Roof Replacement, Siding Replacement, Window Replacement, & Gutter Installation in Longmont, CO

Project Summary

WestPro completed a full exterior renovation on this Longmont, CO home in December 2023. Our team replaced the steep-slope roof with GAF ArmorShield II Shingles in Weathered Wood and installed James Hardie Lap Siding in Arctic White with Cobblestone trim. We also added a 5-inch seamless aluminum gutter system to protect the new exterior.

The Problem

Geraldine reached out after noticing dents in her pickup truck from a recent hail event, which prompted an inspection of her Longmont home. She was concerned about the condition of her roof and exterior, so she contacted us to see if the damage warranted a full replacement rather than spot repairs.

Our inspection confirmed that the roof, installed around 2008, had sustained hail damage. The siding also showed signs of wear that required attention. Because the exterior components had been in place for over a decade, the existing materials had reached the end of their useful life and needed a complete update to restore the home's integrity.

Why It Needed Replacing

A simple repair would not have addressed the widespread age-related wear on the roof and siding. Replacing the entire system allowed us to bring the home up to current standards with fresh, matching materials instead of leaving older, vulnerable sections in place.

What We Did

We began the project by removing the old roofing materials and addressing the steep-slope installation requirements. Our team installed new GAF ArmorShield II Shingles in Weathered Wood, which are Class 4 impact-resistant to withstand future hail events. We integrated new roof vents, new drip edge along the eaves and rakes, new pipe jack flashing, new chimney flashing, and new step flashing to ensure a watertight seal. The roof work provided a durable base for the rest of the exterior updates.

For the siding and windows, we installed James Hardie Lap Siding in Arctic White with Cobblestone trim to refresh the home's appearance. The scope included replacing 9 windows and doors to improve energy efficiency and curb appeal. We finished the project by installing a 5-inch seamless aluminum gutter system in 30 degree white to manage water runoff effectively.

Project Details

This project involved a comprehensive exterior update covering a 30.3-square roof, which equates to approximately 3,033 square feet of roofing area. The siding work covered 11 square feet of wall space, and we replaced 9 window and door openings. The roof presented a steep-slope challenge that required specialized installation techniques to ensure safety and quality.

Work was coordinated across multiple trades to handle the roofing, siding, window replacement, and gutter installation in a unified effort. The project was completed in December 2023.

Materials Used

• 5" Seamless Aluminum Gutter System in 30 degree white

Price Context

This project's roof work was completed at approximately $6 per sq ft installed. This figure represents the complete installed scope for the roof portion of this home, including tear-off, trim, and labor, rather than just the cost of the shingles alone, which is why a specific home's all-in rate often runs above general market averages. Homeowners considering a similar GAF ArmorShield II Shingles project in Colorado should generally expect pricing in the range of $6.75–$8.50/sq ft installed. Pricing varies based on roof size, pitch, the number of existing shingle layers, ventilation upgrades, skylights, chimneys, decking replacement, and local building-code requirements. Colorado's Front Range is one of the most active hail markets in the country, so Class 4 impact-resistant shingles like GAF ArmorShield II are designed to take a hit and keep going, flexing on impact instead of cracking like a standard shingle.

Homeowners considering a similar James Hardie 8.25" HardiePlank Lap Siding – Primed project in Colorado should generally expect pricing in the range of $19.00–$23.00/sq ft installed. Costs for siding projects depend on the siding profile and exposure, the trim package, wall complexity, existing-siding removal requirements, sheathing repairs, and any soffit or fascia work bundled with the installation. This homeowner chose primed HardiePlank, which means the siding gets painted after installation, and field painting on a full house typically runs $8,000–$15,000 depending on the home.

Homeowners considering a similar Entry Door project in Colorado should generally expect pricing in the range of $3,000–$10,000 per door installed. The final cost for windows and doors is influenced by the window and door count, size, insert vs. full-frame installation, the glass package, and interior trim requirements. We install Pella, Waudena, and some ProVia entry doors, either standalone or bundled with siding and window projects, offering options in fiberglass, steel, or wood materials.

Homeowners considering a similar 5" Seamless Aluminum Gutters project in Colorado should generally expect pricing in the range of $13.00–$15.00/LF installed. Gutter pricing varies by total linear footage, the number of downspouts, gutter size, drainage improvements, and site access. We custom-formed these gutters on site from a continuous coil of aluminum, one piece per run with no seams, because seams are where gutters leak, so eliminating them is the whole point of seamless installation.

The Result

Finished in December 2023, this Longmont home now features a durable, impact-resistant roof and a freshly updated exterior with Arctic White siding and Cobblestone trim. The replacement of the steep-slope roof and aging siding restored the home's protective envelope and modernized its curb appeal. Projects like this are common throughout Longmont, where older homes often require full exterior updates after hail damage reveals the end of the materials' useful life.
