Roofing Contractor Notes on iPhone: Decking Assessment, Flashing Details & Warranty Notes
How roofing contractors use Nemos to track decking condition notes, flashing sequence decisions, material lot numbers, and ventilation calculations across residential and commercial roofing.
Note-Taking for Roofing Contractors
Roofing is high-stakes work where material selection, installation sequence, and flashing detail determine whether a roof lasts 15 years or 30. Each job involves decking assessment, underlayment selection, flashing approach at every penetration and transition, ventilation calculation, and material documentation for warranty purposes.
Nemos keeps your technical reference and job-specific records organized.
What Roofing Contractors Track
Decking and substrate: - Decking condition assessment notes (soft spots, rot extent, sheathing type) - Decking replacement quantity notes before ordering - Existing underlayment and ice and water barrier observations - Ventilation assessment notes (existing intake and exhaust, NFA calculation)
Materials and specifications: - Shingle manufacturer, product line, color, and lot number per job - Underlayment type notes by application (synthetic felt vs. ice and water barrier zones) - Flashing material notes (pre-formed vs. step flashing, lead vs. aluminum vs. copper at specific applications) - Fastener type and pattern notes by product and code requirement
Flashing and waterproofing: - Valley treatment notes (open metal, closed, woven) - Pipe boot and penetration flashing approach notes - Chimney and skylight flashing sequence notes - Wall-to-roof transition and step flashing sequence
Warranty and documentation: - Manufacturer warranty registration requirements per product - Installation requirement notes that affect warranty (ventilation ratio, underlayment type) - Photo documentation checklist notes before covering substrate
Weather and logistics: - Temperature range notes for specific adhesive products and shingle installation - Rain window tracking for multi-day jobs - Dumpster placement and debris management notes
Documenting for Warranty Protection
Many roofing manufacturer warranties require specific installation details to remain valid — proper ventilation ratios, specific underlayment, fastener pattern. Notes on what was installed and how protect both the customer's warranty and your installation.
FAQ
What decking notes prevent mid-job surprises? Soft spot and rot extent notes from the initial tearoff. Material orders based on accurate assessment prevent emergency runs to the supply house mid-job.
Should I note lot numbers for shingles? Yes — for warranty claims and color matching if additional materials are needed. Lot numbers affect color; mixing lots causes visible bands.
How do I handle flashing detail notes? A checklist note per flashing type (valley, chimney, pipe, skylight, wall) with the approach used. These are the details that produce callbacks when skipped or done incorrectly.
What ventilation notes prevent issues? NFA calculation for the specific roof area, intake and exhaust balance, and what was installed. Improper ventilation voids manufacturer warranties and causes premature shingle failure.
Is Nemos useful for estimating? Square footage to material conversion notes, waste factor observations by roof pitch and complexity, and labor time per square by difficulty — all calibrate your estimating accuracy.
How do I organize by job type? Tags: `#shingle`, `#metal`, `#flat`, `#commercial`, `#residential`, `#repair`. Cross-reference with material brand and flashing approach.
