Quotes and estimates for roofing projects can sometimes vary widely from roofer to roofer, which is why we've come up with this list of essential information to have with every quote.

A new roof applied with expert hands, using the highest quality products can last decades while a roof installed with bad workmanship and inferior quality materials can lead to leaks, mould, rotted framing, destroyed insulation and damaged ceilings.

Contractor quotations can often vary quite dramatically from each other and can be caused by a number of differing factors:

Contractors may adjust their prices depending on how busy they are and if they want to take on your project or not. Others might take a look at the size of the property and estimate how much they think you can afford to pay.

Rates will change according to the size of a business, a company with fixes assets and a workforce to pay might be more expensive than the local tradesman.

Some contractors will go in with a really low price and later on look to add these original savings back on with 'extras'

They might see plans, specs and vastly over estimate material quantities and labour costs.

Inexperienced contractors will tend to make serious omissions in there quotes.

To get an accurate quote first you'll need to work with your selected contractors and provide them with as much information as you can, this can include a full set of architectural drawings and plans, details of any materials you will be supplying or work you want to sub-contract yourselves and details on site access etc...

Armed with that information a contractor should be able to come back to you with a reliable quote that should detail a number of important elements including;


Materials

Getting Detailed Quotes From Your Roofing Contractor

Don't be afraid to ask roofing contractors to itemise not only the materials, but the cost of each item. Instead of giving you one figure for everything on the list, the contractor should bread down each item with a price. If most companies list your GRP roofing materials at similar prices but one lists the cost of the same brand at a substantially higher price, then that contractor could be over inflating the price paid.

Time & labour costs

Even if every one of the quotes you've received from your selected contractor say that it will approximately take 2-3 days to complete the installation of your new roof, you may not be getting the same amount of work from them. You need to make sure the quote states what times they work from and how many hours are they will be working on your project. Will they employ a professional or licensed installer to do the installation or if they will be subcontracting some of the work to temporary workers? One option is less expensive but may not have the experience to do the job correctly while the other will be more experienced but might charge more.

Clean up costs

The best roofing contractors that go the extra mile for there customers will always clean up after themselves as part of their service. If you come home to a well finished roof but the garden is littered with rubbish from the project, unless you make contact with the contractor and tell him the job hasn't been completed there's not a lot you can do other than clean it up yourselves.

To avoid this, always make sure every quote includes the cost (if any) for clean up and disposal of all old materials and any scrap or excess new products left over from the installation.


Having a detailed quotation without asking tells you a lot about the quality of the contractor you've chosen. The more up front the contractor is before the work has even begun sets you up for a good working relationship and hopefully a quality job that will last for many years to come.
