When it comes to major home repairs, installing a roof is as significant as it gets. Though a new roof is not very glamorous, you will hugely understand its importance of selecting the right roof replacement shingles.

Making the wrong choice could result in allowing water to destroy the interior of your house, from the attic insulation, down through the remodeled kitchen, right on through into the basement living room using a big-screen TV. Home issues can be more devastating than a collapsed roof.

Roof replacement is not something to take lightly, nor is it a repair that should be delayed. When you sense that your roof is nearing the end of its useful life, brush up before soliciting bids.

Since a roof is old, it does not imply it is not in good condition.  A roof replacement will give your existing roof a brand new life for the next several years. It’ll allow you to plug up any openings or holes in your present roof shingles to prevent any water leakage from passing through. This will help avoid harm to the timbers underneath and keep any moisture from dispersing. 

Replacing the complete roof of a home will be more costly than a re-roofing, but it provides you ultimate benefits.

How Long Does a Roof Last?

According to the insurance companies, there are two major factors while examining the age of any roof and they are;

1. Covering Type

Roofs fall under one of three types: normal/standard roof shingles, architectural roof shingles, or tile.

Standard Roof Shingles: Standard roof shingles butt up against each other, giving the roof a flatter, uniform shape, and are predicted to continue up to 15 years.

Architectural Roof Shingles: Architectural roof shingles overlap each other, giving the roof a textured, three-dimensional look.  All these are expected to continue around 25 years.

The Tile Roof: The tile roof is made of either concrete or clay and comes in different shapes and textures. Tile Roof is typically more durable than other roof shingles and is deemed to have a life expectancy of 30 years.

This does not indicate that your roof will begin collapsing after 20 years. However, these guidelines have become standard in the insurance business, so your roof age will need to fall within these ranges for you to be issued coverage.

2. Roof Shape

The thing your insurance carrier will consider is the shape and slope of your roof.  A roof’s shape affects drainage as well as how much occurs. Most insurance businesses tend to prefer hip roofs (where all four sides of the roof incline downward), but gable roofs (where two sides slope downward) will still protect you and your loved ones.

Flat roofs are somewhat rarer in the state of Florida; they are more difficult as they do not allow rain to run off as other roof types to insure. 

What are the reasons and why you should need to replace a roof?

Roof replacement or installation is a significant investment that has a big influence on the appearance, value, and function of your home. If you rent out a home, are planning on selling your house, or your roofing is over 20 years old, we suggest having your roof inspected to assess any damage and determine if the roof can be repaired or if it’s time to get a new roof.

A roof offers a fantastic deal of financial security to some potential home buyers, as the owner will not have to worry about roofing problems or roof replacement for over at least the next 20+ years.

Apart from having a leaky roof, there are several common reasons homeowners want to have a new roof. Roof shingles last anywhere from 15 to 25 years. Factors like storm damage slope, ice damming, and mold or moss growth can significantly shorten the life span of any asphalt or 3-tab roof so that is why it is highly suggested by experts to use lifetime roof instead of using 3-tab or any asphalt roof replacement shingles.
