Guide to Roof Age, Style, & Choices of Roofing Materials
Determinng the Age of a Building
- POST a QUESTION or COMMENT about how to estimate building age from its roofing architectural style and materials
Roof age & architectural style guide: Here we provide a photo guide and a series of detailed descriptive articles that offer guidance in determining the age of a building and its roof by examination of the choices of roofing materials as well as the building roof architectural style.
The age of a building or its individual components can sometimes be determined quite accurately by documentation, but when documents are not readily available, visual clues such as those available during a professional home inspection can still determine when a house was built by examining its components, building materials, even nails, fasteners, and types of saw cuts on lumber.

Roofing Materials as Indicators of Building Age
Wood shingle roofing has been in use for hundreds of years in the U.S. and Europe.
But an inspection of interior and exterior roofing details can indicate the probable age of a wood roof (which can last up to 40 years) as well as the roofing history of the building, the number and types of roofing layers, and related house-age-determination details.
The wood shingle roof shown in the photo below is on a building in Key West, Florida,
adjacent to the Hemingway house, viewed from the Key West tower. Notice the absence of lichens on the
wood shingles in the roof area below the metal-flashed rooftop tower?
We discuss here various roofing materials (Wood, slate, asphalt shingles (in several generations),
clay tile, metal roofing (several styles and generations), and how they assist in finding The age of a building below.

Modern Cement Board & Fiber Cement Products
Cement board is a non-structural building sheathing material which in its contemporary form is made from Portland cement covered with a reinforced fiberglass mesh fabric. Cement board is used as a tile backer or a backer board for stucco applications on buildings. Current producers include Custom Building Products (WonderBoard™) and US Gypsum (Durock™).
Panels made of a mixture of cement and wood fibers are produced for building siding by James Hardi (Hardi-panel and Cemplank™), and CertainTeed (Weatherboard™).
Clues to building age include
these examples which we expand and detail in text and articles below.
Visual clues pointed out by a home inspector or available to any careful building inspector can help indicate the age of a building.
In addition to examining the roofing material, a look at roof framing, lumber marks, even types of fasteners all can relate the roof age to the building age and give information about both. More examples of this approach to identifying building architectural style, roof style, roof age and building age are in these articles:
- Architectural style, decorations, trim, building components - our introductory material is
at ARCHITECTURE, STYLE, & BUILDING AGE.
For detailed guides, see the articles and text organized
at ARCHITECTURE & BUILDING COMPONENT ID
and see - NAILS, AGE & HISTORY Construction fasteners, nails, screws, the use of treenails or pegs in post and beam framing, and fasteners such as roofing nails and screws used, hardware: window and door hardware, hinges, doorknobs, door pulls, latches
- ROOFING MATERIALS, AGE, TYPES, asphalt shingles, stone roofs, slate roofs, tile roofs, wood shingle and shake roofs, built up roofing ("tar and gravel roofs"), modified bitumen roofs, EPDM and other membrane roof coverings
- SAW & AXE CUTS, TOOL MARKS, AGE, hand hewn adze marks or even the type of saw cut marks on framing lumber
Keep in mind that even when we can identify specific types of building materials and building methods, precise dating of the time of construction of a building remains difficult: old building materials were often re-used, so beams, siding, and other components may appear in a building built later than when the materials were first made.
Also, in the U.S. various states had machines for making cut nails, screws, and sawmills at different times. For example, New York State was industrialized earlier than some western or southern states, so machine-made nails appear earlier in New York than elsewhere.
Historic Roofing Materials & Roof Age
History and Dates of Use of Various Roofing Materials
Familiarity with roofing materials used on historic buildings and with the history of manufacture of roofing materials can help determine the age of a building as well as the more practical question of age of and remaining life of a roof.
This article series explains the eras of use of different types of roofing materials as an aid to understanding the history and age of buildings.
The oldest roofing materials, in use since prehistoric times were stone or stone slabs, and slate. From Roman times clay roof tiles were widely-used and remain in-use today as a durable roof material.
You will read in the Reynolds shingle patents below that when shifting from the more-rigid traditional roof shingles of wood and their heavier brothers slate, stone, or clay tiles to a lighter and more-flexible asphalt roof shingle, the inventors had to cope with the problems of wind-uplift and durability that could accompany a flexible roof covering.
Early History of Asphalt Roof Shingles & the H.M. Reynolds Shingle Company
Harry M. Reynolds was one of the early if not earliest producer of asphalt shingles in the U.S.
...
Image above: H.M. Reynolds Shingle Co., showing green colored asphalt shingle roof in a 1910 catalog, retrieved 2021/08/05, original source: https://archive.org/details/HMReynoldsShingleCo
H.M. Reynolds was established in Grand Rapids, Michigan, U.S., in 1868. The image below shows that the company's shngles were approved by the Board of Fire Underwriters (for fire resistance), and were available in red, green, and blue-black.
Remarkably the little advertising flyer shown above includes a note that this H.M. Reyolds paper and asphalt-shingle-sample brouchure could be folded together and blown-throug to play a tune or to make a noise like a parrot or rooster! The flyer's patent gives it an earliest-possible date of April 1909.
Above Harry M. Reynolds 1914 asphalt shingle patent for hexagonal shingle shapes; we added colors to illustrate the shingle side-lap pattern.
- Reynolds, Harry M. ROOFING SHINGLE [PDF] U.S. Patent 1,108,236, issued August 25, 1914.
This patent is for the company's invention of the widely-used hexagonal-shaped asphalt shingle that the patent described as:
The object of the invention is to provide a shingle of such shape and so secured that when laid upon a roof it will avoid the fore going objections and to this end the nails by which it is attached will be located nearer the loose edge of the shingle than is possible with the ordinary form, and also the exposed portions of the shingle provided with obtuse angles thus stiffening that portion and preventing warping of the same;
to provide shingles which will not form an opening between adjacent edges of the same and permit the weather to beat through the roof; to provide shingles which when laid will present a pleasing appearance,
and to provide the same with certain new and use ful features hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, ...
- Reynolds, Harry M. ROOFING SHINGLE [PDF] U.S. Patent 1,115,866, issued November 3, 1914. This is an interlocking shingle of a different pattern, as you may read in the PDF.
Excerpts:
My invention relates to improvements in roofing shingles, and more particularly to shingles made of a fabric composed mainly of felt and asphalt. Heretofore such shin gles have been made in the form of a rec tangular parallelogram and laid in Sub stantially the same manner as the ordinary wooden shingles, that is, side by side with the lower portion of each shingle exposed to the weather and with nothing to hold them down in place at the lower end, being secured only by fastenings, such as nails, driven through the same beneath the next course above.
Shingles so laid must necessarily be quite rigid in order to stay in place, the action of the weather and wind having a tendency to raise their lower corners which are held only by the rigidity of the shingle itself, consequently shingles of this kind are required to be made of con siderable thickness and rigidity and contain more material than would otherwise be nec essary to avoid this tendency.
The object of my invention is to provide such shingles with certain novel features and particularly with means whereby the lower edges or lower ends of the shingles will be securely held down.
My invention comprises shingles of substantially rectangular form provided with recesses or indentations in their sides near their lower edges, whereby when these shin gles are laid the edge of each adjacent shin gle is inserted in said notch or recess and the lower corner of the shingle having this recess extends beneath the adjacent shingle.
This secures the lower corners of each shingle in place and adequately prevents the same from warping up or being loosened by the wind and weather at the lower edge. - Dupont, Henry H. ROOFING [PDF] U.S. Patent 1,201,811, issued October 17, 1916.
Excerpt: This invention relates to a roofing con struction in which shingles made of plastic material are used in conjunction with a novel substructure to form an imitation of terra cotta tile roofing. - Herbert, Abraham. INTERLOCKING SHINGLE [PDF] U.S. Patent 1,410,867, issued March 28, 1922.
