Roof Waterproofing
Roof Waterproofing Services for Commercial Buildings in South Florida
Investing in a roof system is one of the most important decisions when it comes to your property in Florida. There are many options to choose from, including metal, asphalt, flat and many other materials. Selecting the type of roof that is best for your structure’s needs is a high priority, but what many often do no realize is the importance of also roof waterproofing.
What is Roof Waterproofing?
What is the Life Expectancy for a Roof that is Waterproofed vs a Roof that is Not?
The difference in longevity between a roof that has been waterproofed, and one that has not, literally is the best example of why adding a waterproofing membrane to a new roofing system is simply the best choice.
Roof without Waterproofing
A roof that was not waterproofed when installed will typically only have a lifespan of about five (5) to ten (10) years (the type of material used, exposure to harsh weather, etc. will have some impact on this calculation). In Florida, a roof without waterproofing is highly vulnerable to extreme weather conditions (i.e. tropical storms, hurricanes, intense humidity, excessive rainfall), as well as the consistent heat and UV exposure. These types of circumstances will frequently result in early leaks, water damage, and mold and mildew which consequently will require more maintenance and frequent repairs.
Roof with Waterproofing
The expected lifespan of a roof that was waterproofed during installation is generally between fifteen (15) and thirty (30) years (depending upon the type of roof installed and weather and environmental conditions). Roof waterproofing pays for itself over time as it provides a barrier that protects against water infiltration and makes the roof structure more durable from the UV rays (which cause early defects) and harsh weather conditions.
The Benefits of Adding Roof Waterproofing include:
- Improves the structure’s resilience
- Prevents mold and mildew from forming
- Reduces the need for repairs and maintenance throughout the life of the roof
- Reduces the possibility of leaks and water damage
What are the Best Options for Roof Waterproofing?
Roof waterproofing is available using a variety of options. A Florida licensed roofing contractor will be helpful in determining the best roof waterproofing method for your home or building.
Below are the most common roof waterproofing options in Miami:
Bituminous Waterproofing
An asphalt and tar type substance
Cementitious Waterproofing
A muck or paste most often used for concrete roofs
Green Roofs
Green roofing is natural waterproofing using plants and soil (most commonly used for commercial building)
Integral Waterproofing Additives
Liquid Waterproofing
Membrane Waterproofing
Metal Roof Waterproofing
Specialty coatings are used, as well as sealants and tapes to seal joints and seams for metal roofing
Silicone Coatings
How Long Does Roof Waterproofing Last?
As with any type of structural improvement, how well the waterproofing is applied will be a factor in determining how long waterproofing will maintain its effectiveness. Other variables will also come into play, such as the type of material used, weather conditions, and how well the roof has been maintained. Nevertheless, waterproofing will typically need to be reapplied periodically.
Below describes the average life expectancy of roof waterproofing based on the type of waterproofing materials used:
Membrane Systems are the longest lasting and will usually not need a reapplication before fifteen (15) to thirty (30) years.
Bituminous Products are expected to need a reapplication approximately every ten (10) to twenty (20) years
Cementitious and Liquid Coatings typically require a new application every five (5) years to ten (10) years.
Regular roof inspections and proper maintenance throughout the life of the roof will help to keep waterproofing and the overall roof system in the best condition possible. Homeowners and commercial building owners who have their roof inspected annually and after storms (or any environmental circumstances that may have negatively impacted your roof) will always be advantageous.
Any signs of leaks, water damage, cracks, or blisters detected within the waterproofing layer will need to be addressed immediately. Should mold and mildew be identified, this is also an indication that repairs and/or maintenance are necessary. Establishing a roof maintenance contract with a local Miami roofer will help to protect your investment and reduce costs in the long run.
