Whether you need some damage fixed or require a full replacement, it's important to know the factors that affect the cost of your roof work. Every roof is different, so no two will cost the same.
1. Roof Style
The style of the roof can have a major impact on cost, particularly if you are replacing the entire roof. The steeper the slope, for example, the more difficult the work and the higher the cost. Roofs with multiple hips and valleys, typically referred to as complicated roofs, may also cost more simply because they require more time to complete. Low- to mid-slope gable end roofs with a single peak and no valleys tend to be the least expensive to repair or replace.
2. Material Choice
The type of shingles you choose can have a major impact on the overall cost. The cheapest variety of shingles are asphalt, which are also the most commonly used because they are attractive and durable. Metal roofs can also be a good value because they cost more additionally but tend to have a longer life and less maintenance — especially if you live in storm-prone areas. Clay and slate tiles are typically the most costly.
3. Sheathing Condition
The sheathing, sometimes called the cladding, is the plywood layer that lies beneath the shingles. It makes up the main structure of your roof. Sheathing can last decades and typically doesn't need to be replaced each time you get a new roof. Issues like water damage or punctures, such as from a falling branch, can mean that you need to replace the sheathing. This can add quite a bit to the final cost of the roof.
4. Roof Penetrations
Roof penetrations refer to items like chimneys, vent stacks, and skylights. The more of these you have, the more work that must go in to fit the roofing around the penetration and ensure that they are properly flashed and sealed against leaks. This extra work can naturally add to the overall cost of your project. Skylights, in particular, can be a challenge as they are naturally prone to leaks, so they require extra care.
5. Accessory Needs
Roof accessories include things like gutters, a moisture seal along the drip edge, zinc strips to prevent mold, or additional vents. Not every roof will need every accessory. The more of these accessories that you need to be installed or replaced with your new roof, the more costly the project.
