Get the facts on paper
Note where it is, when it started, any weather connection, how it's progressed, and past repairs -- that beats a vague description every time.
Read the Local Context
West Michigan sits in Lake Michigan's lake-effect snowbelt, and Grand Rapids' winter precipitation load -- more than three feet of snow fell in February 2013 alone, ahead of that April's major flood -- puts real, recurring weight on rooflines across the city's mix of century-old Heritage Hill homes and later twentieth-century construction.
Think about what disappears at closeout
Deck soundness under decades of lake-effect snow load, ice-dam history at the eaves, ventilation balance, and valley and penetration flashing -- not the shingle brand -- point toward repair or full replacement. The written scope should explain the preparation and verification that will no longer be visible at completion.
Weigh the whole scope
A complete proposal covers protection, access, materials, permits, testing, cleanup, restoration, exclusions, and change orders.
What official local sources add
The stormwater provisions touch roofing indirectly but genuinely: a roof is the surface generating the runoff that Low Impact Development and the 2021 MS4 retention requirement are aimed at, so a replacement that changes roof area or relocates drainage changes what the site has to retain. Chapter 32 reaches roofing only through the substantial-work threshold inside a Special Flood Hazard Area. The dominant physical factor is snow: West Michigan loading and ice damming at the eaves make ventilation and ice-barrier detail matter more than shingle brand.
