Roof Coatings

The roof coatings experts at Master Roofing of Central Florida, Inc. can help you make the right choices for you and your roof. There are a number of different types of roof coatings and a myriad of roof surfaces that can be coated. Consult the experts at Master Roofing of Central Florida, Inc. to be sure that you consider all aspects of roof coatings.

Like painting a car, proper surface preparation is the critical step in roof coatings. Whatever you don't take care of in surface preparation will show up later as a big and potentially very costly mistake when roof leaks cause damage.

We're The Roof Coatings Experts
Roof coatings system planning looks at the type of surface, proper surface preparation, thickness of the basecoat, UV (ultraviolet) protection requirements, topcoat choices and thickness, number of coats, drying time between coats, and application methods. Proper planning for your roof coatings projects will keep quality up and costs down.

What cleaning method is needed? Will some areas need reinforcement with mesh fabric to resist movement and provide a good adhesive base for the roof coatings? Should low ponded water areas be double coated prior to basecoat application?

Factors in basecoat selection include mil thickness of the basecoat, inclusion of UV protection, and basecoat color (should be a different color than the topcoat so you can monitor the thickness of the remaining roof coatings).

How long should the basecoat cure before the topcoat is installed? What color topcoat would you select? Do you have to match a particular roof coating color to satisfy your homeowners association? Will you add granules to the topcoat?

Roof coatings are sprayed or rolled on. In most cases back rolling is recommended and each alternating coat should be applied in a crosshatched manner.

Single Ply Roofing

Single Ply Roofing, as its name implies, is a single layer of roofing material. This type of system is very popular on the East Coast. Single Ply Roofing has many advantages:

• Extremely Durable! Provides high puncture and tear resistance, excellent dimensional stability, and high tensile strength

• Excellent resistance to ozone and UV exposure, extreme weather conditions, chemicals, and fire

• No heavy equipment needed

• The membrane may be applied during times of inclement weather

• Reflective coating will reduce energy costs

• Offers the best of both worlds with the proven weathering of rubber and plastic membranes

All of the membrane sheets are supplied larger than conventional material - some are custom manufactured to individual job specifications.

There are three types of membranes used in our Single Ply Roofing systems. Our Master Roofing of Central Florida, Inc. technician will recommend the one best for your roof:

• EPDM (Ethyl Propylene Diene Monomer) is an elastomeric rubber roofing membrane

• PVC (Thermoplastic Membrane) is an energy efficient, fiber-reinforced, lightweight roof membrane

• TPO (Thermoplastic Olefin Membrane) is a high quality, reinforced membrane with superior tear strength and stability

Roof Preparation

In cities that require a roof removal, you may get a code variance that will allow you to apply this system over existing roofs. You will, in most cases, need to apply some sort of underlay such as fiberglass membrane or Recover Board.

Repairs

Master Roofing of Central Florida, Inc. will repair your existing roof as needed.

Application of Single Ply Roof Membrane

Application of Single Ply Roofing systems is a very clean process with no flaming torches, hot tar kettles, or strong fumes. There is less noise because heavy equipment is not required. The highly reflective white finish is environmentally sound, and will reduce your energy costs.

Your membrane will be attached in one of three ways:

• Fully Adhered System - a butyl-based adhesive that firmly secures the membrane to the substrate
  

• Mechanically Attached System - special fastening plates that are placed in various patterns based on building height, geographic locale, deck type, and building usage
  

• Ballasted System - loose gravel or interlocking pavers keep the membrane in place
  

Guarantee

This system will be guaranteed for five to fifteen years.

Tile Roofing

Tile roofing is beautiful but not waterproof. Tile roofing is a watershed and a decorative roof covering. The actual waterproofing is provided by the felt installed underneath the tile. Felt is organic and deteriorates over time, especially in the "Florida sun". This usually takes 12 to 16 years, depending on several factors, and then the felt must be replaced. We use peal and seal underlayment to give longer life on tile roofs.

Spanish tile roofing comes in a variety of styles and materials. They can consist of one piece "S" tiles seen on many modern office roofs or two piece roofing tiles, called "pans and tops" that you see in rustic, Spanish style homes. The tiles can be sand-cast, fired or made of lighter weight concrete.

We're The Tile Roofing Experts
Master Roofing of Central Florida, Inc. installs tile roofing according to the very specific installation Procedures of the Uniform Building Code. Our experience has been that 75% of the tile roofs we inspect do not meet the UBC because they lack the necessary perimeter mechanical fastening and other problems inherent in tile roofing systems. Call 407-521-8896 .

Tile Roofing requirements - contact us

Sooner or later all tile roofs will undergo a tile R&R (Remove & Replace). As a result when a 12-15 year old tile roof starts to leak into the interior space it is usually a lot bigger problem than is first thought. Often it is a telltale sign that the felt is ruined. Delaying the complete replacement of the felt beneath the tile will only result in ongoing frustration for the occupants, not to mention the damage to the interior contents of the building.

Careful planning with a competent "tile roofing" contractor is the answer. It is the only way to get your tile roof problem properly analyzed. If a new underlayment system is warranted, getting the proper system so you only have to do the job once is of the utmost importance.

Call the tile roofing experts today at 407-521-8896. We'll send a "tile roofing specialist" to review your requirements and provide you with all the information you will need to make an intelligent decision on your tile roofing needs.
