Understanding the lifespan and common issues associated with different roofing materials is crucial for homeowners. A well-maintained roof protects your property and ensures you remain comfortable and dry inside your home. In this article, we'll explore the longevity of felt flat roofs and other roofing materials, as well as solutions to common roofing problems. At FixTrade (https://www.fixtrade.co.uk/collections/roofing-accessories-tools), we offer a range of roofing products to help you maintain and repair your roof effectively.
The Lifespan of Felt Flat Roofs
The lifespan of a felt flat roof can vary depending on several factors, including its age, condition, and the type of felt used. Historically, flat roofs were constructed using either pour-and-roll or torch-on roofing felt, and the quality of the felt could vary significantly. These roofs were often installed to minimise costs.
Premium felt roofs are constructed with multiple layers and can last up to 20 years. The vulnerable areas, referred to as "laps," are where water can penetrate, leading to potential leaks. Regular inspection and maintenance are essential to prevent further damage and prolong the roof's lifespan.
Over time, water can infiltrate through joints in the felt roof, especially when rainwater pools on the surface. Once water enters, it can cause moisture to expand, leading to potential failure. If the felt starts deteriorating, it becomes more susceptible to cracking and leaking, indicating the need for replacement.
Roofing Material Alternatives
With the growing popularity of flat roofs in recent years, many homeowners opt to replace ageing and deteriorating fibreglass flat roofs with a more durable solution, fibreglass-reinforced plastic (GRP). While these roofs are highly resistant to leaks, proper installation is crucial. Identifying and repairing leaks in GRP roofs can often be done quickly.
In cases where repairs to small areas of a felt roof do not resolve the issue, a full roof replacement may be necessary. Installation errors, such as using boards that were not completely dry when installed, can be the root cause of the problem.
Repair and Maintenance Products
FixTrade offers a range of products for temporary repairs to flat roofs, including the Cure It range of GRP materials. These can extend the lifespan of your roof. Waterproof paints are also available to prevent water from leaking into areas where the roof is deteriorating. While these products can last for up to five years, they do not come with a guarantee.
Pitched Roofing Materials and Their Longevity
When dealing with pitched roofs, various materials can be used to create a new roof. Ageing or defective slates or tiles can lead to leaks in pitched roofs. Most clay roof tiles come with a 30-year manufacturer's warranty, but some remain in excellent condition even after a century.
Older clay tiles, particularly those predating the 1980s, may be susceptible to frost damage, resulting in cracks and leaks. These older tiles did not meet the same standards as modern roofing materials, which are designed to last longer.
Modern roofing materials adhere to European Union and UK standards to ensure their longevity. If your clay roof tiles begin breaking, it's a clear sign that a replacement is needed. Once a few tiles start cracking, it's advisable to inspect the rest of the roof for potential issues.
Concrete Roof Tiles
Concrete roof tiles can be in good condition for approximately 50 years but are often in poor shape after about 60 years due to their susceptibility to frost damage, cracking, and thinning. These tiles are more prone to damage from wind and rain. When they appear pale, it's time to consider a replacement.
Clay Roof Tiles
Clay roof tiles can last a long time, especially those made from Welsh slates, which can endure for over 200 years. However, if delamination or cracks develop, it's a clear sign that replacement is necessary.
Choosing Slates for Pitched Roofs
When dealing with leaks in pitched roofs, consider choosing slates instead of concrete or clay tiles. Lead flashing around windows and chimney pots is a common source of leaks due to thermal expansion causing mortar cracks. Flexible sealants designed for this purpose can address this issue effectively.
Leaks from chimneys made of brick can be prevented by using masonry sealants that waterproof the brickwork. In cases where leaks occur at the verges of slate and tile roofs, the use of plastic dry verges, as mandated by building regulations, provides a long-lasting waterproof solution.
