How long should a commercial roof last?

The upkeep and replacement of a structure’s commercial roofing is an enormous responsibility and a huge expensive. Just like the roof on a residence, roof repair for commercial building protects the structure, the occupants, and everything inside, including machinery and inventory.   

Just like a residential roof repair or replacement, commercial roof repair cost is something the owner of the building is concerned with too. Before they replace their commercial roofing, the owner should have an inspection by a contractor to determine if a commercial roofing repair cost and the ROI is sufficient. 

There are three key types membrane materials used the most on commercial roofing, which are typically flat. With proper maintenance and upkeep, these materials can give commercial roofing a lifespan up to fifty years. Those three types of membrane materials are:

  • EPDM – a synthetic rubber material with the longest history of commercial roofing membrane materials. It is the least expensive, easy to work with, and has a lifespan up to thirty years with proper maintenance and upkeep.
  • PVC – this membrane material is the most expensive of the three commercial roofing costs we’re focusing on in this piece. It is the most energy efficient with a white color that gives it high UV resistance. With proper maintenance and upkeep, this commercial roofing membrane materials has a lifespan up to twenty years.
  • TPO – a single-ply commercial roofing material that is applied in one of three ways:
    • Mechanically Fastened
    • Fully Adhered
    • Ballasted

Where PVC commercial roofing material has plasticizers, EPDM does not, making this commercial roofing material more environmentally friendly and stronger seams. Less expensive than the PVC commercial roofing material and has an expected lifespan of twenty years when maintained properly.

What are the signs of a bad roof?     

Commercial roofing systems are an integral role in protecting the structure underneath from the climate and elements. Commercial roofing is extraordinarily complex with several individual components. Each component needs to be kept in good condition to ensure the best performance of protection. 

Regular, thorough inspections are important for commercial roofing by the maintenance crew or building manager. These inspections should be focused on a close assessment of the roof’s condition, and any abnormalities should be immediately addressed.  The smallest issue can grow into an expensive and large problem quickly. 

Some of the roofing issues that need to be addressed by a professional commercial roofing contractor are: 

  1. Ponding: This occurs when there is blockage or poor drainage on the flat roof. When water can’t drain from the flat commercial roofing, it begins to pool and pond. This pooling and ponding, combined with constant exposure to the UV rays, is it accelerates the start of structural failure and the commercial roof aging.   
  2. Ceiling: When you notice condensation or water stains on the ceiling isn’t always necessary does not always mean commercial roof leak repair is required, but it should be a concern a professional should investigate that. The moisture could be from an HVAC issue or plumbing issue. Building maintenance crew should attempt to locate the source then call the proper professional. 
  3. Rot: Commonly found in areas that are restricted or unused and have got to the point of rot because of this. When an area isn’t occupied or used, small issues go undetected and get worse over time. A routine commercial roofing inspection should include looking in these restricted and unused areas for possible rot. 
  4. Mildew and Mold: Moisture problems lead to mildew and mold. Any time a commercial roofing inspection find mildew or mold, further inspection should be performed to find the source of the mildew, then the problem addressed promptly. 
  5. Neglect, Wear and Tear: Commercial roofing will have a high level of wear and tear, which is why regular inspection is needed. When the inspections aren’t performed, the wear and tear will lead to neglect of the roof. We recommend inspections after a storm to check for possible storm damage and schedule emergency commercial roof repair

What is the best time to replace roof?      

For commercial roofing replacement, spring is the ideal time for replacement when the weather isn’t freezing or extremely hot.  During moderate temperatures, the contractor can work faster and get the job done faster. Less labor time makes a less expensive roof replacement. Another point in favor of springtime for commercial roofing replacement is it often still slow from winter downtime, so getting on the schedule is easier.
