Commercial Roof Maintenance Program

Interior of the building.

• We examine the interior walls and ceiling for any signs of moisture or water penetration. ​

Visual inspection of the roof.​​

Cap flashing inspection.

• Full inspection and repair for loose / missing fasteners.​

• Deformed metal.

• Loose or displaced sections of metal. 

• Corrosion.

• Missing or loose joint covers. 

• Sealant showing signs of cracking, weathering, or ageing.

Edge metal inspection.

• Loose areas of attachment.​

• Loose or missing stripped-in flashing.

• Splits in the stripping at metal.

• Corroded metal.

• Sealant showing signs of cracking, weathering, or ageing.

Base flashing inspection.

• Verifying a secure and sealed top termination.​

• Verify a continous adhesion of base flashing to substrate.

• Verify a covered top seal of the membrane base flashing.

• Verify closed seams at the bottom of the base flashing. 

• Verify sealed seams at the vertical laps. 

• Verify sealants are in good condition, without signs of cracking, weathering, or ageing. 

Penetration Inspection

• Inspect the drain clamping ring and drain strainer to ensure proper securement for a watertight seal. ​

• Verify thorough adhesion of sealant inside the pitch pockets and membrane adhesion. 

• Verify pitch pockets contain adequate fill material to prevent water from collecting. 

• Verify pipe boot flanges sealed tightly to room membrane. 

• Verify a tight seal and termination around pipe(s) at the top of the pipe boots. 

Inspection of the Field of the Roof

• Inspect to verify no fasteners are protruding against the membrane, causing a "tenting" effect. ​

• 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 the insulation or substrate firmness when the roof is walked on. 

• Adequate draining is present. 

• Inspect any rooftop equipment to verify no roofing areas have been degraded by equipment leaks or spills. 

Roof Clean-Up

• Pick up any loose debris like paper, bottles, broken glass, tree limbs, vegetation and dispose of it properly. ​

• Remove obstructions such as leaves and twigs, from roof drains and scuppers, to ensure proper drainage.
