Roof Replacement: What to Expect & How to Prepare
When it’s time to replace your roof, understanding the full scope of the project helps ensure a smooth experience. At Reformation General Contracting, we believe transparency, education, and craftsmanship are the foundation of every great roofing project. This guide walks you through everything you need to know—from materials to prep work—so you feel confident every step of the way.
Roofing Process Breakdown
-
Understanding what makes up your roof helps you ask the right questions:
Decking – The base layer, usually plywood or OSB.
Underlayment – A water-resistant barrier installed between the decking and shingles.
Shingles or Roofing Material – The outermost protective and aesthetic layer.
Flashing – Seals transitions and penetrations.
Ventilation – Allows air to flow in and out of the attic.
Gutters & Downspouts – Manage water runoff away from your home’s foundation.
-
Every roof has different needs based on style, budget, climate, and longevity goals. Here are some of the most popular options:
Asphalt Shingles – Affordable, durable, and available in a range of colors and styles. Most common in residential roofing.
Architectural (Dimensional) Shingles – Thicker and more textured than standard asphalt; longer lifespan and better aesthetics.
Metal Roofing – Long-lasting, energy-efficient, and modern. Available in panels or shingles, with finishes ranging from matte to standing seam.
Slate & Synthetic Slate – Premium look and performance with unmatched durability. Heavier and more costly but ideal for luxury homes.
Wood Shake – Natural beauty with rustic appeal. Requires more maintenance and isn’t ideal in fire-prone areas.
Flat Roofing Systems (for low-slope sections) – TPO, EPDM, and modified bitumen options for proper drainage and waterproofing.
-
The key to a long-lasting roof isn’t just the shingles—it’s the system beneath them:
Ice & Water Shield – A self-sealing underlayment installed at eaves, valleys, and vulnerable areas to prevent ice dam and wind-driven water damage.
Synthetic Underlayment – Replaces traditional felt with a durable, tear-resistant base that adds an extra layer of protection.
Drip Edge – Installed along roof edges to direct water into gutters and protect decking from rot.
Starter Shingles – Prevent blow-offs at the eaves and rakes while enhancing waterproofing.
Flashing – Metal detailing around chimneys, skylights, valleys, and roof-to-wall connections to prevent water intrusion.
-
Proper ventilation extends your roof’s life and improves energy efficiency:
Ridge Vents – Installed along the peak of the roof to release hot air.
Soffit Vents – Located under the eaves, drawing in cool air from outside.
Box Vents or Gable Vents – Traditional options for targeted airflow.
Powered Attic Fans – For homes with specific ventilation needs or high attic heat.
A balanced system (intake + exhaust) keeps your attic dry and your home comfortable year-round.
