The roof is one of the most important parts of a home that is always neglected by most people until it springs a leak. There is no better feeling than having a roof over your head but when things go wrong with your roof, it’s important to handle the issue immediately.

Neglected issues like cracks or leaks in a roof can lead to water damage and rotting underneath the shingles and can eventually cause the ceiling on your home to collapse. It is necessary to inspect your roof twice a year, especially in the spring and fall seasons to determine the state of your roof.

Do you think you need your roof replaced and wondering how long it will take for the replacement? Replacing a roof can take as little as 2-5 days or can even take up to 3 weeks depending on the following factors.

Roof Complexity

This factor doesn’t only affect the time duration but also the cost of your roof replacement. Roof complexity determines the number of facets, angles, hips, valleys, and pitch. A roof with multiple facets is difficult to replace and time-consuming than a roof with few facets. So the more complex the roof, the more time it takes to be replaced.

Roofing Material

There are different types of roof materials and each type determines labor requirements. For instance, heavy slate tiles are difficult and time-consuming to replace when compared with basic 3-tab asphalt shingles.

Roof Accessibility

Once your roof is hard to access, it adds up time and could push back the timeline by a few hours or even a day. The roof replacement process requires removing the old or unwanted roof, disposing of them into the dump truck, and then getting the new materials back up to the roof for installation. So if your roof is accessible, it guarantees easy and fast installation. Learn more about the new roof cost in Ireland.

Climatic Condition

Roof replacement should be done in the right climatic condition because the weather is one of the determinant factors to how long it takes your roof to be replaced. For proper installation, it is not advisable to replace your roof in the rain, snow, freezing temperatures, or when it’s too hot.

For instance, imagine the condition of your home if while replacing your roof it rains. The installers will have no choice but to tarp your roof to protect your home and pick up where they left off next time it’s dry enough to be on it. Harsh weather extends the replacement process a little bit longer than expected.

Time Of The Year You Replaced Your Roof

Though it all depends on when you’ve been able to adequately plan to replace your roof, but the best time of the year to get your roof replaced is springtime. It might be too cold during the winter, summer can be too hot and fall can be too busy. So if you get your roof replaced during the winter, summer, and fall times it could take extra days to complete the process.

Different Roof Type And How Long It Take To Replace Them

Aside from the above factors that can affect the roof replacement process, the following is the list of different roof types and how long it takes to replace them.

  • Shingle    1-3 Days
  • Flat    2-4 Days
  • Tile    6-9 Days
  • Rubber    1-2 Days
  • Natural Slate    6-7 Days
  • Synthetic Slate    3-5 Days
  • Tin    1-3 Days
  • Wood Shake    3-4 Days

Why Do I Need A Roof Replacement?

The need for roof replacement is based on the integrity and functionality of your roof. Here are some reasons why you might need a roof replacement.

Your Roof Is Old

After 25-50 years of a roof being in use, it is necessary to know if there is a need for replacement. The lifespan of a roof varies depending on the location and materials used.

Missing Or Curling Shingles

The missing or breaking apart of shingles in your roof valley makes your roof vulnerable to leak and once it is in excess, roof replacement may be needed. The valleys are one of the most crucial parts of a roof. So cleaning your shingles the right way can prevent premature wear.

Your Gutters Full of Shingle Granules

Roofs tend to wear out once they reach the end of their lifespan, losing more granules which often end up in the gutters. If you check and your gutters and downspouts are full of these granules, then there may be a need for roof replacement.

Sagging Roof

Once your roof starts sagging or dropping, it is a sign of a serious structural issue that needs urgent action. So before the problem spreads all over the roof, there is a need for replacement before further damage occurs to your home.

Damaged Flashing

Damaged chimney flashing needs to be replaced once noticed because it could lead to leaks. There is a need for a metal flashing system if your flashing is made of tar or cement for its durability.

Moss on Roof

Having moss on a roof is a result of trapped moisture and this can ruin a roof. Remove the moss that collects in shaded corners of your roof using a stiff brush but be careful to treat any underlying issues during the process.

Discolored Walls or Ceilings

The presence of water stains and discoloration in your walls and ceilings is an indication that there is a serious issue that needs to be resolved.

For all of the above reasons, you need the assistance of a licensed roofing contractor to get a professional opinion on whether you are to repair or to have a full-on roof replacement. The fact that there are few damaged shingles or a bit of a leak, doesn’t make for a whole new roof replacement.

How Much Does It Cost For Roof Replacement?

The extreme effect that comes from weather, fire, or general wear and tear sometimes may lead to roof replacement. A Roofing job that takes a day is less expensive than a job that takes days. The square footage of your home (your roof), and the type of roofing material you choose are the two important variables mostly considered by the roof installers. It is incredibly difficult to estimate the exact cost of a new roof, but as a guideline starting price, you’ll want a budget of at least €3000, as the typical price range goes from €2500 to €50000+ dependent on project size and complexity.

Factors That Can Increase Your Roofing Labour Price

Some factors that tend to increase the price charged for your roofing labor are as follows:

The extent of the damage

When the timbers underneath the shingles are excessively damaged, it makes the job more difficult and dangerous too. So due to the extra time and equipment used to ensure their safety while completing your roofing replacement, the professional may increase the cost.

Removal of old material

If your home requires more than one layer of shingles to be removed to repair or replace the roof, this, of course, will be reflected in the roofing labor cost per square foot.

Environmental conditions

Extreme harsh environmental conditions can increase the rate you’ll pay for your roof replacement job, especially when your roof installer has to bring in protective measures for the team.


The cost of roofing materials is typically about 40% of your roof replacement cost. In conclusion, it is advisable to go for quality and not a quick job. The hired roof installer is expected to get the job done promptly while still maintaining the quality you expect when you invest in a roof replacement. If the main aim of the roof installer is to get your job done quickly, there will be a lot of mistakes that will show soon after the work is done. Detail attention is needed to achieve the expected result.
