Commercial Silicone Roofing Systems

Would you love to renew your commercial roof waterproofing capabilities without the time and expense of replacing your entire roof system? A silicone restoration coating, also known as an SRM or silicone roof restoration membrane, renews your commercial roof into a low-maintenance, seamless system with unbeatable long-lasting performance…while also renewing your warranty!

A silicone restoration membrane from Shark Commercial Roofing Systems, out of Los Angeles, California, provides an economic, environmentally friendly, high-performance, alternative to roof replacement. If your existing roof is in relatively good shape, but nearing the end of its warranty, Shark Commercial Roofing Systems has the answer for you.

A Brilliant Option to Re-Roofing

A silicone roof restoration is composed of an adaptable self-flashing silicone material well-suited for commercial roof revitalization. Once the existing roof is prepared, a silicone coating is sprayed/rolled on. The liquid seals all imperfections and adds a waterproof layer on your commercial roof.

Regardless of the type of roof you have, flat or sloped, you can count on an SRM system. The presence of HVAC units, vents, skylights, and drainage systems pose no difficulty. Our experienced team has decades of roofing experience to ensure a positive long-term result.

Cost Considerations

An average 20,000sf commercial building will have material and labor costs ranging from $3.50 to $8.00 per square foot. Increased material costs, gas prices, and many other variables can push the cost of an installation past (or below) the average threshold.

Other variables that affect pricing include:

  • The current cost of materials
  • Size of your roof
  • The amount of wet insulation
  • The condition of your existing roof
  • How much of a slope your roof is on
  • Access to your roof
  • Climate/weather patterns in your area
  • Length of warranty

Installation Process

The process of installing a silicone roof coating system is relatively straightforward, consisting of 5 steps:

  1. Inspection and Repairs
  2. Roof Cleaning
  3. Seam Reinforcement
  4. Silicone Application
  5. Warranty

Inspection and Repairs

Should minor repairs be necessary, these must be factored into your system cost.

If your roof is not in good condition, a silicone roof coating system may not be appropriate. In general, if your roof has less than 25% of it needing repair, it is a candidate for a coating.

Your contractor will have to remove any damaged wood decking and replace the area with new material (asphalt is repaired with asphalt and so on).

Roof Cleaning

Your contractor starts the cleaning process by thoroughly power washing the entire roof surface. It is important for all dirt and debris to be removed for good silicone adherence.

Most commonly, a power wash wand/machine, using a spinning brush, is used to clean the roof surface. The roof is then dried with a powerful air dryer. If time constraints aren’t an issue, they may let the roof dry naturally.

A less used, but much more eco-friendly option is a reclamation washing process. Using heated high-pressure water with a spinning brush the roof surface is thoroughly cleaned. An attached vacuum sucks up the water, much like an industrial shop vac. The dirty water is processed through a filtration system, then disposed of in the facility sewer system. This process is more environmentally friendly as it uses less water, collects, and filters the dirty water and does not require the use of a surface dryer.

Seam Reinforcement

After cleaning, we will need to reinforce all existing seams. This step prevents further leak development in this most vulnerable area of your roofing system. There are two common types of seam reinforcement.

  • Polyester Mesh with Coating. We install a polyester-reinforced mesh into our liquid coating and apply. We then add an additional silicone coating to seal the reinforcement.
  • Self-Adhesive Tape. A self-adhesive is applied across all seams, penetrations, and flashings. A liquid topcoat is applied over the tape. Though more expensive up front, the additional costs may be offset in time/labor.

Coating Application

Now that everything is prepared, we are into the application of the silicone coating.  The coating may be either sprayed or rolled on. As it dries, it forms a seamless, monolithic layer across the entire surface, protecting the repairs, seams, and entire roofing structure.

How many layers are applied depends on the coating manufacturer selected. Be sure to clarify with your contractor what the manufacturer specifications are.


Once the application process is completed, the system may then be inspected by a 3rd party. This is done to ensure the application meets the manufacturer’s specifications. Upon approval, the system warranty is issued.

Warranty cost is based on length and manufacturer, with most warranties offering 10-20 years of coverage.
