Alcoa has engineered Brentwood siding to stay secure and provide long-lasting protection with little to no upkeep -- all at an affordable price. This panel features a full 1/2" projection, full-length return for higher wind load resistance and a full lock for greater stability.
If you install your roof over an existing roof, you are increasing the weight load on your rafters. This combined with an additional ice & snow load in the winter can become an accident waiting to happen. Your roof should ALWAYS be stripped to allow for proper inspection of your roof deck.
