10 Steps You Need For Your Commercial Roof Maintenance

10 Steps You Need For Your Commercial Roof Maintenance

Clearing your To-Do list is every building owner’s goal every day, but with commercial roofs, most commercial property owners simply don’t know what to watch for, and what to ignore. Consider these 10 hot tips for dealing with commercial roof maintenance

1: Guestbook

Record the name, title, and purpose of every visitor to your facility’s roof. Restrict access so people cannot climb up without supervision, or without good reason. 

Workers’ boots can scrape away ballast, tear into single-ply membrane, or kick out flashing. Third-party workers obviously need access to items like radio masts, HVAC units, window-washing equipment, and signage. Yet these workers also need monitoring. Keeping a running record of roof access preserves your roof assets. 

2: Visual Triage

When you safely walk your low-slope commercial roof, perform a visual triage of every item you inspect:

  1. Good — No action by your facilities crew or your dependable, local commercial roofer is needed now
  2. Fair — A condition is developing which requires careful monitoring, but no further action at this time
  3. Bad — Immediate attention, repair, and correction is needed

For every item marked “Fair” or “Bad,” record where it is situated on your roof, take pictures or video, and jot notes on the exact concerns you have. Then use this information when working with your local commercial roofing contractor, so nothing is overlooked. 

3: Pack a Bag

Keep a rooftop access toolkit on hand. Use it when walking the roof by yourself, or when working with your roofing contractor. Essential items to include:

  • Component checklist
  • Pad and pencil for taking notes
  • Camera or cell phone for taking pictures
  • Roof plans or aerial photos
  • A tape measure
  • An LED flashlight for dark areas

4: Walled Up

Less dangerous than a rooftop excursion is an inspection of your building interior. Look at your walls, especially those closest to the roof deck. Do you see telltale signs roof problems are developing?

  • Signs of mold or mildew
  • Dark spots
  • Peeling paint or wallpaper
  • Dampness 
  • Crumbling drywall

Look higher than the walls; are drywall or drop ceilings showing stains, discoloration, or active water leaks? All of this information will help your roofer determine a course of remediation. 

5: Damp Spots

Damp areas around vents, chimneys, roof projections, or exterior walls generally indicate rooftop problems. Feel the walls. You can also apply a moisture meter if you feel the investment is worthwhile.

Exterior walls are prone to leaks between roof fields and flashings. Chimneys and roof piercings can leak if flashing or caulking fails. 

6: Airing Your Problems

Good ventilation throughout your building is key to a healthy roof. Does your roof deck itself have proper ventilation? If you can see into the deck, do you see sagging decking, cracks in wood rafters and structural supports, or corrosion in steel? 

Can you see light streaming in from the roof, inside the roof deck? Does the air smell fresh or musty? Can you see mold or mildew on any surface? 

Adequate roof ventilation gives your environmental systems a break; interior, treated air has to be both the right temperature and humidity for human comfort. Roof deck air should closely match the outside air. 

7: Leaks

Record as much information as you can about existing leaks, from tiny drips to raging torrents. Your roofer needs to know where the leaks appear inside the building and if any damage on the roof is visible. 

Avoid asking your untrained facilities crew to try to solve roof leaks. Especially in low-slope structures, an open seam on one part of the roof could be causing a leak inside the building 50 feet away. 

8: Three Ds

If you can safely walk your roof, look for visible and obvious signs of damage, deterioration, and debris. 

  • Damaged roofs never mend themselves. Note the extent of the damage and its location
  • Deterioration is normal but may accelerate due to deferred maintenance or outright neglect
  • Debris can clog exterior scuppers or internal drains; blocked gutters and downspouts lead to leaks

9: Wear & Tear

On the roof, safely inspect flashings, chimneys, vents, fascia, drip edges, HVAC curbs, and other structures. Look for wear and tear, corrosion, rot, or rust. Note every issue for your commercial roofer’s reference

10: Poke & Prod

On low-slope or flat roofing, if you feel comfortable and conditions allow, look for ponding (depressed areas accumulating water), holes, blisters, crazing or tears in membrane, and separation between roof and material. 

Test seams; inspect mechanical fasteners for elongated holes indicating thermal expansion and contraction. Note any issues for your roofer.
