What we do

Work for every part
of your exterior.

From a roof replacement to the details around your windows and eaves, GLZ handles the work that protects and finishes your home.

01 / ROOFING

Roofing

Roof replacements and installations built around your home's needs. We assess the condition of the roof, explain the scope, and complete the work with attention to the details around edges, vents, and penetrations.

02 / WINDOWS

Windows

Window replacement and installation that improves the look and function of your home. We focus on proper fit, clean finishing, and the surrounding exterior details.

03 / FRAMING

Framing

Framing work for exterior improvements and repairs. We address the underlying structure when a project needs more than a surface-level fix.

04 / SIDING

Siding

Siding installation, replacement, and repairs, including fascia and soffit work, to refresh and protect your home's exterior and roofline.

05 / GUTTERS

Gutters

Gutter installation and repairs to help direct rainwater away from the roofline and home. We can include gutters as part of a larger exterior project.

06 / REPAIRS

Repairs

Targeted roof and exterior repairs, from damaged shingles and flashing to problem areas around walls, trim, and other exterior components. We look at the cause before recommending the fix.

07 / OUTDOOR STRUCTURES

Outdoor Structures

Custom-built outdoor structures designed to add function, shade, and character to your home.

1,000+

Installations completed by our crews across Houston and the Greater Houston area.

Financing available

Ask us about options for your roofing, window, or exterior project. Subject to approval.
