Custom Metal Roofs
There is only one word that adequately sums up our metal roofs: CUSTOM. Using our cutting-edge Standing Seam Roll Forming, each of our roofs is individually produced to order.
​
The roof is constructed using precisely cut and sized pieces. We have the most modern machinery and technology, allowing us to extrude your roof right at the construction site so that it can be roofed there and then.
​
For your home, we use a 26-22-gauge snap lock hidden screw metal-panel roof system that we specifically size on the job. The customer can choose from a wide range of colors for these metal panels to match their color scheme.
​
Like with all of our replacement roofs, we document the old roof's removal with photos or videos. Nowadays, more strict nailing regulations and patterns are used to re-nail all existing decking.
Common Metal Roofing Myths in Portland, Oregon
MYTH #1:
Metal Roofs are more likely to get struck by lightning.
Answer: This is false. Lightning is attracted to the tallest structure. A metal roof is no more likely to get struck with lightning than a composition roof. A metal roof however, is non-combustable and would evenly disperse the energy. There is far less chance of fire with a metal roof.
MYTH #3:
Metal roofs rust and corrode.
Answer: Metal roofs are galvanized and have alloy coatings in the finish that will protect the roof from rust and corrosion for the lifetime of the roof.
MYTH #5:
Metal roofs cost more than a composition roof.
Answer: In the short term, the cost of a metal roof is higher than composition roofing. However, a metal roof will outlast a composition roof by 3 to 4 lifetimes and, metal roofs add to the energy efficiency of your home, lowering energy bills by an average of 20% to 25%. In the long term, a metal roof is considerably less expensive than composition.
MYTH #2:
Metal roofs are heavy and will add weight to my structure.
Answer: Metal roofs are 50% to 75% lighter than other roofing materials, more durable and have a much longer lifespan.
MYTH #4:
Metal roofs are louder than their counterparts.
Answer: Metal roofs are installed over a solid deck and a thick underlayment. Most often aluminum roofing can be installed over an existing composition shingle, adding to noise reduction.
MYTH #6:
A metal roof will affect the resale value of a home.
Answer: This is TRUE. A metal roof will increase the resale value of a home with its durability, appearance, and quality.
