your power costs?

  Just Leaks in San Jose, CA can tick all of these boxes. Our experienced roofers are constantly training and improving, with a stellar reputation. Our standing in the community comes from our being a licensed, insured outfit. We have a world of options to save you money over the years and help pay for the work we’re doing.

Signs You Need a New Roof

We often don’t look up above our eyeline to see what’s going on in the world. But commercial roofers often look up. Standing on roofs, we can look over and see other businesses in need of repair. We see the damage to commercial buildings when we stand on an even level. Most of the people inside these commercial buildings will never know that their roof is in need of repair or replacement until they feel something fall or drip onto their heads. 

Here are some of the indicators that your commercial roof may be in need of rebuilding:

  • Curled shingles
  • Cracks in the shingles or the surface
  • Vegetation (weeds, moss, grass)
  • Patches of missing gravel
  • Bubbling
  • Missing shingles
  • Dark streaks
  • The roof is 20 years or older

If you encounter these and other symptoms, it might be time to start planning for a new roof, before weather and time catch up to your business. We can help you work out how much you’ll need to set aside and find the least disruptive time to begin the work.

And if your business is not taking advantage of solar initiatives, consider investing now, when your roof can begin to pay for itself over the first five years in savings. Just Leaks has over 40 years of experience in solar panel installation. We work with top tech firms, with clients all over the bay area. We install everything ourselves and we guarantee performance!

How Mother Nature Can Affect Your Roofing System

Rough weather is nearly upon us! With Summer in full swing, and Fall and Winter up next, it is important to be prepared for the next weather rolling in. In this blog, we will look ahead to how weather can affect your roofing system.

When you are outside and are caught by unpleasant weather, your first instinct may be to seek shelter in your dry and warm home. This works great, however, until you notice raindrops coming through the ceiling! Mother nature is full of surprises, and it’s best to keep your roofing in check to avoid any possible disasters in the future. Here we will list how mother nature affects your roofing system, so you know what to keep an eye for to prevent further damage from occurring.


The leading contributor to roof damage is rain. With long periods of rain, water can find the tiniest cracks or holes in your shingles and will seep through, causing rot, mold, and mildew. It is essential to look for water spots in your ceiling as this can be a clear sign that water is not getting deflected by your roof as it should.


Although not as common as rain, hail is still something that can cause heavy damage to your roof. Depending on the size and weight of the hail, the damage caused can lead to cracking and wearing down of your shingles. You can count on Just Leaks to look at your roof after hail to inspect and assess any damage caused. 


Several elements of mother nature can cause your gutter to get clogged. It is essential to have your gutters cleaned as failure to do so can cause flooding, algae and moss, and further roof damage. We recommend having your gutters cleaned at least twice a year.


Light winds will not cause much damage, if any at all, to your roof. However, high winds that usually come from storms can cause uplifting and ripping of your shingles. The heavy wind can cause vulnerability for rain and snow as the water would easily slip through the cracks.

Whether you noticed damage or leaking yourself or experienced any of the weather events above and want an inspection made, Just Leaks in San Jose, CA, will offer exceptional and professional work that will surely leave you feeling satisfied and relieved from any worry.

CA Solar Bill of Rights

The CA Solar Bill of Rights is as good as it sounds. California is proving again and again that our state is the best state for both clean and solar energy innovation. In fact, all new homes built in 2020 onward must have be installed with solar panels. This bill changes the game for both residential and commercial industries in three main ways:

No more unfair fees: Solar owners now have guaranteed, fundamental rights to self-generate and store renewable energy with discriminatory fees.
Faster service: All California utility companies are required to follow a state-mandated, more efficient process for connecting new solar arrays to the grid.
Better compensation: Home batteries will receive fair compensation for exporting power to the grid and ensuring a community of solar power efficiency.

Overall, the CA Solar Bill of Rights emphasizes that no matter where in California you live, how much money you make, what industry your business operates in, you should have access and the ability to save money and help save the planet by the use of solar panels. For more information about the Bill of Rights, to learn more about solar panels, and for an estimate about installing solar panels on your commercial or industrial roofing system, please give us a call at (408) 249-4646.

Spring Cleaning for Your Roofing System!

With winter behind us, your commercial roof is most likely in need of a little TLC. And the team at Just Leaks is here to help, experts in industrial and commercial roofs in San Jose and Bay Area especially after all the rain the Bay area has experienced this season. It is easy to remember to spring clean your home, but you can’t forget about your roofing system. Here are a few tips and tricks for spring cleaning for your industrial or commercial roof:

  • A healthy gutter means a healthy roofing system. Clogged or weak gutters can lead to water overflow, which could make your roofing system susceptible to damage.
  • Don’t forget about the trees around your property. If the trees are getting dangerously close to your roofing system, they could be scraping and causing damage to your industrial or commercial roof.
  • Moss, mold, and dirt, oh my! This debris can compromise the materials of your roofing system, so a roofing expert should take a look to ensure your entire roofing system is not compromised.
  • After the winter weather, there could be weak spots in your roofing system, and before April rains hit us, it would be smart for a roofing expert to examine your roof for any worn or damaged areas in your roofing system.
  • There can also be moisture accumulation under the roof covering, and our team can check for any loose material or wear around the pipes.

Overall, our best recommendation is to have a qualified roofing expert to examine your roofing system. Winter can take a toll on your industrial and commercial roofing system, and before you are faced with a potentially dangerous or expensive problem, we encourage you to contact us for a complimentary roofing estimate. Please give us a call at (408) 249-4646.

Trees, Moss, and Algae, Oh My! Stuff That Endangers Your Roof

It starts off when you notice something unusual growing on your commercial and industrial roofing system. Upon closer inspection, you realize it is something from Mother Nature. This situation is a very common scenario, as at times, trees, moss, and algae can wreak havoc on the roof of your commercial building.


  1. Moss: In more humid and rainy weather, moss tends to grow on rooftops. Most of home and business owners will ignore this green mess, until it starts to ruin the appearance of your property. While it doesn’t immediately damage your roofing system, it does hold in moisture, which can result in expensive repairs in the long-run. It’s important to get rid of this green nuisance before it’s too late.
  2. Algae: Similar to moss, algae is attracted to wet and humid areas. It’s not as harmful as moss, but it still can cause problems and should be taken care of. THe amount of algae accumulating on your roof can depend on the sunlight exposure.
  3. Trees: Trees bring a myriad of problems, as fallen overhanging branches to leaves and pine needles can create an issue. Don’t forget about your gutters too, as leaves and pine needles are especially prone to get in this area.


Either way, from trees to algae, our team at Just Leaks will thoroughly examine your roofing system for any signs of disarray. If we notice too much moss, leaves and pine needles, or algae, we will quickly eliminate the problem.


One of the ways we can get ahead of Mother Nature is to provide annual inspections and repairs. For most of the industrial and commercial buildings in the Bay Area – we have found that a single roof maintenance call during Autumn before the rainy season is extremely effective in minimizing the frequency and severity of roof leaks, moss, algae, and trees. Similarly, we find that industrial roof inspections performed in the Spring allow us to service and repair roofs that have withstood storm damage, collection of debris, and water pooling.


If you want to remove unnecessary roof hazards from your commercial property, schedule an appointment for an inspection, call Just Leaks at (408) 249-4646.
