The Twenty-Five “C’s” of Roofing

It’s hard to believe, but there are well over twenty-five roofing industry words that start with C. A more important fact is all twenty-five words are important roofing terms. But what do the words mean?

#1 – The Council of American Building Officials

A commonly used roofing “C” word is the acronym CABO which stands for The Council of American Building Officials. CABO merged with The International Code Council (ICC) not too long ago, and the ICC is now a nonprofit association that provides building safety solutions. These solutions are in product evaluation, accreditation, certification, codification, and training. Just as important, ICC develops the codes and standards that worldwide construction projects are held to in safety and sustainability.

#2 – Cant

Cant strip is a piece of wood that is shaped like a triangle, or it is beveled. It is designed to serve as a gradual transitional plane between the flat surface of a roof deck. It can also used in rigid insulation and on vertical surfaces. In other words Cant is a support roofing material and prevents gaps.

#3 – Cap Sheet

Cap sheet is a proprietary coated sheet with granules used as the top ply of roof membranes. Basically, cap sheet protects against UV, weathering and physical damage.

# 4 – Cellulose

Cellulose is a newer roofing component used in the manufacturing of organic roofing material. It is a complex carbohydrate that is composed of glucose units. It is more commonly known as the main constituent of the plant’s cell wall.

#5 – Chalking

Chalking is used to show the degradation or migration of paints, coatings, or any other material.

#6 – Cladding

Cladding is a material used on exterior wall enclosures. Cladding can make weathered buildings look vibrant again and save in electricity when thermal or insulation issues are used with it.

#7 – Cleat

A roofing cleat is used to secure two components together. It is a metal strip, plate, or metal angle piece.

#8 – Closed-Cut Valley

There are two kinds of closed valleys. There is cut valleys, which are less expensive to install and are the most common; and woven valleys. The closed-cut valley is an application method where shingles on an adjacent slope are cut parallel and trimmed back two inches from the valley centerline. The woven valley shingles run from both roof slopes onto the adjacent slope, alternating with each course.

#9 – Coating

Coating is used with various products, but its use in roofing is to be spread over the surface for protection or decorations. Coatings are generally liquids, semi-liquids, or mastics. They can be applied as a spray or with a roller and cured to an elastomeric consistency.

#10 – Cohesion

Cohesion is the mutual attraction by which the elements or particles of a body or substance are held together.

#11 – Cold Process Built-Up Roof

Cold process built-up roof occurs with a continual but semi-flexible roof membrane. The ply or felts are laminated together with alternate layers of liquid-applied roof cement or adhesive. Then it’s surfaced with a cold-applied coating.

#12 – Combing Ridge

The combing ridge is the finished slate at the ridge of the roof, where the slates on one side stick out beyond the apex of the ridge.

#13 – Composition

Composition roofing is sometimes called asphalt shingles. It is the most common roof used on houses. Composition roofing is one of the lowest in cost and easiest to install.

The roofing uses for composition roofs run from home roofs to apartment buildings and church roofs. Composition roofing is available in many colors, has a flat profile, is algae-resistant, and has cellulose or fiberglass mats coated with asphalt and granules.

#14 – Concealed-Nail Method

This is when you use your asphalt roll roofing application to drive all the nails into the roof and cover with an adhered overlapping course. That way, the nails are not exposed to the weather.

#15 – Conductor Head

The conductor’s head provides direct runoff water through this transition component place between a wall scupper and downspout.

#16 – Coping

Coping is the covering that sits on the top of the wall. It is always exposed to the weather and made with metal or stone. It helps shed water back onto the roof through its sloped design.

#17 – Copper

This is the same type of copper used in cookery, but in this case it provides a natural weathering that is used in metal roofing. Most of the time, it is used in 16 or 20 ounces per square foot in thickness.

#18 – Cornice

The cornice is one of the most decorative roofing pieces. It is a horizontal molding or projected roof overhang.

#19 – Cove

The cove is a sealant material installed where vertical and horizontal planes meet. It helps to get rid of the 90º angle.

#20 – Cricket

A cricket diverts water around chimneys, curbs, and other roof elements. It is raised as a roof substrate or structure.

#21 – Cross Ventilation

In roofing, cross ventilation occurs when the air moves through the roof cavities. This happens when the air moves between the air cavity vents. What’s unique about cross ventilation is the airflow must be uniform. Otherwise, the roof will have hot spots develop in its sheathing, which reduces its efficiency.

#22 – Cupola

A cupola is at the edge, ridge, or peak of the main roof area. It is a small roofed structure.

#23 – Curb

A curb is a raised member that helps support roof penetrations. This includes being used in skylights, mechanical equipment or hatches needed on the roof. It is above the roof’s surface but relatively low in height.

#24 – Cure

Curing a roof means you are processing roofing material to form permanent molecular linkages by exposure to the chemicals, heat, pressure, or weathering.

#25 – Cut-off

A cutoff is a permanent detail that seals and prevents water movement in an insulation system. It basically isolates sections of the roofing system to help disperse the weight of water in one area.

The Ten Must Ask Questions to Your Roofer

The Ten Must Ask Questions to Your Roofer

Almost everyone eventually needs a new roof. When you need a new roof, you are usually already dealing with a roof that has issues. So, you begin to scour the internet to find a reliable roofing company. If that isn’t bad enough, most people know little about how to build or repair a roof and have to rely on a roofer’s expertise. It can be a very unnerving issue. It helps if you know what to expect or what questions to ask.

Is there an internet resource you can use that can help you find roofing contractors in your area? Or are there common questions about the roofing materials and process you need to ask? The answer is yes to both those questions. Learn more about the questions you need to ask a roofing company before hiring them in the informational guide that follows.

How Long Has Your Company Been in Business, and Are You Licensed?

The first question to ask roofing companies is about the experience the roofing contractor has. The roofing company should be licensed in your state as this is a requirement in most states. If your contractor has a licensed roofing company you know they are held to the state’s standard and must meet codes, rules, and regulations. Having a licensed roofer install or repair your roof also allows you to use legal recourse, if and when needed.

Is There A Warranty on The Work You Perform In Addition to The Roofing Material You Install?

You should never hire a contractor who doesn’t warranty their work and the products they are installing on your roof. Most roofing material and products carry at least a twenty-five-year warranty. Every roofing contractor has different warranty policies, but it behooves you to use a roofing contractor who does warranty the quality of their installation work.

Do you Have Workman’s Comp and General Liability Insurance?

Every roofing contractor should have a workman’s comp for the employees or subcontractors. There are roofing contracting companies who don’t carry General Liability Insurance as they believe nothing will ever happen. However, you can’t afford to believe that. You will need to make sure your homeowner’s insurance is up to date and only hire a roofing contractor who has both workman’s comp and general liability insurance. Make sure they give you a copy of both policies.

Is Drip Edge Metal Installation Part of my New Roof Contract?

There may be nothing worse than installing a new roof, and finding out the drip edge metal wasn’t part of your roofing installation package. The next time it rains you’ll have no system in place to guide your runoff into the gutters. Drip edge metal also helps protect your wood or your roof’s fascia. Many roofers don’t include it, so you almost always have to ask for it to be installed if you want it.

Ask to Speak to and See Some of Their Past Roofing Projects

You should never hire anyone for any project without checking their references. You need to start with a quick online check and notice any comments or reviews listed underneath the company name. Then look up the roofing company to see if they’re listed on the Better Business Bureau.

You also want to speak to a few past customers on the phone, and if you have time, drive-by their house to review the roofer’s final product.

What Measures do You Take to Protect the Driveway, Lawn, Home, and Property from Damage While You Work?

There are have been many recorded instances where roofing contractors damage a home or property while they work, and the homeowner is left footing the bill to fix the damage. You want to ask how the roofers will access your roof, what kind of ladder stabilizers they use, and where they store their equipment as they work.

Who Do I Communicate With About the Project When There Are Issues, or I Have Questions?

There are times you may have questions about what you see the roofing workers doing as they install your roof. Or you may have questions about the amount of time it is taking for them to finish your job. No matter what your issue or reason, you need a roofing company liaison to communicate so, you can have peace of mind. There are always last-minute issues and its best to avoid serious headaches by having a designated person to go to for your concerns.

Get a Written Estimate

No roofing job or contract should begin without you holding an agreed upon written estimate. You want to know how they bill you, and you also want to know what can result in the written estimate deviating from the final price.

How Long Will It Take to Finish My Roof And When Can You Schedule It?

When replacing a roof, it can take anywhere from a couple of days to a week or so. Replacing a roof is a labor-intensive project that requires several workers at a time. Roofing contractors have to deal with weather delays. The time it takes to finish your roof installation project has many moving parts, so it’s important to be aware of things out of your control when you schedule a roofing project. Also reputable roofers may have full schedules. Make sure you find out when they can firmly fit you in and try not to accept any tentative start dates.

Eco-Friendly Company and Materials

Many people want to know if the roofing company they are hiring is eco-friendly. You may want to save your last question for asking if the company uses recycled content material in your roof? You also may want to find out if the roofing product used is recyclable at the end of its life when the roof needs replaced again in 20 or 30 years?

You’ve asked your roofing contractor all the questions you need to, and you’re ready to move forward with your roofing project. Be alert to any hidden costs you see in the bill you were not given in your estimate. Accept nothing less than what was agreed upon because your roof is one of the most important aspects of your home. When you need to check out roofing contractors in your area, reach out to us.

The Five Most Common Roofing Materials and Their LifeSpan

The Five Most Common Roofing Materials and Their Lifespan

Some of the most important considerations you have when replacing or building a roof is what material to use, how much will it cost, and the roof’s lifespan. Quality materials used in roofing usually lead to more expenses. But, a better way to look at your roofing project is quality materials lead to a roof’s long lifespan.

Almost every weather condition nature throws at roofs has an impact on the roof’s lifespan. The roof’s color, material, design, and location all play strong roles that can affect the roof’s durability. Even when you use maintenance-free roofing material, you may still need to perform maintenance, and even do small repairs on it from time to time. But there are roofing materials that have long lifespans and reasonable costs. The guide below gives you information on the five most commonly used roofing materials.

Asphalt Shingles

Asphalt shingles are one of the most common roofing materials used on buildings and homes because of their low cost. Asphalt shingles usually offer a guaranteed life span, which also makes them very popular. Asphalt shingles are used by countless major corporate buildings and on residential homes throughout the United States and Canada. There are also three different types of asphalt shingles you can use on your roof.

  • Dimensional shingles – these are called laminated shingles most of the time
  • 3-tab shingles
  • Luxury shingles

The added characteristic wanted and needed the most with asphalt shingles is lamination. Laminated asphalt shingles are engineered to resist storm winds, rain, sleet, snow, sun, and natural degradation caused by being outside exposed to weather elements. The cost for asphalt shingles ranges from $65 square foot to over $300 square foot. On average, to install the roof you will pay around $2.25 per square foot.


Manufactured composite shingles can be reinforced with recycled materials or fiberglass, and will still look the same. The recycled process makes composite shingles eco-friendly, which is very popular. Composite shingles last about twenty years, but you should never use composite shingles as your roofing material if you live in a high wind impact area.

Composite shingle roofing is the most popular of all roofing materials, found on more than 80 percent of all homes. Composite shingle’s popularity comes from its relatively low cost and long lifespan. Remember, these are engineered shingles, so no matter what color or material you want your roof to look like it can be done. Their fifty-year long lifespan adds to the roofing materials’ popularity. Composite shingles’ average cost ranges from $5.75 to around $14.00 per square foot installed.


Sometimes it is puzzling as to why people want tile roof material due to its high-cost. Tile roofs are known for their beauty. They can last up to 100 years, so their durability and lifespan are without question one of the best roofing materials you can use. But it’s important to take note that tile roofs use mortar bed systems most of the time. By being set on mortar bed systems they tend to fall and gap.

The component that makes up tile roofing material is made of terracotta most of the time. The terracotta is very heavy and also fragile. But terracotta is popular because they retain their color for decades or sometimes a hundred years or more. Tile roofs are fire resistant and in the world of roofing, are considered at only a mid-level cost roofing product. Tile roofs can cost anywhere from $800 per square foot to install. They sometimes can go as high as $1000 per square foot. Because they require expert installation your installation costs will be between $100 – $150 per square foot.


When slate is used correctly as a roofing material there is not much that can compare to its beauty. Slate roofing material’s lifespan can be as high as seventy-five years. Slate is a more sophisticated roofing material than tile but similar in weight constraints. Slate needs sturdy and expertly installed fasteners and nails. Slate roofs are eco-friendly and come in any color you want. Unfortunately, slate roofing material is known for its expense. It will cost you five times over what an asphalt shingle does. What’s more, finding an expert slate roof installer can be challenging depending on where you live.

The average cost of an experienced slate roof installer charge is around $5.00 per square foot. The slate tile material has an average cost of about $5.00 – $6.00 per square foot depending on if you are using a popular or rare color and pattern. Slate roofs are a worthy investment because it adds value to your home and is one of the most beautiful roof styles.


Fiberglass is common and popular as a roofing material because it is versatile. Once your fiberglass roof is glazed, it’s also water and shatterproof. Fiberglass roofs remain strong and have a long lifespan. Fiberglass roofs are sold in sheets or panels. Uniquely, they are resistant to rust or mildew and should last about thirty years.

Fiberglass shingle costs average around $40 – $200 per square foot, and for installation, an additional $80 – $200 per square foot is needed. It’s important to note, fiberglass and asphalt shingles are very similar, but there are characteristic cost and durability differences. Fiberglass is more sturdy than asphalt shingles, and you can see the difference between the two through their cost.
