One of the ways to provide you with superior service is to help educate you on certain construction topics. The following excerpt is a great piece that better explains what is involved with concrete tile roofing.
Concrete tile roofing is a great replacement for old shake roofs, as well as a wise choice for the new home builder. Several styles are available; from the classic Spanish or Mediterranean look to even some very nice shake look-a-likes. Clay tiles fall into this category as well, as they are another natural looking product that will last for decades. Specially designed light weight tiles are also available for homes that aren't specifically engineered for tile. Most homes can have this product installed with little to no modification.
Most of the products come with a manufacturer's 50 year or lifetime warranty, many of which are transferable to the next owner. What most people don't realize is that this warranty is only for the concrete or clay tiles, not the actual roofing system. This is a very common misconception that, unfortunately, many people start finding out about when their "lifetime" tile roof begins developing leaks and other major problems when it is as early as 10 years old.
Obviously the main reason this happens is that somewhere along the line, someone wanted to save money. Whether it's the homeowner trying to save a few bucks or a "thrifty" builder looking to cut some corners, the end result is usually the same; you almost always get what you pay for.
Here are a few things to look for in your roofing bid:
New Eave Flashings- A new drip edge flashing will protect your eave and fascia boards from the elements.
Anti-Ponding Devices- Many of the older systems simply nail a piece of lumber at the eaves to raise the first tile course so it is at the same angle as the next courses. The causes a problem by creating a blockage that will dam water and cause wood rot problems. There are several alternatives to this, including foam wedges, specially designed drip edge flashings and eave closure strips such as bird stop metal or tile riser metal.
Eave Closure Strips- Commonly referred to as bird stop or tile riser metal, these products perform the vital function of helping to keep birds and other unwanted critters from making their new home inside your roof. On clay roofs we use clay bird stop.
2 Layers ASTM 30# Felt Paper Underlayment- One layer of 30# is the minimum code. The double layer is created by laying the paper at 18" laps, giving the extra protection needed to make the roofing system a lot more durable. We also put a double layer underneath any valley flashings and around pipe flashings as well. All paper is nailed with 1" square head felt nails for increased holding power, not the cheaper roofing nails with the smaller 3/8" head.
Double Pipe Flashings- Many roofing systems simply have a galvanized pipe flashing with some mortar around it. Unfortunately this mortar cracks and disintegrates by the first ten years of service and begins allowing water underneath the tiles. Instead of mortar, we will install a 2nd flashing made of soft aluminum that will last the lifetime of the roofing system. This 2nd flashing will be sealed with a polyurethane sealant and painted to match the rest of the roof.
Diverter Flashings- Many skylights, walls and chimneys are flashed incorrectly because they don't divert the water back onto the tile. As the water runs down the side of these areas, it continues underneath the tiles onto the underlayment. A soft aluminum flashing should be installed to divert the water back onto the tiles.
Mortar/Ridge Closure- Many roof systems lack some type of closure at the hips and ridges. Wind blown rain can come right in and find its way onto the underlayment. We will install new mortar at these areas with higher profile tiles and there are some other systems available for the lower profile flat tiles.
Hand Nailed Tiles- Many tile roofs are installed with nail guns which can destroy the felt paper and crack the tiles. A special nail is required for these guns and is rarely used. The best method is always to nail the tiles by hand.
