Roof Repair vs. Replacement

Whether you need an emergency repair or a complete roof replacement, we can take care of your roof with the quality and professionalism you deserve. However, it can sometimes be tricky to tell if you need a simple repair or a complete overhaul. If your roof is close to 20 years old, it is most likely best to replace it. Most builder grade roofs have 20-year warranties, and after this time passes, leaks, holes, and missing shingles may become common. Also, if you are noticing moisture damage to your roof deck, then a simple fix will not resolve the issue. The shingles have to be torn off, and the deck will need to be replaced. On the other hand, if your roof is relatively new and there’s just a small damaged area, a repair should suffice. Our trained staff can give you advice you can trust regarding repairs versus a replacement.

Understanding Sloping in Roofs

If you consider the overall shape of a roof, most roofs have a slope, which is measured in inches of rise over inches of horizontal run. A roof with a 4-in-12 slope rises four inches for every foot of horizontal distance. Near the middle of your roof, there may be a ridge, which is the top edge of two intersecting, sloping roof surfaces.

As with a landscape, an intersection of two downward-sloping roof surfaces is called a valley. If the roof inclines over a wall, that edge is referred to as a rake. The small structure projecting from a sloped roof, usually a window, is a dormer. Anything else pushing up—such as vents, pipes, stacks, or chimneys—are penetrations. Any penetration or intersection is an opportunity for water seepage. Little pieces of metal called flashing help prevent leaks in these areas.

What Does Edging Entail?

Along the outer edges of a roof, there is often an L-shaped strip, usually metal, called a "drip edge." This allows the water to drip clear of the deck, eaves, and siding. The eaves are the lower horizontal edge of a sloped roof. Slated devices called louvers ventilate the space below a roof deck and equalize air temperature and moisture. Walls and roof systems use a vapor retarder to restrict the passage of water vapor. A flat board, band, or face at the cornice's outer edge is a fascia.

Framework of a Roof

As for the overall structure, rafters are the supporting frameworks for a roof. However, many modern homes and buildings also use trusses, which are engineered to supplement rafters. Trusses are so essential to the durability of the individual structure that they can't be cut or altered. The deck, or sheathing, is the plywood, or oriented strand board (OSB), to which roofing materials are applied. OSB comes in 4x8 panels made of narrow strips of wood that have been crisscrossed in layers and glued with resin. An outer layer of asphalt-saturated material called felt, underlayment, or tarpaper protects the roof deck.

How to Measure the Size of Your Roof

When you talk about the size of a roof, the unit of measure used is often called squares, which represent 100 square feet. When you compare materials, consider the fire rating, which can be class A, B, or C. Class A materials are the most resistant to fire originating from outside the structure.
