Roof replacement
Roof Replacement in Whitmore Lake, Michigan
Whitmore Lake sits on a county line, and so does every roofing job here. The lake itself — 667 acres, all-sports, straddling Green Oak Township in Livingston County and Northfield Township in Washtenaw — is ringed by homes built anywhere from 1870 to 2015, with the heaviest concentration from the 1920s through the 1950s. Behind the shoreline, Green Oak's 1990s and 2000s subdivisions and Northfield's 1980s and 90s stock are on original roofs that are done. We replace all of it with a full tear-off, a complete Owens Corning system and a registered warranty, and we know which of the two township offices your address answers to.
Whitmore Lake is not a city — it is a lake and a community split between Green Oak Township in Livingston County and Northfield Township in Washtenaw County, each with its own building department.
Which building department handles my roof in Whitmore Lake?
It depends on which side of the county line your house sits on, and the two townships run their own departments — neither one uses a county office. If you are in Green Oak Township, the Green Oak Building Department at 10001 Silver Lake Road (a Brighton mailing address) issues the permit, and its rule is that a tear-off and re-shingle needs one while a layover over existing shingles does not. If you are in Northfield Township, the Northfield Building Department at 8350 Main Street in Whitmore Lake issues it, and residential roofing is on its permit list. Both offices run Monday through Thursday. We confirm which township your parcel is in on the estimate visit — the lake road is not a reliable guide — and we pull the permit either way, because every roof we replace is a full tear-off.

A lake with a hundred years of roofs on it
Whitmore Lake's shoreline housing dates from 1870 to 2015, and the bulk of it was built between the 1920s and the 1950s — colonials, Cape Cods, ranches, bungalows and split-levels on lots reached by a mix of paved and gravel roads, with no condominiums and no estates on the water. The community itself was settled in 1825, the post office took the name Whitmore Lake in 1854, and the Whitmore Lake census area now holds about 7,600 people; one home in eleven there predates 1940 and two in five date to the 1980s and 90s.
A cottage roofed since the 1930s has been re-covered many times, and Michigan's Residential Code prohibits a re-cover where two or more layers of any covering already exist or where the roof is water-soaked or deteriorated. On these houses that limit was hit decades ago. Full removal is the law, disposal roughly doubles, and — for the first time in a long time — someone sees the deck.
- Layer count confirmed before the estimate — two or more existing layers means full removal by law
- Spaced plank sheathing sheeted over; soft boards replaced and photographed
- Membrane on sections under 2:12; double underlayment from 2:12 to 4:12
- Crickets framed into dead valleys where additions meet
- Ice barrier to 24 inches inside the wall line, and 36 inches up the slope on any pitch of 8:12 or steeper
- Metal drip edge at every eave and rake — most cottages have never had it
- Rake starter and high-wind fastening on the lake-facing elevation
- Owens Corning Duration or Duration Designer with matching hip-and-ridge
Rebuilding a cottage roof rather than re-covering it
A lake house that grew a room at a time carries several roof planes at different pitches from different decades, meeting at valleys nobody designed. When all of it comes down to the deck, those can be reconciled. Sections under 2:12 — the enclosed porch, the shed dormer — cannot legally take asphalt shingles and get a membrane. Sections between 2:12 and 4:12 get double underlayment under the code. Dead valleys where two additions meet get a cricket framed in. Spaced plank decking gets sheeted over with new panels. Rafters sized for a seasonal building and carrying three layers of asphalt through Michigan winters get looked at while the roof is open. And on the water side, where a westerly across 667 acres reaches the roof first, we run starter at the rakes and fasten to the manufacturer's high-wind pattern.
Green Oak's own FAQ says the state code allows a maximum of three layers. The code we build to prohibits a re-cover over two or more, and we tear off regardless — the point of the rule is that nobody should be shingling over a deck they have not seen.
Behind the shoreline: Green Oak's 1990s and Northfield's 1980s
Away from the water the story is a first tear-off. Green Oak Township's median home was built in 1991; a fifth of its housing dates to the 1990s and another fifth to the 2000s, and 91.5 percent of it is owner-occupied — one of the highest rates in Livingston County. Northfield Township's median is 1985, with its largest cohorts in the 1990s at 24 percent and the 1980s at 16 percent, and one home in ten predating 1940 in the old village blocks around Main Street.
Those 1980s–2000s roofs were built to the code and the builder practice of their day: 7/16-inch OSB on trusses two feet apart, a gable vent at each end and a few box vents, insulation pushed against the sheathing at the eave, a single 36-inch course of ice barrier, and no drip edge at the rakes, which Michigan did not require until the 2012 cycle. At 25 to 40 years old they are at or past the end of a first roof, and the replacement is where all of that gets corrected — drip edge at every edge, two courses of ice barrier to reach 24 inches inside the wall line, gable vents sealed and a ridge vent cut over real soffit intake with baffles in every rafter bay, and every OSB panel checked for edge swelling once the old roof is off.
Hidden Lake and the gated side of Green Oak
Hidden Lake, off Silver Lake Road with a South Lyon mailing address and Brighton schools, is a 350-acre gated development around a 110-acre private all-sports lake, planned at 425 units and built through the 2000s and 2010s. Its earliest homes are now at the age where a first roof gives out, and its architectural standards govern shingle color and profile — Green Oak Township does not enforce association rules, so the association does. We read them before color is chosen and prepare the submission with the product sheet and color chip attached. Centennial Farms, the 55-plus condominium community, and Green Oak Crossing's ranch condominiums are association roofs, where the association rather than the resident contracts the work.
Two townships, two sets of rules
The county line runs through the lake, and it changes the workday as well as the permit.
Northfield Township's noise ordinance prohibits the construction, excavation, demolition, alteration or repair of any building outside 7:00 a.m. to 8:00 p.m. on any day, except by permit from the township supervisor in urgent cases. Green Oak Township's rule restricts power equipment used in construction between 10:00 p.m. and 7:00 a.m. on weekdays and before 8:00 a.m. on weekends, with a 60-decibel daytime limit at the property line in residential districts. So a Whitmore Lake replacement runs seven to six on either side of the line, Saturdays are possible with an eight o'clock start, and we keep compressors off at dusk regardless of which township is listening.
The Green Oak Building Department at 10001 Silver Lake Road is open Monday through Thursday, 7:30 to 4:00, with inspections typically between 9 and 3. Northfield's department at 8350 Main Street runs Monday through Thursday, 7:30 to 5:30, closed Fridays, with inspections on Monday and Wednesday mornings and all day Thursday on a day's notice. Neither township publishes a dumpster or right-of-way rule; road rights-of-way here belong to the Livingston or Washtenaw County Road Commission. Our default is your driveway on plywood, and where a lake lot has no driveway to speak of we work from a trailer we can move.
Getting here, and getting down the lake road
Our Howell yard on Sterling Drive is about twenty minutes from Whitmore Lake down US-23, and the drive got easier in June 2026 when MDOT's Flex Route extension from M-36 to I-96 opened its shoulder lanes after three years of construction. The last mile is the harder part: the shoreline roads are a mix of paved and gravel, many are narrow, and some are private. Our default is a boom truck that sets the bundles on the roof from the nearest hard surface, which keeps eight tons off a soft gravel lane and off a septic field; where even that will not reach, we stage and carry. We confirm access with the road association before the first truck rolls.
Whitmore Lake's wind, and the September 2026 storm
Whitmore Lake's storm record is wind, not hail, and it is worth being precise about it because the numbers get inflated. On May 15, 2025, the National Weather Service logged an estimated 56 mph gust at Whitmore Lake that damaged several trees and lifted a silo and barn roof — the same night that put 56 mph on Hartland and Hamburg. Green Oak took a 61 mph gust on August 24, 2023 with trees down across the township, a 55 mph gust in June 2022 and another in June 2024. Whitmore Lake's only hail in the period was 0.88 inch on June 15, 2023 — below the size that damages an architectural shingle.
The September 2–3, 2026 storm added to the list. The overnight line put an estimated 70 mph gust on Howell and a measured 67 mph on the Livingston County Airport, with straight-line winds of 60 to 70 mph across the county for six hours. The following afternoon, at about 3:40, the Weather Service logged tree damage in the neighborhood of Strawberry Lake from a report filed at Whitmore Lake, with more trees and power lines down toward Hudson Mills and at Jackson and Zeeb Roads. No tornado was confirmed in Livingston or Washtenaw County.
What that means for a roof on the water
A westerly across 667 acres of open lake reaches the shoreline roof at full strength, and a cottage roof at the two-layer limit is not sealed to resist it. Wind at 60 mph strips shingles that were already unsealed and breaks the seal on shingles that stay put and look fine from the dock. If your roof was already in its replacement window, have it walked before the fall rains, have the tabs tested by hand, and have the findings photographed with the date recorded.
The new roof is built for it. Owens Corning Duration shingles carry a 130 mph wind resistance limited warranty as standard and a 160 mph enhanced warranty when the full component set is installed with starter shingles at both the eaves and the rakes. We run rake starter on every lake roof and fasten the water-facing elevation to the manufacturer's high-wind pattern rather than the four-nail code minimum. Shingles seal with a heat-activated strip that bonds in about a day in summer and can take up to twelve weeks on a shaded north slope in winter, so a Whitmore Lake roof finished by mid-October seals before the November gales.
The Owens Corning system we register in Whitmore Lake
On Top Roofing is an Owens Corning Platinum Preferred Contractor — the top tier of the Owens Corning contractor network in the company's own words, and the only tier that can offer its best system warranty. Every Whitmore Lake replacement is registered under a Platinum Protection Roofing Limited Warranty: limited lifetime coverage on materials with a 50-year non-prorated period, limited lifetime workmanship non-prorated for the first 25 years, 130 mph wind standard and 160 mph enhanced, and 25-year algae resistance with Owens Corning hip-and-ridge. It transfers once to a buyer within 60 days of a sale — and lake cottages change hands.
It requires the whole system — Duration shingles with SureNail Technology, Owens Corning or approved synthetic underlayment, Owens Corning hip-and-ridge, and Owens Corning self-adhered ice-and-water barrier, starter and VentSure balanced ventilation — plus new flashings and drip edge. We install all of it as standard, which is also what earns the 160 mph enhanced wind coverage.
Colors on the lake
Lake cottages with cedar, stained or earth-tone siding take the Duration Designer line best — Aged Copper, Storm Cloud, Sand Dune, Black Sable. The brick-and-vinyl colonials of Green Oak's 1990s subdivisions and the ranches around Horseshoe and Island Lakes sit well under Driftwood, Estate Gray, Teak or Onyx Black. On exposed lake-facing lots we suggest Duration FLEX, the SBS polymer-modified shingle with a UL 2218 Class 4 impact rating and the same SureNail strip. We bring full-size samples to the dock.
New building on both sides of the line
Both townships are growing. Green Oak issued 136 single-family permits in 2021 and has averaged well over fifty a year since; Dove Lake, 37 homes between Twelve Mile and Dixboro Roads, has preliminary approval, Green Oak Crossing is selling its final ranch condominiums, and Hidden Lake still has sites. Northfield Township approved three large developments in 2025 — Northfield Preserve, 194 homes and condominiums at North Territorial and Whitmore Lake Road; Woodfield Farms and Villas, 166 homes west of Whitmore Lake Road; and The Groves, 328 apartments east of US-23. Green Oak holds about 19,900 people and Northfield about 8,800; Whitmore Lake Public Schools enrolls about 690 students, with the Livingston side of the lake split among the South Lyon and Brighton districts.
We roof new construction in both townships, and a roof built to a Platinum Protection specification from the first day is not at the two-layer limit in 2060.
Whitmore Lake neighborhoods where we replace roofs
US-23 puts our Howell yard at 5896 Sterling Dr about twenty minutes from the lake. We replace roofs on both sides of the county line — the cottage-era shoreline along North Shore and East Shore Drives, the old village blocks around Main Street in Northfield, the 1980s–2000s subdivisions of Green Oak and Northfield, the lakefront at Hidden Lake, Horseshoe Lake and Island Lake, and the new communities going in along Whitmore Lake Road and Silver Lake Road.
