 Signs That You Need to Replace Your Asphalt Shingles

Replacing your roof can be costly, but it may be necessary. Here are some signs to look out for.

• Cracked tiles: Cracked tiles can be replaced, but waiting to do so can lead to long-term damage. Many cracked tiles may be a sign that your roof is getting old.
• Discoloration: Discoloration on your roof tiles may signify algae buildup. Left unmanaged, algae can eat away at your roof and cause severe damage.
• Interior staining: Staining on your home’s interior ceiling can signify a leaking roof. It’s best to investigate this quickly, as holding off could cause more damage.
• Water seeping: Water can seep underneath improperly installed tiles. Noticing this may indicate that your roof is old or was installed improperly and requires replacement.

Replacing asphalt shingles can be a time-consuming and challenging task, but it is essential to maintain the integrity of your roof. 

Here are the steps to replace asphalt shingles:
 

1. Safety First: Start by ensuring that you have all the necessary safety gear, such as a hard hat, gloves, and slip-resistant shoes. Also, make sure that you have a sturdy ladder to access the roof.

2. Remove the old shingles: Using a roofing shovel, remove the old shingles, starting from the top and working your way down to the bottom. Be careful not to damage the underlying roof deck or any flashing.

3. Inspect the roof deck: Once all the shingles have been removed, inspect the roof deck for any signs of damage or rot. If any damage is detected, repair or replace the damaged area before installing the new shingles.

4. Install the underlayment: Lay the underlayment over the roof deck, starting at the bottom and working your way up. Ensure that the underlayment covers the entire roof deck and overlaps at the seams.

5. Install new shingles: Starting at the bottom of the roof, install the new shingles, making sure to follow the manufacturer's instructions. Install each shingle with roofing nails, placing them in the designated nail line.

6. Install flashing: Install flashing around any chimneys, vents, or other protrusions on the roof.

7. Clean up: Once all the new shingles have been installed, clean up the job site, removing any debris or waste materials.

It is recommended that you hire a professional roofing contractor to replace asphalt shingles if you do not have experience working on a roof. This will ensure that the job is done safely and efficiently.
