DIY: How To Reroof A Roof

While you might be able to patch the occasional leak on your own, DIY roof replacement isnt recommended. Roofing is a dangerous job, even on a single-story home, since youre working on a slanted surface, usually at least 10 feet off the ground. Professional roofers have substantial training, and also have safety equipment for working on steep roofs.

Roof installation also requires tools such as extension ladders, tear-off shovels, nail guns, air compressors, and more. Professional roofing companies will already have these tools and know how to meet local building codes. You wont have the benefit of a roof warranty if you do the project it yourself, and if youre using your homeowners insurance, the insurance company wont reimburse you.

Roof replacement is a highly skilled job and one of the largest home improvement projects youll encounter. We dont recommend attempting full or partial roof replacement on your own. Instead, hire a licensed roofing contractor with substantial experience in the industry.

Hiring A Roofing Company: Top Tips

Reroofing your garage is expensive, so you must ensure the professional roofer knows what to do. Here are a few essential questions to ask a prospective contractor.

  • Have they any references you can follow up on? Its the finished installation that matters. Therefore, you want to know that the roof looks good, is free from leaks and is correctly installed.
  • Some of the new roofing technologies need specialist equipment and knowledge. Therefore, ensure the contractor has relevant training and follows the industry codes of practice.
  • Is the contractor a member of a relevant trade association? The National Federation of Roofing Contractors and The Liquid Roofing and Waterproofing Association are good organisations to look out for. All trade associations insist their members follow their code of practice and work professionally.
  • Search the Competent Person Register for local authority approved contractors.
  • Ask for at least three quotes before you decide on the contractor. Insist they visit your property to inspect the existing roof. Therefore, avoid quotes over the phone without seeing the job.
  • Dont always go for the cheapest quote. Try to choose one somewhere in the middle.

Roof Replacement Cost By Material

The material has a tremendous impact on the total cost of the materials and labor. Some materials are exclusive to the roof type you have. For example, a flat-topped home uses specific materials that are not used on conventional slopes. However, most homes use asphalt shingles, metal panels, tiles or shakes made of several materials, or specialty materials like cedar or slate.

Each material has costs. The more features a material has, the higher its costs. For example, architectural shingles that help protect against hail damage have a higher cost than standard architectural shingles. Clay tiles cost more than concrete, while copper costs considerably more than aluminum. Rare materials like slate and copper cost more due to their availability. Materials that are harder to install, such as wood and some clay tiles, also have higher costs. Materials with additional benefits, such as energy efficiency, algae protection, hail protection, or rainwater management, also have higher costs.

When choosing a material, consider its costs, maintenance, and longevity. While slate is very expensive, it can last 200 years or more in the right circumstances with little maintenance. This can make it more of an investment than a less expensive material.

Roof Replacement Cost By House Size

The cost to replace or install a roof goes up as the home size increases. But note that your roof size won’t match the area of your house since you’ll need to take into account the overhang, which is how much the roof edge extends beyond the siding. While most homes have an overhang, the length will depend on the roof’s architectural style . You’ll also need to consider the pitch, which is a measure of how steep the roof is.

The estimates in the following chart are based on architectural shingles for a pitch of 4/12 on a single-story home.

Enter the approximate value for how many square feet the house has in the first number box.

Select how steep the roof is. A 4/12 pitch is relatively easy to walk, an 8/12 is very difficult to walk, and a 12/12 is impossible to walk.

Select the complexity of the roof. One roof line is simple, two to four roof lines is average, and anything over four roof lines is complex.

Choose whether or not your roof is new or will have multiple layers to remove.

Finally, choose what type of new roofing will be used.

This calculator is only an estimation. It is not as accurate as measuring each roof plane and adding the square feet together. It does take into account for an average number of offsets and an overhang. It also takes into account for the starters, the edges, and the ride caps. The squares returned include everything.

The formula for solving for the area of a roof involves climbing onto the roof. Measure each roof plane. For shapes such as trapezoids, triangles, and trapeziums, find the average length by finding the center of the width. Remember to add two feet for valleys. Add the square footage of all of the roof planes together. Divide this by one hundred for the number of squares. There are three bundles of shingles for each square.

To determine how many will be needed for starters and edges, measure the entire perimeter of the roof and divide it by three. Since there are twenty six shingles in a bundle of twenty year shingles , divide the result by twenty six.

Cost To Redo A Roof With A Different Material

First time to Re-Shingle a Roof (WnW #61)

Many homes have an existing roof of asphalt shingles. These are durable and lightweight, but some want to change the shingle type for a different look. In addition, many newer materials last much longer than asphalt while looking better. For this reason, many people reroof with another material, even if that was what was originally installed. The exact cost to reroof with another material depends on the material. Your costs could range from $6 to $25 a square foot for tear-off and installation plus the material costs, which can range from $1 to 15 a square foot for many common materials. Many materials are heavier than asphalt shingles. Concrete, tile, and slate require reinforcing your roof to ensure it can withstand the weight. This is done by adding additional rafters and joists to your roofs frame. So, you have an additional $1,000 to $2,000 in reinforcement costs.

When going from a heavier material like tile to a lighter material like architectural shingles, there is no need to change the frame, and your overall costs are lower.

Rv And Travel Trailer Roof Replacement Cost

This is an expensive process and usually involves a full replacement, including the roofing material and the under material.

Choosing A Trustworthy Roofer

Garage reshingle

Unless you personally know a contractor, the thought of finding a reputable company can be overwhelming, to say the least. Between horror stories of people getting blatantly ripped off, the fly-by-night crews and storm chasing contractors, it can be hard to know who you can trust.

Use these steps to find a reputable roofer:

1. Ask friends and family for recommendations.

If your friends and family dont know any good contractors they can recommend, then do some online research to identify top local contractors that seem transparent and have solid reviews across different sources.

2. Once you have a list of prospects, call them, and ask these questions:

  • Do they take on projects of your size? This one will almost always be a Yes, but it is a good starting point to get the contractors interest and attention
  • Can they supply a list of previous clients as references?
  • Are they willing to provide financial references from banks and suppliers?
  • How many other projects will they be working on while doing your roof?
  • Will they be using subcontractors? If so, how long have they worked with them?

This information will tell you how reliable they are, how much attention theyll give to your project and how smoothly the work will go.

3. From your phone conversations, choose three to four contractors to come to your home for estimates. Dont go on personality alone! Be sure to check their reputation with their past clients and/or BBB, rip off report, Angies List if you have it, etc.
