Some Things to Consider Before Replacing Your Flat Roof

Replacing your flat roof is going to be the massive investment in your home. However, it is vital to know the pros and cons of roof placement to make the right decision. If your flat roof is getting deteriorate or old, then it is the best time to replace it.

It is vital to replace your roof when it gets old because a flat roof is more prone to the damage due to heavy rainfall and storm as compared to others. Moreover, you can consult with an experienced roofing expert to complete the replacement process efficiently. Here, in this article, we are going to discuss some things that you have to consider before the flat roof replacement process.

1. Slope

The slope is going to play a vital role in your roof that tells how well your roof sheds water. However, if there are fewer roof slopes, then it can cause water ponding and some other water damages.

Keep in mind that the flat roof is not entirely flat. If there is no slope on your roof, then you will see water standing and resulting leakage. However, your flat roof must have some slight incline that will allow the rainwater to flow off from the house through the drainage system.

If your flat roof does not contain any slopes, then it could result in extensive leakage. Make sure that incline must be a minimum of 1/4 per foot to reduce water ponding and prevent subsequent leaks.

2. R-value

R-value is going to determine how much money you have to pay to heat or cool your home. So if the R-value is higher, then the insulation ability of your roof is better. However, if your roof’s slope is adequate, then it will improve the R-value.

Using tapered insulation can be a cost-effective decision than altering the roof. Moreover, adding thickness to the taper is going to be the best way to insulate your roof. So, start determining the R-value before going through a flat roof replacement process.

3. Roof drainage

You have to look out your gutters and roof drainage system to prevent the water from standing on your roof. If there is a blockage in your drainage system, then it will result in water sitting on the top of the roof after heavy rainfall.

Further, this water ponding is going to lead to extensive leakage. However, the water will seep through ceilings and can encourage mould and mildew growth in your walls. You can consult a professional roofing company if your flat roof not set up for proper drainage.

4. Structural loads

Determining the structural loads is another vital thing before replacing your flat roof. You have to worry about the structural damage to your house with all the extra structural weight.

So it becomes vital to pay attention to the structural load of your flat roof. For example, you can not use the built-up roof on your home because it will be heavier than other types of roofing materials.

5. Roof deck condition

As we all know, the roof deck supports your flat roof. So it is vital to determine the roof deck condition before replacing your flat roof. Make sure that your roof deck is in good condition.

However, if your roof deck is not strong enough, then it becomes difficult to support your flat roof. If you notice any damage, corrosion, water ponds and separation, then you should consider replacing your roof deck.

Final thoughts

The purpose of this guide is to provide you with some vital things that you have to consider before having a flat roof replacement. However, replacing your roof is an extensive financial decision. But if your roof is getting old and deteriorating, then it becomes vital to replace your flat roof because a flat roof is more prone to damage than other types of roofs.
