Townhouse Roof Replacement in Minnesota: What HOAs and Owners Should Settle Before Comparing Bids

The short answer: A townhouse roof replacement is usually more complicated than replacing the roof on a detached house, and the shingles are rarely the reason. The decision may run through association documents and a board instead of one owner. The roof may be one continuous surface over several homes, or several buildings that all have to match. There may be a shared budget, one specification that has to hold across every building, and dozens of residents whose driveways, schedules and pets are part of the jobsite. The roofing itself is familiar work. Planning and coordinating it is where these projects succeed or fail.

I’m Jason Berrey. I own Northern Exteriors, and I have been roofing in Minnesota since 2001. This is what I would want a board member, property manager or townhome owner to have sorted out before anyone compares a bid. (Around the Twin Cities you will hear “townhome” at least as often as “townhouse.” Same thing. I use both.)

One caution first: townhome communities are not built or governed alike. Some buildings have one continuous roof with the attic divided unit by unit. Some have a separate roof section over each home. Some have walls that rise above the roofline between units, and some older buildings were built under different rules entirely. Some associations own and control the roofs. Others leave them to each owner. Read everything below as questions to ask about your buildings and your documents, not as assumptions about them.

Three Different Jobs That All Get Called “Roof Replacement”

Most of the trouble on these projects comes from treating the second or third job like the first.

Start Here: Who Controls the Roof?

Before shingle colors and before bids, find out who has the authority and the obligation to replace the roof. The answer is in the association’s governing documents: the declaration, the bylaws, and any maintenance or architectural rules.

Arrangements vary widely. In some communities the association is responsible for roofs and pays through dues and reserves. In others, each owner is responsible for the roof over their own unit while the association controls the approved shingle, the color and the approval process. Some are a hybrid. Two associations across the street from each other can work completely differently.

If the documents are unclear, ask the association’s attorney or management company. A roofer cannot answer it, and neither can the neighbor who is “pretty sure.” It matters to a contractor for a practical reason: a proposal written to the wrong party, or for a scope the board has no authority to approve, costs everyone a month.

If You Own One Attached Unit and the Roof Is Yours

Ask your board or property manager three things before you call roofers:

1. Who is responsible for the roof over my unit?
2. Is there an approved shingle and color?
3. Do I need written approval before work starts?

Then look at where your roof actually stops. On many attached buildings the shingles run straight across the unit line. Replace one unit’s section and you create a vertical seam where new shingles tie into the neighbor’s old ones. That seam is a vulnerable detail for future leaks, and it will show. New shingles do not match weathered ones, even in the “same” color.

Better options, when you can get them:

• Coordinate with the adjoining owners and do the whole building at once
• Stop at a natural break: a ridge, a valley, a step in the roofline, or a wall that rises above the roof
• If a mid-roof tie-in cannot be avoided, have the contractor put in writing how the underlayment, ice barrier and shingles will be lapped at the seam. If any work touches the neighbor’s side, get the neighbor’s and the association’s consent first.

A contractor who quotes your unit without ever bringing up the unit line has not thought the job through.

If the Association Is Replacing Several Buildings

All at once, or phased?

It comes down to roof condition, money and what the documents allow.

One project gives you a consistent appearance, one specification, one warranty start date and one mobilization.

Phasing spreads the cost across budget years, and it makes sense when buildings went up in different phases and the roofs really are different ages. Know the tradeoffs:

• Shingle lines and colors get discontinued or reformulated. Building 1 and Building 9 may not match by year five.
• Pricing moves every season.
• Different contractors in different years means different specs and different warranties. When something leaks, everyone points at someone else.

If you phase, write the specification once and hold it for every phase. Ask for per-building pricing so the board can plan. Rank the buildings by documented condition, not by who complains the loudest. A roof inspection of every building, with photos organized by building, gives the board a ranking it can defend at the annual meeting.

One written scope, priced by every bidder

If three contractors walk the property and each writes their own scope, the board is comparing three different projects. The low number is often just the smallest scope.

The fix is one written scope that every bidder prices. Some management companies supply it. If yours does not, have a contractor help define it after an inspection, then send the identical scope to everyone. Bids drift apart in predictable places: tear-off, decking, ice and water barrier, underlayment, new versus reused flashing, ventilation, gutters, permits and the exact shingle system. Sections B and C of the checklist below cover each one.

A spec that says “architectural shingle or equal” hands the most important choice to the lowest bidder.

Choosing a shingle for a whole community

On one house, the shingle is personal taste. Across an association it is a standard. Choose a product line with a track record and a color likely to stay available. Ask the contractor how materials will be ordered so color stays consistent from building to building. Then record the exact product and color name in the association’s files. Someone will need it for a repair in eight years.

If the community has a hail history, it is reasonable to price an impact-rated option next to a standard architectural shingle. I covered what Class 4 shingles are and where they make sense in a separate article. Whether an insurer gives any premium credit for them is a question for the association’s agent. Do not let a roofer promise it.

What Is Different Under the Shingles on Attached Buildings

Decking: plan for what nobody can see yet

Nobody sees the roof deck until the shingles are off. On one house that is a small unknown. Across eight buildings it is a budget risk, so settle it in writing: a stated decking allowance, a unit price per sheet past it, and photos of every replaced section labeled by building.

Two details matter more on multi-building work. First, ask whether the allowance is per building or pooled across the project. Pooled is often more realistic, because one building may need nothing and the next may need twelve sheets. Second, name a person who can approve overages the same day. A crew standing on an open roof at 10 a.m. cannot wait for next month’s board meeting.

The roof deck near the walls between units

In many attached buildings, the wall separating two homes is a fire-rated wall, and the strip of roof deck on either side of it can be part of that fire-separation design. Depending on the building’s age and design, that strip may be fire-retardant-treated sheathing, it may have gypsum board directly under it, or the wall may rise above the roof instead. Older buildings may be different again.

What matters for a reroof: if decking in that zone needs replacing, it should go back in a way that keeps the original design intact. And before anyone adds roof vents or other penetrations close to that wall, ask the local building official what is allowed. Ask each bidder how they handle it. The answer tells you whether they have worked on attached housing before.

Attic ventilation, one attic at a time

On a detached house there is one attic and one ventilation calculation. In many townhome buildings the attic is divided at the walls between units, so each unit’s attic has to be vented on its own, with its own intake low and its own exhaust high. Not every building is divided this way, which is one more reason somebody has to look.

Units in the same building are rarely identical up there. Widths differ. End units can have a different roof shape than interior units. Dormers, bump-outs and vaulted ceilings interrupt the airflow path. Add a few decades of separate repairs, and one unit may have a ridge vent while its neighbor has box vents, or both on the same attic, which works against itself.

A reroof is the time to look inside the attics, or at least a representative sample, and write the ventilation scope building by building. That takes access inside some units before the bid is final, so plan for it. The intake-and-exhaust basics are in 5 Roof Installation Mistakes Even the Inspector Won’t Catch. Manufacturer warranties commonly require adequate ventilation and may exclude damage attributed to inadequate ventilation.

Flashing at unit lines, stepped roofs and walls

Attached buildings have far more roof-to-wall intersections than a simple house: stepped rooflines where one unit sits higher than the next, sidewalls, dormers, shared valleys, framed chimney chases, and sometimes walls that come up through the roof. Those intersections are where a low bid saves money by reusing old flashing.

Two townhome-specific questions belong in the scope:

• What is new and what is reused? My standard is new step flashing wherever the siding allows it. If a bidder plans to reuse flashing, the proposal should say where and why.
• Who owns the siding? Doing sidewall flashing right often means loosening or replacing siding. On many townhomes the siding belongs to the association too. Decide who handles it, and at what price, before the job starts.

Most flashing is covered up the same day it goes on. On a multi-building project, in-progress photos are the only permanent record the board will ever have.

A Jobsite Where People Live

This part never shows up in a bid, and it is where residents form their opinion of the board.

• Site plan. Where dumpsters or trailers sit, where shingles get delivered, what protects the pavement, and what gets covered at each building. Townhome driveways are short and often shared, and private streets may have to stay open for emergency access.
• Parking. Once a trailer is parked in front of a garage, that car is home for the day. Residents need to hear it the evening before, not at 6:45 a.m.
• Before photos. Driveways, garage doors, siding, AC units and decks at each building, photographed before work starts. It protects the association and the contractor equally.
• Garages and attics. Tear-off shakes dust and grit loose. In garages with open framing, residents should cover or move what they care about.
• Noise. A tear-off is loud and it shakes the building. People work from home, some sleep days, and there are infants and pets. None of it stops a project. All of it goes better with notice.
• Roof-mounted dishes. Decide who removes and resets them, and tell residents that re-aiming may be up to their provider.
• Communication. One contact for the association, one for the contractor. A written notice before each building, and an update whenever weather moves the schedule.

A roofer who communicates poorly with one homeowner will be a catastrophe with forty.

Permits, Sequence and Minnesota Weather

Permits. Permit requirements and procedures vary by municipality. St. Paul, for example, has its own reroof permitting process, and historic properties can follow a different path. The contractor should confirm the permit structure for the property, pull required permits under the contractor’s license, state the permit responsibility in the proposal, and give the association proof that required inspections and permits were closed.

Sequence. Agree on the building order and the rule for moving on. Mine is: finish what you open. A building gets dried in, completed and cleaned up before attention moves to the next, and no more roof comes off in a day than can be made watertight that day. Here is what a good crew does when rain shows up mid-project.

Weather. Minnesota’s roofing season has an end. Asphalt shingles need warmth to seal, and late-season installs can require extra steps under the manufacturer’s instructions. If a board is signing in the fall for a many-building project, ask how many buildings can realistically be finished before the weather closes in, and agree on the stopping point. Half a community torn up in November is a planning failure, not bad luck.

Quality Control Across Buildings: Start With One

Building 1 gets the best crew and everyone’s full attention. The board’s job is to make sure Building 7 gets the same.

• Make the first building the standard. Complete it, walk it with the board representative or manager, settle any questions about details and cleanup, and then proceed. Problems are cheap to fix on one building and expensive on six.
• Get in-progress photos of deck, ice barrier and flashing for each building before they are covered.
• Close out building by building. Walk each one when it is finished, not once at the end when nobody remembers Building 2, and close its punch list before its final payment.

Warranties: Who Gets the Paper, and Who Keeps It

Every roof has two warranties: the manufacturer’s on materials and the contractor’s on workmanship. For attached housing the questions change.

• Whose name goes on the manufacturer warranty? The association or the individual owners? It should follow who owns and is responsible for the roof under the documents.
• Read the warranty terms for the actual ownership structure. Warranty length and coverage can differ based on who owns the roof, the property type and the manufacturer. Do not assume “lifetime” means the same thing for an individually owned attached unit and an association-owned building. Get the answer in writing from the current warranty document or the manufacturer’s representative, not from a brochure.
• Enhanced or system warranties usually require specific components, a credentialed installer and registration after the job. Ask for the registration confirmation. Northern Exteriors is a Malarkey Certified Pro Contractor, which lets us offer Malarkey’s enhanced warranty on qualifying roof systems. We install other major manufacturers’ systems as well.
• Workmanship warranty. Get the term in writing, along with who residents call if there is a leak in year three: the manager, the board or the contractor.
• Where the documents live. Boards turn over and management companies change. The closeout package belongs in the association’s permanent records, not in one board member’s personal email.

Money: What a Roofer Can and Cannot Tell You

How an association pays for roofs, whether from reserves, an assessment, financing, insurance proceeds or a mix, is a decision for the board with its manager, accountant and attorney. I do not give financial advice, and I would be wary of a roofer who does.

What a contractor can give the board is numbers to plan with: per-building pricing, phased pricing if phasing is on the table, unit prices for unknowns like decking, and an honest condition assessment of each building with photos. One practical note: material prices move and proposals expire. A bid from February is not a number for next spring.

If the Project Starts With Storm Damage

The June 19, 2026 storm is a current example. The National Weather Service documented hail larger than two inches in northern St. Paul, and the storm crossed Roseville and neighboring communities. A regional hail report does not prove damage on any particular building, and that is exactly the problem for a community with eight of them.

The first question is the same as always: what do the documents and the policy say? Some associations carry a master policy that covers building exteriors. In others, each owner insures their own unit, roof included. That decides who files a claim, and a contractor cannot answer it. The governing documents, the policy language and the insurance agent can. The policy controls what is covered and how the deductible applies. How any deductible or shortfall is shared among owners depends on the documents. Individual owners should ask their own agent how their policy treats association assessments.

What a contractor can do is inspect every building and document what is there: shingles, soft metals, gutters and siding, organized by building and by slope, with photos, so the association and its insurer are working from the same facts. We document conditions. We do not decide coverage and we do not promise outcomes.

Two things are specific to multi-building communities:

• An insurer may reach different conclusions on different buildings or slopes. What the policy owes is a policy question. What the community ends up looking like is a board question. Think about both before work starts.
• One signature on a townhome contract can mean thirty roofs, so these communities get worked hard after a storm. A board has every right to slow down, verify the contractor’s Minnesota license with the Department of Labor and Industry, confirm insurance and call local references.

If a claim is already open and dragging, this may help: why a slow claim is not a dead claim.

What I Would Want Settled Before an HOA Signs a Roofing Contract

The roofing itself rarely sinks one of these projects. These do:

• Nobody with authority can be reached while a roof is open. Work stops, or someone makes a decision they were never authorized to make.
• The scope was vague at the unit lines, the walls and the gutters. Every gray area becomes a change order or a shortcut.
• Residents found out the morning the dumpster showed up. The board takes the heat for the rest of the project.
• The money was not actually in place when materials were ordered. Assessments not yet collected, a loan not yet closed, insurance funds not yet released. A contractor cares about this as much as the board does.
• Bids were compared on price alone, and the low bid reused flashing and never looked in an attic.
• Nobody can find the warranty five years later.

Every one of those is preventable on paper, before the first shingle comes off.

Six questions to ask every bidder out loud

1. Where exactly does your scope stop at each unit line and wall?
2. What is in your decking allowance, and what happens at the first sheet past it?
3. Did you look inside any attics? What did you find?
4. What are you reusing?
5. Who will be on this property every day, and what is their cell number?
6. Can we see the resident notice you plan to send?

If a contractor cannot or will not put the answers in writing, that tells you what Building 7 is going to look like.

Frequently Asked Questions

Who pays for a townhouse roof replacement?

It depends on the association’s governing documents. In some Minnesota townhome communities the association is responsible for roofs and funds them through dues, reserves or assessments. In others, each owner pays for the roof over their own unit while the association sets the standards. After a storm, the documents and the policy language determine whether a master policy or individual policies are involved. Read the declaration first, and ask the association’s manager or attorney if it is unclear.

Does an HOA have to replace every roof at once?

Not necessarily. Some associations replace every building in one project for a consistent look and a single warranty start date. Others phase the work over several years based on roof condition and budget. What an association may or must do depends on its documents, its finances and the condition of each building. If the work is phased, holding one written specification across every phase protects appearance and quality.

Can individual townhouse owners choose different shingles?

Usually not freely. Even where owners are responsible for their own roofs, most associations control the approved shingle and color so the buildings match. On a continuous roof, mixing products also creates practical problems at the seam between units. Get written approval from the association before ordering materials.

How long does a multi-building townhouse roofing project take?

A detached home may be completed in a few days, while a multi-building project is usually measured in weeks. The real answer depends on the number and size of the buildings, crew size, the contractor’s schedule, weather, material delivery, city inspection timing and what turns up under the old shingles. A good proposal gives a start window, a building sequence and a plan for weather delays instead of one optimistic finish date.

What should an HOA compare besides price when reviewing roofing bids?

Scope first: tear-off, decking allowance and unit price, ice barrier, new versus reused flashing, ventilation, gutters, permits and the exact shingle system. Then how the job will be run: daily supervision, resident communication, staging, in-progress photos, change orders, lien waivers and warranty registration. Two bids are only comparable when they price the same written scope.
