Frequently Asked Questions
- Are you licensed and insured?
We are licensed by the state of California as a roofing contractor. Our insurance covers both workers compensation and liability.
- How long will a new roof installation take?
Time depends on the size and difficulty, but the average size roof will take 4 to 5 days.
- Will we need to move out of our home?
No. Interruption to normal daily activity is minimal.
- Should we paint or roof first?
If doing both, select the roof and paint color so to complement each other. More choices are available with paint than a roof, so carefully consider your roof color. It will be easier to choose a paint color to match a roof color than the other way around. If you choose to roof before you paint then be careful of overspray onto the surface of your new roof.
- Will a steel roof make my home hot?
No. While all roofing products will get hot, steel will dissipate heat quickly. Once the direct source of the heat (sun) is not shining directly onto the roofs surface, the steel will cool to ambient within minutes; whereas, most other materials take hours to cool. There are tests done that will conclude that steel is the most energy efficient roof to purchase for a residential structure. Often cited tests that answer this question are from the Florida Power and Light and The U.S. Department of Energy. Further explanation in Benefits of Steel section.
- Is a steel roof noisy?
No. Most steel roofs have a granular surface that deadens the sound of rain.
- Will a steel roof rust?
All roofing materials utilize steel for the critical flashing areas; such as, pipe flashing, roof to wall and valleys. The steel utilized for these flashing areas is galvanized (zinc and steel). If you are re roofing then notice that the current flashings (galvanized) are most likely in good working condition. These flashings are a good test as to the length of service that your new galvalume roof would work. Testing of galvanized vs. galvalume shows results that galvalume will last 2 to 4 times longer than galvanized. Most roofing manufactures now use as their base metal a steel product commonly called galvalume or zincalume. The process to make this type of steel gives protection to steel far beyond the old process of galvanized steel. The steel is wrapped with zinc and aluminum. These metals are what protect the steel from corroding. As a result, the steel roof will be the last roof that the structure will ever need.
- Is a steel roof fire safe?
Steel roofing is classified as noncombustible roofing material (class A). The time tested values that steel roofing has in external fire situations are the wind resistance, impact resistance and ember entry resistance. In many fire conflagrations, we have seen steel roofs save personal property and possibly lives.
- Is a steel roof lightweight?
Yes. Although there is no definition of what is or what is not a lightweight roof, the weight installed of steel roofing products is approximately 2 pounds per square foot. This compares in weight to a wood shake roof. As a reference point, the average roof size for a residential home is 3,000 square feet; therefore, if a home has a wood shake roof then the structure has been carrying on its walls and roof, 6,000 pounds for the life of the roof and/or home. When replacing the roof, then keeping the weight the same would be wise given that the structure is now stressed for this weight and any added weight could be dangerous in the event of an earthquake. As the National Information Service for Earthquake Engineering stated after studying damage to structures from an earthquake, “lessons from such damage are clearly to avoid the use of unnecessarily heavy roofs”. Options marketed as lightweight roofs include concrete. Marketed as a lightweight alternative, lightweight concrete will be marketed as total weight in the 6 to 7 pounds per square foot range; yet, this is only for the field pieces and not the plywood, felt and trim. To calculate the total weight of a lightweight concrete roof you must add approximately 3 pounds to the marketed weight. The installed weight becomes 9 to 10 pounds per square foot or up to 27,000 pounds on an average size roof. Just a thought ? if you had your home engineered by a licensed engineer to study the capabilities of installing a concrete roof, would this engineer look at the structure (foundation, walls and roof) or would just the roof framing be looked at? Ask yourself the question, do I want my home to carry the same weight capacity as it always has or should I load the roof up to 4 or 5 times the weight? Carry 100 pounds around and then displace the 100 pounds with 500 pounds. Do you feel the stress? So would your home. What then would happen in an earthquake when you have all this weight moving? As an educational consultant to Engineering and Earthquake facilities stated, “as someone who has spent considerable time helping others to understand how best to mitigate the effects of an earthquake on manmade structures, frankly, adding this amount of additional weight just didn?t make sense”!
