Structural Inspections Puerto Rico & Roof Inspections
Structural inspections Puerto Rico provides roof damage caused by hurricane force winds, rain for any roofing system including flat roof, and sloped roofs. It is important to monitor the condition of the roofing system through proper inspection at frequent time intervals to discover damage to the roof. Small imperfections can be corrected with minimal maintenance. No roof system can be expected to give long term performance without some attention and maintenance. Too frequently, roofs are forgotten until a leak develops. Most problems begin in a small way and if left undetected, develop into a more expensive need for repairs, or in the extreme, need replacement of the roof.
A roof Inspection consists of the following elements:
Visual inspection of the damages sustained during hurricane, storms and high winds
Torn out roofing elements inspections
Roof Moisture surveys using electrical impedance methods for leaking or torn off roofs..
Observations and Findings: Results of the investigation.
Drawings:CAD drawings showing location of additional suspected moisture.
The summary of inspections and professional engineers recommendations.
Our structural forensic roof inspections techniques include
1. Principles of Electrical Capacitance/Infrared
With the electrical capacitance and Infrared, roofs can be scanned with a highly sophisticated infrared camera to detect and accurately map sub-surface moisture, thereby determining whether a portion or all of the roof requires replacement. Unlike other non-destructive techniques, infrared thermal scanning assesses every square inch of the roofing including vertical flashing. This results in a comprehensive view of the roof s condition with the possibility of error minimized.
The moisture survey & roof inspections are conducted by using EC equipment over the roof surface.
2. Characteristicts of Moisture in Roofing.
Infrared techniques pinpoint the moisture entry points from the interior, exterior, or from roof leaks. The absorption characteristics of various types of building materials are of particular interest. With porous material, moisture generally penetrates from the surface down; the greatest amount of water is found near the surface traveling along and dispersing into the porous material. In colder regions a potential condensation problem exists. The insulation is often protected by a vapor barrier located as near as practical to the warm side. As long as the vapor barrier is maintained at a temperature above the dew point, condensation can be completely forestalled. If water vapor can penetrate into the roof because of a poorly installed vapor barrier, it will migrate to the cold face, condense and often, be absorbed by the insulation or other absorbent materials.
The characteristics of various types of roofing materials raises a similar interest. Different roofing materials have varied moisture absorption characteristics. With porous material, moisture generally penetrates from the surface down. The greatest amount of water is found near the surface traveling along felts and dispersing into the insulation. The quantity of moisture, its form, and location within the assembly, and the water absorption.
3. Technical Approach
When an abnormality is identified as wet, (usually noted as a darker colored area), it is marked with paint and is photographed for future reference. The location of this area of sub-surface moisture is noted on the roof map which accompanies the report. Findings were not confirmed by further tests.Under a clear sky during the day, the roof acts as a large thermal collector and can approach 160 degrees Fahrenheit. Insulation laden with sub-surface moisture absorbs this radiation and acts as a reservoir to regenerate the heating of the membrane after the solar affect has dissipated. The affect of wet and dry material on the surface temperature of the roof is also a result of emissive cooling of the roof surface as much as 15 degrees Centigrade below ambient. In cooler weather, the introduction of moisture reduces the R-value of the assembly producing thermal bridges. These thermal bridges are localized warm zones which also produce images on the Thermogram.
