HRTI is a full exterior home renovation source. We handle it all from the top down; roofing, gutters, windows, accordion doors, siding, painting, and more. As a residential roofing contractor our services span installation of formed resin roofs made to look like cedar shake to concrete tile to conventional architectural asphalt shingle roofs. Our professional roofing installers have over 50 combined years in the industry and are licensed and insured. We use products from manufacturers such as CertainTeed, Boral, Cedur, Davinci and others.

HRTI works with and installs replacement windows from almost any manufacturer requested including Pella, Sierra Pacific, Simonton, Sunrise, and Andersen. We prefer these company’s windows for their Energy Star rating, low-E glass coatings and energy efficiency. Additionally, many of these windows can be cleaned from the inside! Traditional window styles and custom windows are available from many manufacturers.

HRTI has worked with many substrates in siding homes including stucco, decorative real wood, porcelain tile, engineered wood with companies such as LP Smartside, and fiber cement and “panel and channel” from companies such as James Hardie. We believe strongly in both companies pre-painted offerings such as DiamondKote and Color Plus. Whether renovating due to recent hail and storm damage or it is just time to upgrade your aesthetic, HRTI is the siding contractor to handle your project.
