Does Roof Coating Stop Leaks?
Flat roofs are exceptionally popular for commercial properties for a range of reasons. These roofs require vigilant maintenance, and one of the forms of this maintenance is through a layer of roof coating. Roof coating extends the life of these roofs, prolonging the security of the original installation. Roof coating reduces heat transfer into the building, decreasing thermal shock (thermal expansion and contraction of the roof membrane), and helps to mitigate leaks. Most flat roofs are not perfectly sloped, thus great attention and care must be taken to select a quality roof coating for maximum rain insurance.
How Much Does Roof Coating Cost?
Roof coating can cost around $1,000 to $2,500 for professional application/installation. One gallon of roof coating costs around $15 to $30 dollars per gallon, with one gallon covering one hundred to one hundred and fifty square feet. Every roof is different, and depending on the area of the country you are in, the roofing type, type of sealant product used, and the complexity of the application, the price will vary.
How Do You Apply Roof Coating?
Laying down a professional coat of cool roof coating is ostensibly a job best left to the professionals, but if you are an aggressive DIY homeowner, applying elastomeric cool roof coatings can be accomplished. Competent results require great attention to detail, care, and a few special tools. Don’t forget to budget for an adequate amount of time to administer and apply the product properly. Product warranties may be limited or voided if improper application is utilized.
Inspect the roof membrane for cracks, tears, blisters, evidence of ponding, and more, If the roof is already coated, evaluate the condition of the coating. Pay attention to areas around roof penetrations, such as areas with vents or skylights. If the scope of the roof is in poor condition, do not attempt a roof coating.
If the roof is in good condition, purchase the necessary materials. A roof coating can be completed over a two-day weekend in warm weather. Dry, sunny weather over seventy degrees is ideal. You will need to prep the roof beforehand with a vigorous cleaning, and then repair and seal all roof penetrations. Consult your local hardware store with the measurements for your roof to receive appropriate amounts of materials, and advice.
How Much Roof Coating Do I Need?
Before you venture to the store to purchase roof coating, you will need to procure a ladder and start doing some measurements for your roof. Knowing the square footage of your roof will help, and it will help you know how many pails of elastomeric roof coating you need. Measure the length and width of your roof to determine the size in square feet. The formula is: length x width = square feet. Essentially, every square one hundred feet will equal one gallon of coating.
How Much Does it Cost to Recoat a Foam Roof?
Usually, you will want to recoat your roof approximately five years after the first installation. At five years, the roof will still look like new, but in order to maximize your ultimate maintenance goals, you will want to meet this deadline. A coating upgrade usually costs about a quarter of the original roof cost. The recoat cost goes up incrementally with time for those who wait longer than five years to recoat. That means if new residential construction has occurred in your area, expect roofers to arrive in your area for flat roof maintenance.
Roof Coating to Stop Leaks
If you do happen to notice that your asphalt roof is experiencing a leak, using a roofing sealant is a short term fix. Over the long term, you are going to want to use a more permanent solution, such as a roofing repair. In the meantime, using a roofing coating is a possible solution. Once you identify the source of the leak, the roof coating you select will have to be specific. The factors depend on the material of your roof, the flashing, and the projected area for repair.
Roof Coating and Sealer
Roof coating acts as a type of sealer. There are four main types of roof coating: acrylic, asphalt, polyurethane, and silicone. The type of roofing sealant you ultimately settle for will match the purpose. If you are looking to seal exterior siding, windows, and doors, you will want exterior caulk, which is usually made of polyurethane. For matching the texture of materials like stucco or rough-sawn wood, textured caulk is a good choice. For interior painting projects, you’re looking for a latex caulk. If you have cracks in your concrete, you will want to settle for a caulk that has eminent flexibility, so polyurethane, acrylic latex, or a hybrid of the two will do.
Roof Coating vs. Replacement
One of the reasons why many building owners select a silicone coating to their roof is the fact that it accomplishes many of the goals of roof replacement for approximately half the cost. It is common for a building owner to refrain from full roof replacement in lieu of repairs. This is a poor alternative and does not fix the problem. By contrast, installing a silicone roof coating can take your current roof, which is failing, and turn it into one of the highest performing roofs available. This process can extend the life of the roof up to twenty years.
Roof Coating Benefits
In conclusion, there are many roof coating benefits that commercial and residential customers should consider:
- Inexpensive to install.
- Once properly installed, extend the life of your current roof.
- Can be installed without disrupting everyday operations.
