Sorry Calvin but I guess I wasn't really clear about the roofing material--we think tiles were original to the house when it was built since tiles are still present on the garage roof--but a previous owner put a new cheap, poorly installed, shingle roof on the house (estimated to be ~7 years old but the inspector) which now needs to be replaced.
We want to go with a high end shingle (50 yr warranty with great aesthetics as well!) that will carry us through our intended stay at the house and not leave us needing to put a new roof on the house again during our lifetime there and wondered if it then made sense to get high end gutters as well. If we get aluminum gutters and they have to be replaced in 20 years, the installation could compromise the warranty on the roof if shingles need to be taken off to put up new aluminum gutters. Does any of this make sense? or are we making a bad investment and digging ourselves into a deep costly hole??
I'm confused. If the house originally had what had to be a heavy tile roof, then the roof joisting system should be designed to take that kind of weight. If the "shingles" you keep referring to are composition roofing, why would you do that? Why not put on any of the new designs in many different materials there are.
Composition scars easily when hot, is subject to mildew and moss, and is enviromentally unfriendly as are not usually recyclable, so have about the worst enviromental track record. Also, asphalt shingles have a low insulative value and a shorter lifespan than many other roofing materials available today.
Metal roofs can look like darn near anything from cedar shingles, to slate. Is durable to a long life span of
at least 50 years. Low maintenance. Has excellent performance in high wind, hail, and rain. Is enviromentally friendly, and strongly resists fire with a class A fire rating.
There are now pressure treated wood shakes that can resist fire and can last 30 to 50 years if maintained.
Reinforced concrete fiber that meets many of the more restrictive fire codes, because most are fireproof. Low maintenance. Extremely durable. Resource efficient. Many colors and styles including shakes, tile, and stone. 50 years and beyond. Possibly avoid in areas of many freeze-thaw cycles each year.
Engineered rubber / plastic that is very long lasting 30 to 50 years. Cost effective, attractive, large range of styles and colors. All made of reclaimed materials.
Composite Slate looks promising as well.
