Asphalt shingles

A high-performance, budget-friendly option, asphalt shingles are efficient and long-lasting.

Cedar roofing

Cedar roofs – one of the most beautiful varieties of roofing – will give your home a timeless visual appeal and increase the value of your home. 

Slate roofing

As one of the oldest roofing materials in history, slate is widely considered one of the most attractive, highest quality, long-lasting roofing materials available.

Composite Roofing

An alternative to cedar and slate, composite (or synthetic) tiles and shingles are high-performance materials designed to resemble cedar shakes, slate, and clay barrel tiles.

Metal Roofing

Extremely durable and long-lasting, metal roofing is a premium, low-maintenance, energy efficient, and eco-friendly material.

Flat Roofing

The workmanship behind flat roof installation is different from sloped roofing, as it requires attention to proper sealing, finishing, and drainage.

Aluminum Work

A well-maintained exterior system requires properly installed soffit, fascia, and eavestroughs to keep roofs dry and ventilated, and to protect the structural integrity of the house.


To protect a house from severe weather and moisture, Trillium Construction Group maintains, inspects, and installs siding in a variety of materials: vinyl, composite wood, composite cement, metal, and cedar.


Skylights brighten up interiors with natural light, which helps save heating costs as well as increases the value of your house.
