Roofing Terms

We want you to feel knowledgeable and confident throughout the roofing process, so we’ve listed below some of the roofing terms you’ll hear often when we discuss your roofing needs and options.

General Terms

Base Sheet: First layer of paper applied usually 3 times thicker than ply sheets and coated.

Built Up Roofing: A method of applying a roof system composed of various amounts of roofing paper (base sheet and ply sheets) to achieve a waterproof membrane. Can be hot applied or cold applied.

Cap Sheet: Surface sheet for most built up roof systems. Can be made of organic asphalt products or modified asphalt products.

Coated Sheet: Has an asphalt and sand finish. The finish keeps the asphalt or adhesive from seeping through sheet.

Granule Surfacing: A small granule product manufactured for roof surfacing. Size would be comparable to rock salt.

Gravel Surface: Gravel used for surfacing built up roofing.

Mechanical Fasteners: Roofing Nails, special screws and plates are used to fasten roof insulation and single ply membranes. Can be metal or plastic.

Modified: Cap sheet or ply sheets that are manufactured with a modified rubber product. More tensile strength than regular asphalt products.

Ply: Roofing sheets used in built up roofing systems, also referred to as “felt.” Can be made of organic asphalt products or modified asphalt products.

Polyester Membrane: Reinforcing membrane sheet used in the cold overlay system.

Roof Insulation: A rigid board of various widths from ½”to 6″, usually applied with some form of mechanical fasteners. When more than one layer is applied the second layer will applied with an adhesive, either hot or cold.

Single Ply Roofing: A rubber roof membrane that is applied with or without adhesive and is sealed and fastened at the laps of the material. Laps are sealed with heat welding using special hot air welders or special lap adhesive. Heat welding is the preferred method of sealing laps.

Tear off: Removal of existing roof membrane, necessary when applying new roof membrane in most cities in Central Florida.

Torch Applied System: The cap sheet has a coating of modified asphalt that is heated with torch just prior to application

Built Up Roofing

Probably the most popular roof system in use on the west coast, Built Up Roofing offers very good protection at a reasonable cost. As an option, Master Roofing of Central Florida, Inc. can install additional roof insulation under the roof membrane.

The term Built Up Roof refers to a system of multiple layers of roofing paper adhered either with hot asphalt or cold application cement, surfaced with various materials. Upon inspection by one of our Master Roofing of Central Florida, Inc. technical representatives, a recommendation will be made for your roofing needs.

Flat Roofs

Metal Roof Systems

Master Roofing of Central Florida, Inc. has found that there are several ways to approach metal roofs. After an inspection by our Master Roofing of Central Florida, Inc. technical representative, you will receive a custom recommendation tailored to your roofing needs.

Roof Preparation

Prior to membrane application, Master Roofing of Central Florida, Inc. technicians will power wash the roof with water at 3,000 psi. All rust is abraded and treated with rust inhibitor.


We will make minor sheet metal repairs, re-secure or replace all loose or missing fasteners, seal all vertical and horizontal seams, seal all penetrations, and encapsulate all fasteners.

Application of Metal Roof System

Once the cleaning and repair work is completed, we will spray-apply a first coat of synthetic rubber membrane, typically gray. Thickness varies depending on manufacturer and guarantee.

Final Coat

The finish coat of synthetic rubber membrane, typically white, is also spray-applied. Again, thickness varies depending upon manufacturer and guarantee.


Our various metal roof systems are guaranteed from five years to fifteen years.

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.

For roof coatings requirements, contact us today.

We will ask you a series of important questions to ensure that you get the results you seek. Put our experience and technical knowledge to work for you. Call the “roof coatings experts” at 407-521-8896.

We’ll evaluate these and many other questions to determine the best solutions for your roof.

There are some coatings you can apply yourself and some projects that are best done by a roofing contractor (like walking decks and cementatious topcoats). A qualified roof coatings contractor must also be used if you want a warranty.

Master Roofing of Central Florida, Inc.’s skilled staff is available 24 hours a day, 7 days a week, 365 days a year to plan, prepare, basecoat, topcoat and warranty your roof coatings. Call 407-521-8896 to learn more about the process.

Master Roofing of Central Florida, Inc. is skilled at All Types of Roof Coatings Systems. Let us take care of your roof coatings project. After all we are the roof coatings experts!

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.


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


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 .

For tile Roofing requirements, contact us today.

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.
