WTI - Weatherproofing Technologies Incorporated

Weatherproofing Technologies, Inc. offers a
comprehensive inventory of roofing and general
contracting (GC) services to building owners and
facility managers.

In addition, our General Services team provides a wide range of roofing services to help keep roofs leak-free and facilities dry, extending their useful service life: Weatherproofing Technologies Canada provides these services in Canada.

Our commitment to roofing excellence extends from ensuring that roofing systems are installed correctly to keeping them functioning as expected through ongoing asset management designed to meet both sustainability
and financial goals.

Through our Construction Management Services (CMS) program, we can take managing roofing projects off your plate, and put experts in charge of the intensive, time-consuming, daily demands of administration, budgeting, scheduling, quality control and on-site supervision. Additional details of our program are available in our CMS brochure.

In addition, our unique Tremco Managed Assets program provides complete roofing and building envelope maintenance support while shifting the financial responsibilities to us.

If you would like to consult with a WTI specialist about our General Contracting services, contact your local Tremco Roofing representative.
