Our new Interlock aluminum-shingle roof was installed last fall. It looks great, and has exceeded our expectations in terms of appearance and function. The installation was completed quickly, by careful and courteous installers, with minimal mess and disruption.
A few specifics to mention - when the snow slides off the roof there is a rumble like an avalanche just before it begins to give way, (after the first few times you get used to it) and then a curtain of snow and ice heavily thunder down into a line of piled snow a few feet away from the house resembling a barricade. Snow guards are essential! Plus, if you have a patio, deck, garden, and/or decorative landscaping next to your house, ensure all ornamentation, furniture, and moveable fixtures are either removed for the winter or placed in an area that will not be affected by the avalanche of snow.
We have not detected any increased noise from rain, and in fact, because the aluminum shingles are installed directly over the asphalt shingles, the sound may even be muffled.
We have noticed that our heating bills this past winter have been lower than previous years. There may be a number of factors, but we suspect that one is our Interlock aluminum shingles. We look forward to this summer to see if our cooling bills will be decreased.
If you are looking to replace your asphalt shingles, we would highly recommend choosing Interlock!
