What You Need to Know Before Accepting a Roofing Bid


The quality of a building’s roof can impact its climate control, its readiness for adverse weather conditions, and even its real estate value. With so much on the line, commercial building owners need a roofing company they can trust to perform quality work for a reasonable price.

For most building owners, the first step in selecting a roofer is receiving multiple bids, but correctly evaluating the bids can be challenging. If you will soon receive bids for a commercial roofing job, below are six things you should know about each bid before you consider accepting it:

Is the Bid Amount Within the Expected Price Range?

Everyone knows not to accept an unreasonably high bid, but not accepting an unreasonably low bid is also wise. Contractors who underbid for their services often have a good reason for doing so, such as a lack of licensure, a lack of experience, or a spotty work history. You should always look for an affordable offer, but accepting a low bid at the risk of poor workmanship is a bad financial decision.

Is the Bid Final or Subject to Change?

Some roofing contractors make an affordable bid to get the job, and then increase the price when the work commences. To avoid being a victim of this bait and switch tactic, have the contractor sign an agreement stating the bid is final.

Does the Bid Include all Supplies and Services?

The roofing bids of some contractors include the cost of labor and major supplies, but not the cost of minor supplies such as nails and caulking, or side services such as waste removal. Depending on the scope of the work, the cost of these supplies can add up to a meaningful sum. To avoid being surprised by the final bill, ask a contractor to include the price of all supplies and services in its bid.

Will all Materials have a Manufacturer’s Warranty?

New roofing materials come with a manufacturer’s warranty, but some contractors use materials from previous projects-a fact they would never tell you. To ensure your roof receives new materials, ask the contractor to provide receipts for all materials purchased. If the contractor seems unwilling to do this, it may be planning to use already purchased materials while charging you for new materials.

Will the Workmanship have a Contractor’s Warranty?

Reputable contractors stand behind their workmanship by providing a contractor’s warranty. If your roof is improperly installed, this warranty requires the contractor to repair the problem at no cost to you. A skilled contractor has no reason not to provide a warranty for its work, so insist on receiving one.


Choosing the right bid for a commercial roofing job involves more than price consideration; it also involves investigating the nature of a bid, understanding its exact terms, and discovering whether the roofer is willing to work on your terms.

The tips above can help you to evaluate roofing bids from roofing contractors. For a list of licensed contractors in your area, contact the state’s Construction Industry Licensing Board.
