How Long Do Certain Commercial Roofing
Materials Last In Lebanon, NH?

It’s Good To Know Before Making
A Roof Replacement Decision

Smart business owners and managers know that making any important decision – including about commercial roofing in Lebanon, NH – requires a lot of data.

The lifespan of the materials that make up a specific type of commercial roof should play a part in decision-making. The longevity of the primary material will determine how often the roof:

• requires maintenance
• may need repairs
• needs to be replaced

The frequency of these events will impact business operations and financial demands. If a roof requires extensive repairs after a harsh winter in Lebanon, NH, those are sunk costs. A roof requiring more repairs may not last as many years as one with lower maintenance needs.

At Jancewicz & Son, we strive to educate other entrepreneurs and business owners in our New England communities. We want to make life easier for others, especially since our company has been around since 1933.

Rubber Flat Roofing Materials

The two most popular types of rubber or single-ply flat roofing are EPDM and TPO. At Jancewicz & Son, we are experienced with both.

Many businesses use rubber membrane roofing for their flat or low-slope commercial roofs. This type of roofing is also referred to as single-ply, with EPDM (ethylene propylene diene monomer) being the most common. This material is flexible, highly durable, and not affected by water damage or UV radiation. It’s easy to remove snow and to repair.

While a flat roof can’t blow off, it can accumulate water and leak, although this is rare. When installed by an expert roofer and properly maintained, an EPDM commercial roof can last up to 50 years. It is energy-efficient, solar panel compatible, and recyclable. It is also the least expensive of the commercial roofing options.

TPO (thermoplastic polyolefin) is a newer single-ply membrane roofing system option that is believed to last between 20 and 30 years. This commercial roof is made of thermoplastic material, usually white, which reflects sunlight and helps reduce air conditioning bills.

Although it’s a bit more expensive than EPDM, it’s growing in popularity. It’s durable and very energy-efficient. As time goes on, we’ll know more about how well it really compares to EPDM.

Other less commonly used commercial roofing systems in this category include: Built-Up Roofing (BUR), Modified Bitumen, Spray Coating, and PVC. We are skilled in repairing and installing these other systems. In terms of longevity, all of these options can last 20 to 30 years, but PVC (Polyvinyl Chloride) can last more than 30 years.

Metal Roofing Materials

Last but not least, there are metal roofing materials. Commercial metal roofs can last between 40 and 70 years, making them the clear winner in terms of roofing materials. Metal roofing can be used on both flat and sloped roofs. They require very little maintenance, are fire-resistant, and can withstand New England winters.

Standing seam metal roofs are popular for sloped and low-slope commercial roofs. Like all metal roofs, snow and other debris tend to slide off. Standing seam metal roofs are nearly maintenance-free due to their concealed fasteners, which are never exposed to the elements. They are also compatible with solar panels.

Standing seam metal roofs are very durable because their panels can be fabricated using galvanized metal, copper, and Galvalume Sheet. Galvalume Sheet is a cold-rolled sheet steel with a coating of aluminum-zinc alloy. These materials are very long-lasting. We have a reputation for being the leading installer of standing seam metal roofs.

Metal shingle roofs are very strong because of the perfectly engineered combination of carbon steel, aluminum, zinc, and multi-layered coatings. They are very low maintenance because they are installed with our unique four-way locking system, which gets tighter as the wind increases. Metal shingles don’t break or rot.

At Jancewicz & Son, we are a certified installer for an outstanding metal shingle manufacturer, Englert, Inc. This company offers a non-prorated, transferable lifetime warranty.

How The Lifespan Of Roofing Materials Plays A Role

We are a leading commercial roofing company in Lebanon, NH, and New England, recognized for our integrity. This means we will tell you if you only need repair work and not recommend a roof replacement until necessary. If you do need a roof replacement, it’s important to think about your values and how flexible your business is.

If you are concerned about sustainability, then having a commercial roof with solar panels may be more important than other factors, such as longevity. Or, if your business could never survive a lengthy shutdown, then choosing a commercial roof made of the strongest and most fire-resistant materials is critical.
