Roof Covering Materials

There are seven Basic elements in your Roofing. The Support, the Deck, the Underlayment, the Roof Covering, the Flashing, the Ridge Vents, and the Design.

1: The structure under your actual roofing; the support beams (rafters, trusses), typically in the attic, that support the roof structure from underneath. You need to conduct a thorough review of your homes attic, or have it done by a professional and go with them to see the condition for yourself. If your supporting structures are warped, rotten, insect ridden or otherwise damaged, you should non consider replacing whats above those structures until you address the quality and strength of your roofs supports.

2: The Deck. which is sometimes called sheathing; thats the wood (typically plyboard panels) or metal sheeting attached to these supports. When you finally choose a roofing contractor and sign a contract, be sure it specifies the cost that contractor charges to replace any panels. Neither you nor your declarer will know how many, if any, panels are damaged and in need of replacement until the declarer removes the old roof covering materials. We suggest that you ask your contractor to specify in the contract how many panels theyll replace for free, along with the cost of additional replacements. This avoids confusion or any feeling that you are being taken vantage of with hidden costs.

3: The Underlayment. Its that material that looks like black paper or felt that covers up the Deck panels. Its often saturated with asphalt and provides wet and air barrier lay over the deck.

4: The Roof Covering. typically Shingles or Tiles. which are the exterior elements that come into direct contact with the elements. They are your homes first line of defense against rain, snow, ice, hail and high winds. In the United States, the most democratic covering by far is Asphalt Shingles. but roof covering can also be clay or concrete tiles, wood, metal or a synthetic material. For more about Asphalt shingles, refer to our Tutorial called Asphalt Shingles. Newer technology incorporating fiberglass has revolutionized asphalt shingles and greatly improved their performance and lifespan.

5: TheFlashing that waterproofs and weather proofs those parts of your home most likely to collect water or leak. This is especially true with anything that protrudes through your roof, like your chimney, skylights, exhaust events. Also, edges of your roofing or the valley where two sloping sections of roof connect are locations where water or snow will naturally accumulate, so flash can help protect you from that water.

Flashing is usually sheet metal that is bent and formed to provide that barrier between your roofing and whatever is protruding through it. It can be galvanized steel, stainless steel, aluminum, copper or some other metals, or a synthetic material. The formed flashing has to assure that water can not penetrate into or through your roofing system. Water can find its way into your roofing by gravity, by surface tension, or by high winds that actually drive it upwards.

6: The Ridge Vents that typically sit astatine the highest point of your roof, to allow for air flow through your attic. The Ridge vents help balance the temperature between outside and inside, which can help prevent damage like a warped deck or cracked shingles. A properly ventilated attic is a key to a healthy roofing system. These ridge vents atop your cap will be covered by materials that match the covering you choose. For example, if you cover your ceiling with shingles, there will be matching shake material covering your ridge vents.

7: The Roof Design: The shape, arrangement and slope of the different sections of your roof that determine its ability to shed water and withstand infiltration of air and moisture. For more details about Roof Design Terms, refer to our Tutorial called Roof Design Terms. For general purposes, just realize that the complexness of your roofs design, the more individual sections, the more protrusions, overhangs, et cetera, that more material and labor will be needed to properly complete your job.
