What affects the cost of a roof replacement? Size is a major factor. Of course, large roofs cost more to replace than small ones. Material is another obvious answer. Tile or metal is going to cost you more than shingles. These are definitely two of the biggest factors that impact how much a company will quote you to replace your roof. But they are not the only factors that weigh in. The following are some lesser-known elements that affect a roof replacement quote.

How many valleys does the roof have?

Some roofs have one peak and zero valleys. If your home shape allows for it, then your roof may have two peaks and one valley. Or, if you have a really large home with multiple wings, you might have three, four, or even more valleys. The more valleys you have, the higher your roofing quotes are likely to be. It takes roofers longer to apply shingles or other roofing materials to multiple slopes. Plus, they need to put down metal flashing in each valley to prevent leaks, and the more valleys there are, the more time and materials it takes to do this part.

Does your roof need any deck work?

The roof deck is the wood that forms the structural base of the roof. It's not usually replaced when your roof is replaced. However, if parts of the roof deck are cracked, rotting, or otherwise in poor shape, your roofer may need to replace those sections. This adds time and materials to the scope of the job, which means your roof quotes will be higher when roof decking work is needed.

How hard is your home's roof to access?

Is your home in an open field where the roofers can bring their trucks and dumpsters straight back to it? Or is your home in the city, sandwiched between two other homes, with little space for the roofers to work? How easy your home is to access will impact your roofing quote. Roofers will charge you more if they have to park a block away, rent a specialized dumpster, carry the loose shingles down the road, or so forth.

With this information in hand, you should have a better understanding of where your roofer is coming from when they give you a quote for roof replacement. The more deck work they need to do, the more valleys you have, and the harder your home is to access, the more you can expect to pay.
