How Long Does a Roof Last?

Roofing is an ornament that protects the house and its owners. It withstands the onslaught of cold, scorching rays, storms, hail. Owners of cottages are always interested in how long the roof will last without major repairs.

In this article we will understand what determines the durability of the roof, what will last longer and how to increase the service life.

What factors influence the average service life

The material from which the roof is made has the greatest influence on the service life of the roof. Each roof covering has its own degree of durability. We will dwell on the advantages of materials a little later, but now we will consider what other factors have an impact.

Initial material quality

Even at the procurement stage for construction, it can be seen that one type of roofing is available on the market in different price categories. Let’s take metal sheets as an example.

More expensive will be the material with:

greater thickness;
polymer coating;
additional stiffening ribs.

Each of the parameters increases the durability of metal. In the same way, the price of other types of roofing materials is formed. The better, more reliable roofing, the longer it will last.

Substrate

A substrate is laid between the outer frame and the floor slabs on the house itself. It has the effect of protecting the structure from moisture, condensation vapors.

The substrate includes:

frame of framing, counter-batten;
hydroinsulation layer;
insulation;
vapor insulation.

If one of the layers is installed incorrectly or is missing, the roof will last less.

Mounting

It is important to follow the installation rules when assembling the structure, laying the roof covering. The choice of contractor depends on how reliably the work is carried out, the materials selected.

Before signing a construction contract, it is worth evaluating reviews of the selected company, studying examples of finished projects, learning about the warranty on the work, construction.

Climate peculiarities

When choosing a material, you need to consider the climate of the region. For example, Cape Cod has snowy, windy winters. The roof must be able to withstand strong storms, hail strikes. Small scratches on the metal can become a hotbed of corrosion, and on the shingles in potholes mold, fungus, moss begins to grow.

Roofers should install protective elements such as snow guards. Mechanical damage can cause damage to the integrity of the coating. Cracks will be dangerous because of possible leaks, which in a short period of time can damage the ceiling slab, load-bearing walls.

Color

The color of the coating also plays a role in the durability of the roof. In regions where hot sunny days prevail, light colors are more often chosen for the roof.

Dark colors absorb heat, heat up, which causes microcracks, deformations, ruptures. Because of them there are leaks, there are violations of thermal insulation, ventilation. But in northern regions, such roofs reduce heating costs.

Slope

Sloping or flat roofs without maintenance suffer more from the accumulation of moisture, snow and debris. Such structures must be equipped with good drainage systems, otherwise mold, fungus, and then corrosion or rot will appear in the recesses, at the joints, fasteners – depending on the type of coating.

Steep slopes better resist precipitation, but suffer more from storm winds. Architects should be consulted when drawing up a project: they can advise you on how to minimize the effects of climate.

Ventilation

Roofing is the exterior protection of a home that ensures proper attic ventilation.

A reliable air cushion helps prevent:

condensation accumulation;
wear and tear on the ceiling materials;
excessive overheating or freezing of the space, which provides – normal operation of air conditioners, heaters.

At the first signs of violation of ventilation, call the master to inspect the roof. It is worth paying attention to:

moist spots on the ceiling;
sagging roof;
peeling paint;
sharp temperature fluctuations inside the house;
appearance of ice build-up in winter;
damage to the roofing.

It is important to remember: violation of ventilation in the attic can turn into serious damage to the ceiling, load-bearing walls.

Timely service

The average lifespan of a roof will increase if you provide it with regular inspections and maintenance. Experts recommend inspecting the roof, making minor repairs once a year and after heavy storms. Leaves, debris, branches should be removed so that rainwater does not accumulate. The gutter should be cleaned periodically for the same purpose.

Trees near the house can create excessive shade. If the roof is almost no sunlight, it does not dry out, the risk of rot, mold, moss growth increases.

In gale force winds, which are not uncommon in Cape Cod, tree branches can severely damage your roof. Builders recommend regularly trimming trees that grow close to the house. Many damages can be prevented, which can help extend the life of your roof and avoid costly repairs.

How contractor warranties affect the longevity of a roof

Companies that are engaged in installation, give comprehensive guarantees that relate to the quality of work, reliability of materials. The project is drawn up taking into account the climatic peculiarities.

Usually the roof serves longer than the warranty period, and the contractor’s obligations contribute to:

confidence that in a difficult situation, when it will be necessary to repair or replace the structure, there will be professionals nearby;
responsibility for regular maintenance;
understanding that the work has been carried out to the highest standards, since the builder gives an impressive warranty.

It is important to remember that warranty service can relate to different situations: from wear and tear of materials to weather damage. You should carefully study the contract to know exactly when you can count on free repairs.

How long a roof can last

Let’s understand more about the service life of the roof. They directly depend on the choice of roofing. On average, their durability varies from 20 to 50 years. We are talking about the period during which no major repairs will not be required, provided timely maintenance and the exclusion of force majeure.

Durability of the roof depending on the roof type

The service life of the roof increases in proportion to the investment. The more expensive the coating, the higher the complexity of the construction, the more reliable the protection of the house.

Three-part asphalt shingles

Three-piece shingles consist of asphalt, a layer of adhesive with granules and a fiberglass backing.

The material is flexible, easy to process, so it is often used by those who perform roofing work with their own hands.

Low wind resistance makes three-section shingles are not the most reliable protection. According to the manufacturer’s estimates serves 15-20 years.

Wood shingles

Elements for wood shingles are usually made from cedar or pine. Properly treated pieces can last up to 30 years.

It is important to remember that wood is susceptible to rot, mold, mildew, fungus, needs protection from termites. Such a roof more than others requires attention, constant cleaning, painting.

Wood is a fire hazardous type of coating, does not always resist storm winds well.

Metal roofing

The thicker the layer of steel, the more reliable the coating. For protection, sheets are treated with polymers, which are responsible for resistance to:

mechanical damage;
influence of temperature fluctuations;
ultraviolet;
atmospheric precipitation.

Roofing from thin sheets will last 20-25 years. Durability of metal profile with a greater thickness can exceed 50 years.

Architectural asphalt shingles

Architectural asphalt shingles differ from the three-section asphalt shingles by a more complex structure. It has three layers of fiberglass backing. This makes it look bulkier and more aesthetically pleasing than the three-section.

Laminating several layers provides additional strength. The service life of soft tiles varies from 30 to 50 years – depending on the thickness and composition.

Composite tiles

These are elements that externally resemble wooden, slate or clay tiles. At the same time, the sheets are made of reliable steel, covered with a crumbled polymer.

Composite coating combines the durability of steel and the attractive appearance of natural materials.

Roofing is not as expensive as stone, not fire hazardous as wood. It reliably protects from snowfalls, storms, hail, serves 40-50 and more years.

Roofing slate

Slate shingles are rocks of stone, split into thin layers.

The material has high durability, so it can serve from 50 to 100 years, sometimes longer.

It is important to realize that roofing shale is more expensive and heavier than other types of shingles. Not all contractors work with natural stone. You should make sure that there are companies in your area that work with slate shingle roofing before putting together a project.

Not all homes can handle the weight of stone slates. Some will require the construction of additional support structures. It is imperative that you consult a structural engineer.

Concrete or clay tiles

Ceramic cement-sand tiles serve from 50 to 100 years. Such a roof is not afraid of frost, high temperatures. It is resistant to the vagaries of the weather of the sea coast. Materials are fire-safe, absorb noise.

Like slate, roofing made of clay or concrete has a lot of weight. Before making a final decision, it is necessary to make sure that the walls of your house will withstand such a load.

Flat roofs

Flat roofs are often constructed for commercial buildings and are covered with low-maintenance, long-lasting materials:

EPDM (ethylene propylene diene monomer) is a brightly colored, safe coating made from crumb rubber. With proper care, it lasts 25 to 30 years.
PVC (polyvinyl chloride) – Membrane roofing that consists of three layers with a durable mesh backing and polymer coating. Reliably protects against moisture, reflects sunlight. Service life of PVC-membranes – from 20 years.
TPO (thermoplastic polyolefins) – a composite material of rubber and polypropylene, where the first is responsible for plasticity, and the second – for wear resistance. The coating can last for about 20 years or longer.
Spray foam provides reliable seamless insulation for flat roofs, lasts for 50 years. Proper maintenance, including new coats every 10 to 15 years, is necessary for the roof to remain reliable.

PVC is considered the most expensive insulation for flat roofs in private and commercial construction.

How to prolong durability

The roof structure has an important task: to protect the house and its occupants. In order for it to remain reliable, it is necessary to remember the important, but simple rules of operation:

Even at the construction stage it is worth realizing that the roof – a long-term investment, on which you should not save money.
For installation, repair of the structure should hire companies that know about the peculiarities of the climate of the region, have long been working in the market.
Prevention is the best way to prevent a small problem from transforming into a major disaster. The National Roofing Contractors Association recommends inspections at least once a year. You should regularly clean debris, leaves and branches from the roofing and gutters.
To protect your roof from mold, rot, and mildew, you need a well-ventilated attic space and a properly installed underlayment.
It is necessary to monitor the condition of the rafter system, treat it with protective agents against rodents, termites, rot, fungus.
It is necessary to study the peculiarities of the material and type chosen for the roof, to learn about the subtleties of maintenance. For example, wooden roofs need periodic painting, and a roof with a slight slope – in cleaning from snow in winter.

Annual inspection of the roof can be done by yourself, but a professional eye will notice the smallest faults more quickly.

How often a roof should be replaced

We have sorted out the approximate lifespan of different types of roofs. Usually, the longevity of structures is much longer, can reach even a hundred years. But this is with proper maintenance and without emergencies, such as storms, heavy snowfalls and other vagaries of nature.

You should consider replacing your roof if:

there is noticeable damage to the roofing;
the ceiling leaks have become noticeable, the color of the decorative coating has changed, the paint has peeled off;
the ceiling ceiling joists are visibly sagging;
pests have entered the house in large numbers.

Special attention should be paid to structures that were erected more than 15-20 years ago.

At the first suspicions, experts should be called in.
