CertainTeed Landmark Installation Guide for Roofing Contractors
CertainTeed Landmark asphalt shingles represent a mid-range architectural product that requires specific installation protocols and documentation standards for insurance claim processing. Understanding the nuances of this product line will streamline your project workflow and reduce claim disputes with insurers.
CertainTeed Landmark Specific Installation Requirements
CertainTeed Landmark shingles are premium three-tab architectural products featuring dimensional shadow lines and enhanced weather resistance. Installation must comply with CertainTeed's published specifications, which mandate proper nail placement—specifically four nails per shingle positioned within the factory-designated nail strip, approximately 5/8 inches above the cutout. Improper nailing is a common adjuster concern and primary reason for claim denials. Ensure your crews understand that nails must penetrate the underlying wood deck by 3/4 inches minimum. CertainTeed Landmark requires H-strip self-sealing adhesive activation in temperatures above 40°F; document ambient temperature at installation time in your work logs.
Underlayment installation is non-negotiable. CertainTeed recommends synthetic underlayment for Landmark installations due to the product's performance specifications. Standard 15-pound felt is increasingly questioned by adjusters, so specify synthetic options in your estimates to preempt supplemental requests.
Xactimate Line Items and Codes
When entering CertainTeed Landmark into Xactimate, use the following primary codes: ROOF SHINGLES - ASPHALT - ARCHITECTURAL for the base shingle coverage. Code the specific product as "CertainTeed Landmark" in the description field with color designation. For roof removal, use ROOF TEAR OFF - ASPHALT SHINGLES. Include separate line items for ice and water shield (ROOF UNDERLAYMENT - ICE/WATER SHIELD), synthetic underlayment (ROOF UNDERLAYMENT - SYNTHETIC), and drip edge materials (ROOF DRIP EDGE). Many contractors miss the drip edge line item, which creates supplement opportunities. When applicable, code ridge cap shingles separately using ROOF RIDGE CAP - ASPHALT SHINGLES. Labor is typically coded as ROOF SHINGLES - INSTALLATION - ASPHALT ARCHITECTURAL.
Common Adjuster Pushback and Counter-Strategies
Adjusters frequently challenge CertainTeed Landmark claims by questioning whether damage warrants full replacement versus spot repairs. Counter this by documenting that architectural shingles like Landmark cannot be spot-repaired without visible color/texture mismatches due to UV fading in surrounding shingles. Provide manufacturer documentation stating that repair versus replacement decisions should consider the shingle's remaining lifespan. Some adjusters attempt to depreciate Landmark shingles as standard three-tab products. Respond by submitting CertainTeed's product specifications highlighting the architectural grade classification, which commands premium pricing justified by enhanced durability and aesthetic value. If adjusters propose generic asphalt alternatives, present a cost analysis showing CertainTeed Landmark's competitive pricing within the architectural segment.
Damage Documentation Protocol
Photograph damaged sections from ground level and roof-level angles, clearly showing the distinctive Landmark shadow lines and damage pattern. Document the shingle's age if determinable through CertainTeed warranty records. Include close-up images of nail penetration quality and any installation defects. Create a detailed damage report specifying the affected roof section square footage and the percentage of shingles requiring replacement.
Supplement Tracking for CertainTeed Landmark
Maintain a dedicated supplement log tracking initial estimate amounts versus supplemental requests. Flag missing line items such as drip edge, ice and water shield upgrades, and ridge cap materials. Monitor for adjuster-requested downgrades to standard asphalt products and document your counter-proposals with supporting evidence. Track approval timelines for supplements—CertainTeed Landmark claims typically require 7-10 business days for supplement processing. Create a master spreadsheet recording all CertainTeed Landmark projects with policy information, initial estimate codes, approved supplements, and final project costs for trend analysis.
