Will A Roof Over Last As Long

But you must take care to install shingles correctly so they lie flat.

Will a roof over last as long. Materials and workmanship as well as the weather elements in your location determine the lifespan of a roof. If conditions are right new shingles laid over old shingles can be just as attractive and durable as shingles laid on bare sheathing. Installation is easier than for a tear off job because you can use the existing shingles as guides for laying the new ones. Fiber cement can go up to 25 years and the thicker asphalt can give you about 30 years.

However there are premium brands that can serve you diligently for 50 years. When installed correctly a typical standing seam metal roof will last anywhere from 30 to 50 years. Premium metals such as stainless steel titanium zinc and copper can last well over 100 years. But unless the sheathing is extensively damaged or the structure can t support the weight of another layer of roofing a better solution is to apply a new layer of shingles right over the old one.

Cedar shake can also go for about three decades. Most homes have asphalt or composite shingle roofing which normally last about 20 years.
