When you’re investing in a new roof, you don’t just want protection — you want performance, beauty, and peace of mind. That’s why more homeowners across Connecticut are choosing GAF Timberline HDZ Shingles — the #1 best-selling roof in America.

At All Site Builders, we’ve installed thousands of square feet of Timberline HDZ across Cheshire, Wallingford, Southington, Meriden, New Haven, Waterbury, and beyond. As a GAF Certified Contractor, we know these shingles aren’t just popular — they’re built to handle everything New England weather throws at them.
Let’s break down why this is the smartest choice for your home.

A Roof That Elevates Your Home’s Curb Appeal
