What Is The Best Tile Roof Underlayment In Arizona?

What Is The Best Tile Roof Underlayment To Use In Arizona?

Tile roofs can last up to 50 years in Arizona. However, the tile underlayment (felt/ tar paper) typically lasts 20 to 30 years. The tile underlayment will start rotting out when water gets under the roof tiles. The most common ways water can get under roof tiles are: clogged valleys/ roof flashing, broken tiles, or the roof tiles were not laid properly. Roof tiles are mainly aesthetic and act as a barrier between the tile underlayment and the roof tile.

The Arizona sun will destroy tile underlayment if it is exposed. Most tile underlayments cannot withstand the UV rays and start deteriorating rapidly. There are some tile underlayments that are designed for heat and sunny climates such as Arizona’s. So, let’s explore what is the best tile roof underlayment in Arizona!

The Different Type of Tile Underlayments Available

There are many different types of underlayments that can be used under concrete tile in Arizona. Here are are the most common: felt (SBS modified bitumen), synthetic, and self-adhering underlayments. We will talk about each type of concrete tile underlayment and determine what is best based on several factors: price, waterproofing, durability, and UV resistance.

Synthetic Tile Underlayment

Synthetic tile underlayments have been increasing in popularity in Arizona. However, in our opinion, they are not the best for material to use. In fact, we will recommend homeowners not to choose synthetic concrete tile underlayments. Let’s talk about why we don’t recommend synthetic concrete tile underlayments.

Price:

Some synthetic underlayments are more expensive than the felt type of concrete tile underlayments while other synthetics are cheaper. In fact, the material price can be double than of a felt type of underlayment. It would be cheaper to do two layers of felt than a single layer of synthetic.

Waterproofing:

Synthetic is the king of waterproofing capabilities and is 100% waterproof. How ever synthetics don’t self-seal around fasteners well (nails, staples, etc). This is the biggest issue when it comes to installing synthetic underlayment under concrete tile roofs. A concrete tile roof is comprised of

The underlayment is rolled out to cover the decks surface (keeping it waterproof) and nailed in place.
Batten strips (4 ft sections of 1×2 wood strip) are then nailed or stapled on top of the underlayment. They provide rows for the roof tile cleats to rest on and prevent them from sliding down the roof.
Then the roof tiles themselves.


Example of what is underneath a concrete tile roof
Installing a tile roof requires both the batten strips and underlayment to be fastened to the deck. So, with a synthetic underlayment that doesn’t automatically seal around the fastener’s penetrations, your roof is vulnerable.

The number one reason your concrete tile roof leaks is from water getting under the batten strips and going through the fasteners penetrations. Rubber modified felt papers will automatically seal these penetrations while synthetics will not.

So even though synthetics have a 50 years product warranty they are not the best tile underlayment for sealing the around the roof fasteners.

Durability:

As far as durability, synthetic roof material is quite durable. However, when synthetic tears it tends to tear in big sections. Synthetic concrete tile underlayments have a durable surface for foot traffic and have an excellent non-slip surface

UV Resistance:

Synthetic underlayment has very strong UV resistant qualities. When exposed to the direct sun, the underlayment can maintain a UV resistance from 6 to 12 months

Self Adhering Tile Underlayment

This underlayment is different from both the synthetic and felt underlayment because it has a self-adhering bottom. When installing a thin film is pulled away and the self-adhering bottom adheres to the roofs deck. The gives the advantage of leaving no roof fasteners (cap nails) exposed.

As you can see there are no exposed nails
Another benefit is most of the self-adhering concrete tile underlayments are rubber-modified and automatically self-seal around any nails pounded through its surface.

Price:

Self-adhering concrete tile underlayments are generally very expensive. It is usually around the same price to use synthetic underlayment.

Waterproofing:

This concrete tile underlayment is excellent at waterproofing. It has a lot of rubber inside of it and lasts a very long time. The seams are adhered together providing a waterproof surface.

Durability:

Self-adhering concrete tile underlayment is the most durable underlayment available in Arizona. Specifically, the brand, Boral Tile Secure, is the best concrete tile underlayment in Arizona for the durability factor. It can be used under metal roofs so it has a very high melting point. The surface is a non-slip and can handle high foot traffic which is good for the installers!

UV Resistance:

This material can handle a lot of UV exposure and lasts up to 6-12 months of direct Arizona sun! For UV Resistance, self adhering underlayment is the best underlayment for tile roofs in Arizona

Felt Type Tile Underlayment

Felt style underlayments have been around the longest out of the other two types. The are different class and types of felt that is used under concrete tiles in Arizona. Felts thickness are organized by weight classes ranging from 30# to 90#. Some felts are better than others.

Organic felt tile underlayment was used a lot 20 to 30 years ago. However organic felt is the cheap option. It tends to dry up and curl on the seam edges with age. Also, there have been incidences where roof rats have chewed up all the organic felt paper under tile roofs causing the roof to leak severely.

The better felts are the SBS Rubber modified bitumen. They are fortified with rubber which helps the underlayment lay flat on installation. The rubber also helps the material to self-seal around the roof fasteners.

Price:

The price for SBS rubber modified bitumen is the cheapest out of the other two options. In many cases, it is costs less to apply two layers SBS rubber modified felt than one layer of synthetic or self-adhering underlayment. For prices, felt is the best underlayment for tile roofs in Arizona.

Waterproofing:

Organic felt is not 100% water proof but the SBS modified version has more rubber in it allowing it to be superior at being waterproof. In Arizona, we have a very dry climate so SBS modified felt papers are more than enough to keep your roof dry. The composition of the SBS prevents it from rotting and deteriorating like its organic cousin.

Durability:

Felts are quite durable and can handle foot traffic quite well. The organic felts are less durable than the SBS modified felts. However, if the felt is installed in high temperatures the asphalt becomes pliable and the tar paper can slide when being installed. This is a hazard for the roofers since the tile roofs have a pitch.

UV Resistance:

Both the self-adhering and synthetic concrete tile underlayments have better UV resistance than felt. If a tile breaks on your tile roof and exposes the surface of the underlayment it is advised to get the tile replaced as soon as possible. The SBS modified felts are generally more UV resistant than the organic felts. Felt does not win the UV resistance test for underlayments in Arizona.

So, what is the best underlayment for tile roofs in Arizona?

The synthetics are out ruled out being that they are not self-sealing when a nail is pounded through their surface. In fact, we would NOT recommend synthetics under tile at all for Arizona. It is the best underlayment for under shingle roofs in cold climates.

One of the biggest faults synthetics have is not being repairable. One of the other two options if there is a premature leak then they can easily be repaired with more felt and tar. Many times a tile roof while start leaking in a high water flow area years before the rest of the underlayment needs to be changed. In our opinion synthetics are one of the worst underlayments for tile roofs in Arizona.

While self-adhering underlayment is the best tile underlayment in Arizona for durability, length of life, and UV resistance; an SBS rubber modified felt is our pick. A particular brand that we like the most is TU-43. Tu-43 lasts a long time, it can easily be repaired, has a rubber and fiberglass core, and it is has a reasonable price tag. Installing two layers would be cheaper than one layer of the self-adhering underlayment and last around the same time (some cases even longer).

So, if you need the underlayment replaced under your tiles in Arizona then we would recommend TU-43 as the choice of tile underlayment material. In our opinion, TU-43 is the best underlayment for tile roofs in Arizona!

Recognizing Tile Roof Problems

Recognizing Tile Roof Problems

Does Your Roof Need Repair?

If you think your tile roof has potential issues and you want fix those problems before they becoming bigger and more expensive issues, you’ll need to know what to look for. However, how can a homeowner inspect their tile roof and recognize the telling points that may show your roof has problems? Read on and we’ll help you with telltale signs that your roof may need some attention.

We’ll be discussing:

  • Physically inspect a tile roof correctly
  • Signs to look for when inspecting your tile roof

Remember, do not walk on your tile roof! To be safe, and to keep yourself from breaking tiles, we recommend you don’t walk on your roof.  This is especially important when you have a fragile clay tile roof. A good suggestions would be to use binoculars to inspect your roof from a distance from your yard or up on a secured ladder. Move the ladder to different view angles around your property to get a clear view of the entire roof.

Know What To Look For

1

Issue #1

Organic Debris
Between Tiles

Plant materials like mold and lichen or small branches and leaves can literally eat away at the underlayment.  This will leave your roof vulnerable and could void your roof’s warranty. If your tile roof is covered with lots of leaves, branches, and other organic debris, schedule a professional roofing contractor to preform maintenance as soon as you can.

2

Issue #2

Deteriorated
Flashing

Flashing is the material around any pipes, vents, chimneys or other penetrations on your roof. Decayed or poorly installed flashing can lead to water penetrating under the tiles and potentially damaging your underlayment.

3

Issue #3

Broken or
Missing Tiles

Missing or broken tiles will allow the tile roof underlayment (the roofs waterproofing feature) to decay. How does this happen? With a tile missing, the underlayment is now open and vulnerable to the weather and elements, like the hot sun, torrential monsoon rains and organic material from birds.

4

Issue #4

Moisture Damaged
Fascia Boards

Fascia boards are long, straight boards that run along the lower edge of your tile roof. These boards may need repair or replacement since they’re susceptible to moisture and can rot or decay. You should look for cracks and discoloration in the fascia boards around the roof.

5

Issue #5

A Sagging
Roof

If you think your tile roof is sagging, it may be that the roofing material that supports the roof has weakened.  Another reason could be that your roof has too much weight for the structure.  You may need to have a professional tile roof repair contractor bring in a structural engineer to analyze and recommend corrections to any structural problems your roof has.

The Underlying Issue

Deteriorating Underlayment

Everything we’ve pointed out so far is fairly easy to spot. However, deteriorating underlayment is harder to see because – as its name implies – it’s underneath the tile, which protects your roof from water penetrating through to the interior. Getting up on your roof and uncovering tiles to check your underlayment isn’t something you want to do yourself.

Here’s the most important thing to know – the underlayment on your tile roof needs to be replaced eventually. Usually between  12 and 20 years is about how long you can expect it to last in a climate like Phoenix.. If your roof is more than 12 years old and hasn’t been inspected in some time, you should contact an experienced tile roof repair company for a comprehensive roof inspection.

Does Your Underlayment Need Replacing?

The underlayment and flashings are critical on a tile roof because they are the primary water barrier to keep moisture from penetrating your roof. The tiles themselves are mostly for architectural curb appeal and helps to protect the underlayment. Since the tiles can last 50 years or more, your underlayment needs to be of similar quality. Usually, the tiles on the roof will outlast the underlayment and the flashings around your roof penetrations.

Whatever type of underlayment is deployed on your tile roof, the installation is as critical as the material used. It’s most important that proper sealing measures and flashing material is used at all penetrations for chimneys, skylights, pipes and roof vents. Valleys in your roof are also problem areas that need special attention.

The 3 Main Benefits of a Tile Roof

The 3 Main Benefits of a Tile Roof

More Than Just Good Looks

Tile roofing is most commonly installed on Southwest and Mediterranean style homes.  These aesthetically pleasing tiles are generally made of clay, concrete, or slate. However, benefits of a tile roof are more than just good looks.  Familiarize yourself with the selling points that make them such popular roofing options. Weigh those strengths against key factors to decide whether or not your home can benefit from a tile roof.

Here Are A Few Key Benefits of a Tile Roof

Durability and Long Lifespan

Clay, concrete, and slate roofs are extremely resistant to fire and resist rot, bugs, and most other pests. Most tile roofing will hold up to extreme heat and cold, making it great for use in almost any climate. Clay tiles are especially resistant to the corrosion from salty air, which makes them an excellent choice for properties located in coastal areas. Many kinds of roofing tiles can also brag of superior impact resistance, which makes them a superior option in areas that experience severe storms with hail or high winds.

Most tile roofs are found in the warmer warmer regions of our country, but they can be utilized in colder areas, too. When you’re installing a clay or concrete tile roof in a region with a colder climate, however, you should require materials designed to handle the expansion that occurs with freezing and thawing cycles.

Quite frankly, people are the biggest threat to tile roofs. The tiles are not typically designed to handle foot traffic and are prone to be being broken or chipped when people walk on them and are careless. This is why its important to hire an experienced, professional roofing contractor to do any repairs or maintenance on or around a tile roof – including cleaning gutters, maintaining chimney and other protrusion flashing, and routine regular inspections.

A roof made of concrete, clay, or slate could be the last roof you will ever need on your home. Clay or slate tiles can last as long as 100 years, while most concrete tile comes with a 50 year warranty. Slate is one of the most durable and long-lasting roofing materials of all, with a lifespan of 100 to 150 years or more.

Curb Appeal and Versatility

Concrete and clay tiles usually feature natural earth tones, a sand-cast or unglazed finish, and a classic curved shape. However, their design isn’t limited to just these Southwestern and Mediterranean benchmarks. Their casting allows for a lot of different style options which will suit just about any type of architectural taste.

Both concrete and clay tiles come in a large array of colors and can have glazed or unglazed finishes. The most common shapes are flat, fluted, and interlocking that can be used in a wide variety of home designs. Some tiles are made to look like wood shakes, for use on craftsman, rustic and  log homes. Others are designed to mimic traditional European properties. Natural slate tiles are used often as the roofing system of choice for victorian, colonial, and tudor architecture.  They also looks great on sleek, modern, contemporary homes.

Slate tiles give the distinct appearance of natural stone and have a lot of the advantages that clay and concrete tiles have, including durability and long lifespans. They’re very popular in northern Europe, and are often found on victorian and tudor style homes in the US.

Long Term Return on Investment

Tile roofs are one of the most expensive upfront for both materials and labor. Slate, as an example, can range from $1,000 to $2,000 per square (which is a 10-foot-by-10-foot section of roofing) installed and a tile roofing contractor that has experience working with the high-end material may also require more. However, over their long lifespan, concrete, clay, and slate tiles will offset their initial cost. Because of a high thermal mass, tiles do a great job of regulating the temperature of your property, thus helping you lower heating and cooling expenses. The durability and longevity of clay, concrete, and slate also mean that you save a lot of money by not having to replace your roof multiple times over the lifespan of your home.. As an added benefit in todays eco-friendly world, all of the materials used are environmentally friendly, easily recycled.
