- Roof Installation Process
- The two major types of composition reroofing projects are 1) Wood Shake to Composition Conversion and 2) Composition to Composition Reroofing. The procedure for each type of reroofing is explained below.
- Permits and Inspections
- Permits and Inspections - The requirements for permits and inspections vary by type of reroof and vary by city. Most cities have building inspectors that inspect various stages of the roof removal and roof installation to ensure the work is to code.
- Dry Rot - Any wood in the roof that is damaged due to dry rot must be replaced to pass city inspections and building codes. Dry rot in the eaves can often be observed during the initial roof measurement and can be included in the proposal. However, dry rot that is under the old roof may not be observable until after the old roof is removed. In such cases, Kerr Roofing will discuss the issue with the homeowner when the dry rot is exposed, and Kerr Roofing will replace the dry rot for the cost of the additional material and labor.
- Tear-off Inspection - An inspection done after the old roof has been removed.
- Decking Inspection - An inspection done after OSB (Oriented Strand Board) has been installed. Also known as a Nailing Inspection.
- Final Inspection - An inspection done after the roof is completed.
- Homeowner Preparations
- Garage - Homeowner should cover items in the garage (e.g. washer and dryer) and remove vehicles from the garage so that dust and debris falling through the openings in the roof do not collect on or scratch valuables. Kerr Roofing can assist the homeowner with tarps if requested.
- Driveway - Homeowner should remove vehicles from the driveway so that a Kerr Roofing dump truck or dumpster has access to the house to facilitate the roof removal.
- Solar Panels - If solar panels are present, homeowner should disconnect water from solar panels. Kerr Roofing can remove and 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 the reroof.
- Satellite Dishes & Antennas - If dishes and/or antennas are present, homeowner should arrange for a technician to disconnect and remove them from the roof. If the dishes & antennas are not removed, Kerr Roofing will take reasonable precautions to remove and reattach them to the roof. However, Kerr Roofing does not have the expertise to install and/or align antennas or satellite dishes. Kerr Roofing makes no warranties about the proper functioning of the antennas or satellite dishes after the roof installation.
