this is an exellent company
Response from the owner: Thank you so much, Md. Leyon. We really appreciate you taking a moment to say that.
Second part, hope you read the first. Now we get into the real work … Mike was the manager in charge, he was also very polite and got us on schedule right away. He alway ‘s communicated with us daily. When they came out first thing they did was cover the bushes everything around the house even the pool ( we were worried about the pool). They were on time, did their jobs and cleaned up afterwords. Never had any problems and they put up with my husband hanging around them asking questions checking it all out. My husband says this is an A+ company, a job well done. It may cost a little more but you get what you pay for….
Response from the owner: Thank you, Jackie, for taking the time to write both parts. We'll make sure Mike hears how much his daily updates meant, and we're glad the crew's care with the bushes and the pool put your minds at ease. Please tell your husband his questions were always welcome, and his A+ means a lot to the whole team.
Cobex delivered a first rate experience from the initial meeting until the end. Excellent experience
Response from the owner: Thank you, Todd. We're glad the experience held up from that first meeting all the way to the finish.
We had a great experience working with this company. They were professional, knowledgeable, and took the time to answer our questions and explain everything thoroughly. Their communication was excellent, and we really appreciated their honesty, responsiveness, and attention to detail. It was a pleasure working with them.
Response from the owner: Lisa, thank you for the kind words. Honest answers and clear communication are what we aim for on every job, and we're glad that came through for you.
From Julian who I spoke to initially to Luis who ran the crew that installed and of course the crew that installed my roof this experience was smooth and painless. Julian understood that I was not interested in up sales. He also promised to schedule within 2-3 weeks. He delivered. Luis and the guys where helpful and answered all my questions with patience. Thank you Cobex.
Response from the owner: Thank you, Alfonso. We're glad Julian kept the conversation focused on what you actually needed and hit that 2–3 week scheduling window, and we'll let Luis and his crew know their patience with your questions didn't go unnoticed. Enjoy the new roof.
I really appreciate Mark's thorough assessment of my roof and siding and his honest presentation of my job. He answered all my questions and provided good information to help me make a decision. Thanks, Mark!
Response from the owner: Thank you so much for your wonderful feedback! We're delighted that Mark could assist you and offer valuable insights. Your satisfaction is really important to us, and we're always here to help!

Best experience ever with having a roof installed very happy with product and cleanliness of job site

Your happiness with our work means the world to us. If you ever need anything else, don’t hesitate to let us know!
Mark is amazing, came out early and explained everything to me and was very honest, taking his time to thoroughly explain every detail. This experience alone gives me confidence to use them forever!
Response from the owner: Your glowing review made our day! 😊 It's wonderful to know you had such a detailed and honest experience with Mark. We're committed to being your trusted choice for the long haul. If there's ever anything else we can assist you with, please reach out!
I had a wonderful experience working with Mark, with his promptness calling ahead of time and showing up ahead of time. I would highly recommend this company if you need a new roof or anything exterior.
Response from the owner: We truly appreciate your kind words and recommendation! It's fantastic to hear that you enjoyed working with our team, especially Mark's punctuality. We're so happy to have been part of your project. If you ever need anything else for your home, we're here to help!
Cobex was professional from start to finish. I received quotes from other firms but the estimate I received from Cobex was very thorough so I had a lot of confidence that they were providing a complete project price with no surprises. And there were no surprises. The crews were professional, efficient, and kept the property clean. Vasiliy was great to work with. He was on top of every detail and highly responsive to any of my inquiries. I also like that Cobex was able to perform repairs beyond the roof replacement on the eves and facia making the project with a single contractor rather than having to coordinate with multiple. I fully recommend Cobex.
Response from the owner: Thank you for the thoughtful review, Jay! We’re glad Vasiliy and the team made the entire process clear and straightforward, from the detailed estimate to the roof, eaves, and fascia work. We truly appreciate your recommendation!

Great experience here with Cobex. Had 3 different estimates, they had the best price. Once we started the process everything went smooth and fast! The crews that did the work were relentless, and I mean that in a good way. On time, professional and friendly...plus they even cleaned up everything when job was complete. Highly recommend *****

Our team's dedication shines through your remarks, and we're thrilled you were pleased with their work ethic and professionalism. Thank you for recommending us and for choosing Cobex. 😊
For the past 6 months I’ve been gathering estimates for our roof installation and met several estimators. I want to give a shout out to Mark Shpyrka for taking the time to explain the entire process of getting a new roof and welcomed every single question I had. He treated me (and our property!) with respect and was very understanding about my project timeline and resources. I’m grateful for what I learned and the refreshing experience to work with a knowledgeable estimator invested in a great customer experience.
Response from the owner: We're so happy to hear that Mark made your roofing process so informative and respectful! It’s wonderful knowing you felt supported and your needs were truly understood. Your kind words about the experience mean the world to us. 😊 Thanks a ton for trusting us!

Cobex Construction Group was the last company that the General Manager David Leal came to my house to show me waht they can offer, and it was exactly what I needed a company that can do everything for their customers. I didn't have to shop around for repairs and painting work, they did the Roofing, the siding repairs and painting, and they also removed and reinstall the solar panels.I'm really happy with the work done, that I highly recommend this company for your home future projects. Thank you and God bless.

I helped my parents choose this company for their roof replacement, and I'm very glad we did. The team was honest, easy to work with, and kept me updated throughout the project. One thing I really appreciated was how patient and accommodating they were despite the language barrier. They even had someone who could speak with my parents directly, which made the entire process so much easier for them (and me). Everything was completed exactly as promised, the workmanship was excellent, and my parents are extremely happy with the final result.
Response from the owner: Thank you so much, Sophie! It truly means a lot that you took the time to share your family's experience. We know how important clear communication is during a project like a roof replacement, so we're especially glad you felt informed every step of the way.We're also proud to have both Spanish- and Russian-speaking team members available because we believe every homeowner deserves to feel comfortable, understood, and confident throughout the process. Knowing that this made the experience easier for your parents is incredibly rewarding to hear.Thank you again for trusting us with your family's home. We hope they enjoy their new roof for many years to come!
The project went well and service lived up to what we were expecting.
Response from the owner: Thank you! We're so glad to hear everything went as expected and that you were happy with both the service and the final result. We appreciate you trusting us with your roof and taking the time to leave a review.

After getting a few estimates, we chose this company for our roofing and siding project, and it was absolutely the right decision. The crew worked hard and delivered exactly what they promised. Great experience from start to finish.
Response from the owner: Thanks, Dmitriy! Hearing that you felt you made the right decision is exactly what we strive for. We appreciate you taking the time to leave a review.
From the initial consultation through the final walkthrough, everything was handled professionally. Had my roof and siding replaced, and the attention to detail was impressive. It's hard to find a contractor that communicates this well. The team kept me informed every step of the way, showed up when they said they would, and followed through on everything they promised. The new roof and siding completely changed the look of our home. I would gladly hire them again for future projects.
Response from the owner: Thanks, Amanda! We really appreciate you taking the time to share your experience.
The crew was very professional and addressed all of my concerns. I’m very happy with how my full roof replacement turned out, it’s perfect. Highly recommend.

FAMILY

Cobex Construction Group is a family-owned business committed to treating you like family. Our concierge service ensures regular communication throughout your project. We provide transparent communication, trusted advice, and the best value for your home investment. Treating you like family isn’t just a business decision—it’s who we are.

FREEDOM

Freedom is our core value at Cobex. Founded by Vazgen, son of immigrants seeking freedom, we express this through quality workmanship and professionalism. Every day, we celebrate the opportunity to serve our community and customers with commitment and compassion, never taking our freedom or ability to make a difference for granted.

FAITH

Cobex is founded on faith, guiding our commitment to integrity and transparency. Initially a general contracting business, we focused on exterior services as we grew. Our faith-based values drive our dedication to quality, craftsmanship, and honesty.

Roofing Services for Cool Homes

We do exterior work, and roofing is where we lead. Our approach to roofing services here is repair-first and replace-when-right: we document what we find, show you the photos, and let the roof’s actual condition drive the decision. That focus on one category, done thoroughly, is a choice we made on purpose. For Cool’s mix of older development-era homes and newer construction, it means a scope matched to your house instead of a sales script, whatever your roofing needs.

Roof inspections identify a roof leak and deterioration before they reach the interior. Our residential roofing repairs address storm damage, failed flashing, and ordinary wear, and we also handle storm damage repairs after a hard season. Replacements are the honest call when repeated repairs no longer protect the home. As a roofing company we serve both residential and commercial properties, and our professional roofing services and roofing solutions are matched to each building rather than sold off a shelf.

Roof Repair

Roof repair covers leaks, flashing failures, roof penetrations, and worn areas before winter rain turns a small weakness into interior damage. Not every roof needs replacing, and a repair documented with photos keeps your investment protected without over-scoping the job. A single roof leak caught early is far less costly than the water damage it causes when ignored. Because roof repair costs vary with the damage, we quote in writing rather than guess. See our main roofing services for the full range.

Roof Replacement & Roof Installation

Roof replacement becomes the responsible choice when repairs are no longer practical. Our roof installation covers the full system: underlayment, ventilation, a roof decking review, and new covering. A complete roof replacement means the entire roof is addressed, not patched around. The repair-versus-replace call is made in writing, backed by date-stamped photos, so you understand exactly why we’re recommending what we are. Done once, done right, means a new roof installation that holds up for the long term.

Roof Inspections

Our photo-based roof inspections catch early damage and document the roof’s current condition. You get a clear record of worn flashing, aging underlayment, and vulnerable valleys, which is the honest starting point for any decision. Regular roof inspections also help you track wear and catch issues before they escalate. Small problems left alone affect roof performance and shorten the life of the whole assembly.

Roofing Materials and Owens Corning Systems We Install

We install asphalt composition shingles, tile, metal, and low-slope roofing systems, matched to your property rather than a single default. The appropriate roofing system depends on slope, exposure, and the look you want. Among our materials, we install Owens Corning shingles and their Total Roofing Protection System, a layered assembly built to perform over time. Asphalt shingles typically last about 20 to 30 years, while tile roofs and metal roofing systems can last significantly longer. For homeowners wanting durable alternatives, stone coated steel and other metal roofing hold up well against sun and wind. We focus on durable, lifetime-quality products rather than the cheapest option on the shelf.

Commercial Roofing and Commercial Properties

We also handle commercial roofing for local buildings, including low-slope membrane systems. Our commercial roofing services cover inspection, repair, and replacement for commercial buildings and mixed-use structures. It isn’t our main focus, but the capability is here when a Cool business needs commercial roofing systems that protect the space below. Whether residential or other commercial buildings, the standard of workmanship stays the same.

Why Cool Homeowners Choose Cobex Construction Group

Why Cool Homeowners Choose Cobex Construction Group

We know how Cool actually permits and builds. Reroofs here go through the El Dorado County Planning and Building Department, Building Division, not a city office, because Cool is unincorporated. We handle the county documentation, coordinate inspections, and plan for the gated entries and sloped, multi-acre lots common around here. Our confirmed office sits at 2281 Lava Ridge Ct, STE 200, Roseville, CA 95661, roughly 23 road miles out, close enough to show up and know the terrain. We also serve nearby communities in Placer County and across El Dorado County, including Granite Bay, Rocklin, Granite Bay, El Dorado Hills, and Fair Oaks, so the crews that work your roof already know this region.

On the questions that matter most to a homeowner comparing roofing contractors, here’s the evidence. We hold CSLB License #1031864, which you can verify, and we carry general liability and workers’ compensation coverage, so an accident on your property doesn’t land on you. General liability for a roofer should sit at $1 million or more. Verifying a contractor’s state license is one of the clearest ways to avoid scams and poor workmanship, and California enforces strict contractor law.

We’re BBB accredited since December 15, 2017, and family-owned, which is why communication is built in rather than promised. Homeowners around here tell us their neighbors constantly compliment the finished work, and that kind of superior customer service is the reputation we’ve earned. Your roofing project runs through defined roles, a project manager, a superintendent, and a Client Success Manager, so you’re never chasing an update. Alongside manufacturer coverage, a separate workmanship warranty of 5 to 10 years is the standard a reliable roofing company should offer. Talk with us and check the credentials yourself.

How Your Cool Roofing Project Works

How Your Cool Roofing Project Works

Your project moves through clear stages, from first call to final inspection. A written contract detailing the scope comes before any work starts, and collecting multiple estimates is a reasonable step we welcome. When homeowners describe hiring a prior contractor and getting a roof replaced that never held up, we understand the caution, and our outstanding customer service and installation quality are built to answer it.

  • Inspection and written scope: photo-documented, with the repair-or-replace reasoning spelled out.
  • Material selection: roofing materials matched to your property and your budget.
  • Permit submission: we confirm and submit the county’s Part 9 residential reroof application when it’s in our scope.
  • Delivery and site prep: staging, protection, and access planned in advance.
  • Tear-off and sheathing review: El Dorado County requires a roof-sheathing inspection before new roofing covers the deck, so any soft or damaged decking we find is documented and approved before we proceed.
  • Installation and final inspection: the county’s final building inspection closes out the permit.

The county’s Roof Verification Certificate, certifying a Class A assembly, is kept available for the inspector at final. Because decking discoveries are documented as we go, there are no surprises buried in the covering. We describe the timeline in stages rather than a fixed number of days, since a full tear-off depends on weather windows and what the deck reveals.

Roofing in Cool Permits, Property and Climate in El Dorado County

Roofing in Cool: Permits, Property and Climate in El Dorado County

Cool’s roofing realities come down to the county, the terrain, and the seasons. Cool is an unincorporated community in El Dorado County, and county permit records show the county issuing roof-replacement permits for Cool addresses, including work on Overton Road, Ranch Creek Road, and Indian Rock Road. The Building Division operates from 2850 Fairlane Court, Placerville. The county runs a roof-sheathing inspection and a final building inspection, and the Roof Verification Certificate must certify a Class A assembly available at final. That Class A requirement matters where fire exposure is a concern, though every parcel’s actual CAL FIRE hazard designation should be confirmed by address, not assumed community-wide.

The housing stock here is varied. Auburn Lake Trails properties use Cool mailing addresses and include established homes from the 1980s and 1990s through newer construction from 2019 and 2023, on streets like American River Trail, Secret Lake Trail, Sweetwater Trail, Cascade Trail, and Strap Miner Trail. Individual Cool lots range from compact parcels to multi-acre properties with variable or downslope terrain, and that variable terrain can affect roof performance and how we place ladders, trucks, and material pallets. Landmarks like Cool Community Church on Cave Valley Road anchor the area.

Climate drives the scheduling. Hot, dry summers put sustained UV on shingles, seal strips, and sealants, while rain concentrates in the cooler months. Worn flashing and aging underlayment, plus failing vent pipes, are what let winter rain in, and an aging roof only gets more vulnerable each season. If a reroof changes to a heavier material such as concrete tile, county guidance calls for structural information on the existing roof, and properly installed tile needs that structural review first. We work from our Roseville office, about 23 road miles from Cool, and plan each job around reliable dry windows so an open deck isn’t caught in a storm.

Frequently Asked Questions

Do I need a permit to replace my roof in Cool, and who pulls it?

Yes, reroofs require a permit from El Dorado County, and we confirm and submit the Part 9 residential reroof application when it’s in our scope, then coordinate the sheathing and final inspections. Cool is unincorporated, so the county Building Division, not a city department, is the authority. A written scope ties the permit responsibility to the contract before work starts.

How much does a roof replacement cost in Cool?

Roof prices depend on roof size, pitch, material, access, existing layers, decking condition, ventilation, and any solar removal, so we don’t publish a flat figure or a one-size percentage rule. The honest way to know your number is a free inspection and written quote. We’re glad for you to compare estimates, and financing is available if you want quality with payment flexibility.

How long does a roof replacement take in Cool?

We describe the timeline in stages rather than promise a fixed number of days: inspection, material selection, permit, delivery and prep, tear-off and sheathing review, installation, then final inspection and cleanup. Winter rain and dry-window scheduling can shift dates on a full tear-off.

Can your crews get into Auburn Lake Trails or up a steep, gated driveway?

Yes, we plan gate entry, delivery vehicle size, pallet placement, driveway protection, and debris staging before work begins, which matters on Cool’s sloped and multi-acre lots. Where a property owners association governs access, we coordinate that too.

What roof is best for a wooded or wildfire-exposed Cool property?

Confirm your parcel’s actual CAL FIRE hazard designation by address, then install a Class A roof assembly, which the county’s Roof Verification Certificate requires certified at final inspection. We also inspect vents, edges, valleys, and debris-collection points where embers gather.

Can you reroof a house that already has solar, and will you help with insurance?

Yes, we coordinate solar removal and reinstallation within the written scope so penetrations are resealed properly. For storm damage, we can document the roof condition and help you navigate the repair or replacement process with your homeowner’s insurance when applicable; coverage and approval remain with your insurer.
