My fundi had discouraged me as there was more work for him.

True you will need more nails and more fundi time. As @kwanini has said straightness depends on the cross members and all other supports.

Just 2 tips from me.
1. buy long blue gum pieces i.e 15ft and above only. Short ones are a headache to keep joining.

2. For the wood where the tiles will be nailed on, dont use blue gum. The nails will damage the tiles as possibility of nails bending is very high. If this happens leaks will be constant in yr house.


You are spot on bro,i did my roofing and blundering sometime late November using the same.When you decide to use the blue gum, take the fundi to choose the right quality and the end product will not disappoint.
Advice is like snow.The softer it lands the harder is sticks.

To deal with warping,twisting,driving nails thro' fundis recommend you do the trusses before the Bgum is dry. To avoid splits they "tie" tha trusses with iron hoops. Due to the weight, u can downgrade the cross members by an inch or so. Sagging happens if the Cross members are poorly done. For me B.Gum any time.


Just because it is cheaper??.Before i go that way,consider this.If you roof your house with not so well seasoned timber,you pay the price in terms of shrinkage.....Just how did i leave that out??......In a risk/benefit Vs cost analysis,cypress takes it any day and the only other wood which comes close despite being a hardwood is Lusiola (Markhamia lutea.Popular in Western and Nyanza and also referred to as Omwobo in Ekegusii.Quite common in Siaya,Gem and Karachuonyo)....If you ever get this for your ceiling,floor and half walls....woow!Fantastic stuff!

did mine 6 years ago and the roof has a finish like anyother. Dont regret at all. i got the timber from blue gum that was grown on hardy/rocky soil. If the b.gum is grown in swampy area it will split and bend.

the diff is span or lentgh and supports that go with it. in my village almost all roofing is done in bluegum and i have done a descent house using it. As s'one has pointed, it can sag and twist and is hard to drive nails if "too" dry. Incidentally b.gum has several varieties and depending on which variety your timber comes from, you may experience few or many of issues associated with it.
