An exterior project at a single home is one owner's decision. At a condominium or HOA, it is a board decision that affects many households, a shared budget and a long list of people who all want to know what happens next. The roofs, gutters, siding and windows are also connected: water that gets past one of them usually shows up at another. Boards that plan the whole exterior early tend to have a smoother project, with fewer surprises on cost, fewer complaints from residents and a clearer paper trail.

This guide walks through the planning from the board's side of the table, from assessment to closeout. If you are also comparing contractors, our page on multi-family and HOA roofing, siding, windows and gutters includes a checklist of what a good proposal should contain.

Start With an Assessment of the Whole Exterior

Before anyone requests a price, the board needs to know what it is dealing with. For each building, gather the age of each component, past repairs, leak and overflow complaints by unit, and photos of visible wear. A professional evaluation turns those notes into a scope: what can be repaired, what needs replacing, and what else belongs in the project. Use the table below as a starting checklist.

Roofs

The roof usually drives the project, because a failing roof can damage everything under it. Pitched and flat roofs fail differently, and properties with low-slope sections need a contractor who works with those systems. See our flat and low-slope roofing page for what that involves. Ask the evaluation to cover flashing, ventilation and roof edges, not just the shingles or membrane.

Gutters and Gutter Guards

Multi-family buildings have more roof area, longer gutter runs and more downspouts than a single-family home. That makes drainage more important, and failures more visible: overflow stains siding, water pooling at walkways and entrances is a hazard, and ice at the eaves can drop onto paths below.

• Size and layout. Gutters and downspouts should be sized for the roof area they serve, with discharge directed away from foundations, walkways and parking areas.
• Coordinate with the roof. Gutters mount at the roof edge and fascia, so replacing them while the roof is open avoids doing the same edge work twice.
• Gutter guards. On tree-lined properties, guards reduce the leaves and needles that get into long gutter runs and can reduce how often high gutters need cleaning. They do not eliminate maintenance, and the right product depends on the roof, the gutters and the debris.

Siding and Exterior Walls

Siding does two jobs: it sets the look of the community, and it protects the walls. Rot at corners and trim, stains below windows and soft spots near the roofline are signs that water is getting behind it.

• Consistency. Many associations have exterior design guidelines for colors and materials. Check them before choosing a product, and specify the exact product, color and profile so later phases match.
• Material choice. Fiber cement and vinyl are the two common options, with different costs and maintenance needs. Our siding installation page compares them.
• Hidden conditions. Rot or damaged sheathing is often found only after the old siding comes off, so the proposal should explain how those conditions will be priced and approved. See siding replacement for what a tear-off involves.

Windows

Windows are tied closely to the siding, since their flashing and trim sit inside the wall. Replacing both together lets the flashing, weather barrier and siding be installed as one system.

• Who owns them. In some associations the windows are part of the building exterior, and in others they are the unit owner's responsibility. Your governing documents decide, so confirm this before defining the scope.
• Uniform or unit by unit. Decide whether the board wants matching windows throughout the community or will allow owners to choose within guidelines.
• Older buildings. Buildings built before 1978 may have lead-based paint on windows and trim, and federal rules require lead-safe work practices for renovation work. Building codes also set minimum egress openings for bedroom windows, so replacements should not reduce the clear opening.

See our window replacement page for more.

Decide Between Doing Everything at Once and Phasing the Work

Boards with several buildings face this choice, and there is no universal answer. It depends on the condition of each building, the reserves available and how much disruption residents will accept. If you phase the work, decide whether to go building by building, so each building gets everything in one pass, or trade by trade across the property.

Whichever approach you choose, have every building evaluated now. Even a phased plan works better when the board knows which components are the most urgent.

Funding and Approvals Come From Your Governing Documents

How a project is paid for and approved is set by your association's documents, not by the contractor. Check your master deed, declaration, trust or bylaws for spending limits, reserve fund rules, and when a unit-owner vote or special assessment is required, and ask the association's attorney if anything is unclear. Having a defined scope and a written proposal in hand makes those conversations concrete.

Request and Compare Proposals

Give each contractor the same information so the proposals can be compared fairly: the property address, the number of buildings and units, inspection reports, photos, any drawings, and the board's timing and budget considerations. Ask for written proposals with the roofing, gutters, siding and windows priced as separate line items, and compare the scope, materials, warranty terms and change-order process, not just the bottom line. Verify each contractor's Massachusetts license and registration, insurance and references. Ours are on our credentials page.

A Planning Timeline for the Board

The stages below are a general framework. Adjust them to your property and your governing documents.

Keep Residents Informed

Residents are usually most frustrated by surprises. A written notice before work begins should cover:

• What work is being done, and on which buildings
• Expected start and finish dates, and what happens if weather causes delays
• Daily work hours and when noise is likely
• Parking, driveway and walkway changes
• What residents should move or secure, such as patio furniture, planters and wall hangings
• When access inside units will be needed, if windows are part of the project
• Who to contact with questions, and how updates will be shared

Timing the Work in New England

Exterior work depends on the weather. Most large projects are scheduled for the milder months, and it helps to plan for contingency days. If residents have reported interior leaks or ice at the eaves, ventilation and insulation may be part of the cause. Our guides to stopping ice dams and to attic ventilation explain how that works, and both apply to multi-family buildings.

What the Board Should Keep at Closeout

• A final walkthrough record, with any punch-list items resolved
• The manufacturer's warranty for each product, such as roofing, gutters, guards, siding and windows, and the contractor's workmanship warranty, plus who administers each
• The approved scope, product specifications, colors and any signed change orders
• Confirmation that cleanup and debris removal are complete
• Contractor insurance certificates and any other closeout paperwork your management company or attorney requires

Questions Boards Ask About Exterior Projects

How early should an HOA start planning an exterior project?

Start as soon as the roofs, gutters, siding or windows show recurring problems or approach the end of their expected life, rather than waiting for an emergency. Early planning gives the board time to get inspections, define the scope, collect proposals, line up funding under your governing documents, and schedule the work for suitable weather.

Should roofing, gutters, siding and windows be done together or separately?

Doing them together can make sense because they meet at the same roof edges, walls and openings, and one contractor can coordinate flashing, trim and schedules. The board should still request a price for each part of the scope so it can compare proposals and decide what to do now and what to phase later.

Do gutter guards make sense for a multi-family property?

They can, particularly on tree-lined properties where long gutter runs fill with leaves and needles, because guards reduce the debris that gets in and can reduce how often gutters need to be cleaned. They do not eliminate maintenance, and the right product depends on the roof, the gutters and the type of debris, so plan them together with the gutter scope.

Who is responsible for windows, the association or the unit owner?

It depends on your governing documents. Some associations maintain the windows as part of the building exterior, while others make them the unit owner's responsibility. Confirm this with the documents or the association's attorney before defining the scope, and decide whether the board wants uniform windows across all units.

How can the board keep siding and windows consistent across buildings?

Specify the exact product, color and profile in the scope, check any exterior design guidelines your association has, and keep the specifications and samples on file. If the work is phased by building, the written specification lets later phases match the earlier ones.

Should an HOA do the whole exterior at once or one building at a time?

It depends on the condition of each building, your reserves, and how much disruption residents will accept. Doing everything at once can simplify pricing and keep the buildings consistent, while phasing spreads the cost but extends the disruption and leaves older components exposed longer. An inspection of every building helps the board decide.

Who decides what gets repaired and what gets replaced?

The board makes the decision, usually with advice from professional inspections and the management company. A contractor can evaluate the roofs, gutters, siding and windows and outline repair and replacement options, but the association's governing documents determine who has authority to approve the work and the spending.

How can the board keep residents informed during an exterior project?

Send a written notice before work starts that covers the scope, expected dates and weather contingencies, work hours, parking and access changes, and a single point of contact. If windows are included, say when access inside units will be needed. Follow up with updates if the schedule changes, and tell residents what to move or secure around their homes.

What should the board receive at the end of the project?

A final walkthrough with any punch-list items resolved, the manufacturers' and contractor's warranty documents for each product, a record of the approved scope and any change orders, confirmation that cleanup is finished, and any other closeout paperwork your management company or attorney requires.

Does winter work cause problems for occupied buildings?

Cold and snow can delay exterior work and limit which materials and methods can be used, so most large projects are scheduled for milder months. If work must be done in winter, it is often limited to what is needed to stop leaks until a full project can be scheduled.
