Types of Commercial Roofing Services We Offer

We provide numerous commercial roofing solutions and services to our commercial clients, no matter the size of your project.

Our name is our best asset, so we’ll never sell you something you don’t need – and its what makes us the most reliable contractor in the county. If you’ve got a leak or a damaged area, we’ll assess the problem, fix it, and do whatever we can to make sure it doesn’t happen again, including recommendations for preventative measures you can take to avoid problems in the future.

Commercial Roof Replacement

Roof failure, leaks, old and neglected materials, or a recently purchased building that needs upgrades are all reasons why a roof might need to be replaced. Commercial roof replacement may be required when installing an A/C unit, a plumbing stack, an exhaust vent, a skylight, or additions to increase your building’s energy efficiency. Depending on the condition of your roof or other needed work being done, a full or partial roof replacement may be required.

We understand that a new roof is a significant expense for your company which is why we will always work to provide the most economical and smartest solution. We also know that eventually maintenance efforts will fail and a new roof will be required for your business.

That’s why we’ll collaborate with you to choose the best solution for your needs once that time arrives. After that, we’ll make sure it’s expertly installed and successfully built to last for a long time.

Commercial Roof Repair and Maintenance

By the time we see a leak manifest, there’s a large amount of damage done that has gone unseen. You might be surprised to know that many roofing contractors won’t repair commercial roofs. They’re only looking for big contract replacements and may even tell you that a minor repair requires a replacement because that’s how they make the most money from you.

Roof Repairs are a great solution if a full installation or replacement is not necessary. When commercial roof repair makes the most sense, we’ll work with you to outline our approach and timeline to ensure your expectations are met with the least amount of disruption to your business and fix the problem areas to extend the life of your current roofing solution.

Common Commercial Roof Issues:

  • Leaking & Ponding Water
  • Open Seams
  • Punctures
  • Blow Off from Extreme Weather
  • Shrinkage
  • Splitting & Ridging
  • Hail & Storm Damage
  • Weathering

Keeping roof drains free of debris is an important and often neglected maintenance item. In fact, it is perhaps one of the most important flat roof maintenance items, since its neglect could lead to an array of serious problems that would require repairs. If a roof drain becomes clogged, water will pond on the roof. Ponding water is extremely problematic as it can seep into flashing seams and freeze, weakening the seams. Because 90% of all flat roof leaks occur at the flashings, repairs to the lap seams in the base flashings often need to be made.

Flat & Pitched Commercial Roofing

ROI Construction has experience with a variety of commercial roof slopes from mild to steep slope roofing; each has its challenges, and each requires an individual approach to the roofing materials selected. If you have a steep slope or pitched roof or a combination commercial project, we can help you find the right materials for your business and your budget. Our Maryland service location will be happy to provide a free estimate for any of your commercial roofing needs.

Our Most Popular Commercial Roofing Materials

Thermoplastic Polyolefin is a single-ply roofing membrane that is a popular choice for low slope roofs. Despite plastic being in its name it is actually a blend of polypropylene and ethylene-propylene rubber. TPO is available in a bright white material which can reflect UV rays and heat away from the building potentially saving you money during hot summer months! Most commonly, TPO Roofing Systems are applied on commercial or industrial roofs especially in the Baltimore and DC areas.

Ethylene Propylene Diene Terpolymer is commonly referred to as rolled rubber roofing. It’s durability and longevity is due to its composition make up of recycled tires, slate dust, and sawdust. It can be easily coated to match a desired color of your choice and is a cost efficient material to help protect your commercial roof.

A Polyvinyl Chloride roofing system is a thermoplastic membrane that is best known for its flexibility. The American Society of Testing Materials (ASTM) requires any roofing membrane to have a minimum breaking strength of 200 pounds per inch and PVC far exceeds this standard as it has a minimum breaking strength of 350 pounds per inch. It is recommended especially for buildings containing restaurants or near airports due its resistance to chemicals and animal fats that could arise from grease vents.
