Semi-annual and annual maintenance programs structured around manufacturer warranty requirements and Wasatch Front seasonal risk windows - documented drain-clearing before freeze season, post-melt membrane assessment in spring, and the written inspection record that keeps your NDL warranty active when you need it.

The most common reason manufacturer warranty claims get denied on Wasatch Front commercial buildings is not installation defect - it is missing maintenance documentation. Every 20-year NDL warranty from every major manufacturer requires documented periodic inspection by a credentialed contractor. The specific interval varies: Carlisle requires semi-annual inspection on NDL policies, GAF requires annual. Miss that documentation window, and the manufacturer has a contractual basis to deny a leak claim - even if the leak originated at a seam they warranted and even if the leak happened during a Utah winter event the building had no reasonable way to prevent.

Our maintenance contracts are structured around each manufacturer's specific inspection protocol and documentation requirements. We are not conducting a general roof walk - we are following the manufacturer's checklist, photographing every item they require, and retaining documentation in the format that survives a warranty claim review. The inspection schedule is also aligned with Wasatch Front seasonal risk windows: a fall inspection before the first freeze clears drains and documents membrane condition going into winter, and a spring inspection after the freeze-thaw season closes documents any failures driven by the winter's cycling.

We maintain contracts for building owners and property managers who either inherited a building with an existing manufacturer warranty they need to keep active, or who installed a new roof and want to protect the warranty investment. We also run maintenance contracts on buildings with no active warranty - because a documented inspection record still supports capital planning and property transaction due diligence regardless of warranty status.

What We Inspect and Document

Field membrane: We walk the full membrane surface systematically - not a spot-check, not a drone survey without a boots-on-roof follow-up. We note and photograph every blister, puncture, seam edge crack, and surface brittleness location. Membrane areas showing surface cracking or chalking consistent with elevation UV degradation get flagged for action before the next freeze cycle drives water into those failures.

Perimeter flashings: Parapet base flashings, counter-flashings, and edge metal are the highest-failure-rate locations on any Salt Lake City commercial roof. Freeze-thaw cycling works relentlessly at every flashing termination - the expansion and contraction at metal-to-membrane interfaces opens gaps that would not exist in a lower-cycling climate. We inspect every linear foot of perimeter flashing, note every separation or open lap, and photograph against the roof plan so you have a location-keyed record rather than a general statement.

Drains and overflow scuppers: Every roof drain body, ring, and strainer is inspected for debris blockage and verified operational. Overflow scupper elevation is checked against the roof field to confirm the secondary drainage path functions as designed. Ice bridging potential is assessed at each drain location. Pre-freeze drain clearance is documented with photographs - this is the single highest-value inspection deliverable for a Wasatch Front building and the one most directly correlated with avoiding snowmelt emergency response.
