Look for any damaged or rotten areas and repair them as necessary. This step is crucial for ensuring your new shingles have a solid foundation.

Gathering Materials and Tools For a successful roofing project, gather the following materials and tools:

Asphalt shingles (architectural or three-tab) Roofing nails Hammer or nail gun Roofing underlayment (tar paper or synthetic underlayment) Drip edge Tin snips Utility knife Tape measure Chalk line Ladder Safety gear (gloves, safety glasses, and harness) 2. Installing the Underlayment Laying the Underlayment is a secondary barrier against moisture. Start by laying the underlayment from the bottom edge of the roof, working your way up. Ensure each row overlaps the one below it by about two inches. Secure the underlayment with roofing nails or staples, ensuring it lies flat without any wrinkles.

Trimming the Underlayment: Use a utility knife to trim any excess underlayment at the edges. Be cautious while cutting to avoid damaging the material. This step ensures that the underlayment fits perfectly along the roof edges, providing maximum protection.

3. Installing the Drip Edge Attaching the Drip Edge The drip edge is a metal flashing that directs water away from the roof edges, preventing water damage. Install the drip edge along the eaves and rake edges of the roof. Start at the bottom edge, nailing it into place every few feet. Make sure the drip edge overlaps at the corners for continuous protection.

Cutting and Bending the Drip Edge Use tin snips to cut and bend the drip edge around corners. Carefully shape it to fit snugly against the roof edges and trim, ensuring no gaps. This precision helps prevent water infiltration and provides a clean, professional look.

4. Installing Starter Shingles Cutting Starter Shingles Starter shingles create a solid foundation for the first row of shingles. Cut the tabs off a row of three-tab shingles to create a starter strip. Ensure you have a straight edge on the starter shingles for a neat and even installation.

Placing the Starter Shingles Place the starter shingles along the bottom edge of the roof, ensuring they overhang the drip edge by about 1/4 inch. Nail them in place, ensuring they are straight and secure. This overhang helps guide water off the roof and into the gutters.

5. Laying the Asphalt Shingles First Row of Shingles Start laying the first row of asphalt shingles directly over the starter strip. Align the shingles with the roof’s edge and nail them in place. Use four nails per shingle, placed about 1 inch above the cutouts and 1 inch in from each end. For added durability, consider using six nails per shingle.

Staggering the Shingles To create a staggered pattern, cut 6 inches off the first shingle of the second row. Continue this pattern, cutting 12 inches off the first shingle of the third row, and so on. This staggered layout prevents water from seeping between the seams, enhancing the roof’s waterproofing.

Continuing Up the Roof Continue laying shingles row by row, following the staggered pattern. Ensure each shingle overlaps the one below it by about 5-6 inches. Use a chalk line to keep your rows straight, ensuring a professional finish.

6. Cutting and Fitting Shingles Trimming Shingles at the Edges When you reach the roof’s edges, you may need to trim shingles to fit. Use a utility knife to cut the shingles to size, ensuring a precise fit. Leave a small overhang, about 1/4 inch, to direct water away from the roof.

Working Around Roof Features For roof features like vents and chimneys, cut shingles to fit snugly around them. Use roofing cement to seal any gaps, ensuring a watertight seal. Properly sealing these areas prevents leaks and maintains the integrity of the roof.

7. Installing Ridge Cap Shingles Preparing Ridge Cap Shingles Ridge cap shingles cover the roof’s peak, protecting it from water infiltration. Cut shingles into individual caps, or use pre-made ridge cap shingles. Each cap should be about 12 inches wide.

Placing Ridge Cap Shingles Start at one end of the ridge and work your way to the other end. Place each cap shingle over the peak, ensuring it overlaps the previous one by about 5 inches. Nail each shingle on both sides, securing it firmly. For a cleaner look, use roofing nails that match the color of your shingles.

8. Final Touches Inspecting the Roof Once all shingles are in place, inspect the roof for any gaps, loose shingles, or protruding nails. Address any issues immediately to ensure a long-lasting, leak-free roof.

Cleaning Up After completing the roofing project, clean up any debris, stray nails, and unused materials. Proper cleanup ensures safety and maintains the aesthetic appeal of your property.
