How can I make my roof last longer?

To get the most of your commercial roof, preventative maintenance is a must. Any commercial building manager or commercial building owner should have a commercial roof maintenance plan with a commercial roof maintenance checklist, making sure that they follow them each week, month, all year as stated. Commercial roof maintenance is necessary in order to catch any issue before it becomes a costly expense and interruptive process. 

Commercial roofing professionals advise that while some roofing materials last longer than others, the lifespan of any roof is based on averages. Here are some commercial roof maintenance tips that will help you get the best and longest performance from your roof. 

Suitable design

Years are added to the life of a commercial building’s roof when the building and the roof have a suitable design. From proper sizing structural members and careful consideration of penetration details to selecting the right roof type at the start of a construction project is a must, followed up by consistent and proper commercial roof maintenance.

Adequate ventilation

Just as the roof on your home needs proper ventilation, so does a commercial building’s roof. The roof level needs good air flow to stay cool in the summer and warm in the winter. Proper ventilation prevents moisture build-up and eliminates mold. An experienced commercial building HVAC engineer and technician will ensure the air flow is adequate during an annual inspection, which should be a part of your own commercial roof maintenance plan.

Routine maintenance

Too often, building maintenance is taken for granted, but when it comes to commercial roof maintenance, that should never be ignored. Every commercial building should have a roof that is accessible so that the organization of the HVAC and plumbing systems is kept up and any roof repairs are addressed promptly.

The material and method

There are as many commercial roof types as there are ways to perform commercial roof maintenance. It can be confusing to choose the right roof type. The climate, the location, and the cost should all be carefully considered. For a flat roof application, the BUR (built-up roofs) makes good sense for regions with little rain.  Today, sustainability is a driving force for energy savings and ROI over the roof’s lifetime. Commercial building owners should take advantage of sustainability incentives in making their commercial roof decisions.

Choose a reputable commercial roofing company to work with so you know you’re getting the best.

  • Cleanliness: While on the rooftop doing an inspection, look for an accumulation of dirt and debris and remove them. These will clog roof drains, cause ponding, which will decay or rot the roof. Remove any tree limbs and check for a possible roof membrane damage. If trees are a constant problem, schedule a tree trimming service.
  • Roof Surface: During your commercial roof maintenance inspection, check for damage or weathering, like the low spot on a flat roof, where water is notorious for collecting. Look for blistering, cracking, deep scratches, holes, or tears in the membrane. For a gravel-top roof, make sure the gravel is uniformly layered and free of empty spots. For commercial metal roofs, your commercial roof maintenance inspection should include looking for corrosion and damaged or loose panels.
