Idea Behind The MK Best Roofing
MK Best Roofing was built on real experience, not shortcuts. Owner Mynor Lopez began his roofing journey at a young age, learning the trade hands-on as an apprentice. From the beginning, he was taught the correct way to install a roofing system, focusing on structure, durability, and long-term performance. After two years of installing roofs in the field, his dedication and skill earned him a promotion to manager. Over the next several years, Mynor continued to refine his knowledge of roofing systems, leadership, and quality control. After five years in the industry, he decided to start his own company—MK Best Roofing—with one clear goal: to deliver roofing done the proper way. Quality materials and workmanship were non-negotiable. To support this standard, the company partnered with GAF, providing top-tier shingles and industry-leading warranty coverage for homeowners who expect lasting results.

Types of Roofs We Specialize In
Residential Roofing Services
Commercial Roofing Services
01 – Personalized Consultation & Site Understanding
Residential:
We begin every residential flat roofing project with a detailed inspection of your existing roof. Our team checks for moisture damage, weak decking, drainage issues, and structural concerns to ensure a solid foundation. Once evaluated, we prepare the surface by removing damaged materials and cleaning the area thoroughly. Proper preparation allows us to create a smooth base for installation and ensures your new flat roofing system performs reliably for years to come.
Commercial:
For commercial properties, we conduct a comprehensive assessment of the roof structure, insulation condition, and drainage systems. Large surface areas require careful planning to prevent future pooling or structural stress. We coordinate with property managers to minimize disruption to business operations. After evaluation, we prepare the roof deck by addressing any damaged sections and ensuring the surface is clean, secure, and ready for a professional flat roofing system installation.
Step 2 – ISO Insulation with Brackets & Screws
Residential:
For residential flat roofs, we install high-quality ISO insulation using brackets and screws to ensure maximum stability and energy efficiency. This method helps regulate indoor temperatures and strengthens the overall roofing system. Properly fastening the insulation prevents shifting and enhances durability. Our attention to detail during this stage ensures your home benefits from improved comfort, reduced energy costs, and a roofing system designed for long-term performance.
Commercial:
In commercial flat roofing projects, ISO insulation is installed with heavy-duty brackets and screws to provide strong attachment across large roof areas. This secure fastening method enhances structural integrity and energy efficiency, which is especially important for commercial buildings. Proper insulation also supports long-term durability and performance under varying weather conditions. We ensure every section is evenly secured to create a stable and reliable base for the roofing layers.
03 – Clear Inspection Report & Visual Evidence
Residential:
Once insulation is secured, we install the flat roofing system using two layers of base coat followed by one layer of cap sheet. This three-layer system provides superior waterproofing and durability for residential properties. The double base coat strengthens protection against leaks, while the cap sheet adds an extra shield against weather exposure. This layered approach ensures your home’s flat roof remains strong, secure, and long-lasting.
Commercial:
For commercial properties, we apply two layers of base coat and one cap sheet to create a durable, high-performance roofing membrane. This multi-layer system is designed to handle heavy exposure, foot traffic, and weather changes. The reinforced base coats add strength, while the cap sheet provides top-level protection and waterproofing. This method ensures commercial buildings receive a flat roofing solution built for long-term reliability and performance.
04 – Practical Repair Guidance & Future Planning
Residential:
After installation, we carefully seal all seams, edges, and flashing areas to prevent leaks. Our team conducts a final quality inspection to ensure the two base coats and cap sheet are properly applied and securely bonded. We check drainage flow and overall surface finish before project completion. This final step guarantees your residential flat roof meets our quality standards and provides dependable protection for your home.
Commercial:
For commercial flat roofs, we complete detailed seam sealing and flashing reinforcement to ensure full waterproof protection. A final inspection is performed to confirm the ISO insulation is properly secured with brackets and screws and that all roofing layers are correctly installed. We verify drainage performance and overall structural integrity before finishing. This thorough process ensures your commercial property receives a durable and professionally completed flat roofing system.

Benefits of Flat Roofing
- Cost-Effectiveness: Flat roofs generally require fewer materials than pitched roofs, resulting in lower construction and installation costs. This cost efficiency extends to repairs and maintenance as well, making flat roofs a financially savvy option over time.
- Space Utilization: The flat surface allows for the use of rooftop space for various purposes, such as gardens, patios, or solar panel installations. This additional usable area can enhance property value and provide functional outdoor spaces.
- Easier Maintenance: Flat roofs provide easier access for inspections and repairs due to their level surface. This accessibility simplifies routine maintenance tasks, reducing the risk of accidents during upkeep.
- Energy Efficiency: With appropriate insulation and reflective materials, flat roofs can improve energy efficiency by reducing heat absorption. This is particularly beneficial in warmer climates, leading to lower energy bills.
- Faster Installation: The straightforward design of flat roofs allows for quicker installation compared to pitched roofs. This means less disruption for homeowners or businesses during construction.
- Modern Aesthetic: Flat roofs align well with contemporary architectural styles, offering a clean and minimalist look that appeals to many property owners.

Reviews
Outstanding roofing and repair work! The crew was knowledgeable, efficient, and respectful. They finished the job on time and delivered excellent results. The entire process was stress-free, and the pricing was reasonable. Highly recommend their roofing repair services.
Izzy and team were a pleasure to work with. They did a great job with removal and reinstallation of my solar panels after a full roof replacement and skylight installation. They also worked diligently to resolve a small hiccup (that I inadvertently caused) on the day of install. Everything looks great! I have no complaints, just appreciation for their problem solving and top notch customer service. I would recommend MK Best Roofing to anyone - and already have done so.
Exceptional workmanship and attention to detail. The team was respectful of our property and left everything spotless. Wouldn’t hesitate to recommend them!
Very satisfied with their work! The team explained every step of the process and made sure everything was done perfectly. Our home feels brand new again.
I’m blown away by the results. They replaced my old shingles and the difference is huge. Friendly staff, smooth process, and top-tier craftsmanship.
Hired MK Roofing for roof service. They came in time gave me a great and fair price for the job. All work completed on time and in a professional manor. Would highly recomand their company and their amazing team.
MK Best Roofing truly lives up to their name! The team was professional, efficient, and went above and beyond to make sure everything was perfect. They explained every step of the process, finished on schedule, and the quality of the work speaks for itself.
This has to be the best experience I’ve had! I went with their crew after a few companies gave me estimates. Izzy was so knowledgable and took his time to explain the entire job!
Great partner for our new roof start to finish. MK Best was super transparent in sharing all the materials and offered great pricing. The project was finished in a day and the team came back twice for some small fixes. Would highly recommend MK Best!
We hired MK Best Roofing to replace our old roof. We were so impressed we just had them do our gutters too! From the initial quote to the final cleanup, Izzy and his team is fantastic. They are professional, incredibly efficient, and the quality of their work is outstanding. Both our roof and gutter projects were completed faster than we expected, and each crew was respectful and tidy. Izzy made sure we received our warranty so that we have complete peace of mind with our home exterior. Truly the best in business!
In my search for a new roof I contacted 3 roofing contractors out of the local penny saver. They were all legitimate and didn't have any outstanding complaints against them. Each contractor brought something different to the table with varying products and prices. After weighing the many choices I decided to hire a roof inspector to help me sort everything out. Max at Atlantic Independent recommended MK Best Roofing as my best option as they are a top certified contractor with high quality products. MK was not part of my original search but I am glad I chose them. They installed a new roof, new attic fan, new gutters and replaced two existing skylights. I was very pleased with my dealings with Izzy at MK and he made sure that I was satisfied with the entire project. I can recommend MK Best Roofing without hesitation.
