I have a Velux in a pitch roof in a 3 story Victorian home. It's in the hall/landing area which is an open zig zag staircase from ground floor to roof. Although it doesn't leak, the cob webs (too high to reach them!) blow in winds (we're on sea front and with mountains behind so gets v windy). The hall/stairs at the top floor is always much colder. It's about 15 yr old I think. Is it a simple case of changing the seals or do I need to replace the whole thing - probably lost more than the cost of it in heat over the 6 yrs of being here!
Thx
