Is moss causing problems on your roof?

Are you unhappy with the state of your roof? Do you have moss causing problems on your roof?  A new roof is expensive so what are your options?

What can I do if I cannot afford a new roof?

This completely depends on the roofing material and state of the roof timbers. If the timbers are rotten, unfortunately you need a new roof asap and some form of financing is recommended if this is unaffordable.

If, however, your roof has concrete tiles and under 80 years old there may be a cheaper alternative to re-roofing or re-tiling.

How does moss damage my tiles?

Mosses are small flowerless plants that typically grow in dense green clumps or mats, often in damp or shady locations. Mosses do not have seeds but release spores to reproduce and spread and can cause numerous problems on a concrete tiled roof.

Firstly, clumps of moss hold water against the tile which can enter the roof area, causing damage to roof timbers. In winter, the moss will freeze and cause direct damage or erosion to the tiles over time. Moss will utilise all shaded areas and will grow between and under the tiles pushing them up and apart, subsequently increasing the chance of water leaks.

Indirectly, the moss is a food and water source for many birds. They will tear the moss off the tile and this pulls a small area of sand face off the tiles, increasing its porosity and subsequently the risk of water eggression and frost damage.

The weather will force the moss to fall. It will then enter your guttering and drainage system causing further structural issues on your home.

The moss will fall to the floor or on a flat roof and quickly establish and spread there. When wet it becomes very slippery under foot.

The obvious thing to do is to remove the moss but be careful! Removing moss in the wrong way can cause more damage than leaving it in situ. For instance, inexperienced workers can walk in areas they should not be near, breaking more tiles than they are cleaning. Also, the moss sometimes prevents your roof from leaking by absorbing the moisture. By removing it all in one go, your roof can suddenly fail leading to very expensive roof repairs or sometimes a total replacement.

So, what can I do?

Luckily, there is a solution that will solve all of these real issues at a fraction of the cost of a new roof.

We use innovative coatings that repel water, prevent further moss and lichen attack while returning your roof to its original and beautiful appearance.

Firstly, we have to do the dirty work – cleaning the roof. Our specially trained roofing teams will power wash the roof removing all organic material, pollution and dirt off the roof. We will protect the surrounding area and fully clean up afterwards including all guttering, windows and walls.

Secondly, we will carry out any repairs that arise from the first stage. Our roofing team will repoint all ridges, gables and valleys where needed and replace all broken, cracked and chipped tiles.

Thirdly, we will spray the roof with a biocide. This will kill all lichen and moss spores and prevent further attack.

Finally, the magic! We spray the roof with two generous coatings of specially formulated roof coatings from Ren-O-Tec. This will create a concrete tile that actually repels water off the surface. This results in no water or frost damage on your roof. It comes in natural colours that return your roof to its original appearance, negating the need to re-roof or re-tile. It also prevents moss growth on your roof for years to come.

All of this at a fraction of the cost of a new roof!

Iron Staining Disclaimer: Rust staining or Iron staining is a natural problem that can occur when specific individual stones within the product that have high iron content are exposed to the environment. This problem is often increased if the site is in an exposed or coastal region. It is not unusual for the problem to take a number of years to be exposed and there is no way of identifying if the aggregate is affected prior to application.

It is not possible to screen the iron content out of the product by using magnets as it is part of the chemical makeup of the aggregate. The aggregates affected by this problem are mostly flint or gravel based type products or aggregates that have usually been quarried from glacial or river deposits. Using Calcined flint aggregates will not eliminate this problem if the raw flint used already has high iron content.

Given that iron staining is a natural occurrence no guarantee can be given or liability accepted for areas affected by iron staining. Since 2016 The Home Improvement Project have only selected aggregates from quarries that have proven records of low iron content. Whilst iron staining can cosmetically spoil the appearance of the affected areas it has no detrimental effect on the render itself.
