Most homeowners often take the protection over their heads for granted. However, as your home’s first defense against the wrath of Mother Earth, your roofing system is also the most vulnerable part of your home.  

While roofs are designed to last for decades, normal wear and tear and unexpected disasters can inflict damage on your roof, shortening its lifespan. This may have you wondering if it’s time to get a roof replacement or just a simple repair service.  

Understanding Roof Repair

For moderate to minor damages, a roof repair should be enough to stop further damage and resolve common roofing issues. Roof repair and maintenance can help restore your roofing and extend its lifespan.

It’s a project that almost every homeowner should deal with regularly. Roof problems, when caught early, can help prevent further damage. It often involves working on small, isolated areas of your roof. Depending on the damage, roof repair may include patching up minor holes and cracks and replacing missing or damaged shingles and other roofing materials.  

Understanding Roof Replacement

Repairing a roof means fixing a small part of the structure. However, if a large area of your roof needs to be repaired, replacing your roof system may be a more viable option. The roof replacement process means you have to strip off your existing roof and install a new one. It may also involve repairing rafters, sheathing, and trusses.

Roof Repair Vs. Roof Replacement: 6 Factors To Consider

Unlike re-finishing cabinets or re-painting your room, roof repairing and replacing are significant home improvement projects. You don’t want to do a quick repair on damaged spots only to find out the issue runs deeper or tear down your whole roof and spend thousands of dollars when minor repairs should be enough. If you’re wondering what to do with a damaged roof, here are essential factors to keep in mind.  

1. Age

As mentioned, roofs are designed to be durable and withstand harsh weather. However, nothing lasts forever. Every roofing material has its expiration or recommended lifespan, which you can use to determine which processes are necessary.  

Generally, if your roof is still years away from retiring, but you see damages, it may still thrive with minor patch-ups. But if your roof’s lifespan is almost over and you’re seeing signs of deterioration due to aging, such as sagging, replacing your roof may be a better investment.

2. Condition

Your roof’s condition or extent of damage is another factor that can help you decide between repair and replacement.  

If you have minor to moderate damage covering 30% of your roof, you can still try to fix it. However, note that some damages may not be obvious, so you’ll need to hire a professional roofing company.  

In contrast, replacing your roof is a more suitable option if the damage to your roof is too much, whether from a fallen tree or widespread deterioration of sheathing or metal rusting.

3. Cost

Roof repair and replacement are both expensive. However, roof replacement can be quite costly, with the prices going up to thousands of dollars. This depends on the roof’s size, the damage’s extent, and your location. This may be on the higher side for most people. If roof replacement is not within your budget, you should work with your roofing contractor to do some repairs until you are ready.  

Installing a new roof is obviously more expensive than simple roof repairs. In the US, roof replacement can cost you USD$5,500 to USD$11,000, with an average cost of USD$8,000. The good news is you’ll recoup some of the cost of tearing down and replacing your roof when you decide to sell your home. In fact, a roof replacement will return about 60% of its value when selling your home.  

However, if you don’t have the budget, roof repairs may be a better option to patch up issues with your roofing system. The typical cost of repairing minor roof issues such as broken shingles can cost you between USD$377 and USD$1,727. However, major roof repairs like fixing structural damage can go up to USD$7,500.

You may be able to lower your repair if you decide to go the do-it-yourself (DIY) route.  However, while repairs may be cheaper than replacement, the cost may pile up if you’ll need to do constant repairs.  

4. The Affected Area

The affected area of the roof is a good way to tell whether to repair or replace your roof. If the damage is limited to a small area, like a leak in the dining room, you only need to repair it, and you are good to go. However, installing a new roof will give you better service if the damage affects more than 3o percent of your roof.

5. The Length of Your Stay

How long you plan to stay in your house determines whether you need to repair or replace your damaged roof. When homeowners who have invested in several homes want to add value to their property, the roofing system is popular. Some call for immediate roofing upgrades, which in this case, will need roof repair.

Installing a new roof will take a longer time. Therefore, it is ideal for those houses that do not need immediate settlement. Depending on the complexity of the damages, the size of the roof, weather conditions, obtaining permits, and other approvals, roof replacement may take 20-30 days.

4. Why Is Replacing a Roof Expensive?

Every roofing contractor that you hire has operating expenses that must keep their business running. They also need to make profits. Some of these costs are fixed, while others are flexible. The size of the company determines these costs.  Some of the common roofing contractors’ operating costs include building and utilities, advertising and promotions, taxes, licenses and bonds, payrolls, and general liability insurance.

Labor and time also make the replacement of roofs very costly. Replacing a roof is labor-intensive, and therefore, it takes a lot of time. This increases the cost of replacing a roof significantly. There has also been a sharp rise in roofing materials due to their scarcity and higher demand than supply, which has increased prices.

The roofing material that you choose will adversely contribute to the cost of replacing the roof. Different materials come with different price points. For example, roofing tile is costlier than asphalt shingles.

5. What Are the Most Common Types of Roof Repairs?

1. Improperly Installed Flashing and Other Materials

Roof flashing or drip edge keeps water from running underneath your shingles. When this flashing does not adhere firmly to where it is mounted, water flows underneath the roofing material, which may cause them to rot. You must therefore replace your drip edges as soon as they start leaking.

2. Shingle or Tile Replacement

Natural elements like sun, wind, and natural disasters can cause damage to tiles and shingles. You will therefore need to repair granule loss, blistering, splitting, shrinkage, broken shingles, and lifted shingles.

3. Gutter Maintenance and Repair

Most gutters lack basic maintenance and routine cleaning. Debris, branches, and leaves can cause the gutters to overflow or detach from your roof. This can also cause the deterioration of your facia board. Observe routine maintenance of your gutter and replace them as soon as they detatch from your roof.

Ponding water can be caused by sun damage, weathering, poorly installed drains, or underlying structural issues. If left unrepaired, it can cause severe damage to the roof membrane and result in roof leaks.

5. Leaks

As the roofing materials start experiencing excessive wear and damage, they can cause water leaks which can damage your home. These leaks need to be repaired as soon as they occur to prevent adverse damage.

6. Poor Ventilation

Poor ventilation can cause your entire roof to deteriorate and suffer severe damage. It can also lead to high energy costs, paint damage, and leaks in the attic. Improving the ventilation of your house will prevent roof deterioration and hence reduce the costs of roof repairs.
