Roof shingles can last 18 to 20 years in south Texas, protecting your home from outdoor elements. And when it’s time for a new roof installation by a professional team, like ours at Mammoth, the process can seem pretty simple.
Roofers don’t work quickly because the job is easy. They work fast because the longer a home has no solid roof the higher the risk is of internal damage and weather delays. Each home is different, so each project requires a custom workflow and safety measures. Below are some of the steps roofers train to follow when taught how to shingle a roof.
“To shingle” means “to lay out or arrange to overlap,” so it makes sense that roof shingles are installed using many different, overlapping layers to shed water downslope. When water collects in crevices, it can lead to rot. Once the old shingles are removed from the roof, various materials are laid on top of one another in a specific order to ensure all rain and ice melt run off the roof.
Preparing The Deck And Primary Layers
After removing the old shingles, the roof deck must be prepared and stabilized. This is done by replacing any rotted pieces with fresh wood, making sure the deck is smooth, dry and fastened to the roof trusses. For the new shingles to appear smooth and flat, the deck must also be clean, solid and flat.
The drip edge is the first material installed. It is placed to create a sharp edge on the roof and protect the lower edge of the deck by preventing water from wicking back up. Then, a self-sticking, ice and water protector is installed on the lower deck and over the drip edge. This adds an extra layer of water-shedding protection.
The roof underlayment is installed next. Whether the material is synthetic or asphalt-saturated felt, it is laid in horizontal rows over the entire deck, acting as backup protection underneath the shingles. Next, metal flashing is placed around attic vents, plumbing stacks, chimney stacks and any other joining or valleys in the roofing. These are the most common areas for roof leaks, and this corrosion-resistant metal provides an added layer of water-shedding material.
Laying Roof Shingles
Once all those invisible protective layers are set, it’s time to install the primary water-shedding layer — shingles! Beginning at the lower deck areas, starter shingles are nailed onto the edges of the deck and joints for wind resistance, followed by field shingles over the entire roof. Hip and ridge cap shingles are nailed down next in the peak areas of the roof, since field shingles cannot be bent. After all the shingles are installed, any exposed nail heads are covered and sealed with asphalt roof cement.
