Wetherholt and Associates, Inc. was founded in 1984 to serve the construction industry by assisting in resolving water intrusion problems. Specifically, we specialize in roofing, waterproofing, and building envelope trouble shooting and problem solving. Additional services include concrete consulting, wood decay investigations, interior moisture (condensation and ventilation) investigation, and alternative dispute resolution as “expert mediators”. Clients include several major school districts, manufacturing companies, and municipal and state government departments.

The majority of our work is for commercial, institutional, and public sector clients whose properties require careful and prudent management of resources, both monetarily and functionally. We are familiar with almost all types of roofing, waterproofing, and building cladding. We have the resources to investigate those with which we might be unfamiliar.

Wetherholt and Associates, Inc., consists of Ray Wetherholt, P.E., RRC/RWC/REWC/RBEC, Professional Engineer and Registered Roofing, Waterproofing, and Exterior Wall Consultant; Senior Field Engineers: Don Davis, RRC/RWC/REWC/RBEC; Bob Card, RRC/RWC/REWC/RBEC/GRP; Jeorge Hopkins, RRO/RRC/RWC; Mike Caniglia, RRC/RRO/RWC/REWC/RBEC; and Pravat Sripranaratanakul RRO/RRC. Field Engineers: Jose Laurean, RRO, experienced roofing, waterproofing, and building envelope application inspectors, and support staff.

Depending upon the project, we are retained by the design professional or work directly for the owner, to prepare or review waterproofing, roofing, and reroofing specifications, drawings and details as part of the building envelope. Once the documents are reviewed, we assist with the prebid meeting and issuance of addendum. Once the bids are received, they are reviewed, and awarded as appropriate. We then conduct the preroofing meeting with the owner, architect, contractor, and manufacturers to be sure everyone understands the project scope, and resolve concerns which may come up.

Once waterproofing or roofing is started Wetherholt and Associates, Inc., inspectors are on site to verify the work conforms to the contract and assist in avoiding conflict between the specifications and the actual conditions. The inspectors are familiar with most of the waterproofing and roofing systems on the market today, and the depth of Wetherholt and Associates, Inc., experience allows us to respond quickly and accurately to most questions or concerns.

We are capable of determining the types of roof and waterproofing systems in place, performing moisture surveys, determining leak sources, and generating CAD details.

Unfortunately not all projects are successful, and result in disputes between the parties. Our goal is to be fair and keep all parties out of litigation. However, we have been retained by litigants to assist them as expert witnesses.

In summary, we are interested in listening to our clients needs and serving them in an ethical and economically justified manner to obtain a result meeting their needs. If you have any questions, or if we may be of service, please do not hesitate to call us at (425) 822-8397.
