Roofing Installation Process

Permits and Inspections

The two most common roofing projects are; 1) wood shake to composition shingle conversion and 2) composition shingle re-roofing. Once a contract is signed, Tri-City Roofing is fully responsible for all permits and inspections that will be required during the project. The requirements for permits and inspections can vary by type of project and by city. Most cities have building inspectors that inspect various stages of the roof removal and installation processes to ensure the work is completed to code.

Dry Rot Damage

Any wood in the roof that is damaged due to dry rot must be replaced to pass city inspections and building codes. Before starting the project some dry rot damage may be apparent and will be included in the original proposal. However, dry rot that is under the old roof may not be detectable until the old roof is removed. In such cases, Tri-City Roofing will discuss the issue with the homeowner when the dry rot is exposed. Tri-City Roofing takes a non-profit approach to any wood replacement that is required due to dry rot. Since Tri-City Roofing only charges for labor and materials, the cost impact to the homeowner if additional dry rot damage must be repaired, is minimized.

Homeowner Preparation

Prior to starting a roofing project, the homeowner is responsible for the removal of solar panels, satellite dishes and antennas as described below. In addition, the following precautionary tasks are suggested to minimize the impact on the homeowner’s property while the work is being performed.

Solar Panel Removal
If solar panels are present, homeowners should disconnect water from the panels. Tri-City Roofing can discard old solar panels if requested. If solar panels are to be reused, homeowner should make arrangements with a licensed contractor to remove the solar panels prior to roof removal.

Satellite Dish and Antenna Removal
If dishes and/or antennas are present, homeowner should arrange for a technician to disconnect and remove from the roof. If the dishes & antennas are not removed, Tri-City Roofing will take reasonable precautions to remove and reattach them to the roof. Tri-City Roofing does not have the expertise to install and or align antennas or satellite dishes. Tri-City Roofing provides no warranties about proper functioning of the antennas or satellite dishes after the roof installation.

Garage and Driveway Preparation
Homeowners and tenants should cover items in the garage (e.g. washer, dryer, etc) and remove any vehicles from the garage so that dust and debris falling through the openings in the roof do not collect on or scratch valuables. Tri-City Roofing can assist the homeowner/tenant with tarps if requested. Homeowner/tenant also must remove vehicles from the driveway so a Tri-City Roofing dump truck has access to the house to facilitate the roof removal.

Roof Removal and Installation Process

The following steps are taken during a roofing project.

  1. A Tri-City Roofing dump truck is parked adjacent to the home and a Tri-City Roofing tear off crew removes the old roof and loads the debris into the dump truck. Depending on the size of the roof and the number of layers, the roof removal generally takes several hours. If new gutters are to be installed, we will remove the old gutters.
  2. Replace any wood that is damaged due to dry rot.
  3. City Building Inspector performs tear-off inspection.
  4. Prime and paint any wood that was replaced due to dry rot.
  5. If a shake roof is being replaced by a composition roof, OBS sheets are laid over the skip sheathing to provide a base for the shingles. City Building Inspector performs a decking inspection.
  6. Apply 15 or 30 lb. felt to provide moisture barrier.
  7. Replace any damaged flashings and install vents. The number and location of vents is determined by the size and shape of the roof.
  8. Install shingles.
  9. Install aluminum or steel gutters (if ordered).
  10. Cleanup job site by removing any and all roofing debris.
  11. City Building Inspector performs the final roof inspection for city code sign off. Tri-City Roofing will be leave a ladder at the job site for the city Inspector to use. Tri-City Roofing will retrieve the ladder from the job site after the final inspection is completed.
