Replacing Roof Shingles

Replacing roof shingles is a hot, back-breaking, dirty job. Care must be observed when installing roof shingles. The pitch of the roof and the temperature can make roof shingle installation difficult for a do-it-yourselver. Before you start, you have to purchase the right style and color asphalt shingles.

Many books have been written about roof shingles, so it is unthinkable that I can fully address  all possible questions. But I am sure I can point you in the right direction so you have years of leak-free performance from the new high-quality roof shingles you will be purchasing.

Let's first get realistic about what is involved when installing roof shingles. It is dirty, back-breaking work. If the air temperature is above 70 F, then you will be hot up on the roof. As the air temperature approaches 90 F and above, it can become dangerously hot on the roof. Dehydration can make you fatigued, dizzy and more prone to cutting corners. On top of all of this, is the inherent danger of simply working up on a roof. Whether you intend to or not, you will obey the Law of Gravity, and it can be both painful and/or deadly.

There are many different styles, textures and colors in asphalt shingles. There are almost as many different levels of quality. The price per square (a square is enough material to cover 100 square feet) is an excellent barometer of quality. As the price goes up, so does the quality and the warranty. If you need help visualizing a color and texture, consider buying just one bundle of the roof shingles and lay them on the roof as if they were nailed. Then get down on the ground and look at them to see if you like the color and texture.

I urge you to purchase your roof shingles from a roofing wholesaler that sells roofing supplies to roofers. Visit these well-hidden businesses and talk with the manager. You can discover these oases of information by doing an Internet search or looking in the standby Yellow Pages under "Roofing Supplies". The manager or owner will give you a quick education on the levels of quality across the different shingles. It is best to visit these businesses in mid-morning or mid-afternoon when the roofers are at their job sites.

You can sometimes install a new asphalt roof on top of an existing one. There are building-code considerations, so always check with your local building department. Personally, I have discovered over the years that you get a better job if you strip off the existing roofing materials.

This is miserable work, even with the best tools. Read all of the written instructions you can get from the roof-shingle manufacturer. Instructions are often printed on the packs of shingles, but do additional research to locate photos or videos of roofing tips.

Keep in mind that a majority of roof leaks happen where the roof touches up against something that is not a roof. Examples are skylights, plumbing-vent pipes, exhaust fans, chimneys, walls that extend higher than roofs, etc. You need to expertly install flashings at these locations. Flashings are transitional roofing materials that connect roofs to things that are not a roof.

When you strip off the old roofing material, check the wood sheathing for damage. Be sure the wood is securely nailed to the rafters and there is no wood rot. Install heavy felt paper or a modern water membrane in place of traditional felt paper. Consider using the special membranes that stop water leaks caused by ice dams or wind-driven rain.

You can buy roof shingles that mimic slate or ones that look like wood cedar shakes. From a distance, they do a very good job of fooling the untrained eye. I have used the slate-look asphalt shingles on my Victorian Shed, and they really make it look fantastic.

If you live in a humid climate, be sure you consider buying roof shingles that contain copper in the colored ceramic granules. This copper is a natural biocide that kills the common roof algae that is responsible for the ugly black streaks you see on many residential roof shingles.

Top-quality roofers will install edge flashings as well as a base or sill flashings. These are very important pieces of metal that help keep water away from your wood roof sheathing. Attention to detail is very important when working with flashings. Discover how these work and you will have a roof that keeps you dry in all types of weather.
