Roofing RepairsROOF INSPECTION & MAINTENANCE ROOF REPAIR

Modern roofing systems contain a wide variety of components and installation techniques. All roof inspections should be conducted by a licensed roofing contractor or similar roofing professional. Typically, two inspections should be conducted each year, one in the spring and one in the late fall. If the roof is warranted, at least one roof inspection each year should be conducted by the licensed contractor who originally installed the roof. Please note that the cost of periodic inspection is typically not included in the original cost of a manufacturer’s warranty. Accordingly, the building owner should contact a licensed contractor to obtain a proposal for ongoing inspection and maintenance services.

All roofs require periodic inspection and maintenance in order to perform as designed and to provide a long and effective service life. Periodic inspection and maintenance is also typically required by roofing system manufacturers to keep roofing warranties in full force and effect. Although all building owners should establish a periodic roof inspection program, inspection and maintenance of any roof should be undertaken only by qualified persons who are familiar with safe roofing practices, including all applicable occupational, health and safety regulations relating to the roofing and construction industries.

Wind storms can damage roofing systems in several different ways. The effect of the wind itself can exert a force on important roof system attachments that prevent the roof system from separating from the roof deck and building. Wind forces can also damage exposed sheet metal items, such as gutters and downspouts. In addition, the force of the wind-borne debris may cause puncture or cutting of the roof membrane. In fact, severe wind storms can even dislodge rooftop units and cause the units to blow across the roof, causing extensive roof membrane damage. WHEN TO LOOK: As soon as possible after any significant wind storm.

WHERE TO LOOK:

  1. Roof Membrane Surface.
  2. Rooftop Units.
  3. Roof Edge Metal, Gutters & Downspouts.

WHAT TO LOOK FOR:

  1. Displaced ballast.
  2. Shuffled or displaced insulation boards beneath the roof membrane.
  3. Loose or missing sheet metal flashing components and shingles.
  4. Loose roofing fasterners and plates
  5. Large cuts or slices in the roof membrane
  6. Loose or disbanded areas of roof membrane
  7. Distortion of any roofing membrane

ROOF REPAIR RECOMMENDATIONS

REMEDIAL ACTIONS:

  1. Remove Debris.
  2. Replace or Re-Disperse Roofing Ballast. This must be done carefully in order to avoid puncturing the membrane.
  3. Repair Damaged Roof Membrane & Components. Permanent repairs should always be performed by a licensed roofing contractor. In order to respond to emergency situations, the following actions can be taken by the building maintenance staff:
  • Small cuts and punctures can be sealed temporarily.
  • If large areas of membrane have become detached and are actively billowing, it is very important to cut the membrane to reduce the internal pressure build-up. Even though this procedure may cause some water to enter the roof system, it may prevent additional detachment of the membrane and the potential for a roof “blowoff”.
  • Roof membrane which has detached at the perimeter anchorages should be resecured by weighting the membrane with sand bags or by securing with a wood batten or secure by proper roof nailing.

PREVENTIVE ACTIONS:

  1. Add Roof Ballast. If some areas of ballast stone are frequently displaced by winds, consider adding a larger size of ballast stone or replacing ballast stone with concrete pavers. Note: Ballast should not be added to a roof without a review of the roof load capacity by a structural engineer.
  2. Replace or Re-Disperse Roofing Ballast. This must be done carefully in order to avoid puncturing the membrane. Or contact your roofing company to do the roof repair.

INTRODUCTION: Standing water can cause problems for both asphalt and single-ply roofing systems. Because asphalt compounds are not inherently resistant to the sun’s rays, most modified bitumen and built-up roofing membranes use a layer of factory-applied granules, a field-applied liquid coating or a layer of roofing gravel to protect the membrane from ultraviolet degradation.

A small cut or puncture in the roof membrane may cause little damage on a well-drained roof surface, but the same puncture located in an impacted drainage area can produce extensive damage to the roof insulation, roof deck and building contents. Although effective roof drainage can be achieved through a variety of methods, all roofs should be designed and maintained to provide a consistent and effective path for water to completely drain off and away from the roof surface within 24 to 48 hours of a rain storm. Effective drainage must also accommodate build-ups of snow and ice that may typically occur during winter months .

Under constant exposure to standing water, however, granule and gravel coatings will tend to wash off and liquid coatings may blister and peel. Once this important coating is removed, the underlying asphalt membrane may begin to degrade due to direct exposure to sunlight. Although single-ply roof membranes provide excellent resistance to water and sunlight, the potential for damage to the roof is also significant when water is allowed to stand on a roof.

WHERE TO LOOK:

  1. Large Rooftop Units. Heavy rooftop units can frequently cause deck deflection and create a ponding area around the unit.
  2. Mid-Span Of Roof Beams And Joists. Because most horizontal structural members deflect in the center of the span, ponded areas are located frequently along the mid-span of these framing members.
  3. Roof Drainage Components. Typical roof drainage components include: a) roof drains, b) wall scuppers, c) gutters & downspouts.

WHAT TO LOOK FOR:

Although improper roof drainage can best be observed immediately after a rain storm, most impacted drainage conditions will leave “tell-tale” indications even after standing water has evaporated:

  1. Visible Sagging or Deflection.
  2. Accumulated Debris. Debris frequently accumulates in ponding areas. Because water eventually evaporates from impacted areas, a concentric pattern of debris or dirt is a good indication of a ponding condition.
  3. Damage To Drainage Components.
  4. Discoloration of Curbs and Walls. The discoloration may be due to a build-up of snow or ice, or it may be an indication that water may “back up” during very severe rain storms.
