The Basics of Roofing Drainage

In order to ensure water flows freely down and off a roof, the Building Regulation’s Approved Document H outlines the minimum required fall or slope a roof should have. R

Roof moss removal Stockport has listed the variances depending on the type of roof material below:

Aluminium – 1:60

Copper – 1:60

Lead – 1:120

Mastic asphalt – 1:80

Roofing felts – 1:60

By ensuring your roof has the adequate fall you’ll be sure that surface water isn’t getting stuck and pooling on your roof. This build-up of water can result in subsurface soaking and dampness within the roof, only making it easier for moss to grow.

Designing Moss-Free Gutters

While many people don’t see the harm in a bit of moss build-up on their roof, they immediately begin calling roof moss removal Stockport when it begins accumulating in their gutters. Gutters that are clogged with moss won’t drain properly and will result in water damage, with some gutters even collapsing under the excess collected water weight.

When planning or checking your gutters, always make sure there are at least two drainage points. While two is the minimum, three is recommended in order to allow for continuous outflow even if one of the holes gets blocked or clogged. While this next tip might seem obvious, there are many people who neglect the importance of outfitting their rainwater pipes with leakproof joints.

Maintaining Moss-Free Gutters

The above tips will prevent moss build-up, but what if you’ve already got a green infestation all over your roof and gutters? First of all, call roof moss removal Stockport to clear the moss from your roof, and follow up with either a gutter-guard or filter to protect your gutter in the future. No matter which option you pick, make sure you regularly check the state of your filter or gutter guard. Cleaning them out regularly rather than having to unclog a major blockage is always the way to go.
