Roofers in Troy, MIRoof replacement & repair estimates in Troy, Michigan

Troy publishes its own re-roofing handout for homeowners, and under it a Troy roof can carry no more than two layers of shingles. Roofers Royal Oak takes roofing requests from Troy, which shares a boundary with Royal Oak, and passes each one to a roofing contractor who covers the city's ZIP codes. Say whether you need a repair or a full replacement when you ask.

Most of the city was built from the 1960s through the 1990s, so many Troy roofs sit on houses that are decades old. The sections below set out what the city asks for before and during a re-roof.

Troy homes and their roofs

The Census Bureau's 2020–2024 survey puts the median Troy home's build year at 1977. By our arithmetic from the same survey, 11,311 of the city's 34,883 homes (32.4%) were built in the 1970s and another 9,845 (28.2%) between 1980 and 1999, so roughly three in five went up in those three decades.

The city's Master Plan 2040 says Troy's first plan was "originally adopted in 1965" and was "crafted to control the rapid growth that occurred from the 1960s through the 1990s." It talks about the city's "overwhelmingly single family nature" and notes that "Large three and four bedroom homes appeal to families". By our arithmetic from the Census figures, 70.9% of Troy homes are detached houses, and owners live in 73.3% of the occupied ones.

A large two-story house with dormers, valleys and an attached garage has more roof, and more joints to flash, than a plain gable. On a 1970s or 1980s house, ask first how many layers are on it now: Troy's layer limit decides whether a new layer can go on at all.

What Troy's re-roofing handout says

The Building Department's homeowner guide, "Residential Re-roofing", says the permit lets the department inspect the work for hazards and unsafe construction. The online copy is a 2022 scan with a checklist marked "Updated 2/16/16", so confirm anything important with the city. The main points:

• Layers: asked how many layers of roofing are allowed, the handout answers "A maximum of two layers."
• Doing it yourself: to "May I, as the owner, do the re-roof myself?" the handout's answer is "Yes."
• The application: it needs a written scope of work and "A manufacturer's specification sheet for the shingles".
• Nailing and edges: "Fasten with 4 nails per strip shingle and 6 nails in high wind areas." The handout also says "Drip edge is required around entire perimeter of roof."
• Old vents and roof jacks: "These must be replaced if they are in poor condition, badly rusted or otherwise deteriorated."
• Heavier roofing: "An engineered analysis of the roof structure is required if the roofing material type exceeds 7.5 pounds per square foot." That matters if you're weighing tile or another heavy material, and "A mid roof inspection may be required."

Permits and inspections on a Troy re-roof

On inspections, the handout says "the permit holder must call for an open roof inspection and a final roof inspection. Please consult the Building Department when you receive your permit." Its checklist then sets out two sequences, depending on the job:

• New shingles over the old roof (a roof cover): a pre-inspection to check the condition and number of the existing layers, then a final inspection.
• A tear-off: an open deck inspection with the old roofing removed, an ice/shield underlayment inspection, then a final inspection.

Hiring a roofing company in Troy: the permit and its cost

Troy's Permit Requirements page says roofing permits, along with window and siding permits, can be applied for online through BSA Online. The handout's hiring tips are to use only contractors who hold a state license and to "Have the contractor apply for the required permits." You can check any roofer on the State of Michigan license lookup.

The fiscal 2026–27 fee schedule has no re-roof line. Building permits are charged on the value of the work plus plan review, and the schedule doesn't say how that applies to a re-roof, so call the building department to confirm the fee. It does charge $90 for each additional inspection after the first three. Ask the roofer who books each inspection and how the open deck is kept dry while it waits.

Work hours, dumpsters and homeowners associations

Troy's city code (Chapter 88, section 9.5(h), "Construction Noises") bars building work "other than between the hours of 7:00 a.m. and 8:00 p.m. on Mondays through Saturdays, unless a permit be first obtained from the Building Department for building work or from the Engineering Department for street work." The city's Code Enforcement pages list all of Sunday among the prohibited times, and a violation is a civil infraction with a fine of up to $500.

Troy doesn't publish a dumpster rule of its own. Its Engineering Department says a right-of-way permit is needed "Anytime work is being performed in the right-of-way; whether it's maintenance work or new construction", so if the roll-off can't go on your driveway, ask Engineering before it lands on the street or sidewalk.

The Master Plan notes that "Most residential streets in Troy are classified as local roads, and are often located in subdivisions." Where a subdivision has an association, the re-roofing handout says: "If your neighborhood has a Homeowners Association, we advise you contact them prior to making any changes to your roof covering materials."

Hail, wind and trees in Troy

NOAA's Storm Events Database, compiled from National Weather Service Detroit/Pontiac reports, records hail an inch across in Troy twice in recent years: on April 5, 2023, during isolated severe storms across Oakland and Macomb counties, and on May 19, 2024, when a trained spotter reported what the record calls "penny to quarter size hail". Hail can bruise shingles without leaving a hole, so after a hailstorm it's worth checking the gutters for loose granules.

The February 22, 2023 ice storm reached the whole county. The database says areas along and south of I-69 saw "widespread ice accumulations of a quarter to half inch", and it puts property damage in the Oakland County zone at $11 million.

Troy's Code Enforcement Division says trees and brush "originating between sidewalks and streets are maintained by the City." The Facilities & Grounds page takes requests to remove a right-of-way tree and says "Troy has been recognized as TREE CITY USA for more than 25 years."

Roof repair and roof replacement in Troy

• Roof replacement: tear-off to the decking, new underlayment, ice and water shield, flashing, ventilation and shingles.
• Roof repair: missing or storm-damaged shingles, flashing at chimneys and walls, and cracked pipe boots.
• Roof leak repair: tracing where the water gets in, which is rarely right above the stain.
• Garage roofs: detached garage roofs, and what a garage re-roof involves.
• Ice dams: why they form at the eaves and what fixes them for good.

What a roof costs in Troy

Every roof is priced after a roofer has looked at it, because size, pitch, layers to remove and decking repairs make the difference. We publish sourced Royal Oak price ranges, with what makes one roof cost more than another, in the roof replacement cost guide and the roof repair cost guide. They're published guides, not quotes for a Troy roof.
