Roof Types
From consulting and strategy development to implementation and support, our comprehensive services can help your business thrive.
Metal Roofing Types
Metal roofs are known for their extreme longevity, often lasting 40 to 70 years, and their ability to reflect heat to lower energy bills.
Steel Roofing: The most common metal type, steel is strong, affordable, and comes in various finishes to resist rust. It’s a great all-around performer for most climates.
Aluminum Roofing: Highly recommended for coastal areas because it does not corrode or rust when exposed to salt spray. It is lightweight but softer than steel, meaning it may dent more easily during hail.
Standing Seam Metal: This premium style features vertical panels with concealed fasteners, which significantly reduces the risk of leaks. It has a sleek, modern look and handles thermal expansion well.
Corrugated Metal: Often the most affordable metal option, these panels have a wavy or ribbed pattern. They use exposed fasteners, which require more long-term maintenance to ensure they stay watertight.
Stone-Coated Metal: These are steel panels coated with stone granules to look exactly like traditional asphalt shingles, clay tiles, or wood shakes. You get the aesthetic of shingles with the 50-year durability of metal.


RPI Rubber Roofing Systems
RPI offers three main product lines under their rubber roofing category:
Royal Edge EPDM: This is their flagship synthetic rubber membrane. It is highly flexible and remains stable in extremely low tempatures it makes it reliable in New Hampshire winters.
Non-Reinforced: A clean, talc-free membrane designed for fully adhered systems.
Reinforced: Features an internal polyester scrim for added strength and puncture resistance, ideal for mechanically attached or ballasted systems.
Re-Flex EPDM: A version designed with reflective properties to improve energy efficiency by reducing heat absorption.
Re-Flex TPO: A white, reflective thermoplastic polyolefin membrane geared toward energy-efficient, low-slope commercial needs.
Shingle Roofing Types
Shingles are the most popular roofing choice in North America because they are affordable and versatile.
Asphalt Shingles (Traditional 3-Tab): The most budget-friendly option, these are flat, thin shingles with a uniform look. They typically last 15 to 20 years and are the easiest to install and repair.
Architectural (Dimensional) Shingles: A step up from 3-tab, these have multiple layers for a textured, 3D look that mimics wood shakes. They are more durable, have better wind resistance, and can last 25 to 30 years.
Wood Shingles & Shakes: Usually made from cedar or redwood, these offer a high-end, rustic aesthetic and natural insulation. Shingles are machine-cut for a uniform look, while shakes are hand-split for a rougher texture. They require significant maintenance to prevent rot and are a higher fire risk.
Slate Shingles: Made of natural stone, slate is the "forever" shingle, often lasting 50 to 100 years. It is fire-resistant and incredibly durable but very heavy and among the most expensive materials to install.
