Anatomy of a Roof

Major Components of a Roof

Roof Diagram

A low-slope or flat roof covered with alternating layers of roofing felt and hot-mopped asphalt and topped off with a layer of gravel.

The wood or metal finishing at ends or edges of building, including a fascia, frieze, or rake.

The flashing that is embedded, or attached, and sealed at its top in a wall or other vertical structure and is lapped down over base flashing. Courses Horizontal rows of shingles or tiles.

The strip of metal extending out beyond the eaves or rakes to prevent rainwater from curling around the shingles back into the wooden portion of the house.

The lower edge of a roof (often overhanging beyond the edge of the house).

A 3-foot wide rubber membrane adhered to the sheathing at the roof’s edge that attempts to stop migrating water from entering your home during severe ice dams.

A synthetic rubber membrane (ethylene propylene diene monomer), used on low-slope and flat roofs.

A decorative board extending down from the roof edge either at the eave or at the rake.

The bituminous paper used by roofers, usually made of a combination of asphalt and either paper or rags.

Sheet metal or other material used at various planes on a roof to prevent water leakage.

A board at the top of the house’s finished wall, forming a corner with the soffit.

A laced valley, or woven valley, is a continuous run of shingles where two sloping roofs meet.

The number of inches of vertical rise in a roof per 12-inches of horizontal distance.

Structural wood, usually slanted, to which sheathing is attached.

The slanting edge of a gable roof at the end wall of the house.

The horizontal line at the top edge of two sloping roof planes.

Boards or sheet material that are nailed to the rafters to which shingles or other outside roofing materials are secured.

Flashing that is laid in strips under each shingle and bent up at the edge of a chimney or wall.

The area that encloses the underside of that portion of the roof that extends out beyond the sidewalls of the house.

One hundred square feet of roof or the amount of roofing material needed to cover 100 square feet when properly applied.

The material (usually roofing felt) laid on top of sheathing before shingles are applied.

Where two sloping roof sections come together. Shingles in the valley are cut in a “V” direction exposing the valley flashing fabric.

Excellent service. Any question I had was addressed in a friendly yet professional manner. I have used Pond before for replacement windows and siding and most recently for new roofing. I highly recommend them for their responsiveness and the high quality of their work.

Nancy P.

Easy communication with tons of photos and excellent job! Pond Roofing even came back to replace the color of the shingles to our satisfaction. The property was in McLean and they made me look great since my landlord client was very impressed. The swag cookies to our tenants was an added bonus. :-) Thanks so much!

Laura M.

Very fast initial response time and great customer service. Repair work was done (by prearrangement) while we had to be out of town and it looks great now that we are back. We have used Pond before and would call them first if we need roofing work in the future. Thanks!

Scott C.

Great communication, very professional repair crew. We have a new construction house that had some issues with vent seals after 10yrs and Pond fixed 8 different areas in one day--very happy with the work.

Ryan H.

I recently hired Pond Roofing to check out a leak. They did a great job coming in on time and to troubleshoot the issue. Their pricing was competitive and overall service was excellent. I’m very happy with their work.

Hassan W.

Pond Roofing was very responsive and knowledgeable about the condition of our roof. They delivered before the expected date and their work was impeccable. I cannot recommend working with Shanti enough.

Erin M.
