WTI General Contracting

General ContractingWTI (Weatherproofing Technologies, Inc.), an ISO 9001:2000 certified company, offers a comprehensive inventory of roofing and general contracting (GC) services to building owners and facility managers in the United States. 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. We will ensure that you know what roofing assets you have and their condition through our extensive inventory and condition analysis, manage your budget wisely and keep your roofs operational for as long as possible.

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. If you prefer to contract directly with a preferred contractor or manufacturer but don't have the time or in-house resources to effectively manage roofing projects, our CMS program may be just what you need. Additional details of our program are available in our CMS brochure.

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