Professional Roof Installation

Professional Roof Installation in Colorado

A new roof is only as good as the crew that installs it. At Sonners Contracting, every installation is treated as a complete system — not just shingles, but the underlayment, ventilation, flashing, and protective layers that work together to keep your home dry and energy-efficient for decades. Since 2013 we have installed more than 1,000 roofs across Northern Colorado and the Denver Metro, and we bring that same attention to detail to new construction, replacements, and additions.

What a Complete Roofing System Includes

When we install your roof, we install every component to manufacturer specifications:

• Decking inspection — we verify the roof deck is sound and replace any damaged or rotted sheathing before anything goes on top.
• Synthetic underlayment — a durable moisture barrier that outperforms traditional felt.
• Ice-and-water shield — extra protection at eaves, valleys, and penetrations where Colorado ice dams and wind-driven moisture cause leaks.
• Balanced attic ventilation — intake and exhaust that prevent heat and moisture buildup, extend shingle life, and lower energy bills.
• Flashing and drip edge — correctly installed metal that seals the most leak-prone areas of your roof.
• Premium shingles — architectural or impact-resistant shingles from GAF, Owens Corning, and CertainTeed.

Built for Colorado's Climate

High-altitude UV, dramatic freeze-thaw cycles, heavy snow, and frequent hail make Colorado one of the toughest places in the country to roof a home. We install systems engineered for exactly these conditions, with proper ventilation and ice protection that many cut-rate installers skip. The result is a roof that performs the way it should — and keeps its manufacturer warranty valid.

Installation vs. Replacement

If your home already has a roof at the end of its life, you likely want a full roof replacement, which includes tearing off the old materials first. New installation applies to new construction, additions, or structures that have never been roofed. Not sure which you need? Our free inspection will tell you, and we will recommend the most cost-effective path — never the most expensive one.
