Water intrusion and building-envelope failures are not always visible at the point where damage appears.
Water may enter through roofing systems, exterior walls, flashing, windows, penetrations, and waterproofing transitions before traveling through concealed building assemblies and becoming visible elsewhere.
Summit Building Group combines extensive construction experience, specialized inspection training, investigative methods, and advanced diagnostic technology to evaluate complex building conditions and identify evidence-supported causes.
Our objective is to understand why a problem is occurring, not simply recommend repairs based on visible symptoms.
Recurring leaks, unexplained water damage, and unsuccessful repair attempts can indicate problems that require a more systematic investigative approach.
A visible ceiling stain or damaged interior wall does not necessarily identify the original point of water entry. Our investigations examine relevant building assemblies, construction details, drainage conditions, flashing, penetrations, and other potential pathways to develop and evaluate possible causes.
We combine field observations, available building history, appropriate diagnostic technology, and targeted testing to support our findings.
We investigate the underlying problem, not just the visible damage.
Forensic Water Intrusion Investigations are our most in-depth service, designed for problems that standard inspections and repeated repairs have not solved.
Our primary focus is water intrusion through roofing systems and exterior walls, the assemblies where most hidden leaks begin.
Interior symptoms can originate from exterior building-envelope deficiencies. We investigate interior water damage and moisture conditions when they help determine where water entered the building. This is an investigative service, not interior remodeling or interior wall repair.
Technology supports our professional judgment. It helps us document conditions and focus testing where it matters.
Aerial documentation of roof conditions, drainage patterns, roof transitions, and difficult-to-access building components.
Thermal imaging to identify temperature anomalies that may indicate conditions requiring further investigation and moisture verification.
Professional moisture measurement equipment, comparative readings, and systematic documentation of potentially affected building materials.
Evaluation of roofing systems, exterior walls, flashing, penetrations, waterproofing transitions, and suspected water entry pathways.
Controlled water testing and selective exploratory openings may be recommended when appropriate, authorized, and within the applicable scope of work. Infrared imaging identifies temperature differences and does not, on its own, confirm moisture or identify the source of a leak. Findings are verified with moisture measurement and other methods.
A systematic, documented approach from first conversation to final report.
Understand reported symptoms, previous repairs, weather conditions, and relevant building information.
Inspect the relevant roofing systems, exterior walls, drainage, flashing, penetrations, and building-envelope transitions.
Use appropriate investigative methods and diagnostic tools to evaluate suspected water entry pathways.
Record observations, photographs, measurements, test results, and relevant limitations.
Provide documented findings, identify likely contributing conditions, and recommend appropriate corrective measures or further investigation.
Where findings remain inconclusive, we clearly identify the limitations and the additional work needed.
Each service is built on the same foundation: construction knowledge, specialized training and documented evidence.

Clients receive a professional written deliverable, not simply a verbal opinion.
Depending on the investigation scope, our reports may include the items shown here, organized so owners, managers and their advisors can make informed decisions about next steps.
Some conditions cannot be fully determined without additional testing or access. When that happens, the report says so and explains what further evaluation would be needed.
Complex water intrusion problems require specialized investigative time, technical expertise, diagnostic equipment, and careful documentation.
Summit Building Group offers advanced diagnostic investigations as separately scoped, fee-based professional services. Clients engage us for our investigative knowledge, systematic approach, and documented findings.
Routine roof evaluations and pricing for defined repair or replacement work, offered through our roofing services.
Separately scoped investigations that may include field assessments, diagnostic testing, photographic documentation, technical reporting and recommendations.
When offered, repair and construction work is proposed separately after the investigation, based on the documented findings.
Our investigations are led by real field experience and verified credentials.
We are pursuing additional wall and building-science education to expand our technical capabilities. Summit Building Group does not provide licensed engineering services. The Haag HCI-C credential is a commercial roof inspection qualification.
Describe what you are seeing and what has been tried. We will discuss the issue and propose an investigation scope before any fee-based work begins.
Advanced diagnostic investigations are separately scoped, fee-based professional services. After reviewing your request, we will discuss the problem with you and confirm the investigation scope and fee before any work begins. Any corrective repairs are proposed separately.
Answers for property owners, managers and buyers.
Building diagnostics is the systematic investigation of building conditions, with a focus on water intrusion through roofing systems and exterior walls. We combine construction knowledge, field observation, diagnostic technology and documentation to identify evidence-supported causes.
Yes. Advanced diagnostic investigations are separately scoped, fee-based professional services. We discuss the problem and agree on the scope and fee before work begins. Standard roof assessments and construction estimates are offered separately through our roofing services.
Infrared thermography identifies temperature differences that may indicate conditions worth investigating. It does not, on its own, confirm moisture or identify the source of a leak. We verify findings with moisture measurement and other investigative methods.
Our goal is to identify evidence-supported causes, but some conditions cannot be fully determined without additional testing, access or exploratory openings. When findings are inconclusive, our report explains the limitations and the additional work needed.
No. Summit Building Group is a licensed construction contractor. Our investigations draw on construction experience, specialized inspection training and diagnostic technology. We do not provide licensed engineering services.
When offered, corrective construction is proposed separately after the investigation, based on the documented findings.
