Why do bad weather conditions weaken roofs?

The roof is the building's first line of defense against the elements. During a strong wind, roofing elements can shift, lift, or become dislodged. After a hailstorm , some tiles may crack, break, or lose some of their structural strength. Sudden temperature changes, meanwhile, put stress on the materials and can exacerbate existing weaknesses.

A displaced tile, a damaged slate, deformed flashing, or a deteriorated underlayment can be enough to compromise the roof's watertightness. The problem is that leaks don't always appear immediately. Water can seep under the roof covering, reach the insulation, accumulate in the attic, or cause visible damage several weeks after the weather event.

For owners, property managers, building managers, and local authorities, these problems are not limited to the roof. They can also affect thermal insulation, promote the development of humidity, gradually weaken the roof structure, and reduce the building's energy efficiency.

What signs should raise concern after a storm or hailstorm?

After severe weather, certain signs should prompt you to have your roof inspected. These signs may be visible from the outside, noticeable in the attic, or appear inside the house.

The main warning signs are:

• tiles that are displaced, broken or missing;
• cracked or misaligned slates;
• a deformed, detached or obstructed gutter;
• a damaged gutter;
• traces of dampness in the attic;
• halos on the ceiling or on the walls;
• a persistent musty smell;
• a cracked or displaced ridge;
• damaged flashing around a chimney or a singular point;
• pieces of tiles, slates or zinc found on the ground.

Even without a visible leak, preventative inspections can be beneficial after severe weather. Slow-moving water seepage may initially go unnoticed, but can later cause more significant damage to insulation, ceilings, or the roof structure.

Roof maintenance: why check before making emergency repairs?

The press release comes in the wake of Storm Pedro, which has highlighted the vulnerability of roofing materials to extreme weather. The argument put forward is that post-disaster intervention does not replace a strategy of regular maintenance and inspection.

Roof maintenance involves identifying weak points before they cause serious damage. This includes checking the condition of roofing materials, flashing, the ridge, rainwater drainage systems, and other critical points.

This approach applies to both individual homes and buildings managed by real estate professionals. For an owner-occupier, it helps avoid costly emergency repairs. For a property manager or asset manager, it helps plan interventions, secure the building, and limit the risk of damage.

Regular roof maintenance thus becomes a matter of asset management as much as a maintenance operation.

What roofing elements should be checked after bad weather?

After an episode of wind, hail or heavy rain, several components require special attention.

Tiles, slates and roofing elements

Mechanical tiles, flat tiles, slates, or zinc roofing must be inspected for movement, cracks, breaks, or misalignment. A single displaced tile can be enough to create a water leak.

Zinc work, gutters and downpipes

Gutters, channels, downspouts, valleys, and flashings ensure water drainage. If they are deformed, blocked, or poorly fixed, water can stagnate or seep into sensitive areas.

The ridge and the singular points

The ridge beam ensures the junction between two roof slopes. Chimneys, skylights, ventilation outlets, and roof connections are also vulnerable areas. These critical points must be carefully inspected, as they are potential sources of leaks.

The underlayment and insulation

The underlayment reinforces the building's protection against water penetration under the roofing material. When damaged, improperly installed, or aging, it no longer performs its function correctly. The attic insulation can then be exposed to moisture, reducing its thermal performance.

Damaged roof: remember to file a report and contact your insurance company.

If there is visible damage after severe weather, it is recommended to document the situation. Photos of the roof, fallen debris, signs of dampness, or interior damage can facilitate the insurance claim process.

A roofer's intervention then allows for an assessment of the cause of the problems, securing the roof, and distinguishing between urgent repairs and more comprehensive restoration work. This step is important to prevent a temporary repair from masking a larger problem with the waterproofing, the metalwork, or the structure.

Couv'Habitat strengthens its presence in Seine-et-Marne

In line with its commitment to prevention and local intervention, Couv'Habitat announces the opening of a new warehouse and office on a 2,500 m² site at 14 Avenue de l'Épi in Rozay-en-Brie. This site now houses the company's administrative and logistics teams, historically based in Gretz-Armainvilliers and active in Ozoir-la-Ferrière and the surrounding towns.

This facility aims to respond more quickly to the demands of owners, real estate agencies, trustees and local authorities facing needs for roof diagnosis, maintenance or repair.

An organization designed to meet the needs on the ground

According to Couv'Habitat, several difficulties regularly arise during discussions with owners, real estate agencies, trustees and local authorities: delays in obtaining quotes, follow-up on files or variable quality of interventions.

The company explains that it has structured its organization to ensure comprehensive management of requests and more continuous support for projects. The teams are composed of roofers and sheet metal workers who graduated from the Compagnons du Devoir school and have over twenty years of combined experience. The work is advertised as being covered by a ten-year warranty, and the company states that it can provide a quote in less than 24 hours.

"We're breaking the mold completely to restore the prestige of this passionate profession! That's why we send out our quotes on the same day we conduct our site visit."

Interventions covering all components of the roof

The offer presented covers the main works related to the protection of the building envelope. It includes in particular the installation of underlayment, blown insulation, the installation of rock wool, ridge renovation as well as roofing work on slate, interlocking tiles, flat tiles or zinc.

The company also works on zinc roofing projects, installing or repairing zinc, PVC, or aluminum gutters, installing downspouts, and locating leaks. The press release also mentions the installation of cladding and solar air extractors to contribute to the thermal comfort of homes.

These services address several operational objectives: preserving the building's watertightness, improving thermal comfort, limiting energy losses and ensuring efficient rainwater drainage.

A company born from a need identified in the field

Couv'Habitat was created following interventions carried out by Prop'Habitat, some of which revealed specific roofing needs. According to the press release, this new structure was established to centralize these requests and apply a level of organization comparable to that already developed within Prop'Habitat.

The management is ensured by Arnaud Dufour , General Manager, a roofer-zinc worker trained at the École des Compagnons du Devoir, and Marlon Arruabarrena , CEO also at the head of Prop'Habitat.

The increasing frequency of extreme weather events serves as a reminder that the roof is a crucial element in a building's long-term viability. For homeowners, property managers, and real estate professionals, regular maintenance, preventative assessments, and appropriate interventions are key to minimizing the risk of leaks and ensuring the building's performance over time.
