FREQUENTLY ASKED QUESTIONS
Is a metal roof only for industrial buildings and warehouses?
The term "metal roofing" still conjures up images of tool sheds with rust-streaked galvanized roofs, rustic barns with weathered tin roofs, and brick and mortar industrial operations with clusters of buildings capped with heavy-duty steel. As a commercial investment, durability, strength, longevity, and low maintenance characteristics made metal roofing very cost-effective, but aesthetics hardly factored into the all-important ROI equation. The dominant "return on investment" factors that made metal roofing the material of choice for so many commercial/industrial buildings can now be applied for residential projects as well thanks to DECRA's innovative development of stone-coated steel roofing products, which introduced sophistication and style to the metal roofing sector.

Why is DECRA the original stone-coated steel roofing product?
An emulsion coating derived from road tar and stone chips was first developed by the Decraspray Company in wartime England to camouflage the reflective corrugated metal roofs of important storage buildings and protect them from German air raids. After the war, the DECRA coating had bonded so well that it was virtually unremovable from the underlying corrugated iron. The coated metal roofs were so well-preserved that many began to see the incredible potential for creating a new standard of durable roofing products. The original DECRA formula has been improved with an advanced acrylic base which has set the gold standard for durability and longevity since 1957.

Are metal roofs noisy?
This is one of the most frequently asked questions we hear from those considering the pros and cons of a metal roofing upgrade. Both homeowners and businesses have the same concerns about disruptive rain noise on metal roofs. DECRA stone-coated steel roofing profiles don’t require any extra soundproofing materials and are peacefully quiet in the rain thanks to the sound-absorbing cushion of granular stone coating.

Does a metal roof make my home hotter in the summer? What about in the winter?
No. There is airspace between the roof deck and a DECRA roof panel.
This airspace provides an insulating barrier to help resist solar heat flow thru a roof and into your home. In the winter, this insulating airspace can help diminish ice dam formation that can cause roof leaks.
Can I walk on a DECRA roof?
Absolutely. DECRA roofs are made of steel and designed to withstand the weight of people walking on them. The panels could be damaged, however, if walking carelessly on them. Please review the walking instructions here to avoid any damage.
Is a DECRA roof more expensive?
A DECRA roof offers more value for your money. With a minimum 50-year life expectancy, you would have to purchase and install 2-1/2 shingle roofs for the cost of one DECRA roof. Like most products you buy, "you get what you pay for." A DECRA roof offers more for your money. It’s no bargain to put two roofs on your house because the first one was "cheaper" and subsequently failed. DECRA’s aluminum-zinc alloy coated steel enhances the superior weathering and corrosion resistance of each roofing panel.

Do DECRA roofs use a non-oiled granule?
We use only 3M granules and they do have a small amount of mineral oil on them. However, the minuscule amount does not interfere with the adhesion of our basecoat and does not affect water run-off.

Is water run-off from a DECRA roof safe to drink or collect?
Yes, the water run-off from DECRA roofs meets the World Health Organization Standards testing. However, rainwater is variable across regions; atmospheric conditions should be considered in actual use. Water collected during the first or second rainfall after extended dry periods can be contaminated by dirt accumulation.
