How do metal roofs hold up to winds, even hurricanes?

Metal roofing is very wind resistant, and can withstand high winds up to 150 MPH! This alone will cover any wind damage a hurricane could produce. Metal roofs are even resistant to hail! Unlike shingles that are nailed on, metal roofs are put on with screws and are far more sturdy. No more shingle blow-offs!

Will metal roofing make my house warmer in the winter?

A metal roof will save you money on your energy bill. In the summer the reflective paint will reflect sunlight away from the roof, and in the winter it will help keep the heat inside.

Does my old roof or shingles need to me removed to install my new metal roof?

How does the cost of a metal roof compare to other roofs?

The cost of a metal roof is far greater than a traditional shingle roof, however, metal roofs have an advantage over shingle roofs. You would more likely replace a typical roof 3 times compared to a metal roof, and metal roofs do not crack, rot, flake, burn or blow off like shingles can. You could save up to 40% in energy cost each month on your utility bill over the years. This alone is well worth the cost of your metal roof!

Shingle Roofing

Why does my shingle roof look streaked?

If you are noticing dark streaks on your shingles, that is the result of a type of algae that lives off the moisture in the shingle. As bad as it may look, there is a simple fix for this situation. Use a pump sprayer with a mix of one-part bleach to two parts water, and spray down the area. Then use a garden hose to wash. Be aware of your plants and shrubs, bleach could kill them. DO NOT PRESSURE WASH. You could damage your roof.

What are the fire ratings of Asphalt shingles?
  • Class A Fire Rating – Shingles with the highest fire resistance are classified as Class A. These shingles will be effective against moderate fire exposures, are not readily flammable and will not cause fires to spread.
  • Class B Fire Rating – Shingles that offer moderate fire resistance are classified as Class B. These shingles are also not readily flammable, will not readily contribute to the spread of fire and are relatively effective against moderate fire exposure. The main difference is that the testing process is conducted on a smaller configuration.
  • Class C Fire Rating – Shingles that offer light fire resistance are classified as Class C. These shingles aren’t readily flammable, won’t readily spread fire and are effective against lighter fire exposures.
I have leaks, will I need to replace my entire roof?

Not necessarily. You may be experiencing leaks from flashing that may be loose or shingles that may be damaged. Either way, we can perform an inspection and determine the best route to correct your problem.
