3 Risky Mistakes in Flat Roof Restoration

Your commercial roof is too valuable an asset to risk. Avoid these three mistakes in low-slope (flat) roof restoration to preserve your roof, safeguard your capital, and keep your business thriving. 

Structure, Then Rooftop

Beneath whatever roofing material covers your business is a roof deck. Never attempt a flat roof restoration without first addressing structural issues underneath the top layers. 

A typical roof has a structural deck, either steel or wood. This is capped with steel or galvalume panels, which are topped with shaped insulation to create the slope. The insulation is then topped with whatever system of roofing you (or the building’s original owner) chose:

  • Modified bitumen
  • PVC
  • EPDM
  • Built-up Roofing (BUR)

If you ignore underlying structural issues from roof deck down to your building’s foundation, no restoration is going to be 100 percent effective. 

Restoration in a Can

Beware the commercial roofer who offers a one-step solution to flat roof restoration. No superficial coating is as effective as a thorough program of restoration, beginning with an inspection and assessment.

Many after-market products exist that are sprayed on or brush applied. These are wonderful solutions to waterproof your roof or prolong its life. But they alone cannot restore a roof that suffers from:

  • Ponding
  • Compressed insulation
  • Neglect
  • Deferred maintenance
  • Clogged drains
  • Water infiltration

Avoid the quick fix and instead invest in a thoughtful program with a local commercial roofer. Such a long-term restoration program will include inspection, documentation, and more:

  1. Spot repair
  2. Cleaning
  3. Waterproofing or reflective coatings
  4. Semi annual inspections and touch-ups

Lifelines

Some property managers view a roof restoration as some kind of magical lifeline to a cheaper, longer-lasting roof. Done correctly, commercial roof restoration rejuvenates a neglected roof, saves money on energy bills, and adds some time to the expensive decision to re-roof. Restoration does not, however, replace conscientious maintenance. 

Throwing a relatively small amount of money at a commercial roof late in its life will never make up for years of neglect. Storms, wind, ultraviolet radiation, heat and annual rainfall all conspire to destroy your roof. One or two visits by a commercial roofer to perform flat roof restoration will never balance against that onslaught. 

Instead, partner with your roofer for the long haul. Get semi annual inspections, arrange for restoration every five or so years, and plan for roof succession. Contact the professionals at Imperial Roofing Contractor today to get an expert’s view on flat roof restoration.
