How Are Asphalt Shingles Installed


Asphalt roof shingles are the most popular material used for roof construction. It is one of the least expensive roofing materials and available in a wide variety. This material is easy to install and can be recycled. Asphalt shingles also help treat mold and mildew.

In this article, we will discuss how to install asphalt shingles on your roof.

Get Roofing Assessment

While installing asphalt roofing shingles, the first thing we need to do is to hire a contractor to make measurements. The contractor will help you find the right amount of shingles for the project and measure the length and width of each section of the roof to estimate the area.

After getting an estimate about the area that needs to be covered, buy the underlayment and shingles.

Remove Old Shingles and Clean the Roof

Remove all the shingles and flashing with the help of a roofing shovel. Use the hammer method to get them off and make sure to protect the sides of the house and windows while removing the shingles. Detaching shingles safely should be the priority, as we can break them while removing.

After removing the shingles, the roof becomes dusty. Sweep it and make it as clean as possible and remove any lingering nails. There may be unattached or rotten boards in the sheathing—if so, then nail the un-attached boards on the roof and replace them if they are broken.

Install Underlayment and New Flashing

After cleaning the roof and detaching the broken boards, the next step is to install underlayment or waterproof membrane as a new flashing. Use staples to avoid the tearing of the membrane and attach them to the roof deck and continue the process for each row until the whole area gets covered.

Before installing the new asphalt roof shingles, fasten the drip edge to prevent water from penetrating within the roof. This extra layer is to protect the roof against excessive moisture.

Use the Starter Course and Chalk for Guidance

We can cut the asphalt shingles according to our project or we can also buy pre-cut shingles. Some people prefer pre-cut ones and adjust them to their roofing type, while others buy only one variety of shingles to fit.

Make a chalk guideline from the right to the left edge of the roof. We can use chalk to mark where the shingles would fall into place. Chalk lines are easily erasable and give clear marks on where to put shingles.

Place Asphalt Shingles on the Roof

The wind may affect the roofing material by generating uplift pressure. Lay the asphalt shingles and attach them using asphalt nails and a hammer. Use proper nailing technique and put four nails on each shingle. If the area is prone to high winds, then use six nails. Apply asphalt cement around the edges of the roof after fixing the shingles with nails.

Final Words

After installing asphalt roof shingles, we need to double-check the work and make sure the roof is properly installed. Keep a close eye on the work done over the next few months. Check if there is any leakage because even a little leak can damage the roof. If a single section allows water to seep into the roof it can cause serious problems.
