Frequently asked questions..



When it rains is a metal roof noisy inside my home?

NO. Contrary to popular beliefs, metal roofing is very often quieter than an asphalt shingle roof. This is due to the fact that metal roofs float over the roofing deck creating an air space between the metal roof and the roofing deck. This extra space creates a sound barrier, so to speak.  The underlay coating used by London Eco-Roof Manufacturing Inc. provides additional noise reduction properties.

How long will a metal roof last?

A properly installed metal roof will last you a lifetime. Superior technology finishes provide long-term protection against peeling, blistering and curling. There is an option of restoring and recoating the finish in 40 or 50 years' time in order to extend the longevity of the metal roof.

How much do metal roofs cost compared to asphalt?

The upfront cost of a metal roof is slightly higher than that of an asphalt shingle roof. However, a metal roof is a long time investment as it will outlast several asphalt roofs. That is why metal roofs will always cost less in the long run since the homeowner will save the additional costs of replacing several asphalt roofs. London Eco-Roof Manufacturing Inc. directly manufactures and installs its products.  A solid sheathing roof is the most affordable roof on the market in comparison to other metal roof products.

Are there standard ventilation requirements?

Proper ventilation is one of, if not the most important key factors in the life expectancy of a roof.  Depending on the type of the roof and its slope, asphalt roof requirements can range from 1sq. ft. of ventilation for every 300 sq. ft. up to 1 sq. ft of ventilation for every 150 sq. ft. For example,
1000 sq ft roof require 3 to 7 vents
1500 sq ft roof require 5 to 10 vents
2000 sq ft roof require 7 to 14 vents
