The Roofing Company Commerce MI Lake Homeowners Call

Commerce Township is lakes country, and that produces a housing stock unlike anywhere else in Oakland County. A great many homes here started life as summer cottages, got winterized somewhere along the way, and have been added onto once or twice since. Homeowners looking for a roofing company Commerce MI can send out are frequently dealing with a roof that is not one roof at all but three or four, built decades apart, meeting each other at junctions nobody designed on purpose.

Then there is the water. A lakefront elevation takes wind and moisture that the road side of the same house never sees, and roofs here routinely fail on one side years before the other.

The Converted Cottage Problem

Several framing generations on one structure

A typical Commerce lake house might be a 1940s cottage core, a 1960s winterization that enclosed the porch, a 1980s bedroom addition off the back, and a 2000s expansion. Each was built to the standards and by the crews of its own decade.

That means different rafter sizes, different deck materials, and different pitches all on one house. Plank sheathing under the original section, plywood under the eighties addition, OSB under the newest. Fasteners behave differently in each, and a crew that assumes uniformity will get it wrong somewhere.

Junctions nobody designed

Where an addition meets an original roof, someone made a decision. Sometimes a good one. Often the addition roof simply butts into the existing plane at whatever angle the framing produced, creating a transition that needs deliberate flashing and frequently did not get it.

These awkward junctions are where the majority of Commerce leaks originate. They are also why interior staining here so often appears somewhere unrelated to the actual entry point, because water follows framing across the seam between two eras of construction before it drops.

Original framing that was never meant for this

A summer cottage roof was built to shed rain in July. It was not designed for decades of Michigan snow load, and it was certainly not designed to carry the insulation that got added when the place was winterized.

We occasionally find undersized or sagging original rafters during tear-off. That is a structural conversation rather than a roofing one, and it should be identified honestly rather than shingled over.

Low-slope additions and sunrooms

Enclosed porches, sunrooms, and rear additions on lake properties are frequently low-slope, built to preserve a view or keep a ceiling height. Asphalt shingles do not work below roughly a 2:12 pitch, and where a previous contractor ran shingles across one of these, the decking underneath is usually soft.

What Lakefront Exposure Does

Persistent wind off open water

Wind coming across a lake has nothing to slow it. Unlike a storm event that passes, this is a constant condition on the water-facing elevation, working at the same shingle edges day after day.

The result is asymmetric aging. We regularly inspect Commerce roofs where the lake side has broken seal across most of the field while the road side is still sound. A quote that treats the whole roof as one condition has not looked at both sides.

Moisture and winter ice at the waterside

Humidity off the water keeps the lake-facing slope damp longer after every rain and every thaw. In winter that translates into more ice at the eave on that elevation, and more freeze-thaw cycling working at the shingle edges and flashing.

Sun on the water side

Lakefront lots are cleared toward the water for the view, which means the water-facing slope typically gets far more direct sun than the wooded road side. Wind, moisture, and UV all concentrating on one elevation is why that side ages so much faster.

Boathouses, Sheds, and Detached Structures

Waterfront and large wooded lots come with outbuildings, and on lake property they matter more than usual. A boathouse or storage structure near the water sits in the most exposed position on the parcel and is typically the least maintained thing on it.

These are small, simple roofs. They are also the ones where a leak goes unnoticed for years because nobody is inside during the months when it rains hardest. We inspect and quote them with the house, since one mobilization on a long lakefront driveway is worth considerably more here than on a compact suburban lot.

Permitting Through the Township

Commerce Township handles building permits at the township level rather than through a city building department, and roof replacement requires one with inspection at completion. We pull it as part of every replacement contract.

One thing specific to lake properties: if your home has additions that were never permitted, which is not unusual on parcels with a long history of incremental building, that can surface during the permit process. It is far better to find out during a roofing project than during a sale. We would rather raise it early than have you discover it at closing.

Seasonal and Second Homes

Some Commerce properties are still used seasonally, and a few owners are not local. That changes a few practical things.

A house that sits empty from November to April can develop a leak that runs unattended for months. By the time anyone opens it up, water has been working on framing and insulation all winter. If your property is seasonal, an inspection before you close it up is worth considerably more than one in the spring.

For owners who are not local, we document photographically and can handle access coordination. Decisions get made from photos and a written scope rather than from a driveway conversation.

How We Inspect a Commerce Roof

Section by section rather than as a whole, because on a house built in four stages the sections genuinely differ.

Exterior: each roof plane assessed separately with the lake-facing elevation evaluated on its own terms, every addition junction examined specifically, low-slope sections assessed as their own systems, and detached structures included.

Interior: attic and crawl spaces where accessible, which on a converted cottage may mean several disconnected spaces rather than one attic. We look for staining, decking condition by era, framing adequacy in the original section, and whether ventilation exists in each area independently. Winterized cottages frequently have one section that breathes and another that does not.

Repair or Replace on a Layered Roof

Sectional replacement is genuinely legitimate here in a way it is not on a simple house. If the lake-facing slope is finished and the road side has ten years left, replacing one side is a reasonable decision rather than a compromise. Same with an addition roof that is failing while the original section is sound.

The honest caveat is appearance. New shingles against weathered ones will not match, and on a house where both sections are visible from the same angle, you should see what that will look like before committing.

Full replacement makes more sense when multiple sections are failing at once, when the junction detail between eras is bad enough that piecemeal work means returning, or when you are already carrying two layers anywhere. It is also the moment to correct low-slope sections that never should have had shingles.

Materials for Lakefront Roofs

Wind exposure drives the main roof specification. Architectural shingles are the floor, installed to the manufacturer's high-wind nailing pattern rather than the minimum, with purpose-made starter strip at eaves and rakes and drip edge throughout. On the water-facing elevation especially, perimeter detail is doing the real work.

Low-slope additions and sunrooms need a membrane system, not shingles. That is a separate material and it should appear as a separate line on your quote.

We install as a CertainTeed Master Shingle Applicator, which determines the manufacturer warranty coverage available on your roof.

Documenting Damage on a Multi-Section Roof

Storm claims get complicated when a house has sections of very different ages. An adjuster looking at a roof with a 1985 addition and a 2010 expansion will reasonably ask which damage is storm and which is age, and on a layered property that question is harder to answer than usual.

We photograph by section, document each area's condition separately, and produce an itemized scope in the format carriers expect. Separating pre-existing wear from storm damage protects you rather than working against you.

Michigan contractor licensing is administered by the Michigan Department of Licensing and Regulatory Affairs, and it is worth verifying for anyone you let on the property.

Access on Wooded and Waterfront Lots

Commerce lots are large, often wooded, and frequently sloped toward the water. Long private drives, limited turnaround for a delivery truck, mature trees restricting boom access, and septic fields you do not want a loaded truck parking on.

We walk the property before quoting and agree on delivery, staging, and dumpster placement rather than improvising on the morning of. A crew that arrives expecting a suburban driveway will make choices you did not authorize.

Commerce Roofing Service Area

We work throughout Commerce Township, including the lakefront neighborhoods, the subdivisions off Commerce and Union Lake Roads, and the larger wooded parcels toward the western side of the township. We also serve the surrounding Oakland County lakes-area communities.

Reading Your Property's Build History

Before quoting a Commerce lake home we try to establish roughly what happened and when, because it predicts what tear-off will find. Homeowners can usually piece most of it together themselves.

Look at ceiling heights. A step down or up between rooms almost always marks a seam between building eras. Where the ceiling changes, the roof above it probably does too.

Look at the foundation from outside. Block, poured concrete, and slab sections tell you the sequence of additions clearly, and the roof follows the same order.

Look for interior walls that were once exterior. Thicker walls, an odd window opening into another room, or siding discovered during a remodel all mark the original footprint.

Count the attic accesses. More than one usually means more than one roof cavity, which is the ventilation question in miniature.

None of this is required of you. It simply makes the first conversation faster and the estimate more accurate.

What Fails First on a Layered Lake House

The order is fairly consistent across properties here, and knowing it helps you prioritize.

Section seams go first, nearly always. The junction between original and addition is the weakest detail on the house and the one most likely to have been improvised.

Low-slope sections follow, particularly where shingles were installed on a pitch that could never support them.

The lake-facing field shows seal failure next, from persistent wind and concentrated sun and moisture.

Outbuilding roofs are usually failing throughout this whole sequence and simply are not noticed.

The road-side field is generally last, often with years of life remaining when everything else is finished. That asymmetry is precisely why sectional replacement is a legitimate strategy here rather than a shortcut.

Maintenance That Matters on Lake Property

A few habits pay for themselves here more than in a typical suburb.

Walk the lake-facing side after windy stretches and look for shingle fragments or granules on the ground. That elevation takes the load and gives the earliest signal.

Check any sunroom or enclosed-porch ceiling for staining a couple of times a year. Low-slope sections fail quietly and the decking softens before anyone notices.

Clear gutters more often than you think you need to on a wooded lot, and confirm that downspouts discharge away from the house rather than toward the water on a sloped lot.

If the property is seasonal, inspect before you close it up rather than after you reopen. A leak that begins in November has all winter to work.

Why Commerce Homeowners Work With Us

We have been working Southeast Michigan for more than 25 years, and layered lake properties are familiar rather than unusual for us.

Verifiable Michigan licensing, full liability and workers' compensation coverage, employed crews rather than subcontractors, township permits pulled on every job, and CertainTeed Master Shingle Applicator certification that determines your available warranty coverage.

What matters most on these houses specifically: we quote each section on its own terms, we specify membrane where the pitch demands it instead of running shingles across, we assess every roof cavity for ventilation rather than assuming one attic, and if tear-off reveals framing that was never sized for the load, we stop and tell you instead of covering it.

Frequently Asked Questions: Roofing Company Commerce MI

Can I replace just the lake side of my roof?

Often yes, and on a house where that side has aged much faster it can be the sensible call. The trade-off is appearance, since new shingles will not match weathered ones. We will show you what to expect before you decide.

My house was a cottage originally. Does that matter?

Considerably. Different framing, different decking, and junctions between eras that need deliberate flashing. It is the defining characteristic of roofing in this township.

My sunroom ceiling stains every year. Why?

Almost certainly shingles installed on a slope too low for them. That section needs a membrane system rather than another layer of shingles.

What if my addition was never permitted?

It can surface during the roofing permit. Better to address it now than during a sale. We will tell you what we find rather than working around it quietly.

Do you handle boathouses and sheds?

Yes, and we prefer to quote them with the house. One trip up a long lakefront drive is worth more than two.

Should I inspect before closing up a seasonal property?

Yes. A leak that starts in November runs unattended until spring, and that is how a minor repair becomes framing work.
