Whether a metal or shingle roof is better for you depends on your preferences. Standing seam metal roofs require little to no maintenance, but if you install a screw-down metal roof where the fasteners are exposed, the gaskets on the fasteners will dry rot and need to be replaced. Generally, screw-down metal roofs need to be re-screwed every 15 to 20 years.

Metal roofs are energy-efficient and have extended warranties, while asphalt shingles are less durable than most. They tend to lose color and get damaged over time, and absorb heat from the sun.

There are several signs that indicate you’ll need new underlayment. Clear signs include missing or damaged roofing and exposing the underlayment to the elements. Additionally, if you notice water damage in your home by the roof after a storm, it could indicate that your underlayment may need to be replaced. If your gutters aren’t draining properly, it could also lead to rotting or water damage to the underlayment.

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.

Before hiring a roofing contractor, it's wise to ask several key questions. Inquire if they are licensed for roof replacement and repair and if they hold any special certifications. Ask if they will be completing all the work themselves or subcontracting parts of it. It's also important to understand the project timeline, whether they will remove the old roof or place new shingles on top, and how they will handle cleanup after the project is complete. Finally, ask about warranties for both work and materials, what recourse you have if issues like leaks arise, and if they can provide customer references.
