When dealing with the roof in your home, make sure that you determine the time to re-shingle them. Although some roof experts will tell you that you should replace the shingles at the first sign of wear, others will advice you to wait until they are starting to break apart or shrink.
Nonetheless, the best method to find out is to do a visual check on every row of shingles and inspect them carefully. Immediate attention is required because the roof is the lifeline of your home structure. This is especially true when the shingles begin to fall apart even with the minimal pressure applied towards it.
Check the shingles for wave like formation, ripple along the rows, and inspect tabs for any adhesive failure or dull spots. A loose grit on the surface, on roof jacks and step flashing is an indication of shingle decay. Be extra careful with loose grit that feels like sand when you step on it to prevent slipping and falling.
Asphalt roof singles have a life span of ten to thirty years when exposed to several elements. Shingles constantly exposed to sunlight will fade in color and deteriorate faster than those who receive less sunlight.
In re-shingling your roof, you need the following materials: nail gun, chalk, boards, shingles, feathering strips, 15 lb. felt paper and starter strips.
Steps in re-shingling:
Repair or replace damaged roof structure or rotting boards by removing or driving down protruding nails. If you want to apply new shingles over the old ones, secure the old shingles with the use of a nail guan and smoothen the look with the use of feathering strips.
Lay down the fifteen-pound roofing over old shingles and waterproof the roof through overlapping each felt by two inches. The felt should be stapled to the roof structure. Start from the edge eaves and extend upwards toward the roof ridge.
Establish a starter strip at the bottom of the roof. The starter strip must protrude over the eaves and the gable by five to eight inches.
Find the center of the roof and mark it with the chalk. Aim the first shingle on the chalk line and it should be directly p laced above the starter strip. Use the nail gun to secure the shingle in place.
You can now lay down the first course of shingles. Starting from the bottom of the shingle, measure from 5 to 5/8” upwards. This is where the nails should be place. Drive four nails in a straight line from one edge of the shingle to the next to secure it.
Continue laying down the first course of shingles until you have secured each successfully in both directions, and then begin the next course. Use the chalk to help in the application of the shingles. Make a line at least five inches based on the instructions of the manufacturer to ensure that the line is straight. Continue this process until you reach the ridge of the roof.
Proceed with the process until you have finished one side of the roof. Use the same method when doing the other side of the roof.
