The Importance of Periodic Roof Inspections

Roofing systems should be inspected at least twice a year (Spring and Fall) for damage or defects. Someone who understands the design and components of the roofing system should perform inspections. Your BASF approved applicator may provide this service.

The Spring roof inspection identifies any damage sustained over the Winter so repairs can be accomplished during the local roofing season. The Fall roof inspection will make sure the roof is ready for the upcoming Winter. Seasonal inspections are important for both warm and cold weather regions.

Each inspection should follow a set routine for the examination of each visible component of the roof assembly and the identification of any areas requiring attention. Pay particular attention to:


Gutters, Scuppers and Drains

• Leaves, dirt, etc. can block positive drainage • Seals • Screens and strainersContent goes here

Rooftop Units and Penetrations

• Vents, hatches, stacks, skylights and HVAC equipment • Condensation from HVAC units piped to drains • Rain caps on stacks • Seams in units • Damage to the surrounding roof system caused by service to units

Surface Area of Roof

• Mechanical or physical damage caused by tools or heavy objects, hail, vandalism or excessive foot traffic • Blisters or interlayer separation

Flashings, Roof Edges, Terminations, Expansion and Control Joints

• Cracks or splits at roof terminations, including edge flashings and expansion joints • Coping joints and metal flashings • Check masonry walls for moisture penetration or deterioration

Special Inspections

Special inspections are recommended following situations such as: • Construction on or above the roof or adjacent areas • Installation of new equipment on the roof • Extreme weather conditions such as hail, high winds or unusually heavy snow load • Fire, vandalism or other known damage to the roof or adjacent areas An inspection should also be carried out when maintenance, repair or re-roofing is anticipated. A follow up inspection should be performed when this work is completed.


• Pinholes • Erosion of coating or SPF • Cracks and moisture penetration • A small slit sample may be taken to determine moisture content, or a non-destructive detection device may be used

Prevent Damage

Take these steps to prevent damage and safeguard the long life of your ELASTOSPRAY SPF roofing system: • Remove debris from the roof • Do not use the roof as a storage area • Vent exhaust or harmful chemicals away from the roof surface • Pipe condensation from HVAC units to drains • Minimize foot traffic or install walkways to reach essential area equipment (check with BASF or your approved applicator prior to installation)

Know Your Roof System

Keep a historical record and roof system file available to all roof maintenance personnel. The file should include.

• Technical data sheets
• Material safety data sheets
• Original specifications
• Warranty
• Contact information for your approved applicator
• Previous roof inspection reports
• Record of repairs made
• Copy of this manual

When to call an Approved Applicator

Some repairs will require an approved applicator’s expertise. Consult warranty terms before performing any repairs to avoid negating the warranty. The warrantor must be notified prior to performing repairs to any problems covered by the warranty. Other situations that require a professional include:
• Large blisters
• Significant leaks
• Renewal/recoating


The service life of a spray polyurethane foam (SPF) roof can be greatly extended by proper maintenance and care. The building owner should:

• Limit and control roof access
• Conduct regular inspections
• Conduct special inspections following extraordinary situations such as extreme weather
• Report leaks or damage immediately
• Perform routine maintenance
• Use approved applicators for major maintenance, new penetrations and permanent repairs

Paying attention to these six areas will help to provide the building with a sustainable, high performance, longer life expectancy, lower lifecycle cost roof.
