Guide to Roof Age, Style, & Choices of Roofing Materials
Determinng the Age of a Building
- ROOFING MATERIALS, Age, Types - CONTENTS: This building roof architectural style & materials photo guide and text help determine the age of a building roofing materials & styles. Building component age: construction materials, methods, including hardware, saw cuts, and other details can help determine when a building was constructed or when it was modified.
- POST a QUESTION or READ FAQs 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
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.
History and Dates of Use of Various Roofing Materials
This article explains the eras of use of different types of roofing materials as an aid to understanding the history and age of buildings
If you are trying to determine the age and condition of a particular roof covering, please
see AGE OF ROOFING.

Cement Board & Fiber Cement Roofing Products
Exterior Siding & Roofing Using Asbestos Cement included asbestos cement shingles, asbestos cement siding, corrugated asbestos-cement roofing.
Other fiber cement materials used in construction included
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, at page left, and at More Reading at the end of this article.
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
- NAILS & HARDWARE, AGE 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 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.
