what we do

Haag is an IAS Accredited Testing Lab. See our complete list of testing standards, or learn more about our testing services below.

Haag is the leading authority for research, development, and materials testing in the roofing industry. Since we established our laboratory in 1963, we have published numerous benchmark studies and disseminated other research data vital to professionals in the manufacturing, construction, insurance, and legal fields.

Clients commission Haag to conduct turnkey studies to and develop data for their in-house projects, even long-term studies using data compiled over a period of years. Our engineers and technicians combine their extensive education and field and laboratory experience to develop tests that duplicate real-world operating environments or incident conditions.

Haag Research & Testing now offers the HRT Quality Control Program (HRT-QCP). Manufacturers can have their roofing products laboratory tested  in accordance with IAS Accredited Standards to achieve an impact class rating or a wind rating, and have their products entered into Haag’s Quality Control Program.

Areas of Expertise


Laboratory technicians examine built-up roofing, modified bitumen roofing, or asphalt shingles for hail-caused damage, then asphalt is chemically removed, and individual reinforcements are examined for hail-caused fractures or strains.


Haag analyzes single-ply roofing samples (PVC, TPO, EPDM, and others) with a microscope and using high intensity light to find fractures.  


Haag’s IBL-7 impacts roofing and other materials with simulated hailstones (FM 4473).


Haag’s heat flow meter can measure R-values (or resistance to conductive heat flow) of insulation (ASTM C518). 


Haag is accredited by IAS to test solar panels for impact resistance to simulated hailstones (IEC 61215-2 and FM 4478).


Haag’s Wind Simulator can generate wind speeds of up to 170 mph to tests the response and resistance of materials to wind forces (ASTM D3161).

Water Column leak Testing

Haag uses water column testing to determine the response and resistance of a particular material to water intrusion (ASTM D7281).

Vacuum Uplift Testing

Haag tests the resistance of roofing materials to wind pressure using vacuum uplift testing (FM 1-52).

Steel Ball Impact Testing

Haag’s AccuDrop impacts materials with steel balls in accordance with UL 2218.

Large & Small Missile Testing

Haag launches small missiles into building materials to simulate airborne debris impacts.


Haag’s Forensic Testing laboratory is located at our U.S. headquarters near Dallas, Texas. Our testing services support our clients and Haag’s other service areas throughout the United States, Canada, Puerto Rico, and beyond.
