Metal roofs are very durable, but because of storm damage, rust, or expansion and contraction of the metal, they occasionally need repair. 

If you have any paperwork on the original purchase of your roof, check it to see if the warranty will cover repairs.

If the damage is fairly large, you can replace an entire section of the roof. But don't jump into this as a do-it-yourselfer unless you have experience with working on this type of roofing. It is generally best to call a metal roofing specialist who is trained in working with your roofing material.

Here are some tips for general inspection, maintenance, and small repairs:

1) Look for loose nails. Pull and re-nail them.

2) Look for holes, rust patches, or other signs of deterioration.

Why we like it: • Quick and easy to install • Reinforced for strength • Works on metal roof, flashing, skylights

3) Seal up leaks. There are a couple of ways you can do this. One is to use urethane roof cement, which has better protection against ultraviolet rays than common asphalt or plastic roof cement. Smoothly spread it over the hole or damaged area, using a putty knife. Another option is to use a self-stick waterproof flashing membrane like the one shown at right. Both urethane roof cement and waterproof flashing membrane will deteriorate over time and need replacement.

4) If necessary, re-seal all seams and edges along the flashing using a urethane roofing cement.

5) Replace severely damaged flashing; for this, call a metal roofing repair specialist.
