Save Money

You can probably save some money. This is the most common reason why many people decide to install their own roof. When you do it on your own, you can cut corners wherever you need, choose the type of materials you want to use, and get it done at your leisure.

A contractor is likely to charge you more money. Most contractors choose to work only with certain brands of roofing materials and might not agree with your choice of materials.

The total cost of the project is also likely to go up depending on the number of days it will take the contractor to finish the job and the number of workers employed to get the job done.

Sense of Accomplishment
As a DIY enthusiast, you know that nothing can match the feeling when you successfully complete a project on your own, especially if it is something as complicated and labor-intensive as roofing. This again is the reason why many people love to try their hands at installing and repairing roofs.


Safety Hazards
Have you ever been on the roof long enough to find out if you are comfortable staying up there for any length of time? Climbing on the roof and staying there for a few minutes is completely different from tearing off old shingles or installing new ones, or even just coating your flat roof.

Depending on the height and angle of your roof, you could feel dizzy and disoriented after some time, at which point a gust of wind is all it takes to knock you off the roof.

Even professionals and experts with a number of years of experience work on a roof ONLY if they have a harnesses and all the other safety gear in place. If you do not have this kind of safety equipment, roofing becomes a very, very risky business.

Labor Intensive
Have you ever heard the saying that time is money? Your time may be worth more $ than what you would pay a contractor to do your roof!

You will have to walk over the roof, pick up and install shingles, and do lots more, all of which is extremely difficult if you are not accustomed to it.

You could opt for hired help to assist you in the roofing job, but you need to make sure they can coordinate with you, are ok with the risks and that is just more money out of pocket.

Requires Technical Know-How
Laying shingles, coating roofs and installing more technical types of roofing like single-ply or metal roofing requires a great deal of technical know-how. There are so many minor details involved in the process that a novice would never know. Not to mention the fact that the whole process needs to be completed as quickly as possible to minimize exposure to the elements.

To complete a task as complicated as roof installation in a short period of time requires lots of knowledge, training, experience, and a team of workers who can coordinate with each other well.

Additional Costs
Not everyone is likely to have all the tools and equipment required for a roofing job. For instance, you might have to rent a dumpster. You are likely to need pneumatic nail guns and a compressor. You might have to install a drip edge, apron and vents. All of these might cost you a lot of money and end up stretching your initial budget considerably.


High Quality and shorter finish times

A team of roofing experts can do a top-notch roofing job and get it done much faster than any DIY enthusiast.

Workmanship Guarantee 
A professionally completed project is generally guaranteed against workmanship defects. Cool Roof Hawaii typically offers a 7 year workmanship warranty, under which we fix any problems arising out of poor workmanship at no cost to you. The State of Hawaii contractor laws allows roofing contractors to offer a maximum of 7 years.

Mitigation of Property Damage
When you install a roof, even the tiniest of mistakes could result in property damage. You could damage your lawn and shrubbery by carelessly tossing the shingles around; you could drop a shingle right onto your siding, fence, stairs, or deck and end up damaging it inadvertently. Negligence or damages not excluded from the roofing contract typically are covered by the contractors General Liability insurance

DIY vs. Professional Roofing Installation – Which is the Better Choice for You?
Roofing, simply put, is a task better left to professionals. It is way too labor intensive and risky and requires a good deal of technical expertise and experience. The money you spend in hiring a reliable roofing contractor is well worth it, as you will have a solid roof that will last for years to come.
