For more details just choose the type of roofing your interested in listed below. A brief description of these products has been prepared for you on these pages.

When laid up, these different blends of tile become a very beautiful roof. Roofs like these are sometimes made from the a local clay quarry, molded and fired right on site.
Below are other types of roofing products.

Slate Roofs

Slate RoofThe slate roof in my opinion can be one of the most interesting roofs to look at, With the installation options and the types and design, it is one of my favorites. Slate roofs,  by far, are one of the finest roofs to have. With a little maintaining, and correct installation, it can last 100 -150 years or more. Now most of us don’t live in a castle or a large steep house that slate normally is put on, but still there are many homes that slate is still a choice to pick from. It is such a visual roof, so the steeper roof, the better pleasure it is looking at it. The steeper roofs also carry the weight far better than lessor sloped roofs.

slate roof and skylight SWThe basic reason these roofs last so long is that, it is a tough, durable stone, quarried from places all over the world. The shale quarry’s where the slate is harvested, were formed many thousands of years ago from layers of fine clay and silt sediment. This sediment is compressed under high pressure for thousands of years, making it a very dense mud stone. This squeezing of the geological crystals causes natural parallel cleavage planes. Having these cleavage planes make the stone split very easily, almost like a cedar shake would split. Slate is perfect for making all kinds of slate roof tiles. Colors are native to the country ground of the quarry, with flashes of different minerals present in the ground, it can give the slates a variety of colors and blends or be the same color.

There are many size of slates, from thickness to width and length. Caution should be given to acquire the look you want. Skylights, walls, and pipe flashings are install similarly like a shake roof. The roof framing and sheathing should be of larger dimension because of weight.  I like to see at least 1″ x 4″ skip sheathing over a underlayment. If plywood is used it should be 3/4 inch in thickness. Nails should penetrate 3/4 of an inch into the sheathing. Most of the old slate roofs are commonly found to be nailed directly to the roof sheathing without any felt or underlayment.

This is an example of elevating the skip sheathing giving this roof air flow between the roofing and roof deck, as required by Title 24-6. It also allows any water that happens to get under the slates a free flow down to the eaves.

Slate Roof TurretThe underlayment for a slate roofs need to perform for at least 100 years. NRCA  { National Roofing contractors Association } recommends double felting with #30 on roof less than 20/12 pitch and slate should never be installed on a roof less than 4/12 pitch.

This Turret is about 20/12 pitch { 20 inches of rise over 12 inches of span. } and is a prime example of what a slate roof looks like close up. These roofs are near the top for cost but when you figure purchasing this roof once it will last over one hundred years vs buying a roof every twenty or thirty years, they can be a wise choice. Yes a mans home is his castle.

Cedar Shake Roofs

cedar shake roofing
Cedar shake roofs have taken a real popularity hit in the last few decades. Not as many people feel as comfortable with them regarding fire and life span. Cedar shakes and shingles are and have been one of the most popular types of roofing because of their durability.
Permanently fire retardant genuine cedar shakes with class A, B, & C ratings are available and still are being installed. These high quality cedar shakes after being milled are placed in pressure treatment cylinders where fire retardants are injected into the inner cells of the wood.
fire treated cedar shakes The material then goes through a polymerization process that locks in the fire retardants into the wood fibers. The shakes then are tested and certified by Underwriters Laboratories and the National Fire Protection Association.
These Heavy shakes to the left are being installed at 7.5 inches “to the weather” but typically are ten inch exposure. A #30 felt paper is used as a liner and laced with the shakes that results in a very good roofing system.

Asphalt Shingles

Roofing with Asphalt shingles
roofing with GAFThe composition shingle is one of the most used roofing product these days. There has been two basic types of asphalt shingles since I have been using them. The oldest shingles were made from layers of paper that is saturated with asphalt to make them waterproof, then granules are then embedded into the shingle to give it color and protection from the sun. These were called organic shingles. These shingle would tear easily and just barely last twenty years. The name we called them was 3 tab because of the cut outs in the shingle giving it three separate tabs.

Then there was the introduction of fiberglass reinforced shingles into the market. This shingle starts with a fiberglass mat coated with asphalt and then the embedding of the ceramic granules is done. These shingle are stronger. resisting tears and having a longer life span. The 3 tab design is still available but the asphalt shingle have mutated to a laminated type shingle. laminated shingles
Asphalt shingles are the most commomly used shingles because of their walkability, looks, cost and life spans.
The asphalt shingle has many designs to suit the most demanding architect. From the Certainteed Presidental, the Pabco Cascade, GAF Woodlands and the Owens Corning TruDefinition Max shingles.

Low Slope Roofs

Sprayed Polyurethane Foam RoofPolyurethane
Low Sloped roof are typically 2:12 or less pitch. This is a picture of a low-sloped roof with a Spray on Polyurethane Foam. SPF is sprayed on the cleaned and prepared roof deck. This product is a two-parts system that when both parts are joined together and sprayed on the roof deck, it bonds and fills all cracks as it expands 30 times its original liquid form when was first sprayed on. As it dries it creates a complete weather proof roofing system that adheres to the roof, walls, chimney and every surface it is sprayed on, to end up with a hard waterproof and insulated roofing system.GAF thermoplastic polyolefin (TPO) roofing
GAFTPO is a great option for a low-sloped roof. The real name is thermoplastic polyolefin and sometimes is called single ply. The roofing material can be mechanically attached, mopped in hot asphalt or fully adhered with adhesives. GAF thermoplastic polyolefin (TPO) roofing. This photo is of GAF EverGuard® Fleece-back TPO.
Tar and Gravel BURT and G
The Tar and Gravel or BUR { built up roof }roofs have been and still are a great flat roof application. The most common way of installing them is a fastened base sheet, the multiple layers of rolled roofing and hot asphalt with gravel spread on the finished layer to protect from the suns rays.
For home low slope applications like patio covers, there is available self addhesive modified bitumen. Basically a peal and stick product with a minerial surface. This is a little tricky to install because colder temperatures limits the use.

Standing Seam Roof Panels

metal standing seam roof Standing seam roofs are not only durable, they look great. The roof is made up of panels preformed and then vertically locking each panel together from one end of the roof to the other. These panels come in a variety of baked on enamel colors and in some cases traditional copper is used. Typically this type of roof is install in higher elevations and on steep roofs so when it snows the snow slides off the roof.

Stone Coated Steel Roofs

This DECRA Villa tile is made from aluminum-zinc alloy coated steel and is architecturally designed to look like the heavier concrete tile roofs but weighs only 1.6 lbs. per sq. foot. The coating is a stone chip finish that is acrylic bonded to the steel surface. The stone coating is what protects the product from the suns UV rays and resists fading.

Fire Proof Shakes

Like them or hate them, cedar shakes have been a very popular roofing product for many years. The past twenty or so years I have seen less and less of the cedar being used. I would have to say the fire issue is mostly the reason for it slump in market shares.The DaVinci Roofscapes
There have been many trys at making a fire proof “fake shake” with a large percentage of attempts failing. The natural beauty of a shake roof has been again duplicated using a polymer roofing materials. The DaVinci Roofscapes shakes protects you and home or business from fire, high wind and impact.

Concrete Tile

Bartile CottageThis Bartile roof is a beauty and anyone would be proud to call it home but the features of this roof that make it so unique are sometime not noticed. The Bartile company has many options that gives the home owner the chance to have a one of a kind custom designed roof. The choice of a three, four, five or more color blends are done at the manufacturers plant.
This guarantees a perfect blend and not left to the installer to mix these tiles on the jobsite. This customer wanted a aged look. Lichen and Moss Tile RoofHere Bartile, as crazy as that sounds, has added a splats of colors resembling moss or lichen. I think it looks great on this steep roof. The stagger on this installation also gives a old world cottage look but with a nice clean install. Bartile will remove the part of the water channel on the dropped tile installation like this one, for that clean look.
