Novi Subdivisions — Three Replacement Waves, Each With Its Own Roofing Profile

Novi's subdivisions were built in distinct eras, and each era has its own roofing lifecycle stage and set of considerations. Here's how the major Novi subdivisions break down from a replacement standpoint.

What We Find on Novi Homes — Era-Specific, Complexity-Driven

Novi's roofing findings are shaped by two variables that don't appear together in many other markets: the large, complex colonial rooflines that multiply every failure point, and the distinct construction era of each subdivision that determines which code deficiencies were never installed in the first place.

• Multi-ridge colonial complexity — more failure points than square footage suggests Novi's colonials have front gable projections, dormers, side wings, and garage additions that each create valley intersections, step-flashing runs, and ridge transitions. On a 3,500 sq ft Bradford colonial, the flashing scope alone equals what you'd see on a 5,000 sq ft simple gable home. Every valley, every dormer, every wall junction is a potential failure point if not installed and sealed correctly.
• Ice & water shield — inconsistently applied on 1980s–early 1990s builds Required per IRC R905.2.7. Homes built before the mid-1990s commonly lack it at the eaves and valleys. On Novi's larger colonials where valley intersections are numerous, ice dam water that penetrates a failed valley without membrane protection travels far before it becomes a visible interior leak. We install membrane at all eaves, valleys, and penetrations on every replacement regardless of the home's age.
• Drip edge — missing on pre-1990 builds, sometimes misinstalled on 1990s homes Required per IRC R905.2.8. Standard on Novi's older subdivisions (Village Oaks, Carriage Hill era) and occasionally incorrectly installed on 1990s homes. On Novi's larger colonials with substantial overhang profiles, proper drip edge is critical for preventing fascia rot on homes where landscaping and mature trees keep the shaded eaves persistently damp.
• Step flashing at dormers and garage walls — the most common failure source on 1990s colonials Dormers and the wall-to-roof junctions on Novi's garage wing additions are where leaks originate on 1990s-era colonials that are now entering first replacement. Original step flashing on these homes is commonly corroded, improperly counter-flashed, or has lost sealant adhesion after 25–30 freeze-thaw cycles. We replace all step flashing as part of a complete replacement — never just slide new shingles over old flashing.
• Ventilation on 1980s–1990s colonials — box vents on large attic volumes Novi's larger colonials from the 1980s and 1990s have substantial attic volumes that box vents and gable louvers simply cannot ventilate adequately. Converting to a continuous ridge-and-soffit system on a 3,000+ sq ft colonial makes a meaningful difference in attic temperature and moisture control — and on a $450,000+ Novi home, the upgrade cost is well justified by the roof life extension it provides.
• Sealant strip degradation on 2000s-era homes — earlier than expected Island Lake, Autumn Park, and similar 2000s developments are seeing sealant strip failure on south and west exposures earlier than their age would suggest — Michigan's UV intensity and temperature cycling is hard on adhesive sealants. On rooflines with significant south-facing pitch, lifted tabs and sealant failure are what cause wind uplift damage in storm events. We assess adhesion on every home during inspection, not just the older ones.
