Best Roof Replacement in Denver, CO

The GAF Golden Pledge is GAF's highest-tier warranty, covering both materials and labor for up to 25 years and backed by GAF's corporate guarantee rather than just the installer's. It requires installation by a GAF Master Elite contractor (the top 3 percent of GAF-certified contractors), use of a qualifying GAF roofing system, and registration with GAF within 60 days of installation. The warranty is transferable once if you sell the home, which adds documented value at resale. Apex is a GAF Master Elite contractor and includes Golden Pledge registration as standard on all qualifying installs.

We assess the existing ventilation ratio against the IRC requirement of 1:150 (1 square foot of net free area per 150 square feet of attic floor) and calculate whether the current intake and exhaust balance meets that standard. On most replacements, we install continuous ridge vent along the full ridgeline paired with soffit intake vents — a balanced exhaust-intake system that moves the maximum volume of air through the attic. We do not mix power ventilators with ridge vent on the same attic, as the combination defeats the passive system. All ventilation components are manufacturer-matched to the shingle system for warranty compliance.

All major architectural shingles are now marketed with 'limited lifetime' warranties, but the term is prorated — meaning the coverage decreases over time. In practice, the warranty value in years 1 to 10 is strong; in years 20 to 30, the prorated value covers only a fraction of replacement cost. The meaningful comparison is the non-prorated period, the wind speed rating, and whether a contractor's labor warranty accompanies the material warranty. Apex's 5-year labor warranty runs alongside the manufacturer's material coverage, ensuring the most failure-prone early period is fully covered.

We inspect every decking panel during tear-off, probing soft spots and checking for delamination. Any OSB panel with more than 1 inch of deflection between rafters, visible delamination, or soft texture from water absorption is replaced before the new roof system goes down. We note all replaced panels on the job sheet and photograph them with measurements. Decking replacement is charged by the sheet as a separate line item in the estimate, not bundled into a flat rate that obscures what you are actually paying for.

Proper chimney flashing uses a three-component system: base flashing that covers the joint at the roof plane, step flashing that integrates each shingle course with the chimney side wall, and counter-flashing that is cut into a reglet in the mortar joint and lapped over the step flashing. This system allows differential movement between the chimney and the roof structure without breaking the seal. The common inferior method — a single piece of metal bent at 90 degrees and sealed with roofing cement — does not accommodate movement and fails in 5 to 8 years. Apex uses the three-component method on every chimney.

Class 4 impact resistance (UL 2218 standard) is the highest rating and is strongly recommended in Dallas, Denver, and other frequent-hail markets. Class 4 shingles withstand direct impact from 2-inch steel balls dropped from 20 feet — simulating golf-ball-sized hail — without fracturing. Most major insurance carriers offer a 20 to 30 percent premium discount for Class 4 roofs, which typically recovers the material cost premium within 3 to 5 years. We provide the manufacturer's certification document for insurance submission after installation.

Not required, but we recommend someone be available for the start-of-day walkthrough and end-of-day inspection.

Choosing standard architectural shingles, scheduling in the off-season (late fall or early spring), and getting multiple quotes can all reduce costs.

We can discuss staged payment arrangements for larger projects — ask when you book and we'll outline what's available.

A new roof adds resale value, eliminates recurring repair costs, and improves energy efficiency — most homeowners find it worthwhile within a few years.
