Problems Silicone Restoration Membranes Have

 
Silicone Restoration Membranes are becoming increasing popular, and it’s not hard to see why. They’re more cost-effective than a complete roofing tear off, provide a 10- or 15-year warranty and are environmentally friendly.

But along with those advantages, they also come with their own set of disadvantages.

Restoring, repairing or replacing your roof is an ultra-important decision that needs to be made, so any building owner interested in making this decision would be wise to learn all the facts.

Here are the most common problems the silicone restoration membrane roofing solution runs into

Slippery

 
When SRM’s get wet, they can be very slippery. For areas of high foot traffic, such as near HVAC units, a roofing contractor will add sand into the wet coating during application.

The sand provides a more stable walking area, and it also provides some strength to handle the abuse when HVAC panels and tools get placed down.

Eligibility

 
For an existing roof system to be eligible for an SRM installation, the roof needs to be in better condition than most roofs at the end of their serviceable life. Some signs of a roof in good condition include:

  • The seams of the existing membrane are relatively intact
  • The field of the roof has been properly maintained over its life
  • Less than 25% of the underlined substrate and insulation is wet (It is still cost-effective to do spot replacement of small saturated areas rather than a complete replacement.)

 
Typically, 20-30% of roofs will be ineligible due to neglect of the roof or the lack of a previous maintenance program.

Dingy

When an SRM is first installed, it’s a white/gray, shiny product of pure elegance.

Problems that Silicone Restoration Membranes have

Like your new car after a few years, the shine doesn’t last.

Some of the outside elements, such as leaves, dirt and algae tend to stick to an SRM.

Having outside elements on your SRM won’t affect the performance of the roofing solution, but it’s just a foreseen problem in having something so gleamy white.

Built-up roofs

 
Built-up roofs tend to have uneven gravel or stones on the outer most layer of the roof. When spraying down silicone, it’s hard to get a smooth surface over this rocky area.

Some roofing contractors will lay down SRM’s over built-up, some won’t.

Do these Silicone Restoration Membrane problems scare you away?

 
Those are the main SRM problems. You may have heard of others. Just remember to consider the source when someone tells you about everything that can go wrong with an SRM system.

SRM’s are somewhat of a newer roofing solution, so many building owners haven’t worked with this solution.

When considering an SRM roofing solution, it’s recommended to get advice from a roofing contractor with 40+ years of experience working with silicone.

Many of the biggest problems can be prevented by using a reliable, reputable roofing contractor.
