Re-Roofing Services

Is your roof nearing the end of its life? Whether you notice signs of wear in your commercial roof or know it is nearing the end of its warranty, you might be wondering if it’s time for a replacement. If your roof is in good condition, you have the option to re-roof the existing roof rather than tear it off and install a new one. If your roof uses shingles or a protective industrial membrane, you can add a second layer of the material directly on top of the existing roof. You’ll add years to your roof’s life expectancy for a fraction of the cost of a full replacement.

Re-roofing is an alternative to completely removing and replacing a roof. When re-roofing is employed, a second layer of shingles is placed on top of an existing roof. While not always possible, re-roofing can help you save on replacement costs. Since the existing roof does not need to be torn off, there’s less labor and time involved. The process is also called recovering since the existing roof is covered with an additional layer.

Another critical benefit of re-roofing is significant savings on materials. To understand just how much you save, consider how many layers comprise your roof.

Flat and low-pitched roofs usually consist of three layers.

Weatherproofing: All roofs need at least one layer of weatherproofing to keep out moisture. Areas in colder regions might also need an ice-protective barrier.

Reinforcement: Another layer adds durability, puncture-resistance and structural stability to the roof.

Surfacing: A top layer protects the two bottom layers from the weather and sun. The surfacing can add additional benefits, such as fireproofing or energy-efficient solar reflective coatings.

A commercial pitched roof typically consists of four layers.

Decking: Also called sheathing, this bottom layer of the roof is usually a panel of plywood that acts as a foundation for the roof.

Ice and water barrier: Self-sealing and waterproof, the ice and water membrane protects your building from water penetration and ice build-up.

Underlayment: A uniform layer of felt protects against water infiltration under the shingles, and allows the shingles to lay flatter.

Shingles: Asphalt shingles, metal panels or wood shakes are the recognizable outer layer of your roof. They provide architectural aesthetics as well as protection. Asphalt shingles will also have a fifth layer, called a ridge cap. The ridge cap is an extra-long shingle that fits over the vertices of the roof.
