Pre-Installation Preparation

Before work begins, several steps ensure the project runs smoothly:

1

Initial Inspection

A roofing professional inspects your roof, measures the area, and assesses the condition of the roof deck, flashing, and ventilation. This determines the full scope of work.

2

Written Estimate

You receive a detailed estimate covering materials, labor, timeline, and any potential additional costs. This becomes the basis for the contract.

3

Permits and Notifications

Most Denver-area municipalities require permits for roof replacement. Your roofer will pull permits and notify neighbors if work will be disruptive.

4

Material Delivery

Materials are delivered to the property a day or two before installation. The crew plans where materials will be stored to minimize damage to your property.

Tear-Off and Deck Inspection

On the morning of installation, the crew begins by removing the old roof:

Deck Inspection
Decking Repair Costs

Installing the New Roof

With the deck prepared, installation begins:

1

Underlayment

A water-resistant underlayment is rolled out and fastened to the deck. This provides an extra layer of protection against water intrusion.

2

Flashing

New flashing is installed around chimneys, walls, vents, and valleys. This is critical for preventing leaks at these vulnerable areas.

3

Shingle Installation

Shingles are installed starting at the eaves and working up to the ridge. Each row is carefully aligned and fastened according to manufacturer specifications.

4

Ventilation

Ridge vents, soffit vents, or power vents are installed or upgraded to ensure proper attic ventilation.

5

Ridge Cap

The final layer of shingles (ridge cap) is installed along the peak of the roof. This is a critical weather protection point.

Cleanup and Final Inspection

The final steps ensure your property is left clean and the work is done right:

Frequently Asked Questions

How long does a roof replacement take?

Most residential roof replacements in Denver are completed in 1-3 days, depending on roof size, complexity, and weather. Metal roofs may take 2-5 days. We provide a detailed timeline during the estimate phase.

Can I stay home during roof replacement?

Yes, you can stay home during the installation. However, there will be noise and vibration. Some homeowners prefer to be away during the tear-off phase if they work from home or have pets that are sensitive to noise.

What happens if it rains during roof replacement?

Roofing crews work quickly to minimize exposure. If rain is forecast, they may tarp the roof overnight. Temporary water protection is common if weather delays completion.

Do I need to be home during the installation?

You do not need to be home during the installation, but we recommend being available for the final walkthrough. You can reach the project coordinator at any time during the project.
