Installation step by step
- Permits and material delivery, scheduled around the weather.
- Tear-off of the old roof (on replacements) and deck inspection.
- Replacement of damaged decking and re-nailing of loose sheathing.
- Drip edge, underlayment, and ice-and-water barrier at valleys and penetrations where appropriate.
- New flashing at walls, chimneys, and vents; new pipe boots.
- Starter course, then shingles or metal panels installed to manufacturer specifications.
- Ridge cap and exhaust ventilation, final inspection, and cleanup with a magnetic nail sweep.
Details that separate good installs from bad ones
- Correct nail count and placement per the manufacturer's wind rating instructions.
- Balanced intake and exhaust ventilation for Texas heat.
- New flashing rather than reusing rusted or bent pieces.
- Following manufacturer requirements so the product warranty stays valid.
Warranties: product vs. workmanship
Manufacturer warranties cover material defects; workmanship warranties cover installation errors and come from the contractor. Get both in writing and ask how long the workmanship coverage lasts.

Frequently Asked Questions
How long does a new roof installation take?
Many single-family shingle installs take one to a few days; metal and complex roofs can take longer. Weather and decking repairs affect timing.
Do I need to be home during installation?
Usually not for the whole time, but be reachable for decisions such as decking replacement. Move vehicles and fragile items away from the house.
Will installation be noisy?
Yes. Tear-off and nailing are loud, and vibration can shake wall hangings, so take down fragile items beforehand.
