Pittsburgh Roofers

New Roofing Systems



Shingle roofs come in a wide variety of types, brands, designs, and colors, which makes them the most popular choice in residential roofing. Shingles are low maintenance and easy to repair should any damage from wind, hail, trees, or animals befall your roof. We are GAF certified installers but also work with CertainTeed and Owens Corning shingles regularly so we are equipped to install any shingle from any brand you choose. There are three main categories of shingles:

3-Tab Shingles

This is the oldest and most common type of shingle. They are flat tabs and generally are rated for 25-30 year life expectancy. This is the most economical shingle

Dimensional Shingles

This is a modern update to the old-fashioned 3-tab shingle. It is a multi-layer shingle that adds dimension to the roof. Dimensional shingles carry a limited lifetime warranty and are a better looking and longer lasting shingle than the 3-tab for not a lot more money. This is the type of shingle most new and roof replacements are now done with.

Designer shingles

These shingles come in various designs to fit certain architectural looks as well as mimic other roofing products at a cheaper cost. There are shingles designed to look like slate, shake, and tile. Each has their own distinct look.
