Windows

Windows are where comfort, light, and efficiency meet the outside world. When they fail, the whole house feels it: drafts in the winter, condensation on the glass, rising utility bills, and rooms that never quite reach the thermostat setting. Roof Technologies is an authorized dealer for Andersen, Pella, and ProVia, and we carry the major vinyl and fiberglass lines through our distributor relationships with ABC Supply and Lansing Building Products. That gives us a full price-and-quality range under one roof — premium wood-composite at the top, quality vinyl at the middle, and budget-friendly vinyl that still performs at the entry level.

Window Brands We Sell & Install

We fit the window to the house, the climate, and the budget — not the other way around. Short summary of our lineup and where each brand fits best:

• Andersen: The premium wood-composite standard. 400 Series and E-Series lines feature real-wood interiors with Fibrex or aluminum-clad exteriors for essentially zero maintenance outside. Strongest choice for higher-end remodels, historic neighborhoods, and projects where interior appearance matters.
• Pella: Full lineup from entry-level vinyl (Pella 150 Series) through mid-grade fiberglass (Impervia) to premium wood and wood-composite (Lifestyle, Architect, Reserve). Excellent fit for whole-house replacements where matching multiple room priorities is important.
• ProVia: ProVia’s Endure, Aeris, and Aspect window lines combine premium fiberglass and vinyl construction with dealer-exclusive customization. Particularly strong on entry-door / window system coordination when we’re also replacing siding or doing whole-exterior work.
• Milgard: Strong vinyl and fiberglass lines (Tuscany, Trinsic, Ultra fiberglass), well-suited to Colorado’s temperature swings and UV exposure. Lifetime warranty including glass seal failure is best-in-category.
• MI Windows & Doors: Broad vinyl lineup (MI 1620, 1650, 8500, 9950 series) from entry-level rental-grade through mid-premium. Strong value-to-spec ratio when project budget is the driver.
• PlyGem: The Pro Series and MIRA lines cover vinyl and aluminum-clad vinyl respectively — a frequent fit on new construction, large tract renovations, and multi-family where a consistent spec across many openings matters.
• Simonton: StormBreaker Plus (impact-rated) and the Reflections and ProFinish lines serve the value-vinyl segment with strong warranty backing.
• Silver Line (Andersen): Andersen’s value vinyl sub-brand. A strong option when the rest of the house will get premium Andersen wood-composite but a guest room, basement, or garage window needs a budget-matched replacement from the same manufacturer family.
• Atrium, CGI, and other distributor brands: Available through our ABC Supply and Lansing Building Products relationships when a specific brand is spec’d (builder preference, HOA match, or insurance-claim like-kind). Ask and we’ll tell you honestly whether we’d steer you there or toward a line we know better.

Why Replacement Windows Are Worth It

A single-pane window from the 1970s loses heat roughly ten times faster than the wall around it. Even a 20-year-old double-pane unit has likely lost its seal, its inert gas fill, and much of its original performance. Replacing aging windows is one of the highest-impact upgrades a homeowner can make for comfort and energy use.

• Energy Efficiency: Modern double-pane and triple-pane units use low-E coatings and argon gas fills to reflect heat back where it belongs. In summer, heat stays outside. In winter, it stays in.
• NFRC Performance Ratings: Every window we install carries a National Fenestration Rating Council label. We'll walk you through U-factor, Solar Heat Gain Coefficient, Visible Transmittance, and Air Leakage so you understand exactly what you're getting.
• Noise Reduction: Thicker glass and sealed insulating glass units cut outside noise dramatically, which matters on busy streets or near highways.
• UV Protection: Low-E coatings block much of the UV radiation that fades flooring, furniture, and artwork over time, especially at Colorado elevation.
• Resale Value: Window replacement consistently ranks among the top home improvement projects for return on investment.

Window Styles We Install

Every home is different, and the right style depends on the room, the view, the ventilation you need, and how the window will look from outside. We'll help you choose configurations that fit both function and architecture.

• Double-Hung: The American classic. Both sashes slide, both tilt in for easy cleaning from inside. A safe choice for most rooms.
• Casement: Hinged on the side and cranked outward for full, unobstructed airflow. Excellent for kitchens and hard-to-reach spots over counters.
• Sliding: Horizontal sliders are ideal for wide openings in basements, bedrooms, and walls where a crank-out casement would hit a walkway.
• Bay and Bow: Projecting window combinations that add floor space, create a reading nook, and dramatically improve curb appeal on living rooms and dining rooms.
• Picture and Specialty: Fixed-pane windows for uninterrupted views, plus custom geometric shapes like half-rounds, octagons, and trapezoids to match original architecture.
• Awning: Hinged at the top and pushed outward from the bottom. Great for ventilation during light rain and often paired above or below picture windows.

Frame Materials: Vinyl, Fiberglass, and Wood Composite

The frame matters as much as the glass. Each material has a role, and we'll be straight with you about tradeoffs.

• Vinyl: The most popular choice for good reason. Low maintenance, strong thermal performance, and an attractive price point. Modern welded corners have eliminated the leak points older vinyl windows were known for.
• Fiberglass: Dimensionally stable, meaning it doesn't expand and contract with temperature swings the way vinyl does. That makes it a standout in Colorado, where a 50-degree daily swing isn't unusual.
• Wood and Wood Composite: Real wood interiors for a warm, traditional look, wrapped in a low-maintenance aluminum or fiberglass exterior. This is where Andersen and Pella truly shine on higher-end remodels.

Our Installation Process

Window failure almost always starts with bad installation, not bad product. Our crews follow a documented process to make sure your windows perform the way the manufacturer intended.

• In-Home Measurement: We measure each opening in three places, inspect the existing frame, and check sill and jamb condition before ordering.
• Careful Removal: Old units come out without damage to interior trim, drywall, or siding wherever possible.
• Opening Prep: Rotted wood is replaced, openings are squared, flashing is inspected, and sill pans are installed where conditions warrant.
• Proper Shimming and Sealing: Windows are plumbed, leveled, and squared, then sealed with low-expansion foam so frames don't bow under pressure.
• Exterior Flashing and Trim: Flashing tape, caulking, and trim are installed to shed water correctly and tie into existing siding or stucco.
• Interior Trim and Cleanup: We reinstall or replace interior casing and leave every room cleaner than we found it.

Signs It's Time for Replacement Windows

Windows rarely fail all at once. They get tired slowly, and most homeowners don't realize how much comfort they're losing. If any of these sound familiar, an inspection is worth your time.

• You can feel a draft when you hold your hand near the sash or frame.
• Condensation, fog, or moisture appears between the panes of glass, which means the seal has failed and the gas fill is gone.
• Windows are painted shut, stick when you try to open them, or won't stay open without a prop.
• Your heating or cooling bills have climbed without a clear cause.
• You hear outside noise you shouldn't, or rooms facing the sun are uncomfortably hot in the afternoon.
• Wood frames show rot, soft spots, or peeling paint, especially at the sill.
• Locks don't engage cleanly, which is both an energy issue and a security one.

After the Storm: Windows and Insurance Claims

Colorado, Kansas, Missouri, Nebraska, and Wyoming see some of the most intense hail in the country, and windows take a beating alongside roofs. Shattered panes, cracked frames, bent screens, and damaged grids are all commonly covered under homeowner policies. Because we typically handle the roof claim alongside the windows, we can document window damage during the same inspection and include it in the supplement request, so nothing falls through the cracks between trades.

Warranty Coverage

Andersen, Pella, ProVia, Milgard, MI, PlyGem, Simonton, and Silver Line all back their products with manufacturer warranties that cover glass, frames, hardware, and factory-applied finishes — the specifics differ by brand and line, and we’ll walk you through the exact warranty package for whichever window you choose before you sign. Roof Technologies stands behind our workmanship separately, so the install is covered by us and the product is covered by the manufacturer. We keep your registration paperwork on file and help coordinate any future service call with the factory if one is ever needed.
