Ask a TRI Expert: Roof Protection with Tiles & Underlayment

Have you ever wondered what types of questions people “Ask a TRI Expert“? This series, brought to you by the Tile Roofing Institute, allows anyone to ask anything about tile roofing installation, maintenance, etc. The Tile Roofing Institute (TRI) is a non-profit association of producers and associates of concrete and clay tile and is considered one of the leading experts in the industry. Here’s a recent question from a homeowner repairing their concrete tile roof, and the response from TRI President and Technical Director, Rick Olson.

Question:

“Recently during Hurricane Matthew a few of my Spanish style concrete tiles were damaged, cracked with some pieces missing. When the roofer showed up to repair the roof I was told that the tiles were only cosmetic and the real roof protection is underneath. I’m sure water gets under the tiles but I would think that most of the protection is from the tiles-70% or more. What is the truth about these roof tiles?”

Response:

“Historically (early 1900’s-1960) tiles that were installed were generally handmade or from home style manufacturing machines. With the low roof pitches in Florida, the wind driven rain could be allowed to enter the roof system, so the concept of a fully sealed roof system was used. 30-pound roofing felt was installed and a hot mopped 90 lb. cap sheet was applied. The tiles were then installed to prevent the UV from breaking down the underlayment.

Fast forward to the tiles made after about 1965. They were manufactured with newer high speed machines utilizing European technology that made a very dense tile that would prevent water intrusion through the tile (permeability) and allow tiles to become the primary water shedding component. In Europe, they were actually installed for centuries without any roof sheathing or underlayment, until recently.

The use of the sealed underlayment under the tile in Florida has continued over time because it provides a very good secondary barrier in the event there is either wind driven rain, or damage to the tiles during an event.

In summary, you are correct in your thoughts, but the stories passed down to roofing contractors carries the old thought from when tiles were not made to the newer standards. That said, there are still imported tiles that may not meet the requirements for permeability. All of the producing members of TRI will meet the criteria. If consumers choose to use an imported tile, we caution them to read and ask if the imported tiles will perform as the code requires.”

Slate Roof Tile vs. Concrete Roof Tile

Roofs serve to protect a building from natural hazards and extreme heat. That is why the type of roofing material used is fundamental to avoid any type of vulnerability to your commercial or residential project. With so many options available in today’s market, selecting the right roof covering for your structure can be difficult. So why not begin the decision process by exploring two roofing materials that have been around the longest?  Let’s review natural slate and concrete roof tile!

Natural Slate Roof Tile

Slate is a natural, fine-grained, metamorphic rock that is formed under intense heat and pressure underground. That rock is then split into smooth, flat pieces to form slate roof tiles.

Natural slate was used extensively in the Eastern US throughout history and remains a popular choice for authentic renovation projects – especially on historical landmark buildings. Most hardscape flat profile roofing products attempt to emulate the look of slate in some manner, whether it be texture or color.

Benefits. If installed correctly, slate can serve as a watertight roofing system that lasts the life of the structure with minimal maintenance. The dense tiles can help regulate the temperature of your home and reduce energy costs. Natural slate tiles are also fire resistant and environmentally friendly. It is a natural and recyclable product, emitting zero toxic substances into the environment.

Disadvantages. As mentioned, natural slate tiles are extremely dense. They can weigh between 800 and 1,500 pounds per square (100 sq. ft.). This can pose a problem for homes that need a new roof, as typically they were not built to withstand this amount of weight. The expense of having a roof structurally inspected, and most likely reinforced, should be taken into account before having a slate roof installed. Another huge disadvantage is the high cost of slate itself, which may make it unattainable for many. Due to budget and weight constraints, emulates and alternatives have been produced, including synthetic slate. This product is lightweight and cheaper to install than natural slate; however, it is typically made of plastic and is relatively new to the market, so durability and longevity have not been proven.

Concrete Roof Tile

Concrete roof tile is the world’s most widely trusted roofing material dating back as early as 10,000 B.C.  It has graced the roofs of homes, houses of worship, universities and commercial structures of the past to the modern day. Made from a natural mixture of cement, sand, water and oxide, concrete roof tiles provide countless design possibilities as they are available in a variety of sizes, profiles and colors, making it easier for consumers to select the perfect tile to match any architectural style.

Benefits. When installed correctly, concrete roof tiles can withstand the harshest of weather conditions. In fact, most concrete roof tiles, such as those manufactured by Eagle Roofing Products, are noncombustible, severe weather tested and freeze-thaw tested.

Due to the installation method and the inherent properties of concrete, concrete tile roofs can help reduce energy costs by allowing air to circulate under and through the tile, reducing the heat transfer into the attic. If any tiles happen to chip or break, a replacement tile can be easily slid into its place. Due to how they are installed, individually – instead of in sheets or overlapped, along with the inherent thermal insulating properties of the raw materials, concrete tile roofs reduce energy costs by allowing air to circulate under and through the tile, reducing the heat transfer into the attic. In an effort to further enhance energy efficiency, concrete roof tiles are also available in highly reflective colors that meet various cool roof requirements for LEED, Energy Star and more.

Two more added benefits to take into consideration? If any tiles happen to chip or break, a replacement tile can be easily slid into its place making roof repairs easy. Also, as touched on above, some concrete roof tile manufacturers have found innovative ways to give consumers more options by making their tile look like wood shake or slate. Eagle Roofing Products, for instance, has come up with a Textured Slate product the embodies all of the beautiful characteristics of slate but at fraction of the cost of real or synthetic slate.

Disadvantages. Like natural slate roofing, concrete tiles are heavy, which means if you need a new roof, you may need to have your building structurally inspected prior to installation. However, concrete tiles are lighter in weight and less costly to install than natural slate tiles. In addition, under certain environmental circumstances, concrete roof tiles can become algae prone. Although this does not affect the tile’s durability or energy efficiency qualities in any way, aesthetically, a homeowner may need to hire a professional to pressure wash the roof tiles periodically.

Making a decision between two superior roofing products that last a lifetime can be difficult, but, now that we’ve compared natural slate tile to concrete roof tile, you should be able to identify which of the two will work best for your next project.

Roof Repair vs. Roof Replacement

Think of your roof as a system; a system derived of different types of barriers that work together to protect you and your home from the outside elements. Because your roof plays such a key role, it’s important to have it inspected from the inside out, at the very minimum once a year – especially as it ages or after a severe storm. Below are a few tips that will help you quickly identify the status of your roof and whether or not it might need to be repaired or replaced.

If you have a concrete tile roof, the first thing to note is if you have any broken roof tiles. Concrete roof tiles act as the shell, or the first line of defense, within the roofing system, protecting the underlayment and wood decking that lies beneath. If you notice broken tiles, contact an insured and bonded roofing contractor immediately to have the pieces replaced. Often times, it can be difficult to spot broken tiles from ground level and if they go unnoticed or unfixed, bigger issues within the roofing system may arise. These areas can act as potential points of entry for animals and allow for water to penetrate the underlying layers of the roof, creating water spots on the ceiling, fascia or soffit. If caught early with minimal damage, a simple underlayment or flashing repair in the faulty area will suffice. Other cases that warrant repair for any roof type would be: sagging gutters, pooling water on your roof, damaged soffits, cracked flashing or recent accumulation of rainwater in your attic.

As for roof replacements, this usually depends on the condition of your underlayment. Underlayment serves as a secondary level of protection from deterioration, moisture, and leaks that can directly affect your roof deck. This portion of the roof does have a lifespan, so if you experience problems with multiple or widespread leaks, your roofing contractor may recommend that you replace the entire roofing system. A roof replacement may also be necessary if it has sustained extensive damage from rainstorms, long winters, and heavy winds. Unfortunately, wear and tear is unavoidable. Last, if your roof needs replacing, consider exploring all of the different options of roofing materials available. A concrete tile roof, for instance, is known to significantly increase curb appeal and last the life of the structure compared to the 20 year lifespan of an asphalt shingle roof.

With each part of the roof playing such an important role, it is recommended that you have a licensed, insured and bonded roofing contractor inspect your roof once a year to conduct any necessary maintenance or assessments. Some roofing companies offer a free roof inspection which may reveal previous storm damage that could be covered by your homeowners insurance, while others may offer financing for repairs not covered by insurance. It is suggested that you get 2-3 estimates that include the scope of work, pictures of all areas and damage, as well as a full breakdown of charges.  Most importantly, do not try to fix it yourself. When it comes to maintaining your investment, the smartest money you spend could be on a roof repair or replacement.

ASK A TRI EXPERT: TITLE 24 AND TILE FASTENING

Have you ever wondered what types of questions people “Ask a TRI Expert“? This series, brought to you by the Tile Roofing Institute, allows anyone to ask anything about tile roofing installation, maintenance, etc. The Tile Roofing Institute (TRI) is a non-profit association of producers and associates of concrete and clay tile and is considered one of the leading experts in the industry. Here’s a recent question from a homeowner repairing their concrete tile roof, and the response from TRI President and Technical Director, Rick Olson.

Question:

“I have a contractor who is trying to meet Title 24 requirements on a new project. They are asking about installing 1/2″ Polyiso insulation over the roof sheathing before applying 2-layers of 30# felt and concrete S-tile.

We have never installed insulation this way. It seems that having to nail the tile through the insulation to get to the plywood sheathing would detract from the holding strength of the nails. Can you let me know if this would be acceptable to install a tile roof with this system or do they need to find another way to meet their T-24 requirements?”

Response:

“As you have identified, title 24 does create some challenges for the roofing professional. In essence there are prescriptive and design options for meeting the requirements that include the building design, A/C, lights windows and roof systems. For tile, they have generally been met through using higher solar reflective colors that have been formally rated by the Cool Roof Rating Council (CRRC). The air space above the sheathing called the Above Sheathing Ventilation (ASV), will also increase the thermal barrier and has an R-value in the equation. With some designers, they are trying to maximize additional benefits by looking to add thermal radiant barriers either above or below the sheathing. In your case they are trying to add insulative board above the sheathing.

The challenge is that such materials are not code approved substrates for our tiles to attach to. The fasteners would need to be of sufficient length to penetrate 3/4” into the actual sheathing. We call these pre-engineered systems and look to the manufacturer of the insulation board to provide proper fastening requirements.

As the tile industry, we have done extensive uplift testing on traditional fasteners into plywood, but do not have testing to support the use with Polyiso style of insulation materials. We have raised our concerns to the California Energy Commission to look beyond just the radiative properties and review the actual installation requirements for wind, fire, and seismic code requirements as well.

I hope this helps answer your question. I know it is a little more detail than required, but it helps show the challenges we are facing as the Title 24 raises the thresholds.

In summary, we do not have a formal installation detail for the installation you are referring to. The local building official may have established criteria for use, but would suggest you ask the designer to call out the length and size of fastener they would require. The best result would be to just use tile and if they wish additional levels, use a radiant barrier underneath the sheathing.”

Ask a TRI Expert: Loading Tile

Have you ever wondered what types of questions people “Ask a TRI Expert“? This series, brought to you by the Tile Roofing Institute, allows anyone to ask anything about tile roofing installation, maintenance, etc. The Tile Roofing Institute (TRI) is a non-profit association of producers and associates of concrete and clay tile and is considered one of the leading experts in the industry. Here’s a recent question from a home inspector, and the response from TRI President and Technical Director, Rick Olson.

A recent “Ask the Tile Roofing Expert” response by TRI President and Technical Director, Rick Olson, addressing concerns about tile loaded, but not installed.

Question:

“We have a buyer concerned about the time which the tile roof is loaded but not yet distributed. Is there a guideline? We don’t install the tile until the stucco and fascia paint is done…”

Response:

 From the tile standpoint, there is no time table for when they are installed. As we all know, tiles are strong and resilient and last a lifetime.

The possible issue with delayed installation is the length of time that the underlayment might be exposed to the UV rays. We always recommend that you check the underlayment instructions to see how long the material can be exposed prior to covering. In areas like Arizona, some of the lower end materials and some of the synthetics have a very short exposure time. In other areas, they may last longer. With so many different types in the market, we stress individual manufacturer standards.

If you have any installation or other tile questions, the Tile Roofing Institute’s website, www.tileroofing.org,  is a wealth of information. You can also find out when and where their next installation certification course will be held and contact them to request your own training.

Snow in the Attic? A Tile Roofer Shares the Surprising Cause

This week’s blog post comes from a guest author, the production manager for a roofing company in Colorado. Since most of the country is experiencing snowfall and freezing temperatures, it is crucial to know about the many reasons a tile roof can experience leaks during the winter.

In March 23rd, 2016 the Denver metro area experienced a blizzard that dropped up to 27 inches of snow in some areas and shut down the city for two days. This storm produced sustained wind speeds of 30-45MPH and two inches of water for every six inches of snow. It was wet and heavy and most Coloradan’s stayed safely tucked in their homes. Those who didn’t found themselves stuck in traffic for 4-6 hours.

Upon returning to work the calls began flooding in with reports of roof leaks. We scheduled our top repair technician to the issues and discovered the roofing systems were not failing at all. There were no leaks from ice-dammed valleys or water flooded penetrations as we would have expected with this heavy snow. Instead, we were just seeing piles of snow that had accumulated in the attics through the static vents (turtle and slantback).

snow-in-attic-768x435A few of the attics vents were installed improperly, causing some of the exhaust to act as intake, sucking in the snow. The snow then melted from the heat of the home, soaked through the insulation and then into the ceiling/drywall. Other homes had proper ventilation but, due to the severity of the blizzard, snow in large amounts was also being driven into the attics via the static vents.

In cases where the ventilation was improperly installed we recommended repairs to properly ventilate the attics, but in the other cases there was nothing we could do. Most home owners called their insurance companies to make a claim and mitigation companies to handle the water damage, which in some cases was significant.

The entire experience made for an interesting and stressful week but, more importantly, taught us so much about the importance of properly installing ventilation systems in a home.

May Your Holidays Be Merry, Bright and Safe: Tips for Smart Tile Roof Decorating and Maintenance

It’s the most wonderful time of the year! The holidays mean family, music, presents and, of course, decorations. But don’t damage your roof while decking your halls. Decorating your yard and home for the holiday season is a fun-filled activity but can also be dangerous and hard on your tile roof if you are not careful. While you’re up there, take advantage of the view and peek at a few maintenance issue-prone areas to be sure everything is in tip-top shape.

Below you will find a few tips for taking care of yourself and your roofing system during this season.

1. Don’t Step on Your Roof

This may seem counterintuitive to decorating your home’s exterior, but we always suggest you contact a licensed roofing contractor to do anything that means stepping on roof tiles. This is especially important during the winter months when roofs are subject to excessive moisture and ice. You will stay safe from harm, not to mention it can mean the difference between broken tiles and a well-maintained roof.

2. Don’t Put Holes in Your Structurelight-clip

Nails, staple guns, hammers, screws. What do these things have in common? They are all very good ways to put holes in things. However, you do not want to put holes in anything having to do with your roof. Clark Griswold could get away with it, you probably can’t. Not only does banging on your roof mean you can break something, holes are excellent ways to let unwanted moisture onto your roof deck causing costly repairs later. There are plenty of temporary options for securing lights like plastic clips you can research instead.

3. Keep an Eye Out for Icicles

While icicles are beautiful and remind us of some of our favorite holiday movies, they can be indicative of ice dams: chunks of ice that form at the edge of a roof under certain winter conditions. An ice dam can damage both your roof and the inside of your home while also putting gutters and downspouts at risk. So, while you’re stringing your lights and finding the perfect spot for your Santa display, make sure you call a licensed roofing contractor to inspect the area if you notice a sudden patch of icicles.

4. Bring a Friend

Perhaps one of the most important pieces of advice when doing anything dangerous or tricky with your home is to make sure you have someone with you while you’re working. Not only does it make things more fun but it also gives you a second pair of eyes for potential issues and another set of hands to secure ladders and other tools.

We hope these tips are helpful. As always, you can visit the Tile Roofing Institute at www.tileroofing.org for tile roof maintenance tips and to search for a certified contractor in your area. You may also contact a knowledgeable Eagle Roofing Products Account Representative at www.eagleroofing.com if you have any questions.

Happy Holidays!

For Craftsmanship and Beauty that Transcends the Ages, Choose A Tile Roof

A true “European Trained Craftsman”, Martin Leska graduated with honors from a four-year trade school and moved to the United States in 1998 from the Czech Republic. His plan was to be a climbing guide and ski instructor, which he did for a while in Jackson Hole, Wyoming. However, his impressive skills and training in building and restoration led him to eventually start Leska Restoration LLC. Martin still has an insatiable appetite for learning more and, lucky for us, he likes to share his knowledge and experience with others.

castle_neuschwanstein-1Martin’s first roofing experience was a 14th-century castle restoration when he was 16 years old. He had spent the summer working with his father and the last revision to the castle had been in the 18th century, meaning the work he was restoring was 200+ years old. “During communist occupation this castle drastically deteriorated,” Martin said. “This structure survived mainly because of the tiles that were installed.”

“A very exciting part of this work was to look for small evidence left by previous roofers like hand signed note, a lost chisel or hammer, etc.” After a summer of hard work, Martin had the chance to become a part of the history. “I specifically remember the pride when each worker was asked to write his name and signature on the actual plaque we hid inside the roof, and my father saying that our grandkids will most likely be next to find this.”martin-leska-1-300x254-1

His passion for quality installation details reflects Martin’s respect for the potential longevity a properly installed tile roof can deliver. “Tile roofs are designed to last a lifetime. So why wouldn’t you want such a roof on your home or business? I know I would,” Martin shared. He added, “In my opinion tile roofs are by far the best roofing product you can install on a steep slope roof. I think that even in the 21st century there are many reasons we love tile; it’s man-made, extremely energy efficient, comes in a huge range of styles, shapes and colors, is extremely long lasting and is Class A fire rated. I love having the variety to show my clients when selecting a tile roof. It’s excellent from hot climates to even extremely cold or snowy climates.”

Martin’s skill level is equaled by his energy and passion. A mountain climber, downhill skier and mountain biker, everything he does is done with enthusiasm. The commitment to improvement is a constant. “Europeans are onto something by over teaching as it’s proven that we forget 30-50% of what we learn. It takes new training every year and time working in the trade to hopefully earn ‘master craftsman’ after five years with the help of the Tile Roofing Institute.”
