Roof Replacement

Asphalt roof shingles and flashing typically last between 20–25 years, depending on the materials used, quality of the installation, and weather conditions. Here are some questions to ask yourself when you consider your roof’s condition.

Are there obvious signs that repair or replacement is needed? Have you experienced water leaks or water damage in your attic? Do you have water stains or water marks on interior ceilings or walls? Does your roof have visible signs of buckling, decayed or broken shingles, or bumpiness?

How old is the roof? Has it outlived its life expectancy of 20–30 years? Is the attic properly vented? Is there algae growth, tree debris buildup, or rodent damage?

If you are uncertain if your roof has issues, or are unsure of the remedies available, GRT Roofing can provide an inspection to help you decide if a roof repair, or a full roof replacement, is the right choice for your circumstances.

Every job is different, but for most roof replacements, the process happens like this:

• Existing shingles are removed, along with old flashing and drip edging.
• Minor repairs are made as needed, including replacing rotten or bad plywood sheathing.
• Ice and water shield is installed where needed.
• Asphalt roofing paper applied over roof sheathing.
• Metal drip edging is installed around the edges of the roof.
• Flashing installed in roof valleys, where two roof planes meet (if needed).
• Shingles installed, starting at the bottom and working towards the roof ridge.
• Flashing installed along all vertical surfaces, like chimneys, skylights, etc.
• Roof ridge vent installed (if needed).
• Clean-up and haul away of debris.
