The Full general Rule of Thumb

Equally a general guide, y'all tin can repair most flat roofs if:

• the leak is caused by an affect such every bit a slipped tile, a tree co-operative or the similar
• the leak is acquired past a one-off hole, tear or localised issue that is isolated and not indicative of a more widespread trouble

Y'all are probably wasting your fourth dimension and coin trying to patch repair a apartment roof that is:

• very old and has leaks in multiple places
• that is bowing, dipping, bending or buckling between the joists
• where the unabridged surface has deteriorated due to age or UV damage

Of class, many people do bear out patch repairs on such roofs, but they are doing so at great risk.

Considering these roofs are flat they often hold water, especially during spells of heavy pelting, even a small tear or hole could cause a pregnant amount of water to enter the property.

Mutual Issues and What to Await For

Regardless of the type of flat roof material that is used, leaks are often:

• located near a join or seam
• where the felt has pulled free from the vertical wall
• acquired by the failure of the supporting timber decking underneath
• fabricated worse by water discharging onto the roof from a rainwater pipage
• fabricated worse by water pooling on the roof when it should ideally discharge off the roof

The photo below may help with troubleshooting:

Torch-on bitumen felt

1. check where the felt has been inserted into the wall, thermal movement may pull the felt out of the brickwork.
2. check all seams/joins near any leaks, if the felt hasn't adhered sufficiently information technology may allow water to pass through.
3. can the rainwater pipage exist relocated or an additional pipage laid beyond the flat roof to minimise the amount of water (and thus wear and tear) on the roof?

Lead Roofs

Below are two photos showing damage caused past squirrels that had migrated from woodland only across the road.

This type of harm is very common, it's too frequently seen effectually chimney pb flashings on houses in rural areas.

and:

If left unchecked, this damage could lead to rotten timbers and a leak onto the ceiling.

Below are our suggestions to repair this blazon of damage:

Temporary repair – cover the damaged surface area with a specialist lead sealant such as this to keep out whatever rainwater until a more permanent solution tin exist applied.

Longer term fix – a roofer with atomic number 82 welding skills could hands repair this damage or the damaged section tin exist cutting abroad and a new department fitted with folds. This would negate the need for costly welding.

Permanent solution – as the atomic number 82 roof is showing signs of damage to several areas and the leadwork around the nearby chimney has also been chewed. A permanent solution would be to supplant the roof with something less appealing to the squirrels such as a bitumen-based flat roof material.

For the chimney flashing, it could exist replaced with a lead alternative such equally Ubiflex – www.ubbink.co.britain/products/Covering/Non-lead-flashing

The reason why squirrels chew pb isn't entirely clear. Some say it's considering they are attracted to the sweet sense of taste while others advise information technology'south considering they demand to sharpen their teeth.

Whatsoever the reason, the use of lead should be minimised if the property is located most woodland.

Farther reading and photos can be constitute on this academy website.

For leadwork to large areas that take split, the best bet is to cut in an expansion joint. This work should exist washed past someone with experience in leadwork.

Bitumen Flat Roof Repairs

Bitumen based flat roofs come in two different flavours:

• one-time fashioned "pour and roll"
• a more mod "torchon" arrangement

The two photos below explain the difference:

Both types of felt will final between 15-25 years and there are some situations when they tin can exist repaired:

Splits and Small-scale Holes in Felt

For splits and small holes in the flat roof consider the following types of repair:

Temporary repair – for a quick fix that is cheap and can be washed by anyone with DIY skills, first dry and thoroughly clean the area and and then utilize two or three layers of Thompsons Roof Seal.

Medium term repair – if yous want a longer term repair and then dry/make clean the expanse and use one layer of common cold bitumen followed by a layer of scrim (aka webbing or mesh) for reinforcement and some other final layer of cold bitumen. See cold bitumen hither and over here yous tin can see scrim/mesh. In that location is an instructional video on Youtube that explains how to repair a flat roof with scrim and sealants.

Long term repair – to maximise the life of the roof without replacing it, torch a new height layer (cap canvass) onto the roof. Because this work involves a gas-powered torch, it will demand to be done past a professional.

Dips and Bowing Felted Roofs

If the felt is showing signs of bowing downwards between the timber supports and then in our opinion, repairs are a waste of time and money.

As the roof continues to dip/bow, whatever repairs will tear apart and the leaks will resume.

Because you have roof timbers, decking and potentially ceiling boards and plaster nether the roof, it's just not worth trying to save money by repairing a roof that is in this state. By missing an opportunity to supervene upon the roof, yous could end up with significant and costly damage to the timbers or plaster should the roof suffer a major leak.

A better solution would be to remove the felt layer, inspect the decking underneath and replace any boards as required before laying a new felt roof.

(Update May 2022: Nosotros've heard reports of insurance companies refusing to pay for damage caused by one-time leaky flat roofs that should have been replaced years ago then if your flat roof looks annihilation similar the 1 in the photo above, y'all should really get it replaced)

Fibreglass Flat Roof Repairs

Fibreglass roofs are generally very long-lasting and also await appealing every bit they don't have any joints or seams.

One of the well-nigh common issues with this material is that it tin suffer from splits.

This rarely happens on pocket-size roofs such every bit those found on porches but is ofttimes seen on very large areas such as double garages.

The skillful news is that fibreglass can be easily repaired.

All in one fibreglass repair kits cost less than £xxx and information technology takes less than an hour to seal over a hole, carve up or crack.

There are plenty of instructional videos on Youtube simply in a nutshell, the post-obit steps should be taken:

• clean area thoroughly
• sand with a coarse sandpaper
• clean with acetone
• chopped strand matting is and then laminated into place

Mastic Asphalt Roofs

This type of flat roof is expensive and should last for decades.

It's considered by many in the trade to exist the "Rolls Royce" of apartment roof materials.

Unfortunately, because it'south not very flexible and is very heavy, any motility of the roof beneath may result in splits and cracks.

Cracked mastic asphalt flat roof

There are several repair options available to you just the following two are best:

• add an extra layer of mastic asphalt – this should exist done later reinforcing the area around the crack to prevent it from transferring into the new layer.
• torch on a layer of bitumen felt,  either as a patch repair or to the whole roof. If the appearance of this felt is an issue, it, along with the residue of the roof, can be painted with a grey/argent reflective coating.

Epdm/Rubber Roofs

This blazon of fabric, known colloquially as a "rubber roof", is quick to install and doesn't crave a gas-powered rut torch.

While the material itself is long-lasting, weak points are usually located at the joints and upstands.

Pocket-sized holes, rips and tears, whether at the joints or as a result of touch on damage, tin be easily repaired by applying one of the post-obit:

1. by applying a dedicated rubber sealant such as this Firestone sealer. This is a brusque term repair but for very small holes, information technology may last for decades.
2. by using a sealing tape such every bit this Firestone flashing record. This is a long term set and should terminal every bit long as the roof.

The expected repair time is effectually one hour and that includes locating the leak, cleaning/drying the area and apply the sealant or patch.
