Protecting Buildings from Water Intrusion, Structural Deterioration, and Energy Loss

The building envelope—including the roof, exterior walls, windows, waterproofing systems, and structural transitions—is the primary barrier protecting a building from weather, moisture, air infiltration, and environmental damage.

When envelope systems fail, the results can include water intrusion, structural deterioration, mold growth, interior damage, and increased maintenance costs.

Our Roof & Building Envelope Division provides professional inspection, diagnostic testing, and engineering evaluation services to identify failures, determine causes, and develop practical repair solutions that restore performance and protect the building.

Our Roof & Building Envelope Services

Roof Condition Inspections

Roof systems are one of the most critical components of a building envelope. Over time, exposure to sunlight, rain, wind, temperature changes, and mechanical wear can cause deterioration and leaks.

Our engineers evaluate all major roof system components, including:

roofing membranes
flashing systems
roof penetrations
insulation layers
drainage systems
rooftop mechanical equipment supports
parapet and coping conditions
roof deck structure

Roof condition inspections help determine whether a roof is functioning properly, approaching the end of its service life, or requiring repair or replacement.

Leak Investigation and Water Intrusion Analysis

Water intrusion is one of the most common and costly problems affecting buildings. Identifying the true source of a leak can be difficult because water often travels through concealed paths before appearing inside.

Our engineers perform detailed leak investigations to determine the origin of moisture problems and evaluate the performance of roof and envelope systems.

We investigate:

recurring roof leaks
moisture infiltration through walls or windows
water penetration at balconies and terraces
flashing failures
drainage problems
sealant and joint deterioration
moisture damage to structural components

Understanding the source of water intrusion allows owners to correct the root cause rather than repeatedly repairing symptoms.

Building Envelope Inspections

The building envelope includes all exterior components that separate the interior environment from outdoor conditions.

Our building envelope inspections evaluate the condition and performance of:

roof assemblies
exterior walls and cladding
windows and glazing systems
waterproofing membranes
sealants and expansion joints
balconies and terraces
flashing systems
transitions between building components

These inspections identify weaknesses in the building enclosure that may lead to moisture intrusion, structural deterioration, or energy loss.

Waterproofing and Moisture Protection Evaluation

Waterproofing systems play a critical role in protecting buildings from long-term damage. When these systems deteriorate or fail, water infiltration can damage both structural and interior elements.

We evaluate waterproofing performance for:

roof membranes
terrace and balcony waterproofing
foundation waterproofing
podium deck systems
expansion joints
below-grade structures
plaza decks
wall and window interfaces

Our engineers determine whether waterproofing systems are functioning as intended and recommend repairs or upgrades where needed.

Building Performance Testing

When building envelope problems are suspected but not clearly visible, diagnostic testing can help determine how the building performs under real conditions.

Our building performance testing services may include:

water intrusion testing
infrared thermal imaging
moisture detection
air infiltration testing
roof membrane testing
enclosure performance diagnostics
leak detection analysis

These tests help identify hidden moisture problems, insulation deficiencies, and areas where envelope systems are failing.

Roof Structural Evaluations

Roof systems often support mechanical equipment, solar installations, green roof assemblies, and other structural loads.

Our structural engineers evaluate:

roof deck condition
structural framing
load capacity
support systems for rooftop equipment
structural distress or deflection
deterioration caused by water infiltration

Structural evaluation ensures the roof system remains safe and capable of supporting current and future loads.

Roof Replacement and Repair Planning

When deterioration reaches a point where repair or replacement is required, our engineers assist owners in planning and implementing effective solutions.

Our services include:

roof repair recommendations
roof replacement planning
budgeting and cost analysis
specification development
contractor coordination
construction observation and quality assurance

Proper design and planning help ensure that new roof systems perform as expected and provide long-term durability.

Types of Buildings We Evaluate

Our Roof & Building Envelope Division provides services for a wide range of property types, including:

condominium and residential buildings
commercial office buildings
hotels and hospitality facilities
hospitals and healthcare facilities
universities and educational campuses
parking structures
municipal buildings
mixed-use developments
industrial facilities

Each building type has unique envelope performance requirements and maintenance challenges.

Common Envelope Problems We Identify

Our inspections frequently reveal issues such as:

roof membrane deterioration
flashing failures
sealant deterioration
improper roof drainage
moisture intrusion through walls
window leakage
waterproofing failure
deteriorated parapets and coping
condensation problems
insulation deficiencies

Addressing these issues early can prevent extensive structural damage and interior repairs.

Our Inspection Process

1. Preliminary Review

We begin by reviewing available construction drawings, roof history, prior repairs, and known problem areas.

2. Field Inspection

Our engineers perform a comprehensive site inspection of the roof system and building envelope components.

Depending on the building, inspection methods may include:

roof surface evaluation
close-up facade observation
moisture detection tools
infrared scanning
visual examination of envelope transitions

3. Diagnostic Testing

When necessary, testing may be performed to evaluate the performance of roofing and enclosure systems and confirm the source of leaks or deterioration.

4. Engineering Analysis

Observed conditions are analyzed to determine the causes of envelope failure and the potential impact on the structure and building performance.

5. Reporting

Clients receive a detailed engineering report documenting:

observed conditions
photographs and documentation
areas of concern
causes of failure
recommended repairs or corrective measures

Why Building Envelope Inspections Matter

Building envelope problems often develop gradually and may remain hidden until damage becomes severe.

Regular evaluation helps owners:

prevent water intrusion damage
extend roof and envelope life
reduce repair costs
maintain energy efficiency
protect structural components
improve occupant comfort
protect property value

You should consider an inspection if:

recurring leaks occur
the roof is approaching the end of its service life
moisture stains appear inside the building
roof equipment installations are planned
waterproofing systems show deterioration
energy performance is declining
the building has not been evaluated in several years
