When it comes to protecting your commercial building, the roof is your first line of defense. But how much do you know about the process behind installing one? Whether you’re replacing an old roof or starting from scratch, a successful commercial roof installation requires careful planning, the right materials, and expert execution. Let’s dive into what it takes to ensure your new roof stands the test of time.
Understanding Commercial Roof Installations: What to Expect
The commercial roof installation process varies depending on whether you’re replacing an old roof or installing a new one. For replacements, the first step is inspecting the roof to decide if repairs are enough or if a complete tear-off is needed. Re-roofing may be possible if the roof is in good condition, but heavy damage requires full removal.
For buildings without a roof, the structure is inspected to ensure it can support the chosen system. Proper insulation is key for regulating temperatures and improving energy efficiency in both new and replacement roofs.
8 Key Steps in the Commercial Roof Installation Process
So, you need a roof installed. Here are the most common steps from before the construction begins to after the last nail is in:
1. Roof Condition Assessment
Before any work begins, a thorough inspection of the existing roof is necessary if you’re replacing an old one. This assessment helps determine whether the current roof can be repaired or if a full tear-off is required. The roof inspector will check for things like leaks, damage to the roof deck, and whether the existing roof materials can support layering a new roof over the old one. If the roof is too damaged or too old, a tear-off will be recommended to prevent future problems.
2. Choosing the Right Roofing Material
Once the roof condition is assessed, the next step is selecting the appropriate roofing material. The choice of material depends on several factors: your budget, the local climate, and the building’s purpose. For instance, TPO, EPDM, and PVC are popular for flat roofs because they are energy-efficient, while slate or metal might be preferred for buildings that need a durable, long-lasting roof. Each material comes with its own pros and cons, so it’s important to choose based on your building’s specific needs.
3. Tear-Off (If Necessary)
If the assessment shows that the existing roof is too damaged, the next step is to tear off the old roofing materials. This involves removing everything down to the roof deck, including old shingles, membranes, insulation, and any damaged sections. A clean, solid deck is crucial for properly installing the new roof. Tear-offs can be labor-intensive and time-consuming, but they ensure your new roof starts on a solid foundation.
4. Roof Deck Preparation
With the old roof removed (or if the current roof can be layered over), the roof deck must be thoroughly inspected and prepared. If the deck has weak spots, water damage, or structural issues, it needs to be repaired or reinforced before moving forward. In some cases, the roof deck may require additional support for heavier materials like slate or green roofing systems. This step ensures the roof has a strong base, which is essential for the long-term durability of the roofing system.
5. Insulation Installation
Insulation is key to energy efficiency, and it can be added or replaced during the roofing process. The right insulation helps regulate the temperature inside the building, keeping it cooler in the summer and warmer in the winter. In addition to comfort, proper insulation can significantly reduce heating and cooling costs. Insulation is installed directly onto the roof deck before the new roofing material is added, and it’s a critical step for both new roofs and replacements.
6. Roofing Installation
The new roofing material is installed once the roof deck is prepped and the insulation is in place. The installation method varies depending on the material you choose:
Precision is key with slate, as improper installation can cause the tiles to crack or shift over time. Each roofing material has its own specific installation process. Still, the goal remains the same: ensuring that the roof is durable, properly sealed, and able to withstand the elements for years to come.
7. Flashing and Sealing
Flashing and sealing are essential for waterproofing your roof. Flashing is installed around areas like chimneys, vents, skylights, and along the edges of the roof. It helps prevent water from seeping into these vulnerable areas. Sealing the seams of the roof, especially on flat or low-slope roofs, ensures that no water can penetrate through gaps. This step is vital for preventing leaks and prolonging the roof’s life.
8. Final Inspection and Cleanup
The final step in the process is a detailed inspection to ensure everything was installed correctly and that the roof is fully watertight. The contractor will check for any potential issues, such as weak spots or areas that might be prone to leaks. The drainage system is also tested to ensure water will flow off the roof properly. After the inspection, the site is cleaned up, and any leftover materials or debris are removed, leaving your new roof ready to protect your building.
Deciding Which Roof Material Works For Your Installation
Before you get too excited about your new roof, let’s discuss some of the different options you have for your next installation:
TPO Roofing
Thermoplastic Polyolefin (TPO) is a single-ply roofing material that’s often white and reflective. It’s lightweight, flexible, and energy-efficient. TPO roofs are good at bouncing sunlight away, which helps keep buildings cooler and saves on energy bills. It also resists mold, dirt, and punctures, making it durable.
One issue with TPO is that not all brands or installers offer the same quality. The seams where pieces of the material are joined together can sometimes leak if not installed properly. Additionally, because it’s a newer roofing material, long-term performance varies depending on the installer.
EPDM Roofing
EPDM (Ethylene Propylene Diene Terpolymer) is a synthetic rubber roofing material that’s commonly used on flat roofs. It’s well-known for being affordable and durable, lasting up to 30 years with minimal maintenance. It handles bad weather well, and even the sun doesn’t wear it down easily. EPDM comes in black or white, with black being a common choice, though white is available for cooler climates.
The black version of EPDM absorbs heat, which can make buildings hotter and increase cooling costs. It’s also more vulnerable to punctures from things like sharp objects or heavy foot traffic, so repairs might be necessary over time.
PVC Roofing
PVC (Polyvinyl Chloride) is a strong single-ply roofing material that’s flexible and resistant to chemicals, oils, and harsh weather. It’s great for buildings where chemicals are present, like restaurants or factories. PVC is also reflective, helping to lower energy bills by keeping the building cooler. It holds up well under foot traffic and is long-lasting.
PVC roofs can be more expensive than TPO or EPDM, making them less budget-friendly. Over time, the material may become brittle and more likely to crack, especially in colder climates. Repairs might be needed as the roof ages.
Slate Roofing
Slate is a natural stone material used for roofing, and it’s known for its beautiful, high-end appearance. It’s also extremely durable, lasting up to 100 years or more. Slate is fire-resistant, which adds to its safety benefits. Plus, its natural look can enhance the overall value of a building.
Slate is very heavy, so the roof structure needs to be strong enough to support its weight. This may require reinforcing the building, which can add to the cost. Also, while it’s tough, slate can crack if someone walks on it or heavy objects fall on it, making maintenance tricky.
Metal Roofing
Metal roofing is made from materials like aluminum, steel, or copper. It’s one of the longest-lasting types of roofing, often lasting 40 to 70 years. Metal roofs reflect sunlight, helping to lower energy costs. They’re also fire-resistant and environmentally friendly since many are made from recycled materials.
Metal roofs can be noisy during heavy rain or hail unless extra soundproofing measures are taken. They also expand and contract with temperature changes, which can put stress on the fasteners. While metal roofs have a higher upfront cost, they can pay off in the long run due to their long lifespan.
Green Roofing
Green roofs, or living roofs, are covered with plants and vegetation. They help absorb rainwater, reduce urban heat, and even improve air quality. Green roofs also provide natural insulation, keeping the building warmer in winter and cooler in summer. They look great and bring a touch of nature to urban environments.
Green roofs require regular maintenance, like watering and taking care of the plants. Installing a green roof is also more expensive upfront because of the extra layers needed, like drainage systems and root barriers. Additionally, the building must be able to support the weight of the soil and plants.
Has your business been trying to go green, but you aren’t sure about a green roof solution? Take a look at how your new roof can boost your energy efficiency without necessarily being covered in plants.
Pre-Installation Preparations for Commercial Roofing
It’s important to prepare the site and roof properly before starting the commercial roof installation process. These steps ensure that the new roofing system will last as long as possible and perform well.
Site Inspection and Roof Condition Assessment
Start by inspecting the roof to make sure it’s in good condition for the new roofing system. This includes checking for leaks, cracks, or damage to the roof structure. The slope and drainage system should also be evaluated to make sure water will flow off the roof properly, avoiding future water damage.
Necessary Repairs and Modifications
Any damage to the roof, like cracks in the deck or weak spots in the insulation, should be fixed before installing the new roof. If you’re installing heavier materials like slate or a green roof, the roof structure may need reinforcement to support the added weight. It’s also important to check that the drainage system is working properly, and if not, add more drains or gutters.
Weather and Timing Considerations
Plan the roof installation for a time when the weather is clear and dry. Some materials, like TPO or EPDM, need specific conditions to be installed correctly, so avoiding rain or extreme temperatures is important. Preparing for weather changes during the installation can also help avoid delays and mistakes.
