When it comes to roof replacement and repair, many factors can affect the final price of the entire project. If you know most of the details, such as the size and materials you are going to use to replace your roof, it is possible to use a roofing contractor. Roofing contractors are free and available to use online. However, in order to get proper homewise estimates in Maryland, you need to consult with qualified contractors who understand the home remodeling business and have a lot of experience in roof replacement and repairs. Before doing a roof replacement, you should learn which factors influence roof estimates the most.

Size and Complexity

The most important factor that will determine the cost of your project is the size of the roof. The size will determine how much material you need to buy and how long will it take to complete the job successfully. In order not to underestimate the total cost, you must measure every part of your roof precisely. This is especially important if you are working on a tight budget. The cost is calculated per roofing square. One roofing square equals hundred square feet. As you can see, the bigger the roof, the more you will have to spend to repair it or replace it.

The second essential factor you should have in mind is the complexity and pitch of your roof. The more complex and the steeper your roof is, more money you will have to spend. Increased steepness means your roofing contractors will have more work. Highly pitched roofs usually require additional equipment that will ensure the workers are safe and that the job is properly done.

Type of Material

As you can guess, the type of material you are going to use will significantly affect your final price. Your choice of materials may not only depend on your budget, but also on your roof design. For example, if your roof has a high pitch, you won’t be able to use heavy shingles such as asphalt and clay ones. For an average homeowner, asphalt shingles are the most affordable option, but steeper roofs can’t tolerate this material. If you aren’t sure what material will best suit your roofing repair, you should consult with a roofing expert. An expert will also give you better advice on the durability of the material related to your location. In particular environments, certain materials can last more than their average lifespan of 20 or 30 years.


As you know, underlayment is a very important part of your roofing system. This part of your roof adds more protection and stability to the entire construction and helps to keep the sustainability of the roof at an optimum level. Therefore, this part sometimes also has to be replaced. Your roofing contractor will help you choose the right option, such as going for organic or synthetic felt.

Geographical Location

Your materials should be chosen according to your surrounding environment. For example, if you live in an unstable weather area, you must choose materials that are sturdy enough to withstand frequent weather changes.
