If you opt to install your own roofing rather than hire a contractor, give yourself plenty of time to study all available materials before you do anything else. The majority of homes are roofed with fiberglass shingles, but there are many alternative roofing materials on the market today. Some of these include composition, clay and/or concrete tile, metal, wood, and slate.
Your choice needs to be based upon not only what is aesthetically pleasing but also what is structurally appropriate for your house. Of course, your budget plays an important part in what type of roofing material you decide upon, as well.
Heavy snow, rainfall, or frequent hailstorms in your area may eliminate the choice of clay tiles, for instance, as these are easily damaged (and relatively expensive, too!). However, cement tiles are much more resistant to these weather activities, as are composition shingles, which are created from asphalt and some other material used as a base (polyester, fiberglass, etc.), and then covered with a granular surface.
Composition roofing provides the best roofing for the money. And as for cement tiles, they may not be what you think: Cement tiles come in a variety of styles and colors which is expanding all the time, so do not think of them simply as ugly gray slabs of material on your rooftop.
Lay Material Out First, Mark, Then Install Tarpaper
After you have made this important first decision and obtained your outer layer of roofing material, the next step is to lay the material out on the roof and mark it using chalk. Instructions come with whatever material you use, and it is important to follow these directions to get the best results, especially with how it will look once it is permanently in place on your house. After you have laid out your material and marked it clearly remove it from the rooftop for the next step in your roofing installation.
An underlayment of tarpaper is then installed. This is attached with roofing nails and/or hot tar. This paper underlayment plays an important role in protecting the surface of your roof. After the first layer has been attached, a second layer must also be installed for maximum benefit.
Add Sheet Metal Items
The next step involves installing all metal materials such as guttering, flashings, and drip edges. Install the gutters first, then the drip edges, which provide a way to divert rainwater off the roof of the house. This and the other sheet metal pieces also prevent rain from collecting in the seams and working its way through the shingles and into your house.
The Outer and Final Layer
The final step in installing a roof is attaching the outer layer of roofing material, whatever type you have selected. This creates the last layer of protection of your roof from the elements and after you have completed this, you should be ready for just about anything, with the exception of something like a hurricane or a tornado. Just keep in mind the importance of what materials you have chosen, and you should have a roof to last for years to come.
