Installation Process
Proper installation is key to ensuring the longevity and performance of asphalt shingles. Here are the main steps involved:
Preparing the Roof Deck – Ensure the roof deck is clean, dry, and properly sheathed to provide a solid foundation for the shingles.
Installing Underlayment – A waterproof underlayment is placed over the roof deck to add an extra layer of protection against moisture.
Adding Starter Shingles – These are installed along the eaves to prevent wind uplift and water infiltration.
Laying the Shingles – Shingles are installed in overlapping rows, starting from the bottom and moving upwards to ensure proper water runoff.
Sealing and Flashing – Flashing is installed around roof penetrations like chimneys and vents to prevent leaks.
Final Inspection – The completed roof is inspected for any gaps, loose shingles, or potential problem areas to ensure a secure installation.
Maintenance Tips for Asphalt Shingles
Regular Inspections – Check your roof at least twice a year and after major storms to identify any damage.
Clean Debris – Remove leaves, branches, and other debris that can trap moisture and lead to damage.
Address Moss and Algae Growth – Use a gentle cleaning solution or zinc strips to prevent moss and algae buildup.
Repair Damage Promptly – Replace missing or damaged shingles as soon as possible to prevent leaks and further damage.
