To install architectural roofing shingles, you need to prep your roof, lay down underlayment, nail the shingles in rows, and seal all the edges. Architectural shingles are thicker than basic shingles and last much longer. According to RubyHome, architectural asphalt shingles cost between $4.50 and $8.25 per square foot. These shingles can last about 30 years if installed the right way. Many homeowners choose them because they look nicer and hold up better in bad weather.

What Do You Need Before Starting?

Start by checking your roof for damage and rot. You need a clean, flat surface to work on. Pull off old shingles if this is a replacement job.

Get these tools ready: a hammer, a nail gun, a tape measure, a utility knife, and safety gear like gloves and a harness. You also need roofing nails, underlayment, and flashing materials.

How Do You Lay Down the Base?

First, roll out the underlayment across your entire roof. This layer stops water from leaking through. Nail it down every 12 inches to keep it tight.

Next, install flashing around chimneys, vents, and edges. Flashing is metal that directs water away from weak spots. According to industry data, poor flashing is a top cause of roof leaks, so don’t skip this step.

How Do You Nail Down the Shingles?

Start at the bottom of the roof and work your way up. Snap chalk lines to keep rows straight. Peel back the adhesive strip on each shingle and press it down firmly.

Nail four nails per shingle, about 5.5 inches from the bottom. Place nails in the slots between tabs. Don’t hammer too hard or you’ll split the shingle. According to RubyHome, most architectural shingles are installed at $4 to $40 per square foot depending on labor costs in your area.

Overlap each new row over the row below by about 5 inches. This overlap keeps rain out.

What About Sealing and Finishing?

Apply roof cement under the tabs of each shingle in hot climates. This bonds them together. In cold areas, the sun’s heat will seal them naturally over time.

Check all seams and edges for gaps. Seal any cracks with roofing cement. According to RubyHome data, architectural shingles last about 30 years on average, making them a smart choice for homeowners.
