Roofing Services

 

Our Process

The National Roofig Contractors Association recommends that a roof assembly be designed only after a number of criteria have been carefully considered, including:

  • Climate and geographic .ocation
  • A buildings intended use and design life expectancy
  • Code Requirements
  • Type of roof deck
  • Slope and drainage
  • Roof's configuration
  • Building Movement
  • Fire, wind, and Inpact resistance
  • Type and amount of insulation needed
  • Need for ventilation
  • Maintenance, repair and reroofing
  • Compatibility with adjacent components, including potential material discharge onto a roof
  • Construction sequencing
  • Worker Safety
  • Potential building additions
  • Odors, noise and dust generated by certain system application methods
  • Rooftop traffic

These criteria play important roles in the ultimate success or failure or a roof assembly and should be considered by a designer to determine the appropriate components of a roof assembly and the applicable specifications and construction details to be used.  In addition, a designer should be certain that the roofing manufacturers' requirements are taken into account.  It is prudent to consult manufacturers' written specifications during the design of a roof assembly. 

 

Most of our roofing services consist of a six-step process:  staging, demolition, preparation, new roofing material application, clean-up and disposal.

  1. Staging consists of essential planning and scheduling of people and materials.
  2. Demolition includes the removal of all existing layers of shingle materials, roof vents, flashing and drip edge.
  3. Preparation consists of removal of all nails and staples in the decking from prior shingle installation. The decking will then be blown and swept down prior to any installation of new materials.
  4. New roofing material application commences with installation of all new drip edge, felt, pipe flashings, and step flashings.  The shingle material, vents, counter flashing and valleys will be installed per manufacturer specifications.
  5. Clean-Up will be completed daily and includes sweeping of walks and drives, running of a roofer’s nail magnet along the perimeter of the home and driveway, cleaning of gutters and removal of debris from the roof area.
    Disposal is the final step and will be handled in a legal manner by a reputable sanitation company.

 

Regular Inspection and Maintenance

Regular maintenance is a necessary part of good roofing practice and a roof system should be maintained by performing periodic maintenance and repairs as necessary.  A good maintenance program is the owner's responsibility and the greatest assurance of long-term roof system performance and value.  Culbertson, Inc. would be pleased to assist in the preparation of an owner's maintenance program.  We would like to make the following suggestions:

  • Inspect the roof at least twice yearly, preferably in the spring and fall.
  • Inspect all roofs after severe weather or storms.
  • Make frequent inspections on buildings that house manufacturing facilities that evacuate or exhaust debris on to the roof.
  • Clean debris from all roof drains.
  • Remove leaves, twigs, cans, balls, etc, which could plug roof drains.
  • Bag and remove all debris from the roof because debris left on the roof surface may be swept towards a drain and may clog drains.
  • Notify the roofing contractor immediately after a roof leak occurs.
  • Note conditions resulting in leakage.  Heavy or light rain, wind direction, temperature, and the time of year that the leak occurs are all important facts that help to trace roof leaks.
  • Note whether the leak stops shortly after each rain or continues to drip until the roof is dry.  All associated facts enable the diagnosis and repair of roof problems to proceed more rapidly.
  • Do not allow foot traffic on the roof in very cold or very hot weather because damage may result.
  • Do not allow the installation of television or radio antennas, satellite dishes, mechanical equipment or other roof penetrations wihout notifying Culbertson, Inc., and membrane manufacturer if the roof is under a manufacturer's warranty, and consulting with them about the methods and details for these installations.
