Building envelope study and inspection services

A building envelope study is a check-up for your building. We inspect your roof, walls, siding, windows, doors, and decks to find out how they’re performing, what’s causing any damage, and what needs attention first. You get a clear record of your building’s condition before you spend money on repairs.

Your building shouldn’t leak. After you work with us, it won’t.

What is a building envelope study?

Why a reserve study isn’t enough

Think of it as an annual physical for your building

Many owners, associations, and managers assume their reserve study will tell them how their building is performing. It won’t. A reserve study estimates when to budget for replacements. It doesn’t show what’s happening behind your siding or under your roof. Staying on top of your building’s health takes regular inspection of the building envelope, the barrier between indoors and outside.

Like putting off a doctor’s appointment, putting off an inspection can turn a small, inexpensive fix into a major repair. Regular inspections help you avoid surprise, big-ticket repairs and protect your property’s value.

Choose the right level of inspection

Not every building needs the same depth of inspection. We offer three levels, and each goes deeper than the one before it. We’ll recommend the level your building actually needs.
Level 1

Visual Inspection

A quick screening of your building or a specific area, like your roofs or decks. We identify potential problem areas and help you set priorities.

Best for: a first look, a single concern, or deciding whether a deeper inspection is needed.

Level 2

Building Envelope Inspection (Envelope Study)

A detailed visual inspection of your building’s exterior systems: walls and siding, roof, windows and doors, decks, and, where needed, garages and interior areas where residents have reported damage.

Best for: understanding your building’s overall condition, documenting problems before a warranty ends, or planning major repairs.

Level 3

Evaluation and Testing

When a visual inspection can’t confirm what’s happening inside your walls or under your roof, we test. This can include water testing, infrared moisture scans, and small, controlled openings in the wall or roof to see the hidden layers.

Best for: confirming the source of a leak, measuring hidden damage, or supporting a repair design or claim.

Inspections and testing for specific concerns

Warranty inspections

Newer buildings often have defects that aren’t visible yet. A warranty inspection documents problems while your builder is still responsible for fixing them.

Roof assessments by a Registered Roof Consultant

We evaluate flat and sloped roofs, including TPO, EPDM, built-up, metal, and shingle systems. You’ll learn the roof’s condition, how much useful life it has left, and whether it needs repair or replacement.

Leak inspections

Sometimes water shows up far from where it gets in. We trace a leak to its actual source, so you pay to fix it once instead of patching symptoms.

Water testing for windows, decks, and roofs

We spray windows under controlled conditions (following the industry standard ASTM E1105) and flood or dye test decks,
roofs, and planters to see exactly where water gets through.

Infrared moisture scans

Infrared cameras detect hidden moisture behind walls and under roofing without opening anything up.

Attic, crawlspace, and deck inspections

Problems often start in the places no one looks. We check ventilation,moisture, and structural condition in attics and crawlspaces, and waterproofing and railings on decks.

What to expect

1

A free conversation

Tell us what’s going on, and we’ll recommend the right level of inspection.

2

Document review

We review any maintenance history, previous reports, and building plans you have.

3

Site visit

We inspect your building on foot and, when helpful, by drone. If we find something urgent, we tell you right away rather than waiting for the report.

4

Your report

You receive a written report with photos, findings, and recommendations.

5

Review with your Board

We walk through the findings with you and answer questions.

A report your board can understand and act on

  • A plain-language summary of what we found
  • A site map showing where we inspected
  • Findings organized by building system (walls and siding, roof, windows and doors, decks, and other areas), each with numbered, captioned photos
  • Recommendations sorted by urgency: immediate concerns, short-term items, and long-term planning
  • Clear next steps, such as whether more testing is needed
  • An explanation of what the inspection covered and what it didn’t, so you know exactly what the findings mean

Not sure if you need an engineer? Start with an inspection.

Many Boards assume they need a structural engineer or other specialist right away. Most don’t. A J2 inspection identifies what’s actually wrong and whether specialized expertise is needed. When a project needs a licensed architect or engineer, an industrial hygienist, or a hazardous materials survey, we bring in trusted partners and manage the process for you. You get one point of contact and only pay for expertise your project needs.

Our building consultants know building codes and industry standards, and we’ve spent 20 years and more than 3,300 projects evaluating why buildings fail.

Frequently Asked Questions

What is a building envelope study?
A building envelope study is an inspection of your building’s roof, walls, windows, doors, and decks to see how well they keep weather out. It gives your Board a record of your building’s condition and a prioritized list of what needs attention.
What's the difference between a visual Inspection and a Building Envelope Inspection?

A Visual Inspection is a quick screening that identifies potential problem areas and priorities. A full Building Envelope Inspection looks at every major exterior system in detail and documents each finding with photos and recommendations.

Will you need to open up our walls?
Usually not at first. Our inspections start with visual, non-invasive observation. We only recommend small, controlled openings when we need to confirm hidden damage or the cause of a leak.
Do you need access to individual units?
Sometimes. We usually inspect a sampling of units, focusing on those where residents have reported leaks or damage. Your management team helps coordinate access.
Do we need an engineer?
You only need a structural engineer when you have a structural problem. We diagnose leaks, which can turn into structural problems if they aren’t fixed. We’ll tell you if your project needs an engineer, and we’ll bring in a licensed partner when it does.

After the diagnosis: designing the fix

Once we know what’s wrong, the next step is designing a repair that lasts.
