As the protective exterior, an effective roof assures that a building can operate as it was designed. However, should a leak occur, the integrity of the building is compromised. Business and production are jeopardized. Products can be damaged. Building components may be rendered ineffective. A leaky roof invites a multitude of problems!

The roof engineering specialists at Raymond Engineering are experts at evaluating any problems and providing sound solutions. Our roof evaluation procedures use the latest technology – Roof Pro® – to manage your roofing assets.

Determining the effectiveness of your existing roof system and associated components is our primary objective. We evaluate all aspects of your roof construction. Our first step is to conduct a visual inspection of roofing components:

• Membrane
• Flashings and metal flashings
• Drainage facilities
• Walls above roof level and above grade
• Equipment (to determine watertightness)

Upon completion of our visual inspection, we carefully document any leaks that may indicate other concerns with building envelope performance. In addition, we measure the roof and take photographs of the existing conditions.

Non-Destructive Surveys

Non-destructive moisture surveys are especially advantageous in those situations where selected repairs may be beneficial to extending the overall performance of the roofing system. Our engineers have considerable thermography experiences and can conduct infrared and electrical capacitance surveys.

• Infrared Moisture Surveys

Infrared testing is a non-invasive process for identifying areas where moisture may have infiltrated the roofing assembly. The infrared camera captures the thermal image of the  roof system which may identify areas of moisture infiltration. Infrared surveys can often identify moisture in the roof membrane before it becomes a major problem.

• Electrical Capacitance Surveys

Electrical capacitance moisture meters can measure the electrical resistance within a roof system and detects changes in roofing conditions that may indicate trapped moisture.

Survey Findings

Upon completion of our field activities, we provide our clients with a comprehensive report of our findings. This report includes:

• Written descriptions of our visual observations.
• Photographs of selected conditions.
• Roof plan.
• Results of any roof opening and/or laboratory analysis.
• Infrared survey results, (if part of the requested work).
• Electrical capacitance survey results, (if part of the requested work).
• Executive Summary.
• Cost estimates for the repair and/or replacement of roofing systems and/or associated components.
