Critically important is to protect
the investment through proper maintenance. It is natural to get the most value
out of what we purchase. Large investment like a roof needs surety that you
will get the longest possible life out of your roof system.
The environmental considerations of a roof tear-off, roof coatings and roof
restoration systems are being common option. Cool roof coatings reduce energy bills by
decreasing air
conditioning needs and can help extend the life of roof systems. It is important to assess the current state of your roof. An
expert knowing when to repair or when to replace a roof is a critical decision
that requires knowledge. To help identify roof damage and leaks, which are most
often found in flashings and roof penetrations - address these critical areas
prior to applying any roof coating. Core cuts and non-destructive testing
provide key information in determining the condition of your roof. Also, wet
insulation on a roof will need to be removed and replaced before the roof can
be restored. An infrared scan can identify locations of wet insulation and
typically, if more than 30 percent of the roof's insulation is wet, a complete
tear-off is recommended.
Selecting the Right Roof Coating
Some important roof conditions to consider when selecting a restoration coating
include:
· Current condition of the roof
· Location
· Slope
· Ponding water
· Chemical exposure
· High heat exposure
· UV exposure
Subjecting a roof or restoration coating,
all of these conditions will greatly affect its performance and life
expectancy. It is important to consider the features and benefits and its
drawbacks of each coating type.
Acrylic Roof Coatings
In the roofing market very common are Acrylic coatings, typically water-based
products and are cost effective. They are easy to use and environmentally friendly
most often used for reflectivity, and they are designed to cool the roof down,
acrylic coatings help reduce cooling costs at a more economical value,
Polyurethane coatings provide a highly durable surface that protects the roofing system from a wide variety of conditions, have higher tensile strength when compared to most other coatings, allowing the coating to resist expansion and contraction of the roof system.
Silicone Roof Coatings
Silicone coatings have been in the industry for a long time and very well suited for areas with extreme temperature ranges and where UV exposure is more frequent,not the ideal coating for areas of high traffic.
Make sure that the coating is designed for the conditions of your particular roof. Each of these coatings has its own strengths and specific advantages that make it suitable for certain roof conditions.
