The project begins with a thorough inspection of the existing roof to identify any underlying structural issues, areas of water damage, or ventilation problems. This assessment helps in determining the extent of the tear-off required and whether additional repairs or modifications to the roof structure are needed before the new installation.
Preparation
Tear-off: The first step involves removing all existing roofing materials down to the roof deck. This includes the dismantling of shingles, underlayment, flashing, and any other components of the previous roof layers.
Deck Inspection: Once the old materials are removed, the wooden decking is inspected for damage, rot, or mold. Any compromised sections are marked for replacement.
Site Protection: Measures are taken to protect the home’s exterior, landscaping, and surrounding areas from debris. This often involves the use of tarps and strategically placed dumpsters.
Installation of New Plywood Decking
Decking Replacement: Damaged or rotten decking sections identified during the inspection are removed and replaced with new plywood sheets. This ensures a solid, uniform base for the new roofing materials.
Preparation for Installation: The entire roof deck is then prepared for the installation of the new roofing system. This includes ensuring that the surface is clean, dry, and free of any debris or nails.
New 2-Ply Flat Roof System Installation
Base Sheet Installation: A high-quality base sheet is rolled out and attached to the plywood decking, serving as the first layer of defense against water penetration. The base sheet is typically fastened with roofing nails or adhered using a bonding agent, depending on the system specifications.
Cap Sheet Installation: The second ply, or cap sheet, is then installed over the base sheet. The cap sheet is often a granulated layer that provides the final waterproofing barrier and UV protection. It is applied using a torch-down method, cold adhesives, or self-adhering methods to ensure a secure bond between the layers.
Flashing and Edging: Metal flashing is installed around the roof perimeter, chimneys, vent pipes, and other protrusions to prevent water entry. The edging is secured to ensure that water flows off the roof correctly.
Finishing Touches
Inspection and Cleanup: A final inspection is conducted to ensure the installation meets all local building codes and manufacturer specifications. The site is then cleaned up, removing all debris and materials.
15-Year Workmanship Warranty
Warranty Coverage: The project includes a 15-year workmanship warranty, guaranteeing the quality of the installation. This warranty covers any defects or issues arising from improper installation but does not cover damage from external forces or lack of maintenance.
Peace of Mind: This warranty provides homeowners with peace of mind, knowing that any problems related to the installation will be addressed without additional costs for a significant period.
Project Highlight: Custom Solutions and Quality Assurance
A key highlight of this project is the custom approach taken to address the specific needs of the residence, including the selection of high-quality materials and precise installation techniques. The use of a 2-ply flat roof system is particularly noteworthy for its durability, waterproofing capabilities, and suitability for residential buildings with low-slope or flat roofs. The comprehensive 15-year workmanship warranty further underscores the commitment to quality and customer satisfaction, ensuring that the new roof will provide reliable protection and performance for many years.
This detailed approach to a 4-layer residential roof tear-off and installation project ensures a durable, efficient, and high-quality roofing system that enhances the home's value and protection against the elements.
