Roof Maintenance Plan

Preventive Maintenance:

All member roofs are to be walked on a rotating schedule quarterly to inspect and repair the following:

  • Cap flashings.
  • Edge metal.
  • Base flashings.
  • Penetrations.
  • Field of the roof.
  • Clean roof drain systems.
  • Remove any organic debris.
  • Roof adhesives; and Surface coatings, if present.
  • Keep roof clean and free of debris.


Cap flashings, which are metal or other rigid covers at membrane terminations, should be inspected for:

  • Loose areas of attachment or loose or missing fasteners;
  • Loose or displaced sections of metal;
  • Deformed metal that could collect water and funnel it through an end joint;
  • Corrosion;
  • Missing or loose joint covers;
  • Sealants showing signs of cracking, weather and/or aging.

Edge metal, installed at the edge of a roofing system to terminate the roof and provide waterproof flashing, should be checked for:

  • Loose areas of attachment or loose or missing fasteners;
  • Loose or missing stripped-in flashing;
  • Splits in the stripping at metal flashing joints;
  • Corroded metal;
  • Missing or displaced metal sections or joint covers;
  • Open joints and sealants displaying signs of cracking or weathering or aging. • Check and repair termination bars.

Base flashings, which are roof membrane terminations at walls and curbs, should then be looked at. Watch for:

  • A secure and sealed top termination;
  • Continuous adhesion of base flashing to substrate, with no loose membrane or extensive bridging;
  • A covered top seal of the membrane base flashing;
  • Closed seams at the bottom of the base flashing at its attachment to the field membrane;
  • Sealed seams at vertical laps;
  • Sealants in good condition, without signs of cracking, weathering or aging; and
  • Base flashing material without signs of deterioration or building movements.

Penetrations are pipes, drains and other items that are inserted through the roof membrane. They must be flashed properly to assure a watertight roof. An inspector should examine the following:

  • The drain clamping ring and drain strainer to ensure they are properly secured for a watertight seal at the membrane-to-drain interface;
  • Thorough adhesion of sealant inside pitch pockets and membrane adhesion around the outside of pitch pockets;
  • Pitch pockets containing adequate fill material to prevent water from collecting; • Pipe boot flanges sealed tightly to the roof membrane;
  • A tight seal and termination around pipe(s) at the top of pipe boots.
  • Replace missing drain baskets.

In the field of the roof, be sure that:

  • No fasteners protrude against the membrane, causing a “tenting” effect; or that there are no visibly loose fastening points;
  • The membrane contains no worn spots, deteriorated areas, or holes in the membrane;
  • Insulation panels are in their original positions; no buckling or warping,
  • There are no changes in insulation or substrate firmness when the roof is walked on;
  • Adequate drainage is present;
  • Around rooftop equipment, no areas have been degraded by equipment leaks or spills, or have been punctured by dropped tools or equipment parts from workers maintaining roof mounted equipment. Content below:

Condition Review:

Management will work with crews to facilitate a roof assessment report for the all members roofs which may include:

  • Total square footage and layout.
  • Materials assessment through core analysis.
  • Life expectancy.
  • Roofing types and materials.
  • Replacement or service life extension recommendations.
  • Thermal scans which show water infiltration of the roofing system.
