Roofing Felt Life Expectancy

Or it may not come close to how long other flat roofing systems last.

Roofing felt life expectancy.

Because it is a single ply material rolled roofing has a shorter life than strip shingles which generally last 15 to 30 years. Expect a lifespan for rolled roofing of five to 15 years although roof helper says the lifespan is typically less than 10 years. If well installed and maintained roofing felt could last longer but it will require time and money to keep it in a decent state. But it is my general impression that it is the lifespan of the underlayment that governs the life of the roof.

Despite no authoritative answer on the life of the system there are many spf roofing systems that when coated and maintained properly have lasted 50 years giving spf the longest roofing system lifespan of all common roofing materials. When and why condensation occurs inside buildings explains the problems caused by excessive indoor condensation explains how moisture enters building wall and ceiling cavities. When to replace your tile roof underlayment the most common underlayment felt has a lifespan of about 12 to 20 years. Concrete tiling tends to be around 50 less and has a lifespan of approximately fifty years although despite having a similar appearance to clay.

Also for the majority this life cycle is already ideal due to their future plans and priorities. Clay tiling has the advantage of being more durable and long lasting than concrete and because it wears so well it can add much to the resale value of a home and may well last 100 years or more. If the underlayment is brittle from age then as happens frequently here in rainy season the roof is bound to leak regardless of the asthetic covering tile shingle etc. When it comes to a felt flat roof s lifespan the majority of guarantees will only last for ten years.

Torch on roofing life expectancy may not be as long lasting as you may have expected. It is not uncommon for a well installed built up roof covered with tar and gravel for protection from sunlight and properly drained to last for 40 years. However a torch on roofing does have qualities that compensate its shorter life service. If the underlayment gets brittle at 15 years it doesn t.

Life expectancy of built up roofs a rule of thumb used by some roofers is to estimate that the typical life expectancy of a built up roof will be 5 x the number of plies installed. Concrete is a much more durable roofing material with a life expectancy of 35 50 years. The use of roofing felt or 15 pound felt as a building house wrap or vapor barrier and the permeability moisture problems and indoor condensation problems that may occur vapor barriers and condensation in buildings. Thermoplastic olefin membrane is another flat roof option made.

Rolled roofing is low cost and reasonably resistant to weather. It typically has a lifespan of 40 to 50 years although most manufacturer warranties only guarantee a lifespan of 10 to 15 years.
