Roof Engineers North Carolina

Our roof engineers North Carolina can inspect and perform roof inspections on any roof system including concrete roofs, gravel and shingled roofs. After hurricanes, or natural disasters including lightening strikes the roof may get damaged. That is where we send our professional engineers and inspectors to do a thorough inspections of roofing and intent of damages for insurance claim purpose and repairs.

We also perform various structural roofing inspections including initial tig-tag , structural in progress and structural final inspections for shingled, tile roofs. We also perform roof static uplift test TAS-105, TAS-106, Bell Chamber (TAS-124), Thermal Imaging etc. Various Services are performed and a Sealed and Signed report is prepared for the client.

We also perform structural roofing inspections for all shingle, metal & clay tile or concrete tile roofs by roof engineers North Carolina chapter 15. please call for our services.

INSPECTION PROCEDURES

The starting point of the Inspection should be the interior of the building by roof engineers north carolina. The interior walls and ceilings should be checked for signs of water staining. After inspecting the interior by a roof engineer  thorough inspection of the exterior walls should be made along with the roof system.

The following roof components should be inspected:

Flashing: These are the protection for the membrane termination and often provide a waterproof cover at the membrane termination. These include Counter- flashing, expansion joint covers, copings and flashing at walls and curbs. A variety of problems may occur at these vulnerable locations by roof engineers North Carolina,  roof engineers north carolina, Jacksonville NC, Raleigh, North Carolina,Texas, Florida as well as Tampa, Orlando & Ft. Lauderdale.

Penetrations: These are pipes, drains, vents, stacks and other items that penetrate the roof membrane. These MUST be flashed properly to assure a watertight roof system by roof engineers.

Field Membrane – What to look for:

· Open seams excessive blisters, wrinkles, ridges or areas of non-adhered membrane.
· Worn spots holes or deteriorated areas of the membrane by roof engineers north carolina.
· Deteriorated, areas of surface coating on the membrane.
· Adequate, drainage and ponding problems of the membrane.
· Areas around rooftop equipment that may have been degraded by leaks or spills or punctured by dropped equipment parts.

If you discover that you have a sag in the roof of your home or building you are probably wondering what caused it and how it should be fixed. Many times sags in a roof are due to excessive deflection or a break in one or more of the structural roof members caused by some type of overload. In Colorado roofs can become overloaded with snow drifting on lower roofs that intersect upper floor walls. In some instances, roof members can deflect or break when they are temporarily overloaded with stacks of asphalt shingles or tiles during re-roofing. Older roofs may experience noticeable “creep” deflection which is a phenomenon where structural wood elements “relax” over time and experience long term permanent deflection under a sustained load. 

Roofs can also sag when the attic is not adequately vented by roof engineers north carolina. Wood framing can experience significant expansion and contraction under changing temperature and humidity conditions that occur within the attic throughout the year. Wood members that have higher moisture contents typically experience a higher magnitude of long term creep deflection. If the roof is constructed with pre-manufactured trusses the connector plates can become loose over time as the wood containing the embedded plate teeth expands and contracts. If the connector plates pull loose then the connected truss members may pull out of the joints causing the truss to deflect. Loose plates can also result in load transfer to other members of the truss which can lead to cracks, splits or breaks in a truss member. 

Mechanically pressed metal connector plates can carry a surprising amount of force but even very small gaps between the plates and the wood surfaces significantly reduces the holding capacity of the plates.
