PELLA DOORS
Premium entry, patio, and storm doors — engineered for Colorado's climate extremes, backed by a Pella Certified installation.

Pella Doors in Denver, Colorado
Your entry door faces Colorado's full range of extremes — sub-zero winters, intense UV, hail, and dramatic temperature swings that can warp, crack, and seal-fail cheaper products within a few years. Pella doors are engineered specifically to handle these demands, with fiberglass frames that expand and contract minimally across temperature ranges, keeping seals tight and drafts out year-round.
As a Pella Certified Contractor, The Roofing & Siding Company installs the full line of Pella entry, patio, and storm doors to manufacturer specifications — ensuring your warranty is fully backed and your door performs at its peak from day one.

Why Pella Doors for Colorado Homes
Colorado's climate creates specific demands that Pella is built to meet:
- Minimal Thermal Expansion: Pella fiberglass frames expand and contract significantly less than wood or vinyl across temperature extremes — critical for maintaining weathertight seals through Colorado's dramatic seasonal swings.
- ENERGY STAR Certified: Many Pella door lines carry ENERGY STAR Most Efficient ratings, with some of the lowest U-factors in the industry — reducing heating and cooling costs year-round.
- UV Resistance: Colorado's high-altitude UV is significantly more intense than at sea level. Pella's finishes and glass packages are engineered to resist fading and deterioration under prolonged sun exposure.
- Security: Multi-point locking systems engage at multiple points along the door frame for superior resistance to forced entry — available across Pella's entry door lineup.
- Noise Reduction: Pella's tight seals and glass packages provide meaningful sound dampening — particularly valuable for homes near busy roads or in urban neighborhoods.
Our Door Installation Process
A door is only as good as its installation. Our certified process ensures perfect performance:
- In-Home Consultation: We assess your current door, discuss your priorities — energy efficiency, security, style — and help you select the right Pella door for your home.
- Style & Finish Selection: Choose from Pella's extensive options for panel design, glass, color or stain, and hardware to create your ideal entry.
- Rough Opening Preparation: We ensure the door opening is square, plumb, and properly sized — the foundation of a draft-free, long-lasting installation.
- Professional Installation: Your new door is carefully shimmed, leveled, and secured per Pella specifications, with proper insulation around the entire frame.
- Weatherstripping & Hardware: All weatherstripping is adjusted for a tight seal, and hardware is installed and tested for smooth, secure operation.
- Final Inspection: We test the door for smooth operation, proper locking, weather sealing, and overall appearance before completing the project.
“Jack and his team replaced the siding on half of our house, including our chimney. Our old siding was damaged and rotting. They replaced it with James Hardie siding and painted it all to match. It looks great! They were fast and professional. Jack is a real pro and it shows. Would hire again!”
