If you need your roof replaced, then you may decide to try your hand at shingling on your own. Many homeowners find that they are very happy with a DIY roofing job. However, you should know that you are probably not going to be nearly as quick as a professional. To reduce leaking issues, you may want to think about working on your roof in sections. You can do this by adding shingles to your roof using a technique called racking. However, the technique can cause a few distinctive issues with your completed roof. Keep reading to learn about two potential problems and how they can be avoided while you complete your roofing job.
Curling In A Pattern
Many professional roofers will install shingles on an entire roof within a day or two, and they will secure shingles in rows. The technique that professionals use is called shingle racking. During this method, the roofers start on the bottom edge of the roof and work their way up to the peak. They place a single row of shingles and attach them from left to right with roofing nails. As the roofer moves up the roof, the shingles are layered over one another.
If you want to complete the shingling in small sections, then you may consider using the racking method yourself. As you place your shingles and offset the tab seams, you will notice that every other row of shingles is a bit shorter than the previous one. When you go back to place another small section of shingles, you will need to pull up the last shingle on each long row to place a shingle underneath. You may inadvertently create a fold in the shingle when you do this.
Folded or weakened shingles will start to curl as they age, and this can create a pattern of damage that forms lines in the roof. This is called pattern curling. You can prevent the damage by securing one less shingle in each row of shingles as you move upward. This creates a stair pattern on the side like a pyramid. Aptly named, the technique is called either stair racking or pyramid shingling. The pyramid pattern will allow you to layer your roofing materials without pulling up any shingles to secure your nails.
Shadowing And Color Inconsistencies
Shingles, like other types of building materials, will be created in product runs where the shingles are made and then packaged together. Each run will be slightly different in color. Sometimes, runs that are created several months or years apart will be an incredibly different shade of color, even though the shingles are made by the same manufacturer. There are a variety of reasons for this. The shingles may be a slightly different texture and pick up more or less pigment than other shingles. More or less of the granules on the shingles may make them look different, and the roofing materials may have been stored for long enough that colors have faded.
Shingle color inconsistencies will look apparent when shingles are secured in small sections. If you roof in sections, then a pattern may appear where different blocks of the roof are different colors, and this is sometimes called shadowing. This can be avoided by purchasing all of the roofing shingles you need at one time. Look at the packages of the shingles to find the lot or run number. If possible, make sure all the shingles are from the same run.
When you bring your shingles home, open up all the packages. Create piles on the ground that match the number of shingles in each package. Place one shingle from each of the containers into each pile and wrap each pile in cheap kraft or butcher paper. Put the piles of shingles in a dry and dark place and take one package of shingles as needed to complete your roofing job.
