Roof Replacement for Condominiums: 7 Costly Mistakes
A roof replacement can look straightforward on paper: hire a roofing contractor, remove the existing system, install the new roof, obtain the warranty, and close the project.
In reality, it is rarely that simple.
When planning a roof replacement for condominiums, the roofing contract may represent only part of the project's true cost and complexity. Once construction begins, hidden conditions, deteriorated concrete, wet insulation, material storage, resident access, manufacturer requirements, drainage issues, and unexpected repairs can quickly affect both the budget and schedule.
For Property Managers, the challenge is even greater. The building still needs to operate while construction is taking place, residents need information, contractors need access, the Board needs updates, and financial decisions must continue to be made throughout the project.
Many expensive problems can be avoided if the right questions are asked before the first section of roof is removed.
Here are seven mistakes Property Managers and Condominium Associations should avoid.
1. What Property Managers Should Know About Roof Replacement for Condominiums
One of the most expensive surprises in a roof replacement is often something nobody can see from the surface.
What is actually underneath the existing roofing system?
Before establishing the final budget, the project team should understand the existing roof assembly as much as reasonably possible.
That includes:
Existing roofing system and number of layers
Type and thickness of insulation
Condition of the insulation
Potential moisture within the roof assembly
Existing roof deck or structural substrate
Drainage conditions
Existing penetrations and equipment
The insulation system deserves particular attention.
If existing insulation is wet, damaged, deteriorated, or incompatible with the proposed roofing assembly, portions of it—or potentially the entire system—may require replacement.
That can have a substantial impact on the project cost.
This is why pre-construction investigation is so important. Depending on the project, roof cuts, moisture surveys, infrared testing, existing drawings, previous repair records, and other investigations can help the project team better understand what may be encountered during demolition.
You may not eliminate every unforeseen condition.
But there is a significant difference between an unforeseen condition and a condition that simply was not investigated.
2. Hiring a Qualified Roofer—but Forgetting About the Manufacturer
A contractor can be licensed, experienced, and competitive and still not be the right contractor for the roofing system being specified.
One question should always be asked during contractor selection:
Is this roofer currently approved or certified by the roofing manufacturer?
This can directly affect the warranty available to the Association.
Depending on the roofing system and warranty program, manufacturer-approved contractors may be required to obtain certain enhanced or extended warranties.
But verifying certification is only the beginning.
Before construction, the Association should clearly understand:
Who is issuing the warranty?
How many years does it cover?
What components are included?
What are the exclusions?
What installation requirements must be followed?
Are manufacturer inspections required?
What documentation is required before the warranty is issued?
And there is another step that should not be overlooked:
Get the manufacturer's representative involved during construction.
When required by the selected system or warranty program, the manufacturer's representative should visit the property at appropriate stages of installation—not simply after the roof is complete.
Those visits provide an opportunity to identify installation issues while they can still be corrected and help confirm that the completed system meets the requirements for the intended warranty.
The goal is not simply to receive a warranty document at the end.
The goal is to make sure the Association receives the warranty it expected to receive when the contract was awarded.
3. Budgeting for a “Roof Replacement” Instead of the Real Project
This is where many budgets fall short.
The Association budgets for roofing work.
Then demolition starts.
Suddenly, deteriorated concrete is discovered around a drain. A parapet requires repair. An equipment curb is deteriorated. Reinforcing steel is exposed. Portions of the substrate need restoration before the roofing contractor can continue.
Now the question becomes:
Who pays for it?
A roof replacement—particularly on an older building—may involve much more than roofing.
Potential associated work can include:
Concrete restoration
Reinforcing steel treatment
Roof deck repairs
Parapet repairs
Equipment curb repairs
Drain modifications
Penetration repairs
Waterproofing transitions
Mechanical or electrical coordination
These conditions should be discussed during pre-construction and, when appropriate, incorporated into the budget through allowances, unit prices, or contingency funds.
For example, if concrete deterioration is reasonably anticipated, establishing unit prices before construction can provide the Association with a much better mechanism for controlling additional costs when repairs are discovered.
A realistic project budget should account for the building that exists, not only the new roofing system shown on the drawings.
4. Allowing Mobilization Without an Approved Logistics Plan
Where will the contractor store the roofing materials?
Where will the dumpster go?
Where will workers park?
How will materials reach the roof?
Will a crane be required?
Which areas will residents lose access to?
These questions may seem operational—until construction begins without answers.
A Construction Logistics Plan should be reviewed before major mobilization.
Depending on the property, it should identify:
Material storage areas
Equipment and staging locations
Dumpster locations
Crane and hoisting areas
Loading and unloading zones
Contractor access routes
Worker parking
Temporary protection
Restricted areas
Resident circulation
Emergency and fire-access routes
Material storage requires particular attention.
Roofing projects may involve adhesives, primers, solvents, fuels, propane, and other products subject to specific storage and safety requirements, including potentially flammable materials.
The Association should know what is being stored on its property, where it will be stored, and how the area will be controlled.
The Logistics Plan also becomes an important communication tool.
Instead of telling residents, “Roof construction starts Monday,” Property Management can explain where the contractor will operate, which areas will be affected, where equipment will be located, and what residents should expect.
Good logistics are not simply about contractor convenience.
They are about keeping an occupied property functioning safely while construction takes place.
5. Starting With a Contract—but Without a Real Project Roadmap
A contract may say the project has 180 days to reach completion.
That does not tell the Property Manager what should be happening on Day 30, Day 60, or Day 120.
Before construction begins, the Association should have two things:
A clearly defined Scope of Work and a Baseline Schedule.
The scope should establish responsibilities for the major components of the project, including items such as insulation, drainage, flashing, penetrations, equipment curbs, repairs, temporary protection, testing, inspections, warranties, and closeout.
The schedule should then translate that scope into a sequence of activities and milestones.
For example:
Mobilization → Demolition → Existing Condition Repairs → Roofing Installation → Manufacturer Inspections → Testing → Punch List → Closeout
Once construction begins, the schedule becomes a management tool.
Is the contractor where they said they would be?
Are material deliveries affecting progress?
Is another trade delaying roofing installation?
Has an unforeseen condition affected the critical path?
Without a baseline, everyone may know that the project is “taking longer,” but it becomes much harder to establish why.
6. Treating Change Orders and Payment Applications as Paperwork
A Change Order is not just a document requiring a signature.
It is a financial decision.
Before recommending approval, the project team should be able to answer:
Why is this additional work?
Was it included in the original contract?
What condition triggered it?
Who verified the condition?
What quantity is being charged?
How was the price calculated?
Does it add time to the project?
Where applicable, supporting documentation should include photographs, field reports, measurements, drawings, proposals, unit prices, labor and material breakdowns, and review by the appropriate Design Professional.
The same discipline should apply to payment applications.
If a contractor reports that an activity is 80% complete, the question should not simply be whether the math on the payment application is correct.
The question should also be:
Is the work actually 80% complete in the field?
Physical progress should be compared with financial progress through field observations, installed quantities, photographs, inspection records, stored-material documentation, the project schedule, and the Schedule of Values.
On a multimillion-dollar project, even a relatively small difference between reported and actual progress can represent a significant amount of the Association's money.
7. Waiting Until the Roof Is Finished to Think About Closeout
The roof may be complete.
That does not necessarily mean the project is complete.
Before final payment, the Association may still need manufacturer documentation, warranties, final inspections, permit closure, testing records, punch-list completion, as-built information, and other contract closeout documents.
Trying to collect all of this after the contractor has demobilized can be difficult.
Instead, closeout should be managed throughout construction.
The project file should progressively collect:
Inspection reports
Manufacturer field reports
Testing documentation
Product approvals
RFIs
Approved Change Orders
Field reports
Progress photographs
Punch-list records
Permit documentation
Final inspection records
As-built information, when required
Contractor warranties
Manufacturer warranties
One document deserves special attention:
The final roofing manufacturer warranty.
The Association should confirm that all required inspections, corrections, documentation, and administrative requirements have been completed before the project is considered fully closed.
A roof replacement should not end with:
“The contractor finished.”
It should end with:
“The Association has received what it contracted and paid for.”
The Most Expensive Mistakes Often Happen Before Construction
The common thread behind these seven mistakes is simple:
Roof replacement is not just a roofing activity. It is a construction project that requires planning, coordination, financial control, documentation, and oversight.
For Property Managers, that can mean managing the roofing contractor while simultaneously coordinating the Board, residents, Design Professionals, manufacturer representatives, inspectors, vendors, and normal building operations.
That is where having an experienced Owner's Representative / Construction Project Manager can provide significant value.
The Owner's Representative helps connect the different pieces of the project—scope, schedule, costs, field conditions, Change Orders, payments, documentation, coordination, and closeout—while representing the Association's interests throughout construction.
At BRS Building Restoration Services, we help Condominium Associations and Property Managers manage complex restoration and capital improvement projects from pre-construction through final closeout.
Because a successful roof replacement should not be measured only by whether the building received a new roof.
It should also be measured by whether the Association received the right roof, the right warranty, proper documentation, controlled costs, and a project that was properly managed from beginning to end.
