FAQ's about ECO ROOF
1. What makes Eco Roof different to other metal roofs?
Eco roof is one of the only roll-form metal roofs in Ontario that is built on a double strapped sheathing ventilation deck. Also known as Above Sheathing Ventilation or 'ASV'. This unique roof design involves installing both vertical and horizontal strapping over the existing roof sheathing that keeps you home cooler in Summer and Warmer in Winter and helps prevent Ice Dams
2. Can you guarantee that no ice-dams will happen during the life of the roof?
The likelihood of ice dams is greatly reduced with sheathing ventilated metal roofing systems and this is a well documented fact . Can we guarantee absolutely no ice damming?. No we can not. The main reason is that some roofs have serious underlying problems like 'heat traps' caused by too much insulation or bad design which prevents the roofs from ventilating properly
3. Does double strapping lead to condensation forming beneath metal panels?
Great question. A double strapped roof has vertical straps applied to the rafters over your sheathing deck, as well as horizontal straps. The main reason that a single strapped roof creates a condensation trap because it is not double strapped. A single strapped roof only has horizontal straps that will trap the moisture that forms beneath all metal panels and provides no open drainage plane to facilitate proper ventilation and drainage to the eave of the roof. Trapped moisture will slowly rot out horizontal roof strapping and lead to ultimate roof failure.
Metal shingles also experience condensation build up beneath them whenever there is any attic heat loss in Winter. Attic heat loss causes a warming of the underside of the sheathing deck. This happens because its typically 20C in your home and minus 20C outside in Winter and attic heat loss causes condensation beneath the metal shingles. This condensation has nowhere to go and remains on the underside of the metal shingles till Spring when the heat returns and dissipates the condensation. This is why many metal shingle manufactureres specifically preclude rusting on the underside of their metal shingles due to "inadequate ventilation and insulation"
4. What type of timber do you use for the strapping?
Spruce is a Canadian softwood that has proven to be a highly effective as a stapping material for metal roofing. It provides excellent anchoring characteristics for fasteners because it is not prone to becoming brittle and cracking like many hardwoods. The spruce we use is untreated 1" x 2" FFS for the vertical strapping, and 1"x3" FFS for the horizontal strapping. It is not treated because it is not weather exposed. Our roofing system is double strapped with both vertical and horizontal battens to provide optimum sub-tile drainage and ventilation . Our vertical strapping is mechanically fastened to your existing roof sheathing and rafters using long shanked nails, and the horizontal strapping that supports our panels is similarly attached to this vertical stapping
5. Can the existing slope of the roof be increased some what with graduated strapping?
Technically yes. We would need to determine by how much you want to alter the roof slope gradient and then decide if that is the right solution
6. Do exposed fasteners increase the likelihood of water leakage?
London Eco Roof architectural panels ( Bingo, Bravo and Eco Tile are engineered with a unique tension release feature built in to the relief edges of every panel course providing both lineal and lateral expansion. This feature eliminates the traditional stress loads exerted on exposed mechanical fasteners when the metal roof panels expand and contract like our traditional T-18 panel. We circumvent this issue by limiting the panel lengths of T-18 panels to 12 feet in length
Our ‘permaseal’ fastener system uses a corrosion resistant galvanised steel 1.5” fastener designed to match the longevity of your roof panels. The fasteners have an encapsulated neoprene washer sealed beneath a cupped metal washer that protects the neoprene washer against direct UV exposure. Our screws are coated with the same paint as your metal roof to ensure no color variation between your roof and the screws. The key advantage of exposed fasteners is that they allow roof panels to be individually removed or replaced in the unlikely event that panels are ever damaged by falling debris like trees.
4. Is your estimate strictly for steel roofing only? What would the price be for a 26 or 28 gauge aluminum roof?
The price for our aluminum roofing is approximately is $1.00 per square foot more than steel. Our steel roofing is 25 gauge and aluminum in 26 gauge. Aluminum has higher corrosion resistance- but is also softer. If you have concerns about falling trees or hail, steel is stronger. Both products carry the same warranty
5. I have a cathedral ceiling. Is it possible to remove only few of the shingles so that more cellulose insulation can be blown in from outside?
If that is what your architect recommends- I then suggest you have an independent cellulose contractor do this for you. Bear in mind that you should not completely seal cathedral roofs. They do require an airspace to 'breath' and you may well cause a bigger problem doing this. Also bear in mind that double strapped metal roofing will help negate most of the ice damming issues you are currently experiencing
6. Is there any discount for seniors?
Yes we offer a $400 Seniors Discount on orders exceeding $10,000 before HST
7. Is there any provincial incentive for upgrading asphalt shingles to a metal roof due to energy efficiency, fire resistance and increased safety ?
There are currently no federal or provincial incentives available to homeowners to upgrade to a metal roof. Some insurers will offer you a discount because metal roofing is fire resistant and wind resistant up to 160km/hour. Also bear in mind that our metal roofing system will save you on your Summer cooling costs, typically $300-$400 a year
8. What is the warranty on Eco Roof?
Eco Roof comes with a 55 year product warranty and 50 year labor warranty covering material and labour separately. The warrnty is non-pro-rated and fully transferable if you decide to sell your home.
We offer a no nonsense, non pro-rated , fully transferable warranty with the lowest number of limitations ofany warranty in the industry.
9. Does your iron-clad warranty explicitly cover me against mould and fungus?
A sub-tile ventilated roof system with double stapping is specifically designed to ensure optimum drainage and ventilation. No roof system offers better protection. Notwithstanding, mould and fungus growth due to heat and moisture traps within the attic are specifically precluded in our TERMS AND CONDITIONS of sale.
10. Do you offer both steel and aluminum options of your roof system?
We offer all panel profiles in both steel and aluminum. Aluminum is $1.00 per sq ft more than steel.
Pro's of aluminum.....higher corrosion resistance, con's.....softer , you need to take more care when walking on your roof, and an aluminum roof is more prone to denting if hail stones exceed 40mm
11. Why are there no ventilation stacks on Eco Roofs?
Does the system ventilate the attic sufficiently by itself to not require these stacks?
Our roofs use dual ridge ventilation. Your roof attic vents via the new ridge vent we install, plus our metal roof panels are double strapped to provide 'above sheathing ventilation'. Dual ridge ventilation provides the most effective form of year round ventilation for Canadian climates
12. How does Eco-Roof prevents squirrels and critters from entering your attic?
· Our vent strip uses nylon matrix technology - guaranteed to last 50 years
· Lower-profile is almost invisible once installed
· Prevents rain, snow, and insect infiltration
· Relieves heat and moisture from the attic
13. Are there any times of the year that Eco Roof costs less to install less?
That depends entirely on prevailing company policy, Winter installs can sometimes be cheaper for walkable roofs - a NO HST promotion is always offered by London Eco Roof between December 1- March 31. This is a promotion the company runs during the winter months specifically for homes that are bungalows and have a low pitch that allows our installers to do winter installations.
We promote the deal by 'paying the HST'. We do however pay the tax on the quoted price. The opening line of all contracts negotiated at this seasonal discount will state "Winter Works - Install by March 31st". This notation allows our head office to record and apply a credit to your job from an allocated winter marketing promotion budget.
14. What are the colour options and are they all the same price ?
We have a variety of colors to choose from . I normally show clients our 3 panels options and 9 colors hen I come measure the roof.
Standard Colors – Black, Blue-Gray, Slate Gray, Burnished Slate, Brown Mocha, Chocolate Brown, TerraCotta, Colonial Red, Green.
Premium Colors – Copper, Antichado ( extra $1.00 /cents per sq. ft)
15. How long does it take to install an Eco Roof?
Typically 4-7 business days depending on the sixe of the roof
16. What is the average lead time to get an Eco Roof installed ?
Typically 4-6 weeks
17. Is your Comapany Insured and and are your Workes covered under WSIB Insurance?
London Eco who isntall the roofs carry $5 Million in liability Insuraance and all workers are protected by WSIB workplace insurance.
