New construction roofing and replacement roofing share most technical steps but differ in 3 key ways.
New construction involves installing roofing directly onto new decking without a tear-off phase. Material selection is fully open, timelines align with builder schedules, and all ventilation systems are installed from scratch.
Replacement roofing requires tear-off of existing layers, inspection and repair of concealed deck damage, and matching new material to any existing penetrations or features. Hidden damage discovered during tear-off, including rotted decking or failed ice and water shield, is resolved before new material is installed.
Allstate Roofing manages both project types and coordinates directly with builders, general contractors, and homeowners throughout Bangor, ME.
The tear-off phase takes 1 to 2 days on most residential roofs and involves 4 steps.
Allstate Roofing performs complete property cleanup including nail sweeping with magnetic rollers on all surrounding areas before leaving the job site.
Allstate Roofing installs all major roofing materials available for residential and commercial replacement projects in Bangor, ME.
| Material | Lifespan | Best Application |
|---|---|---|
| Asphalt Shingles (Architectural) | 25 to 40 years | Budget-conscious residential |
| Impact-Resistant Asphalt (Class 4) | 30 to 50 years | Storm-prone areas |
| Standing Seam Metal | 40 to 70 years | Premium residential, commercial |
| Clay or Concrete Tile | 50+ years | Mediterranean, Spanish styles |
| Natural Slate | 75 to 100 years | Historic, luxury residential |
| Synthetic Composite | 40 to 50 years | HOA communities, budget premium |
| TPO / EPDM / PVC | 20 to 30 years | Flat and low-slope roofs |
5 primary factors determine the final cost of a roof replacement.
Allstate Roofing provides itemized, written estimates so every line-item cost is transparent before work begins.
Most residential roof replacements take 1 to 3 days. Timeline is determined by 3 variables.
Commercial and multi-building projects are scheduled in phases to minimize operational disruption.
Every Allstate Roofing replacement project includes 2 distinct warranty types.
Manufacturer warranty covers material defects and varies by product. Architectural asphalt shingles carry 25 to 30-year warranties. Premium impact-resistant and designer shingles carry limited lifetime warranties. Metal roofing systems typically include 40-year paint warranties and 40+ year structural warranties.
Workmanship warranty covers Allstate Roofing's labor and installation quality. Workmanship defects are corrected at no charge within the warranty period.
Allstate Roofing registers manufacturer warranties on behalf of every customer to ensure coverage is active from day one.
Find quick answers to the most commonly asked questions.
Replacement is recommended when 25% or more of the roof surface is damaged, the existing roof exceeds 80% of its expected lifespan, or structural decking is compromised. Allstate Roofing provides a free inspection and honest assessment of repair versus replacement for every customer.
Maine building code allows up to 2 layers of asphalt shingles. A layover avoids tear-off cost but prevents deck inspection and can void some manufacturer warranties. Allstate Roofing recommends full tear-off for all replacement projects.
Within 30 to 60 days of documented storm damage to protect your insurance claim timeline. Delaying can result in further damage being attributed to neglect rather than the storm event.
